From Science Daily:

ScienceDaily (Sep. 8, 2009) — Aquaculture, once a fledgling industry, now accounts for 50 percent of the fish consumed globally, according to a new report by an international team of researchers. And while the industry is more efficient than ever, it is also putting a significant strain on marine resources by consuming large amounts of feed made from wild fish harvested from the sea, the authors conclude. Their findings are published in the Sept. 7 online edition of the Proceedings of the National Academy of Sciences (PNAS).

How Much Spit Does A Person Produce?

From Live Science:

Our salivary glands, which are located on the inside of each cheek, at the bottom of the mouth and under the jaw at the front of the mouth, churn out about two to four pints (one to two liters) of spit every day.

The mere mention or aroma hint of chocolate chip cookies can make for a mouth full of drool. That's a good thing. The clear substance, made up mostly of water, mixes in with food to help even the driest snack slide with ease down into your stomach. Before those morsels hit the belly, special enzymes in saliva start to break down that food into its simpler components.

Virus Linked To Prostate Tumours

From The BBC:

Scientists have produced compelling evidence that a virus known to cause cancer in animals is linked to prostate cancer in humans.

The researchers from the University of Utah and Columbia University medical schools found the virus in 27% of the 200 cancerous prostates they looked at.

They say it was associated with more aggressive tumours and found in only 6% of non-cancerous prostates.

The finding raises the prospect of one day producing a vaccine.

Previous research has linked XMRV (Xenotropic murine leukaemia virus) to prostate cancer but not in such an aggressive way.

More Rubbish From 60 Minutes Tonight. “The Age Of Megafires”

From Watts Up With That:

Right on cue, CBS news 60 minutes is expected link the recent California fires to “global warming”. Never mind that the fire was caused by arson, or that the area hadn’t burned in 40-60 years, leading up to a collection of dry dead underbrush which is part of the natural fire cycle. Never mind that La Nina made for a dry couple of years exacerbating the problem. Never mind that we get fires in California about this time every year. No, its the “Age of Megafires”:

Windmills Are Killing Our Birds -- A Commentary

From Wall Street Journal:

One standard for oil companies, another for green energy sources.

On Aug. 13, ExxonMobil pleaded guilty in federal court to killing 85 birds that had come into contact with crude oil or other pollutants in uncovered tanks or waste-water facilities on its properties. The birds were protected by the Migratory Bird Treaty Act, which dates back to 1918. The company agreed to pay $600,000 in fines and fees.

Hydrogen Storage Gets New Hope

Ammonia borane (AB) is a potential hydrogen releasing fuel. In this Los Alamos National Laboratory graphic, the AB would be used on-board the vehicle to run a fuel cell. Once hydrogen is released, the AB could then be regenerated and reused. In the scheme shown, the recycle of dehydrogenated fuel back into AB would take place off-board the vehicle.

From Science Daily:

ScienceDaily (Sep. 7, 2009) — A new method for “recycling” hydrogen-containing fuel materials could open the door to economically viable hydrogen-based vehicles.

In an article appearing in Angewandte Chemie, Los Alamos National Laboratory and University of Alabama researchers working within the U.S. Department of Energy’s Chemical Hydrogen Storage Center of Excellence describe a significant advance in hydrogen storage science.

Hard Labor: How 10 Animals Struggle to Survive

From Live Science:

Many Americans think of Labor Day as merely the end of summer and part of a welcome three-day weekend. Its origin, however, is in celebrating the labor movement and workers' rights. So enjoy the break (if you get one in this modern 24/7 world), but if you think you have it tough, consider the hard labor put in by these 10 creatures, all just to survive.

Google To Remove European Titles From US E-Book Settlement

From The Wall Street Journal:

BRUSSELS (Dow Jones)--Online search giant Google Inc. (GOOG) Monday said it will remove all European books that are still commercially available from a $125 million U.S. settlement with publishers to scan orphaned and out-of-print books in the U.S. and sell them online.

The concessions come given the concerns of European authors and publishers, who don't want the search engine to scan books by European authors, which are still protected by copyrights, without asking their permission.

Islamic Search Engine ImHalal Filters Out Potentially Sinful Material

The ImHalal search engine warns users of potentially illicit words and material on the internet.

From Times Online:

Muslims will be able to surf the internet without the fear of accidentally encountering sinful material after a Dutch company launched the world’s first Islamic search engine.

The ImHalal service works like any other search facility until potentially illicit words are entered, when it rates the search from one to three on its risk of generating “haram” or forbidden material.

Reza Sardeha, founder of AZS Media Group which runs the search engine, said: “The idea grew up when some friends of mine complained that when they searched on Google or Yahoo once in a while they bumped into sexually explicit content.”

Is There a Climate-Change Tipping Point?

NASA / Corbis

From Time Magazine:

Global warming — the very term sounds gentle, like a bath that grows pleasantly hotter under the tap. Many people might assume that's how climate change works too, the globe gradually increasing in temperature until we decide to stop it by cutting our carbon emissions. It's a comforting notion, one that gives us time to gauge the steady impact of warming before taking action.

Breakthrough In Fight Against Diabetes

From The Telegraph:

A gene that controls the way the body responds to the hormone insulin has been identified, marking a breakthrough in the fight against diabetes.

Scientists believe a variation in the gene's DNA promotes insulin resistance, the primary cause of type 2 diabetes. The disease is the most common form of diabetes, affecting around two million people in the UK.

The discovery could lead to new drug treatments that target the genetic fault and prevent the body failing to respond to insulin.

Short-Haired Bumblebee To Be Repopulated In UK

From The Guardian:

Descendants of the lost UK bumblebee will be brought from New Zealand to Dungeness in what could be a landmark repopulation programme.

British conservationists have drawn up plans to repopulate the countryside with a species of bumblebee that was declared extinct here nearly a decade ago.

The short-haired bumblebee officially died out in the UK in 2000, but descendents of the doomed community live on in small pockets of New Zealand, where they were taken to pollinate red clover in the late 19th century.

Nano Printing Goes Large

From Technology Review:

A rolling nanoimprint lithography stamp could be used to print components for displays and solar cells.

A printing technique that could stamp out features just tens of nanometers across at industrial scale is finally moving out of the lab. The new roll-to-roll nanoimprint lithography system could be used to cheaply and efficiently churn out nano-patterned optical films to improve the performance of displays and solar cells.

Nanoimprint lithography uses mechanical force to press out a nanoscale pattern and can make much smaller features than optical lithography, which is reaching its physical limits. The technique was developed as a tool for miniaturizing integrated circuits, and a handful of companies, including Molecular Imprints of Austin, TX, are still developing it for this application.
