More of the world’s coastal glaciers are melting faster than ever, but exactly what’s triggering the large-scale retreat has been difficult to pin down because of natural fluctuations in the glaciers’ surroundings. Now, researchers have developed a methodology that they think cracks the code to why coastal glaciers are retreating, and in turn, how much can be attributed to human-caused climate change.
The high heat and low water conditions produced by global warming weaken pine trees’ resistance to disease by hindering their ability to mount an effective defense at the same time that pathogenic fungi in their tissues become more aggressive, new research suggests.
While thinking an unwanted thought could make it more likely to recur, we can proactively control this process
Consumption of seven or more units of alcohol per week is associated with higher iron levels in the brain, according to a study of almost 21,000 people publishing July 14th in the open access journal PLOS Medicine. Iron accumulation in the brain has been linked with Alzheimer’s and Parkinson’s diseases and is a potential mechanism for alcohol-related cognitive decline.
A time travel machine, the $10 billion space observatory is being considered well worth the price tag because it will help answer long-held questions about the big bang and search for signs of alien life, University of Miami astrophysicists maintain.
Women tend to live longer than men but typically have higher rates of illness. Now, new research from University of Georgia suggests these higher rates of illness can be improved by a better diet, one that is high in pigmented carotenoids such as yams, kale, spinach, watermelon, bell peppers, tomatoes, oranges and carrots. These bright-colored fruits and vegetables are particularly important in preventing visual and cognitive loss.
A comprehensive new genetic and statistical study from researchers at the University of Kansas reveals two groups of scrub jays — one in Mexico and one in Texas — deserve status as independent species.
Astronomy postdoc Valerie Payré is on an international team that discovered the origin of the martian meteorite known as Black Beauty, one of the most-studied meteorites in the world. It may hold clues to the development of Earth and other terrestrial planets and help explain why Earth sustains life when its closest neighbor does not.
The emotional context in which eating occurs has been thought to influence eating patterns and diet, with studies finding negative emotions predict excessive calorie intake and poor diet quality.
The seemingly three-dimensional “Cosmic Cliffs” showcases Webb’s capabilities to peer through obscuring dust and shed new light on how stars form. Webb reveals emerging stellar nurseries and individual stars that are completely hidden in visible-light pictures. This landscape of “mountains” and “valleys” is actually the edge of a nearby stellar nursery called NGC 3324 at the northwest corner of the Carina Nebula. So-called mountains — some towering about 7 light-years high — are speckled with glittering, young stars imaged in infrared light. A cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located above the area shown in this image. The blistering, ultraviolet radiation from these stars is sculpting the nebula’s wall by slowly eroding it away. Dramatic pillars rise above the glowing wall of gas, resisting this radiation. The “steam” that appears to rise from the celestial “mountains” is
President Biden unveiled the image of galaxy cluster SMACS 0723, known as Webb’s First Deep Field, during a White House event on Monday, July 11. NASA and its partners will release a series of Webb's first full-color images and data, known as spectra, Tuesday, July 12th during a live NASA TV broadcast.
The first ever exoplanets were discovered 30 years ago around a rapidly rotating star, called a pulsar. Now, astronomers have revealed that these planets may be incredibly rare.
Triptans, a commonly prescribed class of migraine drugs, may also be useful in treating obesity, a new study by scientists at UT Southwestern suggests. In studies on obese mice, a daily dose of a triptan led animals to eat less food and lose weight over the course of a month, the team reported in the Journal of Experimental Medicine.

The Swedish Parliament recently presented its ambition to drastically reduce number of wolves in Sweden – from approximately 400 down to approximately 200. Scientists are now reacting to this goal. In a letter published in Science 18 researchers from 5 countries warn that such a cull would further threaten this already highly vulnerable population.
Scientists have unearthed a treasure trove of artifacts along Mexico’s Yucatán Peninsula. Learn what researchers have discovered about the ancient Maya people and their relationship with this hidden stretch of coast.
Scientists have long puzzled over the gap in the fossil record that would explain the evolution of invertebrates to vertebrates. Vertebrates, including fishes, amphibians, reptiles, birds, mammals, and humans, share unique features, such as a backbone and a skull. Invertebrates are animals without backbones.
With energy costs rising, and the rapidly emerging effects of burning fossil fuels on the global climate, the need has never been greater for researchers to find paths to products and fuels that are truly renewable.
How often do stars live alone? For brown dwarfs — objects that straddle the boundary between the most massive planets and the smallest stars — astronomers need to uncover more examples of their companions to find out. Ace citizen scientist Frank Kiwy has done just that by using the Astro Data Lab science platform at NSF’s NOIRLab to discover 34 new ultracool dwarf binary systems in the Sun's neighborhood, nearly doubling the number of such systems known.

Researchers at University College Cork (UCC) and the Swedish Museum of Natural History examined the end-Permian mass extinction (252 million years ago) that eliminated almost every species on Earth, with entire ecosystems collapsing.
A University of Pittsburgh study suggests that while American workers who work alongside industrial robots are less likely to suffer physical injury, they are more likely to suffer from adverse mental health effects — and even more likely to abuse drugs or alcohol.
Most children and adolescents living in the U.S. have suboptimal scores for cardiovascular health (CVH), according to the first study to use the American Heart Association’s new “Life’s Essential 8” metrics and scoring algorithm for quantifying CVH levels in adults and children. Overall, under 30 percent of 2-19-year-olds had high CVH. The proportion of children with high CVH declined markedly with older age: 56 percent of 2-5-year-old children had high CVH, compared with 33 percent of 6-11-year-olds and 14 percent of 12-19-year-olds.
In The Journal of the Acoustical Society of America, scientists in Denmark review recent experiments and find noise regulations may need to be changed to protect porpoises, seals, and other sea-dwelling mammals. Current guidance for seals and porpoises is based on few measurements in a limited frequency range; the guidance is still valid for these frequencies, but investigators found substantial deviations in recent studies of the impact of low frequency noise on seals and high frequency noise on porpoises.
Most teachers focus on academic considerations when assigning seats. A new study is the first to show that these classroom seat assignments also have important implications for children’s friendships and the enormous influence that teachers wield over the interpersonal lives of children.
Researchers have identified a specific bacterial microbe that, when fed to honey bee larvae, can reduce the effects of nutritional stress on developing bees.
Yevgeniy Vorobeychik doesn’t know exactly what sentience is. Since he’s an engineer, not a philosopher, Vorobeychik can’t say what it’s like to be a bat or a tree or a rock. He can’t quantify the importance of embodiment to consciousness. He’s not even sure that there’s an inherent problem with people reacting to an artificial intelligence in ways similar to how they react to other people.
In a new study sponsored by the Centers for Disease Control and Prevention and published in the New England Journal of Medicine, researchers provide additional evidence that COVID-19 vaccination during pregnancy helps protect babies younger than 6 months from being hospitalized due to COVID-19. The risk of COVID-19 hospitalization among babies was reduced by about 80 percent during the Delta wave (July 1–December 18, 2021) and 40 percent during the Omicron wave (December 19–March 8, 2022).
