A study conducted by researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory reveals that the use of corn ethanol is reducing the carbon footprint and diminishing greenhouse gases.
Rubisco is arguably the most abundant--and most important--protein on Earth. This enzyme drives photosynthesis, the process that plants use to convert sunlight into energy to fuel crop growth and yield. Rubisco's role is to capture and fix carbon dioxide (CO2) into sugar that fuels the plant's activities. However, as much as Rubisco benefits plant growth, it also can operate at a notoriously slow pace that creates a hindrance to photosynthetic efficiency.
New York, NY--May 24, 2021--Whenever you buy something on Amazon, your customer data is automatically updated and stored on thousands of virtual machines in the cloud. For businesses like Amazon, ensuring the safety and security of the data of its millions of customers is essential. This is true for large and small organizations alike. But up to now, there has been no way to guarantee that a software system is secure from bugs, hackers, and vulnerabilities.
Ancient Judeans commonly ate non-kosher fish surrounding the time that such food was prohibited in the Bible, suggests a study published in the peer-reviewed journal Tel Aviv.
This finding sheds new light on the origin of Old Testament dietary laws that are still observed by many Jews today. Among these rules is a ban on eating any species of fish which lacks scales or fins.
Emergency department visits for common conditions such as appendicitis, miscarriage, gallbladder attacks and ectopic pregnancy decreased markedly at the start of the COVID-19 pandemic, but patient outcomes were not worse, found research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.202821.
(10 a.m. EDT May 25, 2021 Denver)-- Adding sintilimab to a regimen of gemcitabine and platinum demonstrates clinical benefit over gemcitabine and platinum alone as first-line therapy in patients with locally advanced or metastatic squamous cell non-small cell lung cancer, according to a study published in the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer.
Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.
WASHINGTON, May 25, 2021 -- For millennia, silver has been utilized for its antimicrobial and antibacterial properties. Although its use as a disinfectant is widely known, the effects of silver's interaction with bacteria on the silver itself are not well understood.
Throughout the pandemic, doctors have seen evidence that men with COVID-19 fare worse, on average, than women with the infection. One theory is that hormonal differences between men and women may make men more susceptible to severe disease. And since men have much more testosterone than women, some scientists have speculated that high levels of testosterone may be to blame.
Egyptian fossil surprise: Fishes thrived in tropics in ancient warm period, despite high ocean tempe
Photos and Map
The Paleocene-Eocene Thermal Maximum, or PETM, was a short interval of highly elevated global temperatures 56 million years ago that is frequently described as the best ancient analog for present-day climate warming.
Fish are among the organisms thought to be most sensitive to warming climates, and tropical sea-surface temperatures during the PETM likely approached temperatures that are lethal to some modern marine fish species, according to some estimates.
Slow slip earthquakes, a type of slow motion tremor, have been detected at many of the world's earthquake hotspots, including those found around the Pacific Ring of Fire, but it is unclear how they are connected to the damaging quakes that occur there. Scientists at The University of Texas at Austin have now revealed the earthquakes' inner workings using seismic CT scans and supercomputers to examine a region off the coast of New Zealand known to produce them.
Road verges cover 1.2% of land in Great Britain - an area the size of Dorset - and could be managed to help wildlife, new research shows.
University of Exeter researchers used Google Earth and Google Street View to estimate that verges account for 2,579 km2 (almost 1,000 square miles) of land.
About 27% of these verges are frequently mown, 41% is wilder grassland, 19% is woodland and the rest is scrub.
There are "significant opportunities" to improve verges by reducing mowing and planting trees, the researchers say.
A security issue in the certification signatures of PDF documents has been discovered by researchers at Ruhr-Universität Bochum. This special form of signed PDF files can be used, for instance, to conclude contracts. Unlike a normal PDF signature, the certification signature permits certain changes to be made in the document after it has actually been signed. This is necessary to allow the second contractual party to also sign the document.
In a new publication from Opto-Electronic Advances; DOI https://doi.org/10.29026/oea.2021.200077, Researchers led by Professor Jeongyong Kim at the Department of Energy Science, Sungkyunkwan University, Suwon, Republic of Korea review light-emitting MXene quantum dots.
Graphene is an ultrathin material characterized by its ultrasmall bending modulus, superflimsiness. Now the researchers at the Nanoscience Center of the University of Jyväskylä have demonstrated how an experimental technique called optical forging can make graphene ultrastiff, increase its stiffness by several orders of magnitude. The research was published in npj 2D Materials and Applications in May 2021.
