Despite an overwhelming consensus among climate scientists that warming trends over the past century are most likely the result of human activities, some claim that a plateau in global surface air temperatures since 2001 is evidence to the contrary. However, a new study suggests the recent stabilization of air temperatures is a result of abnormally strong east to west trade winds, causing warmth to be stored temporarily beneath the western Pacific ocean.  Read More

By restoring communication between a cell’s mitochondria (shown here from a mammalian lung...

With the wide-ranging benefits of reducing disease and enabling a longer, healthier life, reversing the causes of aging is a major focus of much medical research. A joint project between the University of New South Wales (UNSW) in Australia and Harvard Medical School that restored communication within animal cells has the potential to do just that, and maybe more. With the researchers hoping to begin human clinical trials in 2014, some major medical breakthroughs could be just around the corner.  Read More

Research at UNSW increases the conversion efficiency of solar cells made using lower-cost,...

While we wait for affordable multi-junction solar cells that are pushing past the 40 percent conversion efficiency mark to make it out of the lab and onto our roofs, we have to make do with standard commercial silicon cells that currently max out at around 19 percent. A team from the University of New South Wales in Australia has found a way to improve the quality of low-grade silicon, enabling higher efficiency solar cells to be produced from cheaper, low-grade silicon.  Read More

Australian scientists have successfully revived and reactivated the genome of an extinct frog. The "Lazarus Project" team implanted cell nuclei from tissues collected in the 1970s and kept in a conventional deep freezer for 40 years into donor eggs from a distantly-related frog. Some of the eggs spontaneously began to divide and grow to early embryo stage with tests confirming the dividing cells contained genetic material from the extinct frog.  Read More

Australian scientists have developed a promising new approach to hydrogen storage

Scientists at the University of New South Wales (UNSW), Australia, are developing a novel way to store hydrogen that could help turn it into a viable portable fuel source. The research centers on using synthesized nanoparticles of the compound sodium borohydride (NaBH4 for those who love chemistry), which when encased inside nickel shells exhibits surprising and practical storage properties including the ability to reabsorb hydrogen and release it at much lower temperatures than previously observed, making it an attractive proposition for transport applications.  Read More

The Weltzeituhr (World Clock) at Alexanderplatz, Berlin, Germany isn't anywhere near as ac...

The NIST-F1 atomic clock that currently serves as primary time and frequency standard for the U.S. is expected to neither gain nor lose a second in more than 100 million years. That might sound pretty accurate, but a proposed nuclear clock could make it look like a cheap digital wristwatch. It is claimed that the proposed clock would neither gain nor lose 1/20th of a second in 14 billion years. To put that in context, that’s the estimated age of the universe.  Read More

Researchers have created silicon wire four atoms wide and one atom tall capable of carryin...

The world's narrowest silicon wires with a cross section of a mere four atoms by one atom have been created by a team of developers from the University of New South Wales, the University of Melbourne and Purdue University. The wires are fully functioning, with current-carrying capacity equivalent to that of a microprocessor's copper cable, despite being 20 times thinner - and 10,000 times narrower than a human hair.  Read More

Spinovo wearable back pain relief concept

Industrial Design student Justine Smith has looked to new technology for a solution to one of the most common ailments in the world today – chronic back pain. The result is Spinovo – a concept smart clothing product that uses modular packs to treat pain through heating, cooling, and transcutaneous electrical nerve stimulation (TENS) therapies as well as incorporating bend sensors to ensure the wearer maintains the correct posture.  Read More

The Sunswift IVy during the 2009 Global Green Challenge

With a speed of 88.738 km/h (55.077 mph), the University of New South Wales’ Sunswift IVy has claimed the Guinness World Record for the fastest solar-powered vehicle. The record-beating run took place on January 7 at HMAS Albatross navy base airstrip in Nowra, Australia, and outdid the previous record-holder by more than 10 km/h (6.2 mph).  Read More

Illustration of the dipolar variation in the fine-structure constant, alpha, across the sk...

Star Trek’s Scotty was adamant that you “canna change the laws of physics,” but, according to a report from a team of astrophysicists based in Australia and England, that could be exactly what happens in different parts of the universe. The report describes how one of the supposed fundamental constants of Nature appears not to be constant after all. Instead, this 'magic number' known as the fine-structure constant – 'alpha' for short – appears to vary throughout the universe.  Read More
