Images  By directly measuring greenhouse gas emissions from an airplane flying over the Gulf of Mexico, a University of Michigan-led team found that the nation's largest offshore fossil fuel production basin has twice the climate warming impact as official estimates.   The work could have bearing on future energy production in the gulf, as decisions about expanding oil and gas harvesting depend on calculations of the climate impact.    While a gap between reported and measured methane emissions in the basin has been noted in the past, this study is believed ...

UNIVERSITY PARK, Pa. — While pollinator populations of many species have plummeted worldwide, one bee species is blowing up the map with its rapid population expansion. The key to this insect’s success? Its passion for pumpkins, zucchinis, and other squashes, and the massive increase in cultivation of these crops across North America over the last 1,000 years. A new study led by Penn State found that the squash bee (Eucera pruinosa) has evolved in response to intensifying agriculture — namely squashes in the genus ...

HOUSTON – (April 3, 2023) – 2D materials get their strength from their atom-thin, sheetlike structure. However, stacking multiple layers of a 2D material will sap it of the qualities that make it so useful. Rice University materials scientist Jun Lou and collaborators at the University of Maryland showed that fine-tuning interlayer interactions in a class of 2D polymers known as covalent organic frameworks (COFs) can determine the materials’ loss or retention of desirable ...

Using cryo-electron microscopy and mass spectrometry, researchers from PSI have deciphered the structure of an ion channel found in the eye while it interacts with the protein calmodulin – a structure that has eluded scientists for three decades. They believe that this interaction could explain how our eyes can achieve such remarkable sensitivity to dim light. Their results are published in the journal PNAS. As you look at the bright screen of your phone or computer, ion channels in your eyes close in response to the light. This is the final step of a biochemical ...

They’re considered some of the strongest materials on the planet, but tapping that strength has proved to be a challenge. 2D materials, thinner than the most delicate onionskin paper, have attracted intense interest because of their incredible mechanical properties. Those properties, however, dissipate when the materials are stacked in multiple layers, thus limiting their usefulness. “Think of a graphite pencil,” says Teng Li, Keystone Professor at the University of Maryland’s (UMD) Department of Mechanical Engineering. “Its core is made of graphite, and graphite ...

A North Carolina State University-led study found it is possible to retrieve forensically relevant information from human DNA in household dust. After sampling indoor dust from 13 households, the researchers were able to detect DNA from household residents over 90% of the time, and DNA from non-occupants 50% of the time. The work could be a way to help investigators find leads in difficult cases. Specifically, the researchers were able to obtain single nucleotide polymorphisms, or SNPs, from the dust samples. SNPs are sites within the genome that vary between individuals –  corresponding ...

Statin therapy does not exacerbate muscle injury, pain or fatigue in people engaging in moderate-intensity exercise, such as walking, according to a study published today in the Journal of the American College of Cardiology. The findings are reassuring for people who experience muscle pain or fatigue from statins but need to engage in physical activity to keep their cholesterol levels low and their hearts healthy. Statins have long been the gold standard for lowering LDL or “bad” cholesterol ...

A new online tool – the first of its kind for plant pathogens – will help researchers across the globe identify, detect and monitor species of Phytophthora, which have been responsible for plant diseases ranging from the devastating 1840s Irish potato famine to sudden oak death that still plagues West Coast oak population.  The new pathogen “tree of life” provides a plethora of information about each of the more than 192 formally described species – including their evolutionary history and relationships within groups – as well as more than 30 other informally described taxa. It also includes ...

Wearable devices such as smart watches could be used to detect a higher risk of developing heart failure and irregular heart rhythms in later life, suggests a new study led by UCL researchers. The peer-reviewed study, published in The European Heart Journal – Digital Health, looked at data from 83,000 people who had undergone a 15-second electrocardiogram (ECG) comparable to the kind carried out using smart watches and phone devices. The researchers identified ECG recordings containing extra heart beats which are usually benign but, if they occur frequently, are linked to conditions such as heart failure and arrhythmia ...

Cold activates a cellular cleansing mechanism that breaks down harmful protein aggregations responsible for various diseases associated with aging. In recent years, studies on different model organisms have already shown that life expectancy increases significantly when body temperature is lowered. However, precisely how this works has still been unclear in many areas. A research team at the University of Cologne’s CECAD Cluster of Excellence in Aging Research has now unlocked one responsible mechanism. The study ‘Cold ...

A very subtle and seemingly random type of eye movement called ocular drift can be influenced by prior knowledge of the expected visual target, suggesting a surprising level of cognitive control over the eyes, according to a study led by Weill Cornell Medicine neuroscientists. The discovery, described Apr. 3 in Current Biology, adds to the scientific understanding of how vision—far from being a mere absorption of incoming signals from the retina—is controlled and directed by cognitive processes. “These ...

AURORA, Colo. (April 3, 2023) – A study published in Frontiers in Surgery finds that people with schizophrenia (SZ) and schizoaffective disorder (SAD) have overall lower surgical risk than people with Parkinson’s disease, which is reassuring when considering potential surgical interventions such as Deep Brain Stimulation (DBS) for the treatment of SZ and SAD. DBS, a procedure that implants electrodes in the deeper structures of the brain connected to generators in the chest, is rare in treating SZ and ...

HOUSTON – (April 3, 2023) – Missing crucial doses of medicines and vaccines could become a thing of the past thanks to Rice University bioengineers’ next-level technology for making time-released drugs. “This is a huge problem in the treatment of chronic disease,” said Kevin McHugh, corresponding author of a study about the technology published online in Advanced Materials. “It’s estimated that 50% of people don't take their medications correctly. With this, you’d give them one shot, and they’d be all set for the next couple of months.” When patients fail to take prescription medicine or take it incorrectly, the costs can ...

New Haven, Conn. — Autosomal dominant polycystic kidney disease (ADPKD) is the most common potentially lethal genetic disease—about a half million people in the United States alone suffer from the condition. There is no cure, but new research could open the door to new gene therapies for treating most cases of the disease. For several decades, researchers have known that mutations in the PKD1 gene, which encodes the polycystin-1 (PC1) protein, can cause the disease in about 80% of cases. However, the protein is too big to be modified through gene therapy strategies. Now, a research ...

Have you ever been so hungry that you become angry, otherwise known as “hangry?” New research by Adam Rosenthal, PhD, assistant professor in the Department of Microbiology and Immunology, has found that some bacteria cells get hangry too, releasing harmful toxins into our bodies and making us sick. Rosenthal and his colleagues from Harvard, Princeton and Danisco Animal Nutrition discovered, using a recently developed technology, that genetically identical cells within a bacterial community have different functions, with some members behaving more docile and others producing the very toxins that make us feel ill. “Bacteria behave much more ...
