In Slate, Daniel Riley reviews the case for cockroaches surviving a nuclear holocaust. Will cockroaches really inherit post-apocalyptic earth? “…Studies over the last half-decade, such as those conducted by the United Nations Scientific Committee on the Effects of Atomic Radiation, have found that these “other insects” are more likely to reign in the age after humans; the cockroach might, in fact, be one of the first bugs to go. More recently, the television show MythBusters tested the effects of radiation on several kinds of insects and discovered that tiny flour beetles were the hardiest—with some surviving a dose of 100,000 rads…”

Biblical text-writing may have poisoned monks
By Jennifer Viegas, Discovery News. Medieval bones from six different Danish cemeteries reveal that monks who wrote Biblical texts and other religious materials may have been exposed to toxic mercury, which was used to formulate just one of their ink colors: red. The study, which will be published in the August issue of the Journal of Archaeological Science, also describes a previously undocumented disease, called FOS, which was like leprosy and caused skull lesions…scientists believe the monks were either contaminated while preparing and administering medicines, or while writing the artistic letters of incunabula, or pre-1500 A.D. books…

New species, originally uploaded by Koosama.

The Top Ten New Species compiled by the International Institute for Species Exploration includes the Mindoro fruit bat at number six.

Name: Styloctenium mindorensis
How it made the Top 10: This large and charismatic fruit bat species is known only from the Philippine island of Mindoro. It is only the second known species in the genus; the other species is known only from the Indonesian island of Sulawesi and nearby Togian Islands, and was originally discovered (and named after) Alfred Russell Wallace. Wallace was a colleague of Charles Darwin and coauthor of their famous paper On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection. Among other important contributions, he noted the distinctive faunal break separating Asian and Australian biotas, which is now known as Wallace’s Line. Ironically, the new species occurs on the west side of Wallace’s Line whereas its sister species is on the east side. The new species is threatened by habitat loss and hunting. Its discovery highlights an increasing understanding of endemism on Mindoro, and the need for species exploration and conservation.

There must be hundreds of undiscovered species in the Philippines. Due to depredations on their natural habitats, many of them will die out before they are discovered.

A group has filed suit against the CERN Large Hadron Collider. Among other doomsday scenarios, they cite the possibility that when the LHC is turned on, it will create black holes that will swallow up matter and suck up the earth.

This reminds me of our third-year science project at Pisay. My groupmates did all the work because it was a continuation of their second-year  project. It was a prototype for a machine that would harness energy from water, and it looked like a small windmill. Or it may have been a small hadron collider–I wasn’t paying attention, and now I regret it.

Some teachers came round to grade the projects. One teacher listened to the presentation with great interest, then asked, “But if you generate all that heat from the ocean, won’t the ocean freeze over?” This was the same teacher, by the way, who posed this question on an exam: China is opposite the US on the globe. If the entire population of China were to jump a foot in the air at the exact same instant, will the impact of their landing propel the population of the US into outer space? I’m sorry that I wasn’t in his physics class.

from Scientific American News: You’ve given up your fair share of sleep—will you ever feel rested again? By Molly Webster

“Let’s do some sleep math. You lost two hours of sleep every night last week because of a big project due on Friday. On Saturday and Sunday, you slept in, getting four extra hours. Come Monday morning, you were feeling so bright-eyed, you only had one cup of coffee, instead of your usual two. But don’t be duped by your apparent vim and vigor: You’re still carrying around a heavy load of sleepiness, or what experts call “sleep debt”—in this case something like six hours, almost a full nights’ sleep. Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get. It’s a deficit that grows every time we skim some extra minutes off our nightly slumber. “People accumulate sleep debt surreptitiously,” says psychiatrist William C. Dement, founder of the Stanford University Sleep Clinic. Studies show that such short-term sleep deprivation leads to a foggy brain, worsened vision, impaired driving, and trouble remembering. Long-term effects include obesity, insulin resistance, and heart disease.

“The good news is that, like all debt, with some work, sleep debt can be repaid—though it won’t happen in one extended snooze marathon. Tacking on an extra hour or two of sleep a night is the way to catch up. For the chronically sleep deprived, take it easy for a few months to get back into a natural sleep pattern, says Lawrence J. Epstein, medical director of the Harvard-affiliated Sleep HealthCenters.

“Go to bed when you are tired, and allow your body to wake you in the morning (no alarm clock allowed). You may find yourself catatonic in the beginning of the recovery cycle: Expect to bank upward of ten hours shut-eye per night. As the days pass, however, the amount of time sleeping will gradually decrease. For recovery sleep, both the hours slept and the intensity of the sleep are important. Some of your most refreshing sleep occurs during deep sleep. Although such sleep’s true effects are still being studied, it is generally considered a restorative period for the brain. And when you sleep more hours, you allow your brain to spend more time in this rejuvenating period.

“So earn back that lost sleep—and follow the dictates of your innate sleep needs. You’ll feel better. “When you put away sleep debt, you become superhuman,” says Stanford’s Dement, talking about the improved mental and physical capabilities that come with being well rested. Finally, a scientific reason to sleep in on Saturday.”

Ha! The secret of my megalomania: 9 hours of sleep a day. When I had insomnia for a month last year it drove me bonkers. I love that the sleep expert is named Doctor Dement.

Physicists postulate the existence of an invisible form of matter which does not shine or reflect light, which accounts for 90 percent of the mass of the universe. Its huge gravitational pull is believed to hold galaxies together. They call it “dark matter”. Now scientists from the University of Rome announce that they’ve discovered dark matter underneath a mountain in Abruzzo.

Apparently the safest way to clean your ears is with your pinkie. How do you get the gunk out? (True, the gunk is probably imaginary.) And what if you have really long pinkie fingernails like bus conductors?

According to this report, a guy in Quebec died after puncturing his eardrum with a cotton swab. 

I’ve been told that cotton buds are dangerous, but I can’t not use them to clean my ears, I would feel icky if I didn’t. Same way I’ve been told that you’re not supposed to shampoo everyday (In Manila?! Are you kidding?!). My scalp itches just to think about it.

You know Last Song Syndrome, where the last song you hear keeps playing in your head and you can’t make it stop? Well I often have First Song Syndrome—I wake up and there’s a song already playing in my head and it just keeps on going. It is usually a song I have not heard in a long time. Days later, I hear that same song being played somewhere—in a restaurant, over the end credits of a movie, that sort of thing. Could be just coincidence, yes, but I’m inclined to think otherwise. I’m from the school of “Everything means something, the refusal to say anything means something, nothing is something.” (See the Coen Brothers, below.)

Sometimes I remember conversations I haven’t had yet. For instance, I distinctly remember Chus telling me that Myrza (of Marie-Claire) had won a Palanca for short story. He ran into her, and she told him the good news. (This would be in August 2006.) I remember which restaurant we had this conversation in (Segafredo Greenbelt, now closed), where we were seated (by the window), and what time it was (around 6.30pm). Weeks later, I told Chus I was gatecrashing the awards dinner the next day (September 1), and I’d probably see Myrza.

Why, Chus asked, Did she win? Of course she did, I said, You told me. No I didn’t, he said, I didn’t know she’d won. We spent the next 15 minutes arguing over who said what. Finally Chus called Myrza and asked her if she’d won a Palanca.

Myrza said, No, I haven’t heard from them. Chus said, Maybe you should call their office to make sure. Meanwhile I’m sitting there thinking, Did I imagine this? Am I going bonkers? But I’m certain that Chus told me that Myrza had told him. There was no one else I could’ve gotten the news from—I wasn’t privy to the judging process and I’m not in with the awards people.

The following morning Chus called me. Myrza had called the Palanca office, he said, and it turns out she did win a prize! (The guard in her building put the letter in a drawer and forgot it.) So the information I “remembered” was correct, except that it was delivered backwards. Weird, but according to Special Relativity, everything that will happen has already happened anyway.

Back to FSS. I woke up this morning and “Jacksons, Monk and Rowe” by Elvis Costello and The Brodsky Quartet was playing in my head, loud and clear. It’s a very pretty song about divorce, not likely to have been blaring out of a passing jeep, not on the typical radio playlist. It’s on my iPod but I haven’t listened to it in a long time. But there are worse things to have in your head.

From ScienceNOW Daily News: “Talk about “gaydar.” In just a fraction of a second, people can accurately judge the sexual orientation of other individuals by glancing at their faces, according to new research. The finding builds on the growing theory that the subconscious mind detects and probably guides much more of human behavior than is realized.”

Romantic attraction works just as fast. You CAN tell in milliseconds whether you are likely to have a thing with someone. Seems irrational not to mention unfair, but it’s true. From empirical evidence collected over the years, I’ve concluded that if there is no instantaneous attraction/spontaneous combustion between two individuals, it’s not going to work. But that’s just me.

Here’s a Straight Dope classic: “How does one suck in a piece of spaghetti? Think about it. How one sucks milk through a straw is easy. The lowered pressure in the mouth due to sucking causes the air pressure over the milk to force the liquid up. But if one pushes on the end of a piece of spaghetti it just buckles. The mouth is closed and sealed over the sides of the spaghetti, so passing air doesn’t drag it along. Somehow the air very close to the mouth must obliquely communicate a force along the length. . .” It’s more complicated than you think.

“Recently, though, anthropologists have subtly revised the view that the invention of agriculture was a fall from grace. They have found the serpent in hunter-gatherer Eden, the savage in the noble savage. Maybe it was not an 80,000-year camping holiday after all. . .”

Is constant violence a modern pathology, or is it the natural state?

Is this surfer dude the next Einstein?

From New Scientist: “GARRETT LISI is an unlikely individual to be staking a claim for a theory of everything. He has no university affiliation and spends most of the year surfing in Hawaii. In winter, he heads to the mountains near Lake Tahoe, California, to teach snowboarding. Until recently, physics was not much more than a hobby.

“That hasn’t stopped some leading physicists sitting up and taking notice after Lisi made his theory public on the physics pre-print archive this week (www.arxiv.org/abs/0711.0770). By analysing the most elegant and intricate pattern known to mathematics, Lisi has uncovered a relationship underlying all the universe’s particles and forces, including gravity - or so he hopes. Lee Smolin at the Perimeter Institute for Theoretical Physics (PI) in Waterloo, Ontario, Canada, describes Lisi’s work as “fabulous”. “It is one of the most compelling unification models I’ve seen in many, many years,” he says.”

Gnarly. I keep thinking of Sean Penn as Jeff Spiccoli.
