Researchers have found white-tailed deer ­-- the most abundant large mammal in North America -- are harboring SARS-CoV-2 variants that were once widely circulated, but no longer found in humans.

A team of researchers has developed a computational pipeline to identify and better understand viroids and viroid-like covalently closed circular RNAs (cccRNAs, also referred to as, simply, circular RNAs).

A new study finds that raised temperatures cause a pathogenic fungus known as Cryptococcus deneoformans to turn its adaptive responses into overdrive. Heat increases its number of genetic changes, some of which might presumably lead to higher heat resistance, and others perhaps toward greater disease-causing potential.

The stubborn superbug Clostridium difficile, or C. diff, may have met its match. A esearcher is reporting the first well-controlled study to demonstrate the effectiveness of a new medicine for patients with the debilitating recurrent infection and disease.

Researchers have developed a sustainable, inexpensive two-step process that can upcycle organic carbon waste -- including lignin, a difficult-to-breakdown material that gives plants their structure. By processing waste through a microbe-driven biorefinery, the researchers turned lignin into carbon sources that could be used in high-value, plant-derived pharmaceuticals and antioxidant nutraceuticals as well as carbon-based nanoparticles for drug or chemical delivery.

In situ observation and recording of important liquid-phase electrochemical reactions in energy devices is crucial for the advancement of energy science. A research team has recently developed a novel, tiny device to hold liquid specimens for transmission electron microscopy (TEM) observation, opening the door to directly visualizing and recording complex electrochemical reactions at nanoscale in real-time at high resolution. The research team believes that this innovative method will shed light on strategies for fabricating a powerful research tool for uncovering the mysteries of electrochemical processes in the future.

A research team has developed a novel chemical tool to reveal how bacteria adapt to the host environment and control host cells. This tool can be used to investigate bacterial interactions with the host in real-time during an infection, which cannot be easily achieved by other methods.

Photosynthesis in plants and some bacteria relies on light-harvesting (LH) supramolecules, which come in different structures. So far, these LH molecules have not been artificially prepared. In a recent study, scientists managed to synthesize LH nanorings via self-assembly of chlorophyll derivatives and examined the external conditions that drove their formation. Their findings could help us study artificial photosynthesis and possibly pave the way for novel materials for LH devices like solar cells.

A new article shows that an experimental vaccine against Marburg virus (MARV) was safe and induced an immune response in a small, first-in-human clinical trial. The vaccine could someday be an important tool to respond to Marburg virus outbreaks.

By repurposing one of the human body's natural cargo transports, a research team has developed a vaccine platform that could curb certain engineering challenges, storage demands and side effects of vaccines that combat HIV epidemics and the COVID-19 pandemic.

Physicists have found a new way to switch superconductivity on and off in magic-angle graphene. The discovery could lead to ultrafast, energy-efficient superconducting transistors for 'neuromorphic' electronics that operate similarly to the rapid on/off firing of neurons in the human brain.

Researchers already knew the atoms in perovskites react favorably to light. Now they've seen precisely how the atoms move when the 2D materials are excited with light. Their study details the first direct measurement of structural dynamics under light-induced excitation in 2D perovskites.

Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in graphene. Now, researchers have discovered quasiparticles in a classical system at room temperature: a two-dimensional crystal of particles driven by viscous flow in a microfluidic channel. Coupled by hydrodynamic forces, the particles form stable pairs -- a first example of classical quasiparticles, revealing deep links between quantum and classical dissipative systems.

A transporter which some bacteria use to recycle fragments of their cell wall has been discovered. Researchers found that the transporter controls resistance to certain kinds of cell-wall targeting antibiotics.

The structure of two-dimensional titanium oxide brakes-up at high temperatures by adding barium; instead of regular hexagons, rings of four, seven and ten atoms are created that order aperiodically. A team has now solved the riddle of two-dimensional quasicrystal formation from metal oxides.

The World Health Organization (WHO) ranks antibiotic resistance as one of the top ten threats to global health. There is therefore a great need for new solutions to tackle resistant bacteria and reduce the use of antibiotics. A group of researchers are now presenting a new spray that can kill even antibiotic-resistant bacteria, and that can be used for wound care and directly on implants and other medical devices.
