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."

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 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.

Expanded regimens associated with improved treatment response in MDR-TB

Treating multidrug-resistant tuberculosis (MDR TB) with regimens that include a greater number of drugs may improve outcomes, and baseline drug susceptibility testing (DST) could identify drugs with the greatest likelihood of success, according to a paper published this week in PLOS Medicine. The prospective cohort study, conducted by Peter Cegielski of the Centers for Disease Control, Atlanta, Georgia, and colleagues, used information on regimen composition, baseline DST, and time to sputum conversion from 1,137 adults with MDR TB, from nine countries.

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.

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.
