‘COCKTAIL GEO-ENGINEERING PROPOSED

36 weeks ago
New research from an international collaboration of atmospheric scientists, including from India, has explored for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases. Carbon dioxide emissions from the burning of coal, oil and gas not only cause the earth to get hotter but also affect weather patterns around the world. Management approaches need to address both warming and changes in the amount of rainfall and other forms of precipitation.  The team which includes Carnegie Institu...

Self-cleaning public toilets now a reality

38 weeks ago
A new automated self-cleaning public toilet was officially opened at the Canley Vale Town Centre, Australia, recently. Before this toilet, there used to be two sets of toilets available for the Canley Vale Centre which was demolished for the construction of a commuter car park.“The business community was great in opening their doors to people who needed to go to the toilet, but we needed our own toilet,” Mr Fornasier said. “We had mothers with children and people coming from the train station and it was a concern because every corner was blessed. “I was putting pressure on the council and they have responded and it is a great thing for the community. A...

Traditional medicine threatens Myanmar’s elephants

39 weeks ago
Trade in elephant skin for use in traditional medicine has increased in Myanmar, alarming conservationists and authorities who have monitored the species’ decline. Hand-sized coarse pieces of elephant skin are available for sale in major markets in the country and are sought by clients for their medicinal properties as per local beliefs. “We have always seen elephant skin for sale. The problem is not new, but yes, the demand is growing,” Chris Shepherd, the Southeast Asia director of wildlife trade monitoring network TRAFFIC, told Efe news. Shepherd said the network had found elephant skin in areas as diverse as the Mongla region in eastern Myanmar, borderin...

HERITAGE TOILET’S FUTURE AT STAKE

39 weeks ago
The latest heritage building to have its future scrutinized is the oldest public toilet in Dunedin. Built in 1912, its doors were bricked up after 1976 and the interior was preserved.The building is octagonal that appears to be leaning. It also has a huge crack in its brickwork on one of the walls. Jendi Paterson, Recreation planning and facilities manager, said a heritage report on the building was being compiled by a consultant. “Once we’ve got a draft back we’ll liaise with Heritage New Zealand, and have a look at the options.”One can’t draw any conclusions as any decision on what might be done with it would have to wait until the report was c...

WINGS FOR SOFTER AIRCRAFT PURRS

41 weeks ago
The unique wing features of owls that make their flight silent could hold the key to making aircraft and wind turbines quieter, suggests new research. A team of researchers from Japan and China studied the serrations in the leading edge of owls’ wings, gaining new insight into how they work to make the birds’ flight silent. The results, published in the journal Bioinspiration and Biomimetics, pointed towards potential mechanisms for noise suppression in wind turbines, aircraft, multi-rotor drones and other machines. “Owls are known for silent flight, owing to their unique wing features, which are ...

SAUDI-BASED NRI TO HELP TALENTED STUDENTS

41 weeks ago
A Saudi Arabia-based NRI has joined hands with Super 30, a free coaching centre which helps children from poor families reach the prestigious IIT engineering institutes, to help talented youth from the minority community prepare for the IIT and other technical education courses. Obaidur Rahman, a businessman who is also chairman of the Bihar Foundation in Saudi Arabia, has formed an organisation called Rahman 30, which will select 30 talented students from the minority community through screening tests. These students will be provided free coaching by Super 30 founder director Anand Kumar. “The main objective is to ...

ZUCKERBERG UNVEILS FB’S NEW MISSION

42 weeks ago
Facebook’s new mission is to give the people the power to build community and bring the world closer together, the social network’s CEO Mark Zuckerberg has said. Zuckerberg unveiled Facebook’s updated purpose on Thursday at the social network’s first Community Summit, a gathering in Chicago of leaders from 120 different Facebook Groups, Forbes.com reported. Facebook’s earlier stated mission was “to make the world more open and connected”. Facebook’s new mission does not mean that the company is shifting away from connecting friends and family, but rather that it is br...

NASA DETECTS DROP IN WORLD’S FOREST FIRES

42 weeks ago
Globally, the amount of land being burned by fire is declining and this is largely due to human activities, says a study based on NASA’s satellite data. The researchers, however, found that in some parts of the world including in India, China and Brazil, the amount of land being burned by fire has increased. The total acreage burned by fires each year declined by 24 per cent between 1998 and 2015, showed the findings published in the journal Science. “Climate change has increased fire risk in many regions, but satellite burned area data show that human activity has effectively counterbalanced tha...

MELTING ARCTIC ICE RAISING SEA LEVELS

43 weeks ago
Climate change is warming the Arctic more than twice as fast as anywhere else on the planet. One of the most serious consequences is sea level rise, which threatens nations from Bangladesh to the U.S. But exactly how does melting Arctic ice contribute to sea level rise? Seas are now rising an average of 3.2 millimeters per year globally, and are predicted to climb a total of 0.2 to 2.0 meters by 2100. In the Arctic, the Greenland Ice Sheet poses the greatest risk for ocean levels because melting land ice is the main cause of rising seas—and “most of the Arctic’s land ice is locked up in Greenland,”...

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

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...
