Nanotubes Used to Track Movement Inside Cells

Chemical engineers and biophysicists have successfully tracked single molecules inside living cells with carbon nanotubes. Through this new method, they found that cells stir their interiors using the same motor proteins that serve in muscle contraction.

Fields of Thought

Collections-based research involves a wide variety of people interested in vastly different scales of space and time—from population genetics in mice to global climate change to galaxies across the universe.

…To date, no natural history collection has an entire galaxy inside of its collection cabinets. However, for astrophysicists to model the universe, meteorite collections can deliver useful snapshots of the history of our own galaxy — meteorites.fieldmuseum.org/node/8

A primary aim of today’s natural history collections is to offer such glimpses of the past. Those glimpses show us not only what the world was like in the past, but also how researchers in the past looked at the world. It can be hard to know how to bring together all of those scales of space, time, and perspective, but variation itself is a common thread for natural history collections and the collaborators working across them.

Meet the Paleontologists

Meet the paleontologists who helped create the Museum’s new exhibition, “Pterosaurs: Flight in the Age of Dinosaurs,” and learn about the latest cutting-edge technology that researchers are using to study pterosaurs, the flying reptiles that lived from about 220 and 66 million years ago.

Mark Norell, curator in the Museum’s Division of Paleontology, and Alexander Kellner, Associate Professor at the Museu Nacional in Brazil, have led expeditions to the most remote areas of the planet. And yet, discovering bones that have been buried for millions of years is just one aspect of their job.

Paleontology has traditionally combined a number of disciplines, including earth history, geology and biology. Many paleontologists today spend more hours in computer labs than they do in the field. Michael Habib, a neurobiology professor at the University of Southern California who consulted on the exhibition, applies principles of engineering and biology to understand how pterosaurs might have flown and behaved.

Pterosaurs: Flight in the Age of Dinosaurs is on view from April 5, 2014, through January 4, 2015. Learn more about the exhibition at http://www.amnh.org/pterosaurs

Gravitational Field Strength

Paul Andersen explains how the gravitational field strength is directly related to the mass of the object and indirectly related to the square of the distance from the center of mass. The equation for gravitational field strength was discovered by Sir Isaac Newton and contains a gravitational constant.

Solar research hub

A team of solar thermal engineers and scientists at our Energy Centre in Newcastle have used the ample sunlight flooding their solar fields to create what’s called ‘supercritical’ steam — an ultra-hot, ultra-pressurised steam that’s used to drive the world’s most advanced power plant turbines — at the highest levels of temperature and pressure EVER recorded with solar power.
