North Korea, which just conducted its third nuclear test, is using its weapons program to deter the United States by holding its allies “hostage,” according to Paul Bracken, who teaches management and political science at Yale. (more…)
The increasing production and use of antibiotics, about half of which is used in animal production, is mirrored by the growing number of antibiotic resistance genes, or ARGs, effectively reducing antibiotics’ ability to fend off diseases – in animals and humans.
A study in the current issue of the Proceedings of the National Academy of Sciences shows that China – the world’s largest producer and consumer of antibiotics – and many other countries don’t monitor the powerful medicine’s usage or impact on the environment. (more…)
The long-sought Higgs boson—the particle that endows all elementary particles in the universe with mass—was elusive no longer when scientists at the CERN physics laboratory in Switzerland, discovered it last summer. (more…)
Even in the same animal, not all bites are the same. A new study finds that because the force in a muscle depends on how much it is stretched, an animal’s bite force depends on the size of what it is biting. The finding has direct implications for ecology and evolution.
PROVIDENCE, R.I. [Brown University] — Many animals prefer food — snails, nuts, etc. — that must be cracked and crushed. Scientists have measured the maximum force of their impressive bites before, but a new study introduces a significant subtlety: bite force depends not only on the size and strength of the eater, but also the size of the eatee. That insight has important implications in the lives of predators and prey. (more…)
The Midwest suffered the worst drought in years last summer, and Midwest soil has been suffering from a drought since early 2010. As a result, crops have wilted and farmers have fallen on hard times. Now, a University of Missouri researcher says that it may take at least two years for crops and soil to recover.
Randall Miles, associate professor of soil science at the MU School of Natural Resources, found that soil in the Midwest is dry down to as deep as 5 feet, where the roots of the crops absorb moisture and nutrients. (more…)
Scientists create nanoscale vehicle to battle cancer without harming healthy cells
A tiny capsule invented at a UCLA lab could go a long way toward improving cancer treatment.
Devising a method for more precise and less invasive treatment of cancer tumors, a team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells.

For over 20 years, Microsoft Research’s labs around the world have focused on research across a broad spectrum of topics in computer science. From the start, the organization has invested heavily in pioneering breakthroughs in machine intelligence, including efforts in machine learning and big data. In this interview, Distinguished Scientist Eric Horvitz talks about advances he sees on the horizon, the influence they will have on your daily life, and how insights from big data and developing more intelligent software and services will change the world.
REDMOND, Wash. – Feb. 15, 2013 – At Microsoft Research labs around the world, some very deep thinkers are contemplating big data.
This includes Eric Horvitz, distinguished scientist at Microsoft and co-director of Microsoft Research’s Redmond lab, who was recently elected to the National Academy of Engineering for his work in “computational mechanisms for decision making under uncertainty and with bounded resources.” (more…)
Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study.
The new study showed that pinyon pine seed cone production declined by an average of about 40 percent at nine study sites in New Mexico and northwestern Oklahoma over the past four decades, said CU-Boulder doctoral student Miranda Redmond, who led the study. The biggest declines in pinyon pine seed cone reproduction were at the higher elevation research sites experiencing more dramatic warming relative to lower elevations, said Redmond of CU’s ecology and evolutionary biology department.
