Study of tundra soil demonstrates vulnerability of ecosystem to climate warming
Findings from one of the first comprehensive field studies by a collaborative team of researchers demonstrate the active layer microbiome of tundra soil was significantly altered after only 1.5 years of experimental warming -- a rapid response demonstrating high sensitivity of this ecosystem to warming. Collectively, the results of this study suggest the vulnerability of permafrost ecosystem carbon to climate warming and the significance of microbial feedbacks in mediating this vulnerability.

Penn study reveals how fish control microbes through their gills
In a new study published in the journal Nature Communications, Oriol Sunyer of the University of Pennsylvanian and colleagues found that fish induce production of a particular antibody in their gills in response to pathogen exposure, work that could lead to improved fish vaccines for aquaculture.

Nearly all US forests threatened by drought, climate change
Forests nationwide are feeling the heat from increasing drought and climate change, according to a study by scientists from 14 research institutions. While the effects have been most pronounced in the West, the team found virtually all US forests are now experiencing some degree of change and are vulnerable to future declines.

Carnegie Mellon, Stanford researchers devise method to safely share password data
An unfortunate reality for cybersecurity researchers is that real-world data for their research too often comes via a security breach. Now computer scientists at Carnegie Mellon and Stanford universities have devised a way to let organizations share statistics about their users' passwords without putting those same customers at risk of being hacked.

Global sea level rose faster from 1900 to 2000 than during any of the previous 27 centuries. Without global warming, the Earth's sea level would have climbed by less than half the observed 20th century increase and might have dropped.

New 'lipidomics' method could bring fast cancer diagnosis
Researchers have developed a new analytical tool for medical applications and biological research that might be used to diagnose cancer more rapidly than conventional methods. The research has implications for the field of lipidomics, which involves the identification and quantification of cellular lipid molecules, how they interact with other components in cells and their role in biological systems.

A research team that included scientists from The Scripps Research Institute has identified a new group of powerful antibodies to fight Ebola virus. The antibodies, isolated from the blood of a survivor of the 2014 Ebola outbreak and the largest panel reported to date, could guide the development of a vaccine or therapeutic against Ebola.

New device may speed up DNA insertion into bacteria
A new microfluidic device developed by MIT engineers may help scientists quickly home in on the electric field 'sweet spot' -- the range of electric potentials that will harmlessly and temporarily open up membrane pores to let DNA in. In principle, the simple device could be used on any microorganism or cell, significantly speeding up the first step in genetic engineering.

Humans settled, set fire to Madagascar's forests 1,000 years ago
Scientists from MIT and the University of Massachusetts at Amherst have found that a widespread and permanent loss of forests in Madagascar that occurred 1,000 years ago was due not to climate change or any natural disaster, but to human settlers who set fire to the forests to make way for grazing cattle.

Study reveals mechanism behind enzyme that tags unneeded DNA
Researchers at Princeton have discovered the two-step process that activates an essential human enzyme, called Suv39h1, which is responsible for organizing large portions of the DNA found in every living cell. Mistakes in packing DNA jeopardizes the stability of chromosomes and can result in severe diseases. Suv39h1 is one of the main enzymes that chemically mark the irrelevant regions of DNA to be compacted by cellular machinery, but little has been known about how it installs its tag until now.

New image analytics may offer quick guidance for breast cancer treatment
For women with the most common type of breast cancer, a new way to analyze magnetic resonance images (MRI) data appears to reliably distinguish between patients who would need only hormonal treatment and those who also need chemotherapy. The analysis may provide women diagnosed with estrogen positive-receptor (ER-positive) breast cancer answers far faster than current tests and, due to its expected low cost, open the door to this kind of testing worldwide.
