Health care facilities in Black metropolitan counties, Hispanic rural counties and hardest-hit counties were less likely to administer COVID-19 vaccines during initial rollout, a new study finds.

Previously, it has been impossible to capture the high-resolution images of nitrogenase, the only enzyme capable of reducing nitrogen into ammonia, during catalytic action. Now researchers report near-atomic-resolution snapshots of nitrogenase during catalysis using cryogenic electron microscopy.
Scientists have made a major breakthrough in understanding how malaria parasites divide and transmit the disease, which could be a major step forwards in helping to prevent one of the biggest killer infections in the world.
Researchers have developed a machine-learning algorithm that can teach computers to predict how molecules will bind to the surface and how strongly they will bind. The algorithm can assist in predicting efficiently and accurately whether a given material lends itself as a catalyst for chemical reactions involving many different complex molecules.
Researchers have found that that cloudier waters, caused in part by climate change, is making it harder for seabirds to catch fish.
Warmer oceans can lead to large amounts of methane being released from the seabeds, which may amplify climate warming. A new study develops a method to understand the role of microorganisms in increasing emissions of methane from seabeds.
It may feel like an anvil hanging over your head, but that looming deadline stressing you out at work may actually be beneficial for your brain, according to new research. The study found that low to moderate levels of stress can help individuals develop resilience and reduce the risk of developing mental health disorders, like depression and antisocial behaviors. Low to moderate stress can also...
New evidence from Antarctica shows that toxic 'fluorinated forever chemicals' have increased markedly in the remote environment in recent decades and scientists believe CFC-replacements could be among likely sources.
Advancing the potential applications of photoplethysmography, an optical technique used to measure heart rate, in cardiovascular and mental health monitoring requires the analysis of complex nonlinear data from photoplethysmograms (PPGs). Circumventing traditional analytical methods of resolving the complex and dynamic PPG signals, researchers have used nonlinear analysis to determine the accuracy...
The North Pacific Blob, a marine heatwave that began in late 2013 and continued through 2015, was the largest and longest-lasting marine heatwave on record. A new study using data collected by elephant seals reveals that in addition to the well documented surface warming, deeper warm-water anomalies associated with the Blob were much more extensive than previously reported.
The crucial role of insects in the pollination of flowering plants is well known, but algal fertilization assisted by marine animals was hitherto deemed non-existent. A team has now discovered that small crustaceans known as idoteas contribute to the reproductive cycle of the red alga Gracilaria gracilis. The scientists' findings suggest that animal-mediated fertilization is much older than once...
New research finds that specific parts of the brain recognize complex cues in human vocal sounds that do not involve speech, such as crying, coughing or gasping. Insights into the organization of the brain voice-recognition system will enable researchers to better understand neurological disorders where voice perception is altered or missing and even help create better voice assistant devices.
Engineers designed an adhesive patch that produces ultrasound images of the body. The stamp-sized device sticks to skin and can provide continuous ultrasound imaging of internal organs for 48 hours.
Researchers have created protonic programmable resistors -- the building blocks of analog deep learning systems -- that can process data 1 million times faster than the synapses in the human brain. These ultrafast, low-energy resistors could enable analog deep learning systems that can train new and more powerful neural networks rapidly, which could then be used for novel applications in areas...
New research has demonstrated that a novel targeted therapy could be an effective treatment option for a deadly pediatric cancer known as neuroblastoma.
Early exposure to antibiotics kills healthy bacteria in the digestive tract and can cause asthma and allergies, a new study demonstrates.
A team of researchers believe they have identified a cell signaling pathway responsible for the development of esophageal adenocarcinomas, an aggressive form of esophageal cancer that has gradually become more common, even in younger people.
Research has isolated the changes in pain-related brain activity that follow mindfulness training -- pointing a way toward more targeted and precise pain treatment.
Being exposed to work requirements in order to receive food stamps from the U.S. government significantly increased use of mental health care resources for depression and anxiety, a new study has found. The policy's negative effects occurred much sooner for women than men.
Researchers have shown a direct link between vagus nerve stimulation and its connection to the learning centers of the brain. The discovery may lead to treatments that will improve cognitive retention in both healthy and injured nervous systems.
A gene that researchers discovered is responsible for the deadliest type of brain tumor is also responsible for two forms of childhood cancer, the scientists have found. The discovery may open the door to the first targeted treatments for two types of rhabdomyosarcoma, a cancer of the soft tissue that primarily strikes young children.
Researchers estimate the probability of getting COVID-19 on an airplane in the first year of the pandemic surpassed 1 in 1,000 on a totally full flight lasting two hours.
Researchers took a closer look at the current debate over the origin of enzymatic catalytic power and proposes a mechanism that unites the opposing theories.
The catastrophic debris flow that affected Montecito, Calif., in early January, 2018 was the result of a rare confluence of severe events. The Thomas Fire had been raging for weeks in Ventura and Santa Barbara counties, and an unusually strong winter storm dumped half an inch of rain in five minutes on the newly-charred hills above the suburban enclave. With the tough vegetation that holds the...
Researchers have identified nearly 20,000 new or known drug side effects in children across developmental stages and made them freely available to other researchers.
