The best from the science journals: Story of sleep and sea stars

Here are some of the most interesting research to have appeared in top science journals last week

Rock-a-bye baby

Published in Current Biology

Have trouble sleeping? Buy a rocking bed. Two studies published last week have found out that continuous rocking helps in falling asleep faster and sleeping more soundly. In the first study, 18 adults underwent a sleep monitoring programme in a lab and the researchers noted that the group that slept on a gentle rocking bed had more non-REM deep sleep. The second study carried on mice was able to point out that the rocking promoted sleep through a rhythmic stimulation of the vestibular system(the region in the inner ear that maintains balance).

Similar to the growing water jelly balls you have at home, MIT engineers have designed a soft tablet that can grow in your stomach and stay there for about a month. But why? The researchers say that this hydrogel device can be used to closely study the digestive system. It can even help monitor medication-taking patterns, track cancers or ulcers in the gastrointestinal tract

 

King-sized in Kuiper

Published in Nature Astronomy

The Kuiper Belt, the doughnut-shaped ring of icy objects beyond Neptune, has always fascinated astronomers. Believed to be leftovers of the early Solar System, objects floating in this belt help to understand the formation and evolution of our Solar System. Now astronomers have discovered a Kuiper belt object with a radius of about 1.3 km, the largest discovered so far. They hope to decipher more about the growth phase of objects and planets in the outer Solar System.

What happens when scientists awaken the child in them? They create play dough with a twist. A group of researchers from Northwestern University, USA has turned graphene oxide(GO) into a soft dough that can be shaped into 3D structures. The GO dough makes storage and transport of graphene oxide easier. It also has enhanced the mechanical properties of graphene and can be used to make electrocatalysts.

See you, sea stars

Published in Science Advances

After affecting corals and crustaceans, warming oceans have now led to a massive decline in sea star population. Researchers have pointed out that infectious viral disease and increasing sea surface temperatures are the

main reasons. Divers noted that between 2013 and 2017, the population collapsed and they were unable to find the sea stars in areas where they once reported an abundance of the species.

Best tech of 2018 – Part 2

Best tech of 2018,Samsung Q8C OLED TV,Nokia 8.1

Samsung Q8C OLED TV

The Q8C maintained its superiority all through the year. Bezel-less design, stunning colour and an aggressive price kept the rest of the competition at bay. Of course if you’ve got the money then the 88-inch version of this, the Q9F at Rs 24,99,900, is the absolute best you can buy now.

Nokia 8.1

This is the year and this is the phone that made the real Nokia stand up and be counted. Elegant and understated, stunning, true android experience, always first to get updates, great camera and a very aggressive price point. Nokia ensured customers’ experience was more important than gimmicks.

Google Home Hub

The Hub is Google adding a 7-inch display to its Home devices that lets users not just hear a response, but also see it. The screen personalises itself to every home member, shows YouTube videos, Google map info, and can control any smart home device and IoT product. The only thing missing is a camera for video calls.

Garmin Fenix 5X Plus

In a world of fitness bands and smartwatches, this is the ultimate beast. Made of titanium, this is an auto sensing multi-sport GPS watch with heart rate technology, run maps on display, a pulse blood oxygen saturation levels sensor, sapphire lens glass and 18-day battery life in smartwatch mode.

Devialet – Phantom Reactor 900

This company changed how people thought of a bluetooth speaker with its Phantom series. Now a huge step further, the Reactor is super small and yet insanely powerful. It can belt out a true 900 watts of undistorted sound including full sub woofer output and do it on Bluetooth, Wi-Fi, optical or analog.

Samsung Galaxy A9

They all called it gimmicky. Why would you need four cameras at the back of a phone? Samsung answered with a big bang. Each camera at the back has a specific function and the phone is intelligent enough to know what to use and when. Eventually the Samsung A9 is the best optics phone under 40K.

XIAOMI MI TV 4 PRO 55 INCH

This was the most exciting TV launched in the country and if it’s Xiaomi, they have to do it different and also make all other TVs look strangely over-priced. A 55-inch display, world’s thinnest LED at 4.9 mm, near bezel less, HDR 10, integrated Mi Sound Bar with 10 speakers and a price under 40K.

Vivo Nex

Vivo may well be the most innovative phone company this year. They came out with the world’s first in-display finger print scanner. They came up with a pop out camera that ensured that the display has no notch. Now everyone wants to do the same. The Nex was the first to do both together.

Oppo R17 Pro

Round up every big innovation of the year like an in-display fingerprint scanner, water drop notch, three cameras at the back, add a stunning design, then add super fast charging with dual batteries. What you get is a phone that makes your eyes and jaw open wide.

Corning Gorilla Glass 6

This is Corning taking things to its logical conclusion where your phone screen can withstand falls and doesn’t scratch. Nothing more heartbreaking than when your phone screen breaks, and Corning with its 6th generation tech is ensuring in the future, it won’t.

Panasonic OLED TV

With the TH-65FZ1000D they have an absolute winner. Excellent colour reproduction, thin frame, multi HDR support and an array of 12 speakers in its blade audio set up, this TV is the real 4K deal!

Mediatek Helio P 70

This is the year that Mediatek threw down the gauntlet and decided that people should buy a phone by asking for the processor inside by name. With some serious horse power, stunning artificial intelligence, better battery optimisation and amazing optical tricks, the P 70 will be the chip of choice on most mid-priced phones from here on.

For every one product I’ve highlighted here, I had to leave out at least five great ones. That summarises how good tech was in 2018. Watch out for 2019 though, as you haven’t seen anything yet…
