Phosphorus nutrition can hasten plant and microbe growth in arid, high elevation sites
Glacial retreat in cold, high-altitude ecosystems exposes environments that are extremely sensitive to phosphorus input, new University of Colorado Boulder-led research shows. The finding upends previous ecological assumptions, helps scientists understand plant and microbe responses to climate change and could expand scientists' understanding of the limits to life on Earth.

Scientists discover new magnetic element
A new experimental discovery, led by researchers at the University of Minnesota, demonstrates that the chemical element ruthenium (Ru) is the fourth single element to have unique magnetic properties at room temperature. The discovery could be used to improve sensors, devices in the computer memory and logic industry, or other devices using magnetic materials.

Researchers identify bacteria and viruses ejected from the ocean
Certain types of bacteria and viruses are readily ejected into the atmosphere when waves break; others less so, researchers reported May 22. A team of chemists, oceanographers, microbiologists, geneticists, and pediatric medicine specialists are attempting to understand how far potentially infectious bacteria and viruses can travel and if those that pose the greatest risks to public health are among those most likely to escape the ocean.

Dusty rainfall records reveal new understanding of Earth's long-term climate
Ancient rainfall records stretching 550,000 years into the past may upend scientists' understanding of what controls the Asian summer monsoon and other aspects of the Earth's long-term climate. Milankovitch theory says solar heating of the northernmost part of the globe drives the world's climate swings between ice ages and warmer periods. The new work turns Milankovitch in its head by suggesting climate is driven by differential heating of the Earth's tropical and subtropical regions.

Hot cars can hit life-threatening levels in approximately one hour
Researchers from University of California San Diego School of Medicine and Arizona State University found that if a car is parked in the sun on a summer day, the interior temperature can reach 116 degrees F. and the dashboard may exceed 165 degrees F. in approximately one hour -- the time it can take for a young child trapped in a car to suffer fatal injuries.

Cold production of new seafloor
Magma steadily emerges between oceanic plates. It pushes the plates apart, builds large underwater mountains and forms new seafloor. This is one of the fundamental processes that constantly change the face of the Earth. But there are also times when new seabed is created without any volcanism, by un-roofing mantle material directly at the seafloor. Scientists led by GEOMAR, Germany have published the first estimation based on seismic data on how much seafloor is produced this way.

Microscopy advance reveals unexpected role for water in energy storage material
A material with atomically thin layers of water holds promise for energy storage technologies, and researchers have now discovered that the water is performing a different role than anyone anticipated. The finding was possible due to a new atomic force microscopy method that measures the sub-nanoscale deformation rate in the material in response to changes in the material caused by energy storage.

Matter-antimatter asymmetry may interfere with the detection of neutrinos
From the data collected by the LHCb detector at the Large Hadron Collider, it appears that the particles known as charm mesons and their antimatter counterparts are not produced in perfectly equal proportions. Physicists from Cracow have proposed their own explanation of this phenomenon and presented predictions related to it, about consequences that are particularly interesting for high-energy neutrino astronomy.

Study of Android users: Mobile security messages 20 percent more effective if warnings vary in appearance
Using brain data, eye-tracking data and field-study data, researchers have confirmed something about our interaction with security warnings on computers and phones: the more we see them, the more we tune them out. But they've also found that slight changes to the appearance of warnings help users pay attention to and adhere to warnings 20 percent more of the time.

New theory finds 'traffic jams' in jet stream cause abnormal weather patterns
A study published in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it's exceeded, blockages form that are remarkably similar to traffic jams -- and climate forecasters can use the same math to model them both.

Researchers devise more effective location awareness for the Internet-of-(many)-Things
Anticipating a critical strain on the ability of fifth generation (5G) networks to keep track of a rapidly growing number of mobile devices, engineers at Tufts University have come up with an improved algorithm for localizing and tracking these products that distributes the task among the devices themselves. It is a scalable solution that could meet the demands of a projected 50 billion connected products in the Internet-of-Things by 2020.

'Uniquely human' muscles have been discovered in apes
Muscles believed to be unique to humans have been discovered in several ape species, challenging long-held anthropocentric theories on the origin and evolution of human soft tissues. This questions the view that certain muscles evolved to provide special adaptations for human traits, such as walking on two legs, tool use, and sophisticated vocal communication and facial expressions. The findings highlight that thorough knowledge of ape anatomy is necessary for a better understanding of human evolution.

Researchers build most comprehensive tree of life for malaria parasites
A new study led by the American Museum of Natural History puts forth the most comprehensive tree of life for malaria parasites to date. Among the researchers' findings is that the diverse malaria parasite genus Plasmodium (which includes those species that infect humans) is composed of several distantly related evolutionary lineages, and, from a taxonomic standpoint, many species should be renamed.

First chip-scale broadband optical system that can sense molecules in the mid-IR
Researchers at Columbia Engineering have demonstrated, for the first time, a chip-based dual-comb spectrometer in the mid-infrared range, that requires no moving parts and can acquire spectra in less than 2 microseconds. The system, which consists of two mutually coherent, low-noise, microresonator-based frequency combs spanning 2600 nm to 4100 nm, could lead to the development of a spectroscopy lab-on-a-chip for real-time sensing on the nanosecond time scale.

Chimpanzee calls differ according to context
An important question in the evolution of language is what caused animal calls to diversify and to encode different information. A team of scientists led by Catherine Crockford of the Max Planck Institute for Evolutionary Anthropology found that chimpanzees use the quiet 'hoo' call in three different behavioural contexts -- alert, travel and rest. The need to stay together in low visibility habitat may have facilitated the evolution of call subtypes.

Controlled nano-assembly
DNA, the carrier of genetic information, has become established as a highly useful building material in nanotechnology. One requirement in many applications is the controlled, switchable assembly of nanostructures. In the journal Angewandte Chemie, scientists have now introduced a new strategy for control through altering pH value. It is based on ethylenediamine, which only supports the assembly of DNA components in a neutral to acidic environment -- independent of the base sequences and without metal ions.
