COLUMBUS, Ohio - Flavor is the name of the game for scientists who want to optimize food for consumption in ways that improve nutrition or combat obesity.
But there is more to flavor than the substances that meet the mouth. Olfaction, our sense of smell, is a major contributor to how we perceive aromas, especially those related to what we eat.
Champaign, IL, July 19, 2021 - For dairy cows, the transition period--the time between a cow giving birth and beginning to produce milk--brings the greatest possibility of health problems. The current widespread belief is that the effects of excess nonesterified fatty acids (NEFA) in the bloodstream and the ensuing hyperketonemia during this period, coupled with low levels of available calcium, are largely responsible for disorders such as mastitis, metritis, retained placenta, and poor fertility.
UCC-UCM, 13 July. The Giant Galapagos tortoises which live in contact with human farming and tourism activities, or in urbanised zones, have more bacterial resistance to antibiotics than those that live in more isolated ecosystems.
This is the main conclusion of the research published in Environmental Pollution on which Universidad Complutense de Madrid participated together with the Charles Darwin Foundation (FCD), the Institute for Conservation Medicine of the Saint Louis Zoo (ICM), the Centre for Animal Health Research (INIA-CISA) and Universidad Europea de Madrid.
When it comes to transitioning from carbon-based to renewable source energy systems, Americans are on board. They're less keen, however, having these new energy infrastructures--wind turbines or solar farms--built close to their homes, which creates hurdles for policymakers. That's according to a study from University of Georgia researcher Thomas Lawrence.
A serendipitous flythrough of the tail of a disintegrated comet has offered scientists a unique opportunity to study these remarkable structures, in new research presented today at the National Astronomy Meeting 2021.
RESEARCH TRIANGLE PARK, N.C. -- Army-funded research identified a new material that may lead to lightweight armor, protective coatings, blast shields and other impact-resistant structures.
Researchers at the U.S. Army's Institute for Soldier Nanotechnologies at the Massachusetts Institute of Technology, Caltech and ETH Zürich found that materials formed from precisely patterned nanoscale trusses are tougher than Kevlar and steel.
It's no secret that studies show that sexually diverse youth - in particular, lesbian, gay and bisexual (LGB) youth - use more cannabis and experience more mental health challenges than their heterosexual peers.
But what about the changes that occur in the rates of cannabis use: do they precede those related to mental health or is it the other way around? A new study from Université de Montréal offers some answers.
GAINESVILLE, Fla. --- Plants are DNA hoarders. Adhering to the maxim of never throwing anything out that might be useful later, they often duplicate their entire genome and hang on to the added genetic baggage. All those extra genes are then free to mutate and produce new physical traits, hastening the tempo of evolution.
Errors in the metabolic processes of mitochondria are responsible for a variety of diseases such as Parkinson's and Alzheimer's. Scientists needed to find out just how the necessary building blocks are imported into the complex biochemical apparatus of these cell areas. The TOM complex (translocase of the outer mitochondrial membrane) is considered the gateway to the mitochondrion, the proverbial powerhouse of the cell.
Three decades ago, child development researchers found that low-income children heard tens of millions fewer words in their homes than their more affluent peers by the time they reached kindergarten. This "word gap" was and continues to be linked to a socioeconomic disparity in academic achievement.
While parenting deficiencies have long been blamed for the word gap, new research from the University of California, Berkeley, implicates the economic context in which parenting takes place -- in other words, the wealth gap.
The link between on-road traffic and air pollution is well-known, as are the negative health impacts of pollution exposure. However, the many factors that may influence commuters' exposure to pollutants - such as frequency, time, and duration of commute - and the overall impact of commuting remains a matter of on-going scientific discovery.
Although people in early 2020 hoarded toilet paper, washed their hands incessantly, and wouldn't leave home, 11 months later the public pushed the envelope on COVID-19 safety precautions and ignored warnings as time went on, a new University of California, Davis, study suggests.
A recent study in Frontiers in Sustainable Food Systems shows that the fruits of a type of tomato plant send electrical signals to the rest of the plant when they are infested by caterpillars. Plants have a multitude of chemical and hormonal signaling pathways, which are generally transmitted through the sap (the nutrient-rich water that moves through the plant).
A potentially life-saving treatment for heart attack victims has been discovered from a very unlikely source - the venom of one of the world's deadliest spiders.
A drug candidate developed from a molecule found in the venom of the Fraser Island (K'gari) funnel web spider can prevent damage caused by a heart attack and extend the life of donor hearts used for organ transplants.
Tokyo, Japan - Designing materials that have the necessary properties to fulfill specific functions is a challenge faced by researchers working in areas from catalysis to solar cells. To speed up development processes, modeling approaches can be used to predict information to guide refinements. Researchers from The University of Tokyo Institute of Industrial Science have developed a machine learning model to determine characteristics of bonded and adsorbed materials based on parameters of the individual components. Their findings are published in Applied Physics Express.
