The overarching goal of all carbon capture and storage projects is the same: Keep carbon dioxide (CO2) emissions out of the atmosphere by storing them in the subsurface for good. One way to do that is to inject the CO2 into a reservoir space that’s covered with a big lid – an impermeable caprock that can keep the gas in place and stop any upward flow in its tracks.  That’s the model that petroleum exploration has relied on for decades when searching for oil traps, and it works for both oil and CO2. But according to research led by The University of Texas at Austin’s Bureau of Economic Geology, subsurface ...

Genetic diversity is essential to the survival of a species. It’s easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust offspring with two distinct versions of the species’ genome. Without that combination of different genetic makeups, asexually reproducing species typically suffer from a lack of diversity that can doom them to a limited run on Earth. One such animal should be the clonal raider ant, which produces daughter after genetically identical daughter directly from an unfertilized ovum ...

Scientists at Sanford Burnham Prebys, University of California San Diego and their international collaborators have reported that more types of lung cells can be infected by SARS-CoV-2 than previously thought, including those without known viral receptors. The research team also reported for the first time that the lung is capable of independently mustering an inflammatory antiviral response without help from the immune system when exposed to SARS-CoV-2. This work is especially timely, as cases of COVID-19 are on the rise in the scientists’ hometown of San Diego during a summertime spike. Looking beyond the region, more than half of the states in the country have reported “very ...

Nearly 40 million adults in the U.S. have sleep apnea, and more than 30 million of them use a continuous positive airway pressure (CPAP) machine while sleeping. However, the machines tend to be expensive, clunky and uncomfortable — resulting in many users giving up on using them. High blood pressure is often linked with sleep apnea because the brain works harder to regulate blood flow and breathing during sleep. A recent study at the University of Missouri offers new insight into the underlying mechanisms within the brain contributing ...

Abu Dhabi, July 22, 2024: A team of researchers at NYU Abu Dhabi, led by Professor Sehamuddin Galadari, has discovered that the tumor suppressor protein Prostate apoptosis response-4 (Par-4) can cause a unique type of cell death called ferroptosis in human glioblastoma – the most common and aggressive type of brain tumor – while sparing healthy cells. This new understanding has the potential to inform the development of novel treatments for various hard-to-treat cancers and neurodegenerative diseases. Ferroptosis is triggered by the iron-mediated production of reactive ...
