A new system developed by chemical engineers at MIT could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively little energy.
People with multiple sclerosis (MS) gradually develop increasing functional impairment. Researchers at Karolinska Institutet have now found a possible explanation for the progressive course of the disease in mice and how it can be reversed. The study, which is published in Science Immunology, can prove valuable to future treatments.
MS is a chronic inflammatory disease of the central nervous system (CNS) and one of the main causes of neurological functional impairment.
A new study coordinated by CU Boulder makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as the Anthropocene. Distinct physical, chemical and biological changes to Earth's rock layers began around the year 1950, the research found.
Climate change caused by emissions of greenhouse gases into the atmosphere is a most important issue for our society. Acceleration of global warming results in catastrophic heatwaves, wildfires, storms and flooding. The anthropogenic nature of climate change necessitates development of novel technological solutions in order to reverse the current CO2 trajectory.
Mental health problems such as Post-Traumatic Stress Disorder, anxiety and depression are common among healthcare staff during and immediately after pandemics - according to new research from the University of East Anglia.
Researchers investigated how treating patients in past pandemics such as SARS and MERS affected the mental health of front-line staff.
Unhealthy behaviours trigger moral judgments that are similar to the basic emotions that contribute to our ability to survive. Two different hypotheses are to be found in the current scientific literature as to the identity of these emotions. Some researchers single out disgust, while others opt for pain. After developing a new approach to brain imaging, a research team from the University of Geneva (UNIGE) has come down on the side of disgust.
We are all taught at high school that the speed of light through a vacuum is about 300000 km/s, which means that a beam from Earth takes about 2.5 seconds to reach the Moon. It naturally moves more slowly through transparent objects, however, and scientists have found ways to slow it dramatically. Optomechanics, or the interaction of electromagnetic radiation with mechanical systems, is a relatively new and effective way of approaching this.
To contribute to global climate protection, Germany has to rapidly and comprehensively minimize the use of fossil energy sources and to transform the energy system accordingly. The Helmholtz Association's research initiative "Energy System 2050" has studied how and by which means this can be achieved. One of the partners is Karlsruhe Institute of Technology (KIT). At the final conference in Berlin, scientists of the participating research centers presented their results.
TAMPA, Fla. -- Personalized treatment options for patients with lung cancer have come a long way in the past two decades. For patients with non-small cell lung cancer, the most common subtype of lung cancer and the leading cause of cancer-related death worldwide, two major treatment strategies have emerged: tyrosine kinase inhibitors and immune checkpoint inhibitors. However, choosing the right therapy for a non-small cell lung cancer patient isn't always an easy decision, as biomarkers can change during therapy rendering that treatment ineffective.
WASHINGTON - A peer-reviewed study by scientists at the Environmental Working Group estimates that more than 200 million Americans could have the toxic fluorinated chemicals known as PFAS in their drinking water at a concentration of 1 part per trillion, or ppt, or higher. Independent scientific studies have recommended a safe level for PFAS in drinking water of 1 ppt, a standard that is endorsed by EWG.
A team of researchers have examined whether urban red maples - a resilient native tree known to thrive in urban environments - acclimate to environmental shifts and whether that response is impacted by the size of the city.
They found that trees in larger cities are actually healthier and more productive than those in less dense areas.
In this year of extreme weather events -- from devastating West Coast wildfires to tropical Atlantic storms that have exhausted the alphabet -- scientists and members of the public are asking when these extreme events can be scientifically linked to climate change.
Dale Durran, a professor of atmospheric sciences at the University of Washington, argues that climate science need to approach this question in a way similar to how weather forecasters issue warnings for hazardous weather.
UNIVERSITY PARK, Pa. -- Allegiance and loyalty to your country is highly valued in America, but what if you feel America doesn't love you back? New research examined whether feeling like you belong in America -- or not -- affected how members of different races and ethnicities participated in politics.
Ray Block Jr., associate professor of political science and African American studies at Penn State, said the study suggests that people who don't embody a typical white American identity may have complicated feelings of Americanness that may also affect their politics.
Scientists from NASA's Goddard Space Flight Center in Greenbelt, Maryland, and international collaborators demonstrated a new method for mapping the location and size of trees growing outside of forests, discovering billions of trees in arid and semi-arid regions and laying the groundwork for more accurate global measurement of carbon storage on land.
University of New Mexico researchers who combed through a "library" of previously approved drugs believe they have identified a medication with the potential to help speed a patient's recovery from SARS-CoV-2 infection.
