Despite Trump’s attempt to break US democracy in order to alter reality to his liking, Joe Biden will be sworn in as the next president. This has obvious implications for US’s plans for tackling climate change. The first is that we will now have an executive branch that recognizes science, that climate change is real, and will actually try to do something about it. Immediately this means rejoinin

Elevassistenter är numera en större yrkesgrupp än fritidspedagogerna i den svenska skolan. På många håll brottas de med tuffa pedagogiska utmaningar som resurser till elever i behov av särskilt stöd, men de har låg eller ingen pedagogisk utbildning alls. Forskning saknas om hur deras insats påverkar elevernas resultat, enligt en ny översiktsstudie vid Linköpings universitet.

Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern coast of the island. Updating ice sheet models with this open valley could provide additional insight for future climate change predictions.

A team of young scientists from the Institute of Natural Sciences and Mathematics of South Ural State University, under the guidance of physicist and mathematician Professor Sergei Podoshvedov, have proposed an algorithmic generator of the nonclassical state of light representing a "Schrödinger's cat state" of a very large amplitude. This algorithm plays an important role in quantum coupling and q

Industry has an increasingly urgent need to switch to sustainable, synthetic schemes to access widely used chemicals. In this context, it is crucial to come up with heterogeneous photocatalysis processes using readily available, metal-free catalysts.

Chemotherapy is defined as the use of chemicals to reach and damage cancer cells. On its way toward the tumor, the drugs can affect healthy cells, as well. For example, cisplatin, a common drug used in clinical treatments, is not selective and causes unwanted secondary effects such as vomiting, fever and loss of sensitivity, among others. These effects often halt the treatment. It is of great impo

Medical student Semir Bulle knows what it's like to live in fear of the police. A child of Ethiopian refugees, he was carded a dozen times in one year while growing up in northwestern Ontario. Bulle says those interactions sent a message: "The police are going to be watching me, and I have to be sure I'm looking nonsuspicious, so they don't try to harass me today."

An inexpensive monitoring system with 3-D-printed parts and low-cost sensors might not last as long as a commercial one, but it can be just as accurate, researchers found.

Almost all truly intriguing systems are ones that are far away from equilibrium—such as stars, planetary atmospheres, and even digital circuits. But, until now, systems far from thermal equilibrium couldn't be analyzed with conventional thermodynamics and statistical physics.

En konflikt mellem de norske kommuner og praktiserende læger endte i oktober i strejke. Kort efter greb regeringen ind. Hvad fik lægerne til at strejke midt i en pandemi? Urimeligt lange arbejdsuger og manglende muligheder for at sige fra, lyder forklaringen fra Nils Kristian Klev, formand for Allmennlegeforeningen.

Dansk Selskab for Almen Medicin har indstillet sin formand, Anders Beich, til en bestyrelsespost i Lægevidenskabelige Selskaber. Bestyrelsens sammensætning besluttes på et repræsentantskabsmøde torsdag 12. november.

The transition to remote learning coupled with an unequal distribution of second-shift responsibilities has placed teachers who are also mothers under immense stress, according to a small new study. Researchers explored the experiences and challenges facing teacher-mothers who perform the roles of educator in the classroom and parent at home, while also typically carrying out more household labor

You’ve probably seen numerous photos and renderings of Europa, its icy surface covered in reddish streaks. However, those images are all captured with illumination from the sun. A new analysis from NASA’s Jet Propulsion Laboratory (JPL) suggests that there might be something interesting on the Jovian moon’s dark side. The intense radiation bombarding Europa might make it glow in the dark , and th

Word-of-mouth has always been a powerful mantra for marketing, whereby a positive consumer passes on their recommendation of product or service to their friends, family, and work colleagues. In the age of social networking, electronic word-of-mouth (eWoM) becomes a potentially even more powerful tool. Social media can amplify the positive message especially of those one might refer to as "influenc

Recently, Prof. Zheng Xiaohong's research group from the Institute of Solid State Physics (ISSP) of the Hefei Institute of Physical Science (HFIPS) predicted a new two-dimensional (2-D) tin dioxide (SnO2) monolayer phase (P-4 m2) via first-principles calculations.

Recently, a research group led by Prof. Wang Zhenyang from the Institute of Solid State Physics of the Hefei Institutes of Physical Science (HFIPS) reported a novel method to prepare high-performance supercapacitors with ultra-high energy storage density.

It is thought that over 1,000 kilograms of so-called interplanetary dust falls to Earth every day. This dust is produced by an untold number of small faint meteors, discarded remnants of asteroids and comets that pass by the Earth. Two ways to study faint meteors are radar and optical observations, each with advantages and limitations. Astronomers have combined specific observations with both meth

Researchers can now more accurately and precisely target specific proteins in yeast, mammalian cells and mice to study how knocking down specific protein traits can influence physical manifestation in a cell or organism.

Nanographene is a material that could radically improve solar cells, fuel cells, LEDs and more. Typically, the synthesis of this material has been imprecise and difficult to control. For the first time, researchers have discovered a simple way to gain precise control over the fabrication of nanographene. In doing so, they have shed light on the previously unclear chemical processes involved in nan

Vahram Muradyan T he first day of my first year of teaching began with a bundle of nerves and a half-eaten honey bun. At 5:30 a.m., I drove from the cheap apartment I shared with five roommates to the high school in Prince George’s County, Maryland, where, 22 years old and just a year out of college, I’d been hired to teach English. My trunk was full of colorful posters, flip charts, and laminate

A blue-suited Joe Biden knelt. As a parent who had tragically lost a child, he wanted to get close to a child who had tragically lost a parent. Biden put his arm on her black chair. Six-year-old Gianna Floyd turned her head to the right. She locked eyes with the presidential candidate. Gianna saw the empathetic body before her, but perhaps she also saw the millions of empathetic bodies protesting
