Viruses are doing mysterious things everywhere – AI can help researchers understand what they’re up to in the oceans and in your gut

Scientists are discovering viral genetic sequences in the wild faster than they can analyze them. A kind of ChatGPT for proteins can help make sense of all that data.
Iron carries oxygen throughout the body, but ironically, it can also make it harder to breathe for people with asthma. Hiroshi Watanabe/Stone via Getty Images

Iron fuels immune cells – and it could make asthma worse

Asthma attacks can result from immune cells overreacting to a harmless allergen. Tamping down iron levels in certain immune cells can help control their activity.
Organoids can replicate each component of the human heart, from its chambers to its veins. Yonatan R. Lewis-Israeli et al. 2021/Nature Communications

Engineering mini human hearts to study pregnancy complications and birth defects

Human heart organoids allow researchers to study the developing heart while avoiding the ethical issues of using human embryos and the imperfections of animal models.

Brain study identifies a cost of caregiving for new fathers

One of the first longitudinal studies of male brain changes across the transition to first-time parenthood finds that becoming a dad affects the brain – without the direct experience of pregnancy.

Brain cancer in children is notoriously hard to treat – a new mRNA cancer vaccine triggers an attack from within

Cancer vaccines have gained much interest among scientists but face a number of hurdles. A new mRNA vaccine for glioma offers a step forward in training the immune system to fight cancer.
Certain chemicals in synthetic fabrics such as spandex, nylon and polyester can alter the skin microbiome. SBenitez/Moment via Getty Images

Chemical pollutants can change your skin bacteria and increase your eczema risk − new research explores how

From synthetic fabrics to car exhaust to wildfires, exposure to environmental pollutants push the skin microbiome to adapt in ways that reduce its ability to protect the skin.
Multiple gene variants are linked to Parkinson’s disease, but which ones are the most relevant? dra_schwartz/E+ via Getty Images

Newly discovered genetic variant that causes Parkinson’s disease clarifies why the condition develops and how to halt it

No treatments are currently available to cure Parkinson’s disease. Better understanding the genetic foundation of this condition can help researchers find ways to slow or halt its progression.
Genetic analysis of the bacteria causing surgical site infections revealed that many were already present on the patient’s skin. Ruben Bonilla Gonzalo/Moment via Getty Images

Infections after surgery are more likely due to bacteria already on your skin than from microbes in the hospital − new research

Most infection prevention guidelines center on the hospital environment rather than the patient. But the source of antibiotic-resistant microbes is often from the patient’s own body.

Horses lived in the Americas for millions of years – new research helps paleontologists understand the fossils we’ve found and those that are missing from the record

Horse fossils are abundant and widespread across North America. Scientists often use their long history to illustrate how species evolve in response to a changing environment.
Activities that keep you fired up don’t help you turn down your anger. Ray Massey/The Image Bank via Getty Images

Chilling out rather than blowing off steam is a better way to manage anger − new review of 154 studies reveals what works

Activities such as deep breathing, muscle relaxation, yoga and meditation help people manage their anger, according to a meta-analysis of studies involving more than 10,000 participants.

AI can help predict whether a patient will respond to specific tuberculosis treatments, paving way for personalized care

People have been battling tuberculosis for thousands of years, and drug-resistant strains are on the rise. Analyzing large datasets with AI can help humanity gain a crucial edge over the disease.

Female mosquitoes rely on one another to choose the best breeding sites − and with the arrival of spring, they’re already on the hunt

Female mosquitoes don’t want to lay their eggs alone, but they don’t want sites that are too crowded either. Understanding what guides their choice could inform new control strategies.
