Balance, gait negatively impacted after chemotherapy treatment
A single chemotherapy treatment can result in a significant negative impact on walking gait and balance, putting patients at an increasing risk for falls, according to a new study involving breast cancer patients conducted by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James).

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.

New technique enables 3-D printing with paste of silicone particles in water
Using the principles behind the formation of sandcastles from wet sand, North Carolina State University researchers have achieved 3-D printing of flexible and porous silicone rubber structures through a new technique that combines water with solid and liquid forms of silicone into a pasty ink that can be fed through a 3-D printer. The finding could have biomedical applications and uses in soft robotics.

Mining cancer data for treatment clues
Genomics -- the branch of molecular biology concerned with the structure, function, evolution, and mapping of genomes -- has proved successful in uncovering the complex nature of cancer. Researchers have used supercomputers at the Texas Advanced Computing Center to gain insights into the relationship between DNA sequences that fold into secondary structures and chromosomal rearrangements; identify cancer subtypes that respond differently to treatments; and run biomedical analyses via the web.

'Immunoswitch' particles may be key to more-effective cancer immunotherapy
Scientists at Johns Hopkins have created a nanoparticle that carries two different antibodies capable of simultaneously switching off cancer cells' defensive properties while switching on a robust anticancer immune response in mice. Experiments with the tiny, double-duty 'immunoswitch' found it able to dramatically slow the growth of mouse melanoma and colon cancer and even eradicate tumors in test animals, the researchers report.

Oyster shells inspire new method to make superstrong, flexible polymers
Columbia Engineers developed a method inspired by the nacre of oyster shells, a composite material with extraordinary mechanical properties, including great strength and resilience. By changing the crystallization speed of a polymer well-mixed with nanoparticles, the team controlled how the nanoparticles self-assemble into structures at three different length scales. This multiscale ordering makes the base material almost an order of magnitude stiffer while still retaining the desired deformability and lightweight behavior of the polymeric materials.

A newly discovered Jupiter-like world is so hot that even its nights are like the flame of a welding torch. Planet KELT-9b is hotter than most stars. With a day-side temperature of more than 7,800 degrees Fahrenheit (4,600 Kelvin), it is only about 2,000 degrees Fahrenheit (1,200 Kelvin) cooler than our own sun.
