My new story for Gizmodo: Climate Change apparently is here–to survive and thrive, go transhuman. The essential thing to remember here is that environmental change creates a mandate for our species to speed up technological progress to make sure we can adapt to changing conditions on Earth.

Scientists say we blew it. We bought too many plastic trinkets from Walmart; we drove too many gas-guzzling Broncos. We made babies like rabbits without questioning if the planet could handle so many people. Well, it looks like it couldn’t. Climate change is here to stay, and it’ll probably end up affecting nearly every aspect of our lives over the next century.

A team of researchers from Berkeley Lab and Columbia University has created “the world’s highest-performance single-molecule diode,” using a combination of gold electrodes and an ionic solution.

The diode’s rectification ratio (ratio of forward to reverse current at fixed voltage) is in excess of 200, “a record for single-molecule devices,” says Jeff Neaton, Director of the Molecular Foundry, a senior faculty scientist with Berkeley Lab’s Materials Sciences Division and the Department of Physics at the University of California Berkeley and a member of the Kavli Energy Nanoscience Institute at Berkeley (Kavli ENSI).

The Millennium Project released today its annual “2015–16 State of the Future” report, listing global trends on 28 indicators of progress and regress, new insights into 15 Global Challenges, and impacts of artificial intelligence, synthetic biology, nanotechnology and other advanced technologies on employment over the next 35 years.

“Another 2.3 billion people are expected to be added to the planet in just 35 years,” the report notes. “By 2050, new systems for food, water, energy, education, health, economics, and global governance will be needed to prevent massive and complex human and environmental disasters.”

Titan, former world’s fastest supercomputer (credit: Oak Ridge National Laboratory)

President Obama has signed an executive order authorizing the National Strategic Computing Initiative (NSCI), with the goal of creating the world’s fastest supercomputers. The NSCI is charged with building the world’s first-ever exascale (1,000-petaflops) computer — 30 times faster than today’s fastest supercomputer.

The order mandates:

Massachusetts General Hospital investigators have induced subcutaneous fat cells in a piece of skin from a pig to emit laser light in response to energy delivered through an optical fiber (credit: Matjaž Humar and Seok Hyun Yun/Nature Photonics)

Imagine being able to label a trillion cells in the body to detect what’s going on in each individual cell.

That’s the eventual goal of a Massachusetts General Hospital (MGH) study to allow individual cells to produce laser light. The wavelengths of light emitted by these intracellular microlasers differ based on factors such as the size, shape, and composition of each microlaser, allowing precise labeling of individual cells.

Once again telomeres are shown to be key players in aging.

The secret to living long, healthy lives and ageing beyond 100 has finally been cracked, according to a new study.

Scientists at Newcastle University say they have identified the key to longevity and good health amongst centenarians and how they pass that gift onto their offspring.

The K supercomputer in Japan. The human brain is arguably the most complex structure in the Universe. To unlock its secrets, scientists all over the world are mapping and simulating parts of the human brain. The latest breakthrough comes from Japan where scientists using the K supercomputer, the fourth most powerful in world, accurately mapped one second’s worth of brain activity. It took the computer 40 minutes to undertake this task, for one percent of the brain activity!
