Nano-sand to improve lotions and cosmetics

Patented South Australian technology

South Australian researchers have invented and patented a new technology for delivering cosmetics and drugs to the skin.They are using nanoparticles of silica (essentially sand) to create longer lasting cosmetics and creams that control the delivery of drugs through the skin.

They already have a family of international patents on their technology, and are now actively looking for commercial partners to get their invention out of the lab and on to your skin.

 

“We are using specially engineered nanoparticles of silica—so small that about a thousand of them could fit across a human hair—to create the emulsions on which many cosmetic and therapeutic products are based,” says Nasrin Ghouchi-Eskandar from the University of South Australia’s Ian Wark Research Institute.

The work is being presented for the first time in public through Fresh Science, a communication boot camp for early-career scientists held at the Melbourne Museum. Nasrin was one of 16 winners from across Australia.

Print your own lasers, lights and TV screens

Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and his colleagues at CSIRO, the University of Melbourne and the University of Padua in Italy, have moved a step closer to such a future, by developing liquid inks based on quantum dots that can be used to print devices.

These quantum dot inks will transform our use of light in the home and office. In the first demonstration of these inks Jacek and his colleagues have made tiny printable lasers.

The first laser, invented 50 years ago in May 1960, was described as a solution looking for a problem. Today dozens of lasers are built into our computers, cars and homes. Soon, thanks to Jacek’s work, we may have millions of tiny lasers working in our homes lighting our rooms and even acting as pixels in printable TV screens. The lasers could also be used as components in optical computers, electronics, sensors, as cheap laser pointers in a range of colours or even fashion accessories.

Jacek’s work is being presented for the first time in public through Fresh Science, a communication boot camp for early-career scientists held at the Melbourne Museum. Jacek was one of 16 winners from across Australia.

Aussie lizard reveals cancer secrets

A compound produced by a pregnant lizard may provide important information on the origins and treatment of cancer in humans, according to zoologist Bridget Murphy from the University of Sydney, who discovered the protein, which is pivotal to the development of the lizard placenta.

“Our egg-laying ancestors probably never got cancer, but things changed when we started having live young. Embryos need an extensive network of blood vessels to allow them to grow. So do tumours.  I found that the three-toed skink, which gives birth to live young, uses a particularly powerful protein to encourage the growth of blood vessels. The only other place where this protein has been found is in pre-cancerous cells grown in the laboratory,” she says.

Future research on unlocking the secrets of how the protein works might well provide the basis of new therapies for cancer, and to promote wound healing or the regeneration of blood vessels in patients with heart disease. Bridget’s work is being presented for the first time in public through Fresh Science, a communication boot camp for early career scientists held at the Melbourne Museum. She was one of 16 winners from across Australia.

Joint reversal eases arthritis

A shoulder-joint implant, with the ball and socket on the opposite bones from nature, can significantly improve the quality of life of patients with severe arthritis and tendon tears, says medical engineer David Ackland from the University of Melbourne.

In a search for a more effective replacement joint, David and his colleagues looked at the counterintuitive ‘reverse’ implant, which was designed and manufactured in the US by Zimmer, Inc. Their tests on the Zimmer implant showed that it stabilises the joint and increases the range of movement of arthritic shoulders. His work is being presented for the first time in public through Fresh Science, a communication boot camp for early career scientists held at the Melbourne Museum last week. David was one of 16 winners from across Australia.

Add fertiliser to fight weeds

Feeding weeds fertiliser sounds like exactly the wrong thing, if you want to get rid of them, but Jennifer Firn of CSIRO Sustainable Ecosystems has been doing just that—to control African lovegrass, an invasive species of rangelands in every Australian state.

Her method works by making the weed tastier to grazing animals. It illustrates that we need to be smarter in dealing with weeds, not just reaching for the Round Up, Jennifer says. Her work was published in the Journal of Applied Ecology earlier this year and is being presented for the first time in public through Fresh Science, a communication boot camp for early career scientists held at the Melbourne Museum last week. She was one of 16 winners from across Australia.

Will eco-warrior billionaires hack the earth?

“Our failure to act on climate change could encourage an underground movement to take action and fix climate change through geo-engineering. It’s a real threat according to leading academics. And the ethics of geo-engineering were explored at a Victorian government backed conference in California earlier this year,” says science commentator Tim Thwaites.

Shock? Horror? Why should we be surprised? As climate provocateur, Bjorn Lomborg pointed out to Robyn Williams recently on the ABC’s Science Show, many geo-engineering possibilities are inexpensive enough to be with the reach of a billionaires like Bill Gates and Richard Branson —and Governments seem hamstrung about coming to agreement on any other action. This makes the ABC online drama project Bluebird timely, as it explores these very issues. [Read more…] about Will eco-warrior billionaires hack the earth?
