A set of 10 articles identified by Dr. David showed repeated reuse of identical or overlapping black-and-white images of cancer cells supposedly under different experimental conditions, he said.”There’s no reason to have done that unless you didn’t do the job,” Dr. David said.One of these documents, published in 2012, was officially marked with corrections. Unlike later studies, which were largely imposed by Dr. Yoon in New York, this paper was written by scientists based in South Korea, including Changhwan Yoon, who then worked in Seoul.An immunologist in Norway randomly selected the paper as part of a review of duplicated data…

As the helicopter ascended into the sky, my heart raced with excitement and a twinge of fear: This was my first helicopter ride. The man next to me glanced over and asked why I would choose to visit the Gurez Valley now, when it had so little to offer. “Even the locals avoid it if they can,” he said.I didn’t have a clear answer. All I knew was that the Himalayan valley, shrouded in snow and the secrets in the far reaches of Indian-controlled Kashmir, held something important for me, and I was willing to brave the dangers of winter…

Defense Secretary Lloyd J. Austin III, speaking via video, told defense ministers gathered in Brussels on Wednesday that the United States would maintain its support for Ukraine, but made no mention of a multibillion-dollar aid package it has not received yet congressional approval.Mr Austin delivered his comments in a five-minute speech via video link to a meeting of about 50 countries from the US-led Ukraine Defense Contact Group, which directs military aid to the country.”We will continue to dig deep to provide Ukraine with both short-term and long-term support,” said Mr. Austin, who canceled his trip to Brussels because of…

For many progressives, it was a big moment. In 2019, Congress held its first hearing on whether the United States should pay reparations for slavery.To support the idea, Democrats called on influential author Ta-Nehisi Coates, who had revived the reparations issue in an op-ed in The Atlantic, and actor and activist Danny Glover.Republicans turned to a virtual unknown: a 23-year-old philosophy professor at Columbia University, Coleman Hughes.At the hearing, Mr. Hughes, looking very much his age, testified to a House subcommittee that the failure to pay reparations after the Civil War was “one of the greatest injustices ever committed.”But, he…

Another month, another attempt at the moon.A robotic lunar rover launched into space early Thursday morning. If all goes well, in nine days, it will become the first U.S. spacecraft to gently touch down on the surface of the Moon since Apollo 17 landed in 1972.It would also be the first private attempt to reach the surface of the moon in one piece. Three previous attempts, by an American company, a Japanese company and an Israeli non-profit, failed.The company tasked with this mission, Intuitive Machines of Houston, is optimistic.”I feel pretty confident that we’re going to be successful when we…

Elon Musk, the CEO and public face of Tesla, is constantly making news and airing his views on the social networking site X. But the electric car company has another leader — one who keeps a much lower profile.For more than five years, Tesla’s board of directors has been led by Robyn M. Denholm, a tech executive who rarely speaks publicly outside her native Australia and publishes almost nothing on X.For some analysts and investors, Ms. Denholm is the “adult in the room” who helped Mr. Musk turn Tesla into the world’s most valuable automaker. But to her critics, she…

The Federal Trade Commission and the Department of Health and Human Services said Wednesday they will look into the causes of generic drug shortages and the practices of “powerful middlemen” involved in the supply chain.The federal agency investigation is targeting syndicates and drug distributors that have come under fire in recent months as drug shortages have reached a 10-year high. The agencies want to examine the companies’ influence on how the drugs are sold to hospitals and other health facilities, assessing whether middlemen exerted pressure on pricing and manufacturing that led to harm.During congressional hearings last year, oncology experts testified…

Like the allure of vinyl records, classic video games, and even the early Internet, the fascination with older photography standards like point-and-shoot cameras or 35mm film persists — even to people too young to remember when this equipment was cutting edge. The appeal of vintage photography goes beyond nostalgia and Instagram filters, judging by the sheer number of apps designed to mimic the film, lenses and visual quirks of vintage photos and movies.Despite the irony of using a high-end smartphone camera to produce imperfect images that look oversaturated, jittery, low-contrast, unfiltered, or otherwise analog, the retro look can help you…

Hundreds of displaced Palestinians were leaving a major hospital in the Gaza Strip on Wednesday, according to doctors and video footage from the scene, after Israeli forces ordered them to leave and threatened military action to stop Hamas activity at the hospital.Thousands of Gazans have been taking refuge at the Nasser Medical Complex in Khan Younis for weeks, forced from their homes and other parts of Gaza by Israel’s intense shelling of the ground and military orders to leave their towns and cities. Hospitals have become shelters during the war, even though they have often been the focus of Israel’s…
