Published New bioengineered protein design shows promise in fighting COVID-19



A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus responsible for COVID-19. The study focuses on the design and development of a novel protein capable of binding to the spike proteins found on the surface of the coronavirus. The goal behind this innovative approach is twofold: first, to identify and recognize the virus for diagnostic purposes, and second, to hinder its ability to infect human cells.
Published New simpler and cost-effective forensics test helps identify touch DNA



Research has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and being able to identify DNA from a primary contact -- someone who may have committed the crime -- as well as secondary DNA that was inadvertently and indirectly transferred through touch.
Published Sulfur and the origin of life



A new study shines a spotlight on sulfur, a chemical element that, while all familiar, has proved surprisingly resistant to scientific efforts in probing its role in the origin of life.
Published Tryptophan in diet, gut bacteria protect against E. coli infection



Gut bacteria and a diet rich in the amino acid tryptophan can play a protective role against pathogenic E. coli, which can cause severe stomach upset, cramps, fever, intestinal bleeding and renal failure.
Published Cheers! NASA's Webb finds ethanol, other icy ingredients for worlds



What do margaritas, vinegar, and ant stings have in common? They contain chemical ingredients that NASA's James Webb Space Telescope has identified surrounding two young protostars known as IRAS 2A and IRAS 23385. Although planets are not yet forming around those stars, these and other molecules detected there by Webb represent key ingredients for making potentially habitable worlds.
Published Do astronauts experience 'space headaches'?



Space travel and zero gravity can take a toll on the body. A new study has found that astronauts with no prior history of headaches may experience migraine and tension-type headaches during long-haul space flight, which includes more than 10 days in space.
Published Study shows important role gut microbes play in airway health in persons with cystic fibrosis



Findings from a new study reflect the important role that the gut microbiome (communities of bacteria) plays in the airway health of persons with cystic fibrosis.
Published Giant volcano discovered on Mars



A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars' equator in plain sight. Its discovery points to an exciting new place to search for life, and a potential destination for future robotic and human exploration.
Published Steroid drugs used for HRT can combat E. coli and MRSA



Researchers have combined computational and microbiology laboratory approaches to identify existing drugs that can be repurposed to combat antibiotic-resistant bacterial infections. This research has revealed that a class of steroid drugs currently used in hormone replacement therapy (HRT) can also stop the growth of antibiotic-resistant E. coli and effectively kill MRSA.
Published Simple trick could improve accuracy of plant genetics research



Researchers have published a simple trick that improves the accuracy of techniques that help us understand how external variables -- such as temperature -- affect gene activity in plants.
Published Milk to the rescue for diabetics? Cow produces human insulin in milk



An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk. The advancement could herald a new era in insulin production, one day eliminating drug scarcity and high costs for people living with diabetes.
Published A simple and robust experimental process for protein engineering



A protein engineering method using simple, cost-effective experiments and machine learning models can predict which proteins will be effective for a given purpose, according to a new study.
Published Who knew that coprophagy was so vital for birds' survival?



New research explains how eating feces (known as coprophagy) shapes wild birds' digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources.
Published Scientists find weak points on Epstein-Barr virus



Studies of interactions between two lab-generated monoclonal antibodies (mAbs) and an essential Epstein-Barr virus (EBV) protein have uncovered targets that could be exploited in designing treatments and vaccines for this extremely common virus.
Published How a natural compound from sea squirts combats cancer



Trabectedin, a promising drug derived from the sea squirt Ecteinascidia turbinata, has shown potential in combating cancers resistant to conventional treatments. However, its precise mechanism of action has remained elusive -- until now.
Published Scientists propose new theory that explains sand ripples on Mars and on Earth



Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?
Published Maternal obesity may promote liver cancer



Obesity, which could reach 50% of the population in certain developed countries by 2030, is a major public health concern. It not only affects the health of those who suffer from it, but could also have serious consequences for their offspring. Scientists have studied the impact of maternal obesity on the risk of developing liver disease and liver cancer. Using an animal model, the team discovered that this risk was indeed much higher in the offspring of mothers suffering from obesity.
Published Researchers uncover protein responsible for cold sensation



Researchers have identified the protein that enables mammals to sense cold, filling a long-standing knowledge gap in the field of sensory biology.
Published 'Molecular Rosetta Stone' reveals how our microbiome talks to us



Researchers have uncovered thousands of previously unknown bile acids, a type of molecule used by our gut microbiome to communicate with the rest of the body.
Published Higher bacterial counts detected in single-serving milks, researchers report



Scientists have detected higher bacterial counts in commercial, paperboard single-serving containers two weeks after processing than milk packaged in larger containers from the same facilities.
