Nuclear fusion power - the ultimate clean energy

(PhysOrg.com) -- Imagine if you could generate electricity using nuclear power that emitted no radioactivity: it would be the answer to the world's dream of finding a clean, sustainable energy source.

Solar cells - I think they can, I think they can

Solar cells: UQAM researcher solves two 20-year-old problems
Thanks to two technologies developed by Professor Benoit Marsan and his team at the Universite du Quebec a Montreal (UQAM) Chemistry Department, the scientific and commercial future of solar cells could be totally transformed. Professor Marsan has come up with solutions for two problems that, for the last twenty years, have been hampering the development of efficient and affordable solar cells.

How many scientists does it take to replace a light bulb? None, cause it never burns out

(PhysOrg.com) -- Light bulbs that last 100 years and fill rooms with brilliant ambiance may become a reality sooner rather than later, thanks to a National Renewable Energy Laboratory discovery.

Can you hold your breath forever?

(PhysOrg.com) -- Oxygen may not be the staple of modern complex life that scientists once thought. Until now, the only life forms known to live exclusively in anoxic conditions were viruses, bacteria and Archaea. But in a new study, scientists have discovered three new multicellular marine species that appear to have never lived in aerobic conditions, and never metabolized oxygen.

Putting oil profits to good use

(PhysOrg.com) -- A new eco-city being built in the United Arab Emirates (UAE), Masdar City, will be the world’s first clean technology city, relying entirely on renewable energy sources, and being free of cars, skyscrapers and waste.

'Organic Electronics' coming soon to a Whole Foods near you

(PhysOrg.com) -- A new technique developed by Princeton University engineers for producing electricity-conducting plastics could dramatically lower the cost of manufacturing solar panels.

Bacteria don't like getting poked

ScienceDaily (2010-03-15) -- For two decades, scientists have been pursuing a potential new way to treat bacterial infections, using naturally occurring proteins known as antimicrobial peptides (AMPs). Now, scientists have recorded the first microscopic images showing the deadly effects of AMPs, most of which kill by poking holes in bacterial cell membranes.

I love gooooold. But cancer sure doesn't

ScienceDaily (2010-03-16)
-"Magic Bullets" are highly targeted medical treatments which are the ultimate goal for drug development.
-Cancer has evaded these so-called bullets because of drastic changes in tumors between (1) different stages of cancer development, (2) different organs/tissues of the body, and (3) different patients.
-A new treatment developed at Washington University in St. Louis may be able to target cancer cells and selectively kill them with minimal damage to healthy cells.
-The technique is called 'Photothermal Therapy' and involves injecting gold nanocages into a patient's bloodstream (gold is inert and therefore nontoxic at low levels).
-Some of these 'golden bullet' nanocages accumulate at the tumor site (~6%) through leaky blood vessels (a commonality between tumor).
-A laser is then shone on the tumor site and the nanocages present convert light into heat which leads to the death of the tumor cells and has little/no effect on the surrounding healthy cells.
-This treatment was shown to work in a mouse model, but with the way things are currently for translating developments from the lab-to-clinic, this technology should be available in 100 years or so.
-This treatment isn't perfect yet, more research has begun on actively targeting cancer cells so fewer particles need to be injected, but is a huge tool in treating cancer which could be effective right now!

Frogs, foam and fuel: Solar energy converted to sugars

ScienceDaily (2010-03-17) -- In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant -- like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers are doing something about that.

Splitting water into hydrogen and oxygen, sort of like the Moses of chemistry

ScienceDaily (2010-03-18) -- Chemists have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using only water and sunlight.
