Emory researchers help discover source of deadly fungal infections in bone marrow transplant patients, new study finds

Emory researcher David Weiss has spent years studying a baffling phenomenon called heteroresistance, in which a tiny fraction of bacteria remain resistant to antibiotics, while the remainder succumb. Recently, he brought his scientific acumen to the equally deadly threat of fungal bloodstream infections in patients receiving bone marrow transplants. Bloodstream infections can be lethal in these patients, including infections from Candida parapsilosis, a species of fungi that can live in the digestive tract and occasionally make it into the bloodstream. Weiss partnered ...

Brain activity associated with specific words is mirrored between speaker and listener during a conversation

When two people interact, their brain activity becomes synchronized, but it was unclear until now to what extent this “brain-to-brain coupling” is due to linguistic information or other factors, such as body language or tone of voice. Researchers report August 2 in the journal Neuron that brain-to-brain coupling during conversation can be modeled by considering the words used during that conversation, and the context in which they are used. “We can see linguistic content emerge word-by-word ...

Prescription fills for semaglutide products

About The Study: The number of prescriptions filled for semaglutide has increased substantially, reaching 2.6 million prescriptions filled at retail pharmacies by December 2023. While Ozempic persistently accounted for most semaglutide fills, increases were considerably greater for Wegovy since its approval for weight loss in June 2021. These increases, which primarily occurred following increased awareness of weight-loss benefits in late 2022, are likely contributing to the FDA-reported shortage of Ozempic and Wegovy first issued in March 2022. Despite the disproportionate burden of obesity in Medicaid and Medicare Part D populations, and recent increases in public spending ...

Mast cells trap and use living neutrophils during allergic reactions

Inflammation is the body's response to harmful stimuli, characterized by heat, pain, redness, swelling, and loss of tissue function. When balanced, inflammation protects the body by clearing harmful agents and initiating tissue repair. However, excessive inflammation can cause tissue destruction and disease. Key players in this process are various immune cells, which work together during inflammation. The type of immune cells involved often varies depending on the harmful stimulus, influencing the outcome of the inflammatory response. Immune cell trapping during allergic responses Mast cells, residing in tissues and critical for initiating ...

Exploding popularity of Ozempic and Wegovy among privately insured patients may worsen disparities

A new USC study suggests that publicly insured individuals who are most likely to benefit from new drugs for diabetes and obesity are less likely to get them than those with private insurance. Prescription fills for the drug best known as Ozempic or Wegovy — semaglutide — increased by more than 400% between January 2021 and December 2023, according to research out today in  JAMA Health Forum. Approved first for type 2 diabetes, then for weight loss, studies show that semaglutide also improves blood pressure and reduces cardiovascular disease — problems that plague millions of Americans. Yet the lion’s share of prescriptions ...

What gave the first molecules their stability?

The origins of life remain a major mystery. How were complex molecules able to form and remain intact for prolonged periods without disintegrating? A team at ORIGINS, a Munich-based Cluster of Excellence, has demonstrated a mechanism that could have enabled the first RNA molecules to stabilize in the primordial soup. When two RNA strands combine, their stability and lifespan increase significantly. In all likelihood, life on Earth began in water, perhaps in a tide pool that was cut off from seawater at low tide but flooded by waves at high tide. Over billions of years, complex molecules like DNA, RNA and proteins ...

Scientists find a human “fingerprint” in the upper troposphere’s increasing ozone

Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun’s harsh ultraviolet rays. But closer to the ground, ozone is a harmful air pollutant that can trigger chronic health problems including chest pain, difficulty breathing, and impaired lung function.  And somewhere in between, in the upper troposphere — the layer of the atmosphere just below the stratosphere, where most aircraft cruise — ozone contributes to warming the planet as a potent greenhouse gas. There are signs that ozone is continuing to rise in the upper troposphere despite efforts to reduce its ...
