Researchers reporting November 20, 2020 in the journal Current Biology have found that, in places where the herb is harvested more, the plant has evolved to blend in better with the background, making them harder for people to find. As a result, the plant varies in color from brown or grey to green, depending on whether it lives in a place that is frequented by human collectors or not.
New fluid dynamics research reveals why social distancing alone doesn't necessarily prevent infection indoors and how to detect COVID-19 super-spreaders.
Triclosan, an antimicrobial found in many soaps and other household items, worsens fatty liver disease in mice fed a high-fat diet.
In a recent article in The Quarterly Review of Biology, "Beyond Equilibria: The Neglected Role of History in Ecology and Evolution," author Hamish G. Spencer argues for a revitalized view of history. This historical view is a response to current research in the field of ecology and evolution, which is dominated by an ahistorical view of dynamic systems.
Scientists demonstrate how fires burn and spread under different environmental conditions.
Understanding how the clear, watery substance flows through the brain could yield new insights into health and disease.
Excavations on the south coast of South Africa have uncovered evidence of human occupations from the end of the last ice age, approximately 35,000 years ago, through the complex transition to the modern time, known as the Holocene and adaptions that were key to our species ability to survive wide climate and environmental fluctuations.
Researchers model urban airflows to help improve the design of drones, skyscrapers, and natural ventilation systems.
A multi-institution team co-led by a Cornell University researcher has identified the genetic mechanisms that enable the production of a deadly toxin called Victorin - the causal agent for Victoria blight of oats, a disease that wiped out oat crops in the U.S. in the 1940s.
As wind energy scales up, researchers study the fluid dynamics challenges.
Canine distemper virus (CDV) causes a serious disease in domestic dogs, and also infects other carnivores, including threatened species like the Amur tiger. It is often assumed that domestic dogs are the primary source of CDV, but in a new Cornell University College of Veterinary Medicine study found that other local wildlife was the primary source of CDV transmission to tigers instead.
A new study details the latest efforts to predict traits in corn based on genomics and data analytics. The data management technique could help to "turbo charge" the seemingly endless amount of genetic stocks contained in the world's seed banks, leading to faster and more efficient development of new crop varieties.
Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC Santa Cruz have now achieved the first direct visualization of quantum dots in bilayer graphene, revealing the shape of the quantum wave function of the trapped electrons.
Fluids researchers pivot to create more effective face coverings.
A national research team led by The Jackson Laboratory and the University of Maine discovered that Dlgap2, a gene that helps facilitate communication between neurons in the nervous system, is associated with the degree of memory loss in mice and risk for Alzheimer's dementia in humans. When studying post-mortem human brain tissue, the researchers also discovered low levels of Dlgap2 in people experiencing "poorer cognitive health" and "faster cognitive decline" prior to death.
Faster, smaller, smarter and more energy-efficient chips for everything from consumer electronics to big data to brain-inspired computing could soon be on the way after engineers at The University of Texas at Austin created the smallest memory device yet.
Engineering a spaceship is as difficult as it sounds. Modeling plays a large role in the time and effort it takes to create spaceships and other complex engineering systems. It requires extensive physics calculations, sifting through a multitude of different models and tribal knowledge to determine singular parts of a system's design.
Engineers reveal how zinc oxide nanoneedles and droplet hydrodynamics can stop pathogens.
Studies explore fluids in pancakes, beer, and the kitchen sink.
The largest aggregation of fishes ever recorded in the abyssal deep sea was discovered by a team of oceanographers during an expedition in the Clarion Clipperton Zone. Their findings were published recently in Deep-Sea Research.
