Cell Study Explains Why Younger People More At Risk Of Variant Creutzfeldt-Jakob Disease (vCJD)
- ScienceDaily
- 09/10/15 04:30
Specific cells within the immune system could help explain why younger people are more susceptible to variant Creutzfeldt-Jakob disease -- a rare, degenerative, fatal brain disorder. Patients diagnosed with variant CJD are, on average, 28 years old but it has been unclear why older people are not as affected by the...
Plants Recognize Siblings: ID System In Roots
- ScienceDaily
- 09/10/15 04:30
Plants may not have eyes and ears, but they can recognize their siblings, and researchers have discovered how. The ID system lies in the roots and the chemical cues they secrete. The finding not only sheds light on the intriguing sensing system in plants, but also may have implications for agriculture and even home...
Rip Currents Pose Greater Risk To Swimmers Than To Shoreline, Study Suggests
- ScienceDaily
- 09/10/15 04:30
Rip currents -- powerful, channeled currents of water flowing away from the shore -- represent a danger to human life and property. Rip currents are responsible for more than one hundred deaths on our nation's beaches each year, and if rip currents persist long enough they can cause beach erosion. However, researchers found that rip currents along at least one beach in Long Island, New York lasted...

Arctic Has Potential To Alter Earth's Climate: Arctic Land And Seas Account For Up To 25 Percent Of World's Carbon Sink
- ScienceDaily
- 09/10/15 04:30
In a new study, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. Under current predictions of global warming, this Arctic sink could be diminished or reversed, potentially accelerating predicted rates of climate...
Baseball Guru Says Yankees, Dodgers Should Make World Series

With the League Championship Series set to begin tomorrow, NJIT Mathematics Professor Bruce Bukiet has, once again, analyzed the probability of each team winning their post-season series. Bukiet updates his calculations daily during the Major League Baseball post-season.
Researchers Identify Workings Of L-form Bacteria
- ScienceDaily
- 09/10/15 04:30
Researchers have for the first time identified the genetic mechanisms involved in the formation and survival of L-form bacteria. L-form bacteria, which were first discovered in the 1930s, are morphological variants of classical bacteria that lack a cell wall. These bacteria are believed to form in response to cell wall stress from certain antibiotics or the body's immune attack, and are suspected...
'Molecular Trigger' For Sudden Death In Epilepsy Found
- ScienceDaily
- 09/10/15 04:30
The most common gene for long QT syndrome triggers epileptic seizures and could explain sudden unexpected death in epilepsy, say researchers in a new study.
Absent Pheromones Turn Male Flies Into Lusty Lotharios
- ScienceDaily
- 09/10/15 04:30
When researchers genetically tweaked fruit flies so that they didn't produce certain pheromones, they triggered a sexual tsunami in their laboratory. In fact, they produced bugs so irresistible that normal male fruit flies attempted to mate with pheromone-free males and even females from a different species -- generally a no-no in the fruit fly dating...
First-of-kind Study Shows Model Can Be Used To Rate Courtroom Psychiatric Experts Performance
- ScienceDaily
- 09/10/15 04:30
What does it mean when expert psychiatric witnesses in a court case reach opposing conclusions on the same sets of evidence? A new study suggests via mathematical modeling that both analyses can be completely accurate.
Noncorrectable Vision Problems Associated With Shorter Lifespan In Older Adults
- ScienceDaily
- 09/10/15 04:30
Visual problems that cannot be corrected are associated with increased risk of death among individuals between the ages of 49 and 74, and all visual impairments may be associated with the risk of death in older adults, according to a new report.
Culture Is More Important Than Genes To Altruistic Behavior In Large-scale Societies
- ScienceDaily
- 09/10/15 04:30
Socially learned behavior and belief are much better candidates than genetics to explain the self-sacrificing behavior we see among strangers in societies, from soldiers to blood donors to those who contribute to food banks.
Internet Services: Researchers Save Electricity With Low-power Processors And Flash Memory
- ScienceDaily
- 09/10/15 04:30
Researchers have combined low-power, embedded processors typically used in netbooks with flash memory to create a server architecture that is fast, but far more energy efficient for data-intensive applications than the systems now used by major Internet services.
What Drives Our Genes? Researchers Map The First Complete Human Epigenome
- ScienceDaily
- 09/10/15 04:30
Although the human genome sequence faithfully lists (almost) every single DNA base of the roughly 3 billion bases that make up a human genome, it doesn't tell biologists much about how its function is regulated. Now, researchers provide the first detailed map of the human epigenome, the layer of genetic control beyond the regulation inherent in the sequence of the genes...
Earlier Flu Viruses Provided Some Immunity To Current H1N1 Influenza, Study Shows
- ScienceDaily
- 09/10/15 04:30
Researchers studying the 2009 H1N1 influenza virus, formerly referred to as "swine flu," have identified a group of immunologically important sites on the virus that are also present in seasonal flu viruses that have been circulating for years. These molecular sites appear to result in some level of immunity to the new virus in people who were exposed to the earlier influenza...
Gene Mingling Increases Sudden Death Risk
- ScienceDaily
- 09/10/15 04:30
Medical researchers report that variations in the gene NOS1AP increase the risk of cardiac symptoms and sudden death in patients who have an inherited cardiac disease called congenital long-QT syndrome. The findings will help in assessing the risk of sudden death -- and assigning therapy -- in patients with this...
China's Acid Rain Control Strategy Offset By Increased Nitrogen Oxide Air Pollution
- ScienceDaily
- 09/10/15 04:30
Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution control program will be largely offset by increases in nitrogen emissions, which the country's current policy largely...
