HSE University researchers Yuri Markov and Natalia Tyurina discovered that when people visually estimate the size of objects, they are also able to consider their distance from the observer, even if there are many such objects. The observers rely not only on the objects' retinal representation, but also on the surrounding context.

A combination of robust vaccination programmes and strict physical distancing rules could avoid recurring peaks of COVID-19 without the need to rely on stay-at-home restrictions, according to a new study by epidemiologists and demographers from WorldPop at the University of Southampton, in collaboration with The Chinese University of Hong Kong.

Scientists have discovered the first evidence of protein folding driven by liquid-liquid phase separation, a phenomenon in which fluids form into microscopic droplets and separate inside cells -- like drops of oil in water.

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the realization of quantum computers, among other things. They are published in the prestigious journal Physical Review X, and covered by the Physics Magazine of the American Physical Society.

Exploratory analyses including 17,178 participants find that higher vaccine efficacy is obtained with a longer interval between the first and second standard dose (81% for 3-month interval vs 55% for up to 6-week interval). In addition, a single dose of vaccine is highly efficacious in the first 3 months (76% efficacy from 22 days after vaccination onwards).

The results, recently published in the journal Communications Biology, have important applications in the field of coevolutionary biology

The physical movement of species determines their potential scope to leave their primary ecosystem behind in the quest for new niches in which to survive or reproduce--a decisive factor for the processes that determine their genomic characteristics.

A chemist from RUDN University, working with a group of colleagues, synthesized three new chalcogenides (compounds that contain metals and elements from group 16 of the periodic table). The team suggested an unusual approach to synthesis that was based on iodine. An article about the work was published in the Dalton Transactions journal.

Biotechnologists from RUDN University in collaboration with Lomonosov MSU and Kurchatov institute made an important contribution to the technology of phosphate and nitrate biocapture from wastewater using Lobosphaera algae fixed on the filters.The biomass obtained in the course of this process can be used as a fertilizer. The results of the study were published in the Journal of Water Process Engineering.

DURHAM, N.C. -- Duke researchers have been studying something that happens too slowly for our eyes to see. A team in biologist Philip Benfey's lab wanted to see how plant roots burrow into the soil. So they set up a camera on rice seeds sprouting in clear gel, taking a new picture every 15 minutes for several days after germination.

We are most familiar with the four conventional phases of matter: solid, liquid, gas, and plasma. Changes between two phases, known as phase transitions, are marked by abrupt changes in material properties such as density. In recent decades a wide body of physics research has been devoted to discovering new unconventional phases of matter, which typically emerge at ultra-low temperatures or in specially-structured materials.

Boys who regularly play video games at age 11 are less likely to develop depressive symptoms three years later, finds a new study led by a UCL researcher.

The study, published in Psychological Medicine, also found that girls who spend more time on social media appear to develop more depressive symptoms.

Taken together, the findings demonstrate how different types of screen time can positively or negatively influence young people's mental health, and may also impact boys and girls differently.

When women undergo surgical treatment for breast cancer, they often also have reconstructive surgery but new QUT research reveals many women feel left out of the decision making.

Most Chinese working in the cities return to work today after a 7-day public holiday of Spring Festival. The annual Spring Festival, which also marks the start of Chinese New Year, traditionally begins with the second new moon following the winter solstice, usually in January or February. Like westerners on Thanksgiving and Christmas, people across China return to their hometown to reunite with family and friends. However, the sudden outbreak of COVID-19 last year halted the largest holiday mobilization in the world.

Covid-19 has not made people any less concerned about climate change - despite the pandemic disrupting and dominating many aspects of their lives, a study suggests.

Over a period of 14 months - including the first three months of the Covid-19 lockdown - neither concern about climate change nor belief in the severity of the problem declined in the UK, the research found.

Researchers compared responses to the pandemic with the financial crisis of 2008 to better understand how worries and priorities can change in a crisis.

An international study in which the University of Granada participated--recently published in the journal Scientific Reports--has identified a new fossil record of these mysterious animals in the northeast of Taiwan (China), in marine sediments from the Miocene Age (between 23 and 5.3 million years ago)

These organisms, similar to today's Bobbit worm (Eunice aphroditois), were approximately 2 m long and 3 cm in diameter and lived in burrows
