A team of researchers from Politecnico di Milano, the University of California and Massey University has created maps of possible hotspots in Asia and Europe where the risk of coronaviruses jumping from bats to humans is highest. In their paper published in the journal Nature Food, the researchers describe how they combined data regarding human population densities, horseshoe bats, land use and other factors to create their maps and what they showed. Monia Santini, with Foundation Euro-Mediterranean Center on Climate Change... Читать дальше...

A team of researchers at the University of Cambridge has found that Eurasian jays are less likely than people to be deceived by well-known magic tricks. In their paper published in Proceedings of the National Academy of Sciences, the group describes their motivation for testing birds with magic tricks and what they learned by doing so.

Parkinson's disease (PD) is a common neurodegenerative disorder caused by the death of dopaminergic neurons in a part of the brain (known as substantia nigra pars compacta), which leads to a deficit of dopamine (DA), one of the main neurotransmitters active in the central nervous system. Symptomatic treatment focuses on increasing the concentration of dopamine into the brain.

Research by scientists from University of Southampton (UK) and the Central University of Jharkhand (India) has shown the first COVID-19 lockdown in India led to an improvement in air quality and a reduction in land surface temperature in major urban areas across the country.

The inclusion of Māori and other Indigenous philosophies in the conservation management of Antarctica is the theme of an article co-written by Māori philosopher Associate Professor Krushil Watene.

A team of researchers at Osaka University, together with Rediscovery of the wheel Inc., and JFE Shoji Electronics Corporation, has developed an ultra-wideband radar system, which can be mounted on drones. With the cooperation of the Tokuyama Plant of Idemitsu Kosan Co., Ltd., a drone equipped with the radar was flown in a chimney with a height of 150 m during a regular inspection period (Fig. 1). The researchers have succeeded in inspecting the thickness of the lining material, which covers the chimney wall as a protection layer.

In a new report now published on Science Advances, Mingfei Xiao and a team of interdisciplinary and international scientists in the U.K., Saudi Arabia, Australia, India, China and Belgium, investigated the charge transport physics of a previously unidentified class of conjugated polymers. Such polymers are expected to behave as rigid rods, however, not much is known of their actual chain conformation and electronic structure. In this work, Xiao et al. detailed a study of the structural and charge... Читать дальше...

In "Atchafalaya," John McPhee's essay in the 1989 book "The Control of Nature," the author chronicles efforts by the U.S. Army Corps of Engineers to prevent the Atchafalaya River from changing the course of the Mississippi River where they diverge, due to the Atchafalaya's steeper gradient and more direct route to the gulf. McPhee's classic essay proved inspirational to John Shaw, an assistant professor of geosciences who called it "a foundational text."

Global oceans absorb about 25% of the carbon dioxide released into the atmosphere when fossil fuels are burned. Electricity-eating bacteria known as photoferrotrophs could provide a boost to this essential process, according to new research from Washington University in St. Louis.

Researchers at DTU Health Tech have developed a new material that can facilitate a near-perfect merger between machines and the human body for diagnostics and treatment.

Hidden beneath a kilometer of ice in northwestern Greenland, an impact crater that could swallow a city the size of London, Ont. is the subject of much debate about its origins and age.

Swedish researchers from institutions including Uppsala University have spent four years gathering data from the areas affected by the major forest fire of 2014. In their study of how the ecosystem as a whole has been altered, they could see that water quality in watercourses quickly returned to normal, while forested areas continued to lose carbon for many years after the fire.

In the deep waters that underlie the productive zones of the ocean, there is a constant rain of organic material called "marine snow." Marine snow does not only look like real snow but also behaves similarly: Large flakes are rare and fall quickly while highly abundant smaller flakes take their time. Scientists from Bremen and Kiel have now discovered that precisely those features explain why small particles play an important role for the nutrient balance of the oceans. These findings have now been... Читать дальше...

As our climate warms, ice melting from glaciers around the world is one of main causes of sea-level rise. As well as being a major contributor to this worrying trend, the loss of glacier ice also poses a direct threat to hundreds of millions of people relying on glacier runoff for drinking water and irrigation. With monitoring mountain glaciers clearly important for these reasons and more, new research, based on information from ESA's CryoSat mission, shows how much ice has been lost from mountain...

Despite the tragic deaths, suffering and sadness that it has caused, the pandemic could go down in history as the event that rescued humanity. It has created a once-in-a-generation opportunity to reset our lives and societies onto a sustainable path. Global surveys and protests have demonstrated the appetite for fresh thinking and a desire not to return to the pre-pandemic world.

The wildfire season in western North America keeps setting new records and the outlook for the coming summer seems grim.

Using the 4-meter Blanco telescope at the Cerro Tololo InterAmerican Observatory (CTIO), astronomers have mapped the outermost regions of a galactic globular cluster known as NGC 6809. Results of the study, published May 24 on the arXiv pre-print server, could improve our understanding of this cluster and its surroundings.

There are many hard lessons learned from the pandemic. One is that our food system needs a serious reboot. Luckily, we need only look to nature's cycles for clues on how to fix it.

University of Queensland scientists working to unlock the mysteries Australia's deadly stonefish have made a discovery which could change how sting victims are treated in the future.

South East Queensland's eucalypt trees can provide everything from medicines to tools, traps and building materials, according to rediscovered records of regional Indigenous knowledge.

A deep analysis of supply chains by researchers in the Lundquist College of Business finds that a firm's role in the chain can have a large influence on borrowing and lending strategies.

Climate change will make Australia hotter and drier in future, and we're starting to see the dangerous consequences of this in our rivers, lakes and streams.

The International Space Station (ISS) is not only the largest and most sophisticated orbiting research facility ever built, it is arguably the most important research facility we have. With its cutting-edge facilities and microgravity environment, the ISS is able to conduct lucrative experiments that are leading to advances in astrobiology, astronomy, medicine, biology, space weather and meteorology, and materials science.

Many plants can easily be regenerated and multiplied using cuttings. Crucial is that the cutting can initiate the formation of roots, a process called adventitious rooting. Sanaria Abbas Jaafer Alallaq showed in her Ph.D. thesis that some of the molecular regulators that control the initiation of adventitious roots in plants are similar in non-woody and woody plants like Norway spruce and poplar. She will defend her Ph.D. thesis at Umeå University on Thursday 3 June.

Up to three quarters of the biodiversity living on Western Australia's iconic ironstone mountains in the State's Mid West (known as Banded Iron Formations) could be difficult or impossible to return quickly to its previous state after the landscape has been mined, a Curtin University study has found.
