(Image: NASA/JPL/Caltech/R. Hurt)

From New Scientist:

Can the rate of past discoveries be used to predict future ones? We may soon find out. Two researchers have used the pace of past exoplanet finds to predict that the first habitable Earth-like planet could turn up in May 2011.

In 1965, Intel co-founder Gordon Moore observed that the number of transistors that fit on a chip doubles about once every two years – a trend now known as Moore's law. Samuel Arbesman of Harvard Medical School in Boston wants to see if scientometrics – the statistical study of science itself – can similarly be used to not only study past progress but also to make predictions.

The Worst Part of GoingTo Space? Your Fingernails Come Off

Oh, It Hurts Some astronauts report losing their fingernails on spacewalks because of bulky gloves that cut off circulation and chafe against their hands. To avoid this inconvenience, a couple astronauts have taken to ripping off their own fingernails before reaching orbit. NASA

From Popular Science:

Did you think drinking your own urine was bad? To truly test whether you have the right stuff, imagine ripping out your own fingernails, on purpose.

A couple of astronauts have done this before going into orbit, because they figure it’s better than losing them inside chafing, unwieldy spacesuit gloves, according to Dava Newman, director of MIT’s technology and policy program and director of the university’s Man Vehicle Lab. Newman, who has studied space-related injuries, told a group of journalists at MIT that some astronauts have reported losing their fingernails during spacewalks. Fingernail trauma and other hand injuries are spacewalkers’ biggest complaint, she said.

The Ultimate Field Guide to Subatomic Particles

From io9:

Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles.

This is, as you might imagine, a pretty big topic, so we're splitting it into (at least) two posts. Today we're going to deal with just the particles that physicists are certain (or, at least, reasonably certain) exist, and then tomorrow we'll get into the even stranger world of particles that have been hypothesized but may or may not actually exist. I've also made a handy cheat sheet listing all the elementary particles and their vital statistics, which you can find here. But to understand what all of that means, you'll really want to read on.

Glacial Armour Lets Mountains Rise High

Ripe for the buzz saw (Image: Egner Photography/iStock)

From New Scientist:

Glaciers limit mountain height by stripping rock off the top – but not always. If conditions are right, glacial ice will protect the rocks beneath to let mountains grow.

The upper reaches of high mountains are covered with snow all year round, allowing glaciers to form. As these rivers of ice move slowly downhill, they wear away the rocks beneath them, meaning that mountains should not grow much beyond the height of their snowline: any rock that is pushed up above this altitude will eventually get worn away by the ice. This is called the buzz-saw hypothesis, because, like superhuman circular saws, the glaciers effectively cut the heads off mountains above a certain height.

From Discovery News:

At 17 feet, the bird's wingspan may exceed that of any other flying animal ever to exist. Size, however, has its drawbacks.

Soaring the Chilean skies 5-10 million years ago, an enormous bony-toothed bird has set the world wingspan record. The bird's wingspan was at least 17 feet, according to scientists.

The measurement is based on well preserved wing bones from the newly named bird species, Pelagornis chilensis, a.k.a. "huge pseudoteeth" from Chile. The animal weighed about 64 pounds and belonged to a group known as pelagornithids -- birds characterized by long, slender beaks bearing many spiny, tooth-like projections.
