Good things, small packages

Binghamton University electronics engineering center charts new directions at ’micro’ and ’nano’ scale

Imagine a diagnostic “pill” that doctors can navigate through your system to collect video and chemical data about what’s going on in your body. Or how about a space age, two-ply, self-assembling organic-inorganic thin film that makes expensive mirrors and lenses such as those used by NASA virtually indestructible.

Each of these items is at the hear

New tools speed drug discovery and disease research

To study the genetic components of disease, researchers rely on mice or other research models in which particular genes are silenced, or turned off. In recent years, researchers discovered that they can selectively silence genes using small pieces of RNA called siRNA (short interfering RNA).

Unfortunately, sorting out which siRNA sequences block expression of which genes has proven to be truly daunting. Researchers at Whitehead Institute, however, recently released for public use a new comp

USC researchers uncover age discrimination in secretory cells

Study featured on cover of the journal Nature

Hormones and neurotransmitters secreted from cells via bubble-like vesicles are released using age-related criteria, with the youngest vesicles getting first shot at releasing their contents, according to research led by a University of Southern California (USC) physiologist. This is a “complete reverse” from what had previously been presumed to be the process behind hormone secretion, notes Robert Chow, M.D., Ph.D., associate professor of

Pulsar Bursts Coming From Beachball-Sized Structures

In a major breakthrough for understanding what one of them calls “the most exotic environment in the Universe,” a team of astronomers has discovered that powerful radio bursts in pulsars are generated by structures as small as a beach ball.

“These are by far the smallest objects ever detected outside our solar system,” said Tim Hankins, leader of the research team, which studied the pulsar at the center of the Crab Nebula, more than 6,000 light-years from Earth. “The small size of these regi

Small Fossil Remembers When Continents Collided

When were the mountains of Wales pushed up?

It was well before the dinosaurs roamed the earth. And it happened in the aftermath of a gigantic continental collision, when England and Wales (then attached to southern Newfoundland) crashed into Scotland (then attached to north America). The muds of the sea floor were converted, then, into the hard grey slates of the Welsh hills.

Until now it has been very hard to tell exactly when these slates were formed, because the miner

Clean water by efficient treatment

The United Nations World Water Development Report: Water for People, Water for Life considers the water in Finland cleanest in the world. The secret is not only in the quality of raw water, but also in the water treatment methods.

The report, published last week, ranked 122 countries based on the quality of their water and their ability and willingness to improve it. Finland also scored the highest number of points on the overall Water Poverty Index which graded 147 countries according to th

Twisting and binding matter waves with photons in a cavity

Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom “recoils” in…

Physicists arrange atoms in extremely close proximity

The technique opens possibilities for exploring exotic states of matter and building new quantum materials. Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the…

Scientists test for quantum nature of gravity

Research at the south pole studied the mysterious quantum structure of space and time. Einstein’s theory of general relativity explains that gravity is caused by a curvature of the directions…
