Scientists have detected subtle changes that may make the bowel more vulnerable to tumor development. One of the mechanisms controlling gene activity is the "epigenetic code," a set of chemical tags attached to the DNA molecule. Changes in the epigenetic code may begin to occur in apparently normal tissues, and the scientists are investigating whether diet could control these changes and delay or reverse the onset of cancer.

This year may set records for tornadoes and tornado-related deaths. "We have already seen more than 115 tornado-related deaths, making this the deadliest tornado season since 1998," said a meteorologist at NOAA's Storm Prediction Center. "It is only the third time since the 1974 super tornado outbreak that there have been more than 100 tornado-related deaths during a single tornado season in the U.S.," a research meteorologist at NOAA's National Severe Storms Laboratory added.

Due to the enormous progress in fabrication and characterization techniques, novel magnetic materials have been widely applied, for instance as magnetic sensors in cars (angle or position sensors). Magnetic sensors are made of thin layers with different magnetic properties. With the help of ion technology, scientists were now able to shrink these multilayer systems down to one layer, retaining their magnetic properties. This discovery could make magnetic sensors even more powerful. Source: ScienceDaily: Latest Science News | 15 Jun 2008 | 12:00 am
Wilkins Ice Shelf has experienced further break-up with an area of about 160 square kilometers breaking off from May 30-31, 2008. ESA's Envisat satellite captured the event -- the first ever-documented episode to occur in winter. Source: ScienceDaily: Latest Science News | 15 Jun 2008 | 12:00 am
Researchers have updated charts that show an American's risk of dying from a given cause over the next ten years, based on age, sex and smoking status. At all ages, men have a higher risk of death from all causes combined, relative to women. For both men and women, smoking increases the risk of death by nearly the same magnitude as adding approximately 5 years to a person's age.

A team of scientists has discovered new information about how Fragile X Syndrome interferes with signaling between the nucleus of neurons and the synapse, the outer reaches of the neuron where two neurons communicate via chemical and electrical signals. The discovery should help lead the way to the development of new treatments for FXS, the most common form of inherited mental retardation and also a genetic contributor to some types of autism and epilepsy.

Variations in a gene within the family of bacteria that causes syphilis may hold clinical, epidemiological and evolutionary significance. Researchers have identified sequence variations in the acidic repeat protein gene that allow straightforward differentiation of venereal syphilis from non-venereal Treponema pallidum subspecies.

LiveScience.com - A prospecting geologist stumbled upon a ragtag bunch of bones in the northern part of British Columbia, more than three decades ago. A new study suggests these fossils could represent a new species of dinosaur.
But beyond that, the dinosaur's identity is a mystery - sort of a Dino Doe.
The small collection of bones includes seven shin, arm and toe bones, as well as a possible skull fragment. Based on the shapes and sizes of the bones, paleontologists think they could have belonged to a type of small- to medium-sized dinosaur, possibly a pachycephalosaur or ornithopod. ... Source: Yahoo!
