Experiment opens the door to multi-party quantum communication
2014-03-24
In the world of quantum science, Alice and Bob have been talking to one another for years. Charlie joined the conversation a few years ago, but now with spacelike separation, scientists have measured that their communication occurs faster than the speed of light.
For the first time, physicists at the Institute for Quantum Computing (IQC) at the University of Waterloo have demonstrated the distribution of three entangled photons at three different locations (Alice, Bob and Charlie) several hundreds of metres apart, proving quantum nonlocality for more than two entangled ...

IST Austria president Thomas Henzinger expressed his delight: "This is an extraordinary streak of publications in major journals which once more emphasizes the outstanding ...
Heparin might be the key to prevent prion conversion and disease
2014-03-24
Prions are infectious agents responsible for neurodegenerative diseases such as bovine spongiform encephalitis (commonly known as "mad cow disease") and Creutzfeldt–Jakob disease in humans.
Since the discovery in the 60s that an incurable and fatal disease could be caused by an infectious agent formed by nothing but converted misfolded proteins, the mechanisms responsible for the conversion of a normal prion protein into its infectious counterpart – the scrapie prion – have been relentlessly investigated. Researchers now know that once converted into the scrapie form, ...
p53 cuts off invading cancer cells
2014-03-24
VIDEO:
In the absence of Omi, Ras-transformed tumor cells form invasive lamellipodial protrusions.
Click here for more information.
The tumor suppressor p53 does all it can to prevent oncogenes from transforming normal cells into tumor cells by killing defective cells or causing them to become inactive. Sometimes oncogenes manage to initiate tumor development in the presence of p53, but, even then, the tumor suppressor doesn't give up and focuses its efforts instead on limiting ...
How developing sperm stick to the right path
2014-03-24
The process of producing high-quality, fertile sperm requires many steps. A study in The Journal of Cell Biology shows how the transcription factor p73 promotes this process by regulating the adhesions between developing sperm and their support cells.
The p53 family of transcription factors has an ancient and well-conserved function in protecting reproductive cells. In mammals, for example, p63 promotes the death of eggs and sperm that have sustained DNA damage, and female mice lacking p73 are infertile due to defects in egg development. Male mice lacking p73 are also ...
Radiation therapy and cancer vaccines: Timing is everything
2014-03-24
(PHILADELPHIA) – Radiation therapy fights cancer in more ways than one. Not only does it force cancer cells to self-destruct, but several studies demonstrate that it also activates the immune system to attack tumor cells. This activation can be used to boost current immunotherapies, such as anti-tumor vaccines, to produce better clinical results. What's less clear, however, is exactly how to combine the two therapies to get the best bang for the therapeutic buck.
To address this question, researchers at Thomas Jefferson University tested an experimental cancer vaccine ...
Unfolded proteins collapse when exposed to heat and crowded environments
2014-03-24
Proteins are important molecules in our body and they fulfil a broad range of functions. For instance as enzymes they help to release energy from food and as muscle proteins they assist with motion. As antibodies they are involved in immune defence and as hormone receptors in signal transduction in cells. Until only recently it was assumed that all proteins take on a clearly defined three-dimensional structure – i.e. they fold in order to be able to assume these functions. Surprisingly, it has been shown that many important proteins occur as unfolded coils. Researchers ...
Diabetes drug shows promise in reducing Alzheimer's disease in an experimental model
2014-03-24
(Boston) Researchers from Boston University School of Medicine (BUSM) have found that the diabetic drug, pramlintide, reduces amyloid-beta peptides, a major component of Alzheimer's disease (AD) in the brain and improves learning and memory in two experimental AD models. These findings, which appear online in Molecular Psychiatry, also found AD patients have a lower level of amylin in blood compared to those without this disease. These results may provide a new avenue for both treatment and diagnosis of AD.
AD is a degenerative brain disease associated with severe functional ...
Fair bosses pay a price
2014-03-24
EAST LANSING, Mich. — Bosses who are fair make their workers happier and their companies more productive, but in the end may be burning themselves out.
A new study led by Michigan State University's Russell E. Johnson found the act of carefully monitoring the fairness of workplace decisions wears down supervisors mentally and emotionally.
"Structured, rule-bound fairness, known as procedural justice, is a double-edged sword for managers," said Johnson, assistant professor of management. "While beneficial for their employees and the organization, it's an especially draining ...
The unconscious mind can detect a liar -- even when the conscious mind fails
2014-03-24
When it comes to detecting deceit, your automatic associations may be more accurate than conscious thought in pegging truth-tellers and liars, according to research published in Psychological Science, a journal of the Association for Psychological Science.
The findings suggest that conscious awareness may hinder our ability to detect whether someone is lying, perhaps because we tend to seek out behaviors that are supposedly stereotypical of liars, like averted eyes or fidgeting. But those behaviors may not be all that indicative of an untrustworthy person.
"Our research ...
Leaders are wired to be task-focused or team-builders, but can be both
2014-03-24
What sort of leader are you? Do you think leading is all about a laser-like focus on the task, watching the bottom line and making sure everyone is doing what they should? Or is it about listening to your team, being open to ideas and perspectives, and inspiring them to find their own niche?
Distinctions between a task-oriented leader and a social-emotional leader have filled the pages of academic literature for more than a half-century. But recent research strongly suggests the distinction has a foundation in our brains—which allows us to be either analytical or empathetic, ...

Gene expression signature reveals new way to classify gum disease
2014-03-24
NEW YORK, NY (March 21, 2014) — Researchers at Columbia University Medical Center (CUMC) have devised a new system for classifying periodontal disease based on the genetic signature of affected tissue, rather than on clinical signs and symptoms. The new classification system, the first of its kind, may allow for earlier detection and more individualized treatment of severe periodontitis, before loss of teeth and supportive bone occurs. The findings were published recently in the online edition of the Journal of Dental Research.
Currently, periodontal disease is classified ...
Inherited mutated gene raises lung cancer risk for women, those who never smoked
2014-03-24
DALLAS – March 21, 2014 – People who have an inherited mutation of a certain gene have a high chance of getting lung cancer — higher, even, than heavy smokers with or without the inherited mutation, according to new findings by cancer researchers at UT Southwestern Medical Center. Although both genders have an equal risk of inheriting the mutation, those who develop lung cancer are mostly women and have never smoked, the researchers found.
People with the rare inherited T790M mutation of the epidermal growth factor receptor (EGFR) gene who have never smoked have a one-in-three ...
Researcher: Study on element could change ballgame on radioactive waste
2014-03-24
TALLAHASSEE, Fla. — Groundbreaking work by a team of chemists on a fringe element of the periodic table could change how the world stores radioactive waste and recycles fuel.
The element is called californium — Cf if you're looking at the Periodic Table of Elements — and it's what Florida State Professor Thomas Albrecht-Schmitt, the lead researcher on the project, calls "wicked stuff."
In carefully choreographed experiments, Albrecht-Schmitt and his colleagues found that californium had amazing abilities to bond and separate other materials. They also found it was extremely ...
Nasal spray delivers new type of depression treatment
2014-03-24
(Toronto) March 24, 2014 – A nasal spray that delivers a peptide to treat depression holds promise as a potential alternative therapeutic approach, research from the Centre for Addiction and Mental Health (CAMH) shows.
The study, led by CAMH's Dr. Fang Liu, is published online in Neuropsychopharmacology.
In a previous study published in Nature Medicine in 2010, Dr. Liu developed a protein peptide that provided a highly targeted approach to treating depression that she hopes will have minimal side effects. The peptide was just as effective in relieving symptoms when ...
Life hots up for British birds
2014-03-24
Climate change may be bad news for billions, but scientists at the University of Sheffield have discovered one unlikely winner – a tiny British bird, the long-tailed tit.
Like other small animals that live for only two or three years, these birds had until now been thought to die in large numbers during cold winters. But new research suggests that warm weather during spring instead holds the key to their survival.
The findings come from a 20-year study of long-tailed tits run by Professor Ben Hatchwell at the Department of Animal and Plant Sciences. The recent work ...
Biased sex ratios predict more promiscuity, polygamy and divorce in birds
2014-03-24
Birds in female-dominated populations are more likely to ditch and 'divorce' their mates while promiscuity increases in predominantly male environments, according to new research.
A joint study by the University of Sheffield and the University of Bath gives the first conclusive proof that rates of divorce and infidelity in birds are affected by the adult sex ratio of the population they live in – a theory previously discounted by biologists.
The study, which examined the pair bonding and mating behaviour of 197 different species of bird, found the divorce rate was higher ...
Recovering valuable substances from wastewater
2014-03-24
Not only plants, but also humans and animals need phosphorus, which is a building block of DNA. Many biological processes in our body can only take place if phosphorus atoms are also present. But farmers and industrial enterprises use so much of this element that soil is over-fertilized and waterways are contaminated.
This is where the experts of the German Phosphorus Platform DPP come in. As they have made it their aim to recover the phosphorus from the water, on the one hand in order to protect the environment and on the other to reutilize this valuable raw material ...
Researchers grow carbon nanofibers using ambient air, without toxic ammonia
2014-03-24
Researchers from North Carolina State University have demonstrated that vertically aligned carbon nanofibers (VACNFs) can be manufactured using ambient air, making the manufacturing process safer and less expensive. VACNFs hold promise for use in gene-delivery tools, sensors, batteries and other technologies.
Conventional techniques for creating VACNFs rely on the use of ammonia gas, which is toxic. And while ammonia gas is not expensive, it's not free.
"This discovery makes VACNF manufacture safer and cheaper, because you don't need to account for the risks and costs ...
Mice give ticks a free lunch
2014-03-24
(Millbrook, NY) People living in northern and central parts of the U.S. are more likely to contract Lyme disease and other tick-borne ailments when white-footed mice are abundant. Mice are effective at transferring disease-causing pathogens to feeding ticks. And, according to an in-press paper in the journal Ecology, these "super hosts" appear indifferent to larval tick infestations.
Drawing on 16 years of field research performed at the Cary Institute of Ecosystem Studies in Millbrook, New York, the paper found that white-footed mice with hundreds of larval ticks ...
