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 ...
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.
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 ...
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.
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.
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 ...
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.
Cells can use dynamic patterns to pluck signals from noise
Scientists have discovered a general principle for how cells could accurately transmit chemical signals despite high levels of noise in the system, they report in Science this week.
Signaling molecule crucial to stem cell reprogramming
While investigating a rare genetic disorder, researchers at the University of California, San Diego School of Medicine have discovered that a ubiquitous signaling molecule is crucial to cellular reprogramming, a finding with ...
A novel method for identifying the body's 'noisiest' networks
(Phys.org) —A team of scientists led by Yale University systems biologist and biomedical engineer Andre Levchenko has developed a novel method for mapping the biochemical variability, or "noise," in how ...
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.
Tracing water channels in cell surface receptors
G protein-coupled receptors (GPCRs) are the largest class of cell surface receptors in our cells, involved in signal transmission across the cell membrane. One of the biggest questions is how a signal recognized at the extracellular ...
