Engineers and scientists have an enduring fascination with spider silk. Similar to the typical silkworm silk from which comfortable sheets are made, but much stronger, the material inspired the invention of lighter, more breathable body armor and materials that could make aircraft components stronger without adding weight. Researchers are even using examples from spider webs to design sensitive microphones that may one day be used to treat hearing loss and deafness and to improve other listening devices.Spiders use their webs like huge external eardrums. A team of scientists from Binghamton University and Cornell University reported in 2022 that the webs allow the arachnids to detect sound from 10 feet away.When you hear a sound through your ear, what you're actually experiencing ar...

Russian forces continued to advance heavily into northeastern Ukraine on Saturday, closing in on a village about 10 miles from the Outer Ring of Kharkiv and raising fears that the city, Ukraine's second largest, could soon be in the range of Russian artillery.The Ukrainian army said Saturday that Russian troops attempted to break through its defenses near the village of Lyptsi, which lies directly north of Kharkiv. The attacks were repelled, but battlefield maps compiled by independent groups that analyzed publicly available videos of the fighting showed that Russian troops had almost reached the outskirts of the village.Ukraine's Khartia Brigade, which is defending Lyptsi, posted a video on Telegram on Friday afternoon in which Russian soldiers could be seen advancing on foot tow...

For the past year and a half since ChatGPT was released, a frightening question has hovered over the heads of major online publishers: what would happen if Google decided to overhaul its main search engine to give greater prominence to generative artificial intelligence – and in would it interrupt our business in the meantime? ?The question speaks to one of the most fragile dependencies in today's online media ecosystem.Most large publishers, including the New York Times, get a significant share of traffic from people who go to Google, search for something, and click on articles about it. That traffic, in turn, allows publishers to sell ads and subscriptions, which pay for the next wave of articles, which Google can then show to people searching for the next thing.The whole symbiotic...

At school tables and desks transformed into shelters, wartime vendors lined a street, selling used clothes, baby formula, canned food and the rare batch of homemade biscuits.In some cases, entire aid packages – still decorated with the flags of donor countries and intended to be distributed free of charge – were stacked on sidewalks and sold at prices few could afford.Issam Hamouda, 51, stood next to his meager commercial offering: an array of canned vegetables and beans from a relief carton his family received."Most goods found in markets carry the label 'Not for sale,'" he said.Before the war between Israel and Hamas devastated Gaza's economy, he was a driving instructor. Now, Mr. Hamouda supports his family of eight in the only way he can: by reselling some of the food aid ...

It takes a lot of energy to grow a baby – ask anyone who's been pregnant. But scientists are only now finding out how much.In a study published Thursday in the journal Science, Australian researchers estimated that a human pregnancy requires nearly 50,000 food calories over the course of nine months. That's the equivalent of about 50 pints of Ben and Jerry's Cherry Garcia ice cream, and much more than the researchers expected.Previous estimates were lower because scientists generally assumed that most of the energy involved in reproduction ends up stored in the fetus, which is relatively small.But Dustin Marshall, an evolutionary biologist at Monash University, and his students found that the energy stored in a baby's tissues represents only about 4% of the total energy c...

Joining the ranks of screen goddess Brigitte Bardot and the Eiffel Tower, another French treasure is being celebrated with its own stamp: the baguette.And that's scratch and sniff.The latest showcase of French cultural heritage as Paris prepares to host millions of visitors for the Summer Olympics and Paralympics, the new stamp features a cartoon image of a baguette wrapped in a tricolor ribbon.It was inaugurated by the French post office on Thursday 16 May, the feast day of Saint Honoré, patron saint of bakers.“The baguette, the bread of our daily life, the symbol of our gastronomy, the jewel of our culture,” praised the usually unobtrusive postal service in describing its new offering.The stamp, intended to be used for international letters weighing up to 20 grams, or about 0.7 ounce...

The two-story library has oriental rugs, shaded lamps dotting the desks, and rows of hardback books lining the walls. It is the architectural centerpiece of the offices of OpenAI, the start-up whose online chatbot, ChatGPT, showed the world that machines can instantly generate their own poetry and prose.The building, which was once a mayonnaise factory, looks like a typical tech office, with its communal work spaces, well-stocked micro-kitchens and private nap rooms spread across three floors in San Francisco's Mission District.But then there's that library, with the feel of a Victorian-era reading room. His shelves offer everything from Homer's "The Iliad" to David Deutsch's "The Beginning of Infinity," a favorite of OpenAI CEO Sam Altman.Built at Altman's request an...

Humanitarian aid trucks began disembarking in Gaza on Friday morning through a temporary pier built by the US military, the first aid supplies sent to the enclave by sea in two months. But the new shipments of food and other supplies fall far short of what aid groups say is needed to address the staggering levels of hunger and deprivation in Gaza.A day earlier, the US military said it had anchored the floating dock and causeway to the Gaza beach, a key step in completing the sea corridor announced by the Pentagon in March. U.S. officials and international aid groups have said sea shipments can only supplement deliveries through land passages, not replace them.No American troops entered Gaza on Friday, the US military said, stressing that it was only providing logistical support for the d...

When a patient with a severe traumatic brain injury is in a coma, in intensive care, unresponsive and on a ventilator, but not brain dead, when is it time to withdraw life support? A small study on the fate of people in such situations suggests that doctors and patients' families might make better decisions if they waited even a few days longer than usual.Often, a doctor meets with family members within 72 hours of the patient's admission to the ICU to discuss the patient's prognosis and whether they want to keep their loved one alive or remove life support.Experts say many doctors would describe the outlook as grim: most likely death or severe disability. Results reported on patients who have had severe traumatic brain injuries show that most of the time the decision is to r...
