When the mouse and human genomes were catalogued more than 10 years ago, an international team of researchers set out to understand and compare the "mission control centers" found throughout the large stretches of DNA flanking the genes. Their long-awaited report, published Nov. 19 in the journal Nature suggests why studies in mice cannot always be reproduced in humans. Importantly, the scientists say, their work also sheds light on the function of DNA’s regulatory regions, which are often to blame for common chronic human diseases.
Microbiologists at NYU Langone Medical Center say they have what may be the first strong evidence that the natural presence of viruses in the gut—or what they call the ‘virome’—plays a health-maintenance and infection-fighting role similar to that of the intestinal bacteria that dwell there and make up the "microbiome."
The intense farming practices of the "Green Revolution" are powerful enough to alter Earth’s atmosphere at an ever-increasing rate, boosting the seasonal amplitude in atmospheric carbon dioxide to about 15 percent over the past five decades.
In a study that identifies a new, "direct fingerprint" of human activity on Earth, scientists have found that agricultural crops play a big role in seasonal swings of carbon dioxide in the atmosphere.
Each year in the Northern Hemisphere, levels of atmospheric carbon dioxide (CO2) drop in the summer as plants inhale, and then climb again as they exhale and decompose after their growing season. Over the past 50 years, the size of this seasonal swing has increased by as much as half, for reasons that aren’t fully understood. Now a team of researchers led by Boston University scientists has shown that agricultural production may generate up to a quarter of the increase in this seasonal carbon cycle, with corn playing a leading role.
With temperatures dipping, homeowners are firing up their heaters. But systems that require heating oil release fine particles outside that could have harmful health effects. Regulations to curb these emissions in New York City, however, could save hundreds of lives, a new study has found. The report in the ACS journal Environmental Science & Technology may have ramifications for the entire northeast, the country’s largest consumer of heating oil.

(Phys.org) —A Georgia Tech professor is offering an alternative to the celebrated "Turing Test" to determine whether a machine or computer program exhibits human-level intelligence. The Turing Test – originally called the Imitation Game – was proposed by computing pioneer Alan Turing in 1950. In practice, some applications of the test require a machine to engage in dialogue and convince a human judge that it is an actual person.
Inspired perhaps by Harry Potter’s invisibility cloak, scientists have recently developed several ways—some simple and some involving new technologies—to hide objects from view. The latest effort, developed at the University of Rochester, not only overcomes some of the limitations of previous devices, but it uses inexpensive, readily available materials in a novel configuration.

Approximately 40 percent of the earth’s surface is covered by drylands in which average annual precipitation is lower than evaporation. The changes projected to unfold in these areas in the course of climate change are alarming. Greater variations in annual and seasonal precipitation will lead to more frequent droughts and, presumably, longer drought periods. This means that drylands are among those areas most severely affected by climate change.

(Phys.org) —The Sun may be playing a part in the generation of lightning strikes on Earth by temporarily ‘bending’ the Earth’s magnetic field and allowing a shower of energetic particles to enter the upper atmosphere.
Truth shines a light into dark places. But sometimes to find that truth in the first place, it’s better to stay in the dark. That’s what recent findings at the National Institute of Standards and Technology (NIST) show about methods for testing the safety of nanoparticles. It turns out that previous tests indicating that some nanoparticles can damage our DNA may have been skewed by inadvertent light exposure in the lab.
During a routine stop at the grocery store, Miles Medina MS ’14 had a random thought. Why couldn’t the store grow the very produce it sells on its roof?
Are the political parties really all that different from one another? Can politicians rig the vote in their favor by filling in their own profiles on the voting recommendation website "smartvote"? Two EPFL PhD students applied data analysis methods to information collected from the Swiss democratic system. Their results won them a "best paper award" in this year’s ACM Conference on Online Social Networks, held in Dublin, Ireland. Their next goal is to predict the outcome of a vote using partial results along with data from preceding ballots.
