The geography of Antarctica's underside
Scientists were able to deploy ruggidized seismometers that could withstand intense cold in Antarctica only recently. A line of seismometers strung across the West Antarctic Rift Valley and the Marie Byrd Land have given geologists their first good look at the mantle beneath the ice and rocks, revealing areas of hot rock that might affect the behavior of the overlying ice sheet.

Researchers develop nanoscale probes for ssDNA sustainability under UV radiation
A team of researchers from Lehigh University, the University of Central Florida and the National Institute of Standards and Technology set out to understand the stability of DNA as a carrier of genetic information against potential damage by UV radiation. They have reported their findings in a paper recently accepted for publication in Nano Research.

Researchers resolve structure of a key component of bacterial decision-making
For bacteria that swim, determining whether to stay the course or head in a new direction is vital to survival. A new study offers atomic-level details of the molecular machinery that allows swimming bacteria to sense their environment and change direction when needed.

Seeing viruses in a new light
If researchers can understand how viruses assemble, they may be able to design drugs that prevent viruses from forming in the first place. Unfortunately, how exactly viruses self-assemble has long remained a mystery because it happens very quickly and at such small length-scales. Now, there is a system to track nanometer-sized viruses at sub-millisecond time scales. The method is the first step towards tracking individual proteins and genomic molecules at high speeds as they assemble to create a virus.

Climate change governs a crop pest, even when populations are far-flung
Research appearing today in Nature Climate Change shows how large-scale climatic changes drive a coordinated rise and fall of numbers of aphids across Great Britain, even when individual aphid populations in that nation are separated by great distance.

Sperm crane their neck to turn right
Spermatozoa need to crane their necks to turn right to counteract a left-turning drive caused by the rotation of their tails, new research has found. Led by Dr. Vasily Kantsler of the University of Warwick's Department of Physics, the researchers discovered that all sperm tails (flagella) rotate in a counter-clockwise motion as they beat to enable them to move through and against the motion of a fluid.

Stretchy hydrogel 'Band-Aid' senses, lights up, delivers medicine
MIT engineers have designed what may be the Band-Aid of the future: a sticky, stretchy, gel-like material that can incorporate temperature sensors, LED lights, and other electronics, as well as tiny, drug-delivering reservoirs and channels. The 'smart wound dressing' releases medicine in response to changes in skin temperature and can be designed to light up if, say, medicine is running low.

Higher levels of Fukushima cesium detected offshore
Scientists monitoring the spread of radiation in the ocean from the Fukushima nuclear accident report finding an increased number of contaminated sites off the US West Coast, along with the highest detection level to date, from a sample collected about 1,600 miles west of San Francisco. The level of cesium in the sample is 50 percent higher than other samples collected, but is still more than 500 times lower than US government safety limits.

Minutest absolute magnetic field measurement
Every measurement is potentially prone to systematic error. The more sensitive the measurement method, the more important it is to make sure it is also accurate. This is key for example in measuring magnetic fields in physics experiments. Now, an international team of physicists has developed an extremely high-precision method for the determination of magnetic fields. The findings by Hans-Christian Koch from the University of Fribourg, Switzerland, and colleagues are published in EPJ D.
