The epidemiological study was nicknamed the "Beach Bum Survey". The project recruited 143 regular surfers, body surfers and bodyboarders from around the United Kingdom. Each was asked to recruit a non-surfing friend of the same sex and approximate age and who lived in the same part of the country to serve as a control, which resulted in a control group of 130....

Whitson was greeted with flowers, a pair of sunglasses and a medical team. All three arriving on the capsule, Whitson, fellow top-ten endurance astronaut Fyodor Yurchikhin, and NASA astronaut Jack Fischer, were carried from the capsule in chairs because they were no longer used to Earth's gravity. Because of Hurricane Harvey, which flooded the Johnson Space Ce...

Sun's mood swings not so strange after all, say scie...
The Sun has long been known to go through eleven-year cycles of high and low activity, including sunspots, which Strugarek likened to solar volcanoes. As the magnetic disruption from a sunspot approaches Earth, it can intensify the Aurora Borealis and Australis but it also dings the performance of satellites and power grids. During these periods, the sun's mag...

Days after the Whanganui River was identified as living being in New Zealand, Uttarakhand's high court ruled in favour of granting the two rivers — Ganga and Yamuna — status as living persons. The bench of justices Rajeev Sharma and Alok Singh hearing a related case ruled the rivers "legal and living entities, having the status of a legal person with all corre...

Analysis shows the chemical index of alteration fluctuated over time in a way that suggested the lake varied between hot, wet periods and colder, drier periods. The shallow water would have been rich in oxidants brought in from the atmosphere and groundwater, and the deeper water would have been oxidant poor. Phosphates, carbon, nitrogen, iron and sulfur, indi...

The University of Exeter's lead exoplanet modeller, Dr. Nathan Mayne, in remarks to Wired, said, "If, and it is a huge if, the composition of the atmosphere was Earth-like then we showed the planet could indeed support temperatures which would allow liquid water on the surface". In another statement, he emphasized researchers could also "exploit this to hopefu...

President Trump tells NASA to aim for Mars
On Tuesday U.S. President Donald Trump signed a bill authorizing US$19.5 billion in funding for the 2018 fiscal year to go to the National Aeronautics and Space Administration (NASA) and specifically naming the exploration of Mars as one of the agency's goals. According to Senator Ted Cruz, NASA has not been the recipient of this kind of authorization bill for...

Former NASA astronaut Eugene Cernan dies aged 82
Eugene Cernan, former NASA astronaut and the most recent human to walk on the Moon, died on Monday aged 82, according to a NASA statement. Cernan, who commanded the Apollo 17 mission to the Moon in 1972, was in Houston, Texas, at the time of his death. Cernan, who was born in Chicago, Illinois, on March 14, 1934, earned engineering degrees from Purdue Univers...

Around 7,100 cheetahs remain, say experts
According to a study published on Monday in the Proceedings of the National Academy of Sciences, the cheetah (Acinonyx jubatus), is down to 7,100 individuals remaining worldwide, most of them in Africa and, rarely, in Asia. The number establishes cheetahs as much less commonplace than just over one hundred years ago. There are now scientists calling for the...

On Friday, European Space Agency's (ESA) spacecraft Rosetta ended its mission, crashing into Jupiter-family comet 67P/Churyumov–Gerasimenko. Rosetta is the first spacecraft to orbit a comet; it traveled in space for twelve years and about eight billion kilometres (about five billion miles). 3-D model of Rosetta. The actual Rosetta is black. Image: IanShaz...

Final panel added to China's FAST radio telescope
On Sunday China announced the final panel attached to its telescope named Five hundred meter Aperture Spherical Telescope (FAST). This piece marks the end of a five-year-long US$180 million (CNY¥1.2 billion) construction project. FAST comprises about 4,500 panels and spans a diameter of 500 meters (about 1640 feet). The telescope is part of a series of ventur...

Recent surveys indicated coral bleaching has killed more than a third of coral in the Great Barrier Reef's north and central regions. "All of this", said Mr Shorten, "is at risk if serious action is not taken to protect it. The Great Barrier Reef is an environmental treasure Australia holds on trust for the world". The Australian Research Council (ARC) Centre...

NASA releases first topographical map of Mercury
On Friday, the National Aeronautics and Space Administration (NASA) released the first ever global digital elevation model (DEM) of Mercury. The DEM was created using data gathered by NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft, including over 100,000 photographs, and shows a variety of Mercury's topographical...

NASA releases complete image of Pluto's crescent
On Thursday, NASA released the first complete picture of Pluto's crescent from the New Horizons probe. The probe captured the image with its Multi-spectral Visible Imaging Camera (MVIC) on July 14, fifteen minutes after closest approach to the planet. After nine years' journey, New Horizons made closest approach to Pluto on July 14 and released the first co...

After Mars, NASA announces water ice on Pluto
NASA released yesterday the first coloured pictures of Pluto's blue atmosphere and water ice on the surface taken by the space probe New Horizons. NASA said the haze particles may be grey or red in colour, but the scattering of light producing blue colour indicates the size of the particles. Smaller particles results in the scattering of the blue light. Scien...

NASA announces water on Mars
On Monday, NASA announced that signs of liquid water have been found on Mars. The Mars Reconnaissance Orbiter spacecraft found evidence of the liquid on the Martian surface, in long dark spots on the Red Planet thought to be formed because of water flow. In a news conference, NASA's planetary science director, Jim Green said, "We now know Mars was once a plan...
