Economic and population growth on top of climate change could lead to serious water shortages across a broad swath of Asia by the year 2050, a newly published study by MIT scientists has found.

The study deploys detailed modeling to produce what the researchers believe is a full range of scenarios involving water availability and use in the future. In the paper, the scientists conclude there is a “high risk of severe water stress” in much of an area that is home to roughly half the world’s population.

In a new evolutionary proof of the old adage, 'we are what we eat', Cornell University scientists have found tantalizing evidence that a vegetarian diet has led to a mutation that -- if they stray from a balanced omega-6 to omega-3 diet -- may make people more susceptible to inflammation, and by association, increased risk of heart disease and colon cancer. 

The discovery, led by Drs. Tom Brenna, Kumar Kothapalli, and Alon Keinan provides the first evolutionary detective work that traces a higher frequency of a particular mutation to a primarily vegetarian population from Pune, India (about 70 percent), when compared to a traditional meat-eating American population, made up of mostly Kansans (less than 20 percent). It appears in the early online edition of the journal Molecular Biology and Evolution. 

AU astrophysicists research cosmic particle accelerators with unparalleled energy

Researchers have been mapping the centre of our galaxy in very-high-energy gamma rays using these telescopes - the most sensitive of their kind - for over 10 years. The results were published in the journal Nature on 16 March 2016.

The earth is constantly bombarded by high energy particles from space. Together these particles - protons, electrons and atomic nuclei - are known as cosmic radiation or cosmic rays. The question of which astrophysical sources produce this cosmic radiation has remained a mystery to researchers for over a century. The problem is that the particles are electrically charged and are therefore deflected in interstellar magnetic fields, making it impossible to identify the astrophysical sources that produce them based on their arrival direction. Fortunately, however, the particles interact with light and gas in the neighbourhood of their sources, producing very-high-energy gamma rays that travel to the earth in straight lines. 'These gamma rays allow us to visualise the sources of cosmic radiation in the sky,' says Christopher van Eldik, a professor at FAU's Erlangen Centre for Astroparticle Physics (ECAP) and deputy director of the H.E.S.S. collaboration.

Rising temperatures worldwide are changing not only weather systems, but - just as importantly - the distribution of water around the globe, according to a study published today (March 14, 2016) in the journal, "Scientific Reports."

Analysis of more than 40 years of water samples archived at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire tells a vivid tale of how the sources of precipitation have changed. Over the years, there has been a dramatic increase, especially during the winter, of the amount of water that originated far to the north.

Studies of how climate change might affect agriculture generally look only at crop yields — the amount of product harvested from a given unit of land. But climate change may also influence how much land people choose to farm and the number of crops they plant each growing season. A new study takes all of these variables into account, and suggests researchers may be underestimating the total effect of climate change on the world’s food supply.

Walter and Eliza Hall Institute researchers have uncovered a protein that is key to the development of blood cancers caused by a common genetic error. 

The discovery is a missing piece in the puzzle of understanding how high levels of a protein called MYC drive cancer development, and may to lead to future strategies for early treatment or possibly even prevention of these cancers.

Seventy per cent of human cancers have abnormally high levels of MYC, which forces cells into unusually rapid growth.

For a few weeks in early fall, Georges Bank — a vast North Atlantic fishery off the coast of Cape Cod — teems with billions of herring that take over the region to spawn. The seasonal arrival of the herring also attracts predators to the shallow banks, including many species of whales.

Now researchers from MIT, Northeastern University, the Institute of Marine Research in Norway, and the National Oceanic and Atmospheric Administration, have found that as multiple species of whales feast on herring, they tend to stick with their own kind, establishing species-specific feeding centers along the 150-mile length of Georges Bank. The team’s results are published today in the journal Nature.

A dragonfly barely an inch and a half long appears to be animal world's most prolific long distance traveler – flying thousands of miles over oceans as it migrates from continent to continent – according to newly published research.

Most people know that properly inflated tires can improve a vehicle’s fuel efficiency, but did you know that properly maintained roadways can improve fuel efficiency across an entire pavement network?

Extreme heat can pose several health risks, such as dehydration, hyperthermia and even death, especially during sustained periods of high temperatures. However, a uniform definition of a heat wave doesn’t exist. As a result, public health agencies may be unsure of when to activate heat alerts, cooling centers and other protective measures. A University of Missouri School of Medicine researcher has developed a uniform definition of a heat wave that may help public health agencies prepare for extreme temperatures.
