Mechanical engineers leading effort to detect defects that reduce efficiency

Posted by in categories: climatology, economics, government, solar power, sustainability

Gets too advanced for me, but still interesting.


As the world transitions to a low-carbon energy future, near-term, large-scale deployment of solar power will be critical to mitigating climate change by midcentury. Climate scientists estimate that the world will need 10 terawatts (TW) or more of solar power by 2030—at least 50 times the level deployed today. At the MIT Photovoltaics Research Laboratory (PVLab), teams are working both to define what’s needed to get there and to help make it happen. “Our job is to figure out how to reach a minimum of 10 TW in an economically and environmentally sustainable way through technology innovation,” says Tonio Buonassisi, associate professor of mechanical engineering and lab director.

Their analyses outline a daunting challenge. First they calculated the growth rate of solar required to achieve 10 TW by 2030 and the minimum sustainable price that would elicit that growth without help from subsidies. Current technology is clearly not up to the task. “It would take between $1 trillion and $4 trillion of additional debt to just push current technology into the marketplace to do the job, and that’d be hard,” says Buonassisi. So what needs to change?

Graphene oxide supercapacitor commercial prototype targeted within 2 years

Posted by in categories: 3D printing, energy, transportation

OMG? Are we going to have super cheap electric vehicles in a few years that charge in a few seconds/minutes?

I hope so! This is very exciting.


Australia has supercapacitors made from graphene oxide. They can can store as much energy per kilogram as a lithium battery, but charges in minutes, or even seconds, and uses carbon instead of expensive lithium.

Creative people have better-connected brains

Posted by in category: neuroscience

For those scientists that know creativity is important.


Seemingly countless self-help books and seminars tell you to tap into the right side of your brain to stimulate creativity. But forget the “right-brain” myth — a new study suggests it’s how well the two brain hemispheres communicate that sets highly creative people apart.

Cancer cells hijack healthy cells to help them spread to other organs

Posted by in categories: bioengineering, biotech/medical

An interaction between two proteins enables cancer cells to use the physical forces of healthy cells to start spreading to other parts of the body.

The finding by researchers from the Francis Crick Institute in London and the Institute for Bioengineering of Catalonia (IBEC) in Barcelona is published in the journal Nature Cell Biology.

The process by which cancer cells separate from the original tumour to form new tumours in other organs or tissues of the body is called metastasis, and it is responsible for the majority of deaths in patients with cancer.

Canada to Spend $750 Million to Ensure All Citizens Have Internet Access

Posted by in categories: government, internet, mobile phones

In Brief

  • Canada is spending millions to ensure all citizens have access to home internet with download speeds of at least 50Mbps and upload speeds of 10Mbps in the next 10 to 15 years.
  • At a time when so many things we used to do in person or via a physical medium are done digitally, living without the internet inherently puts a person at a disadvantage.

Canada is making some major moves to ensure that every citizen in the country has access to fast broadband speeds. The Canadian Radio-Television and Telecommunications Commission (CRTC) announced this week that it was setting up a fund of $750 million available over the next five years to expand internet access.

The CRTC is implementing a standard of universal availability of home internet with download speeds of at least 50Mbps and upload speeds of 10Mbps with the option of unlimited data. In doing so, the Canadian government is declaring that broadband internet is a basic telecommunications service, akin to phone service.
