Scientists attending a workshop at Cold Spring Harbor Laboratory slipped the leash of scientific caution and tried to imagine what they would do if they could redesign plants at will. The ideas they dreamed up may make the difference between full bellies and empty ones in the near future when population may outrun the ability of traditional plant breeding to increase yields.

Infections with one of the most troublesome and least understood antibiotic-resistant “superbugs” are increasing. But now scientists at Washington University School of Medicine in St. Louis have shown the bacteria, A. baumannii, can naturally relinquish its defenses against antibiotics.
Few people today would dare call President Richard Nixon a radical liberal. But 44 years ago, he proposed a health plan that went far beyond what today’s Affordable Care Act includes. After the first plan failed, he did it again three years later. A new paper compares the reality – and rhetoric – of both Nixon’s plans and the current law.
Groundbreaking work at two Department of Energy national laboratories has confirmed plutonium’s magnetism, which scientists have long theorized but have never been able to experimentally observe.
Researchers at the University of California, San Diego and the School of Medicine have found that the three-dimensional shape of the cerebral cortex – the wrinkled outer layer of the brain controlling many functions of thinking and sensation – strongly correlates with ancestral background. The study opens the door to more precise studies of brain anatomy going forward and could eventually lead to more personalized medicine approaches for diagnosing and treating brain diseases.
More than a quarter of the rain and snow that falls on continents reaches the oceans as runoff. Now a new study helps show where the rest goes.

The distraction is comparable to the effects seen when actually using a cell phone to make calls or send text messages.
Developing any habit starts with a routine. The trick is making exercise a habit that is hard to break. A new Iowa State University study shows that may be easier to accomplish by focusing on cues that make going to the gym automatic.

How much a child’s pupil dilates in response to seeing an emotional image can predict his or her risk of depression over the next two years, according to new research from Binghamton University.
A stroke happens in an instant. And many who survive one report that their brain never works like it once did. But new research shows that these problems with memory and thinking ability keep getting worse for years afterward – and happen faster than normal brain aging.
When electrons move in a phosphorus transistor, they do so only in two dimensions, according to a study published in Nature Communications . The finding suggests that black phosphorus could help engineers surmount one of the big challenges for future electronics: designing energy-efficient transistors.
Researchers have used an X-ray laser to record, in detail never possible before, the microscopic motion and effects of shock waves rippling across diamond. The technique, developed at the Department of Energy's SLAC National Accelerator Laboratory, allows scientists to precisely explore the complex physics driving massive star explosions, which are critical for understanding fusion energy, and to improve scientific models used to study these phenomena.
Studying brain scans and cerebrospinal fluid of healthy adults, scientists have shown that changes in key biomarkers of Alzheimer's disease during midlife may help identify those who will develop dementia years later, according to new research.
Imagine a fleet of driverless taxis roaming your city, ready to pick you up and take you to your destination at a moment’s notice. While this may seem fantastical, it may be only a matter of time before it becomes reality. And according to a new study from Lawrence Berkeley National Laboratory, such a system would both be cost-effective and greatly reduce per-mile emissions of greenhouse gases.
Researchers at the University of Adelaide have discovered a new method for culturing stem cells which sees the highly therapeutic cells grow faster and stronger.

As floodwaters surge along major rivers in the midwestern United States, a new study from Washington University in St. Louis suggests federal agencies are underestimating historic 100-year flood levels on these rivers by as much as five feet, a miscalculation that has serious implications for future flood risks, flood insurance and business development in an expanding floodplain.
The first study of its kind measuring the brain’s role in mediating caloric intake following alcohol consumption among women shows that alcohol exposure sensitizes the brain’s response to food aromas and increases caloric intake.

New research led by the University of Adelaide hopes to close the debate on whether a major mud volcano disaster in Indonesia was triggered by an earthquake or had man-made origins.
Most of the seeds and skin from grapes used for wine production winds up in waste streams. But UF/IFAS scientists have found that the oil extracted from Muscadine grape seeds produces a form of Vitamin E, which can help reduce fat.
In the human body, small wounds are easily treated by the body itself, requiring no further care. For bigger wounds to be healed, the body may need outside assistance. Concrete is like a living body, in that it can self-heal its own small wounds (cracks) as an intrinsic characteristic.
A new study led by researchers at Scripps Institution of Oceanography at UC San Diego indicates a steady population trend for blue whales and an upward population trend for fin whales in Southern California.
