Scientists investigating ways of removing carbon dioxide (CO2) and other greenhouse gases from our atmosphere believe volcanic ash could play an important role.
A 10-year effort by China to improve air quality and reduce pollution-related health risks has caused warming in areas across the northern hemisphere, according to new work.
Hybrid systems of floating solar panels and hydropower plants may hold the technical potential to produce a significant portion of the electricity generated annually across the globe, according to a new analysis.
Researchers produce malic acid, which contains 4 carbon atoms, through artificial photosynthesis by simply adding metal ions like aluminum and iron. This solves a problem with current artificial photosynthesis technology of only producing molecules with 1 carbon atom and paves the way to exploring the use of CO2 as a raw material.
Researchers have now developed a new model that describes driving behavior on the basis of one underlying 'human' principle: managing the risk below a threshold level. This model can accurately predict human behavior during a wide range of driving tasks. In time, the model could be used in intelligent cars, to make them feel less 'robotic'.
Two and a half years ago, MIT entered into a research agreement with startup company Commonwealth Fusion Systems to develop a next-generation fusion research experiment, called SPARC, as a precursor to a practical, emissions-free power plant.
It's called senescence, when stressed cells can no longer divide to make new cells, and it's considered a factor in aging and in some diseases. Now scientists have some of the first evidence that at a younger age at least, senescent cells show up quickly after a major injury and are protective.
Small watery droplets on the edges of blueberry bush leaves are loaded with nutrients for many insects, including bees, wasps and flies, according to a new study, the first of its kind. The study suggests that these droplets are an important but underexplored feature in plants, with profound implications for insects in agricultural and natural ecosystems.
Extracurricular sport in middle childhood diminishes subsequent ADHD symptoms in girls, but not in boys, a new study suggests.
Everyone's heard of THC and CBD. But many other active compounds in cannabis interact to influence its effects. A new study confirms that those compounds are seldom tested for, and strain name is not indicative of potency or chemical makeup. Machine learning techniques could help fill the knowledge gap.
A new clothing-like exoskeleton can reduce back muscle fatigue and providing needed physical relief to material handlers, medical professionals and frontline workers.
A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn. The discovery has implications for wound treatment and preventing some of the aging process in skin. Researchers identified a factor in the skin of baby mice controlling hair follicle formation. When it was activated in adult mice, their skin was able to heal wounds without scarring. The reformed skin...
A new study provides evidence that the seasonal colds you've had in the past could protect you from COVID-19. The study also suggests that immunity to COVID-19 is likely to last a long time -- maybe even a lifetime.
A gene that helps to control inflammation increases the risk of obesity and could be turned off in mice to stop weight gain, a study has found.
Loved or hated, the humble oat could be the new superfood for cancer patients as international research shows a diet rich in fibre could significantly reduce radiation-induced gut inflammation.
Climate warming will alter marine community compositions as species are expected to shift poleward, significantly impacting the Arctic marine ecosystem.
A study of comet motions indicates that the Solar System has a second alignment plane. Analytical investigation of the orbits of long-period comets shows that the aphelia of the comets, the point where they are farthest from the Sun, tend to fall close to either the well-known ecliptic plane where the planets reside or a newly discovered 'empty ecliptic.' This has important implications for models...
Scientists have measured the molecular footprint that aging leaves on various mouse and human tissues. Using the data, they have identified likely regulators of this central process.
Some people are at higher risk of developing obesity because they possess genetic variants that affect how the brain processes sensory information and regulates feeding and behavior. The findings support a growing body of evidence that obesity is a disease whose roots are in the brain.
Researchers previously developed a filter membrane made out of whey proteins and activated carbon. In a new study, they now demonstrate just how efficient this membrane is at filtering radioactive elements from contaminated water.
Researchers have found a way to produce miniaturized antibodies, opening the way for a potential new class of treatments for diseases.
New research suggests the planting of more trees could have a significant and positive effect in preventing flash flooding.
Data collected by citizen science initiatives, museums and national parks is an important basis for research on biodiversity change. However, scientists found that sampling sites are oftentimes not representative, which may lead to false conclusions about how biodiversity changes. Their research calls for more objective site selection and better training for citizen scientists to prevent a...
Proven fact: we remember our altruistic behavior more easily than selfish actions or misdeeds that go against our own moral sense. Described as 'unethical amnesia' by scientists, it is generally explained by self-image maintenance. But could these selective oversights, not necessarily conscious, have a more strategic aim? To find out, a team of behavioral economists recruited 1322 volunteers in an...
Results from the Phase 2 trial of the DAR-901 tuberculosis (TB) vaccine were announced today. The three-year trial was conducted among 650 adolescents in Tanzania, a nation with high rates of TB infection, and showed that the vaccine was safe and induced immune responses against the disease.
