The heatwave would have been almost impossible without human-caused climate change, a study says.
The president hails the changes as "historic", but critics say they are designed to avoid scrutiny.
New research suggest the universe is about 13.8 billion years old, according to researchers using observations from the Atacama Cosmology Telescope (ACT) in Chile.
Human fingerprint on record temperatures ‘has rarely, if ever, been clearer’, says reportThe record-breaking heatwave in the Siberian Arctic was made at least 600 times more likely by human-caused climate change, according to a study. Between January and June, temperatures in the far north of Russia were more than 5C above average, causing permafrost to melt, buildings to collapse, and...
Older women who eat more than one to two servings a week of baked or broiled fish or shellfish may consume enough omega-3 fatty acids to counteract the effects of air pollution on the brain, according to a new study.
A new study has dissected how radiotherapy alters the behavior of immune cells known as macrophages found in glioblastoma (GBM) tumors and shown how these cells might be reprogrammed with an existing drug to suppress the invariable recurrence of the aggressive brain cancer.
Researchers have developed a new drug that prevents blood clots without causing an increased risk of bleeding, a common side effect of all antiplatelet medications currently available. A new study describes the drug and its delivery mechanisms and shows that the drug is also an effective treatment for heart attack in animal models.
A commercial fisherman knew he was staring at a fish out of place when a barracuda landed in his net on Vancouver Island, far from its typical habitat in southern...
A new, 10-year study by researchers at the University of California, Davis, examined 35 dog breeds and found vulnerability from neutering, and the age at which they are neutered, varies greatly depending on the breed.
Biomolecular engineers at Rice University have found a C-worthy technique that dramatically enhances the accuracy of gene editing.
New modeling shows how social distancing could have better been implemented. The key? Longer periods of distancing would have helped -- but only to a point. More needed to be done.
Proponents of campaign finance reform claim that putting limits on how much money can be raised and spent to support a political candidate leads to more competitive elections by helping level the political playing field between incumbents—the people holding the political office—and challengers. However, a new study by two social scientists at the University of Missouri finds state campaign...
To catch a thief, the saying goes, you have to think like a thief. The same is true for invasive predators: to foil their depredations on native wildlife, scientists have to understand how they think.
Plants have to interpret temperature fluctuations over timescales ranging from hours to months to align their growth and development with the seasons.
A new proof-of-concept study reports evidence that a new testing method has the potential to rapidly identify radiation sickness based on biomarkers measured through a single drop of blood. Scientists say the test could help save lives through early and real-time identification of the condition to enable timely clinical interventions.
Biomolecular engineers have developed new tools to increase the accuracy of CRISPR single-base editing to treat genetic diseases.
In American history, we learn that the arrival of Spanish explorers led by Hernando de Soto in the 1500s was a watershed moment resulting in the collapse of Indigenous tribes and traditions across the southeastern United States.
With widespread, sustained declines in fertility, the world population will likely peak in 2064 at around 9.7 billion, and then decline to about 8.8 billion by 2100 -- about 2 billion lower than some previous estimates, according to a new study.

In living organisms, DNA is the storage unit of all genetic information. It is with this information that proteins are encoded, which then enable biological systems to function as needed for the organism to survive. DNA's functioning is enabled by its structure: a double-stranded helix formed via the joining of specific pairs of molecules called 'nucleotides' in specific orders, called...
A new study from University of Minnesota researchers provides an unprecedented look at the causes of poor air quality in the United States and its effects on human health.
Early in the COVID-19 pandemic, researchers found preliminary evidence suggesting that people's blood type might be an important risk factor -- both for being infected by the virus and for falling dangerously ill.But over the past few months, after looking at thousands of additional patients with COVID-19, scientists are reporting a much weaker link to blood type.Two studies -- one at the...
University of Colorado Boulder researchers have used ultra-fast extreme ultraviolet lasers to measure the properties of materials more than 100 times thinner than a human red blood cell.
Large-scale oceanic phenomena are complicated and often involve many natural processes. Tropical instability wave (TIW) is one of these phenomena.
Nuclear magnetic resonance (NMR) is employed in a wide range of applications. In chemistry, nuclear magnetic resonance spectroscopy is in standard use for the purposes of analysis, while in the medical field, magnetic resonance imaging (MRI) is used to see structures and metabolism in the body. Scientists at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), working...

A new spin on the magnetic compression of plasmas could improve materials science, nuclear fusion research, X-ray generation and laboratory astrophysics.
Researchers have found that combining a Western-style high-fat diet with antibiotic use significantly increases the risk of developing pre- inflammatory bowel disease. This combination shuts down the mitochondria in cells of the colon lining, leading to gut inflammation. Mesalazine can help restart the mitochondria and treat pre-IBD condition.
Researchers have discovered how diverse forms of life are able to use the same cellular machinery for DNA transcription.
With the right mix of plants, urban green spaces can be a rich habitat to support diverse pollinators, according to a new study.
Researchers have shown that an enzyme called RNA polymerase (Pol) II drives generation of the building blocks of ribosomes, the molecular machines that manufacture all proteins in cells based on the genetic code.
New research looks at how caregivers address the issues of firearm safety when taking care of someone who has Alzheimer's Disease and Related Dementias (ADRD) and has access to a gun.
Researchers have developed a credit-card sized tool for growing cancer cells outside the human body, which they believe will enhance their understanding of breast cancer metastasis. The device reproduces various environments within the human body where breast cancer cells live. Studying the cells as they go through the process of invasion and metastasis could point the way toward new biomarkers...
While 93 percent of U.S. pediatricians surveyed were aware of the national guidelines on peanut allergy prevention in infants, only 30 percent were fully implementing the recommended practices and 64 percent reported partial implementation, according to the study.
Newfound bacteria that oxidize manganese help explain the geochemistry of groundwater.
