Biology / Biochemistry News From Medical News Today
The film "Avatar" isn't the only 3-D blockbuster making a splash this winter. A team of Houston scientists this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testing costs. The research is reported in Nature Nanotechnology...
Biology / Biochemistry News From Medical News Today
US researchers have developed a new powerful microscopy technique and used it to show proteins killing bacteria in real time, thus revealing the deadly workings of antimicrobial peptides (AMPs), naturally occurring proteins that scientists are pursuing as a new approach to treating bacterial infections...
Biology / Biochemistry News From Medical News Today
In a new study published in Biological Psychiatry, by Elsevier, researchers have related the findings that are emerging from PET-PIB imaging to changes in the function of brain circuits. The emergence of multiple new brain imaging technologies and the combined application of these new approaches is helping to create new insights into aging and Alzheimer's disease...
Biology / Biochemistry News From Medical News Today
New research led by scientists at the University of Essex has given an insight into how the body finds damage in the DNA code to repair it. From rays of sunlight to harmful tobacco smoke, our bodies are bombarded every single day by a range of environmental toxins which damage our DNA...

A potent new inhibitor of HIV, derived from bananas, may open the door to new treatments to prevent sexual transmission of HIV, according to a University of Michigan Medical School study published this week. Scientists have an emerging interest in lectins, naturally occurring chemicals in plants, because of their ability to halt the chain of reaction that leads to a variety of infections...

Scientists headed by ICREA researcher Marco Milan, at the Institute for Research in Biomedicine (IRB Barcelona), reveal a surprising new function of Notch protein that contrasts with the one known to date. Found in the cell membrane, this protein activates a signalling pathway that regulates the expression of genes that make the cell divide, grow, migrate, specialise or die...
Biology / Biochemistry News From Medical News Today
Researchers at the University of Maryland Marlene and Stewart Greenebaum Cancer Center have discovered that "microtentacles," or extensions of the plasma membrane of breast cancer cells, appear to play a key role in how cancers spread to distant locations in the body...
Biology / Biochemistry News From Medical News Today
UCSF scientists have discovered how a mutated gene known as Kras is able to hijack mouse cells damaged by acute pancreatitis, putting them on the path to becoming pancreatic cancer cells. The finding, they say, suggests one way in which the mutated gene - found in nearly all cases of the most common and lethal form of pancreatic cancer - exacts its toll in humans...
Biology / Biochemistry News From Medical News Today
In a lecture he delivered in 1906, the German physician Paul Ehrlich coined the term Zuberkugel, or "magic bullet," as shorthand for a highly targeted medical treatment. Magic bullets, also called silver bullets, because of the folkloric belief that only silver bullets can kill supernatural creatures, remain the goal of drug development efforts today...

New findings that shed light on how genetic damage to muscle cell proteins can lead to the development of the rare muscle-wasting disease, nemaline myopathy, are reported in the Biochemical Journal...
Biology / Biochemistry News From Medical News Today
Van Andel Research Institute (VARI) researchers have developed a new method to better study the cells that line and protect the prostate in relation to the development of cancer. Using the model, they found that normal cells and cancer cells depend on different factors to survive, which could aid in discovering how to target cancer cells without affecting normal cells when developing treatments...
Biology / Biochemistry News From Medical News Today
A research team led by the University of Colorado at Boulder has discovered a previously unknown cellular "switch" that may provide researchers with a new means of triggering programmed cell death, findings with implications for treating cancer...

Alterations in our response to the taste or smell of food may be another culprit responsible for Type 2 diabetes, according to scientists at Duke University Medical Center who have identified the specific mechanism in human specimens and in mice...
Biology / Biochemistry News From Medical News Today
The Sam Houston State University Regional Crime Laboratory which will serve the basic needs of nearly 100 state and local law enforcement agencies from the ten counties in southeast Texas is now open, according to university officials...
Biology / Biochemistry News From Medical News Today
What: Scientists studying the Anopheles gambiae mosquito - the main vector of malaria - have found that when the mosquito takes a blood meal, that act triggers two enzymes to form a network of crisscrossing proteins around the ingested blood...
Biology / Biochemistry News From Medical News Today
Cancer cells in rapidly growing brain tumors must adjust to periods of low energy or die. When energy levels are high, tumor cells grow and proliferate. When levels are low, the cells grow less and migrate more. Researchers at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J...
Biology / Biochemistry News From Medical News Today
Conventional biological wisdom holds that living cells interact with their environment through an elaborate network of chemical signals. As a result many therapies for the treatment of cancer and other diseases in which cell behavior goes awry focus on drugs that block or disrupt harmful chemical signals...
Biology / Biochemistry News From Medical News Today
By studying the hydra, a member of an ancient group of sea creatures that is still flourishing, scientists at UC Santa Barbara have made a discovery in understanding the origins of human vision. The finding is published in this week's issue of the Proceedings of the Royal Society B, a British journal of biology. Hydra are simple animals that, along with jellyfish, belong to the phylum cnidaria...
Biology / Biochemistry News From Medical News Today
Infertility affects between 10 and 15 percent of couples worldwide. Surprisingly, problems with male fertility account for approximately 50 percent of infertility cases. A new home test kit based on a protein in sperm discovered by University of Virginia Health System cell biologist John C. Herr, PhD, can assist couples in determining if a man's sperm count is normal, low, or very low...
Biology / Biochemistry News From Medical News Today
A puzzle that has baffled scientists for centuries - why some birds appear to be male on one side of the body and female on the other - has been solved by researchers. The research, which involved studying rare naturally occurring chickens with white (male) plumage on one side and brown (female) plumage on the other, sheds new light on the sexual development of birds...

Louis J. Soslowsky, Ph.D. Fairhill professor of Orthopaedic Surgery and professor of Bioengineering, director of the McKay Orthopaedic Research Laboratory and Penn Center for Musculoskeletal Disorders at the University of Pennsylvania School of Medicine, was named the 2010 winner of the Ann Doner Vaughan Kappa Delta Award by the American Academy of Orthopaedic Surgery...

If you can imagine identical twin sisters at rest, their breath drawing them subtly together and apart, who somehow latch onto ropes that pull them to opposite sides of the bed - you can imagine what happens to a chromosome in the dividing cell...
Biology / Biochemistry News From Medical News Today
Our DNA contains the information needed to produce different proteins that are the building blocks and key components of cells. Instructions to synthesize such proteins are incorporated into DNA sequences defined as genes. This precious genetic material, however, never leaves the cell's stronghold nucleus...
