Fast and curious: Electrons hurtle into the interior of a new class of quantum materials

As smartphones get smarter and computers compute faster, researchers actively search for ways to speed up the processing of information. Now, scientists at Princeton University have made a step forward in developing a new class of materials that could be used in future technologies.

They have discovered a new quantum effect that enables electrons — the negative-charge-carrying particles that make today’s electronic devices possible — to dash through the interior of these materials with very little resistance. (more…)

A plan to share the carbon budget burden

For 20 years, the international community has been unable to agree on a coordinated way to reduce greenhouse gas emissions. J. Timmons Roberts, the Ittleson Professor of Environmental Studies and Sociology, has co-authored a four-step compromise toward emissions reduction that offers “effectiveness, feasibility, and fairness.”

PROVIDENCE, R.I. [Brown University] — Climate change is an issue of urgent international importance, but for 20 years, the international community has been unable to agree on a coordinated way to reduce greenhouse gas emissions. In a “Perspective” piece published in the June issue of Nature Climate Change, J. Timmons Roberts, the Ittleson Professor of Environmental Studies and Sociology, proposes a four-step compromise toward emissions reduction that offers “effectiveness, feasibility, and fairness.” (more…)

A new device deciphers the language of cells

A biomedical engineer listens in on what proteins are saying.

As inventions go, Yale biomedical engineer Rong Fan’s entry into the innovation sweepstakes is not much to look at. Fan’s device, impressively named a single-cell, 45-plex protein secretion measurement platform, seems to be little more than a sandwich of two sheets of clear silicon rubber the thickness of window glass, each sheet a bit smaller than a credit card and bearing a smaller, darker rectangle divided into 14 vertical sections. It has no flashing lights, no intriguing noises, no moving parts, no signs of Applesque high design. Indeed, the object, displayed in Fan’s bustling laboratory on the first floor of the Daniel L. Malone Engineering Center, doesn’t appear to be doing anything at all. (more…)

Our own treacherous immune genes can cause cancer after viral infection

HPV (human papillomavirus) infection is widely known to induce cancer. Many of the mutations that cause this virally-induced cancer are caused by a family of genes that normally combats viral infections, finds new UCL research.

This raises the possibility of developing drugs to regulate the activity of these genes to prevent HPV-associated cancers from developing and reduce the ability of existing cancers to evolve resistance to treatments. (more…)

Berkeley Lab Climate Scientist: More Extreme Heat and Drought in Coming Decades

Lab climate expert is a lead author on the National Climate Assessment.

By the end of this century climate change will result in more frequent and more extreme heat, more drought, and fewer extremes in cold weather in the United States. Average high temperatures could climb as much as 10 or more degrees Fahrenheit in some parts of the country. These are some of the projections made by Lawrence Berkeley National Laboratory (Berkeley Lab) climate scientist Michael Wehner and his co-authors on the National Climate Assessment (NCA). (more…)

Where and how you live strongly influences both the type and number of microbes you carry on your hands, according to a new international study led by scientists at Yale and Stanford.

The research identified and analyzed bacteria on the hands of women in Tanzania and graduate students in the United States, finding that bacterial populations were more similar among the subjects within a country than between subjects of different countries. (more…)

Paying for a crime they didn’t do: 4 percent sentenced to death are likely innocent

ANN ARBOR — Slightly more than 4 percent of people given death sentences in the United States are innocent, according to new peer-reviewed research led by a University of Michigan expert.

The finding shows that the number of innocent people sentenced to death is more than twice the number of inmates exonerated and freed by legal action, according to a study published today in the Proceedings of the National Academy of Sciences. (more…)

NASA Finds Drought May Take Toll on Congo Rainforest

A new analysis of NASA satellite data shows Africa’s Congo rainforest, the second-largest tropical rainforest in the world, has undergone a large-scale decline in greenness over the past decade.

The study, led by Liming Zhou of University at Albany, State University of New York, shows between 2000 and 2012, the decline affected an increasing amount of forest area and intensified. The research, published Wednesday in Nature, is one of the most comprehensive observational studies to explore the effects of long-term drought on the Congo rainforest using several independent satellite sensors.
