Baltimore (June 9, 2019) - Drinks with added sugar, also known as sugar-sweetened beverages (SSBs), are one of the largest sources of added sugar in the American diet and a major contributor to obesity. SSBs include non-diet sodas, flavored juice drinks, sports drinks, sweetened tea, coffee drinks, energy drinks and electrolyte replacement drinks. Research presented at Nutrition 2019 will examine how various policies could help reduce the consumption of these sugary beverages and improve health.
Baltimore (June 8, 2019) - Eating well, drinking enough water and taking certain supplements have all been shown to positively affect brain function in adults. Less is known about how these factors affect children. At Nutrition 2019, the annual meeting of the American Society for Nutrition, researchers announce new findings on the ways nutrition influences how children think, learn and behave.
Babies born prematurely often face intense medical challenges, including intestines that are underdeveloped or diseased. While an intestine transplant can benefit some patients, many babies are simply too small to endure this procedure. Children's Hospital Los Angeles surgeon Tracy Grikscheit, MD, is a leader in the field of tissue engineering - growing intestines from stem cells.
Bochum-based researchers from the Cluster of Excellence Ruhr Explores Solvation (Resolv), together with cooperation partners from Nijmegen, have investigated how acids interact with water molecules at extremely low temperatures. Using spectroscopic analyses and computer simulations, they investigated the question of whether hydrochloric acid (HCl) does or does not release its proton in conditions like those found in interstellar space. The answer was neither yes nor no, but instead depended on the order in which the team brought the water and hydrochloric acid molecules together.
Call it the "Little Bog of Horrors." In what is believed to be a first for North America, biologists at the University of Guelph have discovered that meat-eating pitcher plants in Ontario's Algonquin Park wetlands consume not just bugs but also young salamanders.
In a paper published this week in the journal Ecology, the research team reports what integrative biologist Alex Smith calls the "unexpected and fascinating case of plants eating vertebrates in our backyard, in Algonquin Park."
SAN ANTONIO - According to preliminary results of a new study, there is a high prevalence of insufficient sleep and symptoms of common sleep disorders among medical center nurses.
Aggregates of the protein alpha-synuclein in the nerve cells of the brain play a key role in Parkinson's and other neurodegenerative diseases. These protein clumps can travel from nerve cell to nerve cell, causing the disease to progress. A team of researchers led by ETH scientists have now discovered how the body can rid itself of these damaging aggregates. Their findings might open up new approaches in the treatment of neurodegenerative diseases.
Sophia Antipolis, 6 June 2019: Urgent action is needed to prevent, detect and treat atrial fibrillation to stop a substantial rise in disabling strokes. That's the main message of a paper published today in EP Europace, a journal of the European Society of Cardiology (ESC),1 during World Heart Rhythm Week.
Mountains have character. The continuous gentle, wavy hills and wide valleys of the Carpathians, Appalachians or lower parts of the Alps contrast strongly with the soaring peaks, ragged ridges and deep ravines of the high Tatra mountains and Pyrenees, which are, in turn, different from the inaccessible, snow-covered Himalayan or Andean giants, along whose slopes flow long tongues of glaciers instead of water. Beneath this great diversity, however, lies a surprisingly similar structure.
Hans Clevers (Hubrecht Institute) and David Tuveson (Cold Spring Harbor Laboratory), experts in the field of stem cells and organoids, have written a review that summarizes the use of organoids in cancer research and shines a light on prospects for the future. These mini-organs can be used to study tumor biology, model tumor development, and to test existing and new therapies in a patient specific way.
ALBUQUERQUE, N.M. -- Steel pipes rust and eventually fail. To preempt disasters, oil companies and others have created computer models to predict when replacement is needed. But if the models themselves go wrong, they can be modified only through experience, a costly problem if detection comes too late.
PULLMAN, Wash - When most people think about air pollution, they think of summertime haze, traffic or smokestack exhaust, wintertime inversions, or wildfire smoke.
They rarely think of the air that they breathe inside their own homes.
Researchers in Punta Tombo, Argentina conducted a study to see whether Magellanic penguins (Spheniscus magellanicus) showed lateralization (handedness) in their behaviors or morphology.
They found no lateralization or mixed results in the population of Magellanic penguins in three individual behaviors: stepping up, swimming, and thermoregulation.
They did find lateralization when penguins fought for dominance with the more aggressive penguin using its left eye and attacking the other penguin's right side in most fights.
The Canadian Rocky Mountains were formed when the North American continent was dragged westward during the closure of an ocean basin off the west coast and collided with a microcontinent over 100 million years ago, according to a new study by University of Alberta scientists.
New research provides insight into the structure of silicon nanocrystals, a substance that promises to provide efficient lithium ion batteries that power your phone to medical imaging on the nanoscale.
The research was conducted by a team of University of Alberta chemists, lead by two PhD students in the Department of Chemistry, Alyx Thiessen and Michelle Ha.
