Single Algorithm Learns to Play Many Computer Games

Space Invaders is one of the many games that DeepMind’s algorithm has learned to master.

Researchers at DeepMind, a London-based company owned by Google, have created a computer algorithm that can not only learn to play up to 49 different arcade games, but also beat professional human gamers.  This is the first instance in which an artificial intelligence (AI) system can learn many different tasks […]


Human HARE5 Gene Boosts Mouse Brain Size

Scientists have successfully used HARE5, an enhancer that functions in human cortex development, to boost the size of mouse brains.

For a long time, scientists have wondered what distinguishes humans and apes. Once the human and chimp genomes were deciphered about a decade ago, scientists could discover the genetic roots of the human brain size, bipedalism, and the varied diet that makes our species quite successful. Yet, the importance of […]

Scientists from The Scripps Research Institution (TSRI) of Florida potentially discovered an anti-HIV drug so powerful that it could serve as a vaccine for HIV in the near future (1). HIV, human immunodeficiency syndrome, works to compromise an infected individual’s immune system by attacking CD4 lymphocytes, a subtype of white […]


Marijuana turns appetite suppressant into appetite stimulant

Marijuana consumption stimulates the appetite by promoting CB1 activity.

As marijuana use becomes increasingly acceptable, research into the effects of marijuana has recently become more prolific. Tamas Horvath of Yale University and colleagues uncovered the aspects of marijuana use  that triggers appetite and published their results in Nature. Marijuana use stimulates appetite by prompting the CB1 receptor in cells […]

A group of astronomers from the US, Europe, South Africa, and Chile have determined that, approximately 70,000 years ago, a recently discovered star is likely to have passed through the Oort Cloud, a region at the edge of the solar system from which comets arise (1). Its average distance at […]


Mission Statement
