Breast changes are very common, and most breast changes are not cancer. Our health guide for women explains:
A breast lump may be benign or a symptom of breast cancer. Learn about follow-up after an abnormal mammogram. See pictures of breast cancer, cysts, and calcifications. Find out symptoms for benign breast conditions, precancers, and DCIS.
A large team of computer scientists and engineers at IBM Research has developed a dedicated computer chip that is able to run AI-based image recognition apps 22 times as fast as chips that are currently on the market.
In their paper published in the journal Science, the group describes the ideas that went into developing the chip, how it works and how well it performed when tested. Subramanian Iyer and Vwani Roychowdhury, both at the University of California, Los Angeles, have published a Perspective piece in the same journal issue, giving an in-depth analysis of the work by the team in California.
As AI-powered applications become mainstream tools used by professionals and amateurs alike, scientists continue work to make them better. One way to do that, Iyer and Roychowdhury note, is to move toward an “edge” computer system in which the data is physically closer to the AI applications that are using them.

It’s been a month since a Maryland man became the second person to receive a transplanted heart from a pig — and hospital video released Friday shows he’s working hard to recover.
Lawrence Faucette was dying from heart failure and ineligible for a traditional heart transplant when doctors at the University of Maryland School of Medicine offered the highly experimental surgery.
In the first glimpse of Faucette provided since the Sept. 20 transplant, hospital video shows physical therapist Chris Wells urging him to push through a pedaling exercise to regain his strength.
Researchers have developed a potentially revolutionary superlens technique that once seemed impossible to see things four times smaller than even the most modern microscopes have seen before. Known as the ‘diffraction limit’ because the diffraction of light waves at the tiniest levels has prevented microscopes from seeing things smaller than those waves, this barrier once seemed unbreakable.
Many have tried to peer below this optical barrier using a technique that researchers in the field term ‘superlensing, including making customized lenses out of novel materials. But all have gathered too much light. Now, a team of physicists from the University of Sydney says they have discovered a viable path that peeks beyond the diffraction limit by a factor of four times, allowing researchers to see things smaller than ever seen before. And the way they did, it is like nothing anyone else has tried.
Breaking the Diffraction Limit by ‘Superlensing’ without a Superlens.
Unfortunately, these precise cell arrangements are also why artificial muscles are difficult to recreate in the lab. Despite being soft, squishy, and easily damaged, our muscles can perform incredible feats—adapt to heavy loads, sense the outside world, and rebuild after injury. A main reason for these superpowers is alignment—that is, how muscle cells orient to form stretchy fibers.
Now, a new study suggests that the solution to growing better lab-grown muscles may be magnets. Led by Dr. Ritu Raman at the Massachusetts Institute of Technology (MIT), scientists developed a magnetic hydrogel “sandwich” that controls muscle cell orientation in a lab dish. By changing the position of the magnets, the muscle cells aligned into fibers that contracted in synchrony as if they were inside a body.
The whole endeavor sounds rather Frankenstein. But lab-grown tissues could one day be grafted into people with heavily damaged muscles—either from inherited diseases or traumatic injuries—and restore their ability to navigate the world freely. Synthetic muscles could also coat robots, providing them with human-like senses, flexible motor control, and the ability to heal after inevitable scratches and scrapes.

Scientists at Kyushu University report that turning brain immune cells into neurons restores brain function after stroke-like injury in mice. Their findings suggest that replenishing neurons from immune cells could be a potential avenue for treating stroke in humans.
The findings are published in PNAS in an article titled, “Direct neuronal conversion of microglia/macrophages reinstates neurological function after stroke.”
“Although generating new neurons in the ischemic injured brain would be an ideal approach to replenish the lost neurons for repairing the damage, the adult mammalian brain retains only limited neurogenic capability,” wrote the scientists. “Here, we show that direct conversion of microglia/macrophages into neurons in the brain has great potential as a therapeutic strategy for ischemic brain injury.”
The company has also introduced a new robotic system called Sequoia to assist employees in fulfilling consumer requests, which is applied to one of its fulfillment centers in Houston, Texas.
