Building the ultimate light detector

Eric Bonvin is currently working at László Forró's lab at EPFL. A Swiss-American, he was born in the Lausanne area, and grew up in Switzerland, Germany. His summer project aims to develop ultra-sensitive light detectors that can theoretically pick up a single photon. To do this, Bonvin is given the difficult task of combining two of the most exciting materials: Graphene and perovskite.

All-purpose optical method for observing physical, chemical or biological processes at the nanoscale

To gain even deeper insights into the smallest of worlds, the thresholds of microscopy must be expanded further. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Dresden, in cooperation with the Freie Universität Berlin, have succeeded in combining two established measurement techniques for the first time: near-field optical microscopy and ultra-fast spectroscopy. Computer-assisted technology developed especially for this purpose combines the advantages of both methods and suppresses unwanted noise. This makes highly precise filming of dynamic processes at the nanometer scale possible. The results were recently published in the research journal Scientific Reports.

Physics news

Communicating the consensus on climate change

Consider a medical analogy… If you saw 100 doctors about a mole that had appeared on your chest, and only three of them told you that it was benign, the chances are that you would probably do something about it, no matter how much those three doctors told you not to worry and that it would soon go away.

What we need to do to prepare for a nuclear event

As we observe the 70th anniversary of the bombings of Hiroshima and Nagasaki, it may seem like the threat from nuclear weapons has receded. But it hasn't; the threat is actually increasing steadily. This is difficult to face for many people, and this denial also means that we are not very well-prepared for nuclear and radiological events.

Can we stay safe against the threat of ransomware?

The possibility of losing all of your files and photos on your computer is a frightening prospect for most people. So much so, that large numbers of users are choosing to pay the criminals holding them to ransom rather than lose their data. In Australia alone, ransoms totalling AUD $1 million were reported to have been paid in 2014. A willingness to pay may be the reason behind Australia's rise to being the second most targetted country in the world for these types of attacks in the 1st quarter of 2015.

What neuroscience can learn from computer science

What do computers and brains have in common? Computers are made to solve the same problems that brains solve. Computers, however, rely on a drastically different hardware, which makes them good at different kinds of problem solving. For example, computers do much better than brains at chess, while brains do much better than computers at object recognition. A study published in PLOS ONE found that even bumblebee brains are amazingly good at selecting visual images with color, symmetry and spatial frequency properties suggestive of flowers. Despite their differences, computer science and neuroscience often inform each other.

4-D movies capture every jiggle, creating realistic digital avatars

"Everybody jiggles," according to Dr. Michael Black, Director at the Max Planck Institute for Intelligent Systems (MPI-IS) in Tübingen, Germany. "We may not like it, but how we jiggle says a lot about who we are. Our soft tissue (otherwise known as fat and muscle) deforms, wobbles, waves, and bounces as we move. These motions may provide clues about our risk for cardiovascular disease and diabetes. They also make us look real. Digital characters either lack natural soft-tissue motion or require time-consuming animation to make them believable". Now researchers at MPI-IS have captured people and how people jiggle in exacting detail and have created realistic 3D avatars that bring natural body motions to digital characters.

Municipal utilities drive sustainability in smaller cities

Small cities and rural areas lag behind in environmental protection policymaking because they often lack the financial or technical resources needed.

New hydrogel stretches and contracts like a heat-driven muscle

In research published in Nature Materials, a team led by scientists from the RIKEN Center for Emergent Matter Science in Japan has developed a new hydrogel that works like an artificial muscle—quickly stretching and contracting in response to changing temperature. They have also managed to use the polymer to build an L-shaped object that slowly walks forward as the temperature is repeatedly raised and lowered. Hydrogels are polymers that can maintain large quantities of water within their networks. Because of this, they can swell and shrink in response to changes in the environment such as voltage, heat, and acidity. In this sense they are actually similar to the plant cells, which are able to change shape as the amount of water within them changes in response to environmental conditions.

Scientists determine how antibiotic gains cancer-killing sulfur atoms

How spiritual beliefs relate to cancer patients' physical, mental, and social well-being

Research reveals that most individuals with cancer have religious and spiritual beliefs, or derive comfort from religious and spiritual experiences. But what impact does this have on patients' health? Recent analyses of all published studies on the topic—which included more than 44,000 patients—shed new light on the associations of religion and spirituality with cancer patients' mental, social, and physical well-being. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the analyses indicate that religion and spirituality have significant associations with patients' health, but there was wide variability among studies regarding how different dimensions of religion and spirituality relate to different aspects of health.

Patients at risk for blood clots are not receiving recommended treatment

Venous thromboembolism (VTE), encompassing deep-vein thrombosis (DVT), or blood clots in leg veins, and pulmonary embolism (PE), or clots that travel to the lungs, is the most common cause of preventable death in hospital settings. While these clots can be prevented by an approach called VTE prophylaxis, and this reduces mortality by as much as 80%, VTE prophylaxis is not universally prescribed for high-risk patients. In a study in the Canadian Journal of Cardiology, researchers found that even after educating healthcare providers about the need for VTE prophylaxis, significant numbers of patients did not receive the recommended treatment.

More evidence needed to identify best methods to clean hospital rooms, prevent infections

Tray tables, bed rails, light switches, and toilets: All are common vectors for swapping germs between patients and health care workers. While a new systematic overview in this week's Annals of Internal Medicine points to several promising cleaning tactics of these "high-touch surfaces," there's a lack of evidence as to which is the most effective at reducing healthcare-associated infections (HAIs). Few studies measured patient outcomes or focused on newer technologies, and even less compared cleaning tactics against one another—important gaps to fill as the U.S. health care system works to reduce the 75,000 HAI-related deaths that occur annually.

Women having a baby by IVF are at increased risk of reflux disease after birth

Women who give birth to babies conceived by in-vitro fertilisation (IVF) are at increased risk of experiencing long-term symptoms of gastro-oesophageal reflux disease (GORD), according to the results of a study published in the UEG Journal. Researchers in Turkey compared two groups of women who had given birth to their first child at least 1 year earlier and found that those who had had IVF were three-times more likely to be diagnosed with GORD than those who had conceived naturally. No differences in GORD prevalence were reported between the women who had IVF and gave birth to single babies and those who gave birth to twins.

Stepchildren who view former stepparents as family maintain relationships after divorce

Remarriages often combine two families into one stepfamily unit. When that stepfamily unit dissolves after a divorce, little is known about the relationships between former stepparents and stepchildren. Now, researchers in the University of Missouri College of Human Environmental Sciences found stepchildren's views of former stepparents depended on emotional reactions to the divorce, patterns of support or resource exchanges, and parental encouragement or discouragement to continue step-relationships. Whether stepchildren maintained relationships with their former stepparents largely depended on whether stepchildren viewed their former stepparents as family.
