Tesla and other car companies are selling a record number of electric vehicles (EVs). But even at
souped-up “supercharger” stations, the cars still require more than 1 hour to top off their
batteries. A new advance may change that.
One strategy for boosting battery charging speeds has been to raise the battery temperature
during charging, which accelerates the chemical reactions inside the battery. But keeping
batteries at high temperatures can cause components to break down quickly.
Now, researchers report they can prevent this breakdown, and allow fast charging, if the heat
is added just for short periods. By heating up a charging device to 60°C for just 10 minutes,
they were able to speed the incorporation of lithium ions into layers of graphite that make
up the anode (as shown in the above artist’s representation), the key step in recharging the
battery. If scaled up, this would allow them to add 320 kilometers in driving range to
conventional lithium-ion batteries, they report today in Joule. The heated batteries
were also stable, able to go through 1700 charge-discharge cycles with little degradation.

Next up, the researchers are looking to cut their charging time in half, adding enough juice
to power an EV in just 5 minutes.

Ninety-nine per cent of all freshwater ice on Earth is sitting on top of Greenland and Antarctica, and
each year, a little more of it melts into the ocean.
Normally, it would take hundreds to thousands of years for it all to melt away. But what if something
happened that caused a massive global melt overnight?
As we slept, sea levels would rise by a whopping 66 meters. Coastal cities like New York, Shanghai,
and London would drown in the apocalyptic mass flood, forcing up to 40 percent of the world's population
out of their homes.
While all this chaos ensues above-ground, something equally sinister is happening below. All that rising
saltwater will infiltrate
groundwater reserves farther inland, forcing its way into nearby freshwater aquifers.
You know, the ones that supply our drinking water, irrigation systems, and power-plant cooling systems?
All those aquifers would be destroyed. Not good.
On top of that, the ice on Greenland and Antarctica is made of freshwater, so when it melts, that's about
69 percent of the world's freshwater supply that's going straight into the oceans. This will wreak
havoc on our ocean currents and weather patterns.
Take the Gulf Stream, for example. It's a strong ocean current that brings warm air to northern Europe
and relies on dense, salty water from the Arctic in order to function. But a flood of freshwater would
dilute the current and could weaken or even stop it altogether.
Without that warm air, temperatures in northern Europe would plummet, and that could spawn a
mini ice age, according to some experts.
That's not even the worst of it. Take a look at what will happen when that last 1 percent of freshwater
ice that's not part of Greenland or Antarctica thaws. Some of that 1 percent is sitting in glaciers farther
inland.
The Himalayan glaciers specifically pose one of the largest threats because of what's trapped inside:
toxic chemicals like dichlorodiphenyltrichloroethane, or DDT. Scientists discovered that glaciers
like this can store these chemicals for decades. But as they thaw, those glaciers release the chemicals
into rivers, lakes, and groundwater reserves, poisoning each one as they go.
The rest of that 1 percent is hanging out underground, mostly in the Arctic tundra, as something
called permafrost. Permafrost is organic matter that's been frozen in the ground for two-plus years.
Now, one of the most immediate problems with thawing permafrost would be mercury poisoning.
That's right: There are an estimated 15 million gallons of mercury stored up in the Arctic permafrost.
That's almost equal to the amount of mercury everywhere else on Earth.
On top of that, the organic matter in permafrost is a tasty meal for microorganisms. After they digest it
all, they fart out two of the most potent greenhouse gases out there, carbon dioxide and methane.
Scientists estimate this could double the current levels of greenhouse gases in the atmosphere, and
potentially cause global temperatures to rise by 3.5 degrees Celsius compared to today.
That might not sound like much, but say goodbye to that mini European ice age, and even rivers
and lakes around the world. They'd evaporate from the higher temperatures and cause mass droughts
and desert-like climates. And all that extra water vapour in the atmosphere would fuel more frequent
and stronger storms, floods, and hurricanes.
So all of that newly established coastline on the eastern US would be one of the last places you'd want
to live. Instead, there would be mass migrations to Canada, Alaska, the Arctic, and even what's left
of the Antarctic.
And you're right, this is probably never going to happen. After all, there's enough ice right now to cover
the entire continent of North America in a sheet a mile thick.
So the next time you hear about record-breaking heat or ultra-powerful hurricanes, at least you know
that it could be worse. But scientists estimate that if we don't take action and global temperatures
increase by just 1 degree Celsius, the effects of climate change we already see today will be irreversible.
So yes, it could be worse, and it will be if we're not careful.

With the discovery of 20 more moons orbiting Saturn, the ringed planet has overtaken Jupiter as host to
the most moons in the Solar system. Saturn now has 82 known moons, whereas Jupiter has a paltry 79.
Announced at the International Astronomical Union's Minor Planet Centre by a team of astronomers
from the Carnegie Institute for Science led by Scott S. Sheppard, the discovery is the latest advance in
the 400-year history of our understanding of the satellites of our neighbouring planets.
As technology has improved, we have observed more and more of these tiny, distant worlds – and we
can be reasonably confident there are still plenty waiting to be discovered.

How do we even know Saturn has moons?

Although most planets of the Solar system are visible to the naked eye and have been known to humans
since antiquity, it wasn't until Galileo Galilei turned a telescope on Jupiter in 1610 that we discovered
Earth was not alone in having an orbiting companion.
Galileo saw Jupiter's four largest moons and could make out what we now know are Saturn's rings.
Decades later, with better telescopes, Christian Huygens and Giovanni Domenico Cassini observed
Saturn's moons.
It became clear that the giant planets are surrounded by multitudes of satellites, resembling smaller
versions of the Solar system.
By the middle of the 19th century, telescopes had improved enough that the first eight moons of
Saturn – including Titan, the largest – had been viewed directly.
The introduction of photographic plates, which enabled the detection of fainter objects with
long-exposure observations, helped astronomers increase their count of Saturn's moons to 14.

Closer inspections

It was a long journey (literally) to the next big improvement in our view of Saturn's moons. Many of
the smaller moons were not discovered until the Voyager fly-by missions in the 1980s and the more
recent 13-year stopover of the Cassini spacecraft in Saturn's orbit.
Until these closer visits, we knew little about the moons aside from the fact that they existed.
One of Cassini's goals was to explore Titan, which is the only moon in the Solar system with a thick,
smoggy atmosphere. Another was to take a look at Saturn's other mid-sized moons, including frozen
Enceladus, which may hold an ocean of liquid water beneath its icy crust.
Cassini also discovered much smaller moons, so-called "shepherd moons" that interact with
Saturn's rings by carving gaps and wavy patterns as they pass through a rubble of rocks and snowballs.

Bigger telescopes, more moons

These close-up observations from space advanced our understanding of individual moons that stay
near to Saturn. Recently, many more moons have been found in orbits much further from the planet.
These more distant moons could only be detected with large optical telescopes such as the Subaru
telescope at Mauna Kea in Hawaii. The telescope is equipped with sensitive cameras that can detect
some of the faint objects separated by millions of kilometres from Saturn.
To confirm that these objects are indeed associated with Saturn, astronomers have to observe them
over days or even months to reconstruct the shape and size of the moon's orbit.

Many small moons are fragments of shattered large moons

Such observations revealed a population of moons that are often described as "irregular" moons.
They are split into three distinct groups: Inuit, Gallic, and Norse. They all have large, elliptical
orbits at an angle to those of moons closer to the planet.
Each group is thought to have formed from a collision or fragmentation of a larger moon. The
Norse group consists of some of the most distant moons of Saturn, which orbit in the opposite
direction to the rotation of the planet.
This suggests they could have formed elsewhere and were later captured by the gravitational force
of Saturn.
Of the 20 new moons, 17 belong to the Norse group including the furthest known moon from the
planet. Their estimated sizes are of the order of 5km in diameter.

Have we found all the moons now?

Are we likely to find even more moons around Saturn? Absolutely.
Some of the newly discovered moons are very faint and at the limit of detection with currently
available instruments. New, bigger telescopes such as Giant Magellan Telescope will allow us to
observe even fainter objects.
In the meantime, the 20 new moons need names. Carnegie Science has invited everyone to help.The Conversation

What is Video Editing

Video editing is the process of manipulating and rearranging video shots to create a new work. Editing is usually considered to be one part of the post production process — other post-production tasks include titling, colour correction, sound mixing, etc.

Many people use the term editing to describe all their post-production work, especially in non-professional situations. Whether or not you choose to be picky about terminology is up to you. In this tutorial we are reasonably liberal with our terminology and we use the word editing to mean any of the following:
  • Rearranging, adding and/or removing sections of video clips and/or audio clips.
  • Applying colour correction, filters and other enhancements.
  • Creating transitions between clips.

The Goals of Editing

There are many reasons to edit a video and your editing approach will depend on the desired
outcome.
Before you begin you must clearly define your editing goals, which could include any of the following:
Remove unwanted footage
This is the simplest and most common task in editing. Many videos can be dramatically improved by
simply getting rid of the flawed or unwanted bits.
Choose the best footage
It is common to shoot far more footage than you actually need and choose only the best material for
the final edit. Often you will shoot several versions (takes) of a shot and choose the best one
when editing.
Create a flow
Most videos serve a purpose such as telling a story or providing information. Editing is a crucial
step in making sure the video flows in a way which achieves this goal.
Add effects, graphics, music, etc
This is often the "wow" part of editing. You can improve most videos (and have a lot of fun) by
adding extra elements.
Alter the style, pace or mood of the video
A good editor will be able to create subtle mood prompts in a video. Techniques such as mood
music and visual effects can influence how the audience will react.
Give the video a particular "angle"
Video can be tailored to support a particular viewpoint, impart a message or serve an agenda.

Different Types of Video Editing

There are several different ways to edit video and each method has its pros and cons. Although
most editors opt for digital non-linear editing for most projects, it makes sense to have an
understanding of how each method works.
This page provides a very brief overview of each method — we will cover them in more detail
in other tutorials.

Film Splicing

Technically this isn't video editing, it's film editing. But it is worth a mention as it was the first way
to edit moving pictures and conceptually it forms the basis of all video editing.
Traditionally, film is edited by cutting sections of the film and rearranging or discarding them.
The process is very straightforward and mechanical. In theory a film could be edited with a pair
of scissors and some splicing tape, although in reality a splicing machine is the only practical solution.
A splicing machine allows film footage to be lined up and held in place while it is cut or
spliced together.

Tape to Tape (Linear)

Linear editing was the original method of editing electronic video tapes, before editing computers
became available in the 1990s. Although it is no longer the preferred option, it is still used in some
situations.
Linear Editing Configuration
In linear editing, video is selectively copied from one tape to another. It requires at least two video
machines connected together — one acts as the source and the other is the recorder.
The basic procedure is quite simple:
  1. Place the video to be edited in the source machine and a blank tape in the recorder.
  2. Press play on the source machine and record on the recorder.
The idea is to record only those parts of the source tape you want to keep. In this way desired
footage is copied in the correct order from the original tape to a new tape. The new tape becomes
the edited version.
This method of editing is called "linear" because it must be done in a linear fashion; that is, starting
with the first shot and working through to the last shot. If the editor changes their mind or notices
a mistake, it is almost impossible to go back and re-edit an earlier part of the video. However,
with a little practice, linear editing is relatively simple and trouble-free.

Digital/Computer (Non-linear)

Digital Editing Software
In this method, video footage is recorded (captured) onto a computer hard drive and then edited
using specialized software. Once the editing is complete, the finished product is recorded back to
tape or optical disk.
Non-linear editing has many significant advantages over linear editing. Most notably, it is a very
flexible method which allows you to make changes to any part of the video at any time. This is
why it's called "non-linear" — because you don't have to edit in a linear fashion.
One of the most difficult aspects of non-linear digital video is the array of hardware and software
options available. There are also several common video standards which are incompatible with
each other, and setting up a robust editing system can be a challenge.
The effort is worth it. Although non-linear editing is more difficult to learn than linear, once you
have mastered the basics you will be able to do much more, much faster.

Live Editing

In some situations multiple cameras and other video sources are routed through a central mixing
console and edited in real time. Live television coverage is an example of live editing.
Live editing is a fairly specialist topic and won't concern most people.

Video Editing Terminology

Capture Device: A hardware or firmware device used to convert analogue video into digital video.
Compressors & Codecs: Software or firmware used to compress and decompress digital video.
Compression makes the file size smaller.
Editing: The process of rearranging, adding and/or removing sections of video clips. Also, creating
transitions between clips. Editing is part of post-production.
Encoding: The process of converting digital video into a particular format, for example, saving a
video project in MGEG-2 format for DVD distribution.
Layering: Adding multiple layers of superimposed video.
Linear Editing: Also known as tape to tape editing. A method of editing in which footage is
copied from one tape to another in the required order.
Non Linear Editing: An editing method which uses computer software to edit the footage.
Transition: The way one shot changes to the next .
Post Production: Everything that happens to the video and audio after production, i.e. after the
footage has been shot. Post production includes video editing, audio editing, titling, colour
correction, effects, etc.


Video marketing is becoming one of the rising trends in recent times in the marketing domain.
Most of the companies today are using the tool of video marketing and this is resulting in increasing
their sales manifold. In this fast-paced world a customer rather watch a short video rather than
reading an article which conveys the same message. With more and more companies opting for
video marketing lot of video editing tools are being developed and used in the market.
With the advent of many social video sharing platforms such as YouTube, Vimeo, Instagram, etc.
editing and creating videos has become very popular these days. There are a lot of software available
online which can be used to create and edit videos online without having the need to download
the software. In this article we have listed some of the most popular online video editing tools.
