Soybean science blooms with supercomputers
Soybean Knowledge Base (SoyKB) project finds and shares comprehensive genetic and genomic soybean data through support of NSF-sponsored XSEDE high performance computing. SoyKB helps scientists improve soybean traits. XSEDE Stampede supercomputer 370,000 core hour allocation used in resequencing of over 1,000 soybean germplasm lines. XSEDE ECSS established Pegasus workflow that optimized SoyKB for supercomputers. SoyKB migrated workflow to XSEDE Wrangler data intensive supercomputer. Scientific cloud environment Jetstream of XSEDE broadened user base.

Fewer low clouds in the tropics
With the help of satellite data, ETH scientists have shown that low-level cloud cover in the tropics thins out as the earth warms. Since this cloud cover has a cooling effect on the climate, the two-degree warming target may therefore be reached earlier than many models have predicted.

Female fish can favor sperm from preferred males despite external fertilization
Biologists studying a small, colorful fish in the Mediterranean Sea have discovered a new way in which a female can choose the best father for her offspring. During spawning of the ocellated wrasse, ovarian fluid released with eggs favors sperm from the nest-tending males preferred by the females, limiting fertilization by 'sneaker' males.

Scientists on the prowl for 'the ultimate Pokémon'
Researchers are on a real-life search for what one calls 'the ultimate Pokémon': Zenkerella, an elusive scaly-tailed squirrel that has never been spotted alive by scientists. However, biologists recently found three newly dead specimens that hint at how the 'living fossil' has evolved over the past 49 million years. Based on DNA results, the researchers determined that Zenkerella is a very distant cousin of two scaly-tailed squirrels that glide from tree to tree.

Unraveling knotty chemical structures enables rapid screening of anti-cancer compounds
It isn't often that a graduate student makes a spectacular technical leap in his field, or invents a process that can have a significant impact on a real-world problem. Di Liu did both. Liu, a chemistry graduate student at the University of Chicago, devised an ingenious way to make tiny knotted and interlocked chemical structures that have been impossible for chemists to fabricate until now.

CU Boulder study: Mate choices of barn swallows tied to diverging appearances
If you are a male barn swallow in the United States or the Mediterranean with dark red breast feathers, you're apt to wow potential mates. But if you have long outer tail feathers in the United States, or short ones in the Mediterranean, the females may not be so impressed.

Directly reprogramming a cell's identity with gene editing
Researchers have used a gene editing tool called CRISPR to turn cells isolated from mouse connective tissue directly into neuronal cells. Results indicate that the newly converted neuronal cells show a more complete conversion than previous techniques, which persists after the treatment has ended. These cells could be used for modeling neurological disorders, discovering new therapeutics, developing personalized medicines and, perhaps in the future, implementing cell therapy.

Disrupting mitochondrial function could improve treatment of fungal infections
By identifying new compounds that selectively block mitochondrial respiration in pathogenic fungi, Whitehead Institute scientists have identified a potential antifungal mechanism that could enable combination therapy with fluconazole, one of today's most commonly prescribed fungal infection treatments. Severe, invasive fungal infections have a mortality rate of 30-50 percent and cause an estimated 1.5 million deaths worldwide annually. Current antifungal therapies are hampered by the increasingly frequent emergence of drug resistance and negative interactions that often preclude combination use.

Stress bites! USF researchers study mosquito/bird interactions
When researchers from USF and colleagues investigated how the stress hormone, corticosterone, affects how birds cope with West Nile virus, they found that birds with higher levels of stress hormone were twice as likely to be bitten by mosquitoes that transmit the virus. Their studies have implications for the transmission of other viruses such Eastern Equine Encephalitis, and perhaps even Zika, both known to be carried by the kind of mosquitoes used in this study.

Slowly pulling proteins apart reveals unexpected path to stability
Researchers have taken a different approach to studying the conformations of larger proteins. By slowly pulling apart a protein called Protein S, they discovered a previously unknown stable conformation made possible by balancing charges between two domains. The results show some of the field's long-held ideas need to be revised.
