Doping advocates are just as likely to do the brain kind if they do the body kind, according to survey results of about 3,000 hobby triathletes at sporting events in Frankfurt, Regensburg, and Wiesbaden.

The work by Johannes Gutenberg University Mainz (JGU) and Eberhard Karls University in Tubingen was carried out using the randomized response technique, which allows for better estimates of unknown cases in response to sensitive questions. It suggested that 13.0 percent of the athletes surveyed had used illegal and banned substances in the twelve months prior to the survey; 15.1 percent were believed to have engaged in brain doping. revealed that people who engage in physical doping often also take drugs for brain doping.

Inventor and AC electricity proponent Nikola Tesla was on a mission to transmit energy through thin air almost a century ago, but, claims about a conspiracy to keep his work quiet aside, experimental attempts at the feat have resulted in cumbersome devices that only work over very small distances.

The Toyota Research Institute of North America and Duke University have demonstrated the feasibility of wireless power transfer using metamaterials to create a "superlens" that focuses low-frequency magnetic fields over distances much larger than the size of the transmitter and receiver. The superlens translates the magnetic field emanating from one power coil onto its twin nearly a foot away, inducing an electric current in the receiving coil.

Want to be a teenage mother on your way to becoming a porn star? Probably not. The Farrah Abraham career arc has helped in significantly reducing births to teens, according to a new paper.

How could that be determined? It's an economics claim so correlation-causation is not all that stringent.  Wellesley College economist Phillip B. Levine and University of Maryland economist Melissa Schettini Kearney just go ahead and declare that MTV's "16 and Pregnant" and "Teen Mom" did the opposite of what social conservatives thought would happen when teen pregnancy was glorified; they say the shows significantly reduced births to teens, which means we could save billions on sex education classes and putting condoms on bananas and just encourage more reality shows.

A double-blind trial has determined that tea and coffee aren't just morning pick-me-ups, they are also a memory enhancer.

That goes for carbonated drinks containing caffeine also.

Members of the public generally have a negative view of climate engineering, the deliberate large-scale manipulation of the environment to counteract climate change, according to a new paper. This makes some sense. If we can't predict the weather a week from now, it's very difficult to say we can predict the far more complicated climate after physical changes are made to the inputs.

Paranthropus boisei, nicknamed "Nutcracker Man" because of his big flat molar teeth and powerful jaws,lived in East Africa between 2.4 million-1.4 million years ago.

A new paper postulates that he survived mainly on a diet of tiger nuts - edible grass bulbs still eaten in parts of the world today- along with fruits and invertebrates, like worms and grasshoppers.  

Volcanic rock textures and ages suggest that the painting of a mural by residents of Çatalhöyük was recording an explosive eruption of the Hasan Dagi volcano. 

Scientists analyzed rocks from the nearby Hasan Dagi volcano in order to determine whether it was the volcano depicted in the mural from ~6600 BC in the Catalhöyük Neolithic site in central Turkey.

To determine if Hasan Dagi was active during that time, scientists collected and analyzed volcanic rock samples from the summit and flanks of the Hasan Dagi volcano using (U-Th)/He zircon geochronology. These ages were then compared to the archeological date of the mural.

This idea dates back to the Russians in the early 1970s. The surface of Venus is far too hot, and the atmosphere too dense, for Earth life. However, our air is a lifting gas on Venus with about half the lifting power of helium on Earth. A habitat filled with normal air will float high in the dense Venus atmosphere, The atmospheric pressure there is the same as Earth sea level (1 bar). Temperatures are perfect for Earth life too, just over 0°C.

The near-infrared vision of NASA's Hubble Space Telescope has given us a new view deep inside the Tarantula Nebula - and its more than 800,000 stars and protostars within.
