Humans aren’t the only animals that have names for each other − and studying animals that use names can teach researchers more about how human names evolved.
Targeted marketing may play a role in increasing alcohol consumption among women.

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.

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.
Surface bubble growth can lift objects upward against gravity.

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.
Chimp mothers take on the critical role of playmate with their young.

Like all people, the way scientists see the world is shaped by biases and expectations, which can affect how they record and report. Rigorous research methods can minimize this effect.
How cancer vaccines are delivered into the body influences their effectiveness.

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.
In the U.S., if you waive your Miranda rights, you’ll be interrogated – whether you’re drunk or sober.

Legal psychology researchers are investigating how police treat drunken suspects, how impaired people behave when questioned, and how juries consider their statements.
Certain chemicals in synthetic fabrics such as spandex, nylon and polyester can alter the skin microbiome.

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.
If the government takes grizzly bears off the Endangered Species List, some states will likely introduce a hunting season.

There are many ways to kill microbes that cause dangerous infections. Combining genetic screening with machine learning can help researchers identify new antimicrobials.
Identifying the most effective cancer treatment for a given patient from the get-go can help improve outcomes.

Functional precision medicine works to take the guesswork out of deciding which drug to try next for patients with cancers that don’t respond to standard treatments.
Multiple gene variants are linked to Parkinson’s disease, but which ones are the most relevant?

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.

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.
