Cardiologist's 'living chip' changes science of disease monitoring

...the ability to detect changes. A change triggers a message to a wireless device to alert the patient early on about a problem. The patient can then contact their physician. For a patient with heart failure, for example, the biosensor could detect a change in blood protein levels at an early stage, promptin...

Most widely used organic pesticide requires help to kill

...ease in humans and other animals. "The take-home message is that we've shown that the mechanism of killing for Bacillus thuringiensis is facilitated by the normal gut community," says Nichole Broderick, a UW-Madison graduate student and the lead author of the PNAS study. "This is a mechanism that was not p...

P(acman) takes a bite out of deciphering Drosophila DNA

...too little. In other instances, it may disrupt the message from another gene. “You are really comparing apples and oranges when you do this,?said Bellen. The technique is also limited to small DNA chunks. “Koen set out to develop a new transgenesis system using the three techniques,?said Bellen. Th...

Biotech cotton provides same yield with fewer pesticides

...cts of transgenics," Carrière said. "The take-home message is that transgenic crops are very promising for reducing the impact of agriculture, but we need to study how they're integrated into the way we do agriculture. It depends on how the producers react to the technology." He added, "It's a problem tha...

Immune cell communication key to hunting viruses, Jefferson immunologists show

...ne, we have this very strong binding. An important message is that a single virus-MHC complex recognized in the context of self-MHC complexes is sufficient to activate a T-cell response, which is amazing," he says. "That's the power of killer cells. "We always suspected that recognition of other peptide M...

Ozone recovering, but unlikely to stabilize at pre-1980 levels, says study

...f the signaling cascade that relays brassinolide's message into a cell's nucleus, postdoctoral researcher and lead author of the study Grégory Vert, now at the Centre national de la recherche scientifique (CNRS) in Montpellier, France, said, "All the players are old acquaintances and we knew from genetic stu...

Salk scientists untangle steroid hormone signaling in plants

...f the signaling cascade that relays brassinolide's message into a cell's nucleus, postdoctoral researcher and lead author of the study Grégory Vert, now at the Centre national de la recherche scientifique (CNRS) in Montpellier, France, said, "All the players are old acquaintances and we knew from genetic stu...

Researchers discover how bacteria sense their environments

...signals to the brain, where many cells process the message to understand what we are smelling or tasting. But a bacterium is just a single cell, and it must use many different receptors to sense and interpret everything around it. Bacteria can sense in their environments changes in molecular concentrations...

Scientists discover new regulating mechanism in cells

...sed to remove non-essential information. Then, the message travels from the cell nucleus to another location,...toplasm. Last, other cell machinery translates the message and assembles the protein. The findings by Boris-Lawrie and her collaborators show that RHA can pl...

Einstein researchers take the pulse of a gene in living cells

...anscription, is crucial for translating the gene's message into a functional protein. Diseases such as cancer can result when genes turn on at the improper time or in the wrong part of the body. Researchers customarily use microarrays (also known as "gene chips") to assess gene expression in tumors and oth...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

... panic and dangerous behavior." The researchers' message isn't just that psilocybin can produce mystical experiences. "I had a healthy skepticism going into this," says Griffiths, "and that finding alone was a surprise." But, as important, he says, "is that, under very defined conditions, with careful prep...

Some people would give life or limb not to be fat

...crifices to avoid being obese. It drives home the message that weight bias is powerful and pervasive," said Marlene Schwartz, associate director of the Rudd Center and lead author of the study in Obesity, which was issued this month. In addition to these comments, the study assessed implicit and explicit,...

Bird brains shrink from exposure to contaminants

...e at risk of neurological damage. "The take-home message is that people need to be more cognizant of their use of pesticides and herbicides," said Iwaniuk. "People need to be careful about using chemicals in their homes or farms. Who knows the effects these will have down the road." For more information,...

Gold nanoparticles could improve antisense cancer drugs

...r RNA by using 'antisense DNA,' which prevents the message from ever becoming a protein." Once inside cells, the DNA-modified nanoparticles act as messenger RNA "sponges" that bind to their targets and prevent them from being converted into proteins. In their experiments the researchers targeted mRNA sequ...

Nicotine exposure during development leads to hearing problems

...nt." Chemicals known as neurotransmitters act as message carriers between cells and bind with receptors on the cells' surfaces, much like a key fits into the lock. If the receptors are damaged, they can no longer bind properly with the neurotransmitter. Nicotine shares a receptor with the neurotransmitter ...

Research reveals inner workings of immune system 'thermostat'

...ed fashion." Yap said the findings should send a message to drug companies designing and testing tyk2-inhibiting medicines for arthritis and other autoimmune diseases. Block tyk2 function, Yap said, and patients will be more prone to infection ?and their arthritis may not be relieved. "There could be a dow...

Global study shows all tobacco bad for the heart

...eople around the world should pay attention to the message that it's never too late to quit. This is an important study documenting the powerful and persistent dangers of tobacco use worldwide," said Dr. Peter Liu, scientific director for CIHR's Institute of Circulatory and Respiratory Health (ICRH). "Cana...

Many cleaners, air fresheners may pose health risks when used indoors

...s and activities during the year. The take-home message from these studies, according to Nazaroff, is that everyone ?but especially cleaning professionals ?should be cautious about overuse of products with high levels of ethylene-based glycol ethers and terpenes. Rooms should be ventilated during and afte...

Mosquito spray increases toxicity of pyrethroids in creek, study finds

... of Environmental Science & Technology, send a message to environmental regulators to reassess how they evaluate a product's toxicity, said Donald Weston, UC Berkeley adjunct professor of integrative biology and lead author of the study. "This interaction of compounds is a whole new issue when doing pest...

Study shows hope for ridding lakes of clawed invader

... is helping oversee the experiment. "One important message is that trapping alone will not do it. There's a synergistic effect with the fish playing an important role." Smallmouth bass and rock bass, says Vander Zanden, are the primary predators of juvenile crayfish, and to some degree sunfish - bluegills ...
