Along with eating right and exercising, people should consider adding another healthy habit to their list: turning out the lights. That's according to a new study showing many negative health consequences for mice kept under conditions of constant light for a period of months.
Researchers have mapped out the sets of biological and chemical signals necessary to quickly and efficiently direct human embryonic stem cells to become pure populations of any of 12 cell types, including bone, heart muscle and cartilage.
Valve is finally addressing the last week's Counter-Strike gambling scandal. The game maker and Steam operator says that it does not directly profit from these gambling sites' actions. In a statement, Valve's Erik Johnson said the following: We have no business relationships with any of these sites. We have never received any revenue from them. And Steam does not have a system for turning in-game items into real world currency. Johnson added that gambling sites work by creating and maintaining their own Steam accounts, which are used to conduct virtual item trading. He adds:Using the OpenID API and making the same web calls as Steam users to run a gambling business is not allowed by our API nor our user agreements.Steam's user agreement includes a passage that forbids "exploiting the Content and Services or any of its parts for any commercial purpose, except as expressly permitted elsewhere in this Agreement." The company won't block these websites, but says it will begin cracking down on them -- by sending them cease and desist notices.
A checklist used by John Glenn as he became the first American to orbit Earth is now circling the auction block. The document, which Glenn used on his Mercury spacecraft Friendship 7, helped track his activities and the capsule's position.
Dropbox announced on Thursday that it is releasing its image compression algorithm dubbed Lepton under an Apache open-source license on GitHub. Lepton, the company writes, can both compress and decompress files, and for the latter, it can work while streaming. Lepton offers a 22% savings reductions for existing JPEG images, and preserves the original file bit-for-bit perfectly. It compresses JPEG files at a rate of 5MB/s and decodes them back to the original bit at 15MB/s. The company says it has used Lepton to encode 16 billion images saved to Dropbox, and continues to utilize the technology to recode its older images. You can find more technical details here.
In July 2016, the Sun presented us a 'face' which consisted of two active regions and a low-density area, called a coronal hole. Multiple wavelength imagery from NASA's Solar Dynamics Observatory from July 12-14 are presented.
The genes of some chickens make them almost completely resistant to a serious strain of bird flu, new research has revealed. Until now, scientists around the world have paid little attention to the role the genetics of birds play in the transmission of flu, focusing instead on how the virus itself evolves and infects.
A long non-coding RNA (lincRNA) -- called lincRNA-EPS -- responsible for regulating innate immunity has been identified by a team of scientists. This discovery points to an unrecognized role for lincRNAs in the immune system and may lead to new insights into inflammatory diseases caused by uncontrolled immune responses such as lupus or inflammatory bowel disease.
A new study finds that access to some nutrients may be a star player in shaping traits related to fitness such as fecundity and eye size over the long term. Given drastic increases in the availability of many nutrients due to the widespread use of fertilizers and road salts, the finding has important implications for agriculture and ecology.
Cancer treatment in people could be transformed thanks to a study on treating cancer in animals. Injecting oncolytic viruses (viruses that target cancer cells) intravenously into the spleen allows immune responses to be boosted much more rapidly and to much higher magnitudes than traditional vaccine methods.
