New potential for functional recovery after spinal cord injury

Science Daily - 22 hours 22 min ago
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.

Uncovering hidden forever chemicals

Science Daily - 22 hours 22 min ago
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 to repel heat, water, and oil, are linked to a range of health risks including cancer, immune suppression, diabetes, and low infant birth weight.

Novel urine test developed to diagnose human kidney transplant rejection

Science Daily - 22 hours 22 min ago
Investigators proposes a new, noninvasive way to test for transplant rejection using exosomes -- tiny vesicles containing mRNA -- from urine samples.

Small volcanic lakes tapping giant underground reservoirs

Science Daily - 22 hours 22 min ago
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 hydrothermal fluids, releasing carbon dioxide (CO2) and hydrogen sulfide (H2S) with minor mercury (Hg) and methane into East Lake.

How does your brain process emotions? Answer could help address loneliness epidemic

Science Daily - 22 hours 22 min ago
New research finds that specific regions of the brain respond to emotional stimuli related to loneliness and wisdom in opposing ways.

Comet Catalina suggests comets delivered carbon to rocky planets

Science Daily - 22 hours 22 min ago
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.

After old age, intellectual disability is greatest risk factor for death from COVID-19, study finds

Science Daily - 05/03/2021
A study of national data shows the devastating impact the pandemic has had on those with intellectual disabilities and their caregivers.

Making sense of commotion under the ocean to locate tremors near deep-sea faults

Science Daily - 05/03/2021
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 this fault's permeability -- crucial information in evaluation of earthquake rupture processes.

The gut mycobiome influences the metabolism of processed foods

Science Daily - 05/03/2021
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.

Tantalizing signs of phase-change 'turbulence' in RHIC collisions

Science Daily - 05/03/2021
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 one phase to another. The findings will help physicists map out details of these nuclear phase changes to better understand the evolution of the universe and the conditions in the cores of neutron stars.

Controlling adhesions in the abdomen

Science Daily - 05/03/2021
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.

What can stream quality tell us about quality of life?

Science Daily - 05/03/2021
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.

New method facilitates development of antibody-based drugs

Science Daily - 05/03/2021
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.

Life's rich pattern: Researchers use sound to shape the future of printing

Science Daily - 05/03/2021
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.

Antibiotic-resistant strains of staph bacteria may be spreading between pigs raised in factory farms

Science Daily - 05/03/2021
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 and community residents, and represents an emerging public health threat, according to a new study.

Research identifies impact of teenage screen use

Science Daily - 05/03/2021
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.

Walking pace among cancer survivors may be important for survival

Science Daily - 05/03/2021
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 ability to walk and perhaps increase survival after a cancer diagnosis.

'Falling insect' season length impacts river ecosystems

Science Daily - 05/03/2021
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 changes in forest seasonality also affect the ecosystems of nearby rivers. This finding also highlights the importance of predicting the effects of climate change.
