When the pandemic sent many students home, University of Arizona researchers and Tucson teachers quickly adapted to the challenges of teaching science without a lab or classroom. A new paper, published in the journal The American Biology Teacher, outlines an at-home science lesson developed at UArizona to teach high schoolers about bioinformatics and SARS-CoV-2, the virus that causes COVID-19. The lesson plan is available for interested high school teachers across the country.

A new study examining the narratives and motivations of men and women in rural Alabama who used methamphetamine (meth) is forthcoming in Criminology, a publication of the American Society of Criminology. It is the first photo-ethnography to be published in the journal. The study was led by researchers Heith Copes (University of Alabama at Birmingham [UAB]), Fiona Brookman (University of South Wales), Jared Ragland (Utah State University), and Blake Beaton (Sam Houston State University).

Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling technique that is frequently used to cool atomic samples. The device used a recently developed technique the researchers call photon pressure coupling, which is predicted to be of use in detecting ultra-weak magnetic resonance (MRI) signals or for quantum-sensing applications that can help the search for dark matter.

The growing popularity of 3D printing for manufacturing all sorts of items, from customized medical devices to affordable homes, has created more demand for new 3D printing materials designed for very specific uses.

In the early solar system, a "protoplanetary disk" of dust and gas rotated around the sun and eventually coalesced into the planets we know today.

Procurement accounts for more than 10 percent of U.S. federal government spending. Yet the extent of competition for a procurement contract is not very robust, with contracts rarely having many bids and often having only one.

The Roman Empire was ruled by 175 men, from Augustus (63 BCE-19 CE) to Constantine XI (1405-53), including the Eastern or Byzantine Empire after the split in 395 CE, but excluding those who did not rule in their own right because they were minors during regencies or co-emperors.

Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have identified a protein that plays a key role in how the brain regulates appetite and metabolism. Loss of the protein, XRN1, from the forebrain, resulted in obese mice with an insatiable appetite, according to a new study published in the journal, iScience.

Every day, social media users are exposed to fake news and political polarization on social networks. What makes people vulnerable to believing false information they find online?

New research led by Baylor University biology doctoral candidate William J. Matthaeus and professor of biology Joseph White, Ph.D., considers how plant freeze-intolerance affected forest cover and hydrology during the Pennsylvanian period, roughly 340 million to 285 million years ago during the Paleozoic Era, proposing improvements to climate projections for the past and future with plant function data.

Social exclusion is currently a topic that's being broadly discussed in the public sphere. It generally refers to a multidimensional process that is shaped by changes in the economic structure over the past few decades and is pushing an increasing share of the population to the economic margins, be it through unemployment, poverty or uncertain living conditions. It is commonly assumed that this results in social isolation among those affected, leaving them feeling excluded from public life.

Joshua trees, the tall, twisty succulents that mark the Mojave Desert, are survivors.

A wetter-than-average forecast for late October could dampen wildfires burning in Northern California and help ease drought conditions, according to the National Weather Service.

With the upcoming launch of the post-2020 global biodiversity framework, identification of conservation targets is essential. However, current global conservation targets focus on biodiversity conservation, ignoring ecosystem services and vulnerabilities.

Valerio Piazza is creating new 3D architectures built from an inventive form of nanowire. His research aims to push the boundaries of miniaturization and pave the way to more powerful electronic devices. He has just won the 2020 Piaget Scientific Award, whose prize money will fund his work at EPFL for a year.

On September 27, the research team led by Prof. MA Zhonghua at the Zhejiang University College of Agriculture & Biotechnology published an article titled "Fusarium BP1 is a reader of H3K27 methylation" in the journal Nucleic Acids Research.

The Graham and Crump groups at the University of Cambridge and the Svergun Group at EMBL Hamburg have discovered a mechanism by which the herpes simplex virus takes control of the molecular machinery of human cells. Their work reveals how a dedicated viral protein hijacks key host proteins, forcing the host cell to produce and release copies of the virus.

The FBI has joined the investigation into the oil spill that dumped thousands of gallons of crude off the coast of Orange County to determine whether any criminal violations occurred, the agency announced Thursday.

From the internet, to fiber or satellite communications and medical diagnostics, our everyday life relies on optical technologies. These technologies use optical pulsed sources to transfer, retrieve or compute information. Gaining control over optical pulse shapes thus paves the way for further advances.

While vaccination queues have become commonplace across Australia, the sight of hundreds of koalas lining up for a life-saving jab over coming months is still expected to turn some heads.

Plants are under attack by a variety of insect species. They have defense mechanisms to deal with this, including chemicals or sturdier leaves. But it's now been found that when wild black mustard plants defend themselves against an initial enemy, they already anticipate the need to later fend off other, different enemies. In fact, they even prepare for the most likely sequence of attackers. This remarkable research has now been published in the renowned scientific journal Nature Plants.

A mega-comet—potentially the largest ever discovered—is heading from the Oort Cloud towards our direction. Estimated to be 100–200 kilometers across, the unusual celestial wanderer will make its closest approach to the Sun in 2031. However, the closest it will come to Earth is to the orbit of Saturn.

A study involving some 11,000 dogs carried out at the University of Helsinki demonstrated that the gender, age an d breed of the dog, as well as any behavioral problems and certain environmental factors, are connected to hyperactive and impulsive behavior and inattention (ADHD).

Analytical chemists at the Department of Energy's Oak Ridge National Laboratory have developed a rapid way to measure isotopic ratios of uranium and plutonium collected on environmental swipes, which could help International Atomic Energy Agency analysts detect the presence of undeclared nuclear activities or material.

A team of fusion researchers at the Department of Energy's Oak Ridge National Laboratory used datasets from measurements on the Joint European Torus, or JET, tokamak to model an improved method for quantifying the amount of plasma-radiated power during a disruption of normal operations.
