The key to lowering CO2 emissions is made of metal

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.

Driving behavior less 'robotic' thanks to new model

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'.

Senescent cells may be good when it comes to a bad injury

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.

Plant droplets serve as nutrient-rich food for insects

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.

Cannabis data lacking, but machine learning could help

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.

Discovery enables adult skin to regenerate like a newborn's

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...

Second alignment plane of solar system discovered

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...

Filtering radioactive elements from water

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.

Biodiversity: 'Cool' sampling sites more likely to show false trends

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...

Forgetting past misdeeds to justify future ones

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...

Successful TB vaccine moves forward after phase 2 trial

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.
