Plants respond similarly to signals from friends, enemies

...ctors." After rhizobia perceive plant signals and send back Nod factors, the plant's root hairs curl around the good bacteria. The rhizobia then migrate into the root and form special structures called nodules, where they turn atmospheric nitrogen into usable nitrogen for the plant and, in return, take s...

Spider Venom Could Yield Eco-Friendly Insecticides

...b spider -- toxins that either paralyze insects or send their nervous systems into overdrive. King's NSF-funded research has provided the first detailed descriptions of the regions of the toxins that are essential for interaction with insect ion channels. (Ion channels allow the movement of ions -- small ...

First real-time view of developing neurons reveals surprises, say Stanford researchers

...shing the final wiring of the brain. Young neurons send out branches in all directions in the hopes that some branches will connect to other neurons and form synapses that transfer information. As the neuron matures, some of these branches form stable synapses while others recede. This trial-and-error pro...

FDA Warns Consumers Not to Use Home-Use Diagnostic Kits Marketed by Globus Media

No home-use test kits intended for diagnosing syphilis and dengue fever are approved for sale in the U.S. The FDA has issued an import alert which alerts FDA field personnel to the possible importation of the Globus Medi...

Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

...layering of gallium aluminum arsenide combinations send up numerous tiny beams from a small cross-sectional generating area. These beams are reinforced or thwarted by the position and density of the mitochondria. "The pictures we get from normal and cancer cells are very different," says Gourley. "Mitoch...

VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain

...of molecular insulation that allows nerve cells to send impulses to one another more effectively. Such pathways showed different responses to alcohol in one mouse strain versus the other. As a result, Miles and his colleagues were able to formulate new hypotheses about how the brains of the mouse strains ...

Mayo Clinic Researchers Create 'Obedient Virus'; First Step To Use Measles Virus Against Cancer

...ake our pick as to what new receptor we target and send the virus after it." How They Did It Using bioengineering techniques, the team reprogrammed the measles virus to seek a cancer cell to bind to instead of its natural binding partner. Then they invented a "molecular tag" that they attached to struct...

Programmable cells: Engineer turns bacteria into living computers

...egrated package where the cells have an ability to send messages and other cells have the ability to act on these messages," said Weiss. The creation of patterns, such as the bull's-eye effect, is a key step in one of Weiss' eventual goals, which is to have the cells secrete materials that build physical...

Computational Method Speeds Mapping of Cell Signaling Networks

...s prompt activated T-cells to multiply rapidly and send out molecular "distress signals" that attract other immune system molecules to battle the infection. Components in the pathway are chemically altered during the signaling. Such alterations occur only at points of active signaling in the network. The...

Brain-mapping technique aids understanding of sleep, wakefulness

...leep. Mapping the neurons to which orexin neurons send signals has been relatively easy, Dr. Yanagisawa said, but determining which neurons send signals to orexin neurons has been a challenge. A brain-mapping technique developed recently by Fren...

Potential Drug Target For Treating Cocaine Abuse Found

Researchers have long searched for "a molecule that would block cocaine's effects on the transporter without inhibiting the transporter by itself," notes Eric Nestler, chair of psychiatry at the Un...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...elephants actually have the physical capability to send and receive low-frequency vibrations. To do that, they had to convince skeptical geophysicists, like Hart's brother, Byron Aranson. "It was a unique collaboration," Hart says. "We started with the physics of it, then moved to behavior and how the an...
