Wendelstein 7-X Nuclear Fusion Machine Receives Positive Feedback from Physicists

Wendelstein 7-X Nuclear Fusion machine developed by researchers in Germany has received support from scientific community as the reactors works as expected. The Wendelstein 7-X Nuclear Fusion reactor uses very complex stellerator system to operate. Nuclear fusion generates high amount of energy and scientists have warned about difficulty to control this high amount of energy. Nuclear stellerator concept was showcased by Max Planck Institute for Plasma Physics researchers last year.

Reykjavik Council switches off city lights to provide clear view of Northern Lights to residents

Reykjavik Council switches off city lights to provide clear view of Northern Lights to residents

On Wednesday night, Reykjavik council switched off the lights in the city centre and many other districts from 22:00 local time. Main aim behind the move was to lessen the light pollution so that the capital's residents are able to enjoy the Aurora Borealis, one of the most impressive views of the sky.

Some States could rethinkLED streetlights after AMA links them with health issues

Some States could rethinkLED streetlights after AMA links them with health issues

Concerns have been raised over the past few years about negative impacts of high-intensity LED streetlights. In June, the American Medical Association report has added credence to these concerns.

In the report, the high-intensity LED streetlights in Seattle, Los Angeles, New York, Houston, and San Francisco and in many other places have been linked with disturbed sleep, increased risk of health conditions, like cancer and cardiovascular disease.

Oldest Indigo-dyed fabric in world discovered

Oldest Indigo-dyed fabric in world discovered

During a 2009 excavation of HuacaPrieta, a Peruvian ceremonial mound, archaeologists have discovered a 6,200-year-old piece of indigo dyed fabric. Upon testing the samples, researchers came to know that the cotton scraps were at least 1,800 years older than the next-oldest instances of indigo dye use.

Study’s lead researcher Jeffrey Splitstoser said that the cotton used in that time’s fabric is the same that is grown today and is known as Egyptian cotton. The researchers have shared that the cloth scarps were found in-between layers of a ramp that led up to the temple.

Two-thirds of methane coming from just 25 locations out of over 250 newfound sources of methane hot spots

Two-thirds of methane coming from just 25 locations out of over 250 newfound sources of methane hot spots

Over 250 sources of a methane hot spot have been discovered by researchers over the Four Corners region of Arizona, Colorado, New Mexico and Utah. The sources include gas wells, storage tanks, pipelines and processing plants.

It is considered that extra methane is the result of leaks during natural gas production. There were very few sources that were from natural seeps and one was found to be from a coal mine. As much as two-thirds of the ejection was from around 25 locations.

1991 Mt. Pinatubo volcanic eruption behind depressing global sea levels for two decades

Scientists were baffled as earth’s mean sea level has been rising at a steady 3 millimeters per year since 1992. Now, after more than two decades they have been able to solve the mystery, which is the Mt. Pinatubo volcanic eruption of 1991.

Possibility of finding new particle bleak: LHC scientists

Possibility of finding new particle bleak: LHC scientists

Scientists working on the Large Hadron Collider have cleared at the International Conference on High Energy Physics (ICHEP) that the discovery of new particle might be many years away.

The scientists were quite disappointed, as there was a lot of excitement when they started LHC to collect data as it showed a bump, but in the latest results they did not see any signs of a bump. David Charlton of Birmingham University said that the two separate LHC detectors, Atlas and CMS, have picked up matching bumps. But it could be considered only as a pure coincidence.

Novel technology that directly uses sun’s energy could lessen climate change

Novel technology that directly uses sun’s energy could lessen climate change

If this experimental solar-powered technology makes a successful transition from the laboratory to industrials-scale use, it can prove quite beneficial in reducing the effect of climate change.

Navy should not be allowed to use LFA sonar systems: Ninth Circuit Court of Appeals

Navy should not be allowed to use LFA sonar systems: Ninth Circuit Court of Appeals

The Ninth Circuit Court of Appeals in California has said that low-frequency active (LFA) sonar systems used in world’s oceans violates the Marine Mammal Protection Act. Also, they have a negative impact on dolphins, seals, whales and walruses, as they are dependent on underwater sound for navigation.

LFA are used in areas covering 70% of the world’s oceans. The court has ruled out that it would not allow the Navy to use the LFA sonar systems to detect the presence of submarines. Experts said that the navy sonar systems could generate sound waves as high as 235 decibels.

Speculations high on new particle discovery with LHC

Speculations high on new particle discovery with LHC

Researchers at CERN are preparing to unveil the data from the Large Hadron Collider (LHC), after hiatus of three years of the confirmation of the existence of the Higgs Boson. The researchers said that the probability of finding something new is highest.

Scientists have been sifting through the debris from the smash-up of two beams of protons, so as to have hint of previously undiscovered particles. Last year, scientists were able to detect more photon particles than expected.
