- 20/9/29 21:21
Researchers studying interferons, immune response proteins released naturally by human cells when viruses are detected, have uncovered new details on the mechanisms underlying cell defenses. They describe the intricate, time-dependent regulatory mechanisms that human cells use to control the duration and strength of antiviral responses triggered by interferon. Based on these findings, researchers...

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.
The key to lowering CO2 emissions is made of metal
- ScienceDaily
- 20/9/29 18:36
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
- ScienceDaily
- 20/9/29 18:35
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'.
Validating the physics behind the new fusion experiment
- ScienceDaily
- 20/9/29 18:35
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.
Senescent cells may be good when it comes to a bad injury
- ScienceDaily
- 20/9/29 18:35
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
- ScienceDaily
- 20/9/29 18:35
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.
Girls benefit from doing sports
- ScienceDaily
- 20/9/29 18:35
Extracurricular sport in middle childhood diminishes subsequent ADHD symptoms in girls, but not in boys, a new study suggests.
Cannabis data lacking, but machine learning could help
- ScienceDaily
- 20/9/29 18:35
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.
Wearable exosuit that lessens muscle fatigue could redesign the future of work
- ScienceDaily
- 20/9/29 18:35
A new clothing-like exoskeleton can reduce back muscle fatigue and providing needed physical relief to material handlers, medical professionals and frontline workers.
Discovery enables adult skin to regenerate like a newborn's
- ScienceDaily
- 20/9/29 18:35
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...

- 20/9/29 18:34
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...
