Alcohol may boost risk of cancer for Asians

August 23, 2012


Almost 30 years after discovery of a link between alcohol consumption and certain forms of cancer, scientists are now reporting the first evidence from research on people explaining how the popular beverage may be carcinogenic.

The results, which have special implications for hundreds of millions of people of Asian descent, were reported here today at the 244th National Meeting & Exposition of the American Chemical Society.

Algae and Light Help Injured Mice Walk Again

October 22, 2009

“In theory, two-way optogenetic traffic could lead to human-machine fusions in which the brain truly interacts with the machine, rather than only giving or only accepting orders,” says writer Michael Chorost.

“It could be used, for instance, to let the brain send movement commands to a prosthetic arm; in return, the arm’s sensors would gather information and send it back. Blue and yellow LEDs would flash on and off… read more

Algae as a hydrogen fuel source

April 2, 2008

Argonne National Laboratory scientists are engineering algae’s photosynthesis process to produce hydrogen gas by adding the enzyme hydrogenase.

Algae that naturally have hydrogenase produce only small volumes of hydrogen. With the enzyme added to photosynthesis the algae should produce as much hydrogen as oxygen.

Algae can switch quantum coherence on and off

Could allow the energy to test every possible pathway simultaneously before traveling via the quickest route

Algae that survive in very low levels of light and are able to switch quantum coherence on and off have been discovered by a UNSW-led team of researchers.

The function for this effect, which occurs during photosynthesis, remains a mystery. But working out its role in a living organism could lead to technological advances, such as better organic solar cells and quantum-based electronic devices.

European researchers have demonstrated a new method for hydrogen production by algae.

In a recent issue of PNAS, the team presented a method using copper to block oxygen generation in the cells of Chlamydomonas reinhardtii that could lead to a consistent cycle of hydrogen production.

Algae molecular transporter could advance biofuels, pharmaceuticals

Molecular transporter breaks algae cell-wall barrier

Proof that it works. In the left microscopy image, obtained during a control experiment, a green fluorescent tracer called fluorescein is not delivered inside algae cells when the tracer is only mixed with the molecular transporter. In the right image, fluorescein is successfully delivered inside algae cells when it’s covalently linked to the molecular transporter. (Image courtesy of Parvin lab)

Scientists have developed a way to send molecules and proteins across the cell wall of algae, a feat that opens the door for a new way to study and manipulate these tiny organisms.

In recent years, algae have become a hot prospect as a way to synthesize biofuels, chemical building blocks, vaccines, pharmaceuticals, and other useful compounds.

The idea is to engineer algae to secrete fuel for… read more

Algae to solve the Pentagon’s jet fuel problem

February 15, 2010

The Defense Advanced Research Projects Agency (DARPA) says it is just months away from producing a jet fuel from algae for the same cost as its fossil-fuel equivalent, part of a broader mission for the US military to obtain half of its fuel from renewable energy sources by 2016.

DARPA’S research projects have already extracted oil from algae ponds at a cost of $2 per gallon. It is now… read more

Algae-Based Fuels Set to Bloom

February 5, 2007

Raw algae can be processed to make biocrude, the renewable equivalent of petroleum, and refined to make gasoline, diesel, jet fuel, and chemical feedstocks for plastics and drugs. Indeed, it can be processed at existing oil refineries to make just about anything that can be made from crude oil.

New genomic and proteomic technologies make it much easier to understand the mechanisms involved in algae-oil production.

Algae: Biofuel of the future?

August 19, 2008

University of Virginia researchers have a plan to greatly increase algae oil yields by feeding the algae extra carbon dioxide (the main greenhouse gas) and organic material like sewage, meaning the algae could simultaneously produce biofuel and clean up environmental problems.

Algorithm identifies top ten technology news trend setters

July 5, 2012


Berlin Institute of Technology researchers studied the problem of trend-setting among news sites to determine which websites lead the news coverage and which ones merely follow, Technology Review Physics arXiv Blog reports.

They took a snapshot of the words generated by 96 technology news websites at any instant in time and compared them to the words generated by one of these websites at an earlier time.

This allowed them… read more

Algorithmic stock trading rapidly replacing humans

September 9, 2011

Algorithmic trading (high frequency trading) is rapidly replacing human decision making, according to a UK government panel, which warned that the right regulations need to be introduced to protect stock markets.

Quid Map

A startup called Quid has developed algorithms that analyze Internet-based data from corporations to make fast-moving technology developments visible, navigable, and understandable.

Quid has built a data set combining information about firms that succeeded and sank, patent documents, government grants, help wanted advertisements, and tweets. Its algorithms use the collection of information to analyze the prospects of around 35,000 firms and research groups working on new technologies.… read more

Alice Chatbot Wins for Third Time

September 20, 2004

Richard Wallace’s Alice chatbot program beat three other finalists to take the 2004 bronze metal for the Loebner Prize competition.

The bronze metal goes to the program best able to maintain a life-like conversation. No program has won gold or silver metals, which will go to programs able to convince half the judges that the program is a human, either via video (gold) or text (silver).… read more

Alien Animal Planet

February 6, 2006

Computer models created by NASA and SETI Project researchers have helped identify which stars among the universe’s 70 sextillion are most likely to support life.

They used two scenarios formulated by the SETI Project: a planet orbiting a sun close enough to keep water from freezing out, yet far enough away to avoid evaporation and a moon orbiting a gas giant and warmed by twin suns.

Then life… read more
