Development of a sticker that indicates whether cold-chain food products have gone bad
Can we tell with the naked eye if any cold-chain food products that we have received have gone bad? A cold-chain safety sticker was developed, which indicates whether any cold-chain food products, such as fish, meat, and fruits and vegetables, have spoiled. This cold-chain safety sticker creates an image on it when exposed to room temperature. Room temperature exposure history and time throughout
Ride-hailing linked to more crashes for motorists and pedestrians
Ride-hailing trips increase the number of crashes for motorists and pedestrians at pick-up and drop-off locations, reports a new study from researchers at the Columbia University Mailman School of Public Health. The research is the first to use data for individual ride-hailing trips, rather than comparing cities where ride-hailing is available to those where it is not available.
Men pose more risk to other road users than women
do and they are more likely to drive more dangerous vehicles, reveals the first study of its kind, published online in the journal Injury Prevention.
Doubts cast over accuracy of many popular fertility and pregnancy planning apps
Many popular fertility and pregnancy planning apps may be inaccurate, suggest the results of a scoping review of the available evidence, published online in the journal BMJ Sexual & Reproductive Health.
Clinical trial to assess potential treatment for COVID-19-related respiratory failure
A team of physician-scientists at Beth Israel Deaconess Medical Center are now enrolling patients in a clinical trial to evaluate a common anti-clotting drug for the treatment of COVID-19-positive patients with ARDS. The newly launched trial follows a special report the team published in the Journal of Trauma and Acute Care Surgery that suggested the use of a drug called tPA could reduce deaths am
Potential early biomarker to track development of non-alcoholic fatty liver disease
Research from Rohit N. Kulkarni’s lab at Joslin Diabetes Center has uncovered a biomarker in humans tied to the development of Non-Alcoholic Fatty Liver Disease that might help doctors detect early stages of the disease. The researchers also determined that this biomarker, a protein known as ‘neuronal regeneration related protein’ (or NREP), plays a significant role in the regulation of a pathway
What makes Saturn’s atmosphere so hot
New analysis of data from NASA’s Cassini spacecraft found that electric currents, triggered by interactions between solar winds and charged particles from Saturn’s moons, spark the auroras and heat the planet’s upper atmosphere.
Adding a measure of patient frailty to Medicare payment model could lead to fairer reimbursement for clinicians
Researchers identified a way to measure frailty using patients’ medical claims that more accurately predicts costs-of-care, especially for clinicians with disproportionate shares of frail patients. Adding this measure to Medicare’s value-based payment models could lead to fairer reimbursement for clinicians who care for patients with greater needs. Findings from a retrospective cohort study are pu
Stream pollution from mountaintop mining doesn’t stay put in the water
Since the 1980s, a mountaintop mine in West Virginia has been leaching selenium into nearby streams at levels deemed unsafe for aquatic life. Now, even though the mine is closed, a Duke University-led study finds high concentrations of selenium in emerging stream insects and the spiders that eat them along the banks, an indication that the contaminant moves from water to land as it moves up the fo
Fungi found in cotton can decrease root knot nematode galling
Gregory Sword and colleagues at Texas A&M University inoculated cotton seeds with a diverse array of fungal isolates and tested the resulting seedlings in greenhouse trials for susceptibility to gall formation by root knot nematodes. A majority (77%) of the fungal treatments reduced galling and these reductions were highly repeatable across independent trials.
Researchers use nanotechnology to develop new treatment for endometriosis
Scientists have developed a precise, nanotechnology-based treatment to alleviate the pain and fertility problems associated with endometriosis, a common gynecological condition in women of childbearing age.
Development of new system for combatting COVID-19 that can be used for other viruses
A team working to combat the COVID-19 virus has a system that will unlock researchers’ ability to more quickly develop and evaluate developing vaccines, diagnose infected patients and explore whether or how the virus has evolved. The scientists developed the system by engineering a reverse genetic system for SARS coronavirus 2, or SARS-CoV-2, that is causing the current COVID-19 pandemic. The stud
Compound in fruit peels halts damage and spurs neuronal repair in multiple sclerosis
Ursolic acid, abundant in fruit peels and some herbs, both prevents and repairs neurons in animal models of multiple sclerosis.
Researchers help expand search for new state of matter
Scientists have been striving to establish the existence of quantum spin liquids, a new state of matter, since the 1970s. A recent discovery by University of Arkansas physicists could help researchers solve the mystery and result in the next generation of computing.
Lifestyle trumps geography in determining makeup of gut microbiome
Researchers from Washington University in St. Louis studied the gut microbiomes of wild apes in the Republic of Congo, of captive apes in zoos in the US, and of people from around the world and discovered that lifestyle is more important than geography or even species in determining the makeup of the gut microbiome.
Clemson researchers unraveling role of fungi in early childhood dental health
Clemson University researchers have conducted a study that may someday lead to better cavity prevention measures and treatments. The team examined the oral mycobiome by taking a site-specific approach — looking at both tooth and mouth health — which enabled them to categorize each plaque sample along a continuum. They identified 139 species of fungus that live in human dental plaque, including n
More pavement, more problems
Think your daily coffee, boutique gym membership and airport lounge access cost a lot? There may be an additional, hidden cost to those luxuries of urban living, says a new Johns Hopkins University study: more flooding.For every percentage point increase in roads, parking lots and other impervious surfaces that prevent water from flowing into the ground, annual floods increase on average by 3.3%,
NASA finds heavy rainfall in powerful tropical cyclone Harold
One of NASA’s satellites that can measure the rate in which rainfall is occurring in storms passed over powerful Tropical Cyclone Harold just after it made landfall in Vanuatu in the Southern Pacific Ocean.
Pollen-based ‘paper’ holds promise for new generation of natural components
NTU Singapore scientists have created a paper-like material derived from pollen that bends and curls in response to changing levels of environmental humidity. The ability of this paper made from pollen to alter its mechanical characteristics in response to external stimuli may make it useful in a wide range of applications, from artificial muscles to sensors. Combined with digital printing, it may
