The Lead

The birth of topological spintronics

July 24, 2014 | News | Comments

Research led by Penn State Univ. and Cornell Univ. physicists is studying "spintorque" in devices that combine a standard magnetic material with a new material known as a topological insulator. The new insulator, which is made of bismuth selenide and operates at room temperature, overcomes one of the key challenges to developing a spintronics technology based on spin-orbit coupling.

Laser experiment reveals liquid-like motion of atoms within an ultra-cold cluster

July 25, 2014 5:11 pm | News | Comments

A new study by researchers in the U.K. used a new laser technique to examine in rich detail the structure and internal atomic motion of a small cluster containing an acetylene molecule and a single helium atom. The insight into this tiny structure could help unlock the potential to create new materials using nanosized “building blocks”.

Super-strong superconducting magnet achieves world record current

July 25, 2014 4:38 pm | News | Comments

Using a new type of large-scale magnet conductor, scientists in Japan have recently achieved an electrical current of 100,000 A, a world record. The conductor, which was built using yttrium-based high-temperature superconducting tapes for high mechanical strength, is a prototype for using in a future fusion reactor.

Nanoparticle “alarm clock” may awaken immune systems put to sleep by cancer

July 25, 2014 3:09 pm | News | Comments

Cancerous tumors protect themselves by tricking the immune system into accepting everything as normal, even while cancer cells are dividing and spreading. One pioneering approach to combat this effect is to use nanoparticles to jumpstart the body's ability to fight tumors. Recent combines these therapeutic nanoparticles with heat to stimulate the immune system.

High-performance, Multi-position Reaction Block

July 25, 2014 8:44 am | Product Releases | Comments

The DrySyn MULTI from Asynt converts standard hotplate stirrers into high-performance reaction blocks accommodating three round-bottomed flasks or up to 12 reactions in tubes or vials. The DrySyn MULTI's combination of flexibility, productive performance and safety is suitable in R&D departments for parallel synthesis as well as in teaching and open-access laboratories, where a single compact reaction station can provide heating facilities for several users.

HEMCO Corp. offers fume hood exhaust blowers, ducting and components, HEPA and carbon filtration, fume scrubbers and manifold systems. Fume hood blowers are designed to exhaust corrosive fumes, humid or polluted air, gases and odors. These blowers are in coated steel or PVC, in standard or explosion proof models.

Study reveals new characteristics of complex oxide surfaces

July 25, 2014 8:25 am | by Morgan McCorkle, Oak Ridge National Laboratory | News | Comments

A novel combination of microscopy and data processing has given researchers at Oak Ridge National Laboratory (ORNL) an unprecedented look at the surface of a material known for its unusual physical and electrochemical properties. The research team led by ORNL’s Zheng Gai examined how oxygen affects the surface of a perovskite manganite, a complex material that exhibits dramatic magnetic and electronic behavior.

Molecule could lead to new way to repair tendons

July 25, 2014 8:15 am | by Dan Krotz, Lawrence Berkeley National Laboratory | News | Comments

It’s an all-too familiar scenario for many people. You sprain your ankle or twist your knee. If you’re an adult, the initial pain is followed by a long road of recovery, with no promise that the torn ligament or tendon will ever regain its full strength. That’s because tendon and ligament cells in adults produce little collagen, the fibrous protein that is used to build new tendon and ligament tissue.

Collecting just the right data

July 25, 2014 7:56 am | by Larry Hardesty, MIT News Office | News | Comments

Much artificial intelligence research addresses the problem of making predictions based on large data sets. An obvious example is the recommendation engines at retail sites like Amazon and Netflix. But some types of data are harder to collect than online click histories. And in other applications there may just not be enough time to crunch all the available data.

Researchers discover new way to determine cancer risk of chemicals

July 25, 2014 7:00 am | News | Comments

A new study has shown that it is possible to predict long-term cancer risk from a chemical exposure by measuring the short-term effects of that same exposure. The findings could make it possible to develop simpler and cheaper tests to screen chemicals for their potential cancer causing risk.

Just 8.2% of our DNA is “functional”

July 25, 2014 6:59 am | News | Comments

According to recently published research, scientists in the U.K. say that just 8.2% of human DNA is likely to be doing something important, or “functional”. This figure is very different from one given in 2012, when some scientists involved in the ENCODE (Encyclopedia of DNA Elements) project stated that 80% of our genome has some biochemical function.

Four billion-year-old chemistry in cells today

July 25, 2014 6:58 am | News | Comments

The primordial soup theory suggests that life began in a pond or ocean as a result of the combination of metals, gases from the atmosphere and some form of energy, such as a lightning strike, to make the building blocks of proteins which would then evolve into all species. New research shows how mitochondria in cells continue to perform similar reactions in our bodies today.

The microbes make the sake brewery

July 25, 2014 6:56 am | News | Comments

According to recent research that marks the first time investigators have taken a microbial census of a sake brewery, the microbial populations found on surfaces in the facility resemble those found in the product, creating the final flavor. This means a sake brewery has its own microbial terroir.

Antioxidant biomaterial promotes healing

July 25, 2014 6:55 am | News | Comments

When a foreign material like a medical device or surgical implant is put inside the human body, the body usually reacts negatively. For the first time ever, researchers at Northwestern Univ. have created a biodegradable biomaterial that is inherently antioxidant. The material can be used to create elastomers, liquids that turn into gels, or solids for building devices that are more compatible with cells and tissues.

Biologist warns of early stages of Earth’s sixth mass extinction event

July 25, 2014 6:54 am | by Bjorn Carey, Stanford Univ. | News | Comments

Stanford Univ. biology Prof. Rodolfo Dirzo and his colleagues are warning that "defaunation" could have harmful downstream effects on human health. The planet's current biodiversity, the product of 3.5 billion years of evolutionary trial and error, is the highest in the history of life. But, Dirzo says, this may be reaching a tipping point.

New approach helps form non-equilibrium structures

July 25, 2014 6:49 am | News | Comments

Scientists at Northwestern Univ. have developed a new technique for creating non-equilibrium systems, which experience constant changes in energy and phases, such as temperature fluctuations, freezing and melting, or movement. The method, which involves injecting energy through oscillations to force particles to self-assemble under non-equilibrium conditions, should help us understand the fundamentals of this mysterious topic.
