Finding Power in My Panic Attacks
Trouble started in the form of rivulets of sweat dampening the waistband of my underwear. It was a bluebird afternoon in Phoenix in December of 2020, mid 60s, desert dry, and my heart was jackhammering against my ribcage. Breathing felt like I was sucking air through a stir straw. A small ABC News crew was arrayed before me, ready to broadcast the report I’d written that day, but with my vision narrowed to a needle’s eye, I could barely see them. I tried to swallow away the sandiness in my mouth but realized I’d forgotten how. [time-brightcove not-tgx=”true”] “I can’t swallow!...

Watch a person unable to speak for years ‘talk’ using a new brain implant
When it comes to talking, our brain does the heavy lifting. It subconsciously directs the complex coordination of lips, tongue, throat, and jaws we need to pronounce words. And it keeps directing, even in people with paralysis or who are unable to turn these commands into speech. Now, scientists have harnessed this phenomenon to create brain implants that transform this neural activity into text with unprecedented speed and accuracy. In two new studies—both reported today in Nature —the devices enabled two people to “speak” for the first time in more than a decade. The implants produced speech from brain...

These ants are ballooning with microbe-killing honey
Buried deep underneath the red, sunbaked soil of Australia’s deserts are hidden treasure troves of honey. It’s not the delicacy produced by bees, but rather the only type of honey made by ants. It’s also, a new study confirms, a potentially powerful medicine with antimicrobial properties. Australia’s Indigenous peoples have long used honey from honeypot ants ( Camponotus inflatus ) to treat a variety of maladies, from sore throats to infected wounds. Now, Western scientists are finally getting up to speed. In a study published today in PeerJ , researchers show that the honeypot ant’s honey has...

Can ‘toxic’ bilirubin treat a variety of illnesses?
Generations of medical and biology students have been instilled with a dim view of bilirubin. Spawned when the body trashes old red blood cells, the molecule is harmful refuse and a sign of illness. High blood levels cause jaundice, which turns the eyes and skin yellow and can signal liver trouble. Newborns can’t process the compound, and although high levels normally subside, a persistent surplus can cause brain damage. Yet later this year up to 40 healthy Australian volunteers may begin receiving infusions of the supposedly good-for-nothing molecule. They will be participating in a phase 1 safety trial, sponsored ...

Scientists use AI to decipher words and sentences from brain scans
A technique based on artificial intelligence (AI) can translate brain scans into words and sentences, a team of computational neuroscientists reports. Although in the early stages and far from perfect, the new technology might eventually help individuals with brain injuries or paralysis regain the ability to communicate, researchers say. The study “shows that, using the right methods and better models, we can actually decode what the subject is thinking,” says Martin Schrimpf, a computational neuroscientist at the Massachusetts Institute of Technology who was not involved in the work. Other research teams hav...

Straight from the heart: Mysterious lipids may predict cardiac problems better than cholesterol
Stephanie Blendermann, 65, had good reason to worry about heart disease. Three of her sisters died in their 40s or early 50s from heart attacks, and her father needed surgery to bypass clogged arteries. She also suffered from an autoimmune disorder that results in chronic inflammation and boosts the odds of developing cardiovascular illnesses. “I have an interesting medical chart,” says Blendermann, a real estate agent in Prior Lake, Minnesota. Yet Blendermann’s routine lab results weren’t alarming. At checkups, her low-density lipoprotein (LDL), or “bad,” cholesterol hovered around the 100 milligrams-per-...

How AI Is Changing Medical Imaging to Improve Patient Care
That doctors can peer into the human body without making a single incision once seemed like a miraculous concept. But medical imaging in radiology has come a long way, and the latest artificial intelligence (AI)-driven techniques are going much further: exploiting the massive computing abilities of AI and machine learning to mine body scans for differences that even the human eye can miss. Imaging in medicine now involves sophisticated ways of analyzing every data point to distinguish disease from health and signal from noise. If the first few decades of radiology were about refining the resolution of the pictures taken of...

Ditching cigarettes for smokeless tobacco can help cut cardiovascular risks, study finds
Regular smokers are at heightened risk of developing cardiovascular disease, but crushing the butts in favor of a “smokeless” alternative like chewing tobacco, snuff or tobacco lozenges may go a long way toward bringing the danger down to a more normal level, a new UCLA-led study shows.The findings also indicate that the primary culprit in smokers ’ increased risk is not nicotine but other chemicals found in tobacco smoke. Both cigarettes and smokeless tobacco products contain large quantities of nicotine.The study,published today in the journal Nicotine and Tobacco Research, involved a team of researchers from UCLA...

Bringing WISDOM to Breast Cancer Care
Dr. Laura Esserman answers the door of her bright yellow Victorian home in San Francisco’s Ashbury neighborhood with a phone at her ear. She’s wrapping up one of several meetings that day with her research team at University of California, San Francisco, where she heads the Carol Franc Buck Breast Care Center. She motions me in and reseats herself at a makeshift home office desk in her living room, sandwiched between a grand piano and set of enormous windows overlooking her front yard’s flower garden. It’s her remote base of operations when she’s not seeing patients or operating at the hospita...
