For the second time in two years, Gildardo Urrego is scooping up piles of dead bees after an invisible evil invaded his hives in northwest Colombia, wreaking havoc among his swarms.

The ability to read is foundational to education, but prolonged school closures and distance learning due to the pandemic have imposed unique challenges on the teaching of many fundamental skills. When in-person classes resume, many students will likely need a period of catch-up learning, especially those who lag behind in basic reading skills.

In 2020, Denmark set one of the most ambitious climate targets in the world but its government has yet to come up with a plan to achieve...

The ocean floor is vast and varied, making up more than 70% of the Earth's surface. Scientists have long used information from sediments at the bottom of the ocean—layers of rock and microbial muck—to reconstruct the conditions in oceans of the past.

A team of international researchers went back to the formation of the solar system 4.6 billion years ago to gain new insights into the cosmic origin of the heaviest elements on the period-ic table.

Both Democrats and Republicans overwhelmingly favor politicians who support generous COVID-19 relief spending, yet remain deeply polarized over the legitimacy of the 2020 presidential election results and former President Donald Trump's second impeachment. Meanwhile, political experts find that the former president's actions and those taken by congressional supporters in the aftermath of the...

When Patrick Rottinghaus began college, he had no idea what he wanted to do with his career. He started out as an "Open" major while he explored possibilities.

Save your silver! It's better used for jewelry than as a catalyst for drugs.

In recent years, engineers have found ways to modify the properties of some "two- dimensional" materials, which are just one or a few atoms thick, by stacking two layers together and rotating one slightly in relation to the other. This creates what are known as moiré patterns, where tiny shifts in the alignment of atoms between the two sheets create larger-scale patterns. It also changes the way...

Parasitic flatworms known as agents of food-borne zoonoses were confirmed to use several species of thiarid snails, commonly found in freshwater and brackish environments in southeast Asia, as their first intermediate host. These parasites can cause severe ocular infections in humans who consume raw or improperly cooked fish that have fed on infected snails. The study, conducted in South Thailand...

Transfer RNAs (tRNAs) deliver specific amino acids to ribosomes during translation of messenger RNA into proteins. The abundance of tRNAs can therefore have a profound impact on cell physiology, but measuring the amount of each tRNA in cells has been limited by technical challenges. Researchers have now overcome these limitations with mim-tRNAseq, a method that can be used to quantify tRNAs in any...

In a twist befitting the strange nature of quantum mechanics, physicists have discovered the Hall effect -- a characteristic change in the way electricity is conducted in the presence of a magnetic field -- in a nonmagnetic quantum material to which no magnetic field was applied.

We know vaccination is very effective in preventing serious illness, but whether it stops coronavirus transmission is another storyAs Australia joins the worldwide Covid-19 vaccine rollout, researchers keep emphasising that while we know the various vaccines in use are strong at preventing hospitalisation and severe disease, it’s less clear how well they stop the virus spreading to other people....

When Patrick Rottinghaus began college, he had no idea what he wanted to do with his career. He started out as an "Open" major while he explored possibilities. Today, he is helping young people eager to find their place in the world by identifying their strengths and connecting them with careers that match their skill-set, interests and personality. As the father of three children, including a...

For practical applications, two-dimensional materials such as graphene must at some point connect with the ordinary world of 3D materials. Researchers have come up with a way of imaging what goes on at these interfaces, down to the level of individual atoms, with the goal of better controlling these materials' electronic properties.

Scientists aim to numerically investigative the roles of cooperative effects and disorder in photon escape rates from a cold atomic gas to construct a model that considers the vectorial nature of light. Thus, the study accounts for properties of light, previously neglected.

A vast iceberg almost the size of Greater London has broken away from the Antarctic ice shelf near a British research station, the British Antarctic Survey said Friday.

Whilst a great deal of research has studied the rates of photons escaping from cold atomic gases, these studies have used a scalar description of light leaving some of its properties untested. In a new paper published in EPJ B Louis Bellando, a post-doctoral researcher at LOMA, University of Bordeaux, France, and his coauthors—Aharon Gero and Eric Akkermans, Technion-Israel Institute of...

Neutron scattering is a technique commonly used in physics and biology to understand the composition of complex multicomponent mixtures and is increasingly being used to study applied materials such as food. A new paper published in EPJ E by Gregory N Smith, Niels Bohr Institute, University of Copenhagen, Denmark, shows an example of neutron scattering in the area of food science. Smith uses...

NUS scientists have devised a new method for the synthesis of nanographene molecules with a high product yield for the development of next generation quantum devices.

Who hasn't looked at the sky on a mild summer night and thought about the vastness of the universe? The trained eye can see the Andromeda galaxy as a distant spot. Thanks to the latest telescopes, we know that it consists of over a trillion stars. In the "nanocosm," clusters of individual light sources, such as molecules, also appear as points.
