A New Twist on Light Speed

June 27, 2002

Glasgow scientists have measured a single photon’s orbital angular momentum for the first time. The research could lead to speeding up optical communications by allowing each photon sent over fiber optic lines to encode multiple bits as quantum orbital states.

Measuring the Orbital Angular Momentum of a Single Photon, Phys. Rev. Lett. 88, 257901 (2002) (June 24, 2002)

A new twist on nanoparticle behavior

September 24, 2008

Drug makers and regulators should consider the effects of nanoparticle size and surface when developing and monitoring therapies using nanoparticles, University College Dublin research suggests.

The researchers found that the “corona” (cloud of proteins and other biomolecules that adheres to a nanoparticle immersed in biological media) changes depending on the size of the nanoparticle and the charge on its surface, which can affect the particles’ therapeutic action in the… read more

A New Type of Atomic Microscope Getting Closer

October 1, 2008

Researchers at the Universidad Autonoma de Madrid have created an ultrasmooth mirror that reflects a beam of helium atoms instead of electrons and could provide the same resolution as existing electron microscopes without damaging or destroying delicate biological samples.

A New View of Our Universe: Only One of Many

October 29, 2002

Some cosmologists imagine universes sprouting from one another in an endless geometric progression. Others imagine island universes floating and even colliding in a fifth dimension.

Some cosmologists say the observable universe could be only a small patch in a much vaster ensemble bred endlessly in a chain of big bangs.

A new way to assemble cells into 3-D microtissues

March 6, 2009

Scientists at Lawrence Berkeley National Laboratory can now control how cells connect with one another in vitro and self-assemble into three-dimensional, multicellular microtissues that could be used in medicine for a range of applications such as skin grafts, bone marrow transplants, or blood substitutes, as well as in basic medical and biological research.

A New Way to Control Weight?

November 29, 2007

University of Missouri-Columbia researchers have found that sitting results in retention of fat (from lipase reduction), lower HDL (good cholesterol), and overall reduction in metabolic rate.

A new way to create ‘building blocks’ for drugs

October 3, 2012

synthetically_useful_byarils

A new way to prepare biaryls — compounds that are essential building blocks in the creation of drugs and many modern materials such as LEDs — using gold as a catalyst is described by University of Bristol researchers in Science.

Gold catalysis is easier, cheaper and more environmentally friendly than current methods that use palladium as a catalyst.

Biaryls, compounds containing two directly connected benzene… read more

A new way to fight cancer: fasting before chemotherapy

April 1, 2008

University of Southern California researchers studying mice found that fasting for two days protected healthy cells against chemotherapy.

The same chemotherapy dose killed half of the normally fed mice and caused lasting weight and energy loss in survivors.

Test tube experiments with human cells confirmed the finding. Starved normal cells go into a “maintenance mode”–extreme resistance to stresses, but tumors don’t stop growing.

A new way to flip bits

July 21, 2003

Physicists in Japan have shown that electric fields could be used to improve the performance of magnetic data storage devices. Hideo Ohno and colleagues at Tohoku University demonstrated that the magnetic field needed to reverse the magnetization in a storage bit can be reduced by applying an electric field. By making it easier to “flip” the magnetization of a material, the new method could have applications in ultrahigh-density information storage… read more

A new way to freeze molecules for quantum computing

March 29, 2013

Chilling molecules to a fraction of a degree above absolute zero, the temperature at which they can be manipulated to store and transmit data in quantum computers, has proven to be a difficult challenge for scientists.

At higher temperatures, molecules rocket around, bouncing into each other and exchanging energy. Any information a scientist attempted to store in such a chaotic system would quickly become gibberish.

A new way to make solar cells thin, efficient and flexible

December 11, 2013

Researchers from the University of Illinois at Urbana-Champaign and the University of Central Florida may be one step closer to making solar cells that operate efficiently on a large scale.

The team found a way to create large sheets of nanotextured silicon micro-cell arrays that hold the promise of making solar cells lightweight, more efficient, bendable, and easy to mass produce.

Nanoimprinting

A New Way to Read Hard Disks

September 11, 2007

Researchers believe that the magneto-electric effect might be key to creating the sensors needed for ultra-high-capacity memory. The design could lead to much thinner and smaller read heads that are suitable for data densities as high as one terabit per square inch, compared to 200 gigabits per square inch now.

A new way to trap light

Could lead to new types of lasers and sensors
July 11, 2013

trapping_light_mit

MIT researchers have discovered a new method to trap light that could find a wide variety of applications.

There are several ways to “trap” a beam of light — usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals.

But the new system, devised through computer modeling and then demonstrated experimentally, pits light waves against light waves:

It sets up… read more

A New Way to Treat Obesity

May 16, 2008

Enteromedics has developed an implantable device that uses electrical signals to block the vagus nerve (which helps regulate digestion) as an alternative to gastric bypass surgery.

Two electrodes are surgically implanted at the top of the stomach to block signals from the vagus nerve and are controlled by a regulator beneath the skin, which can be programmed at a doctor’s office.

Gastric bypass often leads to dramatic weight… read more

A New Web of Trust

January 6, 2009

Many experts are now looking to DNSSEC to solve the problem of web visitors being sent to malicious Web pages.

DNSSEC is a protocol that verifies DNS messages with digital signatures. It will be implemented in the .org and .gov domains initially.
