Point-of-Care UltraSonography deployed during the emergency treatment of patients with acute dyspnea has enormous advantages over standard diagnostic pathways. This is the finding of a joint review conducted by Danube University Krems and MedUni Vienna and recently published in the prestigious Annals of Internal Medicine. It allows serious conditions to be identified more quickly so that appropriate treatment can be initiated.

An international team of researchers led by Osaka University came closer to unraveling the complicated optical response of wide-bandgap semiconductor multiple quantum wells and how atomic-scale lattice vibration can generate free space terahertz emission. Their work provides a significant push towards the application of laser terahertz emission microscopes to nano-seismology of wide-bandgap quantum devices

The morphological compatibility between flowers and insects was given in the famous textbook example of Darwin's orchids and hawkmoths. As in this example, many studies have shown that geographical variations in flower size match the size of insects in each region. In other words, studies have shown "flower-sized regional adaptation" in which large flowers evolve in areas pollinated by large insects and small flowers evolve in areas pollinated by small insects.

How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails. A research team at TU Wien (Vienna) has now been able to simulate this process on the computer.

A neurologic pathway by which non-damaging but high frequency brain impact blunts normal brain function and causes long-term problems with learning and memory has been identified. The finding suggests that tailored drug therapy can be designed and developed to reactivate and normalize cognitive function, say neuroscientists at Georgetown University Medical Center.

Blocking the fat-busting enzyme lipoxygenase with a synthetic inhibitor throws the immune system's innate inflammatory response out of whack, compromising cardiac repair during acute heart failure. The preclinical study by University of South Florida Health researchers helps explain one more piece of the puzzle about the important role of immune-mediated acute inflammation and its clearance - both in promoting cardiac health and stopping the progression of heart failure.

Watching meaningful films - those that we find moving and poignant - can make us feel more prepared to deal with life's challenges and want to be a better person, a new study found.The findings point to one reason why people may choose to see movies that make them sad as well as happy and that may explore difficult subjects that aren't always uplifting.

Chinese researchers achieved 51.5dB nonreciprocal isolation in the atomic ensemble, which is the highest isolation ratio in the non-magnetic nonreciprocal field.

A research team led by Prof. LI Chuanfeng and Prof. ZHOU Zongquan from University of Science and Technology of China extended the storage time of the optical memories to over one hour. It broke the record of one minute achieved by German researchers in 2013, and made a great stride towards the application of quantum memories.

An international team led by researchers from the Xinjiang Institute of Ecology and Geography (XIEG) of the Chinese Academy of Sciences and the University of Geneva has found that flash floods may triple across the Earth's "Third Pole" in response to ongoing climate change.

Computer scientists at the University of California San Diego have developed a more accurate navigation system that will allow robots to better negotiate busy clinical environments in general and emergency departments more specifically. The researchers have also developed a dataset of open source videos to help train robotic navigation systems in the future. The team detail their findings in a paper for the International Conference on Robotics and Automation taking place May 30 to June 5, 2021 in Xi'an, China.

A new study indicates São Tomé island has two species of caecilians found nowhere else on Earth. The research adds evidence to a century-long scientific debate and reveals how volcanic activity may have driven the divergence of the limbless amphibians.

A new system developed in the lab of Zhen (Jason) He uses bacteria to filter wastewater while creating electricity.

End-of-life circuit boards, certain magnets in disc drives and electric vehicles, EV and other special battery types, and fluorescent lamps are among several electrical and electronic products containing critical raw materials (CRMs), the recycling of which should be made law, says a new UN-backed report funded by the EU.

Modeling shows fluctuating soil microbial populations impact how much carbon is released from soil.

Researchers at Linköping University, Sweden, have made several discoveries on the functioning mechanisms of the inner hair cells of the ear, which convert sounds into nerve signals that are processed in the brain. The results, presented in the scientific journal Nature Communications, challenge the current picture of the anatomical organisation and workings of the hearing organ, which has prevailed for decades.

A research group led by Dr. Hideyuki Kobayashi at Toho University Omori Medical Center in Tokyo developed an AI-assisted image classifier that provides scores for histological testis images of patients with azoospermia. The objective of Dr. Kobayashi, a urologist, was to create an easy-to-use method of pathological examination for the daily clinical practice setting. With it, testis images could be classified at 82.6% accuracy.

Researchers at the IST Austria led by Björn Hof reports that a small difference in epidemic mitigation levels can cause a discontinuous jump in infection numbers. The researchers show that limits in testing and contact tracing are responsible for this sudden change in the epidemic outcome. Testing followed up by contact tracing is extremely efficient in slowing down epidemics, however, once their limit is exceeded the epidemic accelerates resulting in a faster than exponential spread.

Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells. A brain imaging study at Karolinska Institutet now shows that the average level of the serotonin transporter increased in a group of 17 individuals who recovered from depression after cognitive behavioural therapy. The results are published in the journal Translational Psychiatry.

In a small study, 82% of the college athletes with COVID-19 had symptoms, of which the majority were mild and did not require treatment.Further screening via cardiac MRI of the 4% of athletes identified with heart abnormalities found no heart damage or inflammation.All athletes resumed regular training and competition without difficulty after recovering from COVID-19.
