Experimental brain-controlled hearing aid decodes, identifies who you want to hear
Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing aids struggle to do. But now Columbia engineers are announcing an experimental technology that mimics the brain's natural aptitude for detecting and amplifying any one voice from many. Powered by artificial intelligence, this brain-controlled hearing aid acts as an automatic filter, monitoring wearers' brain waves and boosting the voice they want to focus on.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

'Foldable' PC? Lenovo ThinkPad laptop screen bends in half like a book
Samsung has gained a lot attention lately for its Galaxy Fold hybrid smartphone/tablet, though given the recent display snags that have prompted a delay in the product's release, not necessarily for all the right reasons.

What's causing your vertigo? Goggles may help with diagnosis
Vertigo is a form of severe dizziness that can result in a loss of balance, a feeling of falling, trouble walking or standing, or nausea. There is more than one type of vertigo, each with a different cause, and sometimes requiring different treatment. Now a proof-of-concept study has found that special goggles that measure eye movements during an episode of vertigo may help more accurately diagnose which type of vertigo a person has. The study is published in the May 15, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.

Once-per-month HIV drugs on the horizon
An HIV diagnosis was once a death sentence, but now people who receive treatment survive for decades with the disease. Keeping the virus at bay usually requires taking a pill every day, which aside from being inconvenient for some, is an unwelcome daily reminder of the disease. That's why drug companies are developing longer-acting, injectable HIV treatments, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

Cellular rivalry promotes healthy skin development
Not all cells are destined for greatness. Deemed unfit to serve in the body, some are killed off during early development through a process called cell competition. This phenomenon has previously been documented in flies and is now turning out to occur in mammals as well.

Coherent? Voice disorders significantly affect listeners, too
"Fly heading two three zero, runway two seven left, cleared for takeoff." Air traffic controllers are among the 25 to 45 percent of the workforce in the United States who use their voices professionally. It is imperative for their listeners to understand what they are communicating. Air traffic controllers, teachers and university professors have a high prevalence of voice disorders referred to as "dysphonia." Other professions also are at risk including clergy, attorneys, counselors and performers.

New strategy of reprogramming regulatory T cells may improve cancer therapies
While therapies that harness the power of the immune system against cancer have made remarkable progress against certain types of tumors, they still remain ineffective in most cancer patients. A new study from the Center for Immunology and Inflammatory Diseases (CIID) at Massachusetts General Hospital (MGH) describes a method of reprogramming the regulatory T cells that usually suppress immune responses into inflammatory cells that not only permit but also intensify an antitumor immune response. Their paper is receiving advance online release in Nature.
