Region’s First MRI-Guided Brain Biopsy At UC San Diego Health System

0 Clark Chen, MD, PhD, neurosurgeon, shares groundbreaking advances in MRI-guided biopsy of brain abnormalities such as glioblastoma. Advanced technologies at UC San Diego Health System such as Restriction Spectrum Imaging (RSI), MRI-based stereotactic guidance, and MRI-compatible biopsy needles enable neurosurgeons to precisely sample abnormal brain tissue with less risk to healthy structures. These advanced imaging approaches ensure that pathologists make a definitive diagnoses based on diseased tissue.

Algae “See” A Wide Spectrum Of Light

0 Phytochromes are pigments that let plants "see" light and adapt to changing conditions. Land plants can only detect red light, but new work from UC Davis shows that algae living in water, which blocks red light, can see a wide spectrum of color.

Where Has Nessie Gone?

0 USA Today reports that this last 18-month stretch without confirmed Loch Ness Monster sightings marks the longest since 1925. One man who keeps a record of the sightings says Nessie’s merely taking a break. There have been 1,036 total sightings dating back over 1,500 years, when the Irish Missionary, St. Columba is said to have encountered the monster. Real or not, both sides have their theories. But here’s a particularly interesting one. Britain’s “High Priest of White Witches” says Nessie is a ghost of a dinosaur.”

Dendrochronology: Tree Rings Record Extreme Weather Cycles

0 A new BYU study documents the extreme 16-year drought in Utah.

BYU Geography Professor Matt Bekker uses dendrochronology (dendro=tree, chronology=time) to reveal extreme weather patterns in the Western US. By taking core samples from trees and measuring tree rings, the BYU research team can correlate patterns in tree rings to weather cycles. The process allows researchers to extend the known climatic history of a region hundreds of years beyond the written history. Such information can be used by water managers to prepare for possible drought cycles in the future. Data collected in Utah revealed an extreme period of drought that spanned 16 years; the event, which occurred in the year 1703, was previously unknown to climatologists.

Get Up And Move! Sitting May Be As Bad As Smoking

0 Recent research says that in some cases, sitting can be equally as bad as smoking when it comes to major cardiovascular risk. One study found that men who spent five or more hours a day sitting were 34% more likely to develop heart failure than those who spent no more than two hours per day sitting. The answer? Not only exercise regularly, but get up from your desk at work at least once an hour and find other ways to move around more throughout your day.
