1 . The world’s largest ape Gigantopithecus blacki (G. blacki) vanished from Earth between 295, 000 and 215, 000 years ago, more than 100, 000 years earlier than once thought, pushed to extinction as the environment around it shifted, researchers reported recently in Nature.
The fate of G. blacki, twice the size of the largest modern apes and resembling a super-sized version of its close cousin, the orangutan, has long been a mystery. For about 2 million years, G. blacki inhabited a landscape of forests and grasses in what’s now southern China. It left behind only scattered remnants: thousands of teeth and four jawbones, unearthed in cave sediments in the region.
To establish a chronology for the ape’s extinction, paleoanthropologist Yingqi Zhang of the Chinese Academy of Sciences in Beijing and his colleagues used different dating techniques to determine the ape’s habits, diet and environment. In the teeth, they looked for data on the ape’s diet, measuring isotopes (同位素) of carbon and oxygen as well as examining the teeth for tiny evidence of wear and tear — which can reveal not only diet, but also give hints of repeated behaviors and stress. The team also analyzed the cave sediments bearing the fossils, hunting for fossil pollen and conducting luminescence dating (光释光测年) on radioactive elements within the sediments.
The team’s reconstruction revealed that — around 700, 000 to 600, 000 years ago, southern China shifted from its forested landscape to a more seasonally-driven environment. Some apes, including the orangutans, were able to adapt to these changes. But G. blacki was unable to change rapidly enough, and its numbers slowly dwindled before going extinct, the team suggested.
The assembled evidence told a convincing story that “the extinction of G. blacki coincided in southern China with a decrease of forest cover and expansion of savanna-like environments,” said Hervé Bocherens, a biogeologist at the University of Tuebingen in Germany. Still, he said, documenting the extinction of this species from the fossil record is tricky — and it’s impossible to rule out the possibility that pockets of G. blacki may have lingered in still-undiscovered caves for longer.

3 . Beejhy Barhany, growing up in an Ethiopian-Jewish community in Israel, has been cooking for her family as long as she can remember. Now a chef and owner of Tsion Café in Harlem, New York, Barhany continues to pull from cooking traditions, including one that has become the source of much controversy in recent decades: washing raw meat before cooking.
For Barhany, submerging raw chicken in salt and lemon water is both functional and ceremonial, as soaking or rinsing raw meat in salt water and acid-such as lemon juice or vinegar-is a common form of “washing” required by Jewish Kosher rules. And a 2015 survey of over 1, 500 American consumers found that nearly 70 percent rinse or wash their poultry before cooking it, though the U. S. Department of Agriculture( USDA) started telling consumers not to wash raw poultry in the 1990s. Experts including those from the Centers for Disease Control and Prevention strongly warned that rather than reducing the risk of foodborne illness (食源性疾病), washing meat increases the likelihood of spreading unwanted pathogens (病原体), like salmonella and campylobacter, around the kitchen.
“Washing meat before cooking is not really helping,” says Betty Feng, associate professor of food science at Purdue University. “The only thing it does is splashing (飞溅) and could cross-contaminate a lot of your kitchen items-your sink, probably your clothes, whatever you have by the sink.” Moreover, Feng cautions against using saltwater, vinegar, or lemon juice, which simply isn’t strong enough to effectively kill foodborne pathogens. “If the acidity is high enough to kill bacteria, then it’s not really likely you can use your bare hand to wash,” she says.
And a 2022 study showed that submerging meat in a bowl of water reduced the splashing but not the spread of germs. “I would treat the entire sink just like the outside of the chicken——it’s a biological hazard,” says Benjamin Chapman, one of the study authors and associate professor in North Carolina State University’s agricultural and human sciences department. “The way that we make meat safe is through cooking, not through the removal of pathogens.”

5 . The innovation is part of research into brain-computer interfaces (接口) to help improve the lives of people with motor disabilities. The researchers included machine learning capabilities with their brain-computer interface, making it a one-size-fits-all solution.
Typically, these devices require extensive adjustment for each user- every brain is different, both for healthy and disabled users- and that has been a major hurdle to mainstream adoption. This new solution can quickly understand the needs of an individual subject and self-adjust through repetition. That means multiple patients could use the device without needing to tune it to the individual.
In a clinical setting, the subjects wear a cap packed with electrodes (电极) that is connected to a computer. The electrodes gather data by measuring electrical signals from the brain, and the decoder translates the brain signals into commands, which are used to control devices or applications. In this case, the decoded signals are translated into actions in a car racing game and a simpler task involving balancing a digital bar. Subjects were trained simultaneously for both the simpler bar game and the more complex car racing game, thus improving their brain function.
The researchers call this work foundational, in that it sets the stage for further brain-computer interface innovation. This project used 18 subjects with no motor disabilities. As they continue down this road, they will test this on people with motor disabilities to apply it to larger groups in clinical settings. “To achieve this, we need to improve our technology to make it easier to use,’ Millan. a professor in the University of Texas says.
On the side of translating the research, Millan and his team continue to work on a wheelchair that users can drive with the brain- computer interface. At the South by Southwest Conference and Festivals this month, the researchers showed off another potential use of the technology. controlling two rehabilitation (康复) robots for the hand and arm. This was not part of the new paper but a sign of where this technology could go in the future. “We’ll continue down this path wherever it takes us in the pursuit of helping people.” Millan says.

8 . Zong Qinghou, the rags-to-riches founder of one of China’s biggest beverage makers, who was once China’s richest man, died of an illness on Sunday at the age of 79, his company Hangzhou Wahaha Group said in a brief statement.
In China, Zong was known as a legendary businessman who grew his soft drinks empire from a tricycle cart hawking (沿街叫卖) ice pops to school kids into a large company selling everything from milk drinks to bottled water and canned porridge.
Zong was also recognized as a national hero for wrestling the full control of Wahaha, which means “laughing child”, from its French partner Danone more than a decade ago. Victory in that bitter battle boosted Zong’s wealth to $8 billion, making him China’s richest man in 2010 and again in 2012, according to Forbes.
His death was mourned across China. Condolences (吊唁) poured in from remarkable Chinese entrepreneurs including Alibaba co-founder Jack Ma and Xiaomi CEO Lei Jun. Wahaha employees and residents in the eastern city of Hangzhou laid flowers outside the company.
The beverage giant’s rise came to represent the can-do spirit of China’s first generation of private entrepreneurs, who helped accelerate the country’s explosive economic growth in the years after they capitalized on market reforms in the late 1970s.
Despite his wealth, Zong was known for his simple lifestyle, which set him apart from many of China’s new rich. He was nicknamed “the richest man in cloth shoes” for always sporting plain black shoes.
In an interview with the state-run People’s Daily in 2010, Zong said the title and wealth had brought little change to his life. “Every day, I still smoke two packs of cigarettes that cost 12 yuan (then $1.80) each, have two cups of tea, and eat my three meals at the company canteen,” he said. He was known for starting work around 7 am and not leaving the office until 11 pm, working for more than 12 hours a day long before the tiring “996” work schedule became common.

9 . A new color-changing ink could aid in health and environment monitoring — for example, allowing clothing that switches colors when exposed to sweat or a curtain that shifts colors if carbon monoxide (一氧化碳) enters a room. The chemicals could be printed on anything from a T-shirt to a tent.
Wearable sensing devices like smart watches use electronics to monitor heart rate, blood glucose (血糖), and more. Now researchers at Tufts University’s Silklab say their new silk-based inks can respond to the presence of chemicals on or around the body.
The researchers had created an earlier version of the material that inkjet printers could spray on fabric, turning small items, such as gloves, into sensors. For the recent study, published online in May in Advanced Materials, they thickened the ink with certain chemicals and then added various reactive substances. With the new ink, they can now “easily print a large number of reactive elements onto large surfaces,” says Fiorenzo Omenetto, a biomedical engineer at Silklab.
“In the case of a T-shirt, the wearer ‘paints’ the shirt through exercise — with colors correlating to the acidity distribution of their sweat,” Omenetto says. He envisions using the ink to help monitor such activity. It could also be adapted to track environmental changes in a room, he says — or to respond to bacteria and follow disease progression.
Mechanical engineer Tyler Ray of the University of Hawaii at Manoa, who was not involved with the study, notes that most of today’s wearable monitors are rigid, wired and relatively large and heavy. The new in k technology has “the potential to transform consumer wearables from recreational novelty devices into body-worn, clinical-grade physiological measurement tools that supply physician-actionable information,” he says. But “one of the challenges with any colorimetric (比色的) approach is the effect various environmental conditions have on accuracy, such as lighting or the camera used.” Future studies would need to address these issues.
