The threat of infants being killed by unrelated males is the key driver of monogamy in humans and other primates.
The study by academics from UCL, University of Manchester, University of Oxford and University of Auckland, is the first to reveal this evolutionary pathway for the emergence of pair living. (more…)
New research into the origins of — and structural differences between — wrinkles, creases, and folds could have applications in many fields, from flexible electronic devices to dermatology to flexible sheets that become sticky when stretched. Findings from a Brown University research group appear in Proceedings of the Royal Society A.
PROVIDENCE, R.I. [Brown University] — Engineers from Brown University have mapped out the amounts of compression required to cause wrinkles, creases, and folds to form in rubbery materials. The findings could help engineers control the formation of these structures, which can be useful in designing nanostructured materials for flexible electronic devices or surfaces that require variable adhesion.

It is not unusual for swarms of small earthquakes to precede a volcanic eruption. They can reach a point of such rapid succession that they create a signal called harmonic tremor that resembles sound made by various types of musical instruments, though at frequencies much lower than humans can hear.

Astronomers from the University of Exeter using the NASA/ESA Hubble Space Telescope along with an international team of researchers have, for the first time, determined the true colour of a planet orbiting another star. (more…)
In this episode of “On the Whiteboard,” Editor Pamela Woon goes to a workshop that features 3D printing and finds that with the Windows 8.1 update, it’s as easy as printing a Word document.
REDMOND, Wash. – July 30, 2013 – In this episode of “On the Whiteboard,” Editor Pamela Woon goes to Makerhaus and its 10,000-square-feet of fabrication prototyping – a membership workshop that features 3D printing for things such as jewelry, toys, and virtually anything you can design with 3D software.

Officers of the Indian Forest Service (IFS) arrived on the Yale campus July 21 for a two-week training session on state-of-the-art concepts and practices in forestry and environmental management. The session is part of a partnership between the Global Institute of Sustainable Forestry at Yale, TERI University (The Energy and Resources Institute in India), and the Indira Gandhi National Forest Academy acting under the auspices of the Indian Ministry of Environment and Forests.
The Indian Ministry of Environment and Forests conceived the idea of holding short, intensive training sessions as a way of injecting fresh ideas, tools, and techniques into its forest service. The Yale Global Institute has participated from the beginning of the program, making this the fourth year, and the sixth group of Indian foresters welcomed to campus. (more…)
At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, amoeba-like foraminifera and other tiny creatures, who thrived in large numbers until the productivity ended—as mysteriously as it began—just a few hundred years later.
Researchers have hypothesized that iron sparked this surge of ocean life, but a new study led by Woods Hole Oceanographic Institution (WHOI) scientists and colleagues at the University of Bristol (UK), the University of Bergen (Norway), Williams College and the Lamont Doherty Earth Observatory of Columbia University suggests iron may not have played an important role after all, at least in some settings. The study, published in the journal Nature Geoscience, determines that a different mechanism—a transient “perfect storm” of nutrients and light—spurred life in the post-Ice Age Pacific. Its findings resolve conflicting ideas about the relationship between iron and biological productivity during this time period in the North Pacific—with potential implications for geo-engineering efforts to curb climate change by seeding the ocean with iron.

ANN ARBOR — New findings from NASA’s Curiosity rover provide clues to how Mars lost its original atmosphere, which scientists believe was much thicker than the one left today.
“The beauty of these measurements lies in the fact that these are the first really high-precision measurements of the composition of Mars’ atmosphere,” said Sushil Atreya, professor of atmospheric, oceanic and space sciences at the University of Michigan. (more…)
