Icebergs: Mathematical model calculates the collapse of shelf ice

Shelf ice, as found in Antarctica, refers to giant floating ice sheets that can span thousands of square kilometres. Pieces break off at their edges which form icebergs in the ocean. In order to more effectively predict these break-offs, in a process known as calving, Julia Christmann from the University of Kaiserslautern (TU) has developed mathematical models in cooperation with the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). On the basis of physical factors, it is claimed that these models can be used to predict when and where the ice may collapse. This is important particularly for research teams situated on the ice shelf.

NASA Gets an In-Depth Look at Intensifying Hurricane Harvey

As Hurricane Harvey continued to strengthen, NASA analyzed the storm’s rainfall, cloud heights and cloud top temperatures. NASA’s GPM and Aqua satellite provided information while an animation of GOES-East satellite imagery showed Harvey’s progression toward the Texas coast. 

Harvey's intensification has been aided by movement through an environment that includes low vertical wind shear and the warm waters in the Gulf of Mexico.

A Galápagos seabird's population expected to shrink with ocean warming

Within the next century, rising ocean temperatures around the Galápagos Islands are expected to make the water too warm for a key prey species, sardines, to tolerate. A new study by Wake Forest University biologists, published in PLOS One Aug. 23, uses decades of data on the diet and breeding of a tropical seabird, the Nazca booby, to understand how the future absence of sardines may affect the booby population.

Researchers identify cheaper, greener biofuels processing catalyst

Fuels that are produced from nonpetroleum-based biological sources may become greener and more affordable, thanks to research performed at the University of Illinois’ Prairie Research Institutethat examines the use of a processing catalyst made from palladium metal and bacteria.

Ringing in ears keeps brain more at attention, less at rest, study finds

Tinnitus, a chronic ringing or buzzing in the ears, has eluded medical treatment and scientific understanding. A new study by University of Illinois researchers found that chronic tinnitus is associated with changes in certain networks in the brain, and furthermore, those changes cause the brain to stay more at attention and less at rest.

Researchers predicted when cholera epidemic in Yemen would peak

Hokkaido University scientists has developed a new mathematical model which accurately forecasted that a devastating cholera epidemic in Yemen would peak by early July, the 26th week of 2017 and the cumulative incidence would be the order of 700-800 thousand cases.

Kepler satellite discovers variability in the Seven Sisters

The Seven Sisters, as they were known to the ancient Greeks, are now known to modern astronomers as the Pleiades star cluster – a set of stars which are visible to the naked eye and have been studied for thousands of years by cultures all over the world. Now Dr Tim White of the Stellar Astrophysics Centre at Aarhus University and his team of Danish and international astronomers have demonstrated a powerful new technique for observing stars such as these, which are ordinarily far too bright to look at with high performance telescopes. Their work is published in the Monthly Notices of the Royal Astronomical Society.

SwRI-led study captures science data from Great American Eclipse

Two NASA WB-57F research aircraft successfully tracked the August 21 solar eclipse as part of a NASA project led by Southwest Research Institute (SwRI) to study the solar corona and Mercury’s surface.

The pancreas provides a potential drug candidate for brain disease

Brain functions are maintained by the neural network. Neural network is formed by the connection between the neurite, and this connection is supported by the wrapping of myelin. Demyelination is detected in the patients of several diseases, such as multiple sclerosis, and is associated with neurological dysfunctions. A new study in The Journal of Clinical Investigation by scientists at Osaka University shows that fibroblast growth factor (FGF) 21 promotes remyelination in mice and may be a promising key molecule for treating demyelinating diseases.

Delivers medicine to cancer cells while protecting healthy cells

Cancer of one form or another will affect roughly one-third of all Norwegians. Yet cancer treatments, including chemotherapy, have helped many of those with the disease to go on to live healthy lives.
