eureka prize winners show off australian-grown science ingenuity — from super lasers to killer wings

From powerful diamond lasers to bacteria, researchers are working on everything.
The killing surface material inspired by insect wings was awarded one of Australia\'s top science awards. Forty-
At the awards dinner at Sydney City Hall on Wednesday night, five finalists were reduced to 15 Australian Museum Eureka Prize winners, each sharing a $150,000 prize.
The innovative use technology award has been awarded to a project at the University of Melbourne that found a way to produce medical products cheaply
Grading oxygen without using electricity makes it easier to save the lives of newborns born with suffocation or lung infection.
Meanwhile, Richard milderen, associate professor at Macquarie University, won the Defense Science and Technology Award for his work using diamond to massively extend the range and power of the laser, and one day it could help shoot down drones and missiles.
From elementary school to fourth grade, budding scientists have also won honors in these categories, sydney students Kaitlyn Walker and Amelia Lai won the Eureka Award for their short film, explaining how penguins in Antarctica keep warm.
Kim McKay AO, curator of the Australian Museum, said the awards represent Australia\'s best scientific awards.
\"The Eureka prize winner at the Australian Museum is helping to address some of the biggest challenges facing humanity and the planet,\" she said . \".
Look back at some of the ground --
Contestants who break the Eureka Prize 2017 shortlist: in addition to this sunburned country, where scientists will invent a sticker that will change color when your sun is too big.
Professor Justin Gouding from the new state university, Dr. Patricia kiabani and Dr. Alexander soliadi created a simple sensor to remind people that they need to be in the shade
Smart sensors are cheap and can be printed from ordinary inkjet printers using special inks made of food dyes and titanium dioxide
Active ingredients in many sunscreen.
Just like baking dog dung under Australian sun, the sensor turns white when cooking.
\"It\'s smart because when UV rays hit the paper, the ink loses color,\" said Professor Guding . \".
High-end changes
The sticker can take into account the color of the skin and whether you have applied sunscreen.
Professor Guding said he hopes the sensor will be put on shelves in the next year or two.
Usually, when you think of killing bacteria, you think of attacking them with chemicals.
But researchers at the Swinburne University of Technology found that dragonflies and cicadas had their own wings on the surface.
No chemicals are needed for disinfection.
They capture, stretch, and break bacteria with tiny spikes called nanokholes.
Scientists hope that a new generation of wing-based nano-materials will provide an antibacterial surface for medical implants, thus physically preventing and killing bacteria.
Professor Elena Ivanova, Swinburne researcher, said the new surface has exciting potential in the fight against antibiotics
Resistant bacteria.
\"Because this is a mechanical process, it is unlikely that bacteria will be resistant to this material,\" she said . \".
The project won the Eureka Science Research Award, which impressed the judges.
Pollution, including sewage being pumped into the ocean including Bondi Beach, is thought to have killed a huge 70-
A kilometer-long undersea seaweed forest.
Crayweed, which supports lobster and abalone, disappeared, and even the improvement of water quality in 1990 seconds could not recover what was lost.
So scientists at the Sydney Institute of Marine Science decided that they would do a big --
Scale transplant of underwater forest.
Action Crayweed started more than five years ago and sought the help of volunteer citizen scientists to replant seaweed in the affected areas from Palm Beach to Botany Bay.
Crayweed was installed on the reef floor on specially designed mats, and in just a few months the new generation of seaweed began to sprout and rejuvenate the coastline.
Doctors may not be known for their clear handwriting, but their calligraphy will soon be used in plastic surgery implant surgery to repair damaged or sick bones.
A team of scientists from Wollongong worked with doctors in Melbourne to make a pen --
Like a handheld 3D printer, it can ship stem cells to where they are needed.
Surgeons will use the ink of Biopen and its living cells and growth factors to fill damaged bones during surgery, which gives them great control and accuracy.
When allocated, the stem cells are wrapped in the gel, and the UV rays on the pen harden the \"gel\" ink.
It is being tested on sheep at St. Vincent\'s Hospital in Melbourne, where stem cells are delivered directly to the knee to regenerate damaged cartilage.
So far, this test shows better results than any treatment currently used in humans.
Professor Peter Choong, plastic surgeon at St. Vincent\'s Hospital, said: \"While we are mainly used for cartilage, we can already see how it can be used in a variety of other clinical situations . \".
If you have kidney disease, you will find that it may cost $50,000 per year to receive dialysis.
This puts a huge burden on many people and locks millions of people around the world who can\'t afford to live.
Salvage treatment
But a new portable invention could cut costs to $1,000.
British engineer Vincent Garvey has won a Global competition launched by the George Institute for Global Health in Australia to create a price-effective
The entrance to the win is solar and shrinking the existing technology to put the whole product into the suitcase.
Affordable dialysis systems use the sun to power small distillers that can purify the machine\'s water.
This is a perfect design for use in remote areas with plenty of sunlight but no disinfectant.
\"We got a chance that you can save millions of lives. It\'s awe-
\"It is encouraging that this is a shocking idea,\" Mr Garvey said . \".
This is the Institute\'s first major leap in dialysis design in more than 50 years. Topics:science-awards,science-and-
