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.
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.

The United Kingdom's National Health Service (NHS) is very popular with people who have no serious issues, because it is free - if they have to wait a few weeks, it is no big deal. For doctors, it isn't so great. The cost to attend medical school is not high, around $15,000 per year, but in their first year they will only earn about $30,000 annually. A specialist is almost 50% higher and that is part of the reason why the UK is losing General Practioners, at the bottom of the wage scale, faster than they can replace them.

There is tremendous controversy about genetically modified (GM) crops and derived food. Even the definition of what is a GM crop can differ depending upon with whom you talk. From a strictly scientific perspective all food has been manipulated at the genetic level by human activity; therefore all foods are genetically modified.
A more scientifically precise term for what goes by the popular term GMOs is genetically engineered (GE). This definition involves the use of recombinant DNA technology in the crop breeding process.-->
Ebola is causing a lot of concern, a few instances in the United States were enough to lead to calls to overthrow the FDA vaccine approval process and the White House declared that the United States Department of Health and Human Services was unqualified to manage a handful of cases in America so they put a lawyer in charge as an Ebola czar. The National Institutes of Health said they could not fix the problem with the $330 billion they have gotten since 2001 but they are just exploiting an outbreak for personal gain also. In reality, the impact of disease outbreaks has been declining on a per capita basis for decades.
The far left in America loves government. Advocacy groups are always calling for new laws, new regulations, new bans and more layers of bureaucracy to put a stop to whatever they dislike. The right is increasingly suspicious of it, regarding every policy as a road to George Orwell's "1984".
That was not always the case. In the 1950s and '60s, it was the left who was on the right and the right was on the left. Government meant law and order and the right was opposed to anarchy and protests promoted by the left.
A diet rich in milk products is promoted as strengthening bones and reducing the likelihood of osteoporotic fractures, but dairy lobby marketing aside, actual research related to the benefits of milk for the prevention of fractures or influence on mortality rates has found evidence for and against.
A new study finds that high milk intake in women and men is not accompanied by a lower risk of fracture and instead may be associated with a higher rate of death.
It's great to insist that people should just accept science and medicine but it isn't really practical. The nature of coastal California is that they don't trust vaccines the way religious people in the American south do, Asians are going to believe in acupucture, and the French will think they can be allergic to Bt genetically modified plants but not Bt organic pesticide spray.
