Arming The Immune System Against H1N1

From Technology Review:

Researchers are working to treat pandemic flu by recruiting a patient's own immune cells.

Viruses multiply incredibly quickly once they've infected their victim--so fast that antiviral medications such as Tamiflu are only effective if given during the first few days of an infection. After that, the viral load is just too high for a single drug to fight off. But researchers are working on a treatment for the H1N1 virus (or swine flu) that uses a different approach. Rather than disabling the virus with a drug, they're creating a vaccine that can activate and steer a patient's own immune cells to attack the invader.

Shuttle Atlantis Departs From Space Station

From Space.com:

The space shuttle Atlantis cast off from the International Space Station early Wednesday after almost a week linked to deliver vital spare parts.

The shuttle detached from the orbiting laboratory at 4:53 a.m. EST (0953 GMT), and flew in a circle around the station so that astronauts on the orbiter could snap detailed photographs to check on the state of the outpost.

"It's a pretty exciting thing to do, be able to see the station you were living in again now on the farewell," STS-129 commander Charlie Hobaugh said in a preflight interview. "Just having it gives us a new snapshot in time of the condition of the vehicle at that point."

From CNET News:

If you need more evidence that energy storage is much more than lithium ion batteries, take a look at the latest smart-grid utility storage projects.

The Department of Energy on Tuesday announced that $620 million in stimulus funding is going to 32 smart-grid programs, which will be coupled with another $1 billion in private money. A total of $770 million from government and industry sources in the next few years will go to energy storage, giving a number of storage technologies a dose of real-world experience.

ScienceDaily (Nov. 25, 2009) — A journey that started with a box of bird feet carried three Montana State University graduate students into the gruesome world of raptors and led to their findings being published in a prominent journal.

Normally focused on dinosaurs, the students compared the claws and killing methods of four types of raptors and published a paper about their research in the Nov. 25th issue of PLoS ONE, a scientific journal published online by the Public Library of Science. The birds of prey that were studied live in North America and Europe and include eagles and hawks, owls, osprey and falcons.

Organic Wine-Makers Look to Greener Packaging

There are no bottles in these boxes of wine -- just wine and the plastic pouch that holds it. Boxing instead of bottling wine saves half the shipping weight (and associated carbon emissions) and keeps the product fresher longer. Bota Box

From Scientific American:

More and more wineries offer organic varieties to lower their eco-footprints. It's no surprise that they're looking at their product packaging's environmental impacts, as well.

With more and more wineries offering organic varieties to lower their eco-footprint, it’s no surprise that they’re looking at the environmental impacts of their packaging as well. The making of conventional glass bottles (and the corks that cap them) uses significant quantities of natural resources and generates considerable pollution. According to the U.S. Environmental Protection Agency, the process of manufacturing glass not only contributes its share of greenhouse gas emissions but also generates nitrogen oxides, sulfur dioxide and tiny particulates that can damage lung tissue when breathed in.

Bigger Brains Not Always Smarter

More brains doesn't necessarily equal more smarts, a new comparison of animal noggins reveals.

Tiny insects could be as intelligent as much bigger animals, despite only having a brain the size of a pinhead, researchers argue in the Nov. 17 issue of the journal Current Biology.

The scientists found that past studies suggest larger animals may need bigger brains simply because there is more to control — for example they need to move bigger muscles and therefore need more and bigger nerves to move them, the authors say. But that may not equate to higher thought.

Some 130 years since Thomas Edison's breakthrough with artificial light, nearly a quarter of humanity still lacks electricity, a fact officials here want delegates to the upcoming U.N. climate talks to consider.

Vast swaths of the world also have no access to modern fuels like natural gas, kerosene or propane, relying instead on wood or charcoal as principal sources of energy. Switching to energy sources that are more efficient and less detrimental to human health is a prerequisite for raising billions out of poverty as nations promised to do, U.N. officials point out.

FOR DECADES, NOBODY in the US had seen the bee.

The silver-haired black Epeoloides pilosula was once widespread in New England, often found where native yellow loosestrife plants grew. But as the region’s pastoral landscapes gave way to forests, the bee lost its sunny open home. In 1927 it was spotted in a Needham meadow and then, despite years of searching, not again. By the start of this century, dejected bee lovers were forced to conclude that the insect was likely extinct in the US.

My Comment: For the past few days I have been reading the emails from the Hadley Climatic Research Unit at Britain's University of East Anglia. Anyone who calls himself a scientist would not only find these emails disturbing, but also frightened to see how science can be used to push a political agenda.

Is global warming hoax? .... it is clear from the internal communication among those who say that global warming is publicly .... that privately they believe that it is not the case.

Scientists who knowingly supported this hoax should be named and publicized. Monies that have been taken should be returned. Criminal charges should be considered.

Dumb Code Could Stop Computer Viruses In Their Tracks

From New Scientist:

ON THE day a new computer virus hits the internet there is little that antivirus software can do to stop it until security firms get round to writing and distributing a patch that recognises and kills the virus. Now engineers Simon Wiseman and Richard Oak at the defence technology company Qinetiq's security lab in Malvern, Worcestershire, UK, have come up with an answer to the problem.

Their idea, which they are patenting, is to intercept every file that could possibly hide a virus and add a string of computer code to it that will disable any virus it contains. Their system chiefly targets emailed attachments and adds the extra code to them as they pass through a mailserver. A key feature of the scheme is that no knowledge of the virus itself is needed, so it can deal with new, unrecognised "zero day" viruses as well as older ones.

Why Do Human Testicles Hang Like That?

From Scientific America:

Earlier this year, I wrote a column about evolutionary psychologist Gordon Gallup’s “semen displacement hypothesis,” a convincing hypothesis presenting a very plausible, empirically supported account of the evolution of the peculiarly shaped human penis. In short, Gallup and his colleagues argued that our species’ distinctive phallus, with its bulbous glans and flared coronal ridge, was sculpted by natural selection as a foreign sperm-removal device. As a companion piece to that work on our phallic origins, Gallup, along with Mary Finn and Becky Sammis, have put forth a related hypothesis in this month’s issue of Evolutionary Psychology. This new hypothesis, which the authors call “the activation hypothesis,” sets out to explain the natural origins of the only human body part arguably less attractive than the penis--the testicles.
