Researchers have profiled the molecular structure and features of a key part of the deadly Nipah virus. Experiments in cells showe how changes in the viral polymerase -- a protein involved in viral replication -- can alter the virus's ability to make copies of itself and infect cells. Further analysis revealed parts of the Nipah virus polymerase that may render the pathogen susceptible to drugs. Read more ›

A new study has described a phenomenon researchers refer to as 'contagious urinations.' The study in 20 captive chimpanzees living at the Kumamoto Sanctuary in Japan shows that, when one chimp pees, others are more likely to follow. Read more ›

Researchers have determined how children's immune systems react to different kinds of cancer depending on their age. The study reveals significant differences between the immune response of children and adults, and has the potential to lead to new tailored treatments for children with cancer. Read more ›

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the 'dark side' of the genome, researchers have now revealed their crucial role in early embryo development. Read more ›

People with pockets of fat hidden inside their muscles are at a higher risk of dying or being hospitalized from a heart attack or heart failure, regardless of their body mass index, according to new research. This 'intermuscular' fat is highly prized in beef steaks for cooking. However, little is known about this type of body fat in humans, and its impact on health. This is the first study to...

Ecologists have identified significant ecological risks associated with the release of hybrid groupers into Hong Kong's coastal waters, a practice often linked to religious 'mercy release' rituals. Their study highlights how the Tiger Grouper-Giant Grouper hybrid (TGGG), also known as the Sabah grouper, disrupts local marine ecosystems by exploiting unique ecological niches and potentially becoming a dominant predator. This research, the first to use advanced DNA metabarcoding to analyze the... Read more ›

In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way -- the magnificent Andromeda galaxy (Messier 31). It can be seen with the naked eye on a very clear autumn night as a faint cigar-shaped object roughly the apparent angular diameter of... Read more ›

Across most of the Northeast, getting bitten by a blacklegged tick-- also called a deer tick -- is a risk during spring, summer, and fall. A new Dartmouth study, published in Parasites and Vectors, finds that 50% of adult blacklegged ticks carry the bacteria that causes Lyme disease while 20% to 25% of the younger (nymph) blacklegged ticks carry the bacteria.

Astrophysicists have imaged a large number of exocomet belts around nearby stars, and the tiny pebbles within them. The crystal-clear images show light being emitted from these millimeter-sized pebbles within the belts that orbit 74 nearby stars of a wide variety of ages -- from those that are just emerging from birth to those in more mature systems like our own Solar System.

Astronomers have now produced the highest resolution direct images ever taken of a supermassive black hole in the infrared, using the Large Binocular Telescope Interferometer. Read more ›

Human ancestors like Australopithecus -- which lived around 3.5 million years ago in southern Africa -- ate very little to no meat, according to new research. This conclusion comes from an analysis of nitrogen isotope isotopes in the fossilized tooth enamel of seven Australopithecus individuals. The data revealed that these early hominins primarily relied on plant-based diets, with little to no evidence of meat consumption. Read more ›

Scientists explored the evolutionary success of leaf beetles, the most diverse herbivores on Earth. They showed that symbioses with bacteria have evolved repeatedly and independently in different beetle lineages, and contribute significantly to the efficient digestion of plant food. These symbiotic relationships provide clues as to how genetic material was exchanged between bacteria and beetles. Key findings highlight the role of horizontal gene transfer, the incorporation of foreign bacterial genetic... Read more ›

Resembling the interlocking links in chainmail, novel nanoscale material is incredibly strong and flexible. The interlocked material contains 100 trillion mechanical bonds per 1 square centimeter -- the highest density of mechanical bonds ever achieved. Small amounts of the mechanically interlocked polymer added to Ultem fibers increased the high-performance material's toughness. Read more ›

Increasingly common since 1980, persistent multi-year droughts will continue to advance with the warming climate, warns a new study. This publicly available forty-year global quantitative inventory seeks to inform policy regarding the environmental impact of human-induced climate change. It also detected previously 'overlooked' events. Read more ›

New research reveals that drought and increased temperatures in a CO2-rich climate can dramatically alter how grasslands use and move water. The study provides the first experimental demonstration of the potential impacts of climate change on water movement through grassland ecosystems, which make up nearly 40% of Earth's land area and play a critical role in Earth's water cycle.

Leo P, a small galaxy and a distant neighbor of the Milky Way, is lighting the way for astronomers to better understand star formation and how a galaxy grows. Scientists have reported finding that Leo P 'reignited,' reactivating during a significant period on the timeline of the universe, producing stars when many other small galaxies didn't. Read more ›

Pandora, a small satellite mission poised to provide in-depth study of at least 20 known planets orbiting distant stars to determine the composition of their atmospheres cleared an important milestone by completing the spacecraft bus, which acts as the spacecraft's 'brains.' Read more ›

4,900 years ago, a Neolithic people on the Danish island Bornholm sacrificed hundreds of stones engraved with sun and field motifs. Archaeologists and climate scientists can now show that these ritual sacrifices coincided with a large volcanic eruption that made the sun disappear throughout Northern Europe. Read more ›
