Prediction tool shows how forest thinning may increase Sierra Nevada snowpack
- ScienceDaily
- 20/5/7 22:40
Thinning the Sierra Nevada forest by removing trees by hand or using heavy machinery is one of the few tools available to manage forests. However, finding the best way to thin forests by removing select trees to maximize the forest's benefits for water quantity, water quality, wildfire risk and wildlife habitat remains a challenge for resource managers.

Physicists shed light on the nanoscale dynamics of spin thermalization
- ScienceDaily
- 20/5/7 22:39
In physics, thermalization, or the trend of sub-systems within a whole to gain a common temperature, is typically the norm. There are situations, however, where thermalization is slowed down or virtually suppressed; examples are when considering the dynamics of electron and nuclear spins in solids. Understanding why this happens and how it can be controlled is presently at the center of a broad...
Laser loop couples quantum systems over a distance
- ScienceDaily
- 20/5/7 20:30
For the first time, researchers have succeeded in creating strong coupling between quantum systems over a greater distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly lossless exchange of information and strong interaction between them. The physicists reported that the new method opens up new possibilities in quantum networks and quantum...

- 20/5/7 20:30
A restoration ecologist has a simple message for anyone who thinks planting 1 trillion trees will reverse the damage of climate change: 'We can't plant our way out of climate change.'
Immunity of recovered COVID-19 patients could cut risk of expanding economic activity
- ScienceDaily
- 20/5/7 19:53
New modeling of coronavirus behavior suggests that an intervention strategy based on shield immunity could reduce the risk of allowing the higher levels of human interaction needed to support expanded economic activity.
Light, sound, action: Extending the life of acoustic waves on microchips
- ScienceDaily
- 20/5/7 19:13
Data centres and digital information processors are reaching their capacity limits and producing heat. Foundational work here on optical-acoustic microchips opens door to low-heat, low-energy, fast internet.
Lipid metabolism controls brain development
- ScienceDaily
- 20/5/7 19:13
A lipid metabolism enzyme controls brain stem cell activity and lifelong brain development. If the enzyme does not work correctly, it causes learning and memory deficits in humans and mice, as researchers have discovered. Regulating stem cell activity via lipid metabolism could lead to new treatments for brain diseases.
A role reversal for the function of certain circadian network neurons
- ScienceDaily
- 20/5/7 19:13
A new study y reveals surprising findings about the function of circadian network neurons that undergo daily structural change. The research could lead to a better understanding of how to address circadian rhythm disruptions in humans and facilitate preventing a host of associated health problems, including increased risk for cancer and metabolic syndrome.
Virgin birth has scientists buzzing

A radar for plastic: High-resolution map of 1 kilometer grids to track plastic emissions in seas
- ScienceDaily
- 20/5/7 19:13
Plastic waste often ends up in river bodies and oceans, posing a serious threat to the marine ecosystem. To prevent the accumulation of plastic debris, we must find out where plastic emission is prevalent. To this end, scientists have come up with a new method to track plastic emissions from inland areas to sea. This method is useful to identify the ''hotspots'' of plastic emission and can even...
The feeling a limb doesn't belong is linked to lack of brain structure and connection
- ScienceDaily
- 20/5/7 19:13
People with body integrity dysphoria (BID) often feel as though one of their healthy limbs isn't meant to be a part of their bodies. They may act as though the limb is missing or even seek its amputation 'to feel complete.' Now, researchers have found that these feelings that a limb doesn't belong are mirrored in the brains of people with this condition.
