Department of Uh-Oh, a continuing series, the drone wars have begun

Late last month, a pair of Islamic State fighters in desert camouflage climbed to the top of a river bluff in northern Iraq to demonstrate an important new weapon: a small drone, about six feet wide with swept wings and a small bomb tucked in its fuselage. Show More Summary

Climate science: Predictable ice ages on a chaotic planet

7 hours agoAcademics : Nature

Statistical analysis has revealed a simple rule for the occurrence of warm periods during the Quaternary, whereas on much longer timescales geological data have confirmed that the Solar System is chaotic. See Article p.427& Letter p...

Molecular biology: RNA editing packs a one-two punch

7 hours agoAcademics : Nature

Optimal protein synthesis requires bases in transfer RNAs to be modified. A key modification has been shown to involve an unusual two-step mechanism that entails the sequential activities of two enzymes. See Letter p.494

Astronomy: Earth's seven sisters

7 hours agoAcademics : Nature

Seven small planets whose surfaces could harbour liquid water have been spotted around a nearby dwarf star. If such a configuration is common in planetary systems, our Galaxy could be teeming with Earth-like planets. See Letter p.45...

Scientists decipher the nanoscale architecture of a beetle's shell

(University of Nebraska-Lincoln) Ruiguo Yang, assistant professor of mechanical and materials engineering at the University of Nebraska-Lincoln, and his colleagues found a way to analyze the fibrous nanostructure of a beetle's lightweight but durable shell.

NASA spies Tropical Cyclone 08P's formation

(NASA/Goddard Space Flight Center) NASA's Aqua satellite spotted Tropical Cyclone 08P as it was developing in the South Pacific Ocean. Tropical Cyclone 08P, or 08P formed east of Extra-tropical cyclone Bart.

A simple rule to determine which insolation cycles lead to interglacials

7 hours agoAcademics : Nature

The pacing of glacial–interglacial cycles during the Quaternary period (the past 2.6 million years) is attributed to astronomically driven changes in high-latitude insolation. However, it has not been clear how astronomical forcing translates into the observed sequence of interglacials. Here we show that before one

NASA Finds 7 Earth-Size Planets

For the first time, astronomers have discovered seven Earth-size planets orbiting a nearby star—and these new worlds could hold life, reports the AP. NASA and the Belgian-led research team announced the news Wednesday. This cluster of planets is 40 light-years away in the constellation Aquarius. They circle tightly around...

Seven temperate terrestrial planets around the nearby ultracool dwarf star TRAPPIST-1

7 hours agoAcademics : Nature

One aim of modern astronomy is to detect temperate, Earth-like exoplanets that are well suited for atmospheric characterization. Recently, three Earth-sized planets were detected that transit (that is, pass in front of) a star with a mass just eight per cent that of the Sun, located 12 parsecs away. Show More Summary

Scientists discover seven Earth-sized planets that could hold life

The cluster of planets is less than 40 light-years away in the constellation Aquarius, according to NASA The post Scientists discover seven Earth-sized planets that could hold life appeared first on Macleans.ca.

Theory of chaotic orbital variations confirmed by Cretaceous geological evidence

7 hours agoAcademics : Nature

Variations in the Earth’s orbit and spin vector are a primary control on insolation and climate; their recognition in the geological record has revolutionized our understanding of palaeoclimate dynamics, and has catalysed improvements in the accuracy and precision of the geological timescale.

Editing and methylation at a single site by functionally interdependent activities

7 hours agoAcademics : Nature

Nucleic acids undergo naturally occurring chemical modifications. Over 100 different modifications have been described and every position in the purine and pyrimidine bases can be modified; often the sugar is also modified. Despite recent...Show More Summary

Basis of catalytic assembly of the mitotic checkpoint complex

7 hours agoAcademics : Nature

In mitosis, for each daughter cell to inherit an accurate copy of the genome from the mother cell, sister chromatids in the mother cell must attach to microtubules emanating from opposite poles of the mitotic spindle, a process known as bi-orientation. Show More Summary

Accepting and adapting are keys to sustaining a career after acquired hearing loss

(Oregon State University) For adults who acquire severe hearing loss, accepting and adapting to the loss play key roles in sustaining a career and thriving in the workplace, new research from Oregon State University indicates.

How do polar bears respond to climate change, subsistence hunting?

(University of Washington) A new, two-part project led by the UW's Kristin Laidre aims to explore the interacting effects of climate change and subsistence hunting on polar bears, while also illuminating the cultural value of the species to indigenous peoples and the role they play in conservation.

Researchers uncover brain circuitry central to reward-seeking behavior

(University of North Carolina Health Care) UNC scientists found that as mice learn to associate a particular sound with a rewarding sugary drink, one set of prefrontal neurons becomes more active and promotes reward-seeking behavior while other prefrontal neurons are silenced, and those neurons act like a brake on reward-seeking.
