A Fashionable Chemical and Biological Threat Detector-on-a-Ring

Credit: The American Chemical Society First-of-its kind ring sensor can detect chemical and biological threats. Newswise — Wearable sensors are revolutionizing the tech-world, capable of tracking processes in the body, such as heart rates. They’re even becoming fashionable, with many of them sporting sleek, stylish designs. But wearable sensors also can have applications in detecting […]

New Amazon Threat? Deforestation From Mining

New Amazon Threat? Deforestation From Mining

Newswise — Sprawling mining operations in Brazil are destroying much more of the iconic Amazon forest than previously thought, says the first comprehensive study of mining deforestation in the world’s largest tropical rainforest. The research, published in Nature Communications, finds that mining-related forest loss caused roughly 10 percent of all Amazon deforestation between 2005 and 2015, […]

Ophelia shows many hurricanes could reach Europe in the future

Ophelia shows many hurricanes could reach Europe in the future

NOAA/NASA Goddard Rapid Response Team By Michael Marshall The remnants of Hurricane Ophelia have struck the British Isles, causing widespread disruption and damage on Ireland. The cyclone, now downgraded to an extratropical storm, has reportedly led to three deaths. It is unusual for a hurricane to reach western Europe while still at or near hurricane strength. […]

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 […]
