Beta Pictoris is a young star, only about 20 million years old, located about 63 light-years from us. It is surrounded by a huge disc of material, a very active young planetary system where gas and dust are produced by the evaporation of comets and the collisions of asteroids.

By sequencing the genomes of tumor cells, thousands of genetic mutations have been linked with cancer.

Sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process but MIT researchers have now developed a new way to model the effects of these genetic mutations in mice. Their approach, based on the genome-editing technique clustered regularly interspaced short palindromic repeats (CRISPR) is much faster than existing strategies, which require genetically engineering mice that carry the cancerous mutations.

A new paper finds that the same specialized immune cells that patrol the body and spot infections also trigger the expansion of the immune organs known as lymph nodes.

The immune system defends the body from infections but can also spot and destroy cancer cells and lymph nodes are at the heart of this response, but it was unclear how they expand during disease. 

Researchers  at Cancer Research UK's London Research Institute found that when a type of immune cell known as dendritic cells recognizes a threat, they make a molecule called CLEC-2 that tells the cells lining the lymph nodes to stretch out and expand to allow for an influx of disease fighting cells. 

Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as water bottles, dental composites and resins used to line metal food and beverage containers. 

It is also used in thermal paper cash register receipts and a new paper finds that is cause for concern. BPA has not been found to be harmful by the Centers for Disease Control, they say levels from all sources is 1/1000th safe levels for the US, the EU and Canada, but it is controversial due to publicity by environmental groups and the guilt-by-association taint of endocrine disruption.  The FDA agrees.

NOAA's GOES-East Satellite captured the birth of Tropical Depression Nine formed over the western Bay of Campeche, Gulf of Mexico and is forecast to make a quick landfall on Mexico's Yucatan Peninsula.

The clouds associated with the depression stretched over the Yucatan Peninsula and into the western Caribbean Sea were captured on Oct. 22nd at 1600 UTC (12 p.m. EDT).

When is an immigration crisis not an immigration crisis? When people who do not live where it is happening change the definition of an immigration crisis.

A new paper from Rice University's Baker Institute for Public Policy examines historical immigration data, the "push" and "pull" factors currently motivating Mexicans and Central Americans to migrate to the U.S. and then attempts to explain why current undocumented immigration streaming across the Mexican border is not a crisis.
