Meta-transmitarray offers unprecedented control of light on subwavelength scales
Trending at SXSW: Mind cloning, off-the-grid messaging
As a plane with a Grumpy Cat flag flew overhead, courtesy of Friskies, the Technorati flooded into panel discussions and happy hour spots at the annual tech festival South by Southwest in Austin, Texas, on ...
Hippo 'crosstalk' may be vital to tumor suppression
Think of a waterfall, and you might see why cell-signaling pathways are important to cancer research. As water cascades, it impacts everything downstream. And everything upstream affects the waterfall.
Complex nerve-cell signaling traced back to common ancestor of humans and sea anemones
New research shows that a burst of evolutionary innovation in the genes responsible for electrical communication among nerve cells in our brains occurred over 600 million years ago in a common ancestor of ...
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 ...
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 ...
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.
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.
First contracting human muscle grown in laboratory
In a laboratory first, Duke researchers have grown human skeletal muscle that contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals.
Precise and programmable biological circuits
A team led by ETH professor Yaakov Benenson has developed several new components for biological circuits. These components are key building blocks for constructing precisely functioning and programmable bio-computers.
Frogs without ears hear with their mouth
Gardiner's frogs from the Seychelles islands, one of the smallest frogs in the world, do not possess a middle ear with an eardrum yet can croak themselves, and hear other frogs. An international team of scientists ...
By blocking key signal, researchers maintain embryonic stem cells in vital, undifferentiated state
In a paper published in this week's Online Early Edition of the Proceedings of the National Academy of Sciences, researchers from the University of California, San Diego School of Medicine identify a key gene receptor and si ...
How cells communicate
During embryonal development of vertebrates, signaling molecules inform each cell at which position it is located. In this way, the cell can develop its special structure and function. For the first time ...
Movement in the womb sparks specific genes to build a healthy skeleton
(Phys.org) —Zoologists and bioengineers from Trinity College Dublin have identified over 1,000 genes whose responses change markedly when embryos are not able to move freely in the womb. The discovery will help scientists ...
