TEST RUN FOR DRIVERLESS TRAIN

7 weeks ago
Beijing’s first driverless subway line started test runs on Monday, preparing to start service by the end of this year. The Yanfang line will serve the southwestern suburb Fangshan and be the first domestically developed automated subway on the mainland, according to First Engineering Co. Ltd. of China Railway Electrification Bureau Group. The maximum speed on the line will be 80 km per hour, and trains will have a capacity of 1,262 passengers, reports Xinhua news agency. According to the city’s five-year plan on rail construction, the total length of operational rail in the city will exceed 900 ...

OLDEST HUMANS EXISTED IN NORTHERN AFRICA

In a surprising and controversial geographic twist, researchers claim that the earliest known remains of the human species, Homo sapiens, have turned up in northwestern Africa. Fossils attributed to Homo sapiens and stone tools unearthed at Jebel Irhoud, Morocco, date back to apprximately 300,000 years ago, an international team of researchers reported in two papers in prestigious science journal Nature.  Until now, the oldest human fossils came from East Africa and dated to around 195,000 years ago. Although Homo sapiens might have emerged in East Africa, some researchers also categorize a previously discover...

WILDFIRE SMOKE MAY BE BAD

9 weeks ago
Smoke from wildfire worldwide could impact the atmosphere and climate much more than previously thought, new research using data collected during NASA airborne science campaigns has found. Brown carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the Sun -- sometimes cooling the air and at other times warming it, the findings showed. “Most of the brown carbon released into the air stays in the lower atmosphere, but we found that a fraction of it d...

NASA ON NEUTRON STARS

9 weeks ago
NASA is set to launch the world’s first mission devoted to studying rapidly spinning neutron stars, the densest objects in the universe. The US space agency plans to launch the Neutron Star Interior Composition Explorer, or NICER, aboard SpaceX CRS-11, a cargo resupply mission to the International Space Station, now rescheduled to be launched aboard a Falcon 9 rocket on Saturday.  The SpaceX cargo resupply mission was earlier scheduled for launch last week. The launch was aborted due to bad weather.  About a week after its installation aboard the International Space Station as an external att...

MOON FOUND AROUND DWARF PLANET

11 weeks ago
Combining the power of several space observatories, including NASA’s Hubble Space Telescope, astronomers have uncovered a moon orbiting the third largest dwarf planet, catalogued as 2007 OR10. The pair resides in the frigid outskirts of our solar system called the Kuiper Belt, a realm of icy debris left over from our solar system’s formation 4.6 billion years ago. The team uncovered the moon in archival images of 2007 OR10 taken by Hubble’s Wide Field Camera 3.  Observations taken of the dwarf planet by NASA’s Kepler Space Telescope first tipped off the astronomers of the possibility of...

MAKING CLEAN FUEL FROM HUMAN WASTE

11 weeks ago
Poultry farmer Josephine Mbithe used to get up three times a night to add charcoal to her stove just to keep her newborn chicks warm. But since she started using fuel briquettes made with human waste, the stove burns all night, leaving her to sleep in peace. Mbithe is one of many Nakuru residents who have embraced the briquettes manufactured from human poo and sawdust collected around the town, northwest of Nairobi, in the Great Rift Valley. Before the briquettes find their way into Nakuru’s poor households, they undergo processes to ensure they are free from harmful pathogens that could cause diseases, and are...

OCEAN POLLUTION DATA CRUNCHER

12 weeks ago
India is all set to opt for automatic observation of pollution in the ocean to crunch data that will aid the tourism industry and could also come in handy in countering allegations levelled by developed nations against the country being a major polluter, according to a scientist. “We have proposed a completely new project to automatically observe pollution in the ocean and see whether we can mimic that observation using a mathematical model. We will use those observations to understand the processes which are going on in the coastal waters and provide an estimation of the water quality,” SSC Shenoi, Director, ...

CAMEL’S PAY SCHOOL FEES?

14 weeks ago
Normally droughts lead to the early marriage of girls, as Africa’s pastoralist families look for dowry payments to help cushion the impact of livestock losses. But this time, something unusual is happening: Hard-hit herder families are instead selling drought-threatened livestock and using the money - along with government cash payments - to keep girls in school. “It is no longer profitable to exchange our young daughters with livestock, because when the animals die of drought, it is like we have lost the girl,” Joyce Apus Ipapai, a mother of eight from Lorengelup village, told the Thomson Reuters Foundation. Her 18-year-old daughter, Mercy Lopungre, is one of 150 gir...

Irene Moyo, a cook at Phangani Vocational Training Centre, no longer wakes up at dawn to prepare breakfast for the students. Until the institution installed a manure-fed biogas digester three years ago, the mother of five spent two hours a day collecting firewood in the nearby mountains to meet the school’s heating and cooking needs.  “It was very exhausting ... because of the distance to the mountain, chopping firewood and pushing the wheelbarrow,” said 43 year-old Moyo, who works in Matabeleland South province in southwestern Zimbabwe. “It became much tougher when it was wet, as firew...

CLEANING AIR OF CARBON DIOXIDE

Researchers have found a way to trigger a process similar to photosynthesis in a synthetic material, turning greenhouse gases into clean air and producing energy – all at the same time. The process has great potential for creating a technology that could significantly reduce carbon dioxide, a greenhouse gas linked to climate change, while also creating a clean way to produce energy. “This work is a breakthrough,” said one of the researchers Fernando Uribe-Romo, Assistant Professor at University of Central Florida in the US. The researchers created a way to trigger a chemical reaction in a syn...

SCIENTISTS FIND SUPER-EARTH

15 weeks ago
An international team of astronomers has discovered a so-called “super-Earth” that could contain liquid water, a situation that would make it a very good candidate for harbouring life. Super-Earth is a rocky, temperate planet orbiting a red dwarf star, Efe news agency reported. In an article published on Wednesday in Nature magazine, the scientists say that the distant planet, dubbed LHS 1140b, is orbiting an M class red dwarf star a little smaller and dimmer than the Sun but the most common type of star in our galaxy. The super-Earth and its parent star are located in the constellation Cetus, the Whale, 39 ligh...
