Audacious French company Nawa showed off a concept bike in 2019, claiming its supercapacitor-hybrid battery pack could massively boost power and urban range for electric motorcycles. Now, it seems we’ll get a chance to see if the numbers stack up.
We’ve been following Nawa since 2018, when we first spoke to these guys about the potential benefits of using powerful ultracapacitors alongside energy-dense lithium batteries to extend the range and boost the peak power of electric vehicles.
The company wrapped the idea up into a futuristic-looking concept bike for CES 2020, and put some outrageous figures to its claims. Using a 9-kWh lithium battery, you would expect to get around 180 km (110 miles) of urban riding out of a full charge. The Nawa Racer proposed that adding a 0.1-kWh ultracapacitor to the system would boost that range up to around 300 km (180 miles), while unlocking some serious acceleration power to boot.
Plastic pollution has become one of the most pressing environmental issues now that the rapidly increased production of disposable plastic products is far beyond the world’s capacity for recycling and upcycling waste plastics. Although recent studies have provided a few catalytic strategies for producing value-added fuel and chemical products from polyethylene (PE) waste, the kinetic rates and/or selectivities are unsatisfactory, even with extended processing time (24 h) and high temperatures (280°C). This work reports a liquid-phase catalytic hydrogenolysis process that highly efficiently converts high-density PE to jet-fuel-and lubricant-range hydrocarbons under relatively mild conditions. The application of this efficient liquid-phase catalytic hydrogenolysis process could provide a promising approach for selectively producing high-value products, such as lubricants, from waste PE and other polyolefin polymers.
Dr. Thomas Lovejoy, is an innovative conservation biologist, who is Founder and President of the non-profit Amazon Biodiversity Center, the renowned Biological Dynamics of Forest Fragments Project, and the person who coined the term “biological diversity”.
Dr. Lovejoy currently serves as Professor in the department of Environmental Science and Policy at George Mason University, and as a senior fellow at the United Nations Foundation based in Washington, DC.
Dr. Lovejoy has also served as the World Bank’s chief biodiversity advisor and the lead specialist for environment for Latin America and the Caribbean, the first Biodiversity Chair of the H. John Heinz III Center for Science, Economics and the Environment, President of the Heinz Center, and chair of the Scientific Technical Advisory Panel (STAP) for the Global Environment Facility (GEF), the multibillion-dollar funding mechanism for developing countries in support of their obligations under international environmental conventions.
Spanning the political spectrum, Dr. Lovejoy has served on science and environmental councils under the Reagan, Bush, and Clinton administrations. At the core of these many influential positions are seminal ideas, which have formed and strengthened the field of conservation biology.
In the 1980s, Dr. Lovejoy brought international attention to the world’s tropical rainforests, and in particular, the Brazilian Amazon, where he has worked since 1965.
With multiple co-edited books (including Biodiversity and Climate Change: Transforming the Biosphere; Drones for Conservation — Field Guide for Photographers, Researchers, Conservationists and Archaeologists; Costa Rican Ecosystems; Climate Change and Biodiversity; On the Edge: The State and Fate of the World’s Tropical Rainforests), Dr. Lovejoy is credited as a founder of the field of climate change biology. He also founded the series Nature, the popular long-term series on public television.

Here’s what we already know about Ford’s electric F-150.
Ford is set to unveil its next major electric vehicle, the F-150 Lightning, at 9:30PM ET on Wednesday, May 19th. But this isn’t just another EV event. An electric version of the automaker’s iconic F-series pickup truck is a very big deal for Ford, for the auto world, for car buyers, and even for the US economy.
Ford is very proud of its F-series trucks, and for good reason. It’s the bestselling truck in the US for 44 years. It’s also the bestselling vehicle in the country, period. According to Edmunds, F-series trucks are the most popular vehicle in 30 out of 50 states in the US.
That means the F-Series trucks is central to Ford’s profitability. The Detroit automaker raked in around $42 billion in revenue in 2019 from nearly 900000 F-series truck sales in the US, according to a Boston Consulting Group study commissioned by Ford — more than most major companies and about four times as much as Tesla made in all of 2020.
Imagine filling up your gas tank with 10 gallons of gas, driving just far enough to burn a half gallon and discarding the rest. Then, repeat. That is essentially the practice that the U.S. nuclear industry is following.
Spent nuclear fuel from power plants still has 95% of its potential to produce electricity. Current plans are to dispose of the spent nuclear fuel in a geologic repository. So, why is it not recycled? It turns out that separating usable versus unusable parts of spent nuclear fuel is complicated.
“Spent nuclear fuel contains roughly half of the periodic table. So, from a chemistry standpoint, there’s a lot going on,” said Gregg Lumetta, PNNL chemist and laboratory fellow. “And to reduce proliferation risk, it is best if pure plutonium is not produced at any point in the separation process.”
Why luxury brands like Hermès, Iris Van Herpen, and Stella McCartney are turning to mushrooms for an eco-alternative to leather.
The wondrous fungi-inspired creations in Dutch couture designer Iris Van Herpen’s Spring 2021 collection are like nothing else in the fashion world. Undulating crowns of brass coils top delicate micro-plissé gowns with bodices formed from sinuous silk tendrils. An early adopter of 3D printing and advocate for sustainability, van Herpen has emerged as a kind of oracle within the fashion industry. She spent lockdown in Amsterdam reading biologist Merlin Sheldrake’s book, Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures, which describes the hidden world of mycelium, the sprawling underground root-like networks of fungi (the visible part we know as mushrooms are akin to fruit on trees).
