Entropy Theories in State of Disorder

During this flight Hawking experienced eight such periods. Now one of his theories about entropy is in freefall too. Photo: NASA

Australian researchers have found that there is more disorder in the universe than previously realised – and that one of Stephen Hawking’s assumptions is probably wrong.

Neutrino Hint from Radioactivity Puzzle

By Peter Pockley

The discovery that the decay rates of radioactive isotopes may not be immutable "constants of nature" could open fresh ways of detecting neutrinos and protecting astronauts and satellites in space.

Patterned polymer surfaces based on the African Stenocara beetle could be applied to our roofs to collect drinking water from the atmosphere.

Maintaining a stable supply of drinking water in Australia is a continual challenge. In 2006 the drought that gripped most of the Australian mainland was termed “the worst drought in 1000 years”, with the once-ferocious Murray River receiving only 5% of its average inflow.

A Matter Of Time

Successful treatment of cancer may depend on the accurate timing of chemotherapy or vaccine therapies to match fluctuations in each patient’s immune system.

Not all cancer patients are cured by chemotherapy, biological therapies, radiotherapy or surgery. Some patients can have complete regression of all cancer, while others do not appear to be responding or show some level of clinical response but not enough to overcome the tumour.

This variability has remained unexplained for many decades, and at the end of this week about 800 Australians with cancer will be dead. In the US the numbers will be close to 12,000 per week.

The Top 10 WEIRD Science Stories of 2018

By AusSMC

There was no shortage of weird and wonderful science in 2018.

There was no shortage of weird and wonderful science in 2018 - octopuses were high on ecstasy, a billionaire shot a car into space, scientists injected memories between sea snails and someone started a petition to drink the 'mummy juice' found in a 2,000-year-old sarcophagus, among many other peculiar science tales.


Scientists gave octopuses ecstasy and they started hugging
