Nanotechnology news

New approach provides images of single cell with micrometer resolution via contrast based on cell's thermal properties Thermal properties of cells regulate their ability to store, transport or exchange heat with their environment. So gaining control of these properties is of great interest for optimizing cryopreservation—the process of freezing and storing blood or tissues, which is also used when transporting organs for transplants.

Physics news

	New half-meter record for quantum superposition at macroscopic level (Phys.org)—A team of researchers working at Stanford University has extended the record for quantum superposition at the macroscopic level, from 1 to 54 centimeters. In their paper published in the journal Nature, the team describes the experiment they conducted, their results and also discuss what their findings might mean for researchers looking to find the cutoff point between superposition as it applies to macroscopic objects versus those that only exist at the quantum level. Nature has also published an editorial on the work done by the team, describing their experiment and summarizing their results.
	'Millennium physicist' ready to take helm at nuclear center Fabiola Gianotti, who this week takes the helm at CERN, home to world's largest particle accelerator, is seen as a new breed of scientist. Initially trained in arts and literature, she came to physics relatively late. She enjoys cooking, jogging, music and keeping her eye on the news, and notes the importance of being "a citizen of the world."
	Scientists propose a metasurface for the anomalous scattering of visible light A team of scientists from the Moscow Institute of Physics and Technology (MIPT) and the Landau Institute for Theoretical Physics at the Russian Academy of Sciences has proposed a two-dimensional metamaterial composed of silver elements that refracts light in an unusual way. The research has been published on November 18 in Optical Material Express. In the future, these structures may be used to develop compact optical devices, as well as to create an "invisibility cloak."

Earth news

	Global reductions in mercury emissions should lead to billions in economic benefits for US Mercury pollution is a global problem with local consequences: Emissions from coal-fired power plants and other sources travel around the world through the atmosphere, eventually settling in oceans and waterways, where the pollutant gradually accumulates in fish. Consumption of mercury-contaminated seafood leads to increased risk for cardiovascular disease and cognitive impairments.
	Amazon rainforests could transition to savannah-like states in response to climate change, new study predicts By the end of this century, as climate continues to warm, dry seasons could become longer and more intense in the Amazon region. Droughts could become more commonplace. But the fate of the Amazon forest—home to around 300 billion trees, and crucial to the Earth's water and carbon cycle—in this drier future remains largely uncertain.
	Insights into the origins of sodium and other metallic layers in the Earth's upper atmosphere Takuo Tsuda, assistant professor, Graduate School of Informatics and Engineering, discusses recent work. The Earth's atmosphere is critical for the existence of mankind. A close inspection of reveals that the atmosphere consists of several regions: troposphere is where humans live (ca. 0-15 km); stratosphere and thin layer of ozone (ca. 15-50 km) that absorbs ultra-violet radiation; and the mesosphere/ionosphere (ca. 50-100 km) and thermosphere (where aurora occur) (ca. 100-600 km). For reference, the International Space Station orbits at approximately 400 km above the Earth.
	Beijing pollution soars but no red alert Parts of China's capital Beijing suffered air pollution more than 20 times recommended levels on Tuesday, but authorities refrained from issuing the highest smog alert.
	El Nino winter is here, above average precipitation expected For months now, weather forecasters have been talking about a Godzilla El Niño. Even though most New Mexicans have enjoyed a fairly mild fall, make no mistake, an El Niño winter is here. The question now becomes, how much moisture will it generate over the course of the winter months?
	NASA looks at deadly weather over the US NASA's Global Precipitation Measurement or GPM mission core satellite analyzed extreme weather that affected the U.S. over the course of five days.

Craig Kochel and colleagues discuss the geomorphic impact of the flooding caused Tropical Storm Lee in September 2011 on several large watersheds of the Susquehanna River in the Appalachian Plateau region of north-central Pennsylvania. Unlike many Appalachian floods, the physical impacts to channels and floodplains were extensive.
	Week-long Spanish wildfires extinguished as rain comes to rescue After a week-long battle against more than 200 wildfires that ravaged northern Spain, local authorities and rescue services announced Tuesday that long-awaited rainfall had helped extinguish the blazes.

Astronomy & Space news

	Image: Boulders on a Martian landslide The striking feature in this image, acquired by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on March 19, 2014, is a boulder-covered landslide along a canyon wall. Landslides occur when steep slopes fail, sending a mass of soil and rock to flow downhill, leaving behind a scarp at the top of the slope. The mass of material comes to rest when it reaches shallower slopes, forming a lobe of material that ends in a well-defined edge called a toe.
	SOFIA completes busy year, highlights of 2015 2015 was an exciting year for NASA's flying observatory, the Stratospheric Observatory for Infrared Astronomy, or SOFIA. By flying at altitudes of more than 40,000 feet, above more than 99% of the water vapor in Earth's atmosphere, SOFIA can make observations with its 2.5-meter diameter infrared telescope and crew of pilots and scientists that no other current ground or space observatory can.
	Five key findings from 15 years of the International Space Station The International Space Station is the longest-running continuously inhabited human outpost in space – this year it celebrated its 15th anniversary. As the ISS orbits the Earth it is essentially in a state of free fall, counteracting the Earth's gravity and providing an ideal platform for science in space.
	The top 101 astronomical events for 2016 Here it is… our year end look at upcoming events in a sky near you. This is not a top 10 listicle, and not a full-fledged almanac, but hopefully, something special and unique in between. And as always, some of the events listed will be seen by a large swath of humanity, while others grace the hinterlands and may well go unrecorded by human eyes. We'll explain our reasoning for drilling down each category, and give a handy list of resources at the end.
	Birth of high mass stars and the origin of life Takeshi Sakai, Assistant Professor, Graduate School of Informatics and Engineering, discusses recent work. "I am using the Atacama Large Millimeter/Submillimeter Array (ALMA) facilities in Chile to study the formation of stars," says Sakai. "In particular I am looking at 'high-mass' stars formed in clusters that are approximately 10,000 light years from the Earth. High mass stars play an important role in the evolution of galaxies and ultimately hold the secrets of the origins of life on Earth."

These tools can contribute to control strategies aimed at providing energy when it is most needed, in step with market price peaks.
	Snake robot range-sensing control system avoids tail-end collisions Rescue operations at disaster scenes often use robots to avoid further human danger. Modelling robots on snakes can provide better access through narrow paths in rubble, but previous models that control snake robots by the head do not adequately avoid collisions between the body of the robot and surrounding obstacles. Researchers at the University of Electro-Communications and Kyoto University have now demonstrated an improved control system for avoiding collisions along the full length of snake robots.
	Random additions efficiently anonymize large data sets Balancing transparency and freedom of information with the right to privacy lays high demands on data handling methods. So far methods for anonymizing shared data sets have assumed that there is a distinction between details that can be used to identify an individual (quasi-identifiers) and details that are deemed 'sensitive' and private, but this is not always the case. Now Yuichi Sei and Akihiko Ohsuga from the University of Electro- Communications, alongside Takao Takenouchi from NEC Corporation in Japan, have devised an algorithm that efficiently anonymizes data sets without assuming this distinction.
	Movie pirates break records for stolen previews of latest Hollywood movies Hollywood has broken two very different records this holiday season. Star Wars: The Force Awakens has become the first movie to reach US $1 billion in gross sales in just 12 days. This beats the previous record of the movie "Jurassic World" which had the additional benefit of sales from the world's second biggest market, China. Star Wars opens in China in January and so it will likely push its sales to even more astronomical levels.

	Researchers advance software-defined radio technology The field of 'software-defined radio' (SDR) technology, a wireless communications system implemented by means of software on a computer to replicate the work of traditional hardware, has potential in future cognitive radio systems. Advantages of SDRs include the ability to comply with various wireless protocols without hardware modification. It may be possible not only virtualizing the wireless transceiver but also compensating for the instability of the wireless protocol at the receiving end, or launching the wireless transceiver corresponding to the signal automatically.

Chemistry news

	Researchers discover how some organisms process oxalate, a molecule that can harm humans A wide variety of fruits and vegetables contain oxalate. But humans and most other animals lack the ability to metabolize this molecule—that is, to break it down while digesting it. And so for some people, a buildup of oxalate is associated with kidney stones, arthritis, and even kidney failure.
	Video: The chemistry of hangovers It's almost New Year's Eve, and many will be ringing in 2016 with champagne, wine, beer and cocktails. But for those who overindulge, the next day is accompanied by another tradition: the New Year's Day hangover.

Biology news

	Improving accuracy in genomic mapping with time-series data If you already have the sequenced map of an organism's genome but want to look for structural oddities in a sample, you can check the genomic barcode—a series of distances between known, targeted sites—by cutting a DNA sequence at those sites and examining the distance between the cuts. However, if the original map—obtained through next-generation sequencing involving PCR—contains any amplification biases, there is room for systematic error across studies. To remedy this, researchers at the University of Minnesota and BioNano Genomics have improved a nanochannel-based form of mapping by using dynamic time-series data to measure the probability distribution, or how much genetic material separates two labels, based on whether the strands are stretched or compressed.
	ORNL cell-free protein synthesis is potential lifesaver Lives of soldiers and others injured in remote locations could be saved with a cell-free protein synthesis system developed at the Department of Energy's Oak Ridge National Laboratory.

	Researchers study neurology of balancing on two legs Walking on two legs is inherently unstable, meaning that the human central nervous system must work hard to maintain balance. Walking motion is maintained by two control approaches—feedforward control, in which the body anticipates possible disturbances to steady walking, and feedback control, when the body reacts to an unseen disturbance to stay upright. The precise mechanisms underlying these control approaches are not yet fully understood.
	Creating realistic computational models of the cerebellum In spite of gigantic advances in medical science over the last century there are still huge gaps in our knowledge of the inner workings of the human brain. For example, how do people in their eighties still remember sights, sounds, and fragrances from their childhood; what are dreams; and why certain people can master many different languages and others have their hands full with just one? Underscoring the deep interest in uncovering the functions of the brain, multi-billion dollar projects have been launched in the USA, EU, and Japan to address these and much deeper aspects of the brain.

Increased long-term death risk for adolescents hospitalized for adversity-related injury Adolescents discharged from hospitals in England after an admission for violent, drug- or alcohol-related, or self-inflicted injuries have increased risks of subsequent death and emergency re-admission up to a decade later, according to a study published this week in PLOS Medicine. The study, conducted by Annie Herbert at University College London, UK, and colleagues, showed that in England, risks of death after all types of adversity-related injury were higher than after accident-related injury (61% (95% CI 43%-82%) higher in girls and 113% (95% CI 98%-129%) higher in boys).
Clinical research experts comment on the state of their fields In an Editorial published this week in PLOS Medicine, editors ask an international panel of eleven expert researchers and clinicians spanning a range of specialties to answer questions on their field and what developments they hope and expect to see in 2016.
Factors predicting low patient accrual in cancer clinical trials Nearly one in four publicly sponsored cancer clinical trials fail to enroll enough participants to draw valid conclusions about treatments or techniques. Such trials represent a waste of scarce human and economic resources and contribute little to medical knowledge. Although many studies have investigated the perceived barriers to accrual from the patient or provider perspective, very few have taken a trial-level view and asked why certain trials are able to accrue patients faster than expected while others fail to attract even a fraction of the intended number of participants. According to a study published December 29 in the JNCI: Journal of the National Cancer Institute, a number of measurable trial characteristics are predictive of low patient accrual.
Microorganisms in the womb set stage for diseases Researchers review importance of microorganisms that exist in the gut, suggesting perturbation of the environment during pregnancy, delivery and early infancy could impact the developing baby's early microbiome and set the stage for health problems later in life. The term "microbiome" refers to the trillions of organisms we harbor, on our skin and within our respiratory and gastrointestinal tracts.
	Understanding the intermittencies that lurk in smooth movements Apparently smooth continuous movements to trace moving objects harbour jerks. These jerks are absent when there is no object to be traced and so are thought to stem from changes in motor instructions anticipated and fed forward by the brain to compensate for sensorimotor time lags. So far, there is no conclusive evidence that this is the case. Now, Yasuyuki Inoue and Yutaka Sakaguchi at the University of Electro-communications have demonstrated a method for analysing apparently smooth movements that may help to understand their jerky components.
Peru warns against ritual New Year effigy-burning Peru warned the public Tuesday against its popular New Year tradition of burning national hate figures in effigy, saying the smoke poses a cancer risk.
