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...
Novel urine test developed to diagnose human kidney transplant rejection

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
- ScienceDaily
- 21/3/5 19:37
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
- ScienceDaily

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
- ScienceDaily
- 21/3/5 19:37
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.
Going forth with standardized tests may cause more problems than it solves
Despite the many ways that COVID-19 has disrupted schools, the U.S. Department of Education will not give states a pass on giving standardized tests to students this year as it did in spring 2020. That's according to new guidance the department issued Feb. 22.
'Canada's leading ecologist': David Schindler dead at 80
David Schindler, the renowned ecologist known for his outspoken defence of Canada's freshwater systems from industrial harm, is dead. He was 80.
Food security: Irradiation and essential oil vapors for cereal treatment
A combined treatment of irradiation and essential oil vapors could effectively destroy insects, bacteria and mold in stored grains. A team from the Institut national de la recherche scientifique (INRS), led by Professor Monique Lacroix, has demonstrated the effect of this process on insects affecting rice. The study was published in Radiation Physics and Chemistry.
'I want to ride my bicycle!' People set to change mobility choices post-lockdown
New research suggests a significant proportion of Trinity's staff and student population that formerly relied on public transport will now choose to walk or cycle to campus when it fully re-opens after lockdown.
Tantalizing signs of phase-change 'turbulence' in RHIC collisions
Physicists studying collisions of gold ions at the Relativistic Heavy Ion Collider (RHIC), a U.S. Department of Energy Office of Science user facility for nuclear physics research at DOE's Brookhaven National Laboratory, are embarking on a journey through the phases of nuclear matter—the stuff that makes up the nuclei of all the visible matter in our universe. A new analysis of collisions...
Making sense of commotion under the ocean to locate tremors near deep-sea faults
Researchers from Japan and Indonesia have pioneered a new method for more accurately estimating the source of weak ground vibrations in areas where one tectonic plate is sliding under another in the sea. Applying the approach to Japan's Nankai Trough, the researchers were able to estimate previously unknown properties in the region, demonstrating the method's promise to help probe properties...
Ecosystem services: Species are our livelihoods
Functioning ecosystems provide the basis for security, basic material needs, health, social interaction and individual liberty. This is how the Millennium Ecosystem Assessment 2005 described it, dividing ecosystem services into the following categories: The provisioning services; goods such as food, water, firewood and timber, the regulating services; pollination, water filtering function of the...
Engineering marvel: Sixth mirror cast for Giant Magellan Telescope
The Giant Magellan Telescope announces fabrication of the sixth of seven of the world's largest monolithic mirrors. These mirrors will allow astronomers to see farther into the universe with more detail than any other optical telescope before. The sixth 8.4-meter (27.5 feet) mirror—about two stories high when standing on edge—is being fabricated at the University of Arizona's Richard F. Caris...
Life's rich pattern: Researchers use sound to shape the future of printing
Researchers in the UK 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.
Eight ways chemical pollutants harm the body
- ScienceDaily
- 21/3/5 18:38
A new review of existing evidence proposes eight hallmarks of environmental exposures that chart the biological pathways through which pollutants contribute to disease: oxidative stress and inflammation, genomic alterations and mutations, epigenetic alterations, mitochondrial dysfunction, endocrine disruption, altered intercellular communication, altered microbiome communities, and impaired...
After old age, intellectual disability is greatest risk factor for death from COVID-19, study finds
- ScienceDaily
- 21/3/5 18:38
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
- ScienceDaily
- 21/3/5 18:38
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
- ScienceDaily
- 21/3/5 18:38
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.
Huntington's disease driven by slowed protein-building machinery in cells
- ScienceDaily
- 21/3/5 18:38
The gene for Huntington's disease was found nearly 40 years ago, yet there are no approved treatments. A new study shows the problem may lie with slowed protein assembly.
Tantalizing signs of phase-change 'turbulence' in RHIC collisions
- ScienceDaily
- 21/3/5 18:37
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...

What can stream quality tell us about quality of life?
As the source of most of the water we drink and a place where we often go to recreate and enjoy nature, streams represent a crucial point-of-contact between human beings and the environment.
Sports information on social networks leaves out women, disabled and minority disciplines
Researchers from the University of Seville and Pompeu Fabra University argue that sports information on social media is dominated by men and football. This leaves out women's sports, sports featuring athletes with disabilities and minority disciplines, thus repeating the reality of the traditional media. That is the main conclusion of a study analyzing more than 7,000 tweets published by the...
