Meta-transmitarray offers unprecedented control of light on subwavelength scales
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 ...
Protein structure reveals how cells regulate their skeletons
Insight into the regulation of cell skeleton structure has come from a study conducted by A*STAR researchers. The work, which solved a protein structure that has eluded scientists for 20 years, should lead ...
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.
Biologist advances cancer research with new data analysis techniques
Patience and persistence are beginning to pay off for University of Montana Professor Mark Grimes, whose research about the behavior of cell proteins in childhood cancer recently was published by the Public Li ...
The mechanics of life
An interdisciplinary research team formed by Otger Campàs, assistant professor in the Department of Mechanical Engineering at the University of California, Santa Barbara (UCSB), and colleague Jérome Gros, ...
New tech keeps your smart phone charged for 30 percent longer
New technology developed at The Ohio State University makes cell phone batteries last up to 30 percent longer on a single charge.
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.
How to reset a diseased cell
In proof-of-concept experiments, researchers at University of California, San Diego School of Medicine demonstrate the ability to tune medically relevant cell behaviors by manipulating a key hub in cell communication networks. ...
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 ...
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.
