Climate Change May Contribute to Rising Rates of Chronic Kidney Disease

• Chronic kidney disease that is not associated with traditional risk factors appears to be increasing in rural hot communities as worldwide temperature progressively rises. • The condition has likely increased due to global warming and an increase in extreme heat waves, and it is having a disproportionate impact on vulnerable populations.

Why Vultures Matter – and What We Lose if They’re Gone

The primary threat to vultures is the presence of toxins in the carrion they consume. Losses of vultures can allow other scavengers to flourish. Proliferation of such scavengers could bring bacteria and viruses from carcasses into human cities.

A team of researchers led by McMaster University’s Charu Kaushic has revealed for the first time how estradiol, a female sex hormone present during the menstrual cycle and found in oral contraceptives, may work to protect women against sexually transmitted viral infections.

Researchers have made a giant leap forward in taking snapshots of these ultrafast reactions in a bacterial light sensor. Using the world’s most powerful X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory, they were able to see atomic motions as fast as 100 quadrillionths of a second – 1,000 times faster than ever before.

Come to Think of It or Not: Study Shows How Memories Can Be Intentionally Forgotten

114811_web.jpg

Context plays a big role in our memories, both good and bad. Bruce Springsteen's "Born to Run" on the car radio, for example, may remind you of your first love -- or your first speeding ticket. But a Dartmouth- and Princeton-led brain scanning study shows that people can intentionally forget past experiences by changing how they think about the context of those memories.

Getting a Better Measure of Spin with Diamond

illustration_D6-01.png

Diamonds are one of the most coveted gemstones. But while some may want the perfect diamond for its sparkle, physicists covet the right diamonds to perfect their experiments. The gem is a key component in a novel system that enables precision measurements that could lead to the discovery of new physics in the sub-atomic realm — the domain of the particles and forces that build the nucleus of the atom.

From Genome Research: Venus Flytrap Exploits Plant Defenses in Carnivorous Lifestyle

114392_web.jpg

Venus flytraps have fascinated biologists for centuries, however, the molecular underpinnings of their carnivorous lifestyle remain largely unknown. In a study published online today in Genome Research, researchers characterized gene expression, protein secretion, and ultrastructural changes during stimulation of Venus flytraps and discover that common plant defense systems, which typically protect plants from being eaten, are also used by Venus flytraps for insect feeding.

IU Data Scientists Launch Free Tools to Analyze Online Trends, Memes

xvzqkt0yak_actual-3.jpg

The power to explore online social media movements -- from the pop cultural to the political -- with the same algorithmic sophistication as top experts in the field is now available to journalists, researchers and members of the public from a free, user-friendly online software suite released today by scientists at Indiana University. The Web-based tools, called the Observatory on Social Media, or "OSoMe" (pronounced "awesome"), provide anyone with an Internet connection the power to analyze online trends, memes and other online bursts of viral activity. The tools are online at online at osome.iuni.iu.edu.

Lung Tumors Hijack Metabolic Processes in the Liver, UCI Study Finds

lungcancer_160427_05_sz.jpg

University of California, Irvine scientists who study how circadian rhythms – our own body clocks – control liver function have discovered that cancerous lung tumors can hijack this process and profoundly alter metabolism. Their research, published online today in Cell, is the first showing that lung adenocarcinoma can affect the body clock’s sway over lipid metabolism and sensitivity to insulin and glucose.

Antibody Appears to Attack Cancer Cells, Leaving Other Cells Unscathed

Duke-Health-Cancer-Antibody.jpeg

A research team from Duke Health has developed an antibody from the body’s own immune system that preferentially attacks cancer cells. The antibody works by targeting a natural defense mechanism that cancer tumors exploit. Cells in the body essentially use a home security system that relies on certain proteins to protect the cell surface and keep it safe. These proteins help the cell avoid injury and even death from unwanted activation of the immune system.

Testing Non-Breast/Ovarian Cancer Genes in High-Risk Women Leaves More Questions Than Answers

Running large, multi-gene sequencing panels to assess cancer risk is a growing trend in medicine as the price of the technology declines and more precise approaches to cancer care gain steam. The tests are particularly common among breast and ovarian cancer patients. However, questions remain about the growing list of mutations and their suspected, but unproven association with breast and ovarian cancer risk.

UCI Astronomers Determine Precise Mass of a Giant Black Hole

Astronomers from the University of California, Irvine and other universities have derived a highly precise measurement of the mass of a black hole at the center of a nearby giant elliptical galaxy. Working with high-resolution data from the Atacama Large Millimeter/submillimeter Array in Chile, the scientists were able to determine the speed of a disk of cold molecular gas and dust orbiting the supermassive black hole at the heart of galaxy NGC 1332. From there, they calculated the black hole's mass to be 660 million times greater than that of the Sun.

Invaluable as markers for monitoring photosynthesis and other energy-related processes in living cells, green fluorescent proteins are vital in high-resolution imaging studies. Scientists found that when water is added to the protein’s chromophore, the fluorescence is more stable.
