The study was a collaboration between scientists in Japan, including at Nagoya University, and colleagues in the US, including from NASA.

Kilonovae: Ambushing the standard candle in its own nest

Gamma-ray bursts (GRBs) are the most luminous and explosive transient phenomena in the universe after the Big Bang. A powerful tool for characterizing and classifying GRBs to allow them to be used as tracers of the expansion history of the universe and to understand their mysterious and debated physical mechanisms has been recently presented by an international team of researchers led by Dr. Maria Dainotti, assistant professor at Jagiellonian University, Poland. The new article, which has been accepted by the Astrophysical Journal, is a statistical analysis of the properties of the mysterious GRBs, aimed at determining the observational properties of GRB subclasses. The article pays particular attention to the GRBs associated with kilonovae.

Research team finds effect of odor on helpfulness in rats

Despite their reputation, rats are surprisingly sociable and actually regularly help each other out with tasks. Researchers at the Universities of Göttingen, Bern and St Andrews have now shown that a rat only has to smell the scent of another rat that is engaged in helpful behavior to increase his or her own helpfulness. This is the first study to show that just the smell of a cooperating individual rat is enough to trigger an altruistic and helpful response in another. The research was published in the Proceedings of the Royal Society B.

Microbes help unlock phosphorus for plant growth

Phosphorus is a necessary nutrient for plants to grow.

T. rex had huge growth spurts, but other dinos grew 'slow and steady'

Tyrannosaurus rex was one of the biggest meat-eating dinosaurs of all time—it measured up to 42 feet long from snout to tail and would have weighed in at around 16,000 pounds. And it wasn't alone—some of its less-well-known cousins could reach nearly the same size. Scientists have previously shown that T. rex got so big by going through a huge teenage growth spurt, but they didn't know if that was true for just tyrannosaurs, just them and their close relatives, or perhaps all big bipedal dinosaurs. By cutting into dinosaur bones and analyzing the growth lines, a team of researchers got their answer: T. rex and its closest relatives had an awkward adolescence during which they got huge, while its more distant cousins in the allosauroid group kept on growing a little bit every year.

The rainforest's most loyal couples: No evidence for extra-pair paternity in coppery titi monkeys

Since methods for genetic paternity analyses were introduced, it has been clear that many pair-living animal species, including humans, do not take partnership fidelity that seriously. In most species, there is some proportion of offspring not sired by their social father. Coppery titi monkeys living in the Amazon lowland rainforest seem to be an exception. Scientists from the German Primate Center (DPZ)—Leibniz Institute for Primate Research in Göttingen could not find evidence for extra-pair paternity in their study population in Peru. Mate choice seems to be so successful that a potential genetic advantage does not outweigh the social costs of infidelity. The study is published in Scientific Reports.

Researchers describe previously unknown mechanism for inducing electron emission in highly oriented pyrolitic graphite

It is something quite common in physics: Electrons leave a certain material, fly away and are then measured. Some materials emit electrons when they are irradiated with light. These electrons are called photoelectrons. In materials research, so-called Auger electrons also play an important role—they can be emitted by atoms if an electron is first removed from one of the inner electron shells. But now scientists at TU Wien (Vienna) have succeeded in explaining a completely different type of electron emission that can occur in carbon materials such as graphite. This electron emission type has been known for about 50 years, but its cause was previously unclear.

Uncovering the hidden side of storms: France's Taranis satellite to launch in November

Sprites, elves, jets… few people know that scientists habitually use such other-worldly words to describe transient luminous events or TLEs, light flashes that occur during active storms just a few tens of kilometers over our heads. Few people also know that storms can act as particle accelerators generating very brief bursts of X-rays and gamma rays. But what are the physical processes and mechanisms behind these phenomena discovered barely 30 years ago? Do they impact the physics and chemistry of the upper atmosphere, the environment or even humans? Such are the questions facing the French Taranis satellite that will be riding aloft during the night of 16 to 17 November atop a Vega launcher from the Guiana Space Center, an all-French mission involving research scientists from CNES, the national scientific research center CNRS, the atomic energy and alternative energies commission CEA and several French universities.

Going beyond the anti-laser may enable long-range wireless power transfer

Ever since Nikola Tesla spewed electricity in all directions with his coil back in 1891, scientists have been thinking up ways to send electrical power through the air. The dream is to charge your phone or laptop, or maybe even a healthcare device such as a pacemaker, without the need for wires and plugs. The tricky bit is getting the electricity to find its intended target, and getting that target to absorb the electricity instead of just reflect it back into the air—all preferably without endangering anyone along the way.

New understanding of mobility paves way for tomorrow's transport systems

In recent years, big data sets from mobile phones have been used to provide increasingly accurate analyses of how we all move between home, work and leisure, holidays and everything else. The strength of basing analyses on mobile phone data is that they provide accurate data on when, how, and how far each individual moves without any particular focus on whether they are passing geographical boundaries along the way—we simply move from one coordinate to another in a system of longitude and latitude.

Air pollution costs Utahns billions annually and shortens life expectancy by two years

Air pollution has been a problem in Utah since before the territory was officially recognized as a state. The mountain valleys of this high elevation region are particularly vulnerable to the buildup of air pollution from vehicles, household heating and power production. Together with high per-capita energy use, this has resulted in periods of poor air quality. However, with so many types of pollution and regional conditions, determining the overall effects of air pollution on Utah's health and economy has been a major challenge. A new study from 23 Utah-based researchers, including five from the University of Utah, sought to do just that.

Large predatory fish thrive on WWII shipwrecks off North Carolina coast

During a 2016 National Oceanic and Atmospheric Administration (NOAA) expedition to explore a pair of World War II shipwrecks that lie off the North Carolina coast, marine scientists ensconced within glass-domed submersibles navigated to the Atlantic Ocean seafloor in the hope of profiling the fish communities residing on the wrecks. Some of the findings of this joint ecological-archaeological undertaking were published this week in the Ecological Society of America's journal Ecosphere. The two ships, a German U-boat and a Nicaraguan freighter, had not been seen by humans since they sank nearly 80 years ago during the Battle of the Atlantic. "These World War II shipwrecks are important historical monuments, but are also valuable habitat for fish," said Katrina Johnson, the paper's first author and a senior at Bates College in Lewiston, Maine.

In the Amazon's 'sand forests,' birds play by different evolutionary rules

Picture the Amazon. You're thinking lush rainforests teeming with animals, right? It turns out, the Amazon Basin contains other less-famous ecosystems that have been under-studied by biologists for years, including patches of habitat growing on white sands. Scientists are starting to turn their attention to these "sand forests" and the animals that live there. In a new study, researchers examined birds from the region and found that unlike birds in the dense rainforest, the white sand birds travel from one habitat patch to another and interbreed. It's a characteristic that could change the way conservationists protect the sand forest birds.
