Mice and men express the same olfactory preferences

Humans and mice are attracted by the same odors. This has been revealed for the first time by a team of French researchers in the "Neurosciences sensorielles, comportement, cognition" Unit (CNRS / Université Lyon 1).

Inflammation contributes to colon cancer

Researchers led by Drs. Lillian Maggio-Price and Brian Iritani at The University of Washington found that mice that lack the immune inhibitory molecule Smad3 are acutely sensitive to both bacterially-induced inflammation and cancer.

Newly discovered protein acts as virus alarm

The Center for Molecular Medicine of the Austrian Academy of Sciences (CeMM) announces the discovery of a new molecular sensor in human cells capable of recognizing infecting viruses and transmitting an alarm signal to the body.

MRSA's weak point visualised by scientists

An enzyme that lives in Methicillin-resistant Staphylococcus aureus (MRSA) and helps the dangerous bacterium to grow and spread infection through the human body has been visualised for the first time, according to a study out today in Proceedings of the National Academy of Sciences (PNAS).

How the sensory organs of bacteria function

Bacteria can occur almost anywhere on earth and exist under the most varying conditions. If these tiny, microscopic organisms are to survive in these environments, they need to be able to rapidly detect changes in their surroundings and react to them.

Nanotubes sniff out cancer agents in living cells

A multidisciplinary team at the Massachusetts Institute of Technology (MIT) has developed carbon nanotubes that can be used as sensors for cancer drugs and other DNA-damaging agents inside living cells. The sensors, made of carbon nanotubes wrapped in DNA, can detect chemotherapy drugs such as cisplatin as well as environmental toxins and free radicals that damage DNA.

Artificial antibody delivers nanoparticles to tumors

Antibodies that target epidermal growth factor receptor (EGFR) have proven themselves as potent anticancer drugs. Now, a team of investigators led by Shuming Nie, Ph.D., and Lily Yang, Ph.D., both at the Emory University School of Medicine and members of the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology, is aiming to capitalize on this targeting ability, using a modified anti-EGFR antibody to delivery nanoparticles into tumor cells.
