"Dumping iron into the sea can bury carbon dioxide for centuries, potentially helping reduce the impact of climate change, according to a major new study. The work shows for the first time that much of the algae that blooms when iron filings are added dies and falls into the deep ocean."

Astronomers have noted the disappearance, over a mere two-year period, of the dust around a young star in the constellation Centaurus. While they have proposed a couple of hypotheses as to what happened, they conveniently overlooked the possibility that somebody is gathering resources.

Columbia University chemist Robert Breslow, former president of American Chemical Society and recipient of National Medal of Science and other honours, recently wrote this article about origins of organic molecules on Earth. It ended with some surprising and peculiar speculation.

One of my worries is that increasingly scarce* energy will ultimately do us in. Every now and then, I come across something that gives me hope.
There are estimates using just the performance of some of the devices under study that 1% of the nickel mined on the planet each year could produce the world's energy requirements at the order of 25% the cost of coal.
I am curious about one line:
The neutrons set up isotope cascades which result in beta decay, heat and transmutations with the heavy electrons converting the beta decay gamma into heat.
Beta decay produces an (anti-)electron and (anti-)neutrino. Anybody know what the gamma is that he's talking about?

I decided to get myself a mechanical keyboard. Though, I probably have used mechanical keyboards in the past many, many times I forgot how they felt, having used mostly laptop keyboards and slim-profile chiclet-style keyboards. It's really amazing the kind difference more tactile feedback can make with something like a keyboard. The sound and the feel of the keys has already improved my typing and has also improved how my hands feel - my fingers don't get as fatigued. The keyboard I bought is considered a gaming keyboard, the Razer BlackWidow. I don't do any gaming, so my whole reason for buying it was for the mechanical keys. I'm happy with it so far, but I also heard that the Das Keyboard is a very good keyboard. I couldn't find it in the store though, only online, and I preferred to test the keyboard before buying.

Reuters reports: "State health officials have added three more names to a growing list of students in this working-class town who are experiencing mysterious tics and twitching...Although the symptoms are typically associated with Tourette Syndrome, that has been ruled out in all but one case, causing fear and confusion among many residents of Le Roy, N.Y., about 50 miles east of Buffalo."

"Daddy, daddy, my friend want to give us this cute baby python! Can we keep it? Can we?"Not that long ago, Florida's Everglades were full of marsh rabbits, foxes, raccoons, opossums, and white-tailed deer. Today, 94% to 99% of all mammals have disappeared as Burmese pythons have taken over this ecosystem.
"Pythons grow up to be 5 metres long and weigh 70 kg. Adult pythons can eat deer or leopards whole."
"Well, if it gets too big, we can just set it loose."

Ketamine hydrochloride, long used for its anaesthetic qualities especially in veterinary medicine, has become known to drug-seekers as Special K:
"Like other drugs of this class such as tiletamine and phencyclidine (PCP), it induces a state referred to as 'dissociative anesthesia' and is used as a recreational drug."Most right-thinking people agree that people shouldn't use recreational drugs, as they might feel good. But recent studies suggest that ketamine can stop severe depression in its tracks, taking effect very quickly while most other depression drugs take weeks to kick in, and thereby perhaps preventing suicides.

More than one hundred years ago, Charles Babbage began thinking about how to make machines that could do math. Ever since, people have been thinking (and arguing) about whether man will ever mechanically replicate himself. Here's a brief rundown of the major avenues of that research, and their possible roadblocks.

Scientists said that stargrazer Comet Lovejoy was plunging Sun-ward and would come within 140,000 km (87,000 miles) of Sun's surface (36% of distance from Earth to Moon). Since Lovejoy was plunging directly into our star's corona (2-million-degree atmosphere), knowledgeable people expected it to vapourise at some point. It didn't, emerging from behind our Sun looking no worse for wear and tear, and can now be expected to survive for at least another few centuries.

"New research suggests that lakes of liquid water could be buried in the icy crust of Europa, a moon of Jupiter. The processes that create the lakes could also provide nutrients crucial for life on Europa, the scientists say."
