Engineers have developed a device that uses sound waves to separate and sort the tiniest particles found in blood, in a matter of minutes. The technology is based on a concept called 'virtual pillars' and could be a boon to both scientific research and medical applications.
Kibble-Zurek mechanism for nonequilibrium phase transitions
- ScienceDaily
- 22/12/2 20:25
The Kibble-Zurek (KZ) mechanism, confirmed experimentally only for equilibrium phase transitions, is also applicable for non-equilibrium phase transitions, as is now shown in a landmark study. The KZ mechanism is characterized by the formation of topological defects during continuous phase transition away from the adiabatic limit. This breakthrough finding could open the doors to investigation of...

Health benefits of using wind energy instead of fossil fuels
- ScienceDaily
- 22/12/2 20:25
A new study finds that the health benefits associated with wind power could more than quadruple if operators turned down output from the most polluting fossil-fuel-based power plants when energy from wind is available. However, compared to wealthier communities, disadvantaged communities would reap a smaller share of these benefits.

Researchers have applied emerging electronic tattoo (e-tattoo) technology to the tricky task of measuring stress levels by attaching a device to people's palms.
Pregnant moms' stress may accelerate cell aging of white, not Black, kids, study finds
- ScienceDaily
- 22/12/2 18:48
Does stress during pregnancy impact children's cell aging, and does race matter? The answer is yes, according to a new study.
Common immune cells can prevent intestinal healing
- ScienceDaily
- 22/12/2 17:25
B cells are critical to the proper functioning of the immune system. However, researchers have shown that they can sometimes do more harm than good, as their numbers greatly increase after bowel damage, preventing the tissue from healing. The results can be of significance to the treatment of inflammatory bowel disease.
Synchronized neural oscillations in the right brain induce empathic behavior
- ScienceDaily
- 22/12/2 17:25
A research team has discovered the underlying neural mechanism that allows us to feel empathy. The group's study on mice hinted that empathy is induced by the synchronized neural oscillations in the right hemisphere of the brain, which allows the animals to perceive and share each other's fear.

As the Christmas season starts to ramp up, researchers are reminding people to prioritize a good night's sleep as new research shows that a troubled sleep may be associated with risk factors for type 2 diabetes.
Adults living in areas with high air pollution are more likely to have multiple long-term health conditions
- ScienceDaily
- 22/12/2 17:25
Exposure to traffic related air pollution is associated with an increased likelihood of having multiple long-term physical and mental health conditions according to a new study of more than 364,000 people in England.
Purchasing loot boxes in video games associated with problem gambling risk, says study
- ScienceDaily

Gamers who buy 'loot boxes' are up to two times more likely to gamble, shows new research.
Study reveals extent of residual lung damage after COVID-19 hospitalization
- ScienceDaily
- 22/12/2 17:25
In a new study, researchers sought to determine the percentage of COVID-19 patients discharged from the hospital who had a type of fibrotic lung damage, known as interstitial lung disease, that requires ongoing follow-up care. These patients had varying degrees of COVID-19 severity at hospital admission.
Large band bending at SnS interface opens door for highly efficient thin-film solar cells
- ScienceDaily
- 22/12/2 17:25
Tin sulfide (SnS) solar cells have shown immense promise in the rush to develop more environmentally friendly thin-film solar cells. Yet for years SnS solar cells have struggled to achieve a high conversion efficiency. To overcome this, a SnS interface exhibiting large band bending was necessary, something a research group has recently achieved.
Batteryless and wireless device detects coronavirus with magnetostrictive composite plates
- ScienceDaily
- 22/12/2 17:25
What if you could tell if your surroundings contained COVID-19 particles or droplets the moment they or you entered the vicinity? This is now closer to reality. Researchers have engineered a battery-less, self-powering device that can wirelessly transmit the detection of coronavirus in the air.
Cheetah marking trees are hotspots for communication also for other species
- ScienceDaily
- 22/12/2 17:25
Marking trees are important hotspots of communication for cheetahs: Here they exchange information with and about other cheetahs via scent marks, urine and scats. A team has now shown that several mammalian species on farmland in Namibia maintain a network for intra- and interspecific communication at cheetah trees. Black-backed jackals, African wildcats and warthogs visited and sniffed the...
Microplastics could make other pollutants more harmful
- ScienceDaily
- 22/12/2 17:24
Microplastics -- small plastic pieces less than five millimeters in length -- are becoming a ubiquitous ecological contaminant. Studies suggest that on their own, these tiny bits are potentially harmful, and it's unclear what effect they could have on pollutants that latch onto them. Now, researchers show that, when attached to microplastics, UV filters used in products such as sunscreens can make...
