Weekly Science Picks

It is with a heavy heart that I must say, this is my final set of Weekly Science Picks here on Australian Science. In fact, it’s to be the final set of Weekly Science Picks. Unfortunately, running a site like [...]

Weekly Science Picks

Well, it’s my turn to pick my favourite science news this week on Australian Science. And I must apologise for being slightly late with this. The reason is that I’ve only just got home to Tokyo after spending all week [...]

Weekly Science Picks

I’m loath to begin a weekly roundup on a low note, and I’m truly sorry to have to, but this most certainly needs to be discussed. It’s been a turbulent week this week in the science blogging world. Turbulent and [...]

The Hallmarks of Cancer: Becoming Independent

This article originally appeared on Know The Cosmos. I will be re-posting excerpts here for Australian Science with added commentary over the coming weeks! “The Hallmarks of Cancer” are ten anti-cancer defense mechanisms that are hardwired into our cells, that [...]

Growth Factors are beautiful! This is a 3D schematic representation (also known as a ribbon diagram) of the structure of a growth factor known as Vascular Endothelial Growth Factor (VEGF). VEGF stimulates the development of new blood vessels, a process known as angiogenesis. Many large tumors secrete their own supply of VEGF in order to generate a supply line of oxygen-rich blood for the growing tumor to feed on. Image credit: Gizmag

Combating the rise of the superbugs: The health and scientific challenges of antibiotic resistance

It’s hard to imagine the world prior to antibiotics, a world where even a deep laceration could frequently spell significant illness or even death due to infection. Thankfully, since the discovery of penicillin in 1929 by Alexander Fleming, we now [...]

Asteroids, extinctions, and biodiversity: Wiping the slate clean for new life to flourish

The recent meteor strike in Russia has been a rather sobering reminder that Earth has been regularly battered during its history, by space rocks. Actually, the amount of meteoritic material constantly landing on Earth is startling – on average, over [...]

The bacteria that live inside hurricanes

Seven miles above the Earth’s surface, where the weather is born, lies the troposphere – the lowest layer of Earth’s atmosphere. Up there, where the clouds dance around, are bacteria that can make it rain, and are important for the [...]
