New tools for pandemic prevention research: DNA sequencing from water and leech
In a new scientific investigation headed by the German Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), water from African and Mongolian waterholes as well as bloodmeals from Southeast Asian leeches were assessed for the ability to retrieve mammalian viruses without the need to find and catch the mammals. The scientists analysed the samples using high throughput sequencing to identify known viruses as well as viruses new to science.

Sunflower peptide as 'template' for potential analgesic
A naturally occurring peptide in sunflower seeds was synthetically optimised and has now been identified as a potential drug for treating abdominal pain or inflammation (in the gastrointestinal tract, abdominal area and/or internal organs).

Honey, we shrunk the intense XUV laser
An international team of researchers has demonstrated a new concept for the generation of intense extreme-ultraviolet (XUV) radiation by high-harmonic generation (HHG). Its advantage lies in the fact that its footprint is much smaller than currently existing intense XUV lasers. The new scheme is straightforward and could be implemented in many laboratories worldwide, which may boost the research field of ultrafast XUV science. The detailed experimental and theoretical results have been published in Optica.

Human 'time neurons' encode specific moments in time
Neurons in the hippocampus fire during specific moments in time, according to research recently published in JNeurosci. The cells may contribute to memory by encoding information about the time and order of events.

Transforming the layered ferromagnet F5GT for future spintronics
An Australian-Chinese collaboration achieves record-high electron doping in a layered ferromagnet, causing magnetic phase transition--with significant promise for future electronics. Control of magnetism by electric voltage is vital for developing future, low-energy high-speed nano-electronic and spintronic devices, such as spin-orbit torque devices and spin field-effect transistors.

A way to surmount supercooling
Osaka University researchers study the use of nanoparticles to induce crystallization of supercooled aqueous solutions to clathrate hydrates. On the basis of scanning electron microscopy images, they discovered that silver nanoparticles are much more effective compared with palladium or gold. This research may open the way for new latent heat energy storage materials via enhanced supercooling control.

Boring to study slow earthquakes
Slow earthquakes are long-period earthquakes that are not so dangerous alone, but are able to trigger more destructive earthquakes. Their origins lie in tectonic plate boundaries where one plate subsides below another. Though the causal mechanism is already known, there has been a lack of data to accurately model the life cycle of slow earthquakes. For the first time, researchers use deep-sea boreholes to gauge pressures far below the seafloor.

Underground fiber optic sensors record sounds of COVID lockdown, reopening
In March 2020, daily life in the United States changed in an instant as the country locked down to deal with the initial wave of the COVID-19 pandemic. New research reveals how residents in one community returned to their routines as the restrictions lifted, according to a team of Penn State scientists.

Virtual reality boosts brain rhythms crucial for neuroplasticity, learning and memory
A new discovery in rats shows that the brain responds differently in immersive virtual reality environments versus the real world. The finding could pave the way for "virtual reality therapy" for learning and memory-related disorders ranging including ADHD, autism, Alzheimer's disease, epilepsy and depression.

Paleonursery offers rare, detailed glimpse at life 518 million years ago
All life on Earth 500 million years ago lived in the oceans, but scientists know little about how these animals and algae developed. A newly discovered fossil deposit near Kunming, China, may hold the keys to understanding how these organisms laid the foundations for life on land and at sea today, according to an international team of researchers.

A new type of supernova illuminates an old mystery
A worldwide team led by scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. The discovery also sheds new light on the thousand-year mystery of the supernova from A.D. 1054 that was seen all over the world in the daytime, before eventually becoming the Crab Nebula.

The discovery of a new type of supernova illuminates a medieval mystery
A worldwide team led by UC Santa Barbara scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive. They are thought to arise from the explosions of massive super-asymptotic giant branch (SAGB) stars, for which there has also been scant evidence.
