High levels of carcinogenic chemical found in everyday consumer products
Posted by Xavier Rosseel in categories: health, sustainability
If you asked most people about cadmium they’d probably know very little about it. But it is listed among the World Health Organisation’s ten chemicals of major public health concern, alongside substances such as lead and asbestos. As such, it is concerning to see it in such high quantities in so many household products. The health risk depends on how easily the cadmium can flake off or leach out and additional tests performed indicate that this is greatest for enamelled glassware.
High levels of the carcinogenic chemical cadmium can still be found in everyday household products like second-hand plastic toys, drinking glasses, alcoholic beverage bottles, ceramics and artists’ paints, according to new research by the University of Plymouth.
Cadmium was commonly used to give products a bright red, orange or yellow pigment, but over time the decoration on glass can start to flake and the glaze on ceramics fail.

Two Stalagmites Found in Chinese Cave Are a ‘Holy Grail’ for Accurate Radiocarbon Dating
Posted by Ian Hale in category: climatology
Since its inception in the 1950s, radiocarbon dating has proven indispensable to archaeologists and climate scientists, who rely on the technique to accurately date organic compounds. But a good thing just got better, owing to the discovery of two stalagmites in a Chinese cave containing a seamless chronological atmospheric record dating back to the last Ice Age.
An unbroken, high-resolution record of atmospheric carbon-12 and carbon-14 was found in a pair of stalagmites located within Hulu Cave near Nanjing, China, according to new research published today in Science. Because this record extends back to the last glacial period, to around 54,000 years ago, scientists are now equipped with a more accurate standard for use in radiocarbon calibration.

Inside Shenzhen’s race to outdo Silicon Valley
Posted by Klaus Baldauf in category: drones
Every day at around 4 p.m., the creeeek criikkk of stretched packing tape echoes through Huaqiangbei, Shenzhen’s sprawling neighborhood of hardware stores. Shopkeepers package up the day’s sales—selfie sticks, fidget spinners, electric scooters, drones—and by 5, crowds of people are on the move at the rapid pace locals call Shenzhen sudu, or “Shenzhen speed,” carting boxes out on motorcycles, trucks, and—if it’s a light order—zippy balance boards. From Huaqiangbei the boxes are brought to the depots of global logistics companies and loaded onto airplanes and cargo ships. In the latter case they join 24 million metric tons of container cargo going out every month from Shekou harbor—literally “snake’s mouth,” the world’s third-busiest shipping port after Shanghai and Singapore.

Breakthrough ultrasound treatment to reverse dementia moves to human trials
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
An extraordinarily promising new technique using ultrasound to clear the toxic protein clumps thought to cause dementia and Alzheimer’s disease is moving to the first phase of human trials next year. The innovative treatment has proven successful across several animal tests and presents an exciting, drug-free way to potentially battle dementia.

Ford applied noise-cancelling technology to a doghouse, and it’s awesome

Keeping passengers in a vehicle from hearing the noise of a busy road is a problem that many auto manufacturers have attempted to solve over the years. Noise dampening materials can only do so much, but Ford is now working with noise cancelling technologies that aim to actively combat road sounds by cancelling them out.
The company recently applied its new noise-cancelling know-how to a project that has nothing to do with vehicles, but instead focuses on man’s best friend. Ford Europe built a new kind of doghouse that allows canines to rest without worry of loud noises, like fireworks, disturbing them.

Solar Voyager forced to abandon mission
Posted by Genevieve Klien in categories: sustainability, transportation
A car made from waste plastic has been forced to abort its mission to the South Pole because of bad weather.
Solar Voyager was set to be the first solar-powered expedition to reach Antarctica.
But despite it being Antarctica’s summer, unexpected heavy snow has meant progress has been slow, and now the team have had to turn around.

IonQ Quantum Computer Delivers More Processing Power Than Google’s
Posted by Genevieve Klien in categories: computing, quantum physics
IonQ, one of many companies developing a quantum computer, has announced a new trapped ion quantum computer with 79 processing qubits. The company claims this quantum computer should beat Google’s 72-qubit quantum computer, not just in terms of number of qubits, but also in total processing performance.
