A new light-trapping sensor makes infrared absorption more sensitive, inexpensive and versatile. It may improve scientists’ ability use to sleuth out performance-enhancing drugs in blood samples, tiny particles of explosives in the air and more.
20 years ago, RENT was a hit Broadway musical, Angels in America was required reading in many English Lit classes, and Philadelphia was a Blockbuster Video must-see. But though AIDS continues to be a global health crisis worldwide (including right here in America), the disease has largely retreated from pop culture plot points… and become less visible to Millennials and Gen Z.

Enter Rose McGowan, bombshell actress turned humanist activist, whose latest project seeks to put the AIDS epidemic front and center. It’s a short film called Ruth, and it’s based on the experiences of Ruth Coker Burks, an Arkansas housewife who cared for nearly a thousand AIDS patients abandoned by their families in the 1980s.
“She’s an American hero,” McGowan told us at the film’s premiere in Montauk, presented by the non-profit We Are OneTogether, “and one of the many women whose courage and compassion has been buried by silence. It’s our responsibility to tell stories like this, and I consider it an honor.” (It’s also a damn good film, haunting and gorgeous and sad.)
“And some people think this disease isn’t a ‘thing’ anymore, but women are the largest growing segment of the [US] population getting diagnosed with AIDS and HIV.”
Which leads to the question: why are young American women—even educated, progressive, cool girls—often ok with unprotected sex?
“There’s still a stigma that if a woman comes prepared, she’s a whore,” McGowan shrugs bluntly. “Obviously, that can’t be further from the truth, but we’ve got to keep resisting that idea that ‘wanting sex’ or intimacy makes us bad people, or less feminine, or any of that bullshit. Besides insisting on safe sex, I think women can bring their own ‘supplies,’ don’t you?”
Circle. Underline. Copy. Paste. Repeat.
Then take McGowan’s advice and stock up with your local women’s healthcare provider, or at literally any CVS in the country.)
The calls of new-born mice draw the attention of their mother. A group of neuronal cells in the brain stem, which coordinate exhalation and tension of muscles in the larynx is essential for this process. Without these cells, the mice are mute. The cries of human babies may well depend on similar connections, which could also be impaired in speech disorders.
The researchers found that bone retains a “memory” of exercise’s effects long after the exercise is ceased, and this bone memory continues to change the way the body metabolizes a high-fat diet.
With the vision of providing a cell therapy for type 1 diabetes patients, scientists have identified a unique cell surface protein present on human pancreatic precursor cells providing for the first time a molecular handle to purify the cells whose fate is to become cells of the pancreas — including insulin-producing cells.
Scientists have made new insights into the control of cell senescence, which is intimately linked to the development of cancer and aging.
When T cells encounter an antigen, they proliferate and produce various types of daughter cells. Medical researchers have now refuted the prevailing hypothesis that this immune response is largely predetermined by the individual structure of the T cell receptor. Instead, the influence of the T cell receptor can be described only in probabilistic terms. Such mathematical models may help to improve the design of future vaccination strategies.
New research is calling for immediate safeguards and the study of a widely used method for repairing sewer-, storm-water and drinking-water pipes to understand the potential health and environmental concerns for workers and the public.
Using three-dimensional magnetic resonance imaging, a research team characterized the shape, volume, morphometry and texture of placentas during pregnancy and, using a novel framework, predicted with high accuracy which pregnancies would be complicated by fetal growth restriction.
Researchers have found that 86 percent of heterosexuals who are at high risk for HIV would use a home-based test kit provided by mail and 99 percent would seek treatment based on a positive result. This self-administered alternative may lead a group whose high risk is under-recognized to treatment sooner.
