2:51 PM | How Much Cosmic Inflation Probably Occurred?
Nothing focuses the mind like a hanging, and nothing focuses the science like an unexpected experimental result. The BICEP2 claimed discovery of gravitational waves in the cosmic microwave background — although we still don’t know whether it will hold up … Continue reading →

7:26 AM | Experimenting with smartgel gelation
Scientists are experimenting with a new method of gelation. They can add nanoparticles or biomolecules with useful pH, chemical, and temperature sensing properties into a liquid, but incorporating those liquids into existing technology proves difficult.

4:22 AM | The amazing, oozing Macrocat
There is a definite disadvantage to working at home.  In some cases, it comes in the form of a four-legged furry creature.  One that wants you to pet it.  While you’re typing. Today that creature was Macrocat.  The following is a series of pictures I took while I was attempting to work. Apparently the keyboard […]

4:00 AM | LHC, prossimo obiettivo le superparticelle
La scoperta della particella di Higgs ha rappresentato una svolta fondamentale per la ricerca nel campo della fisica delle particelle, anche se molti scienziati ritengono che siamo solo all’inizio (post). Infatti, quando il grande collisore adronico (LHC) entrerà in funzione nel 2015, operando ad un livello di energia quasi il doppio rispetto agli esperimenti precedenti, […]

10:17 PM | Two developments in commercial spaceflight this week
NASA plans to turn to private companies for crew transport.  (Image credit: NASA) With tensions between Russia and the West remaining high, NASA is moving ahead with plans to find a homegrown method for delivering astronauts to Earth orbit.  The agency's own Orion capsule, designed to transport crews to asteroids, the Moon, and beyond is still years from completion, so in the interim it will be up to commercial enterprises to be our taxis.  A field that barely […]

7:44 PM | Falaco Solitons: Particles at the Pool
While the season for swimming has already passed in most of the country, it’s still not too late in the year for some physics fun in the pool! If you’ve got a sunny day, a dinner plate, and access to a calm body of water, you can explore one of the coolest (and coolest-sounding) phenomena in fluid dynamics: vortical (or “Falaco”) solitons.If it sounds like I’m making up words here, let’s start with some definitions: a soliton is a kind of wave which moves […]

7:38 PM | How a Planet Can Mess Up a Star's Looks
Note: An earlier version of this article appeared on Peter Edmonds' blog. Recently, beautiful photos of auroras have been in the news. These colorful light shows were generated by solar storms, and provide a vivid demonstration of activity on the Sun affecting the Earth. The pummeling experienced by our home planet is an example of our one-way relationship with the Sun: it can have a noticeable effect on the Earth, but the Earth has a negligible effect on the Sun. Further afield in the galaxy, […]

6:51 PM | Solar cell researchers break the 'electrode barrier'
For decades, polymer scientists and synthetic chemists working to improve the power conversion efficiency of organic solar cells were hampered by the inherent drawbacks of commonly used metal electrodes, including their instability and susceptibility to oxidation. Now for the first time, researchers have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the 'electrode barrier'.

5:37 PM | New insights into the world of quantum materials
Physicists experimentally observed how the anisotropic properties of particles deform the Fermi surface in a quantum gas. The work published in Science provides the basis for future studies on how the geometry of particle interactions may influence the properties of a quantum system.

Big things, small packages Don’t be fooled by the small size of ultracompact dwarf galaxy M60-UCD1 — it harbors a supermassive black hole, according to a study published yesterday in Nature.  The result makes M60-UCD1 (shown in inset above) the smallest known galaxy to contain a supermassive black hole. And the astronomers’ findings could indicate that other ultracompact dwarf galaxies likely contain such gargantuan black holes at their centers. By measuring the motion of […]

4:20 PM | Researchers design an 'artificial nose' to detect DNA differentiation with single nucleotide resolution
This is a method of identification of nucleic acids, with single nucleotide resolution, based on the generation pattern (bar code) inspired by our olfactory system. The differences in trans-membrane transport can be used to generate fluorescence patterns. That allows the differentiation of molecules as DNA or RNA by means of pattern generation and/or recognition protocols.
