(WSJ) New Ultrasound Therapy Could Help Treat Alzheimer’s, Cancer

Ultrasound, the decades-old technology known for giving early glimpses of unborn babies, could hold a key to a problem that has long challenged drug developers: getting medicines to hard-to-reach places to treat diseases like Alzheimer’s and cancer.

A cutting-edge approach that combines ultrasound waves with tiny bubbles of inert gas injected into the bloodstream can get more chemotherapy to tumor cells and enable drugs to breach one of the most stubborn frontiers in the human body—the blood-brain barrier. It is also being explored as a new way to deliver gene therapy.

“There’s an extremely wide variety of where this sort of drug delivery or augmentation with ultrasound and bubbles can take us,” says Flemming Forsberg, professor of radiology and director of ultrasound physics at Thomas Jefferson University in Philadelphia. The effectiveness of drugs in treating diseases like cancer, Alzheimer’s and Parkinson’s is often limited by poor penetration into tissues, he says, whether in the brain or in tumors in other parts of the body.

(Vatican News) Cardinal Czerny urges concrete action to save our common home

Cardinal Czerny first looked at the new geological epoch of today, called the anthropocene, which has brought about “a staggering turning point in the history of our planet.” Human beings, Cardinal Czerny recalled, have significantly altered all planetary systems: the atmosphere, oceans, continents and ecosystems. What is unprecedented in our time is the combination of various crises, including the ecological crisis, cultural wars, the plight of hundreds of millions of poor people and refugees, and the digital age, with its opportunities and pitfalls.

The Prefect of the Dicastery for Promoting Integral Human Development went on to emphasise that in Pope Francis’ encyclical Laudato si’, he urges us to take into account all aspects of the global crisis linked to climate change and to reflect, in particular, on the cornerstones of an “integral ecology for a new humanity.”

(Local paper) Charleston, South Carolina presents next steps, negotiation opportunities for $1B sea wall

After debate on Charleston City Council began to stir over the next steps for a proposed 8-mile sea wall around the peninsula, city officials presented a timeline for the project, as well as opportunities for negotiation.

Dale Morris, the city’s Chief Resiliency Officer, told members of a newly formed citizen commission July 27 that the city should be finalizing a design agreement with the U.S. Army Corps of Engineers, the federal partner on the project, in the next few months.

The agreement will dictate some broad priorities for the project, as well as the roles the two government agencies will play in the design process.

(Local paper) Gulf Stream and Atlantic ocean current system could collapse, causing seas to rise in South Carolina

The Gulf Stream is a mighty river in the ocean that powers past South Carolina with such force and momentum that it sucks water away from our coast, lowering our sea level by as much as 3 feet.

It’s also part of a much larger conveyor belt of warm and cool waters called the Atlantic Meridional Overturning Circulation, or AMOC, a current system that moderates the Northern Hemisphere’s climate like a radiator in a car.

But because of a rapidly warming planet, the AMOC system could collapse between 2025 and 2095, researchers said in a new study published in the journal Nature Communications that’s raising alarms across the globe.

(Local Paper front page) Waterway Woes–Filbin Creek in North Charleston is filth, tests show

Water samples raised alarms about Shem Creek in Mount Pleasant and James Island Creek years ago and spurred action.

But more recent testing shows Filbin Creek, where people fish, boat and crab, is far more polluted.

In one June test covering fecal bacteria, Filbin Creek’s reading was more than 120 times the state water quality standard, and no tested creek in the Charleston area has so consistently had bacteria levels exceeding the state standards.

(NYT front page) Starving Orcas and the Fate of Alaska’s Disappearing King Salmon

In the waters of Puget Sound outside Seattle, 73 beloved and endangered orcas, known as the Southern Residents, are on the hunt, clicking. Using sound like a searchlight, they patrol the chilly depths. When they locate a target, they dive, sinking sharp white teeth into their preferred food, the fatty coral-colored flesh of king salmon.

But in recent weeks, this ancient rhythm of the Pacific Northwest was being negotiated not just at sea but also in a federal courtroom in downtown Seattle, where on May 2 a district court judge issued an order effectively shutting down Alaska’s biggest king salmon fishery, one of the largest remaining in the world.

To the Wild Fish Conservancy, the Washington State-based environmental group that filed the lawsuit, the fates of the two totemic animals are intimately bound. The orcas need the salmon to eat, and if we stop fishing them, the conservancy argues, we save the whales.

(CSM) Computer-generated prayer? How AI is changing faith.

Some religious leaders have embraced ChatGPT as part of their efforts to engage with communities in innovative ways. In Germany, a Lutheran church recently offered a service created mostly by an AI chatbot. People packed the pews to listen to the experimental service, which was led by an avatar on a screen above the altar.

Religious organizations and leaders in the United States have utilized the emerging technology to a lesser degree. Rabbi Yonatan Dahlen, at Congregation Shaarey Zedek in Michigan, says some of his Christian counterparts have used it for correspondence, marketing, and social media content.

At the same time, many spiritual leaders are wary of AI and believe it has limitations. Mr. Dahlen says he once tried using ChatGPT to write a D’var Torah, a short teaching about a passage of the Torah. He feels that a good D’var Torah comes from vulnerability and human experience. “AI can’t do that,” Mr. Dahlen says.

Dayal Gauranga is the executive director of Manhattan’s Bhakti Center, which represents Hinduism’s tradition of Bhakti Yoga. “What makes something powerful is when there’s a lived experience of something,” he says. “You’re not going to get that just by generating a message about it.”

(NYT) Can A.I. Invent?

…can A.I. invent?

Legal scholars, patent authorities and even Congress have been pondering that question. The people who answer “yes,” a small but growing number, are fighting a decidedly uphill battle in challenging the deep-seated belief that only a human can invent.

Invention evokes images of giants like Thomas Edison and eureka moments — “the flash of creative genius,” as the Supreme Court justice William O. Douglas once put it.

But this is far more than a philosophical debate about human versus machine intelligence. The role, and legal status, of A.I. in invention also have implications for the future path of innovation and global competitiveness, experts say.

(Bloomberg) AI Doomsday Scenarios Are Gaining Traction in Silicon Valley

Controversial AI theorist Eliezer Yudkowsky sits on the fringe of the industry’s most extreme circle of commentators, where extinction of the human species is the inevitable result of developing advanced artificial intelligence.

“I think we’re not ready, I think we don’t know what we’re doing, and I think we’re all going to die,” Yudkowsky said on this week’s episode of the Bloomberg Originals series AI IRL.

For the past two decades, Yudkowsky has consistently promoted his theory that hostile AI could spark a mass extinction event. As many in the AI industry shrugged or raised eyebrows at this assessment, he created the Machine Intelligence Research Institute with funding from Peter Thiel, among others, and collaborated on written work with futurists such as Nick Bostrom.

To say that some of his visions for the end of the world are unpopular would be a gross understatement; they’re on par with the prophecy that the world would end in 2012. That prediction was based on a questionable interpretation of an ancient text, as well as a dearth of supportive evidence.

NASA Reveals Webb Telescope’s First Images of Unseen Universe

The dawn of a new era in astronomy is here as the world gets its first look at the full capabilities of NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and CSA (Canadian Space Agency).

The full set of the telescope’s first full-color images and spectroscopic data, which uncover a collection of cosmic features elusive until now, released Tuesday, are available…[there.

“Today, we present humanity with a groundbreaking new view of the cosmos from the James Webb Space Telescope – a view the world has never seen before,” said NASA Administrator Bill Nelson. “These images, including the deepest infrared view of our universe that has ever been taken, show us how Webb will help to uncover the answers to questions we don’t even yet know to ask; questions that will help us better understand our universe and humanity’s place within it.

(NYT) David Wallace-Wells–Global warming is accelerating, and it’s starting to show

It is always comforting to believe disasters are far away, unfolding elsewhere, but increasingly doing so means defining ever smaller increments of space as distant. In this case, New Yorkers drew comfort from the fickle path of a single local storm system. The rains had pulled just a few miles west, on Sunday, sparing New York City and instead pummeling Vermont, where government buildings acquired new moats, Main Streets became canal towns, and ski resorts were flattened by brown by muddy rubble. People were kayaking through Montpelier, and the Winooski River rose to levels not seen since catastrophic flooding in 1927. The governor had to hike his way to an open road.
It didn’t even seem that freakish, all things considered — we see so many more climate-fueled disasters now, with global average temperatures breaking records every day recently. There were terrifying floods this week in Himachal Pradesh, in India, where several bridges collapsed and others carrying dozens of cars and trucks seemed about to. Japan experienced the “heaviest rain ever,” and in Spain, floodwaters carried cars backward through traffic at rapid speeds, their drivers simply watching powerless from the roof, where they’d taken refuge when the water began filling the cabin. A monthslong heat wave centered on Texas and Mexico and spread outward as far as Miami, which, as of Monday, had reached heat indexes north of 100 degrees for 30 straight days. In Death Valley in California, this week temperatures may reach or surpass the global record of 130 degrees Fahrenheit, set just in 2021. In El Paso, there hasn’t been a day that didn’t hit 100 for weeks.
Off the coast of Florida, the water was nearly as warm as a hot tub — 95 degrees according to one buoy, 97 degrees according to another. It was just last month when life-threatening heat indexes as high as 125 simply parked in Puerto Rico for days on end. According to a coral bleaching forecast published by the National Oceanic and Atmospheric Administration, there is likely to be bleaching across the entire Caribbean this summer. It’s not clear how much will survive. According to some estimates, as much as 50 percent of the world’s oceans will experience marine heat wave conditions this summer; normally the figure is about 10 percent.

(The State) For decades, South Carolina farmers have fertilized fields with sludge. It could be having toxic impacts

For years, farmers across South Carolina have used sludge from factories and sewage plants to fertilize the fields where crops grow and cattle graze.

Applied to thousands of acres since the 1990s, the sludge is billed as a cheap way to enrich the soil.

But increasingly, chemicals suspected of causing cancer, high cholesterol and other health problems are being found in the mucky waste. Scientists, environmentalists and some farmers worry that the pollutants in sludge, called PFAS or forever chemicals, are contaminating drinking water, poisoning crops and sickening people.

“We’re talking about cancer-causing chemicals that can get into surface water and, therefore, into drinking water systems or in fish people eat,’’ said environmental lawyer Ben Cunningham, who has pushed the S.C. Department of Health and Environmental Control to tighten state oversight of sewer sludge.

C of E General Synod calls on Church and Government to move faster on climate emergency

The Church of England’s General Synod has called for renewed action from the Church and Government to tackle the impact and causes of climate change.

A motion brought by the Diocese of Oxford calls on all parts of the Church to review policies and procedures in order to give due priority to creation care, and asks the Government to review planning regulations to aid the installation of renewable technology on church buildings that are listed or in conservation areas, was passed by a substantial majority of Synod members.

It also commends the National Investment Bodies for their decisions to divest from fossil fuels, calls for regular prayer, and encourages the opportunity for confirmation candidates to make commitments to safeguard the integrity of creation.

Ahead of the vote, Synod members were briefed on the aspects of the motion which have made positive progress since the motion was passed by Oxford Diocesan Synod in March 2020: including the Church of England’s Routemap to Net Zero by 2030 and announcements by the National Investing Bodies to disinvest from fossil fuels.

(NYT front page) Globally, the Heat Hasn’t Just Been Scalding, It’s Setting Records

The past three days were quite likely the hottest in Earth’s modern history, scientists said on Thursday, as an astonishing surge of heat across the globe continued to shatter temperature records from North America to Antarctica.

The spike comes as forecasters warn that the Earth could be entering a multiyear period of exceptional warmth driven by two main factors: continued emissions of heat-trapping gases, mainly caused by humans burning oil, gas and coal; and the return of El Niño, a cyclical weather pattern.

Already, the surge has been striking. The planet just experienced its warmest June ever recorded, researchers said, with deadly heat waves scorching TexasMexico and India. Off the coasts of Antarctica, sea ice levels this year have plummeted to record lows.

(NYT) Barred From Grocery Stores by Facial Recognition

Simon Mackenzie, a security officer at the discount retailer QD Stores outside London, was short of breath. He had just chased after three shoplifters who had taken off with several packages of laundry soap. Before the police arrived, he sat at a back-room desk to do something important: Capture the culprits’ faces.

On an aging desktop computer, he pulled up security camera footage, pausing to zoom in and save a photo of each thief. He then logged in to a facial recognition program, Facewatch, which his store uses to identify shoplifters. The next time those people enter any shop within a few miles that uses Facewatch, store staff will receive an alert.

“It’s like having somebody with you saying, ‘That person you bagged last week just came back in,’” Mr. Mackenzie said.

Use of facial recognition technology by the police has been heavily scrutinized in recent years, but its application by private businesses has received less attention. Now, as the technology improves and its cost falls, the systems are reaching further into people’s lives. No longer just the purview of government agencies, facial recognition is increasingly being deployed to identify shoplifters, problematic customers and legal adversaries.

(Local paper front page) South Carolina coastal cities prepare for Fourth of July holiday and ‘dirtiest day on the beach’

“It’s amazing what trash is left in our parks, both on our beach and in the interior of the park,” Wilson said, adding that park rangers cannot issue littering citations. “So much work goes in from volunteers to staff, both in parks and on the beach, just picking things up.”

In the U.S., the upcoming Fourth of July holiday typically brings millions of visitors to coastal beach areas for holiday festivities. The significant amount of litter and trash left behind has led the California-based Surfrider Foundation to dub July 5 as the dirtiest day on the beach.

Wilson, who has worked at the park since 1994, said she is bracing herself for what she will find that day. She urges the public to pick up their trash in order to protect the environment.

“A lot of times, we just throw up our hands and think, ‘What can I possibly do? I’m just one person.’ But everybody can make a difference,” Wilson said. “If you pick it up, that means an animal won’t.”

(NYT front page) Russia is Building A Vast Industry Of Spying Tools

As the war in Ukraine unfolded last year, Russia’s best digital spies turned to new tools to fight an enemy on another front: those inside its own borders who opposed the war.

To aid an internal crackdown, Russian authorities had amassed an arsenal of technologies to track the online lives of citizens. After it invaded Ukraine, its demand grew for more surveillance tools. That helped stoke a cottage industry of tech contractors, which built products that have become a powerful — and novel — means of digital surveillance.

The technologies have given the police and Russia’s Federal Security Service, better known as the F.S.B., access to a buffet of snooping capabilities focused on the day-to-day use of phones and websites. The tools offer ways to track certain kinds of activity on encrypted apps like WhatsApp and Signal, monitor the locations of phones, identify anonymous social media users and break into people’s accounts, according to documents from Russian surveillance providers obtained by The New York Times, as well as security experts, digital activists and a person involved with the country’s digital surveillance operations.

(Church Times) David Westlake–Your online scammer could have been trafficked and tortured

We all receive scam messages — and I cannot be alone in noticing that they are becoming more frequent. Last month, several UK banks gave warnings about a sharp increase in online fraud.

It disturbs me that anyone will go to such lengths to steal my money; but what has chilled me to the core is learning that the person on the other end of a scam call or message could be a victim of human trafficking — forced into involvement in fraud by the threats of beatings and electrocution.

My colleagues at International Justice Mission (IJM) in Cambodia were some of the first people to respond to this sinister new form of modern slavery, forced scamming. Human traffickers are luring people with false job offers online, paying their transport costs, and then trapping them in heavily guarded compounds in places such as Cambodia, Myanmar, and Laos.

Under the threat of extreme violence, the victims must scam people all around the world. Survivors whom we have helped have shown us bruises the size of watermelons caused by being beaten, and burns from electrocution — the result of not hitting their scamming targets.

Disturbingly, forced scamming is one of the most complex and fast-growing forms of modern slavery in the world.

(Local paper front page) Charleston band hosting beach cleanups along East Coast tour route

A gloved hand digs through the sand around a plastic water bottle, prying the piece of trash from the clutches of the shoreline and depositing it safely into a green trash bag alongside a hodgepodge of other debris.

An orange grabber snaps down on a cigarette butt in the dunes, separating it from the tangles of seabeach evening primroses and firewheels blossoming along the mounds.

While children play with shovels and buckets and balls, a boy around their age beside them bends down to rescue the sea turtles from one of the many bits of left-behind litter that will eventually turn into microplastics and scatter the Lowcountry’s beachfronts, marshways and ocean floors. He was among about 30 volunteers who signed up for this particular beach cleanup on Isle of Palms on a sunny summer Sunday morning.

The cleanup is one of four that Charleston band Easy Honey has helped organize along the East Coast in the coming months as part of their five-week Surf Tour that coincides with the release of new EP “Ooooo.” In between playing 20 shows along the coast, they will stop in Wilmington and Beaufort, N.C., as well as Portland, Maine, to pick up trash along waterways.

(BI) Researchers uncover new CRISPR-like system in animals that can edit the human genome

A team of researchers led by Feng Zhang at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT has uncovered the first programmable RNA-guided system in eukaryotes — organisms that include fungi, plants, and animals.

In a study in Nature, the team describes how the system is based on a protein called Fanzor. They showed that Fanzor proteins use RNA as a guide to target DNA precisely, and that Fanzors can be reprogrammed to edit the genome of human cells. The compact Fanzor systems have the potential to be more easily delivered to cells and tissues as therapeutics than CRISPR/Cas systems, and further refinements to improve their targeting efficiency could make them a valuable new technology for human genome editing.

CRISPR/Cas was first discovered in prokaryotes (bacteria and other single-cell organisms that lack nuclei) and scientists including Zhang’s lab have long wondered whether similar systems exist in eukaryotes. The new study demonstrates that RNA-guided DNA-cutting mechanisms are present across all kingdoms of life.

Church of England Pensions Board disinvests from Shell and remaining oil and gas holdings

The Church of England Pensions Board is today announcing its intention to disinvest from Shell plc and other oil and gas companies which are failing to show sufficient ambition to decarbonise in line with the aims of the Paris Agreement.

The new investment restriction announced today will apply to all oil and gas companies that do not have short, medium and long term emissions reduction targets aligned with limiting global warming to 1.5°C, as assessed by the independent Transition Pathway Initiative. The exclusion will apply to equity and also debt investments.

“Today we announce our intention to disinvest from all remaining oil and gas holdings across our equity and debt portfolio,” said John Ball, Chief Executive Officer of the Church of England Pensions Board. “There is a significant misalignment between the long term interests of our pension fund and continued investment in companies seeking short term profit maximisation at the expense of the ambition needed to achieve the goals of the Paris Agreement. Recent reversals of previous commitments, most notably by BP and Shell, has undermined confidence in the sector’s ability to transition”.

(Proto.life) Are Industrial-scale Stem Cells Here?

The hopes and dreams of regenerative medicine and the use of stem cells to treat or cure diseases have been a beacon of promise for 25 years. But after a roller coaster ride of scientific breakthroughs, clinical setbacks, policy wrangles, and an explosion of suspiciously charlatan clinics pushing unproven treatments, we are mostly still waiting for those cures.

Now bit.bio, a synthetic biology company focused on human cells and headquartered in Cambridge, England, has presented new data at the 2023 annual meeting of the International Society for Stem Cell Research (ISSCR) conference last week in Boston that showed they can engineer stem cells with what they are calling an unparalleled level of consistency. Company officials say their achievements in the last few months will set a new standard for the manufacture of human cells, calling their innovation so disruptive they claim it will do for stem cell biology what CRISPR has done for genetics.

Bit.bio’s achievement builds on the pioneering work of Shinya Yamanaka, a professor at Kyoto University in Japan and a senior investigator at the Gladstone Institutes in San Francisco, who discovered how to transform ordinary mature adult skin cells into more primitive precursor cells, which look and act like the sort of embryonic stem cells found in the early states of embryonic development in the womb.

(Church Times) Commissioners and Pensions Board take a scythe to their oil gas portfolios

The Church Commissioners and the Church of England Pensions Board are to remove Shell, BP, and other oil and gas firms from their investment portfolios, because they are not reducing their carbon emissions quickly enough.

The investment bodies were instructed by the General Synod in 2018 to disinvest from fossil-fuel companies by 2023 unless the latter could prove that they were on the path to tackling climate change, in line with the Paris Agreement (News, 13 July 2018).

The Commissioners, who manage a £10.3-billion endowment fund, announced on Thursday that they had “decided to exclude all remaining oil and gas majors from [their] portfolio, and will exclude all other companies primarily engaged in the exploration, production and refining of oil or gas, unless they are in genuine alignment with a 1.5°C pathway, by the end of 2023.

“In 2021, the Church Commissioners excluded 20 oil and gas majors from [their] investment portfolio. [They are] now also excluding BP, Ecopetrol, Eni, Equinor, ExxonMobil, Occidental Petroleum, Pemex, Repsol, Sasol, Shell, and Total, after concluding that none are aligned with the goals of the Paris Climate Agreement, as assessed by the Transition Pathway Initiative (TPI).”

(Washington Post) Hidden Beneath The Surface of The Earth, Clues to our Real Ecological Situation

This summer, researchers will determine whether Crawford Lake should be named the official starting point for this geologic chapter, with pollution-laden sediments from the 1950s marking the transition from the dependable environment of the past to the uncertain new reality humans have created.

In just seven decades, the scientists say, humans have brought about greater changes than they did in more than seven millennia. Never in Earth’s history has the world changed this much, this fast. Never has a single species had the capacity to wreak so much damage — or the chance to prevent so much harm.

“It’s a line in the sand,” said Francine McCarthy, a professor of Earth sciences at Brock University in Ontario, who has led research on Crawford Lake. “The Earth itself is playing by a different rule book. And it’s because of us.”

(WSJ) DNA tests are uncovering a generation of biological fathers and half-siblings who stretch the bounds of what makes kin

Five years ago, Tiffany Gardner learned she had another father. She already had two.

One had colon cancer and died when Gardner was 4 years old. Her adoptive father taught her to drive and walked her down the aisle at her wedding. At 35 years old, when Gardner received news of a third, “I remember the room spinning,” she said.

Gardner had been in her mother’s kitchen. During the conversation, her mother let go of a long-held secret about the man Gardner had long believed to be her father. He was in an accident, her mother said. He had to relearn how to walk and talk. I couldn’t get pregnant. The doctors said the accident had likely left him infertile. We used a sperm donor.

“I felt I was falling backwards trying to process the moment,” recalled Gardner, a lawyer in the Atlanta area and the mother of three boys. Among her feelings was a desire to meet her newly uncovered biological father. It didn’t take long to find him online.

(NYT) Quantum Computing Advance Begins New Era, IBM Says

Quantum computers today are small in computational scope — the chip inside your smartphone contains billions of transistors while the most powerful quantum computer contains a few hundred of the quantum equivalent of a transistor. They are also unreliable. If you run the same calculation over and over, they will most likely churn out different answers each time.

But with their intrinsic ability to consider many possibilities at once, quantum computers do not have to be very large to tackle certain prickly problems of computation, and on Wednesday, IBM researchers announced that they had devised a method to manage the unreliability in a way that would lead to reliable, useful answers.

“What IBM showed here is really an amazingly important step in that direction of making progress towards serious quantum algorithmic design,” said Dorit Aharonov, a professor of computer science at the Hebrew University of Jerusalem who was not involved with the research.

(Guardian) Synthetic human embryos created in groundbreaking advance

There is no near-term prospect of the synthetic embryos being used clinically. It would be illegal to implant them into a patient’s womb, and it is not yet clear whether these structures have the potential to continue maturing beyond the earliest stages of development.

The motivation for the work is for scientists to understand the “black box” period of development that is so called because scientists are only allowed to cultivate embryos in the lab up to a legal limit of 14 days. They then pick up the course of development much further along by looking at pregnancy scans and embryos donated for research.

Robin Lovell-Badge, the head of stem cell biology and developmental genetics at the Francis Crick Institute in London, said: “The idea is that if you really model normal human embryonic development using stem cells, you can gain an awful lot of information about how we begin development, what can go wrong, without having to use early embryos for research.”

(SA) At Last, Astronomers May Have Seen the Universe’s First Stars

The James Webb Space Telescope (JWST) was built primarily to transform our understanding of the early universe. Less than a year after it was switched on, it is delivering, finding galaxies earlier in the universe than any seen before. Yet the telescope has another, less publicized goal in probing those earliest moments after the big bang 13.8 billion years ago. It is hunting for signs of the first stars to switch on in the universe, so-called Population III stars, gigantic balls purely made of hydrogen and helium that shined brilliant and brightly to first bring light to the cosmos. “They’ve been sort of in the background,” says Garth Illingworth of the University of California, Santa Cruz, largely because finding them is so difficult. No definitive detection of such stars has ever been made, but we know they must exist. Now two new results are bringing us closer than ever before to their discovery.

In a pair of papers posted on the preprint server arXiv.org, two teams of astronomers report promising signs of Population III stars. In the first study, led by Roberto Maiolino of the University of Cambridge, researchers think they may have found a pocket of Population III stars nestling in the outskirts of a remote galaxy. The second study, led by Eros Vanzella of the National Institute for Astrophysics in Italy, hints at a tiny galaxy that may be composed of, if not Population III stars per se, extremely primordial stars born early in the cosmos. “These papers quite nicely highlight the different aspects of the search,” says Jorryt Matthee of the Swiss Federal Institute of Technology in Zurich, who was not involved with either paper. “We’re almost there.”

Bp Graham Usher–Why are we supporting the People’s Plan for Nature?

Sadly, much of this wildlife is at risk from climate change and associated biodiversity loss. The UK is one of the most nature-depleted countries in the world. 15% of all our species are threatened with extinction, 97% of our wildflower meadows have been lost since the 1930s, and we have lost 492 animal and plant species in England since the 1800s. This can be even more pronounced on a local level – since 1900, one species of plant has been lost every two years on average on a county level.

According to the Intergovernmental Panel on Climate Change, biodiversity loss and degradation, and damages to and transformation of ecosystems are already key risks for every region of the world due to past global warming, and will continue to escalate with every increment of temperature. This crisis of nature is now being recognised alongside the climate crisis as a serious threat to the future of the people and other creatures living on the planet.

Part of our Christian discipleship, as we care for creation, is to notice what we’re interconnected with, so that we can wonder at God’s creation and then take action to safeguard it on this island we call home.

(Washington Post) ChatGPT took their jobs. Now they walk dogs and fix air conditioners.

Experts say that even advanced AI doesn’t match the writing skills of a human: It lacks personal voice and style, and it often churns out wrong, nonsensical or biased answers. But for many companies, the cost-cutting is worth a drop in quality.

“We’re really in a crisis point,” said Sarah T. Roberts, an associate professor at University of California in Los Angeles specializing in digital labor. “[AI] is coming for the jobs that were supposed to be automation-proof.”

AI and algorithms have been a part of the working world for decades. For years, consumer-product companies, grocery stores and warehouse logistics firms have used predictive algorithms and robots with AI-fueled vision systems to help make business decisions, automate some rote tasks and manage inventory. Industrial plants and factories have been dominated by robots for much of the 20th century, and countless office tasks have been replaced by software.

But the recent wave of generative artificial intelligence – which uses complex algorithms trained on billions of words and images from the open internet to produce text, images and audio – has the potential for a new stage of disruption. The technology’s ability to churn out human-sounding prose puts highly paid knowledge workers in the crosshairs for replacement, experts said.
