Researchers find glass eels use internal compass to find their way home
Scientists are closer to unraveling the long-standing mystery of how tiny glass eel larvae, which begin their lives as hatchlings in the Sargasso Sea, know when and where to 'hop off' the Gulf Stream toward European coastlines to live out their adult lives in coastal estuaries.

Rattling DNA hustles transcribers to targets
'DNA is a bully.' That's how researcher Jeffrey Skolnick sums up the dominant power of DNA motion among the forces acting upon transcription factors as they move through DNA's winding thickets to their target sites. He and Edmond Chow have programmed a very large, unique simulation that tests and corroborates the hypothesis.

Promiscuous salamander found to use genes from 3 partners equally
A study shows that a unique all-female lineage of salamander equally balances genes from the males of three other salamander species. The findings highlight the bizarre ways some animals reproduce in order to preserve their species. The results were published in the journal Genome Biology and Evolution.

UH geochemist searches for answers on the sea floor
The sea floor may look barren, but Qi Fu, an experimental geochemist at the University of Houston, says there are places where it is teeming with life. Fu has received a five-year, $516,575 CAREER Award from the National Science Foundation to pursue the study of how organic compounds are formed in hydrothermal environments on the sea floor.

Uncovering the biology of a painful and disfiguring pediatric disease
The study reveals a major physiological function for the CMG2 gene and demonstrates its interaction with collagen VI. This interaction explains how major Hyaline Fibromatosis Syndrome symptoms arise when mutation of the CMG2 gene disrupts the ability of the CMG2 protein to control the levels of collagen VI, which then over-accumulates and produces the painful and disfiguring symptoms of the disease.

Detailed new genome for maize shows the plant has deep resources for continued adaptation
A much more detailed reference genome for maize is published in Nature today. The sequence of DNA letters in the plant's 10 chromosomes reveals how how incredibly flexible it is, a characteristic that directly follows from the way its genome is organized. This flexibility not only helps explain why maize has been so successful since its adaptation by agriculturalists thousands of years ago, but also bodes well for its ability to grow in new places as the earth's climate changes.

Microbes give meerkat gangs their signature scents
Body odor. To some it's an embarrassing nuisance. But to meerkats, it's a calling card. Meerkats produce a pungent 'paste' that they use to mark their turf. With one whiff they can tell if a scent belongs to a relative, a rival or a potential mate. But the chemical signals in this stinky graffiti don't come from the meerkats themselves; they're made by odor-producing bacteria that thrive in the meerkats' gooey secretions, researchers find.

Peatlands, already dwindling, could face further losses
Tropical peatlands have been disappearing fast due to clear-cutting and drainage projects. Now, new research from MIT shows peatlands face another threat, as climate change alters rainfall patterns, potentially destroying much of what remains and turning these carbon sinks into net carbon sources.

Lianas stifle tree fruit and seed production in tropical forests
Vines compete intensely with trees. Their numbers are on the rise in many tropical forests around the world. A new study at the Smithsonian Tropical Research Institute in Panama shows that lianas prevent canopy trees from producing fruit, with potentially far-reaching consequences for rainforest animals.

New way to weigh a white dwarf: Use Hubble Space Telescope
For the first time, astronomers have used a novel method to determine the mass of a type of star known as a 'white dwarf' -- the shrunken corpse of a dead star that used to be like our sun. The achievement, made with the Hubble Space Telescope, is described as a wonderful confirmation of theoretical predictions, and a beautiful reprise of the Einstein solar eclipse observations of a century ago.

Space-traveling flatworms help scientists enhance understanding of regenerative health
Flatworms that spent five weeks aboard the International Space Station are helping researchers led by Tufts University scientists to study how an absence of normal gravity and geomagnetic fields can have anatomical, behavioral, and bacteriological consequences, according to a paper to be published June 13 in Regeneration. The research has implications for human and animal space travelers and for regenerative and bioengineering science.

Lost ecosystem found buried in mud of southern California coastal waters
Paleontologists investigating the sea bed off California have discovered a lost ecosystem that for thousands of years had nurtured communities of scallops and shelled marine organisms called brachiopods. They had died off by the early 20th century, replaced by the mud-dwellling burrowing clams that inhabit this seabed today. Paleontologists Adam Tomašových of the Slovak Academy of Sciences and Susan Kidwell of the University of Chicago examine the lost ecosystem in a new study.

Research targets PFOA threat to drinking water
A highly toxic water pollutant, known as perfluorooctanoic acid (PFOA), last year caused a number of US communities to close their drinking water supplies. PFOA contamination also is a pervasive problem worldwide. A Northwestern University-led research team now reports an inexpensive and renewable material that rapidly removes PFOA from water. The novel treatment effectively eliminates the micropollutant to below 10 parts per trillion, far below US Environmental Protection Agency and all state health advisory limits.

Bee buzzes could help determine how to save their decreasing population
Widespread and effective monitoring of bees could lead to better management of populations; however, tracking bees is tricky and costly. Now, a research team led by the University of Missouri has developed an inexpensive acoustic listening system using data from small microphones in the field to monitor bees in flight. The study, published today in PLOS ONE, shows how farmers could use the technology to monitor pollination and increase food production.
