A new study led by Florida State University researchers found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That’s a greater proportion than previously estimated, and it has implications for how much carbon gets sequestered in the ocean and how much moves into the atmosphere.
UC San Diego researchers have identified a strong association between the product of a gene expressed in most cancers and elevated levels of white blood cells that produce antibodies within tumors, suggesting a new therapeutic target.
A pilot trial by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, tested the nasal administration of the drug Foralumab, an anti-CD3 monoclonal antibody.
The injection of bubbles from waves breaking in turbulent and cold high-latitude regions of the high seas is an underappreciated way in which atmospheric gases are transported into the interior ocean. An improved mechanistic understanding of gas exchange in high latitudes is important for several reasons, including to better constrain climate models that are used to predict changes in the ocean inventory of key gases like oxygen and carbon dioxide.
Are people who earn more money happier in daily life? Though it seems like a straightforward question, research had previously returned contradictory findings, leaving uncertainty about its answer.
Differences in genes involved in inflammation, immunity response and neural transmissions begin in childhood and evolve across the lifespan in brains of people with autism, a UC Davis MIND Institute has found.
Cardiovascular medicine, hematology and pulmonary medicine may soon have the first-ever therapies to correct poor tissue oxygenation, a key driver of disease in millions, including peripheral artery disease, sickle cell disease, heart failure, stroke, emphysema and many others. The breakthrough follows a landmark discovery from investigators at Harrington Discovery Institute at University Hospitals (UH) and Case Western Reserve University School of Medicine. The research team showed that a modified version of hemoglobin, termed S-nitrosohemoglobin, senses areas with insufficient oxygen, and then restores blood flow for oxygenation. The study recently published in PNAS.
From astronomical sums of money to opulent superyachts and lavish villas, the assets of the oligarchs providing the political and financial backing for Russian president Vladimir Putin's military ambitions have been publicly and fervently seized by Western nations since Russia's invasion of Ukraine.
International recognition is key to many successful academic careers, but research published today shows female scientific researchers are less internationally mobile than their male counterparts, although the gender gap has shrunk.
Scientists suspect that the red streaks crossing the surface of Jupiter’s moon Europa is a frozen mixture of water and salts, but its chemical signature matches no known substance on Earth. Now researchers have discovered a new type of solid crystal that forms when water and table salt combine in cold, pressurized conditions. Researchers believe the new substance created in a lab on Earth could form at the surface and bottom of these worlds’ deep oceans.
Cedars-Sinai investigators found that women who developed mood and anxiety disorders associated with pregnancy and childbirth had specific altered proteins circulating in their bloodstream in the third trimester. The study is published in the American Journal of Obstetrics & Gynecology.
Irvine, Calif., Feb. 23, 2023 – People often associate Escherichia coli with contaminated food, but E. coli has long been a workhorse in biotechnology. Scientists at the University of California, Irvine have demonstrated that the bacterium has further value as part of a system to detect heavy metal contamination in water. E.

Reporting in the PNAS, UNC School of Medicine researchers made the stunning discovery that telomeres contain genetic information to produce two small proteins, one of which they found is elevated in some human cancer cells, as well as cells from patients suffering from telomere-related defects.
ROCKVILLE, MD – The virus that causes COVID-19, called SARS-CoV-2, uses its spike protein in order to stick to and infect our cells. The final step for the virus to enter our cells is for part of its spike protein to act like a twist tie, forcing the host cell’s outer membrane to fuse with the virus. Kailu Yang, in the lab of Axel Brunger, colleagues at Stanford University, and collaborators at University of California Berkely, Harvard Medical School, and University of Finland have generated a molecule based on the twisted part of the spike protein (called HR2), which sticks itself onto the virus and prevents the spike protein from twisting.
So-called hydrated electrons play a major role in many physical, chemical and biological processes. They are not bound to an atom or molecule and are free in the solution. Since they are only ever created as an intermediate product, they are extremely short-lived.
Canadian researchers show that in Fragile X syndrome, the most common cause of autism, sensory signals from the outside world are underrepresented by cortical pyramidal neurons in the brain. This phenomenon could provide important clues to the underlying cause of the syndrome's symptoms.
Soil is the Earth’s second-biggest carbon storage locker after the ocean, and a research collaboration has shown that it’s moisture, not temperature or mineral content, that’s the key to how well the soil carbon warehouse works.
Antimicrobial resistance represents one of the top 10 global public health threats according to the World Health Organization, and scientists have been scrambling to find new tools to cure the most deadly drug-resistant infections.
A fungus that plagues rice crops worldwide gains entry to plant cells in a way that leaves it vulnerable to simple chemical blockers, a discovery that could lead to new fungicides to reduce the substantial annual losses of rice and other valuable cereals.
Physical activity at the right time of the day seems able to increase fat metabolism, at least in mice.

In findings published in Proceedings of the National Academy of Sciences (PNAS), Saint Louis University researchers and colleagues report that elephants play a key role in creating forests which store more atmospheric carbon and maintaining the biodiversity of forests in Africa. If the already critically endangered elephants become extinct, rainforest of central and west Africa, the second largest rainforest on earth, would gradually lose between six and nine percent of their ability to capture atmospheric carbon, amplifying planetary warming.

UC San Diego researchers identify mutation that causes excessive folding in human brain’s wrinkly cerebral cortex, resulting in diminished cognitive function.
Recent research shows that magnetic fields can spontaneously emerge in a plasma if the plasma has a temperature anisotropy. This mechanism is known as the Weibel instability. This new research is the first to unambiguously observe the Weibel instability in the laboratory. It offers a possible solution to the problem of the origin of the microgauss-level magnetic fields that permeate the galaxies.
