Seismic Hazard Assessment: Honing the Debate, Testing the Models
Earthquake experts learn that "take a hike" isn't an insult, but a way to resolve hotly debated scientific issues. The scientists found common ground by trekking over it.

For decades, researchers in the genetics field have theorized that the protein spools around which DNA is wound, histones, remain constant in the brain, never changing after development in the womb. Now, researchers from the Icahn School of Medicine at Mount Sinai have discovered that histones are steadily replaced in brain cells throughout life - a process which helps to switch genes on and off. This histone replacement, known as turnover, enables our genetic machinery to adapt to our environment by prompting gene expression, the conversion of genes into the proteins that ...

Washington, D.C., July 1, 2015--The vast majority of consumers recognize that multivitamins, calcium and/or vitamin D supplements can help fill nutrient gaps but should not be viewed as replacements for a healthy diet, according to a new survey conducted on behalf of the Council for Responsible Nutrition (CRN). Conclusions from the survey of more than 2,000 U.S. adults were published in Nutrition Journal in a peer-reviewed article titled, "Consumer attitudes about the role of multivitamins and other dietary supplements: report of a survey," authored by CRN consultant Annette ...

Neurons in a brain region called the medial temporal lobe play a key role in our ability to quickly form memories about real-life events and experiences, according to a study published July 1st in Neuron. By recording from individual neurons in patients, the researchers reveal for the first time in humans the single-cell basis for the creation of episodic memories.
"It was impressive to see how individual neurons signalled the learning of new contextual associations between people and places and that the changes in firing could occur just after one instance," says lead ...

The brain region that helps people tell whether an object is near or far may also guide how emotionally close they feel to others and how they rank them socially, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published today in the journal Neuron. The findings promise to yield new insights into the social deficits that accompany psychiatric disorders like schizophrenia and depression.
The study focused on evidence for the existence of a "social map" in the hippocampus, the part of the brain that remembers locations in physical space ...

If your eyes deceive you, blame your brain. Many optical illusions work because what we see clashes with what we expect to see.
That 3D movie? Give credit to filmmakers who exploit binocular vision, or the way the brain merges the slightly different images from the two eyes to create depth.
These are examples of the brain making sense of the information coming from the eyes in order to produce what we "see." The brain combines signals that reach your retina with the models your brain has learned to predict what to expect when you move through the world. Your brain solves ...

Neurons are a limited commodity; each of us goes through life with essentially the same set we had at birth. But these cells, whose electrical signals drive our thoughts, perceptions, and actions, are anything but static. They change and adapt in response to experience throughout our lifetimes, a process better known as learning.
Research conducted at The Rockefeller University and collaborating institutions has uncovered a new mechanism that makes this plasticity possible. This discovery centers on a specific type of histone, proteins that support DNA and help control ...

WASHINGTON (July 1, 2015) -- Researchers at the George Washington University (GW), led by Michael S. Irwig, M.D., found that men referred for tertiary care for borderline testosterone levels had much higher rates of depression and depressive symptoms than those of the general population.
"In an era where more and more men are being tested for "Low T" -- or lower levels of testosterone -- there is very little data about the men who have borderline low testosterone levels," said Irwig, associate professor of medicine and director of the Center for Andrology at the GW School ...

A University of Texas at Arlington materials science and engineering team has developed a new energy cell that can store large-scale solar energy even when it's dark.
The innovation is an advancement over the most common solar energy systems that rely on using sunlight immediately as a power source. Those systems are hindered by not being able to use that solar energy at night or when cloudy conditions exist.
The UT Arlington team developed an all-vanadium photo-electrochemical flow cell that allows for efficient and large-scale solar energy storage even at nighttime. ...

NASA's Terra satellite and RapidScat instrument showed a slowly developing Tropical Storm Raquel affecting the Solomon Islands on June 30 and July 1. A tropical cyclone warning was in effect for all provinces of the Solomon Islands on July 1.
The RapidScat instrument that flies aboard the International Space Station measures surface winds. When it passed over former Tropical Depression 25P (now Raquel) it gathered data on sustained winds on June 30 from 7:02 to 8:35 UTC (3:02 to 4:35 a.m. EDT). The RapidScat data showed the strongest sustained winds were near 25 meters ...

July 1, 2015 (Washington) - Public attitudes about climate change and energy policy are strongly intertwined with political party affiliation and ideology. But politics play a more modest, or even peripheral, role on public views about other key issues related to biomedical science, food safety and space, according to a new Pew Research Center analysis.
The chart below highlights the wide mix of factors tied to public attitudes across a broad set of 22 science issues. It illustrates the strength of connection between political ...
