Top 10 Ridiculous Science Experiments You Can Do At Home.


article-0-15D08329000005DC-593_634x348

From time to time we enjoy posting some of the latest happenings in science on this blog, but it has come to our attention that a particular little future female scientists wanted some simpler things to read. Most of the science stuff is rather adult, but brining home-style science to younger readers is “elementary”… so here are 10 top home made science experiments that young ones can do at home.

 

Science Has Just Had A Global Breakthrough… Have You Heard?

Irish researchers have achieved a breakthrough in the production of ‘wonder material’ graphene.  Scientists at the AMBER, a materials science centre at Trinity College Dublin and funded by Science Foundation Ireland, have discovered a way to produce the material in industrial quantities.  What makes “Graphene” so incredible you may ask?  The substance is one the strongest known with a section 1mm thick being 200 times stronger than steel and a superconductor of electricity more than 1000 times more effective than copper.  It’s also 97.3 per cent transparent and extremely bendable.

Until now, it was extremely difficult to produce because it is essentially a  single-atom thick sheets of carbon made from graphite.  In mass quantities, graphene could potentially revolutionize many parts of our lives, from providing the next step in battery technology, biomedical sensors, water filtration, to even photovoltaic cells used in solar panels  The Dublin findings are to be published in the Nature Materials publication, heralded as a ‘global breakthrough’.  “This shows how industry and academic collaboration can lead to research of the highest calibre, with real commercial applications,” Prof Jonathan Coleman from AMBER said.  “Graphene has been identified as a life changing material and to be involved at this stage of development is a wonderful achievement.”

Minister for Research and Innovation Sean Sherlock praised the team’s work, saying producing graphene in mass quantities is “something that USA, China, Australia, UK, Germany and other leading nations have all been striving for and have not yet achieved”. Thomas Swan Ltd have now signed a contract with AMBER to scale-up production.  The project was part of the Graphene Flagship, spanning 17 countries with 126 academics as well as industry partners working on a common goal, and was part of the €1 billion research project announced by the EU, of which Ireland received 1 per cent.

Plug your phone in for five seconds and it would be all charged up. The downside here is that you won’t be able to use a dead phone as an excuse anymore.

 

What if we actually had a clear solution for cleaning up the tainted water near Fukushima? Scientists at Rice say graphene could potentially clump together radioactive waste, making disposal is a breeze.

 

Water, water everywhere and EVERY drop drinkable. MIT mindshave a plan for a graphene filter covered in tiny holes just big enough to let water through and small enough to keep salt out, making salt water safe for consumption.

 

Touchscreens that use graphene as their conductor could beslapped onto plastic rather than glass. That would mean super thin, unbreakable touchscreens and never worrying about shattering your phone ever again.

 

Just a single sheet of graphene could produce headphones that have a frequency response comparable to a pair of Sennheisers, as some scientists at UC Berkeley recently showed us.

 

High-power graphene supercapacitors would make batteries obsolete.  You wouldn’t have to charge your phone for years.

 

Graphene could pave the way for bionic devices in living tissues that could be connected directly to your neurons. So people with spinal injuries, for example, could re-learn how to use their limbs.

How Siri Found Its Voice


Siri

Technology, science, art, and culture website The Verge have created a film giving us a unique look at the inner workings of Nuance Communications – the company responsible for creating Siri’s voice on iOS. The 10-minute documentary charts the history of voice synthesisation from its origins in cars like the Chrysler New Yorker in 1983 through to modern day use in products like TomTom and iPhone. We also hear from voiceover “talent” like Allison Dufty, who was first discovered while reading out the specials in a restaurant.

Box Jellyfish

The infamous box jellyfish developed its frighteningly powerful venom to instantly stun or kill prey, like fish and shrimp, so their struggle to escape wouldn’t damage its delicate tentacles. Their venom is considered to be among the most deadly in the world, containing toxins that attack the heart, nervous system, and skin cells. It is so overpoweringly painful, human victims have been known to go into shock and drown or die of heart failure before even reaching shore. Survivors can experience considerable pain for weeks and often have significant scarring where the tentacles made contact. Box jellies, also called sea wasps and marine stingers, live primarily in coastal waters off Northern Australia and throughout the Indo-Pacific. They are pale blue and transparent in color and get their name from the cube-like shape of their bell. Up to 15 tentacles grow from each corner of the bell and can reach 10 feet (3 meters) in length. Each tentacle has about 5,000 stinging cells, which are triggered not by touch but by the presence of a chemical on the outer layer of its prey.

Box jellies are highly advanced among jellyfish. They have developed the ability to move rather than just drift, jetting at up to four knots through the water. They also have eyes grouped in clusters of six on the four sides of their bell. Each cluster includes a pair of eyes with a sophisticated lens, retina, iris and cornea, although without a central nervous system, scientists aren’t sure how they process what they see.
