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.

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.

Ups-and-downs of Indian monsoon rainfall likely to increase under warming Posted: 20 Jun 2013 07:12 AM PDT Day-to-day rainfall in India might become much more variable due to climate change -- potentially putting millions of poor farmers and the country's agricultural productivity at risk.

The sun moth: A beautiful new species Stenoloba solaris from China Posted: 20 Jun 2013 07:12 AM PDT Scientist describe a striking new species of moth from China with an engaging wing pattern. Only a single male specimen of the new species Stenoloba solaris has been found. This beautiful moth had its name inspired by the orange circular patch on its wings that resembles the rising sun.

Why are gull chicks murdered, especially on Sundays? Posted: 20 Jun 2013 04:14 AM PDT Why are gull chicks murdered especially on Sundays? Are humans somehow to blame? Researchers have discovered much more cannibalism takes place over the weekend than on weekdays (gull chicks were pecked to death by adult gulls and sometimes eaten). It turned out that gulls, especially during chick care, rely heavily on fish waste thrown overboard from fishing boats. Bad luck for these birds: at the weekend, the fishing fleet is largely in the harbor.
