I didn’t see much point in posting a review over Thanksgiving break, so here’s a look back on the past two weeks in science. And quite a bit has happened: The LHC may have discovered a new state of matter (not quite as exciting as a new particle, but important stuff nonetheless). The existence of an arrow of time has been confirmed. [...]

Did the LHC Catch a New Type of Matter: Color-Glass Condensate?

MIT physicists working at the LHC may have discovered a new kind of matter by accident. The existence of this type of matter, called “color-glass condensate,” was proposed shortly before the discovery. The heavy-ion group, led by Gunther Roland, was colliding lead nuclei with protons at near the speed of light and measuring the [...]

The Flow of Time Has Been Confirmed

Up until the the 1960s, physicists believed that time worked the same forward as it did backward. For example, in classical physics, if you reversed the momentum of every particle in the universe, the universe would look exactly like a tape being run in reverse. This of course begs the question: if the laws of physics work the same way [...]

Cause of Type IA Supernovas Unearthed

Supernova SN 2011fe, the supernova involved in the study A special class of supernova, called a Type Ia supernova, has a remarkably consistent brightness (roughly 5 billion times brighter than the sun). This consistency has been used to estimate the distance of galaxies in the universe. It was studies of these supernovas that allowed [...]

Here’s what science has taught us in the past week: First off, you can take a look at my new interview with Cliff Pickover about The Medical Book, and how medical science has (and hasn’t) changed over the years. For the first time ever, the rare decay of a Bs meson into two muons has been observed. For every billion times the decay [...]

Another look back on this week in science: A new study replicates the results of previous research, suggesting that gargling sugar water can temporarily help with self control by activating the motivational parts of the brain. Simulations by researchers at Carnegie suggest special crystals that keep their electrical fields can be used as [...]

How to Have Self Control: Gargle Sugar Water?

2617354171_c98d01ebf8_n
A new study demonstrates that if you gargle sugar water, without even drinking it, this can temporarily help you maintain your self control. Previous studies had suggested the already counterintuitive idea that drinking sugar water could help with self control, but the new study demonstrates that the energy from sugar has nothing to do [...]
