Researchers solve structure of proteins known as sodium glucose co-transporters

Researchers at the David Geffen School of Medicine at UCLA have solved the structure of a class of proteins known as sodium glucose co-transporters (SGLTs), which pump glucose into cells.

A noisy brain is a healthy brain

Canadian scientists have shown that a noisy brain is a healthy brain. "Brain noise" is a term that has been used by neuroscientists to describe random brain activity that is not important to mental function.

Breast cancer: How tumor cells break free and form metastases

When tumor cells acquire the capacity to move around and invade other tissues, there is a risk of metastases and cancer treatment becomes more difficult. At the Institut Curie, CNRS Director of Research Philippe Chavrier and his group have just discovered how breast cancer cells break the bonds that tether them to the tumor. The basement membrane around the mammary gland is a barrier to the spread of cancer cells. Three proteins in the tumor cells transport enzymes needed to perforate this barrier, and another protein puts these enzymes in the right place.

Brain food - what we eat affects our intelligence

New research findings published online in The FASEB Journal provide more evidence that if we get smart about what we eat, our intelligence can improve. According to MIT scientists, dietary nutrients found in a wide range of foods from infant formula to eggs increase brain synapses and improve cognitive abilities.

Bacteriophages treat deadly bacterial infections in mice

By the time antibiotics made their clinical debut 70 years ago, bacteria had long evolved strategies to shield themselves. For billions of years, bacteria hurled toxic molecules at each other in the struggle to prosper, and those that withstood the chemical onslaught marched on.
