NEW LITHIUM-AIR BATTERY SURVIVES HUNDREDS OF CYCLES
Batteries supply electrons by undergoing reversible chemical reactions. That has meant that all the reactants have to be inside the battery, which adds to its weight and volume. Lithium-air batteries could potentially change that situation. At one electrode, they have pure lithium metal rather than a lithium-containing chemical. At the other, the lithium reacts with oxygen in the air. When the battery is charged, this reaction is reversed, and the oxygen is returned to our atmosphere.

The i8 Roadster model, due to hit showrooms in May, is equipped with what BMW calls its fourth-generation electric drive technology. Advances in battery raw materials and chemistry has increased its range by 40 percent over the previous version, BMW said. Source: reuters.com
SPACEX LAUNCH LAST YEAR PUNCHED HUGE, TEMPORARY HOLE IN THE IONOSPHERE
Contrary to popular belief, most of the time when a rocket launches, it does not go straight up into outer space. Rather, shortly after launch, most rockets will begin to pitch over into the downrange direction, limiting gravity drag and stress on the vehicle. Often, by 80 or 100km, a rocket is traveling nearly parallel to the Earth’s surface before releasing its payload into orbit.

Some people preferred to give the carcass a cryptozoological origin story, due to the animal’s likeness to a legendary creature called Altamaha-ha, which is Georgia’s riff on the Loch Ness monster. The resemblance to the cryptid has resulted in experts cautioning that the whole thing could have been a hoax. Source: vice.com
NORTH INDIAN FOOD OR SOUTH INDIAN FOOD ,DEEP LEARNING KNOWS IT ALL!
When you travel India from Kashmir to Kanyakumari you’ll experience different culture,different religion but what important aspect for me is the varieties of food available in different parts of my country from Samosa or Khaman Dhokla in North India to Idli or Dosa in South India,this is some among many varieties of food you can have or rather enjoy tasting in India.

Don’t follow the TensorFlow docs since they explain how to setup a docker image and compile TF serving that takes forever. We can do much better. Some guy made a docker image with everything already compile on it, so we are going to use that one. Source: towardsdatascience.com
ANTI-ANTI-COMMUNISM
A 2009 poll in eight east European countries asked if the economic situation for ordinary people was ‘better, worse or about the same as it was under communism’. The results stunned observers: 72per cent of Hungarians, and 62per cent of both Ukrainians and Bulgarians believed that most people were worse off after 1989. In no country did more than 47per cent of those surveyed agree that their lives improved after the advent of free markets.

You really can extract clean drinking water right from the air, even in the driest of deserts, MIT researchers have found. They’ve demonstrated a real-world version of a water-harvesting system based on metal organic frameworks, or MOFs, that they first described last year. Source: mit.edu
THE SURPRISING RELATIVISM OF THE BRAIN’S GPS
Physics grappled with the question of whether space is absolute or relative for centuries, before deciding in favor of relativity. But, it is only in recent years that the brain sciences have begun to discuss a parallel set of questions. For many years now, absolute space has ruled neuroscience. In the visual system, for example, it has long been assumed that there are two channels of information flow.4 The first is the “what” channel, carrying information about the identity of objects that an animal sees. The second is the “where” channel, containing information about the absolute position of these objects.

According to this research, a dim red dwarf star, along with its even dimmer brown dwarf companion—a kind of bloated gas giant that failed to ignite into a full-blown star—came to within 0.8 light-years of our Sun (4.7 trillion miles, or 50,600 AU, where 1 AU is the average distance of the Earth to the Sun), and possibly as close as 0.6 light-years (3.53 trillion miles, or 37,900 AU). That’s a close shave, at least by cosmological standards. By comparison, MU69, a Kuiper Belt object that will be visited by the New Horizons spacecraft on New Year’s Day 2019, is about 43 AU from the Sun.
