Researchers Discover Possible Approach to the Treatment of Aggressive Breast Cancer

In particularly aggressive forms of breast cancer, cancer cells can settle in other organs and form metastases there. Once such metastases form, complete recovery is rare. Consequently, it is enormously important to prevent the metastasisation of the breast cancer cells. The success, however, achiev...

New H5N1 Viruses: How to Balance Risk of Escape with Benefits of Research?

In the controversy surrounding the newly developed strains of avian H5N1 flu viruses, scientists and policy makers are struggling with one question in particular: what level of biosafety is best for studying these potentially lethal strains of influenza? In a pair of commentaries, researchers from t...

New Universal Platform for Cancer Immunotherapy Developed by Penn-led Team

Researchers from the Perelman School of Medicine at the University of Pennsylvania report this month in Cancer Research a universal approach to personalized cancer therapy based on T cells. It is the first time a system for making an adaptable, engineered T-cell to attack specific tumor types has be...

Perception and Preference May Have Genetic Link to Obesity

About five years ago, animal studies first revealed the presence of entirely novel types of oral fat sensors or receptors on the tongue. Prior to this time, it was believed that fats were perceived only by flavor and texture cues. With this new information, "everything that we thought we knew about ...

Discovery of a Molecule that Initiates Maturation of Mammalian Eggs Can Lead to More IVF Pregnancies

Women who have eggs that cannot mature will not become pregnant, and they cannot be helped by in vitro fertilization (IVF). Now researchers at the University of Gothenburg, Sweden, have identified a molecule called Cdk1 that has an important function for mammalian egg maturation. In the future this ...

Miniature Pressure Sensors for Medical Touch

The droplet goes in a flexible sandwich of the substance polydimethylsiloxane, or PDMS. The sensor acts as a variable electrical capacitor. When the sensor is pressed down, the sensing droplet is squeezed over conductive electrodes, increasing its capacitance. "There's a huge need for flexible se...
