Astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a 'radio-loud' quasar -- a bright object with powerful jets emitting at radio wavelengths -- that is so far away its light has taken 13…

Immune cells accessing cerebrospinal fluid faithfully recapitulate the characteristics of cells identified in brain metastasis, and could therefore constitute novel biomarkers of response to immune-based therapies.

Multinational companies headquartered in countries with tougher environmental policies tend to locate their polluting factories in countries with more lax regulations, a new study finds. While countries may hope their regulations will reduce emissions of…

A meta-analysis finds that vision impairment and blindness are tied to an increased risk of mortality, prompting the need to address global eye health disparities.

Studies show that engaging high school girls in physics before they begin formal studies gives them an edge, and helping K-12 teachers incorporate engineering concepts in the classroom boosts their students -- and themselves.

Public grants to build rural broadband networks may not be sufficient to close the digital divide, new research finds.

A research team is a 3D printing method called stereolithography and jelly-like materials known as hydrogels to develop a 3D printing method that's 10-50 times faster than the industry standard. The team says its progress toward 3D-printed human tissue and…

New research describes novel achievements designed to make the implementation of gene drives safer and more controllable. The new split drive and home-and-rescue systems address concerns about the release of gene drives in wild populations.

The process of egg formation in fruit flies relies on physical phenomena analogous to the exchange of gases between balloons of different sizes, according to a new study by biologists and mathematicians.

The first trek of NASA's largest, most advanced rover yet on the Red Planet marks a major milestone before science operations get under way.

Could cactus pear become a major crop like soybeans and corn in the near future, and help provide a biofuel source, as well as a sustainable food and forage crop? Researchers believe the plant, with its high heat tolerance and low water use, may be able to…

Nuisance flooding has increased on U.S. coasts in recent decades due to sea level rise, and new research has uncovered an additional reason for its added frequency -- higher local tide ranges.

Researchers have successfully reprogrammed a glial cell type in the central nervous system into new neurons to promote recovery after spinal cord injury -- revealing an untapped potential to leverage the cell for regenerative medicine.

Researchers found large quantities of previously undetectable compounds from the family of chemicals known as PFAS in six watersheds on Cape Cod using a new method to quantify and identify PFAS compounds. Exposures to some PFAS, widely used for their ability…

Investigators proposes a new, noninvasive way to test for transplant rejection using exosomes -- tiny vesicles containing mRNA -- from urine samples.

In its large caldera, Newberry volcano (Oregon, USA) has two small volcanic lakes, one fed by volcanic geothermal fluids (Paulina Lake) and one by gases (East Lake). These popular fishing grounds are small windows into a large underlying reservoir of…

New research finds that specific regions of the brain respond to emotional stimuli related to loneliness and wisdom in opposing ways.

Comet Catalina is helping explain more about our own origins as it becomes apparent that comets like Catalina could have been an essential source of carbon on planets like Earth and Mars during the early formation of the solar system.

A study of national data shows the devastating impact the pandemic has had on those with intellectual disabilities and their caregivers.

Researchers have developed a new method for detecting small earthquake tremors and successfully applied it to the Nankai Trough, Japan. The technique allowed the accurate estimation of tremor location and propagation speed, leading to the first estimates of…

Studies of the microbiome in the human gut have largely overlooked non-bacterial microbes: viruses, protists, archaea and fungi. Now research in mice points to a significant role for fungi, called the mycobiome, in the intestine.

A new analysis of collisions conducted at different energies at the Relativistic Heavy Ion Collider (RHIC) shows tantalizing signs of a critical point -- a change in the way that quarks and gluons, the building blocks of protons and neutrons, transform from…

Adhesions are scars in the abdomen, which can occur after surgery, often have serious consequences. Now, researchers have discovered how such adhesions form. The findings may help to develop a drug to prevent adhesions in the future.

Findings reveal that demographics such as race and population density, as well as health indices such as cancer rates and food insecurity, show strong correlations with water quality across Virginia.

In recent years, therapeutic antibodies have transformed the treatment of cancer and autoimmune diseases. Now, researchers have developed a new, efficient method based on the genetic scissors CRISPR-Cas9, that facilitates antibody development.

Researchers have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching.

DNA sequencing of bacteria found in pigs and humans in rural eastern North Carolina, an area with concentrated industrial-scale pig-farming, suggests that multidrug-resistant Staphylococcus aureus strains are spreading between pigs, farmworkers, their families…

Two thirds of children use more than one screen at the same time after school, in the evenings and at weekends as part of increasingly sedentary lifestyles, according to new research.

A new study finds a possible link between slow walking pace and an increased risk of death among cancer survivors. The researchers say more work is needed to see if physical activity programs or other interventions could help cancer survivors improve their…

Insects that fall from the surrounding forest provide seasonal food for fish in streams. Researchers have shown that the lengthening of this period has a profound effect on stream food webs and ecosystem functions. These research results provide proof that…
