A new study is providing insight into how different generations are interpreting the use of emojis in their communications, with older adults unsure of how to use them as frequently as younger adults despite understanding their meaning.

In a new study, participants' levels of consumption of refined carbohydrates were statistically linked with their facial attractiveness as rated by heterosexual volunteers of the opposite sex.

Males and females have differential physiological responses to COVID-19 infections, with males having larger increases in skin temperature, breathing rate and heart rate during an acute infection, according to a new study that used data from wearable devices.

Certain factors associated with developing age-related hearing loss differ by sex, including weight, smoking behavior, and hormone exposure, according to a new study.

An injectable hydrogel can mitigate damage to the right ventricle of the heart with chronic pressure overload, according to a new study. In 2019, this same hydrogel was shown to be safe in humans through an FDA-approved Phase 1 trial in people who suffered a heart attack. As a result of the new preclinical study, the FDA approved an investigational new drug application to start a clinical trial with the hydrogel in pediatric patients in the coming months, once institutional approvals are received.

Marine biologists have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica.

A groundbreaking nanosurgical tool -- about 500 times thinner than a human hair -- could be transformative for cancer research and give insights into treatment resistance that no other technology has been able to do, according to a new study.

New research finds around a quarter of Labrador retriever dogs face a double-whammy of feeling hungry all the time and burning fewer calories due to a genetic mutation.

A type of nanoparticle called a metal organic framework (MOF) could be used to deliver vaccines and act as an adjuvant. Researchers find these particles provoke a strong immune response by activating the innate immune system through cell proteins called toll-like receptors.

Unmanned Aerial Vehicles (UAVs) are beneficial in search and rescue missions during natural disasters like earthquakes. However, current UAVs depend on visual information and cannot detect victims trapped under rubble. While some studies have used sound for detection, the noise from UAV propellers can drown out human sounds. To address this issue, researchers have developed a novel artificial intelligence-based system that effectively suppresses UAV noise and amplifies human sounds.

It would be a game-changer if all members of a basketball team could see out of each other's eyes in addition to their own. Biologists have found evidence that this kind of collective sensing occurs in close-knit groups of African weakly electric fish, also known as elephantnose fish. This instantaneous sharing of sensory intelligence could help the fish locate food, friends and foes.

A new study provides a new comprehensive look at the potential for flooding in a combined 32 cities along the Atlantic, Pacific, and Gulf coasts. It predicts as many as 500,000 people will be affected by flooding alongside 1 in 35 privately owned properties within the next three decades, and it highlights the racial and socioeconomic demographics of those potentially affected.

Artificial intelligence helped clinicians to accelerate the design of diabetes prevention software, a new study finds.

If you recently had trouble figuring out if an image of a person is real or generated through artificial intelligence (AI), you're not alone. A new study found that people had more difficulty than was expected distinguishing who is a real person and who is artificially generated.

A specific gene may play a key role in new treatments that prevent muscle in the body from breaking down in serious muscle diseases, muscular dystrophies.

Chemists are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater.

Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs, according to new research.

Every year, more than one million deaths globally occur because of exposure to short-term (hours to days) fine particulate matter (PM2.5) in air pollution, according to a new report, with Eastern Asia reporting more than 50% of deaths attributable to short-term PM2.5 globally.

In good news for office workers, a new study from the University of Sydney, Australia has found increasing your step count may counteract the health consequences of too much sedentary time each day.

A nanotechnology pioneer has uncovered a transformative approach to harnessing the catalytic power of aluminum nanoparticles by annealing them in various gas atmospheres at high temperatures.
