A sense of purpose in life — whether it’s a high-minded quest to make a difference or a simple hobby with personal meaning — can offer potent protection against loneliness, according to a new study co-authored by Patrick Hill, associate professor of psychological and brain sciences at Washington University in St. Louis.
Artificial intelligence can bring precision and speed to every sector—defense, healthcare, transportation, education, and more. At the same time, AI poses potential risks to people and property, raising social, ethical, geopolitical, even existential questions.
Carbon compounds form the foundations of all known life, and as such are of a particular interest to scientists working to understand both how life developed on Earth, and how it could potentially develop elsewhere in our universe. As such, the study of interstellar organic (carbon-containing) chemistry is an area of keen fascination to many astronomers. An international team of astronomers has used NASA’s James Webb Space Telescope to detect a carbon compound known as methyl cation for the first time. This molecule is important because it aids the formation of more complex carbon-based molecules. It was found in a young star system with a protoplanetary disk, 1,350 light-years away in the Orion Nebula.
Researchers from Empa and Imperial College London are developing a heat-resistant drone that can analyze the source of danger at close range in the event of a building or forest fire. This allows firefighters to optimize the strategy of a high-risk operation before entering the danger zone.
Influenza A is one of two influenza viruses that fuel costly annual flu seasons and is a near constant threat to humans and many other animals. It’s also responsible for occasional pandemics that, like the one in 1918, leave millions dead and wreak havoc on health systems and wider society. Influenza A was first identified as a health threat nearly a century ago, but only in the last decade have scientists identified one of the virus’s key proteins for infiltrating host cells and short-circuiting their defenses.
A team led by researchers at Harvard Medical School has developed a new tool that promises to improve the way pathologists see and evaluate a tumor by providing detailed clues about the cancer.

As men age, some of their cells lose the very thing that makes them biological males—the Y chromosome—and this loss hampers the body’s ability to fight cancer, according to new research from Cedars-Sinai Cancer.
Researchers at The University of Texas MD Anderson Cancer Center have uncovered a gene on the Y chromosome that is upregulated in KRAS-mutated colorectal cancer (CRC), increasing tumor cell invasiveness and reducing anti-tumor immunity in male patients.
New research from Binghamton University, State University of New York explores how a warming world could impact ecosystems and derail the development of new species.
When some semiconductors absorb light, the process can create excitons, quasi-particles made of an electron bound to an electron hole. Two-dimensional crystals of tungsten disulfide have unique but short-lived exciton states. Scientists developed a new approach called time-resolved momentum microscopy to create separate images of these individual quantum states. The study found that the coupling mechanisms that lead to mixing of the states may not fully match current theories.
Certain conditions can make the increased heart rate associated with exercise dangerous: Researchers found that an elevated heart rate can induce a stroke in patients with highly blocked carotid arteries. Contrastingly, for healthy patients and those with only slightly blocked arteries, exercise is beneficial for maintaining healthy blood flow. In healthy patients, an elevated heart rate increases and stabilizes the drag force blood exerts on the vessel wall, reducing stenosis risk. But for patients already experiencing stenosis, it may not be as beneficial.
An octopus devotes about 70 percent of its brain to vision. But until recently, scientists have only had a murky understanding of how these marine animals see their underwater world. A new University of Oregon study brings the octopus’s view into focus.
In Physics of Fluids, researchers develop a model to explore the forces and flow structures created by penguin wings underwater. Penguin can adjust swimming posture by active wing feathering, pitching, and flapping and their dense, short feathers can also lock air between the skin and water to reduce friction and turbulence. The hydrodynamic model takes in information about the flapping and feathering of the wings and, using the immersed boundary method, solves for the motion of the wing and the thrust, lift, and lateral forces.
New research published in the journal Geophysical Research Letters showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.
NASA’s James Webb Space Telescope has successfully measured the heat radiating from TRAPPIST-1 c, an exoplanet orbiting a red dwarf star 40 light-years from Earth. With a dayside temperature of about 225 degrees Fahrenheit, it is the coolest rocky planet ever characterized using this method.
Unfortunately for those hoping that the TRAPPIST-1 system is a true analog to our own, the results are a bit disappointing. While TRAPPIST-1 c is roughly the same size and mass as Venus and receives the same amount of radiation from its star, it appears unlikely to have the same thick carbon dioxide atmosphere. This indicates that the planet, and perhaps the system as a whole, may have formed with very little water. The result is the latest in the quest to determine whether planetary atmospheres can survive the violent environs of a red dwarf star.
People who have a pattern of heavy drinking showed less impairment than light drinkers after drinking similar amounts of alcohol — yet this difference depends largely on how much time has elapsed after drinking and may only be evident at moderate intoxication. A study published in Alcohol: Clinical and Experimental Research found that people who exceed drinking an amount of alcohol that is typical for them showed substantial impairment. And, when heavy drinkers and lighter drinkers were similarly impaired, the heavy drinkers perceived themselves to be less impaired, which may lead to risky decisions.

Inhaled microplastics can pose serious health risks, so understanding how they travel in the respiratory system is essential for prevention and treatment of respiratory diseases. In Physics of Fluids, researchers develop a computational fluid dynamics model to analyze microplastic transport and deposition in the upper airway. The team explored the movement of microplastics with different shapes and sizes and under slow and fast breathing conditions. Microplastics tended to collect in hot spots in the nasal cavity and oropharynx, or back of the throat.
Repeat treatment with corticosteroid injections improved vision in people with persistent or recurrent uveitis-related macular edema better than two other therapies, according to results from a clinical trial funded by the National Eye Institute (NEI).
The universe is big, and it’s getting bigger. To study dark energy, the mysterious force behind the accelerating expansion of our universe, scientists are using the Dark Energy Spectroscopic Instrument (DESI) to map more than 40 million galaxies, quasars, and stars. Today, the collaboration publicly released its first batch of data, with nearly 2 million objects for researchers to explore.

Only a few hundred million years after the big bang, the cosmos was brimming with opaque hydrogen gas that trapped light at some wavelengths from stars and galaxies. Over the first billion years, the gas became fully transparent – allowing the light to travel freely. Researchers have long sought definitive evidence to explain this flip.
A team led by University of Minnesota Twin Cities physicists has discovered a new way to search for axions, hypothetical particles that could help solve some of nature’s most puzzling mysteries.
Tightly curled scalp hair protected early humans from the sun’s radiative heat, allowing their brains to grow to sizes comparable to those of modern humans. Loughborough University researchers in the UK worked with Penn State University to study heat transfer through human hair wigs and the environment to examine how diverse hair textures affect heat gain from solar radiation.
The growing frequency and intensity of heat waves around the globe pose “a substantial, persistent ‘non-combat threat’” to military training and operations, according to experts in environmental, thermoregulatory and cardiovascular physiology.
Targeted alpha therapy using radioisotopes such as actinium-225 can destroy cancerous cells without harming healthy cells. However, making actinium-225 by bombarding radium targets with neutrons poses a challenge: how to chemically separate the radium from the actinium. A new approach uses radiation-resistant inorganic resin scaffolds as platforms for separating radium, actinium, and lead, improving production time, cost, and safety.
People who have insomnia symptoms such as trouble falling asleep, staying asleep and waking up too early, may be more likely to have a stroke, according to a study published in the June 7, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. In addition, researchers found the risk was much higher in people under 50 years old. The study does not prove that insomnia symptoms cause stroke; it only shows an association.
Prior to being diagnosed with epilepsy, 5% of people with a type of epilepsy called focal epilepsy had a seizure while driving, according to a new study published in the June 7, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology.
When scientists detected the gamma-ray burst known as GRB 221009A on October 9, 2022, they dubbed it the BOAT, or the brightest-of-all-time. Now, scientists studying GRB 221009A describe an unusual structure to the jet of material expelled during the explosion that may explain GRB 221009A’s extreme nature and why its afterglow remained visible for so long after the event.
The myriad ways in which we use social media can be grouped into four broad categories, each of which is associated with a cluster of specific personality and behavioral traits, suggests new research from Washington University in St. Louis. Study authors say: Social media is here to stay, so clarifying how people use social media and raising awareness of these findings are crucial first steps toward ultimately helping people understand how they can avoid the negative aspects of social networking and engage in healthier social media usage.
A new study from Mana Heshmati, assistant professor of strategy and entrepreneurship in the University of Washington Foster School of Business, found that strategy courses in MBA programs improve decision-making abilities, boost the amount of attention paid to broader industry concerns and expand the depth of mental representations.
