Charred micro-bunny sculpture shows promise of new material for 3-D shaping
Researchers in Japan used state-of-the-art micro-sculpting techniques on a new type of resin that can be molded into complex, highly conductive 3-D structures (in this case the famous "Stanford bunny") with ...
Parasitic wasps use calcium pump to block fruit fly immunity
Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses.
Research on cilia heats up: Implications for hearing, vision loss and kidney disease
Experiments at Johns Hopkins have unearthed clues about which protein signaling molecules are allowed into hollow, hair-like "antennae," called cilia, that alert cells to critical changes in their environments.
Fluorescent indicator could help scientists identify useful drugs that modulate process of cell death
Apoptosis is a programmed death mechanism that eliminates unwanted or injured cells from the body. Defects in apoptotic regulation can lead to serious physiological problems such as tissue damage or uncontrolled ...
Chaos proves superior to order
An international team of physicists, including researchers from the Universities of York and St. Andrews, has demonstrated that chaos can beat order - at least as far as light storage is concerned.
Discovery alters understanding of long-distance intercellular communication
(Phys.org) —In a finding likely to fundamentally reshape biologists' understanding of how vertebrate cells communicate, researchers at the Stanford University School of Medicine and the UC-San Francisco ...
Neural activity in bats measured in-flight
Animals navigate and orient themselves to survive – to find food and shelter or avoid predators, for example. Research conducted by Dr. Nachum Ulanovsky and research student Michael Yartsev of the Weizmann ...
Previously unpublished paper by Francis Crick and Jeffries Wyman, "A footnote on allostery"
It is rare that an unpublished piece of research or theory remains significant after half a century. It is also a wonderful example of the boundless curiosity of the late Francis Crick. A previously unpublished work by Francis ...
Startup links families with their independent seniors
A new way for families to stay close to independent elders that blends modern technology with old fashioned parcel post debuted on crowd-funding website Kickstarter Tuesday.
Small in size, big on power: New microbatteries the most powerful yet
(Phys.org) —Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered ...
3-D printer builds synthetic tissues
A custom-built programmable 3D printer can create materials with several of the properties of living tissues, Oxford University scientists have demonstrated.
Electrical signals dictate optical properties
Researchers at the University of Southampton's Optoelectronics Research Centre (ORC) have created an artificial material, a metamaterial, with optical properties that can be controlled by electric signals.
European collaboration sheds light on plasmonic enhancement of solar cell efficiency
Imec, together with its project partners, have cooperated within an EU 7th framework program (FP7) project PRIMA to improve both the efficiency and cost of solar cells. In particular, they have worked on ...
Scientists show that graphene is highly efficient in converting light to electricity
Bottles, packaging, furniture, car parts... all made of plastic. Today we find it difficult to imagine our lives without this key material that revolutionized technology over the last century. There is wide-spread optimism ...
