At least 12,000 Americans have already died from COVID-19 this month, as the country inches through its latest surge in cases. But another worrying statistic is often cited to depict the dangers of this moment: The number of patients hospitalized with COVID-19 in the United States right now is as high as it has been since the beginning of February. It's even worse in certain places: Some states,
There's a stubborn, heat-absorbing particle that floats along in Earth's atmosphere: It initially doesn't like water, it absorbs light, and it takes its time moving on. Black carbon in the atmosphere tends to linger until it finally absorbs enough water to fall from the sky. In the meantime, black carbon absorbs the sun's energy and heats up surrounding air, creating a radiative effect.
Exciting new research has revealed that a drop in atmospheric carbon dioxide caused a dramatic cooling 133 million years ago, when dinosaurs roamed the world. Better understanding of the effects of past fluctuations in atmospheric CO2 are critical to understand how heat moves around the globe, which also controls how much ice can build up in polar regions.

Most of the cells in our bodies—be they bone, muscle or pancreas cells—are locked into the right place with the help of tiny anchors (called 'focal adhesions'). These strong anchors use protein chains to link the cell to collagen, the protein that gives structure to our body.
When listening to music, we don't just hear the notes produced by the instruments, we are also immersed in its echoes from our surroundings. Sound waves bounce back off the walls and objects around us, forming a characteristic sound effect—a specific acoustic field. This explains why the same piece of music sounds different when played in an old church or a modern concrete building.

Calves taught to use toilet area with rewards and mild punishments, limiting ammonia release A herd of cows has been "potty-trained" in an experiment that scientists say could pave the way for more environmentally friendly farms. Waste from cattle farms often contaminates soil and waterways and contributes to greenhouse gas emissions and the acidification of soil. For this reason, toilet-training
The notion of dimension at first seems intuitive. Glancing out the window we might see a crow sitting atop a cramped flagpole experiencing zero dimensions, a robin on a telephone wire constrained to one, a pigeon on the ground free to move in two and an eagle in the air enjoying three. But as we'll see, finding an explicit definition for the concept of dimension and pushing its boundaries has…

Most of the research concerned with hazards like flooding, landslides, or wildfires describes only one hazard at a time, but the Intergovernmental Panel on Climate Change's latest assessment report states that anthropogenic climate change is increasing the likelihood of compound hazards—events where more than one hazard interact with multiplicatively destructive consequences. A recent study has fo
Environmental targets to limit excess nitrogen require the large-scale deployment of dedicated nitrogen mitigation strategies to avoid a strong increase in the risk of food insecurity. Without these measures, the amount of dietary energy available to people would be greatly reduced, which would in turn lead to high food prices and an increase in the number of undernourished people.
Researchers observe in a series of photos an unexpected rescue of two young wild boars from a trap. The whole rescue took less than half an hour thanks to a clever adult female wild boar. Aside from the fact of the rescue, there are signs that the rescuer was exhibiting and acting out of empathy for the captives. There is a danger in attributing human-like motivations to animal behavior. We have

In times of exacerbating biodiversity loss, reliable data on species occurrence are essential, in order for prompt and adequate conservation actions to be initiated. This is especially true for freshwater ecosystems, which are particularly vulnerable and threatened by anthropogenic impacts. Their ecological status has already been highlighted as a top priority by multiple national and internationa
The languages of the world are all unique, but also share important similarities. These mostly lie in the grammatical elements each of the approximately 7000 human languages contain, the word parts and rules that speakers can use to build a sentence. Traditionally, linguists either assume that the explanation for these similarities is that all people are born with a blueprint for these grammatical
A polynya is a region of open water that is surrounded by sea ice. These areas fluctuate throughout seasons, and weather events can influence their size and development. Extremely high wind in February 2018 led to a polynya that developed in the Wandel Sea off the coast of Greenland.

Usually, the individuals of a population of marine species that have the potential to disperse over long distances all share a similar genetic composition. Yet every now and then, at small, localized sites, small groups of genetically different individuals suddenly appear within populations for a short period of time. A new study explains how this chaotic formation of genetic islands can occur in
The world's largest car manufacturer by volume has been sluggish in its efforts to electrify compared to competitors. But Toyota has just announced a huge investment in battery technology that may be a sign it's shifting course. Although Toyota's Prius hybrid was the first electrified vehicle to really hit the mainstream, the company failed to capitalize on its early lead. It still doesn't sell a
Researchers have discovered a hormone in fruit flies that can help us better understand how human metabolism is regulated. The findings could pave the way for treating diseases such as obesity and diabetes. Hormones are chemical messengers that signal to organs what to do while getting them to work together. Hormonal imbalances can lead to countless diseases and are partly responsible for the fac
"Since its invention, television has shaped this country's self-image. To the extent that we share notions of 'normal,' 'acceptable,' 'funny,' 'wrong,' and even 'American,' television has helped define them. For decades, Black writers were shut out of the rooms in which those notions were scripted, and even today, they must navigate a set of implicit rules established by white executives––all whi
Textbook wording that portrays climate change information as uncertain can influence how middle and high school students feel about the information, a study suggests. The study has implications for how teachers can prepare students to face misinformation about climate change . "I thought students' knowledge or social norms surrounding climate change would buffer them from misinformation," says st
Många fler än tidigare vill få svåra hälsobesked först via journaler på nätet, visar en studie. Men många inom vården är skeptiska till att patienter får ta del av till exempel en cancerdiagnos, innan en läkare hunnit ta kontakt. Enligt studien får cirka två procent av patienterna svåra besked först via Journalen på webbtjänsten 1177.se. Studien visar att mångdubbelt, 17,7 procent, vill ta emot s
During the COVID-19 pandemic, we have seen an explosion of new words and phrases in English (for example, COVIDiot) and other languages Coronaspeck in German to describe lockdown weight gain) that have helped us make sense of a period defined by social confusion and constant change, as well as global stagnation.
Researchers from Skoltech and their colleagues from China have experimentally shown superconductivity in cerium superhydrides CeH9 and CeH10, pointing the way to lower-pressure and potentially room-temperature superconductors. The paper was published in the journal Physical Review Letters.
When solar wind slams into Earth's magnetic field, the impacts ripple down through the planet's ionosphere, the outer shell of the atmosphere full of charged particles. A global array of high-frequency radars known as the Super Dual Auroral Radar Network (SuperDARN) tracks ionospheric plasma circulation from the ground, giving researchers insights into the interactions between solar wind, the magn
The COVID-19 pandemic has sharpened our focus on food—whether it be due to concerns relating to supply chain integrity, the viability of rural communities, or a rediscovery of home-cooking during lock-down.

Wouldn't it be nice if there was a single multi-vitamin that could adapt uniquely to your body's specific needs to help you achieve mind-body balance? And wouldn't it be even better if it tasted like juicy, ripened, wild raspberries? There may not be a multi-vitamin that can do it all, but there sure is a multi-mushroom gummy that can. Meet WonderDay Mushroom Gummies , the first mushroom multi gu
"Dumpster diving" is a term used to describe studies using data from the Vaccine Adverse Events Reporting System database by authors, almost always antivaxxers, who don't understand its limitations. Last week, non-antivax doctors who should know better fell into this trap when they promoted their study suggesting that COVID-19 mRNA vaccines are more dangerous to children than the disease. The pos
Ammonia is the second most produce industrial chemical in the world. It is used for a variety of things , but mostly fertilizer: About 80% of the ammonia produced by industry is used in agriculture as fertilizer. Ammonia is also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes and other chemicals. In 2010 the
On Sept. 15, 2021, the next batch of space tourists are set to lift off aboard a SpaceX rocket. Organized and funded by entrepreneur Jared Isaacman, the Inspiration4 mission touts itself as "the first all-civilian mission to orbit" and represents a new type of space tourism.
The combination of electrochemistry and flow technology holds much promise for the sustainable production of valuable chemicals, such as biobased feedstocks. Researcher Yiran Cao has explored electrochemical organic synthesis in flow, and especially continuous-flow microreactors, a new and exciting field that presents several challenges.

In the wake of the COVID-19 pandemic, we must not squander the clean energy gains that were made through reduced human activity and economic downturn during the periods of lockdown and beyond. That is the message from recent research published in the International Journal of Global Warming.
Epigenetics is the study of changes in gene activity which are not caused by changes in DNA sequences. DNA methylation—the addition of methyl groups to DNA—is the most well-known epigenetic modification. Lead exposure is known to cause epigenetic changes, and understanding these changes will help to more completely understand the impact and consequences of lead toxicity. This is especially importa
Research findings published today by scientists at National Jewish Health and the Union of Concerned Scientists (UCS) in the Journal of Exposure Science and Environmental Epidemiology, show that climate change has increased ground-level ozone, a respiratory irritant that affects residents in Colorado.
