Career interest tests can be very helpful for teenagers and young adults deciding which career to pursue. New research from Michigan State University challenges the assumption that vocational interests are only relevant for early career decision-making; rather, they remain
UK newspapers responded to a major climate ruling by the world's top court by claiming "lawfare" and linking the decision to the U.K.'s proposed handover of the Chagos Islands to Mauritius, a new review of global media coverage has found. The review is titled Frames in
Many animals exhibit fascinating collective behaviors, which allow them to move, search for food, reproduce and avoid threats more effectively than they would alone. One of these behaviors is queuing migration, which essentially entails traveling as a group in an organized line
Galapagos sharks have been spotted scrubbing off parasites with help from manta rays
Researchers from Sun Yat-sen University and collaborating institutions have discovered a new species of bumblebee goby on Hengqin Island in Guangdong Province, marking the first recorded presence of this fish genus in China. The discovery and description of Brachygobius jennie,
A small clinical trial suggests that probiotics may offer a surprising mental health boost for older adults with depression. Seniors who took a daily probiotic alongside their regular antidepressant treatment experienced slightly greater improvements in depression and anxiety
Neutrinos are one of the fundamental particles of the universe. They live a ghostly existence with no electric charge, very little mass and extremely few interactions with matter. They are also the most abundant particles with mass in the universe and can be created through a
SpaceX shares surged again Tuesday, lifting Elon Musk's rocket company into the world's top five in market value for most of the session as a record-breaking IPO gave way to a torrid buying frenzy.
A clever nanoscale redesign may have solved one of superconductivity’s biggest problems. Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at higher temperatures and under
A Tasmanian devil named Mary has been found in an "unstable condition" more than two weeks after escaping her enclosure, an Australian wildlife park said Wednesday.
A new technique could solve one of the biggest challenges in making future computer chips from ultrathin materials. Researchers found that coating molybdenum disulfide with oxygen or fluorine lets manufacturers remove just the top layer of atoms much more safely during plasma

Scientists are beginning to explore a hidden world of thousands of food chemicals that go far beyond the nutrients listed on nutrition labels. This “nutritional dark matter” may hold the key to understanding disease risk, healthy aging, and why different diets affect people in
Greenland has a long and checkered history of human settlement: several Paleo-Inuit cultures since approximately 2,500 BCE, descendants of Vikings between the 10th and 15th centuries, and early modern Danes since 1721. All left their traces on the landscape, for example in the
It is becoming increasingly urgent to study the effects of climate change on the global ocean system. Future projections indicate significant changes in the Mediterranean and Atlantic circulation systems, which could have unpredictable climatic consequences, especially for one
The body size, morphology and associated behavioral traits of flower-visiting insects strongly influence the quantity of pollen they transport. Thus, pollinators with similar appearances are often assumed to exert similar ecological effects on plants. However, pollinators'
Indian millets are a staple for the country's population of more than a billion. They are also gaining global popularity, with rising exports and a reputation as a climate-resilient crop. Now, new research shows that their nutritional value includes a rich diversity of lipids,
While the world's most advanced climate models successfully reproduce heat waves once they are underway, they consistently miss key atmospheric processes that trigger these events, potentially limiting the ability to anticipate extreme heat several days in advance.
Depression appears to change what children notice in the faces around them, but the effect depends on family history. Kids with a higher inherited risk became more focused on sadness, while lower-risk children lost some of their natural attention to happy expressions.
Diabetes and dementia appear to be closely intertwined, with each condition potentially influencing the other. Problems with insulin and glucose can affect the brain’s energy supply, increase inflammation, and damage blood vessels linked to memory loss. Researchers are also
Even at this early stage in our spacefaring age, humanity has already begun sending probes that will eventually reach other solar systems, even if that was not their original intention. Five robotic explorers—Pioneer 10 and 11, Voyager 1 and 2, and New Horizons—are all on
