Home Appendicitis Test?

The recent discovery of a protein marker linked to appendicitis may drastically simplify the diagnosis of the painful and potentially fatal condition. With current methods of conclusive diagnosis generally limited to expensive CT scans, the arrival of a new urine-based test could be a huge breakthrough in safe, noninvasive methods of detecting appendicitis, possibly saving both money and lives.

Lab Grab - Appendix Test

Dim the lights please!

As "highlighted" in the June 2009 issue of Discover, M.D. Anderson Cancer Center scientists in Texas have recently engineered a DNA dimmer - allowing them to adjust the intensity at which a cell 'glows' by precisely controlling the production of green fluorescent protein (GFP) within the cell.

Halitosis feedback

Bad breath is a notoriously difficult condition to self-diagnose. Since our own noses are connected to our mouths and accustomed to the offending odors themselves, our ability to notice our own halitosis is compromised. Relying on others to tell us is likewise inconvenient and socially problematic.

Molecular Sensor Acts like "Bionic Nose"

Prof. Doron Shabat, of Tel Aviv University's Raymond and Beverly Sackler School of Chemisty, has engineered a new type of molecule that has the power to identify microscopic signs of cancer, elements used in the manufacturing of bombs and even impurities in drinking water.

Demethylation - New Cancer Suspect

Researchers from the Kimmel Cancer Center at Johns Hopkins have discovered evidence that genetic changes occurring outside nuclear DNA may cause more than half of all cancers. Hypermethylation - the build up of chemical bonds on certain cancer-promoting genes - has been proven to turn healthy cells cancerous by disrupting the stop growth signals built into the genes.

Statins may "lessen brain function"

A biophysics professor from Iowa State University reveals the results of a study that shows that pharmaceutical drugs aimed at reducing overall cholesterol levels by inhibiting production in the liver, may also keep the brain from making cholesterol, which is vital to brain function.

The Biology of Love

As Valentine's day fast approaches, we thought we'd take a look at the 'science' behind the feelings felt on this day. Some researchers say that the biological basis of love stems from four tiny areas of the brain that form a "circuit of love".
