How a High School Senior Won $150,000 By Inventing a $35 Medical Device 

Maya Varma invented a device that cost her only $35 to build and can diagnose five different lung ailments, is already paying dividends. Last week, Varma, now a high school senior, won $150,000 as one of the first place winners in the prestigious Intel Science Talent Search competition.

A born inventor

“I just felt there was something I could do about this,” Varma says matter-of-factly. And why not. The daughter of two Silicon Valley engineers, she has been inventing things for a while now.

In the sixth grade, after she became aware of the dangers of distracted driving, she devised a signaling system that would let drivers know when a stoplight was about to turn red. Last year, she was awarded a patent for that one.

Then, in the eighth grade, she developed a cost-effective way to detect foot neuropathy in patients with diabetes. That won the grand prize in the California State Science Fair.

It also sparked her interest in biomedical research, specifically designing technological solutions to health issues. That’s where she felt she could really make a difference.

First Supernova Shock Wave Image Snapped by Planet-Hunting Telescope

Wow!

For the first time, scientists have seen the shock wave emanating from an exploding star in visible light.

Using NASA’s planet-hunting Kepler Space Telescope, researchers saw the shock wave coming from a massive star explosion (a supernova) that came into Kepler’s view in 2011. The star that ended its life as a supernova is named KSN 2011d, which is nearly 500 times the diameter of the sun, and located about 1.2 billion light-years away.

The shock breakout lasted only about 20 minutes, so Kepler’s ability to catch a glimpse of this event is “an investigative milestone for astronomers,” NASA said.  At the time Kepler observed the explosion, the telescope was gazing continuously at a point in the Cygnus constellation, looking for extrasolar planets. The shock wave observation will give investigators more information into how these shock waves are formed from stellar explosions.

Nixon aide Ehrlichman: ‘War on Drugs’ was tool to target black people and anti-war movement”

“You want to know what this was really all about?” Ehrlichman asked with the bluntness of a man who, after public disgrace and a stretch in federal prison, had little left to protect.

“The Nixon campaign in 1968, and the Nixon White House after that, had two enemies: the antiwar left and black people. You understand what I’m saying? We knew we couldn’t make it illegal to be either against the war or black, but by getting the public to associate the hippies with marijuana and blacks with heroin, and then criminalizing both heavily, we could disrupt those communities.

John D. Ehrlichman (l.), a top adviser to former President Richard Nixon (r.) is seen here in a 1972 photo. Ehrlichman, who died in 1999, admitted that the administration’s "War on Drugs" was actually a ploy to target left-wing protesters and African-Americans.

“We could arrest their leaders, raid their homes, break up their meetings, and vilify them night after night on the evening news. “Did we know we were lying about the drugs? Of course we did.

In 1971, Nixon labeled drug abuse “Public Enemy No. 1” and signed the Comprehensive Drug Abuse Prevention and Control Act, putting into place several new laws that cracked down on drug users. He also created the Drug Enforcement Administration.

By 1973, about 300,000 people were being arrested every year under the law — the majority of whom were African-American.

I think it’s safe to say that when she stops talking to us is when we should be nervous.

Hyenas, Wolves Appear to Strike Cooperative Pact in Negev Desert : Discovery News

In a study recently published in the journal Zoology in the Middle East, scientists from the United States and Israel report sightings of striped hyenas roaming amid packs of grey wolves in the Negev desert.

Neither hyenas nor wolves usually behave very well in their dealings with other carnivores. Hyenas will fight, usurp kills from, and make life miserable for animals from lions to leopards to cheetahs. Wolves, for their part, will make meals out of coyotes and dogs.

The study’s co-authors — University of Tennessee, Knoxville researcher Vladimir Dinets and Israeli zoologist Beniamin Eligulashvili — think the two species traveling together may be an example of animals bending their own rules and instincts a bit, in the name of survival in an extreme, arid landscape.

“Animal behavior is often more flexible than described in textbooks,” said Dinets in a statement. “When necessary, animals can abandon their usual strategies and learn something completely new and unexpected. It’s a very useful skill for people, too.”

(Ironic that this comes out of the Middle East where our species could certainly stand to learn this lesson.)

Manta Rays are First Fish to Recognize Themselves in a Mirror

Giant manta rays have been filmed checking out their reflections in a way that suggests they are self-aware.Only a small number of animals, mostly primates, have passed the mirror test, widely used as a tentative test of self-awareness.

“This new discovery is incredibly important,” says Marc Bekoff, of the University of Colorado in Boulder. “It shows that we really need to expand the range of animals we study.”

Csilla Ari, of the University of South Florida in Tampa, filmed two giant manta rays in a tank, with and without a mirror inside.

The fish changed their behaviour in a way that suggested that they recognised the reflections as themselves as opposed to another manta ray.

They did not show signs of social interaction with the image, which is what you would expect if they perceived it to be another individual. Instead, the rays repeatedly moved their fins and circled in front of the mirror:

This suggests they could see whether their reflection moved when they moved. The frequency of these movements was much higher when the mirror was in the tank than when it was not.

First-month Oregon pot sales tax receipts FAR EXCEED projections 

Oregon’s 300 licensed cannabis retailers sold $13.9 million worth of marijuana in January, generating $3.48 million in taxes, according to a revenue report issued on Thursday.

Oregon’s Liquor Control Commission, charged with regulating the drug, had forecast annual tax revenues of about $8 million during the first two years of legal recreational pot sales.
