Adding vanilla to sweetened milk makes consumers think the beverage is sweeter, allowing the amount of added sugar to be reduced, according to Penn State researchers, who will use the concept to develop a reduced-sugar chocolate milk for the National School Lunch Program.
"We are utilizing a learned association between an odor and a taste that will allow us to reduce the added sugar content," said Helene Hopfer, assistant professor of food science. "Reducing added sugar in products, just like reducing fat and salt, is the holy grail of food science."
Washington, DC - While the measles vaccine has eliminated the virus in many high-income countries, the global burden of disease persists with an estimated 245,000 measles cases and 68,000 measles-associated deaths worldwide in 2016. India alone accounted for 50 percent of measles cases and 30 percent of measles deaths in 2016. Although low- and middle-income countries (LMICs) account for a large proportion of global measles cases, high-income countries have recently seen a resurgence of measles outbreaks.
Horseshoe crabs that have undergone biomedical bleeding tend to reside in deeper water and approach mating beaches less often, according to a new study published in The Biological Bulletin. In "Effects of the Biomedical Bleeding Process on the Behavior of the American Horseshoe Crab, Limulus polyphemus in Its Natural Habitat," Meghan Owings and her colleagues report the results of an investigation of the behavioral and physiological effects that the bleeding process has on horseshoe crabs that are released back into their natural environment.
Athens, Ga. - For the first time, researchers in the University of Georgia's Regenerative Bioscience Center have used an imaging method normally reserved for humans to analyze brain activity in live agricultural swine models, and they have discovered that pig brains are even better platforms than previously thought for the study of human neurological conditions such as Alzheimer's and Parkinson's.
University of Cincinnati biologist George Uetz long suspected the extravagant courtship dance of wolf spiders made them an easy mark for birds and other predators.
But it was only when he and colleague Dave Clark from Alma College teamed up with former University of Minnesota researcher Tricia Rubi and her captive colony of blue jays that he could prove it.
The total solar eclipse's swath across Wyoming and the United States in August 2017 provided an opportunity for scientists to study a variety of celestial and earthly phenomena, from learning more about the sun's corona to the behavior of animals and plants.
Having aspirations helps us navigate life in a meaningful and fulfilling way, but it can also cause psychological distress when hopes are left unfulfilled.
New Edith Cowan University (ECU) research has found that it's not failing to make progress toward our 'ideal-self' that is problematic but rather the tendency to focus on that lack of progress in a negative way that leads to psychological distress.
In other words, it pays to be kind to yourself, say the key researchers.
University of Alberta researchers have added a new genetic marker to the breast cancer map, helping to expand the list of genetic mutations clinicians can watch for in cancer screenings.
The genetic marker--called rs1429142--was found to confer a higher risk of breast cancer in Caucasian women carrying the genetic variation compared to women without the variation. In premenopausal women, that risk reached as high as 40 per cent. The ability to identify those genes and their variants (called alleles) can be vital to early detection and life-saving treatment.
We all treasure our vacation time and look forward to that time when we can get away from work. With the arrival of summer comes the prime vacation season and along with it one more reasons to appreciate our vacation time: the value to our heart health. While there has been much anecdotal evidence about the benefits of taking a vacation from work, a new study by Syracuse University professors Bryce Hruska and Brooks Gump and other researchers reveals the benefits of a vacation for our heart health.
After a prolonged decline, global hunger is on the rise--affecting more than 820 million individuals in 2017. Additionally, more than 2 billion people suffer from "hidden hunger," which occurs when individuals eat foods that don't provide the nutrients they need to lead healthy, productive lives. Children who suffer from hidden hunger have more difficulty developing to their full mental and physical potential.
A team of researchers from McMaster University has mapped at atomic resolution a toxic protein linked to Alzheimer's disease, allowing them to better understand what is happening deep within the brain during the earliest stages of the disease.
Researchers at the University of Tokyo conducted a census of the Japanese population around 2,500 years ago using the Y chromosomes of men living on the main islands of modern-day Japan. This is the first time analysis of modern genomes has estimated the size of an ancient human population before they were met by a separate ancient population.
A team of University of Copenhagen researchers has compiled the first and only evidence that narwhals and beluga whales can breed successfully. DNA and stable isotope analysis of an anomalous skull from the Natural History Museum of Denmark has allowed researchers to confirm the existence of a narwhal-beluga hybrid.
For nearly thirty years, a strange-looking whale skull has gathered dust in the collections of the Natural History Museum of Denmark. Now, a team of researchers has determined the reason for the skull's unique characteristics: it belongs to a narwhal-beluga hybrid.
New insights into how people first arrived in Australia have been revealed by a group of experts brought together to investigate the continent's deep history.
They used sophisticated modelling to determine not only the likely routes travelled by Aboriginal people tens of thousands of years ago, but also the sizes of groups required for the population to survive in harsh conditions.
Certain cancer cells depend on exporting the metabolite lactate, which accumulates during the generation on energy. Lactate plays an important role in many biochemical and cellular processes. In healthy cells it is produced if our body is not supplied with enough oxygen during intensive exercise. During this anaerobic energy production, lactate accumulates in cells and acidifies them. In certain cancer cells, metabolic processes are disturbed and large amounts of lactate are produced even if the supply with oxygen is sufficient to cover the energy demand.
