Gloves, masks, and signs—protest essentials. (Clay Banks / Unsplash/) Protesting has always been risky business. The current situation in the US, with people in all 50 states standing up to racism and police brutality, is no exception. But since we’re still in the middle of a pandemic, these demonstrations have an extra layer of risk. If you want to support the cause from home, you can help by do
Scientists in Netherlands explore possible link between deficiency and Covid-19 deaths Coronavirus – latest updates See all our coronavirus coverage Patients who have died or been admitted to intensive care with Covid-19 have been found to be deficient in a vitamin found in spinach, eggs, and hard and blue cheeses, raising hopes that dietary change might be one part of the answer to combating the
Throughout the coronavirus pandemic, we’ve been eagerly awaiting a return to normal. We want to be able to go out again, see our friends, and be in public places without feeling like we’re risking our health or that of others. Now that Covid-19 case counts have gone down and restrictions are starting to lift, it seems we’re at last on the path back to some semblance of normalcy. But as recent eve

Telephone interventions could be used to successfully treat symptoms of cancer such as fatigue, depression and anxiety, new research in the Cochrane Library reports. This could help patients receive the care they need during the current Covid-19 pandemic when face- to- face access with medical professionals is limited.
Researchers from the University of Tsukuba identified the protein MafB as a key molecular actor in the development of FSGS. They showed that MafB-lacking mice develop FSGS and that treatment of FSGS mice with atRA, an agent known to induce the production of MafB, partially reversed the development of the disease. These findings provide new insights into a potential novel therapeutic target for FSG
A paper recently published in Nature Communications is the first to show a connection between demand from certain developed countries for agricultural commodities and the growing risk of malaria in the countries that supply those goods.

In a new study, published June 5, 2020, in the Journal of Experimental Medicine, scientists at La Jolla Institute for Immunology (LJI) shows that antibodies against JEV are 'cross-reactive' and can also recognize Zika virus. Unfortunately, these antibodies can actually make Zika cases more severe. The research, conducted in mice, is the first to show that T cells can counteract this dangerous phen
Research from the University of Sheffield has found that the chance of finding Earth-like planets in their early stages of formation is much higher than previously thought.
Are scientists who win Nobel Prizes different in key ways from their peer researchers? What happens to the quality of a scientist's work after they win a Nobel Prize?
They're microscopic miners. Some species of aquatic bacteria draw in dissolved iron from their watery environment and store it in specialized compartments called magnetosomes. They use its magnetic properties to navigate, sort of like ancient mariners using a lodestone to keep their bearings.
Leaderless, decentralized protest is both a strength and a weakness, historian and civil rights scholar Clayborne Carson argues. As spontaneous and loosely organized demonstrations against the death of George Floyd continue to erupt across the world, Carson has a message to activists: There needs to be some kind of leadership stating objectives of the current movement . As a student at UCLA in 19
Around the start of the COVID-19 crisis, U.S. and European government officials decided to relax their usual vigilance of possible collusion among business interests. The authorities took this uncommon action of easing antitrust guidelines to in order to promote intercorporate cooperation to manufacture sorely needed supplies in the fight against the pandemic, especially medical equipment.

For the first time, researchers of Tomsk Polytechnic University jointly with teams from Taiwan and Spain have experimentally confirmed the flat focusing mirror effect, which they previously predicted. Physical properties of the effect and simplicity of its reproduction make it promising for application in microelectronics, photonics, and on-chip systems, where a single microcircuit functions as an
When we think of wrinkles, we usually envision the lines etched into our skin, for some an unwelcome reality and for others a proud sign of a life well-lived. In material science, wrinkles can also be either wanted or unwanted. But the physical factors that cause wrinkling to occur are not yet fully understood.
Stay hydrated and prepared for anything, even in the most peaceful of protests.

From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.

The images in the media have been strong and often disturbing in the wake of George Floyd's death at the hands of Minneapolis police. We process them through our biases, both conscious and unconscious. That's the domain of Travis Dixon, who studies media stereotypes and their impact as a professor of communication at the University of Illinois at Urbana-Champaign. He spoke with News Bureau social
As we near the 100-day mark since the pandemic was declared, one area getting a significant attention is the workplace, where a window is opening for good ideas to move from the fringes to the mainstream.
New instruments can generate maps of neutron stars in unprecedented detail, but physicists are still trying to figure out what lies beneath the surface. (NASA, NICER, GSFC's CI Lab/) The Earth is a balmy oasis in cosmos of raging extremes, and few bodies are more extreme than neutron stars. These objects form when stars of a certain mass die, and their cores collapse and cram a couple of suns wor
A new stretchy material called HELIOS could pave the way for flexible digital screens that heal cracks or light-emitting robots that locate survivors in dark, dangerous environments, researchers report.

Amazing things happen in the day-to-day sky that often go unnoticed during our normal routine. Just such a curious 'non-event' happened this week, when Venus reached inferior conjunction between the Earth and the sun on its race from the dusk to the dawn sky. And what's even more amazing is the fact that some skilled observers followed this passage and caught sight of Venus as a tiny blazing 'ring
Could household slime become a tool to help solve crimes? That's the question U of T Mississauga forensic science graduate Leanne Byrne (H. BSc, 2020) sought to answer in a recent study that tested a popular children's "slime" recipe as a technique to enhance the appearance of hard-to-see fingerprints in forensic investigations.
Cosmic rays may have left indelible imprint on early life, researchers report. They propose that the influence of cosmic rays on early life may explain nature’s preference for a uniform “handedness” among biology’s critical molecules. “We are irradiated all the time by cosmic rays.” Before there were animals, bacteria, or even DNA on Earth, self-replicating molecules were slowly evolving their wa
Cardiovascular disease, which kills one Australian every 12 minutes, is caused by a hardening of the arteries due to abnormal deposits of fat and cholesterol (known as plaque) in the inner lining of the artery; a process known as atherosclerosis. When plaque deposits rupture, this can cause heart attacks and stroke. But what if the plaque could be prevented from rupturing using microscopic nanopar
A well-known mantra, "the customer is always right," was once regarded by retailers as good customer relations, but now many fear it has led to a culture in which consumers can freely subject shopworkers to verbal and physical abuse with impunity.
As the coronavirus pandemic brings with it a number of enormous challenges, almost every team in every workplace is facing adversity, and some teams will recover more successfully than others. New research from the University of Delaware's Sal Mistry suggests that there are a few key steps that leaders can take to help their teams swim instead of sink through difficult times like these.
Nd-doped phosphate glasses are used in high energy / high power laser applications due to their low nonlinear refractive index and high stimulated emission cross section. In order to ensure superior properties of laser glasses, the composition of practical laser glasses is complex. However, the traditional experimental method of composition fine-tuning to improve properties of glass is slow and la
Tomorrow is the first World Green Roof Day. Cities around the world will celebrate the well-documented environmental, economic and social benefits of green roofs. New ground-level green spaces are difficult to create in high-density urban areas. As a result, other forms of city greening—green roofs, green walls and vegetated facades—are increasingly popular.
To make climate scenarios work for decision-makers, an international team of researchers developed a comprehensive interactive online platform. It is the first of its kind to provide the tools to use those scenarios—from climate impacts to mitigation and energy options—to a broader public beyond science. The scenarios help policy makers and businesses, finance actors and civil society alike to ass
The capacity of a stem cell population to generate several distinct cell types in a temporally defined manner is fundamental to both organ development and homeostasis. To achieve this, stem cells must carefully balance self-renewal and commitment to cellular differentiation, but how this is regulated at the genetic level has remained unclear.
The capacity of a state and the degree of economic inequality among its residents will determine how successful it is in coping effectively with a pandemic like COVID-19. Whether it is a democracy or a dictatorship matters relatively less, according to recent research by Wharton management professor Mauro Guillén.

Det handlar inte bara om styrdokument, utan också om vad individernas egna uppfattningar. Det konstaterar Kristina Belančić vid Umeå universitet efter att ha undersökt vad som påverkar hur samiska språket används i sameskolan. Hennes forskning visar att elever vill använda samiska men tycker sig ha begränsade möjligheter och svårt att utveckla både skrift- och talspråk. – Å ena sidan riskerar sam
What are the police for? Why are we paying for this? The death of George Floyd and the egregious, unprovoked acts of police violence at the peaceful protests following his death have raised these urgent questions. Police forces across America need root-to-stem changes—to their internal cultures, training and hiring practices, insurance, and governing regulations. Now a longtime demand from social
With dozens of digital contact tracing apps already rolled out worldwide, and many more on the way, how many people need to use them for the system to work? One number has come up over and over again: 60%. That’s the percentage of the population that many public health authorities documented by MIT Technology Review’s Covid Tracing Tracker say they are targeting as they attempt to protect their c
The Atlantic HONG KONG—For most of last year, life here was intertwined with protests. Those not attending demonstrations might have found themselves caught in the middle of a police clearance operation, with officers chasing black-clad protesters into subway stations or around shopping malls.
