      Can Xerox’s PARC, a Silicon Valley Icon, Find New Life with SRI?

      by

      Two research labs known for some of the tech industry’s most important innovations have merged in hopes of recapturing their glory days. It is one of Silicon Valley’s enduring legends. In 1979, a 24-year old Steve Jobs was permitted to visit Xerox’s Palo Alto Research Center (PARC) to view a demonstration of an experimental personal computer called the Alto. Mr. Jobs took away a handful of ideas that would transform the computing world when they became the heart of Apple’s Lisa and Macintosh computers. More

      ‘Dune’-like Sandworm Existed Millions of Years Longer Than Thought

      by

      Researchers examined fossils of the predatory worm and found a new species that persisted for 25 million years after it was believed to have become extinct.With a head covered in rows of curved spines, ancient Selkirkia worms could easily be confused with the razor-toothed sandworms that inhabit the deserts of Arrakis in “Dune: Part Two.”During the Cambrian Explosion more than 500 million years ago, these weird worms — which lived inside long, cone-shaped tubes — were some of the most common predators on the seafloor.“If you were a small invertebrate coming across them, it would have been your worst nightmare,” said Karma Nanglu, a paleontologist at Harvard. “It’s like being engulfed by a conveyor belt of fangs and teeth.”Thankfully for would-be spice harvesters, these ravenous worms disappeared hundreds of million years ago. But a trove of recently analyzed fossils from Morocco reveals that these formidable predators measuring only an inch or two in length, persisted much longer than previously thought.In a paper published today in the journal Biology Letters, Dr. Nanglu’s team described a new species of Selkirkia worm that lived 25 million years after this group of tube-dwellers was thought to have gone extinct.The newly described tubular worms were discovered when Dr. Nanglu and his colleagues sifted through fossils stored in the collection of Harvard’s Museum of Comparative Zoology. The fossils hail from Morocco’s Fezouata Formation, a deposit dating back to the Early Ordovician period, which began around 488 million years ago and spanned nearly 45 million years. This was a dynamic era when holdovers from the Cambrian rubbed shoulders with evolutionary newcomers like sea scorpions and horseshoe crabs.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Use of Abortion Pills Has Risen Significantly Post Roe, Research Shows

      by

      The NewsOn the eve of oral arguments in a Supreme Court case that could affect future access to abortion pills, new research shows the fast-growing use of medication abortion nationally and the many ways women have obtained access to the method since Roe v. Wade was overturned in June 2022.The DetailsPackages of abortion pills being prepared to send to patients.Sophie Park for The New York TimesA study, published on Monday in the medical journal JAMA, found that the number of abortions using pills obtained outside the formal health system soared in the six months after the national right to abortion was overturned. Another report, published last week by the Guttmacher Institute, a research organization that supports abortion rights, found that medication abortions now account for nearly two-thirds of all abortions provided by the country’s formal health system, which includes clinics and telemedicine abortion services.The JAMA study evaluated data from overseas telemedicine organizations, online vendors and networks of community volunteers that generally obtain pills from outside the United States. Before Roe was overturned, these avenues provided abortion pills to about 1,400 women per month, but in the six months afterward, the average jumped to 5,900 per month, the study reported.Overall, the study found that while abortions in the formal health care system declined by about 32,000 from July through December 2022, much of that decline was offset by about 26,000 medication abortions from pills provided by sources outside the formal health system.“We see what we see elsewhere in the world in the U.S. — that when anti-abortion laws go into effect, oftentimes outside of the formal health care setting is where people look, and the locus of care gets shifted,” said Dr. Abigail Aiken, who is an associate professor at the University of Texas at Austin and the lead author of the JAMA study. The co-authors were a statistics professor at the university; the founder of Aid Access, a Europe-based organization that helped pioneer telemedicine abortion in the United States; and a leader of Plan C, an organization that provides consumers with information about medication abortion. Before publication, the study went through the rigorous peer review process required by a major medical journal.The telemedicine organizations in the study evaluated prospective patients using written medical questionnaires, issued prescriptions from doctors who were typically in Europe and had pills shipped from pharmacies in India, generally charging about $100. Community networks typically asked for some information about the pregnancy and either delivered or mailed pills with detailed instructions, often for free.Online vendors, which supplied a small percentage of the pills in the study and charged between $39 and $470, generally did not ask for women’s medical history and shipped the pills with the least detailed instructions. Vendors in the study were vetted by Plan C and found to be providing genuine abortion pills, Dr. Aiken said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      The Psychedelic Evangelist

      by

      Before he died last year, Roland Griffiths was arguably the world’s most famous psychedelics researcher. Since 2006, his work has suggested that psilocybin, found in magic mushrooms, can induce mystical experiences, and that those experiences, in turn, can help treat anxiety, depression, addiction and the terror of death.Dr. Griffiths and his colleagues at Johns Hopkins University received widespread recognition among scientists and the popular press, helping to pull the psychedelic field from the deep backwater of the 1960s hippie movement. This second wave of research on the hallucinogenic compounds bolstered political campaigns to decriminalize them and spurred biotech investment.Dr. Griffiths was known to friends and colleagues as an analytical thinker and a religious agnostic, and he warned fellow researchers against hype. But he also saw psychedelics as more than mere medicines: Understanding them could be “critical to the survival of the human species,” he said in one talk. Late in life, he admitted to taking psychedelics himself, and said he wanted science to help unlock their transformative power for humanity.Perhaps unsurprisingly, he held a vaunted, even prophetic role among psychonauts, the growing community of psychedelic believers who want to bring the drugs into mainstream society. For years, critics have denounced the outsize financial and philosophical influence of these advocates on the insular research field. And some researchers have quietly questioned whether Dr. Griffiths, in his focus on the mystical realm, made some of the same mistakes that doomed the previous era of psychedelic science.Now, one of his longtime collaborators is airing a more forceful critique. “Dr. Griffiths has run his psychedelic studies more like a ‘new-age’ retreat center, for lack of a better term, than a clinical research laboratory,” reads an ethics complaint filed to Johns Hopkins last fall by Matthew Johnson, who worked with Dr. Griffiths for nearly 20 years but resigned after a charged dispute with colleagues.Roland Griffiths, director of the Center for Psychedelic and Consciousness Research at Johns Hopkins, in 2021.Matt Roth for The New York TimesWe are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Total Solar Eclipse Safety: How to Watch Without Hurting Your Eyes

      by

      A number of case studies published after recent total solar eclipses highlight the importance of safe viewing.A young woman visited New York Eye & Ear Infirmary of Mount Sinai Hospital shortly after the eclipse of Aug. 21, 2017. She told Dr. Avnish Deobhakta, an ophthalmologist, that she had a black area in her vision, and then drew a crescent shape for him on a piece of paper.When Dr. Deobhakta examined her eyes, he was astonished. He saw a burn on her retina that was exactly the same shape. It was “almost like a branding,” he said.She had looked at the sun during the eclipse without any protection. The burn was an image of the sun’s corona, its halo-like outer rim.With every eclipse, ophthalmologists see patients who looked at the sun and complain afterward that their vision is distorted: They see small black spots, their eyes are watery and sensitive to light. Usually, the symptoms resolve, although it may take several weeks to a year.But the woman’s retinal burns, which Dr. Deobhakta and colleagues described in a medical case write-up, would not heal. Her retina was permanently scarred and a sign of the severity of injuries that can follow looking at an eclipse without proper precautions.With the coming eclipse in April, ophthalmologists advise people to be careful and not assume that short glances at the sun are safe. Damage can occur, they say, in less than a minute.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Yale Apologizes for Its Connections to Slavery

      by

      The university also issued a historical study and announced steps to address this legacy, including new support for public education in New Haven, Conn.Yale University on Friday issued a formal apology for its early leaders’ involvement with slavery, accompanied by the release of a detailed history of the university’s connections to slavery and a list of what it said were initial steps to make some amends.The announcement came more than three years after Yale announced a major investigation into the university’s connections to slavery, the slave trade and abolition, amid intense national conversations about racial justice set off by the murder of George Floyd. And it frames what the school’s leaders say will be a continuing commitment to repair.“We recognize our university’s historical role in and associations with slavery, as well as the labor, the experiences and the contributions of enslaved people to our university’s history, and we apologize for the ways that Yale’s leaders, over the course of our early history, participated in slavery,” the university’s president, Peter Salovey, and the senior board trustee, Josh Bekenstein, said in a message to the university community.“Acknowledging and apologizing for this history are only part of the path forward,” they continued. The university is also creating new programs to fund the training of public schoolteachers for its home city, New Haven, Conn., whose population is predominantly Black. And Yale will expand previously announced research partnerships with historically Black colleges and universities across the country, with a “significant new investment” to be announced in coming weeks.Unlike Harvard, which in 2022 committed $100 million to a “Legacy of Slavery Fund,” Yale did not announce an amount for all its initiatives.David W. Blight, the Yale historian who led the historical research, said in an interview that the purpose of the effort was not “to cast ugly stones at anybody,” but to present the university’s history honestly and unflinchingly.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Chinese Influence Campaign Pushes Disunity Before U.S. Election, Study Says

      by

      A long-running network of accounts, known as Spamouflage, is using A.I.-generated images to amplify negative narratives involving the presidential race.A Chinese influence campaign that has tried for years to boost Beijing’s interests is now using artificial intelligence and a network of social media accounts to amplify American discontent and division ahead of the U.S. presidential election, according to a new report.The campaign, known as Spamouflage, hopes to breed disenchantment among voters by maligning the United States as rife with urban decay, homelessness, fentanyl abuse, gun violence and crumbling infrastructure, according to the report, which was published on Thursday by the Institute for Strategic Dialogue, a nonprofit research organization in London.An added aim, the report said, is to convince international audiences that the United States is in a state of chaos.Artificially generated images, some of them also edited with tools like Photoshop, have pushed the idea that the November vote will damage and potentially destroy the country.One post on X that said “American partisan divisions” had an image showing President Biden and former President Donald J. Trump aggressively crossing fiery spears under this text: “INFIGHTING INTENSIFIES.” Other images featured the two men facing off, cracks in the White House or the Statue of Liberty, and terminology like “CIVIL WAR,” “INTERNAL STRIFE” and “THE COLLAPSE OF AMERICAN DEMOCRACY.”The campaign’s artificially generated images, some of them also edited with tools like Photoshop, have pushed the idea that the November vote will damage and potentially destroy America.via XWe are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
