A new article describes a longer-lasting, 3D-printed, adhesive-free wearable capable of providing a more comprehensive picture of a user’s physiological state.

A new study reveals that a single gene plays a big role in how the liver stores energy, a process that’s critical for overall health and for managing diseases like type 2 diabetes. The research focuses on the PPP1R3B gene. This gene tells the liver how to handle energy: store it as glycogen (a form of sugar) or triglycerides (a type of fat).

A groundbreaking new study introduces an AI-powered smartphone app that noninvasively screens for anemia using a photo of a user’s fingernail. The study shows the app provides hemoglobin estimates comparable to traditional lab tests, with over 1.4 million tests conducted by 200,000+ users. An estimated 83 million Americans and more than 2 billion people globally are at high risk for anemia — populations that stand to benefit significantly from this accessible screening tool. The app offers a low-cost, scalable solution that enhances access, especially in underserved and remote communities, while enabling real-time health monitoring and earlier intervention.

Researchers have shown in mice that brain cells known as astrocytes are required for a signaling chemical called norepinephrine to modify brain activity, changing the textbook understanding that norepinephrine acts directly on neurons.

The combination of air pollution, dense urban development and limited green spaces increases the risk of asthma in both children and adults.

Researchers have developed a method to confidently produce blood cell precursors from stem cells in mice, by activating a set of seven key genes in the laboratory. The team takes a step forward towards the production of precursor cells able to restore the bone marrow of blood cancer patients, in a successful example of regenerative medicine.

Psychological treatment can relieve pain. New research now shows what happens in the brain — and what specific treatments psychologists, doctors and patients can turn to.

Researchers describe a fundamental mechanism of antibiotic resistance. What happens in a bacterium that is resistant to the antibiotic fusidic acid? With a stop-motion movie at the atomic level, they can show that the resistance protein FusB works nearly like a crowbar.

Dementia usually affects older people, so when it occurs in middle age, it can be hard to recognize. The most common form is frontotemporal dementia (FTD), which is often mistaken for depression, schizophrenia, or Parkinson’s disease before the correct diagnosis is reached.

Researchers have discovered how a parasite that causes malaria when transmitted through a mosquito bite can hide from the body’s immune system, sometimes for years. It turns out that the parasite, Plasmodium falciparum, can shut down a key set of genes, rendering itself ‘immunologically invisible.’
