Why Both Stimulating And Blocking GLP-1R Helps People Lose Weight
Understanding which brain circuits respond to weight loss medications and how they behave could lead to better weight loss with fewer side effects.
Marine Biology 10,000 Feet Above Sea Level
Mountains sure aren´t what they used to be. Take the Dolomites in the Veneto Region of Italy and Austria; 140 to 90 million years ago, they were part of the sea floor rather than mountains. Over millions of years, deposits were then formed from calcareous shells of marine life from the Mesozoic era. Tectonic forces later caused these sediments to rise upward to the mountaintops of today´s well-known and popular Southern Alps. The mountain range contains one of the most complete and most accessible geological records - also being one of the richest in fossils - from the Cretaceous period in Europe. This record was scientifically analyzed in-depth for the first time within the framework of a project supported by the Austrian Science Fund FWF.
Women And STEM: Maybe Our Sex Hormones Are Sexist
Bias in science academia is a big topic, but it's selective. If there are fewer women, it is regarded as a hostile environment but if there are no Republicans that is their choice. Penn State researchers have added something new into the mix - hormones. If you are a woman who wanted to be a physicist, you may have been fighting your own sex hormones to do it, they say. They did it by looking at people's interest in occupations that exhibit sex differences in the general population and are relevant to science, technology, engineering and mathematics (STEM) careers.
Tibet: Cradle Of The Ice Age Giants?
A new oldest woolly rhino fossil in Tibet suggests some giant mammals evolved there before the beginning of the Ice Age, but it leaves a lot of questions about where these giants came from and how they acquired their adaptations for life in a cold environment.A team of geologists and paleontologists led by Xiaoming Wang from the Natural History Museum of Los Angeles County (NHM) and Qiang Li of Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, uncovered a complete skull and lower jaw of a new species of woolly rhino (Coelodonta thibetana) in the foothills of the Himalayas at the southwestern Tibetan Plateau.
On The Path Toward A "Star Trek"-Style Sick Bay
A non-invasive disease detection facility has been unveiled for use in Leicester Royal Infirmary's A&E department. It will detect the "sight, smell and feel" of disease without the use of invasive probes, blood tests, or other time-consuming and uncomfortable procedures.If you're thinking that sounds like Dr. McCoy's tricorder on the "Star Trek" television series, you are right. But right now it's more like his sick bay than a portable device.The University of Leicester have three different types of cutting-edge technology in combination under a range of situations. All the methods are non-invasive and could speed up diagnosis.
SDSS J102915+172927 - The Star That Shouldn't Exist
SDSS J102915+172927 is in the constellation of Leo. It has a mass smaller than that of the Sun and is probably more than 13 billion years old and has been found to have the lowest amount of elements heavier than helium (what astronomers call "metals") of all stars yet studied.The mystery? It shouldn't exist.
Rossby Waves - What Russian Fires And Pakistan Floods Have In Common
Planetary waves, named Rossby waves because they were discovered by
Carl-Gustav Rossby in the 1930s,
are intriguing natural phenomena that travel from East to West.A new NASA study suggests two of the most destructive natural disasters of 2010 were completely natural and closely linked even though they occurred 1,500 miles apart.
Not All Sunshine For Solar Power - Lead Pollution Crisis In Developing Countries
As solar power continues to grow in popularity, science issues like pollution are being swept under the rug in hopes future technology will solve it before it becomes a crisis, much like with ethanol, MTBE, PBDEs and other once-popular efforts environmental lobbyists spent millions promoting.Chris Cherry, assistant professor in civil and environmental engineering at University of Tennessee-Knoxville, says solar power's reliance s on lead batteries has the potential to release more than 2.4 million tons of lead pollution in China and India, a pattern likely to be repeated throughout much of the developing world, such as in Africa.
Nitrogen Cycle To The Rescue? Bedrock Nitrogen May Help Against Climate Change
It seems trees have the ability to tap into nitrogen found in rocks, boosting the trees’
growth and their ability to pull more carbon dioxide from the
atmosphere.That's good news in the short term. Carbon dioxide is the greenhouse gas most are worried about so that means nitrogen in rocks can significantly affect how rapidly the earth will warm in
the future, the U.C. Davis researchers say. Nitrogen, found in such vital molecules as DNA and protein, is necessary for all life and is used worldwide as a fertilizer for food crops. It is the nutrient that most often limits plant growth in natural ecosystems.
Near Orion Nebula, Stellar Jets Show The Birth Of A Young Star
1350 light-years from Earth, near the Orion Nebula, a bright, clumpy jet called called Herbig-Haro 34 (HH 34) ejected from a young star has changed over time - a signpost of star birth. Stars aren't shy about sending out birth announcements. They fire off energetic jets of glowing gas travellng at supersonic speeds in opposite directions through space. Although astronomers have looked at still pictures of stellar jets for decades, now they can watch movies, thanks to the NASA/ESA Hubble Space Telescope.
Smooth Like A Robot? An Algebraic Approach To Better Movement
A research project aims to improve the control of robot movements with the help of new mathematical approaches.
New developments in the areas of motion planning, computer-aided design and algebraic geometry aim to help in the identification of situations in which a collision may occur for a robot and the planning of an optimal motion path. Algebraic methods for the control of robot motions are being used for the first time in combination with numeric and geometric methods.
Chaos In A Coffee Stain
The ring-shaped stains of tiny dissolved particles, like a coffee stains from the bottom of a cup, that develop after a liquid has evaporated hold a physics mystery - while the particles on the outside of the ring are neatly organized, chaos reigns on the inside of the ring where the particles seem to have collected in a great hurry.
Asian Longhorned Beetle Puts New England Maple Trees At Risk
Results from the first study of the Asian longhorned beetle (ALB) in forests show that the invasive insect can easily spread from tree-lined city streets to neighboring forests. Successful ALB eradication efforts in Chicago, and ongoing eradication efforts in Boston, New York, and other U.S. cities have focused exclusively on urban street trees and the ongoing ALB infestation in Worcester, Mass., is the only outbreak so far that has allowed the beetle to invade nearby closed-canopy forests.
