Nine different studies exploring animals' relationship to music

Researchers have conducted multiple studies attempting to answer a certain question: do animals like human music? Across species, they observed different results and no clear pattern. Primates appear to prefer silence, and cockatoos appear to dance to funky beats.

Sleep training: risks and benefits

Sleep training, which can range from implementing a nighttime routine to letting your baby cry it out, is controversial, but does it work? While dozens of studies have found sleep interventions to be effective, it appears that many of these studies...

Humans are wired to pick up on each other's emotion, making laughter contagious

The reaction plays a key role in establishing interpersonal connections and relieving stress by releasing endorphins—feel-good hormones. A 2021 study identified at least 65 animal species that produce playful sounds, such as laughter.

Emotional crying is an important and cathartic process

Though babies don't initially produce tears when they cry, this podcast discusses how humans are hardwired to cry throughout life. Most crying research relies on self-reporting of crying and emotions. This podcast notes that there aren't neuroimaging studies of crying—they're quite expensive to complete. As a result, the brain precursors and processes during a bout of crying remain understudied.

Exposing fetuses to certain flavors in the womb could lead to children being less picky eaters

A new study found that 3-year-olds were less averse to the smell of vegetables they had been repeatedly exposed to in utero, suggesting that what mothers eat in late pregnancy can leave a lasting imprint on their children's tastes.

Some claim breathwork can improve mental health, help process trauma, and more

Research shows people who practice breathing exercises see a decrease in depression and stress levels, and that such exercises are about as effective at treating PTSD as conventional approaches. Even something as simple as extending exhales can slow one's heart rate and activate the parasympathetic nervous system.

Playing music enhances the creation, storage, and retrieval of memories

Scans of the brains of individuals who play instruments have shown enhanced connectivity between multiple brain regions—visual, auditory, and motor cortices—and the corpus callosum, which connects the two brain hemispheres. These complex connections are strengthened through practice and then used in other activities that involve both logic and creativity. The brains of musicians also appear to give experiences multiple types of memory tags, such as audio, emotional, and conceptual, improving their processing.

Forcing a smile can actually make you feel slightly better

Activating your smile muscles—in this case, with electrical muscle stimulation that forces the corners of the mouth upward—makes people feel more positive, according to recent research. It won't cure depression, but it can have a small effect. Earlier faux smile research using different nonelectrical techniques had similar results, collectively suggesting that a smile may help brighten your day—even though the mechanisms for the happier result remain unclear.

Just a 10-minute mental health break can yield benefits

The US CDC offers recommendations for alleviating stress in daily life. Short 10-minute breaks can significantly improve mental health, especially when used for activities like deep breathing, dancing, or writing down things you are grateful for. Building meaningful relationships, termed "social connectedness," can also alleviate stress and promote resilience.

People who feel connected to nature also report a higher well-being

Based on data collected from over 38,000 participants across 75 countries, spending time appreciating Earth's beauty appears to increase one's satisfaction with life. Whether it's a hike in the woods, a dip in the ocean, or time spent watching the sunset, the findings held true across a wide range of economic, cultural, and environmental contexts. The findings also indicate that connection to nature fosters experiences of being present and attentive, which are strongly linked to mental health.

Noise pollution from humans and technology alters animal behavior

Animals may experience chronic stress and health issues due to noise pollution, which often interferes with their mating sounds. Due to traffic, nightingales sing louder on weekday mornings, and birds near airports start singing earlier to avoid upticks in takeoffs and landings.

Newborns have a strong sense of smell

Babies are drawn to their mother's smell—and the particular odor of their mother's breast milk—within days, even as their vision remains blurry for months after birth. In the womb, the olfactory center also forms in the early stages of development.

Some data shows cold showers can help with depression

An icy water exposure can lead to the release of norepinephrine, cortisol, dopamine, and other stress hormones that are beneficial, among other potential effects. Some data shows that this type of exposure can help combat depression symptoms among some patients, but more research is still needed. (Some users may encounter a paywall.)

What are baby bonds?

In 2008, Hillary Clinton proposed giving every US newborn a $5,000 government-funded trust, often called a “baby bond,” to help low-income families build long-term wealth. Supporters said it could reduce wealth inequality, while critics argued existing programs like the Child Tax Credit offered similar benefits.

Pediatricians look for a list of behaviors to signal typical hearing development

These markers of typical hearing development among infants and toddlers include turning head to sound sources within the first five months of life, babbling by about 11 months, and trying to imitate simple words by 17 months of age.

50 years of research has focused on unraveling the relationship between music and frisson

One insight reveals that musical passages with surprising volume changes or unexpected harmonies and beauty are more likely to trigger frisson, perhaps because they upend listeners' expectations.

The US trails behind other developed countries in reducing its stillbirth rates and may learn from Australia

Australia is in the vanguard of efforts to bring down stillbirth numbers with a national stillbirth plan integrated into its healthcare system, supported by clinicians, nurses, midwives, and politicians. Its work also includes a public awareness campaign, more regular fetal monitoring and follow-up for potential interventions, and more maternal advice about care and safety during pregnancy.

Shorter, more frequent touches are better than longer, rarer ones

That's according to a 2024 meta-analysis of 137 studies on touch. It found that as long as the touch is consensual, the identity of the toucher mattered little for adults, and there was even a benefit to receiving "touch" from objects like weighted blankets or robots. For newborns, however, the identity of the toucher did matter, and the greatest benefit came from parental touch.

Women more likely than men to report strain of being a caregiver

A Pew Research Center caregiver analysis from 2026 indicates that, though men and women both say caring for aging parents improved their relationships with their parents, women are more likely than men to report that it had a negative impact on their emotional well-being and physical health.

Baby monkeys chose a soft, warm doll over a wire one with food

Harry Harlow performed controversial experiments with newborn monkeys, separating them from their mothers and letting them bond with stand-in mother figures made from either wire or figures covered in cloth—both with monkey-like faces. The work investigated touch, bonding, and attachment, and found that monkeys overwhelmingly preferred the cloth dolls over the wire ones in various stressful situations.

Western babies often lack a gut microbe common elsewhere.

Doctors are prescribing social activities—and seeing good results

Physicians, especially in the UK, are asking patients what they enjoy and then prescribing a consistent regimen of doing that type of activity to improve fitness and overall health, including community exercise classes, volunteering, and spending time in nature. This approach may provide better incentives to stick with an activity.
