The Negev desert of southern Israel is renowned for its unique rock art. Since at least the third millennium BCE, the hunters, shepherds, and merchants who roamed the Negev have left thousands of carvings (petroglyphs) on the rocks. These figures are mostly cut into desert
Researchers have discovered several rare types of helper T cells that are associated with immune disorders such as multiple sclerosis, rheumatoid arthritis, and even asthma. The discoveries were made possible by a newly developed technology they call ReapTEC. The new T cell
In recent years global warming has left its mark on the Antarctic ice sheets. The 'eternal' ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its formation, as an international
Certain pieces of DNA have been labeled as 'selfish genetic elements' due to notions that they don't contribute to a host organism's survival. Instead, researchers have now discovered that these elements have been weaponized and play a crucial role by cutting off a competitor's
Exposure to wind-blown dust from exposed playa of the Utah lake is worse in Hispanic neighborhoods, according to new research. Findings suggest restoring the lake could ease social inequities associated with air pollution.
Pseudomonas aeruginosa -- an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions -- evolved rapidly and then spread globally over the last 200 years, probably driven by changes in human
The World Meteorological Organization, which is tracking Hurricane Beryl's deadly course through the Caribbean, told AFP that more storms with its hallmarks could be expected in the future.
Soil respiration is the result of heterotrophic respiration (Rh) and autotrophic respiration (Ra), accounting for about 50%–75% of the total ecosystem respiration on land, which is crucial for the global carbon cycle and plays an indispensable role in biogeochemical models.
Tourist resorts in Mexico's Yucatan Peninsula girded Thursday for a hit from Hurricane Beryl, which is still packing ferocious winds after slamming Jamaica and then the Cayman Islands.
Sweet flavors and healthy ingredients make strawberries one of the world's most popular berries. The complex biochemical compounds that determine the flavor and nutritional value of a strawberry—known as biomarkers—can only be determined in detail by experts using modern
Pseudomonas aeruginosa—an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions—evolved rapidly and then spread globally over the last 200 years, probably driven by changes in human behavior, a
In recent years, global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its formation, as an international
Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought.
Australian teenagers have grown up with abundant choices in digital screen entertainment including social media, gaming and streaming video.
Increasingly low-cost environmental sensors coupled with AI-powered analytical tools dangle the promise of faster and more insightful environmental planning.
The most seductive culinary myths have murky origins, with a revolutionary discovery created by accident, or out of necessity.
Carbon in the atmosphere is a major driver of climate change. Now researchers from McGill University have designed a new catalyst for converting carbon dioxide (CO2) into methane—a cleaner source of energy—using tiny bits of copper called nanoclusters. While the traditional
Soil organic carbon (SOC) can be divided into plant-derived and microbial-derived carbon. Studying the latitudinal variation of these two sources and their controlling factors is critical to understanding SOC persistence and stabilization.
Hurricane Beryl swept past the Cayman Islands Thursday en route to Mexico, threatening to bring gusting winds and storm surge after battering Jamaica's southern coast.
New findings challenge the idea that academically selective schools are necessary for clever pupils to achieve good outcomes.
Painting roofs white or covering them with a reflective coating would be more effective at cooling cities like London than vegetation-covered 'green roofs,' street-level vegetation or solar panels, finds a new study led by UCL researchers.
A start-up in Albania, backed by a mining industry billionaire, is farming plants to harvest carbon-neutral nickel from the soil while simultaneously removing carbon dioxide from the atmosphere
From podcasts to shorts, the topic of serial killers is likely to receive a significant amount of attention on social media sites. But what is it about this subject that captures the imagination of millions?
Dr. Doug Clark (Ph.D.) has crawled into many polar bear dens as a graduate student and in a former job as a park warden.
We all make mistakes at work. And many factors can contribute to professional lapses, including fatigue, illness and lack of training or professional support. Usually we pick up the pieces and move on.
Many caterpillars are known for their specific food preferences, which they bring with them when they morph into butterflies. For instance, the monarch butterfly only feeds on milkweed plants, while the Lime butterfly feeds on lime leaves. Despite deriving from a common
