Elon Musk subpoenaed Jack Dorsey, co-founder of Twitter Inc. and his longtime friend, in his defense against the social media company’s lawsuit to make him complete his proposed $44 billion buyout.
Whether NASA likes it or not, humans eventually will be having space sex. This will pose many challenges, from cleanliness to pregnancy.
A biotech firm wants to create “synthetic” human embryos that would be used to harvest organs in order to facilitate transplants and treat conditions such as infertility, genetic disease, and aging, according to researchers.
The Israel-based company, Renewal Bio, claimed that it successfully used advanced stem cell technology and artificial wombs in order to grow mouse embryos which continued to develop for several days.

Headlines such as “MACHINE COMES TO LIFE” and “GOOGLE ENGINEER URGENT WARNING” have led many to believe that science fiction has become reality, with artificial intelligence reaching the level of human consciousness. What are the religious implications? And what are the facts? What do we know about how artificial intelligence really operates?
A report by the New York Times details two parents who say photos intended to help diagnose infections in their children were flagged by AI as potential CSAM. Their accounts were locked, and the police were alerted.
We all age. But the process of aging may be different in the year 2050 thanks to advances in medical tech.
In a significant development, Massachusetts Institute of Technology (MIT) engineers have developed a new category of wireless wearable skin-like sensors for health monitoring that doesn’t require batteries or an internal processor.
The team’s sensor design is a form of electronic skin, or “e-skin” — a flexible, semiconducting film that conforms to the skin like electronic Scotch tape, according to a press release published by MIT.
“If there is any change in the pulse, or chemicals in sweat, or even ultraviolet exposure to skin, all of this activity can change the pattern of surface acoustic waves on the gallium nitride film,” said Yeongin Kim, study’s first author, and a former MIT postdoc scholar.
In 1,885, King Oscar II of Sweden announced a public challenge consisting of four mathematical problems. The French polymath Henri Poincaré focused on one related to the motion of celestial bodies, the so-called n-body problem. Will our solar system continue its clocklike motion indefinitely, will the planets fly off into the void, or will they collapse into a fiery solar death?
Poincaré’s solution — which indicated that at least some systems, like the sun, Earth and moon, were stable — won the prestigious prize, and an accompanying article was printed for distribution in 1889. Unfortunately, his solution was incorrect.
Poincaré admitted his error and paid to have the copies of his solution destroyed (which cost more than the prize money). A month later, he submitted a corrected version. He now saw that even a system with only three bodies could behave too unpredictably — too chaotically — to be modeled. So began the field of dynamical systems.
Taste matters to fruit flies, just as it does to humans: like people, the flies tend to seek out and consume sweet-tasting foods and reject foods that taste bitter. However, little is known about how sweet and bitter tastes are represented by the brain circuits that link sensation to behavior.
In a new study published in Current Biology, researchers at Brown University described how they developed a new imaging technique and used it to map the neural activity of fruit flies in response to sweet and bitter tastes.
“These results show that the way fly brains encode the taste of food is more complex than we had anticipated,” said study author Nathaniel Snell, who earned his Ph.D. in neuroscience from Brown in 2021 and conducted the research as part of his thesis.
