Striking lane-like patterns found in bacteria populations
It's well understood that populations of species don't distribute at random. Rather, as populations grow, individuals are organized around barriers in the landscape. This organization can be seen in, for example, the growth of the cells around the ou.....»»
Strange Visual Auras Could Hold the Key to Better Migraine Treatments
Research on the visual patterns that foreshadow migraines may reveal clues on how painful headaches arise from the brain even though it has no pain receptors......»»
How humans are affecting the Northern Hemisphere"s wind patterns
The summer of 2024 was the hottest on record and, unfortunately, this came as no surprise. Summers have been getting hotter and drier around the world, including in the Northern Hemisphere, leading to intense droughts and heat waves in North America.....»»
Plant pathogen battle: A tomato protein"s dual role in defense and susceptibility
Tomatoes, a staple crop worldwide, are increasingly threatened by biotic stressors such as viruses, fungi, and bacteria, with the effects worsening under climate change. These challenges lead to reduced yields and compromised nutritional quality, hig.....»»
Small populations of Stone Age people drove dwarf hippos and elephants to extinction on Cyprus
Imagine growing up beside the eastern Mediterranean Sea 14,000 years ago. You're an accomplished sailor of the small watercraft you and your fellow villagers make, and you live off both the sea and the land......»»
Harmless strain of E. coli bacteria may be able to prevent urinary tract infections
Researchers from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) and the College of Engineering are collaborating on a project that uses harmless strains of E. coli bacteria to disrupt the bacteria responsible for urinary.....»»
Scientists identify 18 bacterial strains to treat antibiotic-resistant gut infections
Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enteroba.....»»
Hidden Patterns Show Nobel Prize Science Trends
Time lags between discoveries and awards show how the Nobel Prizes reward science.....»»
Students prefer teacher feedback over AI feedback, research finds
Feedback plays a crucial role in learning, helping individuals to understand and improve their performance, yet globally large and diverse student populations often mean that providing timely and personalized observations can be a challenge......»»
Pollen affects cloud formation and precipitation patterns, researchers find
Ground-based and satellite observations in the United States show that increased pollen concentrations in spring lead to more cloud ice and more precipitation—even at temperatures between minus 15 and minus 25 degrees Celsius......»»
Do bacteria age?
Any organism that lives, grows and reproduces must also age. People often think of aging in the physical sense—gray hair, slowed movements and wrinkles—but aging fundamentally occurs on a molecular level, inside of cells......»»
Scientists decipher the energy patterns in our cells
Our cells harness energy for essential functions such as division, wound healing, and our immune response to diseases including cancer. But until now, the mechanics of how that energy affects cell behavior—and how this relates to health outcomes—.....»»
Driver assists become de facto autopilots as drivers multitask, study finds
As drivers become familiar with the systems, they exploit them. Enlarge / Lane keeping systems let you take your hands off the wheel while you drive. (credit: Getty Images) The seductive lure of cars that drive themselv.....»»
Disappearing scientists: Attrition and retention patterns of 2.1 million scientists in 38 OECD countries
Research has been showing that women scientists continue to disappear from science at a significantly higher rate and in higher percentages than men. This is what social scientists have thought for decades—but this is no longer the case today, acco.....»»
Unveiling soil moisture patterns with advanced navigation tech
A pioneering method for soil moisture retrieval using satellite navigation systems has been introduced, significantly boosting the accuracy and efficiency of global data collection. The research, published in the journal Satellite Navigation, tackles.....»»
Soil pH drives microbial community composition: Study shows how bacteria work together to thrive in difficult conditions
Though a founding concept of ecology suggests that the physical environment determines where organisms can survive, modern scientists have suspected there is more to the story of how microbial communities form in the soil......»»
How bacteria actively use passive physics to make biofilms
When we think about bacteria, we may imagine single cells swimming in solution. However, similarly to humans, bacterial cells often socialize, using surfaces to coalesce into complex heterogeneous communities called biofilms. Within a group, bacteria.....»»
How the oceans" most abundant bacteria impact global nutrient flows
If you were to collect all the organisms from the ocean surface down to 200 meters, you'd find that SAR11 bacteria, though invisible to the naked eye, would make up a fifth of the total biomass. These bacteria, also known as Pelagibacterales, have ev.....»»
How to watch NASA’s oldest active astronaut launch to the ISS on Wednesday
Don Pettit isn't your average senior citizen. Instead of enjoying life in the slow lane, he's getting ready for a rocket ride to the ISS......»»
Cloud atlas of Mars showcases array of atmospheric phenomena
Cloud enthusiasts have a new tool to investigate striking formations in the skies above the red planet. A browsable database of 20-years-worth of images of clouds and storms, created by the German Aerospace Centre (DLR) in Berlin, is helping scientis.....»»
Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
The Salish Sea—the inland coastal waters of Washington and British Columbia—is home to two unique populations of fish-eating orcas, the northern resident and the southern resident orcas. Human activity over much of the 20th century, including red.....»»
