Extreme Droughts Weaken Trees' Ability To Soak Up Carbon

There’s a mystery inside trees upon which the fate of coastal cities, threatened by rising sea levels from climate change, may depend. Each year, the Earth’s forests take up about one-quarter of the carbon dioxide emitted by humans, effectively slowing the speed and severity of global warming. They lock up most of this carbon in their stems and keep it there for centuries. This service that they provide to humanity is worth about $US1 trillion each year.


GPS Has Revealed How The Oldest Multicellular Organisms Had Sex

The global positioning system (GPS) can keep you from getting lost, manage air traffic, and track the migration of endangered species. And in a new study published today by Nature, it’s helped palaeontologists understand how an organism that’s been extinct for about 540 million years reproduced.


The Future Will Be Full Of Lab-Grown Meat

In 2013, the world’s first lab-grown burger was unveiled to the world. It carried a $US330,000 price tag, and apparently, it wasn’t all that tasty. But the scientists behind the idea have been hard at work, and artificial meat that’s both cost-effective and palatable may arrive sooner than we think.


Go Inside A Museum's Animal Dissection Lab, If You Dare 

There’s always a lot going on behind the scenes at museums. For example, in the basement of Chicago’s Field Museum, researchers prepare the specimens that will be studied and displayed at the museum — and then they post that gnarly goopiness on YouTube through a channel the museum maintains.


Greener, Not Cleaner: How Trees Can Worsen Urban Air Pollution

No one enjoys choking on smog, but are more trees really the answer for polluted city air? It’s not as clear-cut as you might think. Air pollution is clearly a problem for health and well-being — and as more and more people across the world move to live in megacities, they could miss out on the fresh air associated with the green countryside.


Everything You Need To Know About Obama's Clean Energy Plan

Last month, scientists at a UN conference delivered a sobering warning: To prevent catastrophic warming of the planet, we must reduce all carbon emissions to zero by the end of the 21st century. Today, the Obama administration announced its plan to get there.


New Graphene-Based Material May Transform Night Vision And Cameras

When physicists Swastik Kar and Srinivas Sridhar were tasked by DARPA to modify graphene so that it provided thermal sensitivity like that of infrared imaging devices, they didn’t know what they’d end up with. Now, through hard work and a little luck, they have a new kind of super material on their hands.


Scientists Can Now Make Nanoparticle Sheets That Curl Right Up

This isn’t a dirty, peeling sticker but a scientific first. Researchers have been able to make complex 2D and 3D structures using nanoparticles for years — but they have never before been able to curve or fold a flat sheet of them like this.


A New Kind Of Masking Tape Will Save The Aerospace Industry Millions

When engineers build planes, they use heavy aluminium masking tape to cover up surfaces during production. Now, engineers at BAE Systems have created a new kind of tape that leaves the surface clean when it’s peeled away — and it’s reckoned it will save them $US70 million.


There's A Rocky Exoplanet Just 21 Light-Years Away

NASA has proven itself to be quite adept at finding planets lately, and this week is no exception: using the Spitzer Space Telescope, scientists at the Jet Propulsion Lab have found HD 219134b, a rocky exoplanet ‘just’ 21 light-years away.
