A multidisciplinary team has developed a selective compound that inhibits an enzyme tied to inflammation in people at genetic risk for Alzheimer’s, while preserving normal brain function and crossing the blood-brain barrier.
The findings are published in the journal npj Drug Discovery.
The driver is an enzyme called calcium-dependent phospholipase A2 (cPLA2). The team discovered its role in brain inflammation by studying people who carry the APOE4 gene —the strongest genetic risk factor for Alzheimer’s disease. While many people who have the APOE4 gene don’t develop the disease, those with elevated levels of cPLA2 generally do.
At first glance, some scientific research can seem, well, impractical. When physicists began exploring the strange, subatomic world of quantum mechanics a century ago, they weren’t trying to build better medical tools or high-speed internet. They were simply curious about how the universe worked at its most fundamental level.
Yet without that “curiosity-driven” research—often called basic science—the modern world would look unrecognizable.
“Basic science drives the really big discoveries,” says Steve Kahn, UC Berkeley’s dean of mathematical and physical sciences. “Those paradigm changes are what really drive innovation.”
In this report, researchers link thermogenic adipose tissue (brown/beige fat), best known for heat production, to blood-pressure control via direct fat–blood vessel communication. Using mouse models engineered to lose beige fat identity (via adipocyte-specific disruption of PRDM16), they observed elevated arterial pressure alongside perivascular remodeling, including fibrotic tissue accumulation and marked vascular hypersensitivity to the vasoconstrictor hormone angiotensin II. Mechanistically, loss of beige fat identity increased secretion of QSOX1 (quiescin sulfhydryl oxidase 1), which activated pro-fibrotic gene programs in vascular cells and promoted vessel stiffening; blocking this pathway (including genetic removal of QSOX1 in the model) restored healthier vascular signaling and function. The authors characterize this as a previously underappreciated, obesity-independent axis by which the “quality” (thermogenic vs white-like) of perivascular fat influences vascular stiffness and responsiveness to pressor signals, suggesting QSOX1 and related adipose-derived signals as potential precision targets for future antihypertensive therapies.

Obesity causes hypertension. Hypertension causes cardiovascular disease. And cardiovascular disease is the leading cause of death worldwide. While the link between fat and high blood pressure is clearly central to this deadly chain, its biological basis long remained unclear. What is it about fat that impacts vascular function and blood pressure control?
Now, a new study demonstrates how thermogenic beige fat—a type of adipose tissue, distinct from white fat, that helps the body burn energy—directly shapes blood pressure control. Building on clinical evidence that people with brown fat have lower odds of hypertension, the researchers created mouse models that cannot form beige fat (the thermogenic fat depot in mice that most closely resembles adult human brown fat) to watch what happens when this tissue is lost. They found that the loss of beige fat increases the sensitivity of blood vessels to one of the most important vasoconstricting hormones (angiotensin II)—and that blocking an enzyme involved in stiffening vessels and disrupting normal signaling can restore healthy vascular function in mice. These results, published in Science (opens in new window), reveal a previously unknown mechanism driving high blood pressure and point toward more precise therapies that target communication between fat and blood vessels.

Light is a universal stimulus that influences all living things. Cycles of light and dark help set the biological clocks for organisms ranging from single-celled bacteria to human beings. Some bacteria use photosynthesis to convert sunlight into energy just like plants, but other bacteria sense light for less well-known functions.
In 2019, Sampriti Mukherjee, Ph.D., and her team at the University of Chicago discovered that far-red light, part of the light spectrum near the infrared range, prevents the formation of biofilms by the human pathogen Pseudomonas aeruginosa.
Biofilms form when communities of bacteria cluster together and attach to surfaces like medical devices or tissues. Pseudomonas aeruginosa is an antibiotic-resistant bacterium, normally found in the soil and water, that is known to cause difficult to treat infections in hospitalized patients, especially those with weakened immune systems, lung diseases, or large wounds like burns. Figuring out how to prevent this pathogen from forming biofilms could help treat these dangerous infections.
For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory instruments called spectrometers. These devices work by taking light, spreading it out into a rainbow using a prism or grating, and measuring the intensity of each color. The problem is that spreading light requires a long physical path, making the device inherently bulky.
A recent study from the University of California Davis (UC Davis), reported in Advanced Photonics, tackles the challenge of miniaturization, aiming to shrink a lab-grade spectrometer down to the size of a grain of sand, a tiny spectrometer-on-a-chip that can be integrated into portable devices. The traditional approach of spatially spreading light is abandoned in favor of a reconstructive method.
Instead of physically separating each color, the new chip uses only 16 distinct silicon detectors, each engineered to respond slightly differently to incoming light. This is analogous to giving a handful of specialized sensors a mixed drink, with each sensor sampling a different aspect of the drink. The key to deciphering the original recipe is the second part of the invention: artificial intelligence (AI).

A new analysis of soldiers attempting to join the U.S. Army Special Forces suggests that specific genetic variations play a role in how individuals handle extreme physical and mental pressure. The research identified distinct links between a soldier’s DNA and their cognitive performance, psychological resilience, and physiological stress response during a grueling selection course. These findings were published recently in the academic journal Physiology & Behavior.
To become a member of the elite Army Special Forces, a soldier must first pass the Special Forces Assessment and Selection course. This training program is widely recognized as one of the most difficult military evaluations in the world. Candidates must endure nearly three weeks of intense physical exertion. They face sleep deprivation and complex problem-solving exercises. The attrition rate is notoriously high. Approximately 70 percent of the soldiers who attempt the course fail to complete it. This environment creates a unique laboratory for scientists to study human endurance.
Researchers have sought to understand why some individuals thrive in these punishing environments while others struggle. Resilience is generally defined as the ability to adapt positively to adversity, trauma, or threats. It involves a combination of psychological stability and physiological recovery. While physical training and mental preparation are essential, biological factors also play a substantial role. Genetics help determine how the brain regulates chemicals and how the body processes stress hormones.
