Unexpected discovery of the ways cells move could boost understanding of complex diseases Posted: 23 Jun 2013 11:51 AM PDT A new discovery about how cells move may provide scientists with crucial information about disease mechanisms such as the spread of cancer or the constriction of airways caused by asthma. Scientists found that epithelial cells move in a group, propelled by forces both from within and from nearby cells, to fill any unfilled spaces they encounter.

The genome's 3-D structure shapes how genes are expressed Posted: 23 Jun 2013 11:50 AM PDT Scientists bring new insights to our understanding of the three-dimensional structure of the genome, one of the biggest challenges currently facing the fields of genomics and genetics.

Getting to grips with migraine: Researchers identify some of the biological roots of migraine from large-scale genome study Posted: 23 Jun 2013 11:49 AM PDT Migraine is an extremely difficult disorder to study. Between episodes, the patient is basically healthy, making the underlying pathology very difficult to uncover. In the largest migraine study, an international team of researchers have identified genetic regions linked to the onset and susceptibility of migraine.

Sugar solution makes tissues see-through Posted: 23 Jun 2013 11:49 AM PDT Japanese researchers have developed a new sugar and water-based solution that turns tissues transparent in just three days, without disrupting the shape and chemical nature of the samples. Combined with fluorescence microscopy, this technique enabled them to obtain detailed images of a mouse brain at an unprecedented resolution.

New player is critical to unleashing T cells against disease Posted: 23 Jun 2013 11:49 AM PDT A major study provides new revelations about the intricate pathways involved in turning on T cells, the body's most important disease-fighting cells. A certain type of protein, called septins, play an essential role in T cell activation.

Americans' vitamin D levels are highest in August, lowest in February, study shows Posted: 22 Jun 2013 12:46 PM PDT Researchers have found that vitamin D levels in the U.S. population peak in August and bottom out in February. The essential vitamin -- necessary for healthy bones -- is produced in the skin upon exposure to ultraviolet B rays from the sun.

Findings emphasize importance of vitamin D in pregnancy Posted: 22 Jun 2013 12:44 PM PDT Pregnant women pass low levels of vitamin D on to their babies at almost three times the extent previously thought, according to new research.
