Successful prediction of multi-year US droughts and wildfire risk
A new study shows that difference in water temperature between the Pacific and the Atlantic oceans together with global warming impact the risk of drought and wildfire in southwestern North America. A new model proves capable of much longer-term forecasts of mega-drought and active wildfire seasons than those currently available to people in agriculture, water management and forestry.

A closer look at osteoporosis medication's mechanisms may improve outcomes
Osteoporosis is the primary cause of bone fractures in the elderly, reflecting an imbalance between osteoclasts, bone-degrading cells, and osteoblasts, bone-building cells. Teriparatide is the only FDA-approved treatment for osteoporosis that increases osteoblast activity and lifespan. This week in the JCI, Henry Kronenberg and colleagues at Massachusetts General Hospital report that teriperatide treatment also stimulates the formation of new osteoblasts. However, their findings also show that unexpected adverse effects can develop after treatment stops.

Study finds parallels between unresponsive honey bees, human autism
Honey bees that consistently fail to respond to obvious social cues -- the presence of an intruder or of a queen larva, for example -- share something fundamental with autistic humans, researchers report in a new study. Genes most closely associated with autism spectrum disorders in humans are regulated differently in unresponsive honey bees than in their more responsive nest mates, the study found.

Study highlights underlying mechanisms of fractures associated with osteoporosis drug
There is no disputing that the use of bisphosphonates -- with brand names such as Fosamax, Boniva and Reclast -- is proven to combat bone loss and fragility fractures in millions of osteoporosis patients for whom a fracture could be debilitating, even life-threatening.

Stampede2 storms out of the corral in support of US scientists
Stampede2 is the newest strategic resource for the US academic community, enabling thousands of researchers to answer questions that cannot be addressed through theory or experimentation alone and that require high-performance computing power. Currently the 12th most powerful supercomputer in the world, Stampede2 is fastest at any university in the US. When fully deployed later this summer, it will have a peak performance of 18 petaflops, or 18 quadrillion mathematical operations per second.

A study by MIT researchers shows that collections of ultracold molecules can retain the information stored in them for hundreds of times longer than previously achieved in these materials. These clusters might thus serve as 'qubits,' the basic building blocks of quantum computers.

'Dark ecology project' will use past weather radar data to trace bird migrations
Every spring and fall, billions of birds migrate across the United States, largely unseen under the cover of darkness. Now a team of researchers led by computer scientist Daniel Sheldon at the University of Massachusetts Amherst plan to develop new analytic methods with data collected over the past 20 years -- more than 200 million archived radar scans from the national weather radar network -- to provide powerful new tools for tracking migration.

Sticky when wet: Strong adhesive for wound healing
A team of researchers from the Wyss Institute at Harvard University has created a super-strong 'tough adhesive' that is non-toxic and binds to biological tissues with a strength comparable to the body's own resilient cartilage, even when they're wet. Inspired by the glue produced by a slug, the double-layered hydrogel material demonstrates both high adhesion strength and strain dissipation, making it useful in a variety of medical applications.

Shedding light deeper into the human brain
The inner workings of the human brain have always been a subject of great interest. Unfortunately, it is fairly difficult to view brain structures or intricate tissues due to the fact that the skull is not transparent by design. The reality is that light scattering is the major obstacle for deep penetration into tissue.
