Flaws in industry-funded pesticide evaluation

Posted by in categories: food, health, neuroscience

The company-funded animal test was performed to ascertain how neural development is affected by the pesticide chlorpyrifos, which is used on a wide variety of crops around the world, including some 20 EU countries. The test laboratory concluded that there was no such effect, even at high doses.


Academic researchers have examined raw data from a company-funded safety evaluation of the pesticide chlorpyrifos. They discovered an effect on the brain architecture of the exposed laboratory animals at all tested doses, which was not included in the reported conclusions. Karolinska Institutet in Sweden led this independent study, which is published in the scientific journal Environmental Health.

All pesticides must be evaluated in terms of their safety and potential risks for human health before they can officially be approved. Normally the companies that manufacture the products cover the cost of such evaluations and commission test laboratories to perform the necessary animal tests.

More realistic research needed on substances that enter the environment

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

Chemical substances and nanomaterials are processed on a massive scale in diverse products, while their risks have not been properly assessed. Time and again synthesised substances have been shown to pollute the environment more than lab tests predicted. This is the warning given by Professor of Ecotoxicology Martina Vijver from Leiden University in her inaugural lecture on 16 November.

Laboratory tests are inadequate, according to Vijver, because they do not imitate a complete ecosystem. In her inaugural lecture she will discuss in greater detail two examples of substances where more realistic research is needed: agricultural toxins and nanoparticles. ‘But the same can be said for many other groups of substances, such as antibiotics, plasticizers and GenX.’

USB form neural compute stick makes debut at developer event

Posted by in category: robotics/AI

Intel has unveiled the Intel Neural Compute Stick 2. It looks like a standard USB thumb drive, and it runs on a USB 3.0 port, but is oh-more-special. CNET said the new AI “brain” sticks into the side of your PC.

Andrew Tarantola in Engadget summed up its significance. “Intel’s NCS2 is essentially a self-contained neural network on a thumbdrive and should make developing those sorts of devices faster and easier by offloading much of the processing power required to train them to its onboard Movidius Myriad X vision processing unit (VPU).”

The debut took place Wednesday, Nov. 14, at the Intel AI Devcon in Beijing.

Organisms found on hike in the woods are like no other life on Earth News

Posted by in category: genetics

Canadian researchers have discovered a new kind of organism that’s so different from other living things that it doesn’t fit into the plant kingdom, the animal kingdom, or any other kingdom used to classify known organisms.

Two species of the microscopic organisms, called hemimastigotes, were found in dirt collected on a whim during a hike in Nova Scotia by Dalhousie University graduate student Yana Eglit.

A genetic analysis shows they’re more different from other organisms than animals and fungi (which are in different kingdoms) are from each other, representing a completely new part of the tree of life, Eglit and her colleagues report this week in the journal Nature.

FCC tells SpaceX it can deploy up to 11,943 broadband satellites

Posted by in category: satellites

SpaceX today received US approval to deploy 7,518 broadband satellites, in addition to the 4,425 satellites that were approved eight months ago.

The Federal Communications Commission voted to let SpaceX launch 4,425 low-Earth orbit satellites in March of this year. SpaceX separately sought approval for 7,518 satellites operating even closer to the ground, saying that these will boost capacity and reduce latency in heavily populated areas. That amounts to 11,943 satellites in total for SpaceX’s Starlink broadband service.

SpaceX “proposes to add a very-low Earth orbit (VLEO) NGSO [non-geostationary satellite orbit] constellation, consisting of 7,518 satellites operating at altitudes from 335km to 346km,” the FCC said in the draft of the order that it approved unanimously today. The newly approved satellites would use frequencies between 37.5 and 42GHz for space-to-Earth transmissions and frequencies between 47.2 and 51.4GHz for Earth-to-space transmissions, the FCC said.

Albert Einstein, Holograms and Quantum Gravity

Posted by in categories: holograms, particle physics, quantum physics

In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.

Elon Musk’s Boring Company is launching DIY watchtowers with bricks from tunnel dirt

Posted by in category: Elon Musk

Getting rid of dirt is one of the largest costs of digging tunnels and Elon Musk’s Boring Company is exploring some creative ways to do that.

They are launching “DIY watchtowers” with bricks made of dirt from their tunnels.

They estimate that the cost of moving the dirt can represent up to 15% of the total cost of a tunnel, which is why they want to turn the dirt into a product itself.

Nio deploys 18 battery swap stations covering 2,000+ km expressway

Posted by in category: sustainability

No one in the electric vehicle space has managed to make battery swapping work yet, but Nio is trying big time with 18 new battery swap stations covering a 2,000+ km expressway in China.

Several companies tried and failed at battery swapping. Tesla had a battery swap system that they seemingly abandoned and Better Place went bankrupt.

But you could say Tesla didn’t try that hard and has instead bet on fast-charging and Better Place was a little too ahead of its time.
