Invasive lionfish likely safe to eat after all
Scientists from University of Hawaii have learned that recent fears of invasive lionfish causing fish poisoning may be unfounded. If so, current efforts to control lionfish by fishing derbies and targeted fisheries may remain the best way to control the invasion. And there's a simple way to know for sure whether a lionfish is toxic: test it after it's been cooked.

Study of bigeye tuna in Northwest Atlantic uses new tracking methods
This NOAA-funded research, which used a new approach to study one of the most important commercial tuna species in the Atlantic, provides the longest available fishery-independent record of bigeye tuna movements to date. Data should help researchers to further characterize habitat use and assess the need for more monitoring in high-catch areas.

Study of twins discovers gene mutation linked to short sleep duration
Researchers who studied 100 twin pairs have identified a gene mutation that may allow the carrier to function normally on less than six hours of sleep per night. The genetic variant also appears to provide greater resistance to the effects of sleep deprivation.

Stanford professor finds that wildfires and other burns play bigger role in climate change
Research demonstrates that it isn't just the CO2 from biomass burning that's the problem. Black carbon and brown carbon maximize the thermal impacts of such fires. They essentially allow biomass burning to cause much more global warming per unit weight than other human-associated carbon sources.

Certain Arctic lakes store more greenhouse gases than they release
New research, supported by the National Science Foundation, counters a widely-held scientific view that thawing permafrost uniformly accelerates atmospheric warming, indicating instead that certain Arctic lakes store more greenhouse gases than they emit into the atmosphere.

NIST corrosion lab tests suggest need for underground gas tank retrofits
A hidden hazard lurks beneath many of the roughly 156,000 gas stations across the United States.The hazard is corrosion in parts of underground gas storage tanks -- corrosion that could result in failures, leaks and contamination of groundwater, a source of drinking water. In recent years, field inspectors in nine states have reported many rapidly corroding gas storage tank components such as sump pumps.

Study finds benefits to burning Flint Hills prairie in fall and winter
A new study looks at 20 years of data concerning the consequences of burning Flint Hills prairie at different times of the year. It finds that burning outside of the current late spring time frame has no measurable negative consequences for the prairie, and in fact, may have multiple benefits.

Scientists find growing consensus: Political attitudes derive from body and mind
Neither conscious decision-making or parental upbringing fully explain why some people lean left and others lean right, researchers say. A mix of deep-seated psychology and physiological responses are at the core of political differences.

Breakthrough in understanding of important blood protein
New Danish research describes a previously unknown protein mechanism. This provides an exceptionally detailed understanding of how nature works, and it can also provide the ability to control nature -- in this case, it is about how coagulated blood can be dissolved, and this can lead to treatment of diseases carrying a risk of blood clots.

Hope for the overweight
The body has different types of adipose tissue that perform various metabolic tasks: white, beige and brown. For the first time, researchers at the Helmholtz Zentrum Muenchen and Harvard Medical School have successfully identified specific surface proteins that can help distinguish between the three types. This discovery makes it possible to develop new treatment options for adiposity. The work has been published in Science Translational Medicine.

A mathematical theory proposed by Alan Turing in 1952 can explain the formation of fingers
Researchers from the Centre for Genomic Regulation in Barcelona, show that BMP and WNT proteins are the so-called 'Turing molecules' for creating embryonic fingers. Findings explain why polydactyly -- the development of extra fingers or toes -- is relatively common in humans, affecting up to one in 500 births, and confirms a fundamental theory first proposed by the founding father of computer science, Alan Turing, back in 1952.

Innovative 'genotype first' approach uncovers protective factor for heart disease
Extensive sequencing of DNA from thousands of individuals in Finland has unearthed scores of mutations that destroy gene function and are found at unusually high frequencies. Among these are two mutations in a gene called LPA that may reduce a person's risk of heart disease. These findings are an exciting proof-of-concept for a new 'genotype first' approach to identifying rare genetic variants associated with, or protecting from, disease followed by extensive medical review of carriers.

New mapping approach lets scientists zoom in and out as the brain processes sound
Researchers at Johns Hopkins have mapped the sound-processing part of the mouse brain in a way that keeps both the proverbial forest and the trees in view. Their imaging technique allows zooming in and out on views of brain activity within mice, and it enabled the team to watch brain cells light up as mice 'called' to each other. The results represent a step toward better understanding how our own brains process language.

See-through organs and bodies will accelerate biomedical discoveries
The ability to see through organs and even the entire body has been a long-time dream of biologists. A new study has now made that dream a reality, revealing simple methods for making opaque organs, bodies, and human tissue biopsies transparent, while keeping the cellular structures and connections intact. The protocols could pave the way for a better understanding of brain-body interactions, more accurate clinical diagnoses and disease monitoring, and a new generation of therapies.

Mosaicism: Study clarifies parents as source of new disease mutations
Scientists have long speculated that mosaicism -- a biological phenomenon, in which cells within the same person have a different genetic makeup -- plays a bigger role in the transmission of rare disease mutations than is currently known. A study conducted by an international team of scientists led by Baylor College of Medicine sheds new light on the frequency of mosaicism in genomic disorders and its influence on recurrence risk.
