Eliminating emissions in India and China can add years to people's lives
About 2.7 billion people who live in China and India- which is more than a third of the world's population-regularly breathe polluted air. According to a recent study, eliminating harmful emissions from power plants could save an estimated annual 15 million years of life in China and 11 million years of life in India.
AstraZeneca's Lynparza shown to put brakes on ovarian cancer
Given as a maintenance therapy to reinforce initial chemotherapy, Lynparza halted or reversed tumour growth in 60 per cent of patients three years into the trial. British drug maker AstraZeneca, which published some initial information on the trial in June, generated $297 million in Lynparza sales last year. Getting patients on Lynparza at an early stage of treatment, so-called first-line use puts AstraZeneca in the frame to secure longer-duration prescriptions. Clovis Oncology's Rubraca has been approved for ovarian cancer after initial chemotherapy has failed.
'Super-sized' mice threat to seabirds
Super-sized mice are killing millions of seabird chicks on a remote island in the South Atlantic, threatening some rare species with extinction. Mice were introduced to the 91-sq-km volcanic island by sailors during the 19th Century. Video cameras have recorded groups of up to nine mice eating the chicks alive. As a result of their success, the mice have become super-sized.
In pictures: Legendary mountain team's 1921 Everest album
British mountaineer George Mallory took his last breath on the imperious slopes of Everest in 1924. Three years before that, he made history as part of the first British reconnaissance expedition to the world's highest peak. Led by soldier and explorer Charles Howard-Bury, this was the first group of Westerners to set foot on Everest. This collection of pictures was digitised by the Salto Ulbeek studio in Belgium from the original silver nitrate negatives.
Researchers explain mechanism behind bendy straws
What we discovered is that the very useful property of being mechanically stable in a bent configuration seems to require pre-stress. The researcher further said, It will be helpful for us to understand this fundamental principle, which is key when designing new applications. If you're going to build a reconfigurable device, it's important to know why it works, and when it might fail. There's no obvious reason why a bendy straw should want to be stable when bent, he added.
Decision-making in single-cell organisms
The tiny organisms demonstrated, in fact, a primitive form of behavioural biology. It is striking that even unicellular organisms that obviously lack a nervous system can process different stimuli and even evaluate their individual needs. We observed that the diatoms moved towards pheromones or food sources depending on how hungry they were for sex or nutrients. Until now, this kind of decision-making has only been attributed to higher organisms, study leader Georg Pohnert summarized the results.
Frances Arnold: 'To expect a Nobel prize is rather silly'
This month, Frances Arnold, professor of chemical engineering at Caltech in California, was awarded the 2018 Nobel prize in chemistry, shared with two others. There are many wonderful chemists whose work deserves the Nobel prize and to expect one is rather silly. Your Nobel prize was awarded for the directed evolution of enzymes. Some people find it remarkable that there are two female winners this year of Nobel prizes because it is usually all men.
Massive piece of space junk falls in California: Details here
Shubham Sharma We all know space junk or tiny flecks of discarded rockets and satellites pose a major threat to manned/unmanned missions. This time, a massive piece of space junk has been found on Earth - and not in space. In context Space junk crashes down to Earth Space junk details The huge piece of space debris, shaped like a dome, was found last week in a walnut orchard in Hanford, California.
Climate change is exacerbating world conflicts, says Red Cross president
Climate change is already exacerbating domestic and international conflicts, and governments must take steps to ensure it does not get worse, the head of the International Committee of the Red Cross has said. Maurer, who was in Australia to speak about the changing nature of modern conflict, said concern about the impact of climate change in the Pacific was enormous. Earlier this month the United Nation's climate panel, the IPCC, gave the world just 12 years to make the drastic but necessary changes.
Carrots could be key to making greener buildings, say researchers
The addition of carrots prevent any cracks in the concrete, the team said. Cement is responsible for seven per cent of total global CO2 emissions, according to International Energy Agency estimates. The carrot particles are provided by CelluComp, a Scottish-based company who work on the development of sustainable materials. With large amounts of vegetable waste available as a byproduct of agriculture, it is a cheap and environmentally friendly source of the fibres.
Europe-Japan joint mission set out for Mercury
Two satellites developed in Europe and Japan are on their way to the Sun's closest planet Mercury. The joint endeavour BepiColombo left Earth on an Ariane rocket that launched out of South America on Friday, the BBC said. It's possible the planet began life much further and later migrated inwards, mission scientist Suzie Imber from Leicester University. At just 58 million km from the Sun, working at Mercury is like being in a pizza oven, Imber said.
Dussehra festivities see Delhi choking again as air quality drops to 'very poor' levels
Delhi's air quality has now dropped down to very poor amid Dussehra festivities. By Saturday evening, a massive haze was seen settling over the city and dropped the quality of air even further, reported NDTV. The pollution levels actually shot up, notes the report right after GRAP emergency measures were put in place by the Delhi government. If the quality of air drops to that level, the Delhi government could block all trucks from entering the city except for essential goods.
China aims to replace street lights with man-made moons
Well, that's the idea China is now mulling upon, though Russia tried moon mirrors in space in mid-1990s under a project called Banner. China is now planning to launch man-made moons to the sky by 2020. The aim is to replace all streetlamps so that, the electricity costs in urban areas can be reduced. Launching artificial moons is not the ambitious space project China is working on currently. If this mission succeeds, China will be the first country to ever explore the moon's dark side.
Mysterious X-37B unmanned Nasa space plane passes 400 days in orbit
The US Air Force's X-37B unmanned space plane (pictured) is nearing one year in orbit as part of its fifth secretive mission. Each time the unmanned space plane has carried a mystery payload on long-duration flights in Earth orbit. The US Air Force's unmanned X-37B space plane looks similar to Nasa's space shuttle but is much smaller. 'It is our goal to continue advancing the X-37B OTV so it can more fully support the growing space community.
Astrophysicist Neil deGrasse Tyson says space exploration could make Earth more peaceful
Astrophysicist Neil deGrasse Tyson, who said he thinks space exploration would be 'the greatest peace driver there ever was' Astrophysicist Neil deGrasse Tyson says space exploration could make Earth more peaceful because wars over resources would vanish. As well as hosting Cosmos, Tyson also produces the podcast Star Talk and is director of the New York Planetarium. Tyson spoke out at a press event in New York for 'Cosmos: Possible Worlds', which he will be hosting for its third series next year.
Giant galaxy supercluster found lurking in early Universe
Scientists have discovered a primitive supercluster of galaxies forming in the early Universe, just 2.3 billion years after the Big Bang. The structure, nicknamed Hyperion, is the largest and most massive to be found so early in the formation of the Universe, which sprang into existence around 13.7 billion years ago. Hyperion is similar in size to nearby superclusters, though it has a very different architecture, the researchers said.
Unique 'fingerprints' can help track 3D-printed guns
Scientists claim to have developed the first accurate method to identify which machine a 3D-printed object came from, paving the way for law enforcement agencies to track the origin of printed guns, counterfeit products and other goods. According to researchers from University at Buffalo in the US, 3D-printers leave unique 'fingerprints' on its products, which can be identified by their PrinTracker. Each layer of a 3D-printed object contains tiny wrinkles - usually measured in submillimetres - called in-fill patterns.
BepiColombo spacecraft starts seven-year journey to Mercury
A European-Japanese spacecraft set off on a treacherous seven-year journey to Mercury to probe the solar system's smallest and least-explored planet. Beyond completing the challenging journey, this mission will return a huge bounty of science. BepiColombo, named after 20th century Italian mathematician and Engineer Giuseppe (Bepi) Colombo, will slingshot off the Earth's gravitational field one-and-a-half years after launch before picking up speed on its journey.
Nobel laureate Donna Strickland: 'I see myself as a scientist, not a woman in science'
Long before the Nobel bestowed its honour, the 59-year-old was considered one of the world's foremost laser physics pioneers. The research that the Nobel committee recognised was published in 1985, when Strickland was still a doctoral student at the University of Rochester in upstate New York. Strickland met her future husband, the electrical engineer and scientist Doug Dykaar, at university. There are a lot of events during Nobel week in December - balls, lectures, concerts, dinners, a meet-and-greet with the Swedish royal family.
Moon chunk that fell to Earth lands $600,000 at auction
A lunar meteorite considered one of the most significant ever found has been sold by a Boston auction house. A chunk of the moon that fell to the Earth as a lunar meteorite has been sold at auction for more than $600,000. The auction house predicted it would fetch $500,000 at auction. The meteorite was found last year in a remote area of Mauritania in north-west Africa. Experts believe it may have plunged to earth thousands of years ago.
