Arthur Ashkin, Ph.D. ’52, who won the Nobel Prize in physics in 2018 for pioneering “optical tweezers” that use laser light to capture and manipulate microscopic particles, died Sept. 21 at his home in Rumson, N.J. He was 98.
The superfluid helium-3 has many notable qualities. With its low mass and small atomic size, it remains in a liquid state – and when it transforms to the superfluid state, flowing without resistance – down to absolute zero, or minus 459.67 degrees Fahrenheit. It is a pure system, without any disorder. And it is full of surprises.
As with actors and opera singers, when measuring magnetic fields it helps to have range.
Cornell researchers used an ultrathin graphene “sandwich” to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes in magnetic fields that might otherwise get lost within a larger magnetic background.
Peter McMahon, assistant professor of applied and engineering physics in the College of Engineering, and Brad Ramshaw, the Dick & Dale Reis Johnson Assistant Professor of Physics in the College of Arts and Sciences, have been named CIFAR Azrieli Global Scholars.
Harold A. Scheraga, the George W. and Grace L. Todd Professor Emeritus of Chemistry in the College of Arts and Sciences, who had a profound impact shaping the understanding of protein structure, died Aug. 1 in Ithaca. He was 98.
Like Bigfoot and the Loch Ness monster, critical spin fluctuations in a magnetic system haven’t been captured on film. Unlike the fabled creatures, these fluctuations – which are highly correlated electron spin patterns – do actually exist, but they are too random and turbulent to be seen in real time.
As a first-generation college student whose family – refugees from Indonesia – arrived in Harrisburg, Pennsylvania, when he was only a year old, Malikul Muhamad ’20 credits his teachers and professors with helping him chart a successful course through uncertainty and new experiences.
Cancer cells not only ravage the body – they also compete with each other.
Cornell mathematicians are using game theory to model how this competition could be leveraged, so cancer treatment – which also takes a toll on the patient’s body – might be administered more sparingly, with maximized effect.
Theologians once pondered how many angels could dance on the head of a pin. Not to be outdone, Cornell researchers who build nanoscale electronics have developed microsensors so tiny, they can fit 30,000 on one side of a penny.
Cornell is leading a $77 million effort, beginning April 1, to upgrade the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN).
Cornell structural biologists took a new approach to using a classic method of X-ray analysis to capture something the conventional method had never accounted for: the collective motion of proteins. And they did so by creating software to painstakingly stitch together the scraps of data that are usually disregarded in the process.
