"Field-grazing animals always eat some earth and dust along with the plants," says Jean-Michel Hatt, professor at the Clinic for Zoo Animals, Exotic Pets and Wildlife. This is particularly the case in dry regions where the wind blows a lot of dust around, and causes a lot of work for the mastica-tory organs. His research team has now shown that various mechanisms prevent excessive abra-sion of the teeth - thus ensuring the animals' survival.
Short and long teeth in the same habitat
Buildings--Pushing the envelope
Scientific journals and funding bodies often require researchers to deposit individual genetic data from studies in research repositories in order to increase data sharing with the aim of enabling the reproducibility of new findings, as well as facilitating new discoveries. However, the introduction of new regulations such as the EU General Data Protection Regulation (GDPR) can complicate this, according to the results of a study to be presented at the annual conference of the European Society of Human Genetics today (Monday).
Oxygen concentrations in both the open ocean and coastal waters have declined by 2-5% since at least the middle of the 20th century.
This is one of the most important changes occurring in an ocean becoming increasingly modified by human activities, with raised water temperatures, carbon dioxide content and nutrient inputs.
Through this, humans are altering the abundances and distributions of marine species but the decline in oxygen could pose a new set of threats to marine life.
One of the main challenges of second-generation biofuel production is identifying enzymes produced by microorganisms for use in a "cocktail" of enzymes to catalyze biomass hydrolysis, in which the enzymes act together to break down the carbohydrates in sugarcane trash and bagasse, for example, and convert them into simple sugars for fermentation.
A new study by the Woods Hole Oceanographic Institution (WHOI) clarifies what influence major currents in the North Atlantic have on sea level along the northeastern United States. The study, published June 13 in the journal Geophysical Research Letters, examined both the strength of the Atlantic Meridional Overturning Circulation (AMOC)--a conveyor belt of currents that move warmer waters north and cooler waters south in the Atlantic--and historical records of sea level in coastal New England.
A new video shows how climate change connected and disconnected Andean "sky islands" during the past million years. The innovative mathematical model used to make the video was based on fossil pollen records and shows how the entire páramo habitat shifted. The model can predict climate change effects in mountainous regions around the world, according to an international team of scientists including authors from the Smithsonian Tropical Research Institute in Panama (STRI).
Every spring, tens of thousands of elk follow a wave of green growth up onto the high plateaus in and around Yellowstone and Grand Teton national parks, where they spend the summer calving and fattening on fresh grass. And every fall, the massive herds migrate back down into the surrounding valleys and plains, where lower elevations provide respite from harsh winters.
Bottom Line: State-level data were analyzed to determine whether Medicaid expansion was associated with changes in rates of physical abuse and neglect of children younger than 6. Medicaid expansion was part of the the Affordable Care Act and prior research suggests it was associated with better financial stability for families and parents' access to mental health care, both risk factors for child maltreatment. This study included data from 2010 through 2016 for 31 states and the District of Columbia that expanded Medicaid and 19 states that didn't.
Some languages -- like English -- are tricky to pick up easily.
Young children learning to read and write English often need to identify patterns in words to be able to read and spell them. For example, knowing the "Magic E" syllable pattern can allow a child to understand why an E at the end of a word like "rate" significantly alters the word's sound from "rat."
Also, knowing that the words "one" and "two" are irregularly spelled helps prevent the child from trying to sound out the underlying sounds when seeing the word in print.
NASA's Terra satellite showed Tropical Cyclone Vayu still lingering near the northwestern coast of India, and its cloud-filled eye remained offshore.
On June 14, 2019, t the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite provided a visible image of Tropical Cyclone Vayu located off western India's Gujarat coast. Animated enhanced infrared satellite imagery revealed a compact area of asymmetric central deep convection (building thunderstorms) with well-organized spiral banding wrapping into a cloud-filled ragged eye.
HOUSTON -- (June 14, 2019) -- Finding a shady refuge to cool off on a hot day could be more than a lifesaver in a warming world. It might save several species that would otherwise go extinct due to global warming, according to an analysis by ecologists at a dozen institutions.

Madrid, Spain, 12-15 June 2019
Madrid, Spain, 14 June 2019: The results of a pilot study presented today at the Annual European Congress of Rheumatology (EULAR 2019) suggest that electro stimulation of one of the nerves connecting the brain to the body (the vagus nerve), could provide a novel treatment approach for patients with rheumatoid arthritis.1
Altering the default order in which foods are shown on the screen, or offering substitutes lower in saturated fat could help customers make healthier choices when shopping for food online, according to a study published in the open access International Journal of Behavioral Nutrition and Physical Activity.
Polymers reinforced with carbon fibers combine strength and low weight. They also boast significant green credentials as they are less resource-intensive during production and use, and they are readily recycled. While the mechanical properties of continuous-fiber laminates are sufficiently competitive for applications in aerospace and automobiles, composites reinforced with short carbon fibers could be attractive for fast-manufacture, and even 3D printing for applications with more moderate strength requirements.
