Washington: A group of Indian students is part of 80 teams that will participate in the US space agency’s “Human Exploration Rover Challenge” to help NASA realise its goals for future exploration to Mars and beyond.
Nearly 80 teams from the US, India, Italy, Germany, Mexico, Colombia, Russia and Puerto Rico will compete in NASA’s annual challenge to be held at the US Space and Rocket Centre in Huntsville, Alabama on April 8 and 9.
The rover challenge requires student teams to design, construct, test and race human-powered rovers through an obstacle course that simulates the terrain potentially found on distant planets, asteroids or moons.
Teams race to finish the three-quarter-mile-long obstacle course in the fastest time, vying for prizes in various divisions, NASA said in a statement.
This year’s event incorporates two new and important changes. Teams are required to design and fabricate their own wheels.
Any component contacting the course surface for traction and mobility, including, but not limited to wheels, tracks, treads or belts cannot be purchased or considered an off-the-shelf product.
The second new feature is an optional “Sample Return challenge”.
Teams competing in this separate competition will collect four samples — liquid, small pebbles, large rocks and soil samples — using a mechanical arm or grabber they design and build.
The event will conclude with a ceremony at the Davidson Centre for Space Exploration in Huntsville where the awards will be presented for best design, rookie team, pit crew award and other accomplishments.
Inspired by the lunar roving vehicles of the Apollo moon missions, the competition challenges students to solve engineering problems, while highlighting NASA’s commitment to inspiring new generations of scientists, engineers and explorers. (IANS)

When popular smartphone brands like Xiaomi and realme entered the laptop market in India last year, they were expected to shake the existing giants, specifically under the Rs 50,000 category. However, chip shortage and supply crunch have somewhat dented their plans to make a significant mark to date. According to industry experts, the issue with smartphone makers entering the laptop category is two-fold. The first one is a massive supply crunch in the laptop component market and only big brands are able to get volume and supplies.
The other factor is that the traditional players are very strong in the consumer laptop market. Top 3 players control more than 70 per cent of the market and strong portfolio, distribution, and channel reach as well as brand marketing has helped them massively. "New brands can surely make a dent in the consumer laptop market but are challenged by supply issues right now. Watch out for them in 2022 as and when supply situation eases up," Navkendar Singh, Research Director, Client Devices & IPDS, IDC India told IANS.
Dominated by HP Inc, Lenovo and Dell, the traditional PC market (inclusive of desktops, notebooks, and workstations) in India continued to be robust as the shipments grew by 50.5 per cent year-over-year (YoY) in the second quarter (Q2), according to IDC. Notebook PCs continue to hold more than three-fourth share in the overall category and grew 49.9 per cent YoY in 2Q21, reporting a fourth consecutive quarter with over 2 million units. Desktops also indicated a recovery as shipments grew 52.3 per cent YoY after recording the lowest shipments of the decade in 2Q20.
According to Prabhu Ram, Head, Industry Intelligence Group, CMR, driven by the pandemic and the associated accelerated pivot to remote work, learn and unwind culture, PCs have been witnessing heightened demand. "Despite the current supply chain constraints, PCs are here to stay in the new never normal. In the run-up to the festive season, established PC market leaders will continue to leverage their brand salience and gain market share," Ram told IANS.

"On the other hand, there is a niche market for those new market entrants that are able to differentiate themselves from the competition in terms of features and value. "Alongside, they would need to back it with strong brand messaging to create awareness and recall amongst the target consumers," Ram added.
HP maintained its lead in the India PC market with a 33.6 per cent share as its shipments grew 54.2 per cent annually. Dell Technologies continued to hold the second position with a 22.1 per cent share and an impressive 86.1 per cent YoY growth in 2Q21. Lenovo maintained the third position with a share of 17.8 per cent in 2Q21.
Arvind Suraj, Research Fellow, Jawaharlal Nehru University (JNU), said that there is always a trust issue with new brands. "You won't buy a laptop in 6 or 7 months just like smartphones. In this case, we often go for existing players. Brands like Lenovo, HP, ASUS and Acer have already gained our trust," he said. (IANS/ MBI)

A drug used to treat agitation in people with dementia is no more effective than a placebo, and might even increase mortality, according to a new study published in The Lancet. The research, led by researchers at the University of Plymouth, showed that antidepressant mirtazapine offered no improvement in agitation for people with dementia -- and was possibly more likely to be associated with mortality than no intervention at all.
Agitation is a common symptom of dementia, characterized by inappropriate verbal, vocal or motor activity, and often involves physical and verbal aggression. Non-drug patient-centered care is the first intervention that should be offered but, when this doesn't work, clinicians may move to a drug-based alternative.

Antipsychotics have proven to increase death rates in those with dementia, along with other poor outcomes, and so mirtazapine has been routinely prescribed. This study was designed to add to the evidence base around its effectiveness. The study recruited 204 people with probable or possible Alzheimer's disease from 20 sites around the UK, allocating half to mirtazapine and half to placebo.
The trial was double-blind; meaning that neither the researcher nor the study participants knew what they were taking. The results showed that there was no less agitation after 12 weeks in the mirtazapine group than in the control group. There were also more deaths in the mirtazapine group (seven) by week 16 than in the control group (only one), with analysis suggesting this was of marginal statistical significance.
"Dementia affects 46 million people worldwide -- a figure set to double over the next 20 years. Poor life quality is driven by problems like agitation and we need to find ways to help those affected," said lead researcher Professor Sube Banerjee, Executive Dean of the Faculty of Health at the varsity. "This study shows that a common way of managing symptoms is not helpful -- and could even be detrimental. It's really important that these results are taken into account and mirtazapine is no longer used to treat agitation in people with dementia," Banerjee added. (IANS/ MBI)

Digital beauty platform Boddess.com aims to be a disrupter in the Indian beauty market segment offering a curation of products to suit customisation and individual needs. Intime for the festive season, Chandni Goyal, Training Manager at House of Beauty and Boddess, shares a few tricks to see you through endless nights of partying:
* Have fun with colour and sparkle--Move away from blacks and browns and experiment with colours complementing your outfit. The traditional smokey eye can be given a touch of glamour with a dab of glitter eyeshadow in the inner corner of your eyes. It will make your eye make-up pop and will be just what is needed for a festive look.

* Define your eyes with wing eyeliner--Don't shy from entering the negative space and go all out to draw a bold line to define your eyes and make a statement. Start from the inner corner of the top lid--keep the line thin here, extending along the lash line, going thicker, and finishing with a thick wing towards the outer corner of the eyes.

* Don't forget the lashes--They can really make or break your entire look. Add a few generous coats of volumizing mascara and if you are a pro, apply false eyelashes for added depth.

* Glossy lips--Glossy lips are big this season. Define your lips with a nude-pink lip liner and fill in the same lip liner all over your lips. Top it up with a clear crystal gloss that gives a glass-like shine and makes your lips look fuller and plumper.

* For the cheeks--A pop of colour that imparts a flushed, radiant glow will round out your look beautifully. This can be achieved with a cream blush, on the apples of your cheeks, and a layer of highlighter that melts into the skin on your cheekbone. Pinks, peaches and corals are the colours this season.
