An Epochal Discovery: A Habitable Planet Orbits Our Neighboring Star One hundred and one years ago this October, a Scottish astronomer named Robert Innes pointed a camera at a grouping of stars near the Southern Cross, the defining feature of the night skies above his adopted Johannesburg. He was looking for a small companion to Alpha Centauri, our closest neighboring star system. Hunched over glass photographic plates, Innes teased out a signal. Across five years of images, a small, faint star moved, wiggling on the sky. It shifted just as much as Alpha Centauri, suggesting its fate was intertwined with that binary system.

Meet Margaret Hamilton, the badass '60s programmer who saved the moon landing Happy moon landing day! July 20, 2015 marks the 46th anniversary of Apollo 11's arrival on the moon. The lunar lander holding Neil Armstrong and Buzz Aldrin touched down at 4:18 PM eastern, and Armstrong became the first human in history to walk on the lunar surface at 10:56 PM. UN experts denounce 'myth' pesticides are necessary to feed the world The idea that pesticides are essential to feed a fast-growing global population is a myth, according to UN food and pollution experts. A new report, being presented to the UN human rights council on Wednesday, is severely critical of the global corporations that manufacture pesticides, accusing them of the “systematic denial of harms”, “aggressive, unethical marketing tactics” and heavy lobbying of governments which has “obstructed reforms and paralysed global pesticide restrictions”. The report says pesticides have “catastrophic impacts on the environment, human health and society as a whole”, including an estimated 200,000 deaths a year from acute poisoning.

Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. Your Favorite Housewares Are Spewing Poison Dust Inside Your Home People buy the nicest homes they can afford. They spend years—sometimes decades—pouring money into nest-feathering by stocking up on creature comforts. It’s no wonder we spend 90 percent of our lives indoors.

Electricity for kids - and everyone else: A simple introduction! Advertisement by Chris Woodford. Last updated: April 14, 2016. Types of Wind Turbines Used Today Capturing the earth’s natural energy through wind was once an abstract idea. Eventually, however, engineers were able to focus the idea and put it into action through innovative technology. Throughout the development of wind turbines, many prototypes were created, and many of the first ones designed are still used today, just with more modern engineering. Here are a few of the different wind turbines we are used to seeing today, and some we definitely are not. Mars interactive panorama: What it looks like to be there Imagine standing on Mars and looking around. Or instead of imagining, check out this interactive panorama. Nearly 300 images taken by two Curiosity rover cameras over the course of 13 days were used to create the best quality images we’ve ever seen of Mars.
Pacific Islanders appear to be carrying the DNA of an unknown human species Hints of an unidentified, extinct human species have been found in the DNA of modern Melanesians - those living in a region of the South Pacific, northeast of Australia. According to new genetic modelling, the species is unlikely to be Neanderthal or Denisovan - two ancient species that are represented in the fossil record - but could represent a third, unknown human relative that has so far eluded archaeologists. "We’re missing a population, or we’re misunderstanding something about the relationships," Ryan Bohlender, a statistical geneticist from the University of Texas, told Tina Hesman Saey at Science News.
