New imaging studies reveal mechanics of neuron migration
(PhysOrg.com) -- The development of the brain proceeds a little like the European settlement of North America. The earliest pioneers settled on the east coast with subsequent waves of settlers...
Lupus Drug Shows Promise
Human Genome Sciences' stock soars on clinical trial results for Benlysta.
Network Of Altered Genes Appear To Play Role In Development Of Brain Tumors
The interaction between a network of altered genes appears to play an important role in the development and progression of brain tumors, according to a new study.
Overfishing And Evolution: Fish Fear Their Census-takers
Using snorkelers and SCUBA divers is not the best way to monitor fish populations, if we want to know the evolutionary effects of overfishing. The fish population in coral reef...
Reveal the enemy
Bacterial diseases are usually detected by first enriching samples, then separating, identifying, and counting the bacteria. This type of procedure usually takes at least two days after arrival of the...
Research sheds light on cause of Down syndrome and other genetic disorders
Scientists have a better understanding of what causes an abnormal number of chromosomes in offspring, a condition called aneuploidy that encompasses the most common genetic disorders in humans, such as...
The Migration of Trees ... With Some Help
Geneticists Plant Non-Native Seedlings in Canada, U.S. to Study Species' Survival Against Climate Change
Genetic Circuit That Regulates Behavior Of Stem Cells Discovered
This circuit explains the fact that stem cells are always prepared to change into any type of cell. The discovery will greatly increase the ability of researchers to maintain embryonic...
Little bacteria at Island slaughterhouses
A survey of P.E.I. provincially inspected slaughterhouses shows they are keeping potential food-poisoning bacteria in check, but five of the 13 processors decided not to participate in the survey.
Edible Coating Makes Fish Fillets Longer-lasting, Healthier
Consumers may soon be able to eat longer-lasting, potentially healthier fish filets. Scientists have extended the shelf life of lingcod fillets and made them more nutritious by dipping them into...
Global Model For The Origin Of Species Independent Of Geographical Isolation
Using a computer to settle the debate over the origin of species independent of geographic isolation, researchers developed a global model without boundaries and ecosystem niches. The study's biodiversity results...
Gliomas Exploit Immune Cells Of The Brain For Rapid Expansion
Gliomas are among the most common and most malignant brain tumors. These tumors infiltrate normal brain tissue and grow very rapidly. As a result, surgery can never completely remove the...
New Information About DNA Repair Mechanism Could Lead To Better Cancer Drugs
Researchers have shed new light on a process that fixes breaks in the genetic material of the body's cells. Their findings could lead to ways of enhancing chemotherapy drugs that...
Secrets Of A Life-giving Amino Acid Revealed
Selenium is a trace element crucial to life -- too little or too much of it is fatal. Scientists now detail the molecular mechanisms that govern its metabolism in the...
Early-life Experience Linked To Chronic Diseases Later In Life
People's early-life experience sticks with them into adulthood and may render them more susceptible to many of the chronic diseases of aging, according to a new study.
Clone patrol - sniffer-dogs report for duty in South Korea
The world's first cloned sniffer dogs, all called Toppy, report for duty in South Korea.
Controlling Red Imported Fire Ants Two Ways
Two separate strategies for reducing the spread of red imported fire ants (RIFA) are being combined by scientists as part of a strategy that could potentially add to the arsenal...
Controlling Kudzu With Naturally Occurring Fungus
Kudzu, "The Vine that Ate the South," could meet its match in a naturally occurring fungus that scientists have formulated as a biologically based herbicide.
Why North America Black Cherry Tree Is Invasive In Europe
Black cherry trees, native to the United States, are an invasive species in Europe and thrive in that part of the world. Experiments show why: A soil-borne pathogen keeps these...
'Weedy' Bird Species May Win as Temperatures Rise
Climate change is altering North American winter bird communities in ways that models currently favored by ecologists fail to predict.
Mathematics Taking Guesswork Out Of Plastic Surgery Tissue Transfer
Plastic surgeons are turning to mathematics to take the guesswork out of efforts to ensure that live tissue segments that are selected to restore damaged body parts will have enough...
Moles And Melanoma: Genetic Links To Skin Cancer Found
Research shows the genetic connection between moles and melanoma -- and why the more moles a person has, the more susceptible they are to the disease. Researchers found a clear...
Chemicals Found In Fruit And Vegetables Offer Dementia Hope
A group of chemicals found in many fruits and vegetables, as well as tea, cocoa and red wine, could protect the brain from Alzheimer's disease, a dementia expert reports.
Ralph F. Hirschmann, Leading Scientist on Early Enzyme Research, Dies at 87
Mr. Hirschmann was a leader of a team of biochemists that for the first time synthesized an enzyme, one of the master chemicals of life.
Professor sheds light on DNA mechanisms
