Most state legislators say testimony at legislative hearings is influential, though few report that it changes their votes, finds research from the Brown School at Washington University in St. Louis. “Testimony does matter, especially if it is delivered by credited, trustworthy presenters,” said lead author Sarah Moreland-Russell, PhD, assistant research professor at the Brown School.
Why do so many of us cry at the movies? Why do we flinch when Rocky Balboa takes a punch? What’s really happening in our brains as we immerse ourselves in the lives being acted out on screen? These are the questions that Washington University in St. Louis neuroscientist Jeffrey M. Zacks, PhD, explores in his new book, “Flicker: Your Brain on Movies.”
The genome is the instruction book for life. But reading that instruction book and carrying out its directives are controlled by the epigenome, which attaches chemical markers to DNA to activate or silence genes. For the first time, researchers at Washington University School of Medicine and elsewhere have assembled a comprehensive map of the human epigenome.

Children treated for moderate acute malnutrition — a condition suffered by an estimated 35 million children worldwide — experience a disturbingly high rate of relapse and even death in the year following treatment and recovery. But without clear evidence that any one feeding regimen trumps another, the global health community has been divided on how best to treat these children and reduce the 37 percent rate of relapse. A new study led by researchers at Washington University School of Medicine in St. Louis indicates that supplementary feeding for a set time period — 12 weeks — makes an impact but may not be as important as treating children until they reach target weights and measures of arm circumference. The latter is a strategy recommended by the World Health Organization (WHO). However, to the researchers’ surprise, they found that the WHO targets are insufficient and that raising the weight and arm thresholds could significantly lower the rate of relapse.

In the quantum world, the future predicts the past. Playing a guessing game with a superconducting circuit called a qubit, a physicist at Washington University in St. Louis has discovered a way to narrow the odds of correctly guessing the state of a two-state system. By combining information about the qubit's evolution after a target time with information about its evolution up to that time, the lab was able to narrow the odds from 50-50 to 90-10.

In our increasingly digital world, the balance between privacy and free speech is tenuous, at best. But we often overlook the important ways in which privacy is necessary to protect our cherished civil liberties of freedom of speech, thought and belief, says Neil M. Richards, JD, a privacy law expert at Washington University in St. Louis and author of the new book, “Intellectual Privacy: Rethinking Civil Liberties in the Digital Age,” published Feb. 2 by Oxford University Press.
A three-dimensional seismic image of the mantle beneath the Lau Basin in the South Pacific just published in Nature has an intriguing anomaly. The image showed the least magma where the scientists expected to find the most. After considerable debate they concluded that magma with a high water content was flushed so rapidly that it wasn't showing up in the images.
Cyanobacteria are attractive organisms for bio-production but have the drawback that most strains grow slowly. This week scientists at Washington University reported that they have recovered a fast-growing strain of cyanobacteria from a stored culture of a bacteria originally discovered in a creek on the campus of the University of Texas at Austin in 1955.

Here’s some good news for the New Year: According to new research by Washington University in St. Louis and Cornell University, there’s a 1 in 9 chance that a typical American will hit the jackpot and join the wealthiest 1 percent for at least one year in her or his working life. And now the bad news: That same research says only an elite few get to stay in that economic stratosphere – and nonwhite workers remain among those who face far longer odds.
Women whose bodies have high levels of chemicals found in plastics, personal-care products, common household items and the environment experience menopause two to four years earlier than women with lower levels of these chemicals, according to a new study at Washington University School of Medicine in St. Louis. The findings are reported online Jan. 28 in the journal PLOS ONE.
Currently, doctors have to throw away more than 80 percent of donated tissue used for joint replacements because the tissue does not survive long enough to be transplanted. Now, following a recent study, University of Missouri School of Medicine researchers have developed a new technology that more than doubles the life of the tissue. This new technology was able to preserve tissue quality at the required level in all of the donated tissues studied, the researchers found.
