New internet routing method allows users to avoid sending data through undesired countries
University of Maryland computer scientists have developed a method for providing concrete proof to Internet users that their information did not cross through specified, undesired geographic areas. Called Alibi Routing, the system is immediately deployable and does not require knowledge of -- or modifications to -- the Internet's routing hardware or policies. The method will be presented on Aug. 20 at the Association for Computing Machinery Special Interest Group on Data Communication conference in London.

Cell phones help track of flu on campus
Personal health and lifestyle data captured through smartphone apps can help identify college students at risk of catching the flu. With help from a mobile app that monitors who students interact with and when, North Carolina researchers have developed a model that enables them to predict the spread of influenza infections. Unlike most models, their approach gives a personalized daily forecast for each patient.

Examining the fate of Fukushima contaminants
An international research team reports results of a three-year study of sediment samples collected offshore from the Fukushima Daiichi Nuclear Power Plant in a new paper published Aug. 18, 2015, in the American Chemical Society's journal, Environmental Science and Technology. The research aids in understanding what happens to Fukushima contaminants after they are buried on the seafloor off coastal Japan.

Global warming lethal to baby lizards: Nests become heat traps
The expected impact of climate change on North American lizards is much worse than first thought. A team of biologists led by Arizona State University investigators has discovered that lizard embryos die when subjected to a temperature of 110 degrees Fahrenheit even for a few minutes. They also discovered a bias in previous studies, which ignored early life stages such as embryos. Embryonic lizards are immobile and cannot cool off when surrounding soil becomes hot.

Targeting HIV in semen to shut down AIDS
There may be two new ways to fight AIDS -- using a heat shock protein or a small molecule -- to attack fibrils in semen associated with HIV during the initial phases of infection. HIV is most commonly transmitted in semen, which contains amyloid fibrils. These can increase the transmission of HIV by helping the it attach to the membrane surrounding human cells.

Fossil study: Dogs evolved with climate change
A cooling, drying climate over the last 40 million years turned North America from a warm and wooded place into the drier, open plains we know today. A new study shows how dogs evolved in response to those changes, demonstrating that predators are sensitive to climate change because it alters the hunting opportunities in their habitat.

Controlling the uncontrollable
Soft machines and robots are capable of moving, jumping and gripping objects thanks to soft, inflatable segments called fluidic actuators. These actuators require large amounts of air or water to change shape, making the machines slow, bulky and difficult to untether but a team of researchers at the Harvard John A. Paulson School of Engineering and Applied Science have engineered a new, soft actuator that harnesses the power of instability to trigger instantaneous movement.

Dancing droplets launch themselves from thin fibers
Researchers have observed droplets spontaneously fling themselves from thin fibers. The phenomenon occurs so long as the fibers are small enough relative to the coalescing droplets and moderately hydrophobic, and has applications ranging from water purification to oil refining.

Carnegie Mellon BrainHub scientists visualize critical part of basal ganglia pathways
Certain diseases, like Parkinson's and Huntingdon's disease, are associated with damage to the pathways between the brain's basal ganglia regions. For the first time, Carnegie Mellon University BrainHub scientists have used a non-invasive brain-imaging tool to detect the pathways that connect the parts of the basal ganglia.

1,800 years of global ocean cooling halted by global warming
Prior to the advent of human-caused global warming in the 19th century, the surface layer of Earth's oceans had undergone 1,800 years of a steady cooling trend, according to a new study in the Aug. 17, 2015 issue of the journal Nature Geoscience. The results also indicate that the coolest temperatures occurred during the Little Ice Age -- a period that spanned the 16th through 18th centuries and was known for cooler average temperatures over land.

Frequent volcanic eruptions likely cause of long-term ocean cooling
An international team of researchers found an 1800 year-long cooling trend in the surface layer of the Earth's oceans, and that volcanic eruptions were the likely cause of the cooling from 801 to 1800 AD. The coolest temperatures were during the Little Ice Age -- that was before man-made global warming erased the cooling trend in the 1800s.

Stanford engineers develop a wireless, implantable device to stimulate nerves in mice
A blue glowing device the size of a peppercorn can activate neurons of the brain, spinal cord or limbs in mice and is powered wirelessly using the mouse's own body to transfer energy. Developed by a Stanford Bio-X team, the device is the first to deliver optogenetic nerve stimulation in a fully implantable format.

Look at me! Forest-dwelling anoles 'glow' to attract attention
See and be seen. In the elaborate game of seeking and attracting a mate, male anole lizards have a special trick -- they grab attention by perching on a tree limb, bobbing their heads up and down, and extending a colorful throat fan, called a dewlap. The dramatic 'glowing' effect, according to a new study published in Functional Ecology, increases the efficacy of the male lizard's visual signal, making them stand out better to females.

Corrected protein structure reveals drug targets for cancer, neurodegenerative diseases
Protein Kinase C is a family of enzymes that controls the activity of other proteins in a cell by attaching chemical tags. That simple act helps determine cell survival or death. When it goes awry, a number of diseases may result. In a study, researchers at University of California, San Diego School of Medicine reveal a more accurate structure of PKC, providing new targets for fine-tuning the enzyme's activity as needed to improve human health.
