Today would have been the 99th birthday of Ms. Henrietta Lacks, a woman whose remarkable DNA led to countless cures, patents and discoveries:
But critics point out that all that promise could vanish if the rush to implement A.I. tramples patient privacy rights, overlooks biases and limitations, or fails to deploy services in a way that improves health outcomes for most people.
You could be forgiven for thinking that A.I. will soon replace human physicians based on headlines such as “The A.I. Doctor Will See You Now,” “Your Future Doctor May Not Be Human,” and “This A.I. Just Beat Human Doctors on a Clinical Exam.” But experts say the reality is more of a collaboration than an ousting: Patients could soon find their lives partly in the hands of A.I. services working alongside human clinicians.

Голливудские звезды Арнольд Шварценеггер, Сильвестр Сталлоне и Дольф Лунгрен сообщили, что не собираются стареть.
На видео, опубликованном в “Инстаграме”, три звезды блокбастеров заявили, что они “мужчины, которые не собираются стареть”.

Researchers examining the brains of 324 men and women with a special form of magnetic resonance imaging called diffusion tensor imaging have identified interesting differences in the wiring of general knowledge buffs’ brains.
“Something happened to them. These findings of the inner ear disorder cannot be faked,” he said. “It is not hysteria. It is not crickets.”
Could a dog’s brain offer any clues to the mysterious concussion-like syndrome affecting Canadian and American diplomats who were posted to Cuba?
That is one of the many threads being pulled in an effort by researchers and scientists — and those affected — to better understand the condition referred to as Havana Syndrome, which has been blamed for debilitating some Canadian diplomats and their families.
In 1948, physicist Leonard Eisenbud proposed a particular way of transmitting the waves to overcome this. But not until now have researchers made it happen.
By Michael Slezak.
It’s a call with no response. A new way of creating waves – whether of light, radio or sound – that don’t echo promises to improve everything from your Wi-Fi signal to medical imaging to shining lasers through space.

Some call it a SASER and others call it a PHASER.
How do you whisper to someone across the room? With lasers, of course. MIT has developed a system using lasers to transmit audio signals directly to the ear, and no one else in the area can hear them. As a nice bonus, the laser won’t burn your skin or eyes should you turn your head at the wrong moment.
The laser system leverages what is known as the photoacoustic effect. That simply means that the absorption of light waves by a material produces sound waves. In this case, the light is absorbed by water molecules in the air, but the researchers learned to very carefully tune the laser to control where the sound appears. It’s essentially a narrow cone of sound.

Three newly discovered worlds are among the smallest and nearest we’ve ever detected.
NASA’s Transiting Exoplanet Survey Satellite, or TESS — a super-powerful orbiting telescope designed to hunt for alien worlds — found the planets orbiting a star just 73 light-years away.
One is a rocky “super-Earth” that’s more massive than our home planet but lighter than giants like Neptune. The other two are icy “sub-Neptunes” that are about half the size of Neptune.
A small, portable breath monitor can quickly and accurately detect acute respiratory distress syndrome, researchers report.
Acute respiratory distress syndrome (ARDS) is an often deadly disease that causes fluid to leak into the lungs and demands early diagnosis.
To detect the condition today, doctors rely heavily on their own judgment and time-consuming tests. The researchers say their new technology could improve survival rates and lower the cost of care.
