PCs are ten, maybe even fifteen, years behind where they should be. That sounds a lot, but actually makes a lot of sense if you remember what PCs were like in 2005 (spoiler: the same as they are now). Bell's Law, a companion to Moore's Law, states that every decade, a new and lower-priced computer class forms that leads to the establishment of a new industry. This hasn't happened. The desktop PC wasn't out-competed by the laptop, and the laptop wasn&a

Power converters are the little-known systems that make electricity so magical. They are what allow us to plug in our computers, lamps and televisions and turn them on in a snap. Converters transform the alternating current (AC) that comes out of wall sockets into the exact level of direct current (

Researchers have demonstrated that stretching shape-memory polymers embedded with clusters of gold nanoparticles alters their plasmon-coupling, giving rise to desirable optical properties. One potential application for the material is a sensor that relies on optical properties to track an object or environment's thermal history.

All my earliest hi-fi memories involve tube amplification: as a young girl, staring at the tubes' glowing filaments and listening to music with my audiophile father. I was mesmerized by the glow of those tubes, too hot to touch, but even more so by the music, which often was classical or opera. How those tubes worked was a mystery to me, but I knew they played a big part in the magic coming from the speakers.

Astronomers have searched the entire Milky Way to identify the safest places to live. It turns out, we're in a pretty good spot.

This spectacular image features spiral galaxy Messier 106 and its diminutive neighbors, as well as a dense field of background galaxies and foreground stars.

Astronomers found a number of baby stars hiding around the center of the Milky Way using the Atacama Large Millimeter/submillimeter Array (ALMA). Previous studies had suggested that the environment there is too harsh to form stars because of the strong tidal forces, strong magnetic fields, high energy particles, and frequent supernova explosions. These findings indicate that star formation is more resilient than researchers thought. These observations suggest there is ubiquitous star formation a

When stars are born, large clouds of gas and dust form that are known as circumstellar discs. Research by Ph.D. candidate Francisca Concha-Ramrez shows that strong radiation from neighboring stars soon evaporates the dust in these discs, which can prevent planet formation at an early stage. Ph.D. defence on 6 April.

Astronomers have investigated orbital and stellar parameters of an eclipsing binary known as 2M06464003+0109157. Results of the study shed more light on the nature of this peculiar system. The findings were presented in a paper published March 18 on the arXiv pre-print repository.

MIT astronomers have discovered new and unusual galactic neighborhoods that previous studies overlooked. Their results, published today, suggest that roughly 1 percent of galaxy clusters look atypical and can be easily misidentified as a single bright galaxy. As researchers launch new cluster-hunting telescopes, they must heed these findings or risk having an incomplete picture of the universe.

In order to enable large-scale hydrogen production using solar energy, particulate photocatalysts are being researched as a simple and cost-effective solution to splitting water into hydrogen and oxygen. It is necessary to develop a photocatalyst that can efficiently use visible light, which accounts for a large part of solar energy, in the water decomposition reaction. Barium tantalum oxynitride (BaTaO2N) is an oxynitride semiconductor material that absorbs visible light and is capable of decom

Kim Janey, a native of Boston’s Roxbury neighborhood, made history this month — becoming the first woman and first Black mayor of Boston, ending a nearly 200-year revolving door of white, male leadership in the city. “Today is a new day,” Janey said at her official swearing-in ceremony at Boston City Hall last Wednesday. "I come to this day with life experience that is different from the men who came before me.”

Nanowires are vital components for future nanoelectronics, sensors, and nanomedicine. To achieve the required complexity, it is necessary to control the position and growth of the metal chains on an atomic level. In the journal Angewandte Chemie, a research team has introduced a novel approach that generates precisely controlled, helical, palladium-DNA systems that mimic the organization of natural base pairs in a double-stranded DNA molecule.

The results of the study show a new type of bi-molecule formed from two nitric oxide (NO) molecules, both in their ground state and in the Rydberg electronic state.

Ideally, a pigment should be resistant to corrosion under light irradiationespecially to UV radiation. It should also retain its white color in the long term. Today, the industry has already achieved all this with zinc sulfide, but the resulting material is not suitable to exploit its other feature of triggering photocatalytic reaction because no charge carriers remain on the particle surface.

Chemists from RUDN University found out that fluorine and fluoroalkyl groups increase the efficiency of catalysts in metathesis reactions that are used in the pharmaceutical industry and polymer chemistry. The team also identified fluorine-containing compounds that can simplify the purification of the catalyst from the reaction product, making it reusable.

Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots' light-producing efficiency. A new study explains why, and the results have broad implications for developing future quantum and photonics technologies where light replaces electrons in computers and fluids in refrigerators, for example.
