Measles is one of the most contagious of vaccine-preventable diseases, with the average person with measles capable of infecting 12-18 people if susceptible, and the contagiousness of measles infection highlights gaps in vaccination in the United States that have appeared over the last decade, because of skepticism about childhood vaccination in coastal states like California and Oregon and Washington. In those states, otherwise educated people worry that vaccines may cause autism and would prefer that other children provide herd immunity for theirs.

A recent study compared two of the most commonly performed bariatric surgery procedures.

There are tradeoffs between the two surgical approaches in potential risks and benefits and so there has been an ongoing debate about which can achieve weight loss, with conflicting results in systematic reviews. 

The two procedures were laparoscopic Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (AGB). The result was that RYGB resulted in much greater weight loss than AGB but had a higher risk of short-term complications and long-term subsequent hospitalizations. 

Induced pluripotent stem cells (iPSCs) became the target of researchers a decade ago due to restrictions on federal funding for human embryonic stem cells (hESCs). While media reports were claiming biology was dead if President Bush didn't violate President Clinton's Dickey-Wicker law, researchers instead moved to iPSCs and now they have been able to generate functional, three-dimensional human stomach tissue in a laboratory.

Maggot infestations, rotting carcasses, unidentifiable gunk in the kitchen sink – how much your brain responds to disgusting images could predict whether you are liberal or conservative.

If you don't want to read any further because this is based on functional magnetic resonance imaging and claims that political leaning is a biological trait, here is the short version and you can just rant in the comments: if you are not grossed out, you are a liberal. The authors feel so confident in the result they say they can predict your politics based on a single image with 95 percent to 98 percent accuracy,   

A research team has produced a detailed working image of an enzyme in the Polycomb Repressive Complex 1 (PRC1) related to the BRCA1 breast-cancer protein. PRC1 regulates cell development and is associated with many types of cancer because enzymes like PRC1 turn on or turn off the activity of genes in a cell by manipulating individual chromosome units called nucleosomes. 


Greenpeace is set to launch a series of attacks against crop biotechnology this week. It has scheduled a news conference for Friday titled “Ecological Agriculture, A Climate Resilient Model of Agriculture: The Way Forward,” which purportedly makes  its case against vitamin-enhanced Golden Rice.

The camera and lens that Wally Schirra and Gordo Cooper carried into space during their Mercury Program flights is going up for auction in a few weeks. 

Wally Schirra, a known camera enthusiast, said the Hasselblad camera they used was held in highest regard by photographers for its superior engineering, craftsmanship, and top-of-the-line quality. He reportedly purchased the Hasselblad 500c camera at a Houston photo supply shop in 1962, and brought it back to NASA for mission use preparation.

An organic compound called limonene provides the pleasant smell of cleaning products and air fresheners but some byproducts of these sweet-smelling compounds could be adding to the air while they remove germs and odors.

By cleaning your house, you could be adding smog and ozone to it. 

Aircraft propelled by beams of light rather than fuel? Laser-propulsion just got a step closer thanks to a new method for improving the thrust systems developed by physicists Yuri Rezunkov of the Institute of Optoelectronic Instrument Engineering and Alexander Schmidt of the Ioffe Physical Technical Institute in Saint Petersburg. 

Currently, the maximum speed of a spacecraft is limited by the amount of solid or liquid fuel that it can carry. Achieving higher speeds means that more fuel must be burned—fuel that, inconveniently, has to be carried by the craft and hefted into space. These burdensome loads can be reduced, however, if a laser—one located at a remote location, and not actually on the spacecraft—were used to provide additional propulsive force.

Since the discovery in 2004 of Homo floresiensis, an ancient hominid nicknamed “Flo” and also “hobbit”, after the diminutive villagers from J.R.R. Tolkien’s Lord of the Rings trilogy, due to her small size relative to modern humans, much debate has been raised over the origins of the species.
