There' s no longer any doubt—the wolves found in Norway and Sweden today are actually Finnish, according to extensive studies done on their genetic makeup. Humans wiped out Norway's original wolf population in the wild around 1970.

Ocean predators cannot survive on average concentrations of food found in the water. Instead, they survive by exploiting small patches of food-rich areas peppered throughout the world's waterways.

Researchers at Lawrence Livermore National Laboratory (LLNL) have shown for the first time the potential for linear induction accelerators (LIAs) to deliver effective, targeted doses of "FLASH" radiation to cancer patients. The new technique selectively kills cancer cells with minimal damage to healthy cells. The approach is outlined in a Scientific Reports paper.

Biomedical engineers at Duke University have demonstrated a method for increasing the depth at which optical coherence tomography (OCT) can image structures beneath skin.

Bicultural consumers such as Asian Americans or Hispanic Americans are the fastest growing demographic in the U.S., and one of the challenges marketers face is how to build brands that resonate with consumers who have assimilated norms from different cultures and are able to code-switch between behaviors in response to social cues.

Do others see you as a reckless risk-taker who behaves compulsively without weighing potential consequences? Or a courageous risk-taker who takes responsible risks?

The dusty surface of the moon—immortalized in images of Apollo astronauts' lunar footprints—formed as the result of asteroid impacts and the harsh environment of space breaking down rock over millions of years. An ancient layer of this material, covered by periodic lava flows and now buried under the lunar surface, could provide new insight into the Moon's deep past, according to a team of...

Life is water, and water is life. This truism certainly applies to the Pacific coast, where streams and rivers function as the region's arteries. The water they carry fosters plant life and wildlife in Southern California's Mediterranean climate. They provide sanctuary during droughts and often serve as the nexus for recovery after fires.

There are few places farther from your medicine cabinet than the tissues of an ascidian, or "sea squirt," on the icy Antarctic sea floor—but this is precisely where scientists are looking to find a new treatment for melanoma, one of the most dangerous types of skin cancer.

The warming of the planet is taking a deadly toll on seabirds that are suffering population declines from starvation, inability to reproduce, heat waves and extreme weather.

Researchers in Brazil and Belgium have developed a molecule of pharmaceutical interest from collinein-1, a protein found in rattlesnake venom. They used a technique called PEGylation to make the molecule, now called PEG-rCollinein-1, more stable in the organism and resistant to the immune system, obtaining a drug candidate to modulate blood clotting.

Wheat and barley growers know the devastating effects of Fusarium head blight, or scab. The widespread fungal disease contaminates grain with toxins that cause illness in livestock and humans, and can render worthless an entire harvest. As Fusarium epidemics began to worsen across the eastern U.S. in the 1990s and beyond, fewer and fewer farmers were willing to risk planting wheat.

America needs to rethink and reduce the way it generates plastics because so much of the material is littering the oceans and other waters, the National Academy of Sciences says in a new report.

A brown blotch on a plant leaf may be a sign that the plant's defenses are hard at work: When a plant is infected by a virus, fungus or bacterium, its immune response keeps the disease from spreading by killing the infected cell, as well as a few surrounding ones. A new study at the Weizmann Institute of Science points to the evolutionary origins of this plant immune mechanism. The study may help...

The value of long-term studies can be found when you're ready to dig deep. WUR scientists and European partners asked: what happens when organic farmers stop plowing? In a joint effort, we sampled nine field trials across Europe and assessed the impact of reduced tillage versus plowing on soil carbon storage: Humus was always enriched in the soil surface layer in reduced tillage systems, which is...

Researchers at the Center for Astrophysics | Harvard & Smithsonian have observed a new type of binary star that has long been theorized to exist. The discovery finally confirms how a rare type of star in the universe forms and evolves.

An important player in the healthy development of female embryos turns out also to play a key role in regulating the behavior of chromosome loops and gene expression in both sexes, according to a new study by researchers at Massachusetts General Hospital (MGH). These findings, reported in the journal Cell, could help create new targets for drug development.

Since the tsunami that devastated coasts around the Indian Ocean in December 2004 and the Fukushima disaster in March 2011, people worldwide are aware that geological processes in the ocean can cause significant damage. From a European perspective, such events are seen to occur mostly in distant regions. "It is often forgotten that the European coasts are also located in areas that are...

Equilibrium may be hard to achieve in our lives, but it is the standard state of nature.

Astronomers at The University of Texas at Austin's McDonald Observatory have discovered an unusually massive black hole at the heart of one of the Milky Way's dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies—the building blocks of the universe—evolve. The work is published in a recent...

Researchers from The Hong Kong University of Science and Technology (HKUST) and Hong Kong Baptist University (HKBU) have decoded for the first time the demographic history, genetic structure, and population connectivity of a deep-sea limpet widely distributed in vent and seep ecosystems in the Northwest Pacific. This study not only enhances our knowledge of the historical population divergence and...

Saldanha Bay harbor on the west coast of South Africa has long been an important point for global shipping routes. It was also the port of entry for an unwanted stow-away: the Mediterranean mussel. The species first appeared in South Africa in the late 1980s, and has spread along the west and south coasts. It has displaced native species, increased the areas covered by mussel beds, and damaged...

Schools aren't just where kids go to learn reading, math, science and history. The social skills they learn—like how to build and maintain relationships with peers—are also critical. This is particularly true as schools grapple with the aftereffects of school closures due to the COVID-19 pandemic.

The rhizosphere is the narrow region where plant roots and the soil interact vigorously and intensive microbial metabolism occurs. The properties of rhizosphere soil are usually different from that of non-rhizosphere soil. This is called rhizosphere effects (REs).
