Cause of cancer is written into DNA of tumours, scientists find, creating a ‘black box’ for origin of disease

Posted by in categories: biotech/medical, sustainability

The cause of cancer is written into the DNA of tumours, scientists have discovered, in a breakthrough which could finally show how much disease is attributable to factors like air pollution or pesticides.

Until now the roots of many cancers have proved elusive, with doctors unable to tease out the impact of a myriad of carcinogenic causes which people encounter everyday.

Even with lung cancer, it is not known just how much can be attributed to smoking and how much could be linked to other factors, such as living by a busy road, or inhaling pollutants at work.

Neutral Zinc-air battery with cathode NiCo/C-N shows outstanding performance

Posted by in categories: bioengineering, energy, sustainability

In a paper to be published in the forthcoming issue in NANO, a team of researchers from the School of Chemistry and Chemical Engineering at Hunan University of Science and Technology have proposed a novel strategy for the synthesis of non-precious metal catalysts in zinc-air batteries that do not compromise its electroactivity, affordability and stability.

As a green and sustainable energy generator, zinc-air battery has attracted great attention from researchers due to its high specific energy, high current density, low cost, and environmental friendliness. Yet it is not without its drawbacks. The slow oxygen reduction reaction (ORR) of its cathode has become an obstacle to its commercial application. One possible solution is to use platinum (Pt) and Pt-based catalysts, but its high cost and scarce availability make it less ideal. In addition, alkaline KOH (or NaOH) is generally used as the electrolyte, but it leads to the generation of carbonates (CO32-) due to the dissolution of CO2 in the electrolyte as well as the spontaneous corrosion of the anodic zinc in strong alkaline media. This has the effect of slowing down the ionic conductivity of the electrolyte and battery life. Therefore, a neutral electrolyte should be used instead.

Environmentalists are Wrong: Nature Isn’t Sacred and We Should Replace It

Posted by in categories: biotech/medical, ethics, food, information science, life extension, robotics/AI, space, sustainability, transhumanism

Environmentalism and climate change are increasingly being pushed on us everywhere, and I wanted to write the transhumanism and life extension counter argument on why I prefer new technology over nature and sustainability. Here’s my new article:


On a warming planet bearing scars of significant environmental destruction, you’d think one of the 21st Century’s most notable emerging social groups—transhumanists—would be concerned. Many are not. Transhumanists first and foremost want to live indefinitely, and they are outraged at the fact their bodies age and are destined to die. They blame their biological nature, and dream of a day when DNA is replaced with silicon and data.

Their enmity of biology goes further than just their bodies. They see Mother Earth as a hostile space where every living creature—be it a tree, insect, mammal, or virus—is out for itself. Everything is part of the food chain, and subject to natural law: consumption by violent murder in the preponderance of cases. Life is vicious. It makes me think of pet dogs and cats, and how it’s reported they sometimes start eating their owner after they’ve died.

Recycling robot can use sense of touch to sort through the trash

Posted by in categories: robotics/AI, sustainability

MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) is developing a robot that sorts for recycling. Fundamentally, the squad’s robot arm has soft grippers ad the robot can take objects from a conveyor belt and identify what they are made from— by touch.

Tactile sensors on the are the main feature. The sensorized gripper is fully electrical driven. It can detect the difference between paper, metal and plastic.

Global economy would save up to $160 trillion

Posted by in categories: climatology, economics, health, sustainability

In fact, according to IRENA’s new report, the most cost-effective strategy to achieve a “climate-safe future” — keeping global warming below 2 degrees Celsius (3.6 degrees Fahrenheit) — is an accelerated energy transition to renewables and energy efficiency coupled with electrification of key sectors like transportation.

This Renewable Energy Roadmap (REmap) scenario “would also save the global economy up to USD 160 trillion cumulatively over the next 30 years in avoided health costs, energy subsidies and climate damages.”

At the same time, IRENA reports, “every dollar spent on energy transition would pay off up to seven times.”

A Moss Can Naturally Clean Harmful Arsenic From Water

Posted by in categories: biotech/medical, food, sustainability

If you happen to be thirsty in the woods, there are a lot of things you can stick in your canteen to help clean up your drinking water. There are chlorine pills and filters (not crystals — never crystals). And now scientists have identified a certain kind of moss that could do it, too.

The moss is called Warnstorfia fluitans. It grows in Swedish wetlands contaminated with the toxic arsenic from nearby mining operations. Researchers found that the moss brought the arsenic levels of water down to drinkable levels surprisingly quickly, according to research published in the journal Environmental Pollution.

In northern Sweden, iron mines have contaminated much of the water with arsenic, a metal that is also toxic to humans. That harmful combination works its way into agricultural products like rice, traveling throughout the food web.

This moss-covered wall is as air-purifying as 275 urban trees

Posted by in categories: environmental, health, space, sustainability, transportation

From smog-sucking bikes to electric taxis and paint made of car exhaust, designers and architects are stepping up to address air pollution—the world’s single largest health risk. But a new air filter making the rounds in Oslo, Paris, Brussels, and Hong Kong shows that nature may be our best ally in this battle.

Essentially a moss-covered wall, each CityTree removes CO2, nitrogen oxides, and particulate matter from the air while also producing oxygen. A single tree is able to absorb 250 grams of particulate matter a day and remove 240 metric tons of CO2 each year—a level roughly on par with the air purification impact of 275 urban trees. Thirteen feet tall, with a metal frame, the CityTrees are easily installed in a public space, and they even have built-in seating at their base.
