Astronomers chart most accurate map of galaxies in our region of universe

Astronomers chart most accurate map of galaxies in our region of universeSydney, April 3 : An international team of astronomers has completed the most accurate map of hundreds of thousands of galaxies in our region of the universe.

According to a report by ABC News, the map, charted by Australian, British and American astronomers at the Anglo Australian Observatory in Coonabarabran, New South Wales, shows where galaxies are, in respect to each other, and to our own.

Astronauts need more intense workouts to maintain muscle fitness in space

Astronauts need more intense workouts to maintain muscle fitness in spaceWashington, April 3: A new study has suggested that astronauts need to modify their workouts to avoid extensive muscle loss during missions onboard the International Space Station (ISS).

The research, sponsored by NASA, was conducted at Ball State University’s Human Performance Laboratory (HPL), US.

It suggests that changes are needed to optimize the inflight exercise regimen for astronauts to improve their muscle performance while in space for extended stays.

Summers in Arctic may be ice-free in as few as 30 years

Summers in Arctic may be ice-free in as few as 30 yearsWashington, April 3: A new analysis of computer models has forecasted that summers in the Arctic may be ice-free in as few as 30 years.

“The Arctic is changing faster than anticipated,” said James Overland, an oceanographer at NOAA’s Pacific Marine Environmental Laboratory and co-author of the study.

“It’s a combination of natural variability, along with warmer air and sea conditions caused by increased greenhouse gases,” he added.

Maths algorithm may address problem of population relocation

Maths algorithm may address problem of population relocation Washington, April 2 : An international team of scientists has devised a mathematical algorithm to address the problem of population relocation.

The team comprised of decision scientist Sajjad Zahir at the University of Lethbridge, Alberta, Canada, and colleagues Ruhul Sarker of the University of New South Wales, Canberra, Australia and Ziaul Al-Mahmud of Lethbridge Community Network.

Tapping industrial waste heat could reduce fossil fuel demands

Tapping industrial waste heat could reduce fossil fuel demands Washington, April 2 : A team of scientists has determined that tapping industrial waste heat could reduce fossil fuel demands in the short term and improve efficiency of countless manufacturing processes.

The scientists, Lihua Zhang and Tomohiro Akiyama of Hokkaido University, Sapporo, Japan, explain that heat waste from industrial processes, such as combustion and electricity generation is sometimes of low energy and diffuse.

Capturing this low-quality heat for re-use elsewhere on an industrial plant is usually not practical.
