Subset of carbon nanotubes poses cancer risk similar to asbestos in mice

Nanotechnology, the science of developing materials containing very small fibers, is having a growing influence on daily life. Now researchers have shown for the first time in mice that long and thin nanomaterials called carbon nanotubes may have the same carcinogenic effect as asbestos: they can induce the formation of mesothelioma. The findings were observed in 10%-25% of the 32 animals included in the study, which has not yet been replicated in humans. The work appears November 6 in Current Biology.

Age-old malaria treatment found to improve nanoparticle delivery to tumors

Physics news

Distinguishing between humans and computers in the game of go

(Phys.org)—By analyzing the statistical features of thousands of go games played by humans and computers, researchers have found that it's surprisingly easy to tell whether a game is being played by a human or by a computer. The results point to fundamental differences in the ways that humans and computers solve problems and may lead to a new kind of Turing test designed to distinguish between the two.

Ultrafast magnetic reversal points the way toward speedy, low-power computer memory

Researchers at UC Berkeley and UC Riverside have developed a new, ultrafast method for electrically controlling magnetism in certain metals, a breakthrough that could lead to greatly increased performance and more energy-efficient computer memory and processing technologies.

Beyond good vibrations: New insights into metamaterial magic

If invisibility cloaks and other gee-whiz apps are ever to move from science fiction to science fact, we'll need to know more about how these weird metamaterials actually work. Michigan Tech researcher Elena Semouchkina has gone back to basics and shed more light on the physics behind the magic.

Physicists develop a device that could provide conclusive evidence for the existence (or not) of non-Abelian anyons

What kinds of 'particles' are allowed by nature? The answer lies in the theory of quantum mechanics, which describes the microscopic world.

A new kind of quantum computer

Quantum mechanics incorporates some very non-intuitive properties of matter. Quantum superposition, for example, allows an atom to be simultaneously in two different states with its spin axis pointed both up and down, or combinations in between. A computer that uses quantum mechanical manipulation of atoms or particles therefore has many more possible options than a conventional one that works with "zeros" and "ones" and has only two choices, called bits. A quantum computer's memory uses instead what are called quantum bits - qubits - and each qubit can be in a superposition of these two states. As a result, theoretical physicists estimate a quantum computer with only about one hundred of these qubits could in principle exceed the computing power of the powerful current classical computers. Building a quantum computer is therefore one of the main technological goals in modern physics and astrophysics.

Researchers develop milestone for ultra-fast communications and computing

A mineral discovered in Russia in the 1830s known as a perovskite holds a key to the next step in ultra-high-speed communications and computing.

Where did those electrons go? Decades-old mystery solved

The concept of "valence" - the ability of a particular atom to combine with other atoms by exchanging electrons - is one of the cornerstones of modern chemistry and solid-state physics.

Antiferromagnetic dysprosium reveals magnetic switching with less energy

Dysprosium is not only the atomic element with the strongest magnetic moments, but it also possesses another interesting property: Its magnetic moments point either all the same direction (ferromagnetism) or are tilted against each other, depending on the temperature. This makes it possible to investigate within a single sample how differently oriented magnetic moments behave when they are excited by an external energy pulse.

The element erbium could pave the way to a quantum internet

If you were to try reciting the periodic table, you might stumble before you got to the rare earth elements.

How much does a kilogram weigh?

The kilogram doesn't weigh a kilogram any more. This sad news was announced during a seminar at CERN on Thursday, 26 October by Professor Klaus von Klitzing, who was awarded the 1985 Nobel Prize in Physics for the discovery of the quantised Hall effect. "We are about to witness a revolutionary change in the way the kilogram is defined," he declared.

Black holes with 'dreadlocks' offer insight into quantum matter

Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with 'dreadlocks' harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. The research is published in Physical Review Letters.

Researchers develop data bus for quantum computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Diffused light shows clear structures

Scientists gain an insight into the fascinating world of atoms and molecules using x-ray microscopes. Ground-breaking research by physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the Deutsches Elektronen Synchrotron (DESY) in Hamburg, and the University of Hamburg has paved the way towards new imaging techniques. The team of scientists have successfully developed and tested a method which is considerably more effective than conventional procedures. The researchers' findings have recently been published in Nature Physics.

Physicists improve vertical stability of superconducting Korean fusion device

A major challenge facing the development of fusion energy is maintaining the ultra-hot plasma that fuels fusion reactions in a steady state, or sustainable, form using superconducting magnetic coils to avoid the tremendous power requirement of copper coils. While superconductors can allow a fusion reactor to operate indefinitely, controlling the plasma with superconductors presents a challenge because engineering constraints limit how quickly such magnetic coils can adjust when compared to copper coils that do not have the same constraints.

Earth news

Cool idea: Magma held in 'cold storage' before giant volcano eruption

Long Valley, California, has long defined the "super-eruption." About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 cubic kilometers of lava and ash spewed out in the kind of volcanic cataclysm we hope never to witness.

Swapping where crops are grown could feed an extra 825 million people

NASA satellite tracks ozone pollution by monitoring its key ingredients

Ozone pollution near Earth's surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. New NASA-funded research has devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to differentiate among three different sets of conditions that lead to its production. These observations may also assist air quality managers in assessing the most effective approaches to emission reduction programs that will improve air quality.

Learning how to direct the activity of Tregs has important implications for improving cancer immunotherapy as well as developing better treatments for autoimmune diseases such as rheumatoid arthritis and type 1 diabetes.

H3N2 mutation in last year's flu vaccine responsible for lowered efficacy

The low efficacy of last year's influenza vaccine can be attributed to a mutation in the H3N2 strain of the virus, a new study reports. Due to the mutation, most people receiving the egg-grown vaccine did not have immunity against H3N2 viruses that circulated last year, leaving the vaccine with only 20 to 30 percent effectiveness. Scott Hensley, PhD, an associate professor of Microbiology, in the Perelman School of Medicine at the University of Pennsylvania, describes his team's findings in the Proceedings of the National Academy of Sciences this week.

Diverse drug-resistant cancer cells share a hidden weakness

Saving neurons may offer new approach for treating Alzheimer's disease

Treatment with a neuroprotective compound that saves brain cells from dying also prevents the development of depression-like behavior and the later onset of memory and learning problems in a rat model of Alzheimer's disease. Although the treatment protects the animals from Alzheimer's-type symptoms, it does not alter the buildup of amyloid plaques and neurofibrillary tangles in the rat brains.

Immune cells mistake heart attacks for viral infections

A study led by Kevin King, a bioengineer and physician at the University of California San Diego, has found that the immune system plays a surprising role in the aftermath of heart attacks. The research could lead to new therapeutic strategies for heart disease.

Researchers discover eight new epilepsy genes

Approximately 30 per cent of patients with epilepsy do not respond to anti-epileptic drugs. In these cases, all neurologists can do is attempt to find the right combination of medication through trial and error. A treatment that could target the root cause of epilepsy is a beacon of hope for these patients. But identifying the cause of the pathology is no easy feat. "There are many genes involved," said Jacques Michaud, pediatrician at CHU Sainte-Justine and Professor of Pediatrics and Neuroscience at the Faculty of Medicine of Université de Montreal. "Each child can have different genetic mutations. Often the clinical symptoms do not clearly reflect the cause of epilepsy, which makes choosing the right treatment more difficult."

A new method accelerates the mapping of genes in the 'Dark Matter' of our DNA

The information in the sequence of the human genome has a paramount importance in biomedical research. However, the value of this information is very limited in absence of a detailed map of the genes encoded in the genome. The genes are the basic biological units responsible for the biological traits of organism. Detailed information already exists, on the genomic regions that contain the genes that code for proteins, but the information about non-coding DNA regions - also known as DNA "dark matter" - lags behind. Here are found poorly-understood genes called "long non-coding RNAs" (lncRNAs), which are amongst the most numerous of all, and have been linked to a variety of diseases.
