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 (10? or higher). Room temperature exposure history and time throughout the cold chain delivery process are indicated but cannot be manually edited.
GALVESTON, Texas - A multidisciplinary team at The University of Texas Medical Branch at Galveston 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.
DURHAM, N.C. -- Since the 1980s, a sprawling mountaintop removal mining complex in southern West Virginia has been leaching pollutants -- such as selenium -- into nearby streams at levels deemed unsafe for aquatic life.
Now, even though the mine is closed, researchers have also found high concentrations of selenium in stream insects when they fly out of the water and the spiders that eat them along the banks, an indication that the contaminant moves from water to land as it makes its way up the food chain.
Beaches in or near England's Marine Protected Areas (MPAs) have the same levels of litter as those in unprotected areas, new research shows.
The study, by the University of Exeter, Natural England and the Marine Conservation Society, found "no difference" in the amount of anthropogenic (caused by humans) litter present inside and outside MPAs.
These MPAs include the 91 Marine Conservation Zones established from 2009 onwards, 256 Special Areas of Conservation (SACs) and 89 Special Protection Areas (for birds).
College students who listened to classical music by Beethoven and Chopin during a computer-interactive lecture on microeconomics -- and heard the music played again that night -- did better on a test the next day than did peers who were in the same lecture, but instead slept that evening with white noise in the background.
Some islands have such low elevation, that mere inches of sea-level rise will flood them, but higher, larger islands will also be affected by changes in climate and an understanding of ancient practices in times of climate change might help populations survive, according to researchers.
"I'm working in a place (Madagascar) where communities around me are sensing, in the span of a few years, that they are seeing climate change," said Kristina Douglass, assistant professor of anthropology, Penn State. "They have seen climate events take out entire reefs."
Every spring in the Northern Hemisphere, the ocean surface erupts in a massive bloom of phytoplankton. Like plants, these single-celled floating organisms use photosynthesis to turn light into energy, consuming carbon dioxide and releasing oxygen in the process. When phytoplankton die or are eaten by zooplankton, the carbon-rich fragments sinks deeper into the ocean, where it is, in turn, eaten by other creatures or buried in sediments. This process is key to the "biological carbon pump," an important part of the global carbon cycle.
Scientists at Singapore's Nanyang Technological University (NTU Singapore) 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, including soft robots, sensors, artificial muscles, and electric generators.
SOME of the tiniest creatures on the planet are vital for the environment. But there is a worldwide fall in insect numbers after an accelerating rate of extinction.
Now, a global group of 30 scientists - including University of Huddersfield lecturer Dr Matt Hill - has highlighted the issue and suggests practical steps that everyone can take to help halt the decline. These include mowing lawns less often, avoiding pesticides and leaving old trees, stumps and dead leaves alone.
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.
Tropical Cyclone Harold developed from a low-pressure system that was observed to the east of Papua New Guinea last week, and has tracked to the southeast, where it has already caused flooding and loss of life in the Solomon Islands.
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%, the researchers found.
The study was published today in Geophysical Research Letters.
Food has something of a "magic hold" on us, as certain flavors and textures can pretty much dictate what we do. Just think about the spicy dish that keeps bringing you back to that remote Chinese restaurant, or the irresistibly creamy but expensive ice-cream at the Italian place on the corner.
But is it only your palate that controls your food choices? It may feel like it, but the answer is no. In fact, much of what is going on happens beyond the walls of your mouth, through interactions between your digestive system and your brain.
What The Study Did: Researchers looked at whether there was a long-term association between using video games at an early age and later weight as a teenager, as well as what role behaviors such as physical activity, the regularity of bedtimes and consuming sugar-sweetened beverages might play. The study was a secondary analysis of data from a study that included 16,000 children born in the United Kingdom.
Authors: Rebecca J. Beeken, Ph.D., of the University of Leeds in Leeds, England, is the corresponding author.
Researchers from the Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore (NUS) have uncovered a genetic variant in a gene called MET that is responsible for more aggressive growth of head and neck, and lung cancers. A further probe into the finding revealed therapeutic strategies that could potentially target this genetic alteration, thereby paving the way for clinicians to develop better and more effective treatments for cancer patients of such profile.
Nuclear bomb tests during the Cold War in the 1950s and 1960s have helped scientists accurately estimate the age of whale sharks, the biggest fish in the seas, according to a Rutgers-led study.
It's the first time the age of this majestic species has been verified. One whale shark was an estimated 50 years old when it died, making it the oldest known of its kind. Another shark was an estimated 35 years old.
