Scientists have made progress in understanding the circadian clock, the 24-hour cycle that synchronizes with light-dark exposure, and how it functions. They developed a new way to study how the circadian clock synchronizes in real time, revealing surprises about the clock’s mechanisms.
Recent discoveries by a team at MIT have revealed that introducing new materials into existing concrete manufacturing processes could significantly reduce this carbon footprint, without altering concrete’s bulk mechanical properties.
For wild animals, false alarms are the most widespread form of misinformation. Deploying camera observatories in a coral reef in French Polynesia, researchers have shown that even in the absence of predators, escape events occur frequently in natural groups of foraging fish but rarely spread to more than a few individuals. These animals form dynamic information exchange networks and adjust their responsiveness to visual cues based on the recent history of sensory inputs from neighbors.
Avian research often focuses on forests as breeding habitats, but scientists are now working to understand the vital role that small forest patches play in migration. For the first time, a team of researchers from Princeton University and the University of Delaware has created a comprehensive map of migratory pathways and stopover locations in the Eastern United States.
Fish can adjust their sensitivity to the actions of others – such as fleeing due to a false alarm – to reduce the risk of responding to misinformation, according to a new study. Other animals, including humans, may also have these decision-making mechanisms.
For mosquito-borne diseases such as dengue fever, the abundance of the insects in places where people gather has long served as the main barometer for infection risk. A new study, however, suggests that the number of “hidden” infections tied to a place, or cases of infected people who show no symptoms, is the key indicator for dengue risk.
The editorial board of the Proceedings of the National Academy of Sciences (PNAS) journal is honoring a pair of Florida State University researchers for their 2022 study which found that childhood exposure to lead has robbed Americans an average of 2.6 IQ points per person.

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.

Using a high-performance computer simulation, the research team found that soil subsidence is unlikely to cause rampant thawing in the future.
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.
