Researchers have developed stretchable fuel cells that extract energy from sweat and are capable of powering electronics, such as LEDs and Bluetooth radios. In a paper, published in the journal Energy & Environmental Science, the researchers described how they connected the biofuel cells to a custom-made circuit board and demonstrated that the device was able to power an LED while a person wearing it exercised on a stationary bike. The biofuel cell that the Engineers from the University of California San Diego in the US developed can stretch and flex, conforming to the human body.  The research led by Prof...

In a bid to bring the augmented reality (AR) experience closer to Android users, Google has released a new software development kit (SDK) called ARCore. The platform, which is now available for developers to experiment with, will render augmented reality capabilities to existing and future Android phones, Google said in a statement late on Tuesday. The company built on the fundamental technologies used in Tango, another AR platform by Google, but ARCore is scalable across the Android ecosystem as it doesn’t require any additional hardware. The new AR platform has been rolled out to Google Pixel and Sam...

NASA’s Mars 2020 rover mission, which aims to look for signs of past life on the Red Planet, will use smart X-ray techniques originally developed to find the oldest life on Earth, according to a mission scientist. “Previous missions to Mars have used a relatively broad brush - analysing average chemistry over roughly the size of a postage stamp - to ‘follow the water’ and seek ancient habitable environments,” said the mission’s Deputy Project Scientist Ken Williford.  “Mars 2020 takes the next natural step in its direct search for evidence of ancient microbial life, fo...

A large near-Earth asteroid will pass safely by our planet on September 1, at a distance of about seven million kilometres, NASA has said. Asteroid Florence -- named in honour of Florence Nightingale (1820-1910), the founder of modern nursing -- is about 4.4 kilometres in size, according to measurements from NASA’s Spitzer Space Telescope and the asteroids and comets hunting NEOWISE mission.  “While many known asteroids have passed by closer to Earth than Florence will on September 1, all of those were estimated to be smaller,” said Paul Chodas, Manager of NASA’s Center for Near-Earth O...

Indian seismologist Arun Bapathas cautioned that in view of the large magnitude earthquake predicted in the Himalayan region, it is time to act now, and one better listens to him! The a day before the recent devastating earthquake struck China on August 8, killing close to 40 people and forcing the evacuation of thousands more, Bapat had written that this is going to happen “I daily visit the website of the Indian Meteorological Department (IMD) for various geological, meteorological, ionospheric and seismic parameters,” Bapat, a former chief of earthquake research at the Central Water and Power Researc...

Hewlett Packard Enterprise (HPE) said last week that it will launch a supercomputer into space on the SpaceX Dragon spacecraft next week, as part of a joint experiment with the US space agency NASA. The system, called the Spaceborne Computer, is designed to last for a year, which the company said is roughly the amount of time it will take to travel to Mars. “A mission to Mars will require sophisticated on-board computing resources that are capable of extended periods of uptime,” Alain Andreoil, senior vice president and general manager at HPE’s data centre infrastructure group, wrote in a blog post. “To meet these requirements, we need to improve t...

To picture what NASA is working on, one can imagine a rocket exiting Earth’s atmosphere. Its nose cone opens and what comes out is a flying carpet. The carpet, folded and rolled into a cylinder is just 3 feet in diameter and 5 feet long. After leaving the launch vehicle, it unfurls into its full expanse: 2/3rd the size of a football field and only 1 inch thick. Now one can imagine 2,500 of these spaceborne magic carpets flying together thus creating a sheet covering an area of 3.5 square miles (nine square kilometres) in the Earth’s orbit. This area is as wide as 1,670 whilst maintaining a thickness of only 1 inch.

After conducting a cosmic inventory of sorts to calculate and categorise stellar-remnant black holes, astronomers have determined that the Milky Way is home to about 100 million of the enigmatic, dark objects   far more than expected. “We think we’ve shown that there are as many as 100 million black holes in our galaxy,” said James Bullock, Professor at University of California, Irvine (UCI), and co-author of a research paper on the subject published in the journal Monthly Notices of the Royal Astronomical Society. The university’s celestial census began more than a year and a half ago, shortl...

India and Bangladesh last week decided to set up a joint working group within 60 days for the conservation of elephants and manage their movement through corridors in their adjoining border areas, an official said. The working group will develop protocols and standard operating procedures in the matter. The decision was taken at the second India-Bangladesh Dialogue on Trans-Boundary Conservation of Elephants, attended by wildlife officials from both countries here in Meghalaya.  Bangladesh Chief Conservator of Forests Md. Shafiul Alan Chowdhury led an 11-member delegation from his country. India’s...

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

29 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

30 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...
