The effects of obesity mirror those of aging

R esearchers argue that obesity should be considered premature aging. They look at how obesity predisposes people to acquiring the kinds of potentially life-altering or life-threatening diseases normally seen in older individuals: compromised genomes, weakened immune systems, decreased cognition, increased chances of developing type 2 diabetes, Alzheimer's disease, cardiovascular disease, cancer...

Snowstorm to target interior Northeast as I-95 corridor remains in snow drought

A large storm will spread rain across the Interstate 95 corridor in the Northeast through Wednesday, but like so many others this winter, the storm will send snow elsewhere. In this case, forecasters say it will whiten parts of the central Appalachians and bring the heaviest amounts to the northern tier of the region.The same storm system will produce a swath of heavy snow over parts of the...

Simple self-charging battery offers power solutions for devices

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved output power for batteries. Researchers report making their very simple battery with two different metals, as electrodes and a lithium or sodium glass electrolyte between them.

Ulcerative colitis linked to missing gut microbes

About 1 million people in the United States have ulcerative colitis, a serious disease of the colon that has no cure and whose cause is obscure. Now, a study by Stanford University School of Medicine investigators has tied the condition to a missing microbe.

Social banks rely on their motivated investors

The main reason for the existence of social banks is to fund other social enterprises. On that basis, Simon Cornée from the University of Rennes 1, Panu Kalmi from the University of Vaasa and Ariane Szafarz from the Université Libre de Bruxelles propose that social banks can operate profitably and still lend to their borrowers at attractive interest rates when their owners and depositors accept...

When it comes to conservation, ditch the 'canary in the coal mine'

With habitat loss threatening the extinction of an ever-growing number of species around the world, many wildlife advocates and conservation professionals rely on the proverbial 'canary in the coal mine'—monitoring and protecting a single representative species—to maintain healthy wildlife biodiversity.

Observation of non-trivial superconductivity on surface of type II Weyl semimetal

Topological superconductors, with bulk superconducting gap and Majorana fermion states on the surface or edge, are one of the most sought after quantum materials. Topological superconductivity is of fundamental importance with potentially powerful applications in topological quantum computation. The discovery of Weyl semimetals—in which the conduction and valence bands contact only at Weyl...

Genetic resistance to lethal virus found in key farmed fish species

Resistance to a deadly disease that is affecting the second most farmed fish in the world has been found to be mainly due to differences in genes between families of the same fish. The breakthrough could help protect stocks of Tilapia fish, which is an important food source in Africa, Asia and South America and worth nearly $10 billion to the global economy.

Spring is coming earlier in US this year than it has since 1896

This geostationary operational environmental satellite image (GOES) East image was captured on March 20, 2019, at 8 a.m. ET prior to the equinox. (Photo courtesy NOAA National Environmental Satellite, Data, and Information Service (NESDIS)) Those hoping for an early spring this year will get their wish.The vernal equinox will take place on March 19 throughout the entire United States including...

Merging storms to spare Chicago its biggest snowfall of the season

Winter storm watches were in effect Tuesday from Peoria, Illinois, to Detroit and Toledo, Ohio, as two storms prepare to merge and unleash one of the biggest snowfalls of the season to the region.The dynamic storm has shifted its track farther to the southeast, causing the area's heaviest snow to pivot. Detroit is among the areas in the new bull's-eye.Back on Nov. 11 and 12, a storm...
