New Scientist: Muscle lab: Bulk up with the science of bodybuilding.

He found that the production of new muscle proteins was greatest when the men were lifting the relatively light weights — at 30 per cent of their maximum — until they were fatigued, and couldn’t lift any more.”  Wow, that’s going to shake up an industry.

ESO: How Much Mass Makes a Black Hole?

“A magnetar (eso0831) is a type of neutron star with an incredibly strong magnetic field — a million billion times stronger than that of the Earth, which is formed when certain stars undergo supernova explosions. The Westerlund 1 cluster hosts one of the few magnetars known in the Milky Way. Thanks to its home in the cluster, the astronomers were able to make the remarkable deduction that this magnetar must have formed from a star at least 40 times as massive as the Sun.”  And for those as curious as I, the Wikipedia entry for magnetar.

George Washington University Medical Center: Researchers Identify Breast Cancer Culprits.

Because inflammation may drive MTA1, and since inflammation is believed to drive certain forms of cancer, Kumar’s work suggests one possible reason for why worsening cancer progression has been correlated with other inflammation-inducers.

Gizmag: Spray-on film turns windows into solar panels.

Obviously some light has to be absorbed in order to generate power but the windows would just have a slight tinting (though a transmission of only 8-10% is common place for windows in the ‘sun belt’ areas of the world). Conversely the structural material of the building can also be coated with a higher degree of absorption. This could be side panels of the building itself, or even in the form of ‘clip-together’ solar roof tiles.” It’s about time someone came up with an idea like this.

New Scientist: Autism explosion half explained, half still a mystery.

“Researchers have long claimed that changes to the way the condition is diagnosed are the main cause. But now a series of a studies have shown that diagnostic changes alone cannot account for the increase. They suggest that other causes, perhaps environmental factors, are also contributing to the rise in cases.

Eurekalert: Acetaminophen use in adolescents linked to doubled risk of asthma.

There was a significant association between acetaminophen use and risk of asthma and eczema. For medium users the risk of asthma 43 percent higher than non-users; high users had 2.51 times the risk of non-users. Similarly, the risk of rhinoconjunctivitis (allergic nasal congestion) was 38 percent higher for medium users and 2.39 times as great for high users compared to non-users. For eczema, the relative risks were 31 percent and 99 percent respectively.”  And yet it’s been the ‘preferred’ analgesic for kids among physicians, because of the risk of Reye’s Syndrome with aspirin. Geez.

We could count dead bodies — and that certainly is useful — but it doesn’t tell us what’s going to happen to the reproductive fitness of this organism [snip] Whether it’s a clam, a tuna or a dolphin — is the exposure to this oil at that level going to affect whether or not that animal can reproduce? Or will it affect whether or not its offspring can reproduce? That’s something we really don’t know.”  Thank goodness *someone’s* looking.
