Understanding the coevolving web of life as a network

Coevolution, which occurs when species interact and adapt to each other, is often studied in the context of pair-wise interactions between mutually beneficial symbiotic partners. But many species have mutualistic interactions with multiple partners, leading to complex networks of interacting species.

Solar eruptions could electrify Martian moons

Powerful solar eruptions could electrically charge areas of the Martian moon Phobos to hundreds of volts, presenting a complex electrical environment that could possibly affect sensitive electronics carried by future robotic explorers, according to a new NASA study. The study also considered electrical charges that could develop as astronauts transit the surface on potential human missions to Phobos.

Bridging the terahertz gap

Researchers are exploring the possibility of using an infrared frequency comb to generate elusive terahertz frequencies. These frequencies -- which lie in the electromagnetic spectrum between radio waves and infrared light -- have long promised to transform communications and sensing but are very challenging to source. By harnessing a recently discovered laser state, researchers have discovered an infrared frequency comb in a quantum cascade laser that offers a new way to generate terahertz frequencies.

MRI may predict neurological outcomes for cardiac arrest survivors

MRI-based measurements of the functional connections in the brain can help predict long-term recovery in patients who suffer neurological disability after cardiac arrest, according to new research.

Arsenic in domestic well water could affect 2 million people in the US

Arsenic in domestic well water could affect 2 million people in the US

Clean drinking water can be easy to take for granted if your home taps into treated water sources. But more than 44 million people in the U.S. get their water from private domestic wells, which are largely unregulated. Of those, a new report estimates that about 2 million people could be exposed to high levels of naturally occurring arsenic in their water.

Researchers working with classicists and computer scientists have developed a method to preserve digital humanities databases. The preservation strategy allows scholars to re-launch a database application in a variety of environments -- from individual computers, to virtual machines, to future web servers -- without compromising its interactive features.

Youth football: How young athletes are exposed to high-magnitude head impacts

Youth football: How young athletes are exposed to high-magnitude head impacts

Researchers examined exposure to high-magnitude head impacts (accelerations greater than 40g) in young athletes, 9 to 12 years of age, during football games and practice drills to determine under what circumstances these impacts occur and how representative practice activities are of game activities with respect to the impacts. This type of information can help coaches and league officials make informed decisions in structuring both practices and games to reduce risks in these young athletes.

Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54 million-year-old sea turtle hatchling. The work adds to the growing body of evidence supporting persistence of original molecules over millions of years and also provides direct evidence that a pigment-based survival trait common to modern sea turtles evolved at least 54 million years ago.
