Scientists working with a NASA probe that investigates how the Sun’s and Earth’s magnetic fields connect and disconnect have uncovered a new type of magnetic event in our near-Earth environment.
Launched in 2015, the Magnetospheric Multiscale, or MMS, consists of four identical spacecraft that orbit around Earth through the dynamic magnetic system surrounding our planet to study a little-understood phenomenon called magnetic reconnection.
Magnetic reconnection is a phenomenon unique to plasma, that is, the mix of positively and negatively charged particles that make up the stars, fill space and account for an estimated 99 per cent of the observable universe.
The new discovery, detailed in the journal Nature, found reconnection where it has never been seen before — in turbulent plasma. For the study the scientists used an innovative technique to squeeze extra information out of the data.
“In the plasma universe, there are two important phenomena: magnetic reconnection and turbulence,” said Tai Phan, a senior fellow at the University of California, Berkeley, and lead author on the paper.
“This discovery bridges these two processes,” Phan said.
The finding of reconnection in turbulence has implications, for example, for studies on the Sun.
It may help scientists understand the role magnetic reconnection plays in heating the inexplicably hot solar corona — the Sun’s outer atmosphere — and accelerating the supersonic solar wind.
Magnetic reconnection is one of the most important processes in the space around Earth.
This fundamental process dissipates magnetic energy and propels charged particles, both of which contribute to a dynamic space weather system that scientists want to better understand, and even someday predict.
Reconnection occurs when crossed magnetic field lines snap, explosively flinging away nearby particles at high speeds.
Magnetic reconnection has been observed innumerable times in the magnetosphere — the magnetic environment around Earth — but usually under calm conditions.
The new event occurred in a region called the magnetosheath, just outside the outer boundary of the magnetosphere, where the solar wind is extremely turbulent.
Previously, scientists did not know if reconnection could even occur there, as the plasma is highly chaotic in that region. MMS found it does. (IANS)
Union Finance Minister Nirmala Sitharaman on Saturday asked the Directorate of Revenue Intelligence (DRI) to prevent dumping of toxic wastes in India. Speaking at an event to celebrate DRI's 64th foundation day, Sitharaman lauded DRI's compact strength of about 800 officers for their relentless efforts despite the imminent risks. The Finance Minister stated that the officers may be keeping a low profile, but they are acting like the frontline defence forces, doing spectacular work in safeguarding the economic frontiers of the country. "The recent smuggling attempts of huge quantities of narcotics, gold, red sanders, ivory, cigarettes etc. unearthed by DRI were appreciated by the Finance Minister," the Ministry of Finance said in a statement.
"Sitharaman said that the message through such enforcement actions should be such that these acts of brazen attempts at smuggling are nipped in the bud," the statement added. The Finance Minister also said that better coordination among the law enforcement and intelligence gathering agencies and sharing of actionable intelligence are the way forward in protecting the frontiers of the country more efficiently. "Sitharaman also asked the DRI to focus on interdicting dual use technology items as well as preventing the dumping of toxic wastes in our country," the statement said. (IANS/ MBI)

Tech giant Amazon has expanded the sound detection capabilities of Alexa along with more features. Alexa can now identify the sounds of running water and appliances beeping, reports Android Central. This means users can set up an Alexa routine to notify themselves when the washer beeps to indicate that laundry is finished, the report said.
When Alexa detects that the faucet has been left open, it will send users a notification as well so they can take appropriate action, it added. Amazon previously said at its event in September that it would add the ability to programme Alexa to recognise custom sounds, but that feature has yet to arrive. Having said that, the two new sound detection capabilities not only help users save energy, but they also make it easier to avoid paying for unnecessary charges on your home utilities, the report said.
The retail giant has also announced ultrasound motion detection, which will allow you to set up "Occupancy Routines" on additional Echo devices. This feature allows your smart speaker to detect nearby motion and initiate a routine, such as turning on the lights. It is compatible with many of the best Alexa speakers including the 4th-gen Echo, Echo Dot and Echo Dot with Clock. (IANS/ MBI)
