Unprecedented water level rise in Somalia

... Somaliland. The floods washed away one of the two bridges in the south-western part of the city and damaged huts and houses on the banks of the river as well as electric power lines. The destruction of the bridge limits the accessibility and mobility of the population around the city, affecting daily activi...

Beetle-inspired switch uses water for bonding

...s arrangements, Steen said. "This new technology bridges the gap between scales as large as our hands and nanoscales," said Steen. "We need devices that allow us to communicate between the two scales." Co-authors include Michael Vogel, a postdoctoral researcher in Cornell's Department of Chemical and Bi...

Cultural norms not unique to human societies

...n and uses a two-action methodology. This approach bridges the gap between two conventional research methods: population-level observations on wild apes and one-to-one social learning experiments. In the study, researchers introduced a naturalistic foraging task into three groups (two experimental and one c...

'Underground' tunnels discovered as means for communication between immune system cells

.... While gap junctions - interconnecting molecular bridges that conjoin tightly packed cells - are known to generate calcium signals and transport other molecules between cells, the researchers say the tunneling nanotubules are something quite different. "This is clearly a third form of intercellular commun...

New maps reveal true extent of human footprint on Earth

...l truly be a brave new experiment that effectively bridges science, decision-making and real-world environmental practice - collectively envisioning a new way to live sustainably." ...

Secrets of the sea yield stronger artificial bone

...r substance fills the space between them. And some bridges form between the layers, which are believed to increase fracture resistance. "These characteristics contribute to the scaffolding's mechanical toughness. Cracks don't propagate as easily and more energy is needed to break the material," says Tomsia....

Spinal cord bridge bypasses injury to restore mobility

...tion was at work in restoring movement, the neural bridges were severed and the rats lost all movement gained from the combination of treatments. This provides the most conclusive evidence to date that severed nerve fibers in the spinal cord can, in fact, regenerate for long distances and establish proper fu...

Two central mysteries in genome inheritance solved at UCSD

...at UCSD, identified a complex of two proteins that bridges chromosomes and spindle microtubules and is required to detect attachment errors. This complex controls activation of a protein kinase called Aurora. "A major question becomes, how are bad attachments detected"" said Desai. "Our results suggest ...

T-ray breakthrough could make detecting disease far easier

...cy is around one thousand billion cycles a second, bridges the gap between the microwave and infrared parts of the electromagnetic spectrum. Materials interact with radiation at T-ray frequencies in different ways than with radiation in other parts of the spectrum, making T-rays potentially important in ...

Progress toward an antitumor vaccine

...lled fashion. The largely nonimmunogenic thioether bridges could clear the way for the development of vaccines for immunization against tumor cells.”...

Caribbean frogs started with a single, ancient voyage on a raft from South America

...iola, and Puerto Rico had walked there across land bridges that existed when those islands were connected in a geologic arc about 70-to-80-million years ago. A second major theory proposed that they arrived, instead, by rafting across the Caribbean Sea after the giant asteroid impact near Cuba 65-million ye...
