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 ...
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.
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 ...
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. ...
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, ...
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 ...
