Scientists have long questioned why the bursts of hot gas from the sun do not cool down as fast as expected and have now used a supercomputer to find out.

When the solar wind hits the Earth, it is almost 10 times hotter than expected, with a temperature of about 100,000 to 200,000 degrees Celsius. The outer atmosphere of the sun, where the solar wind originates, is typically a million degrees Celsius.


Using these simulations, the team, led by University College London (UCL) researchers, deduced that the solar wind stays hot for longer because of small-scale magnetic reconnection that forms in the turbulence of the solar wind.

This phenomenon occurs when two opposing magnetic field lines break and reconnect with each other, releasing huge amounts of energy. This is the same process that triggers large flares erupting from the sun’s outer atmosphere.

“Magnetic reconnection occurs almost spontaneously and all the time in the turbulent solar wind. This type of reconnection typically occurs across an area of several hundred kilometers — which is really tiny compared to the vast dimensions of space. Using the power of supercomputers, we have been able to approach this problem like never before. The magnetic reconnection events we observe in the simulation are so complicated and asymmetric, we are continuing our analysis of these events,” said lead author Jefferson Agudelo of UCL.

To confirm their predictions, the team will compare their data with that collected by the European Space Agency’s (ESA) latest flagship mission, Solar Orbiter.

The Solar Orbiter is designed to find the origins and causes of the solar wind and study the workings of our sun.

“This is an incredibly exciting time to combine huge plasma simulations with the latest Solar Orbiter observations. Our understanding of reconnection and turbulence could take a major leap forward by combining our simulations with the new data from the Solar Orbiter,” Agudelo explained. (IANS/KB)

Dia Mirza champions sustainable fashion

Actor and environmental activist, Dia Mirza, who is also the National Goodwill Ambassador for the United Nations Environment Program (UNEP) was showstopper for Indian designers Abraham & Thakore at the recently held LFW X FDCI event. The designer duo who are pioneers of slow fashion and sustainability in the Indian fashion landscape showcased a timeless sustainable collection.

IANSlife spoke with Mirza on sustainable choices when it comes to fashion.

Read Excerpts:

Q: Did you enjoy the on-ground fashion event and the energy that came with the physical show and appearance?
A: Yes absolutely. It was just so refreshing and wonderful to finally be back from a virtual audience. Last year we did a digital show and the energy was just not there, this is an interactive experience and we draw so much from real people.

Q: The outfit that was chosen for you, how did it complement your style?
A: It's a garment that I think involves and is reflective of what I stand for, I deeply care about sustainability and I love the fact that the garment has been made with repurposed material, used and created with a hundred per cent post-consumer bottles, and made by the waste generated from the pieces of fabric that we discard while creating other garments. So it was a very special garment that really and truly celebrated repurposing and reusing and upcycling.

Dia Mirza is an Indian model, actress, producer, and social worker who predominantly works in Hindi films. Mirza won the title of Miss Asia Pacific International in 2000. IANSlife spoke with Mirza on sustainable choices when it comes to fashion. | Wikimedia Commons

Delhi to get new QR-based driving livenses and registration certificates.

In a step towards digitisation of the system, Delhi Transport Department will soon issue QR based Smart cards for driving licenses (DLs) and registration certificates (RCs).

As per a statement, the new driving licence will have an advanced microchip with features like Quick Response (QR) code and Near Field Communication (NFC). The new RC will have the owner's name printed on the front while the microchip and the QR code would be embedded at the back of the card.

The cards earlier had embedded chips, but chip reader machines were not available in the required quantity with both the Delhi Traffic Police and the Enforcement Wing of the Transport Department. Moreover, chips were designed and implemented by the states concerned, which resulted in difficulties in reading the chip and retrieving information, especially in case of defaulters.

"Now with the QR based smart card, this issue is resolved. This will enable unification in linking and validating one's information to smart cards with Sarathi and Vahan, the two web-based databases of all driving licenses and vehicle registrations," the release added.

The QR is also being implemented nationwide, the QR code reader is easily procurable and will do away with the requirement of any manual intervention altogether. The new cards will also allow two specific materials for their card manufacturing -- PolyVinyl Chloride or PVC, or PolyCarbonate which is slightly more expensive but more durable. (Card Size - 85.6mm x 54.02 mm; Thickness minimum 0.7 mm)

An October 2018 notification of the Ministry of Road Transport and Highways (MoRTH) had made changes to the Driving License and Registration Certificate. The new Smart card based DL and RC, will have chip based/ QR code based recognition system. At the same time, documents such as driving license or registration certificates in electronic formats on DigiLockers and mParivahan were also made valid in place of physical documents and treated at par with original documents.

The QR code also has an added advantage of acting as a safety feature on the smart card. The department will be able to retain records and penalties of the DL holder for up to 10 years on the VAHAN database as soon as a driver/ owner's Smart card is confiscated. The new DLs will also help the government in maintaining records of differently-abled drivers, any modifications made to the vehicles, emission standards and the person's declaration to donate organs.

In this handout photo provided by Sotheby's Auction House, the auction for Banksy's "Love is the Bin" takes place in London, Oct. 14, 2021

LONDON — A work by British street artist Banksy that sensationally shredded itself just after it sold at auction three years ago fetched almost 18.6 million pounds ($25.4 million) on Thursday — a record for the artist, and close to 20 times its pre-shredded price.

"Love is in the Bin" was offered by Sotheby's in London, with a presale estimate of 4 million pounds to 6 million pounds ($5.5 million to $8.2 million).
