New software speeds origami structure designs

New software speeds origami structure designs

Researchers have developed a new computer-aided approach that streamlines the design process for origami-based structures, making it easier for engineers and scientists to conceptualize new ideas graphically while simultaneously generating the underlying mathematical data needed to build the structure in the real world. Origami paper folding techniques in recent years have been at the center […]

How to clean up the dirty water Puerto Ricans are drinking

Joe Raedle/Getty By Aylin Woodward It is almost a month since Hurricane Maria devastated Puerto Rico, yet nearly 80 per cent of the island is still without electrical power and more than 30 per cent of people there don’t have access to potable drinking water. The US Environmental Protection Agency reports that some citizens are […]

LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars

LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars

For the first time, scientists have directly detected gravitational waves–ripples in space-time–in addition to light from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been observed in both gravitational waves and light. The discovery was made using the U.S.-based Laser Interferometer Gravitational-Wave Observatory; the Europe-based Virgo […]

It looks like an oxymoron, but Earth optimism is worth a try

It looks like an oxymoron, but Earth optimism is worth a try

Roland Seitre/naturepl.com FIFTY-FIVE years ago last month, Rachel Carson published her seminal book Silent Spring. Its warning that indiscriminate use of pesticides was poisoning the planet is frequently credited with having started the modern environmental movement. What has that movement achieved? Arguably not much. Certainly not enough. Pesticides still abound, we’re in the midst of […]

Published online 9 November 2011 | Nature479, 160-161 (2011) | doi:10.1038/479160a News: Brazil is developing the last great untapped reserve of hydroelectricity, the Amazon basin. Jeff Tollefson When a few hundred demonstrators, mostly from indigenous communities, temporarily occupied the construction site of the Belo Monte dam on Brazil’s Xingu River early on 27 October, workers […]

Tropical tree roots represent an underappreciated carbon pool

Tropical tree roots represent an underappreciated carbon pool

In a unique study of tropical tree roots at the Smithsonian Tropical Research Institute, roots accounted for almost 30 percent of the total biomass of young trees. The six trees in the experiment, Anacardium excelsum (Espave in Spanish), Cedrela odorata, Dalbergia retusa (Cocobolo), Pachira quinata (Cedro Espino), Tabebuia rosea (Roble) and Terminalia amazonia (Amarillo), all […]

Using Complex Carbohydrates to Absorb Nitrates, Phosphorus

Using Complex Carbohydrates to Absorb Nitrates, Phosphorus

Newswise — Brainstorming sessions between a food chemist and a hydrologist at South Dakota State University have produced an innovative, potentially money-saving idea that would put nutrients back in the field. Assistant professors Srinivas Janaswamy of the Department of Dairy and Food Science and Laurent Ahiablame of the Department of Agricultural and Biosystems Engineering will […]
