Under certain conditions, it takes less time to cool a hot system than to cool the same system initiated at a lower temperature. This phenomenon – the “Mpemba Effect”, has been observed in a variety of systems, including water, magnetic alloys and carbon nano-tube resonators. So far, no single generic mechanism to explain this counter-intuitive behavior was suggested. Using the theoretical framework of nonequilibrium thermodynamics, we construct a minimal model that describes this behavior and...
A postdoctoral fellowship program has been established for quantum-bio projects at the Kavli Institute of Nanoscience Delft (KIND). KIND Postdoctoral Fellows are high-profile, two-year postdoctoral positions with significant independence and resources. The KIND Postdoctoral Fellows program is designed to attract the best and brightest young researchers in nanoscale science to Delft. Fellows will work in partnership with Delft faculty on a nanoscience project that involves both quantum and biological nanoscience research at KIND. Funds for running budget and travel will be available. ...
The National Academy of Sciences announced today that it has received a $10.5 million gift from The Kavli Foundation to establish the Fred Kavli Endowment Fund, which honors the late physicist, entrepreneur, innovator, business leader, and philanthropist. To recognize Kavli’s generous and unwavering support for science, the auditorium of the historic National Academy of Sciences Building will be renamed the Fred Kavli Auditorium. A portrait of Fred Kavli and a commemorative plaque will be unveiled at the NAS annual meeting, which will take place April 29-May 2....
Implanted medical devices such as left ventricular-assist devices for patients with heart failure or other support systems for patients with respiratory, liver or other end organ disease save lives every day. However, bacteria that form infectious biofilms on those devices, called device-associated infections, not only often sabotage their success but also contribute to the rampant increase in antibiotic resistance currently seen in hospitals....
