We examine the ability of an invasive population to traverse hostile environments of differing widths and adversity, under different models for population growth.

More on ARC job cuts & restructure:

ARC’s spending $374k on consultants for organisational β€œreview” & β€œplanning & development”.

They’re also spending $765k on β€œrisk management”.

That’s $1.1 million on consultants being spent over 1 year.

Un. Believable.

Slow clap, ARC.

Microsoft's head of AI doesn't understand why people don't like AI, and I don't understand why he doesn't understand because it's pretty obvious Is it really "mindblowing" that people are skeptical of software that consistently doesn't do the things we're told it can do?

As an English speaking country (with nice beaches to boot) for the cost of a small tax on fossil fuel exports or high incomes Australia could invest in science, recruit researchers fleeing the US and become the knowledge powerhouse of the 21st Century. Instead we're doing this.

Forrest-backed study links Woodside mega-project to hundreds of deaths The research, conducted by academics at ANU, suggests the massive offshore gas project off the coast of Western Australia will cause warming of 0.00039 degrees.

A new study published in Nature Climate Action finds Woodside’s Scarborough gas project could cause 100s of heat-related deaths & exposed 500k people to unprecedented heat.

Govt can’t claim climate leadership while approving projects like this.
