Having sex in outer space could kill people, according to a study from Montreal University. For the experiment, scientists used a pollen which reproduces very similarly to human beings. They found that the lack of gravity distorts cells when there's an exchange from sexual partners.
The Smithsonian Channel debuts a new true crime series tonight, this one looking at the forensic science investigative tools that have revolutionized the way criminals are caught.
"Forensic Firsts," airing at 9, kicks off the series by examining the history of DNA evidence. They revisit the rape and murder of two girls in Leicestershire, England in 1986, the case that was the first in the world to use DNA evidence against suspects.
The episode mostly talks about the case of the BTK serial killer in Witchita, Kansas, who began killing in 1974 before the technology was in use. But DNA is what finally -- eventually -- got Dennis Rader in 2005.
Researchers at N.C. State University have developed a breakthrough that could have far-reaching impact on industrial and consumer electronics.
The chair of materials science and engineering, Dr. Jay Narayan, and his team at NCSU have developed a thin film that can handle more power and withstand more extreme conditions than solid state silicon electronics that have been in use for decades.
Better heat and radiation resistance makes it more suitable for automotive applications and space technology.
But there is another fascinating property of these oxide films. "These materials are also transparent," Narayan says, "so this makes transparent electronics possible."
Transparent displays, solar cells and embedded biocompatible medical devices are examples of where this technology could be used.
The material is the first functional oxide thin film that can be used efficiently in electronics.
This is the first time that researchers have been able to produce positively charged (p-type) conduction and negatively charged (n-type) conduction in a single oxide material. Using lasers, the team is able to precisely create the crucial positive-negative junctions resulting in greater efficiency.
Oxide films could be used to create higher voltage switches for the power grid, allowing more power to be transmitted on the existing infrastructure. This could make power transmission less expensive.

Here is a quick, but powerful take on the story of a new continuous-flow artificial heart.
Forget about cellphone radiation, it's the bacteria users need to worry about.
In addition to all those apps and music, a study reveals that many mobile phones are contaminated with fecal matter.
London School of Hygiene & Tropical Medicine and Queen Mary, University of London shared the results to highlight Global Handwashing Day. The research conducted in Britain found that more than hands of one in seven users and one in six phones were contaminated with hazardous e. coli bacteria which is found in feces .
That is something to think about the next time you lend or borrow a phone.
A team of scientists genetically modified cats resulting in felines that glow in the dark.
Researches inserted a feline AIDS resistant gene. So the cats with the AIDS resistant trait could be more easily identified, they also inserted the gene for the fluorescent effect. Both genes were injected into feline eggs.
The research may raise the hair on the backs of some animal advocates, but it seems glow-in-the-dark cats have an even more endearing effect online.
Better catch Jupiter next week in the night sky. It won't be that big or bright again until 2022.
There is an initial shock upon first glance at Connie Culp, the woman who received the nation's first face transplant nearly two years ago.
Ordinary computers like those folks use to send e-mail or surf the Internet are being credited with finding a previously unknown neutron star.
