Oldest documented site of indiscriminate mass killing Posted: 10 Mar 2021 12:04 PM PST DNA, archaeological and skeletal evidence demonstrates an indiscriminate massacre and haphazard burial of 41 individuals from an early pastoralist community in what is now eastern Croatia 6,200 years ago.

Scythian people weren't just nomadic warriors, but sometimes settled down Posted: 10 Mar 2021 12:04 PM PST New research finds that Scythian people of ancient Ukraine led more complex lives than commonly assumed.

High rates of depression, anxiety, PTSD worldwide among health workers during COVID-19 Posted: 10 Mar 2021 12:04 PM PST A new systematic review of 65 studies from around the world involves a total of 97,333 health care workers and finds that one in five have experienced depression, anxiety, and/or PTSD during the ongoing COVID-19 pandemic.

'Lost' ocean nanoplastic might be getting trapped on coasts Posted: 10 Mar 2021 10:23 AM PST As plastic debris weathers in aquatic environments, it can shed tiny nanoplastics. Although scientists have a good understanding of how these particles form, they still don't have a good grasp of where all the fragments end up. Now, researchers have shown experimentally that most nanoplastics in estuarine waters can clump, forming larger clusters that either settle or stick to solid objects, instead of floating on into the ocean.

Robots can use eye contact to draw out reluctant participants in groups Posted: 10 Mar 2021 09:26 AM PST Researchers published results of experiments in which robots led a Swedish word game with individuals whose proficiency in the Nordic language was varied. They found that by redirecting its gaze to less proficient players, a robot can elicit involvement from even the most reluctant participants.

Venom-extraction and exotic pet trade may hasten the extinction of scorpions Posted: 10 Mar 2021 09:26 AM PST Sustainably produced scorpion venoms are important, for example, in the pharmacological industry. However, in the recent years, there has been a dramatic increase in the number of people involved in the trade and vast numbers of scorpions are harvested from nature. This development is endangering the future of several scorpion species in a number of areas.

Quantum physicists measure the smallest gravitational force yet Posted: 10 Mar 2021 09:26 AM PST Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment opens up new possibilities for testing the laws of gravity on previously unattained small scales.

Daily e-cigarette use shows 'clear benefit' in helping smokers to quit, study finds Posted: 10 Mar 2021 09:26 AM PST New research shows that when used daily, e-cigarettes can help people to quit smoking, compared to no help at all.

An electrically charged glass display smoothly transitions between a spectrum of colors Posted: 10 Mar 2021 09:25 AM PST Scientists have developed a see-through glass display with a high white light contrast ratio that smoothly transitions between a broad spectrum of colors when electrically charged. The technology overcomes limitations of existing electrochromic devices by harnessing interactions between metal ions and ligands, opening the door for numerous future applications.

Researchers develop guidelines for reporting polygenic risk scores Posted: 10 Mar 2021 09:25 AM PST Scientists and healthcare providers are beginning to use polygenic risk scores for assessing a person's inherited risk for common complex diseases. But researchers have observed inconsistencies in how such scores are calculated and reported. To address this concern, researchers have published a framework that identifies the minimal polygenic risk score-related information that scientists should include in their studies.

Long-accepted theory of vertebrate origin upended by fossilized lamprey larvae Posted: 10 Mar 2021 09:25 AM PST A study of fossilized lampreys dating from more than 300 million years ago is challenging a long-held theory about the evolutionary origin of vertebrates. These ancient, jawless, eel-like fishes arose around half a billion years ago and they have long provided insights into vertebrate evolution. The analysis of the fossils counters the established view that the blind, filter-feeding larvae of modern lampreys (ammocoetes) are a holdover from the ancestors of living vertebrates.

IceCube detection of high-energy particle proves 60-year-old physics theory Posted: 10 Mar 2021 09:25 AM PST On December 6, 2016, a high-energy particle hurtled to Earth from outer space at close to the speed of light. It triggered the sensors of the IceCube Neutrino Observatory, a massive telescope buried in the Antarctic glacier. IceCube had seen a Glashow resonance event, a phenomenon predicted by Nobel laureate physicist Sheldon Glashow in 1960.

Placenta is a dumping ground for genetic defects Posted: 10 Mar 2021 09:25 AM PST The first study of the genomic architecture of the human placenta confirms that the normal structure of the placenta is different to any other human organ and resembles that of a tumor, harboring many of the same genetic mutations found in childhood cancers.

Variant B.1.1.7 of COVID-19 associated with a significantly higher mortality rate, research shows Posted: 10 Mar 2021 09:24 AM PST A new study finds that the highly infectious B.1.1.7 variant of COVID-19, which swept across the UK last year before spreading worldwide, is between 30 and 100 per cent more deadly than previous strains.

Face masks and the environment: Preventing the next plastic problem Posted: 10 Mar 2021 09:24 AM PST Every minute of the day we throw away 3 million face masks. Many end up as potentially toxic micro- and nanoplastic or carriers for other toxicants in the environment, researchers warn.

Extracting information from ancient teeth Posted: 10 Mar 2021 09:23 AM PST There's a surprising amount of information stored in the hardened plaque, or calculus, between teeth. And if that calculus belongs to the remains of a person who lived in ancient times, the information could reveal new insights about the past. But the tiny samples can be difficult to work with. Now, scientists apply a new method to this analysis, finding more proteins than traditional approaches.

Using artificial intelligence to generate 3D holograms in real-time Posted: 10 Mar 2021 09:19 AM PST Researchers have developed a way to produce holograms almost instantly. The deep learning-based method is so efficient, it could run on a smartphone, they say.

Successful trial shows way forward on quieter drone propellers Posted: 10 Mar 2021 07:06 AM PST Researchers have published a study revealing their successful approach to designing much quieter propellers.

New lung cancer screening recommendation, starting at age 50, expands access but may not address inequities Posted: 10 Mar 2021 05:48 AM PST Calling the US Preventive Services Task Force's newly released recommendation statement to expand eligibility for annual lung cancer screening with low-dose computed tomography a step forward, researchers say future changes should address equity and implementation issues.

Evidence review examines both benefits and harms for lung cancer screening Posted: 10 Mar 2021 05:47 AM PST A comprehensive review shows there are both benefits and harms from screening.

Carbon nanotube patterns called moirés created for materials research Posted: 10 Mar 2021 05:47 AM PST Material behaviors depend on many things including not just the composition of the material but also the arrangement of its molecular parts. For the first time, researchers have found a way to coax carbon nanotubes into creating moiré patterns. Such structures could be useful in materials research, in particular in the field of superconducting materials.

Avatar marketing: Moving beyond gimmicks to results Posted: 10 Mar 2021 05:47 AM PST Aligning the form realism and behavioral realism of avatars is important for successful marketing applications.

Huge potential for electronic textiles made with new cellulose thread Posted: 10 Mar 2021 05:47 AM PST Electronic textiles offer revolutionary new opportunities in various fields, in particular healthcare. But to be sustainable, they need to be made of renewable materials. A research team now presents a thread made of conductive cellulose, which offers fascinating and practical possibilities for electronic textiles.

Solar Cells: The mystery of the missing energy - solved Posted: 10 Mar 2021 05:47 AM PST The efficiency of solar cells can be increased by exploiting a phenomenon known as singlet fission. However, unexplained energy losses during the reaction have until now been a major problem. Scientists have now discovered what happens during singlet fission and where the 'lost' energy goes.
