Want to boil water in less than a trillionth of a second?

Now you can, if you are at the Hamburg Center for Free-Electron Laser Science and can find someone to build your theoretical concept.

Still, heating water 600 degrees Celsius in just half a picosecond seems like a fun application. If it ever does get built, it will be the fastest water-heating method on earth.  

It seems like common sense to want to avoid foodborne illnesses but the naturalistic fallacy regarding food has extended to milk - with claims that raw milk somehow wards off disease and is better for you.

While no one should drink it if they aren't absolutely sure how it was produced, like cigarettes, raw milk should especially be avoided by pregnant woman and kids.

A new policy statement by the American Academy of Pediatrics

Americans' perceptions of income inequality are largely over-inflated due to political and cultural grandstanding, at least when compared with actual census data.

Most science fiction and news stories describe Mars terraforming as a long term but simple process. You warm up the planet first, with greenhouse gases, giant mirrors, impacting comets or some such. You land humans on the surface right away and they introduce lifeforms designed to live on Mars. Over a period of a thousand years or so, life spreads over the planet and transforms it, and Mars becomes a second Earth.

In America, where the Obama administration is using surveillance cameras, tracking website visits and monitoring citizens using GPS, many people feel their privacy is slipping away.

It's no surprise that, if there is a choice, like with electronic health records, people out opt - at least until the Afforadable Care Act requires it. Already, health records and clinical tissues are being used for medical research purposes, even without patient consent but completely compliant with federal regulations. 

Like most government spending programs, once environmental lobbyists got their way and renewable ethanol biofuels became mandated and subsidized, they have been difficult to eliminate.

Perhaps the news that blending more ethanol into fuel to supposedly cut air pollution from vehicles carries a hidden risk of toxic or even explosive gases in buildings may help. 

Those problems would likely occur in buildings with cracked foundations that happen to be in the vicinity of fuel spills. Vapors that rise from contaminated groundwater can be sucked inside, according to Rice University environmental engineer Pedro Alvarez. Once there, trapped pools of methane could ignite and toxic hydrocarbons could cause health woes, he said.

In 1989 the CDF experiment was sitting on its first precious bounty of proton-antiproton collisions, delivered by the Tevatron collider at the unprecedented energy of 1.8 TeV. One of the first measurements that was produced was the measurement of the mass of the Z boson, which was at the time known with scarce precision by the analysis of a handful of candidates produced by the CERN SppS collider, at a third of the Tevatron energy. 

Short term over-eating is no problem - just don't make a habit of it and you will be fine, according to a paper in The Journal of Physiology and thousands of years of common sense.

Some studies have said that even a few days of excess calorie intake, where you consume more calories than you burn, brings detrimental health impacts, but the new paper found that a daily bout of exercise generates vast physiological benefits even when you consume thousands of calories more than you are burning. Exercise clearly does a lot more than simply reduce the energy surplus. 

Astronomers have discovered huge active plumes containing water vapour being released from the surface of Jupiter's moon Europa. 

Jupiter's moon Europa has been a focus of extraterrestrial research for some time now as there were clear indications that it harbors a liquid ocean beneath its icy crust. Lorenz Roth of the Southwest Research Institute in San Antonio, Texas and Joachim Saur of the University of Cologne have used the NASA/ESA Hubble Space Telescope to prove that there is water vapor erupting near its south pole.

The water plumes are in comparison to earth geysers immensely large and reach heights of approximately 200 km. Europa has a circumference of 3200 km and is thereby comparable in size with the Moon.

Patients receiving the widely used anesthesia drug etomidate for surgery may be at increased risk or mortality and cardiovascular events, according to a study in Anesthesia&Analgesia which adds to safety concerns over etomidate's use as an anesthetic and sedative drug.

The study assessed the risk of adverse outcomes in patients receiving etomidate for induction of anesthesia. Rates of death and cardiovascular events in about 2,100 patients receiving etomidate were compared to those in a matched group of 5,200 patients receiving induction with a different intravenous anesthetic, propofol. All patients had severe but non-critical medical conditions— ASA physical status III or IV—and were undergoing noncardiac surgery.
