New research has found that two types of weevils, common yet invasive beetles in many parts of the world, have been using epigenetic changes to adapt and respond to different toxins in the plants they eat. The findings have implications for how we consider asexual invaders and how successful they can be because of gene regulation.

Astronomers have developed a new way to capture all the exquisite 'layer-cake' details of a brown dwarf's cloud structure. Because brown dwarfs are similar to super-Jupiters, this innovative technique can help deepen scientists' understanding of the atmospheres of giant alien worlds that are more massive than Jupiter.

Areas with climatic conditions suitable for sustaining permafrost in the Daisetsu Mountains are projected. The size of the area in the Daisetsu Mountains where climatic conditions were suitable for permafrost were estimated to be approximately 150 km2 in 2010. Under the business-as-usual scenario, this area is projected to disappear by around 2070. Under the low-carbon scenario consistent with...

Researchers have shown that a targeted therapy using non-thermal radio waves is safe to use in the treatment of hepatocellular carcinoma (HCC), the most common type of liver cancer, according to a new study. The therapy also showed a benefit in overall survival.

In the biomaterials industry, electrospinning is a ubiquitous fabrication method used to produce nano- to microscale fibrous meshes that closely resemble native tissue architecture. Alas, the process has traditionally used solvents that not only are environmentally hazardous but also a significant barrier to industrial scale-up, clinical translation, and widespread use. But now, researchers report...

Symptoms for early COVID-19 infection differ among age groups and between men and women, new research has found.

Research on a newly discovered bird fossil found that a unique brain shape may be why the ancestors of living birds survived the mass extinction that claimed all other known dinosaurs.

Occurring faster than the speed of sound, the mystery behind the breakdown of plasma discharges in water is one step closer to being understood as researchers pursue applying new diagnostic processes using state-of-the-art X-ray imaging to the challenging subject.

The mutations that give rise to melanoma result from a chemical conversion in DNA fueled by sunlight -- not just a DNA copying error as previously believed, reports a new study. The findings upend long-held beliefs about the mechanisms underlying the disease, reinforce the importance of prevention efforts and offer a path forward for investigating the origins of other cancer types.

Medical researchers have discovered what appears to be an Achilles' heel in ovarian cancers, as well as new biomarkers that could point to which patients are the best candidates for possible new treatments.

Scientists have identified a natural barrier to the regeneration of the inner ear's sensory cells, which are lost in hearing and balance disorders. Overcoming this barrier may be a first step in returning inner ear cells to a newborn-like state that's primed for regeneration, as described in a new study. The study suggests new gene engineering approaches that could be used to channel some of the...

A new paper documents an unusual behavior among tufted titmice and their closest bird kin. A bird will land on an unsuspecting mammal and, cautiously and stealthily, pluck out some of its hair.

Researchers have established an accurate genome assembly of 'Fielder' wheat, which -- unlike other wheat cultivars -- is very amenable to genetic editing through bacterial transformation. This genome sequence was generated using a technique that is easier than previous sequencing methods. The development has important implications for wheat genome-editing research and agriculture.

Researchers have found a new approach to incorporating the larger web of relevant data for predictive modeling for individual and community health outcomes.

An international research team has shown that using solar-panels to produce microbial protein -- which is rich not just in proteins but also in other nutrients -- is more sustainable, efficient and environmentally friendly than growing conventional crops. This method uses solar energy, land, nutrients, and carbon dioxide from the air.

Engineers have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing and communication systems.

Researchers have found evidence that World Trade Center responders had a higher likelihood of developing liver disease if they arrived at the site right after the attacks as opposed to working at Ground Zero later in the rescue and recovery efforts.

A study involving over 26,000 individual graves in England, France, Germany, Belgium, Switzerland and the Netherlands explores the changes to burial practices and use of 'grave goods' between the 6th-8th centuries CE. Although clear regional distinctions and preferences are present, some communities were able to make highly individual choices about the way to bury their dead.

'Panic buying' might be a normal human response to uncertainty after all, new research suggests.

Greater buffer zones around bodies of water and more consistent enforcement of water protection regulations are needed to reduce agriculture-based pollution in the Western U.S., a recent review has found.

Biologists are using comparative metabologenomics to try to uncover what may be 'silencing' Streptomyces and preventing it from producing desirable compounds encoded by its genes.

New research shows that city lights limit the ability of nocturnal animals to navigate by natural light in the night sky. Instead, they are forced to use streetlamps, neon light or floodlights to orient themselves.

Researchers have used advanced electron microscopy (EM) technology to see how human viruses move in high resolution in a near-native environment. The visualization technique could lead to improved understanding of how vaccine candidates and treatments behave and function as they interact with target cells.

Researchers have shown how the amygdala, a brain region typically associated with fear, contributes to prepulse inhibition (PPI) by activating small inhibitory neurons in the mouse brain stem. The discovery advances understanding of the systems underlying PPI and efforts to ultimately develop medical therapies for schizophrenia and other disorders by reversing pre-attentive deficits.
