Scientists discover a new species of snake hiding in plain sight

Sometimes, looking at things we thought we knew with fresh eyes (and new tools) can lead to incredible discoveries.

That’s what happened when Jeff Weinell, a graduate research assistant at the University of Kansas’ Biodiversity Institute, found out that three specimens of snakes preserved in the institute’s biodiversity collection, found in field missions between 2006 and 2012 and overlooked up to this point, belonged in a category of their own.

The three snake specimens are the only known members of a new snake genus, called Levitonius, and a new snake species, called Levitonius mirus.

Planetary Protection Policy: For sustainable space exploration and to safeguard our biosphere

COSPAR’s Planetary Protection Policy ensures scientific investigations related to the origin and distribution of life are not compromised.

Protecting the Earth from alien life sounds like the latest plot for a blockbuster thriller set in outer space. Whether it’s an invasion or a mysterious alien illness, the extraterrestrial threat to our planet has been well-explored in science fiction. But protecting the Earth from extraterrestrial contamination is not just a concept for our entertainment; as we explore further across our solar system and begin to land on our neighbouring planetary bodies, ensuring that we don’t bring potentially dangerous material home to Earth or indeed carry anything from Earth that may contaminate another planet is a responsibility we must take seriously.

So, who is responsible for ensuring that our space exploration is completed safely? Many nations around the world have their own space agencies, such as NASA and the European Space Agency, who run many different types of missions to explore space. States are responsible for their space activities under the Outer Space Treaty of 1967, including governmental and non-governmental actors. The Outer Space Treaty, among several provisions, regulates in its Article IX against harmful contamination. One of the core activities of the Committee on Space Research (COSPAR) is to develop, maintain, and promote a Policy on Planetary Protection, as the only international reference standard for spacefaring nations and in guiding compliance with Article IX of the Outer Space Treaty.

As we explore further across our solar system, ensuring we don’t bring potentially dangerous material home or indeed carry anything from Earth that may contaminate another planet and compromise scientific investigations is a responsibility we must take seriously.

COSPAR and its role COSPAR is part of the International Science Council, a non-governmental organisation that brings together many different scientific unions and research councils from all over the world. COSPAR was formed to promote international scientific research in space and provide a forum for the discussion of challenges to scientific exploration. COSPAR has a panel that regularly reviews the most up-to-date scientific research and advises COSPAR on new adaptations to planetary protection, for which policy updates and implementation guidelines are required.

Solar panels made from food waste win inaugural James Dyson Sustainability Award

Engineering student Carvey Ehren Maigue has been named the James Dyson Awards first-ever global sustainability winner for his AuReus system, in which waste crops are turned into cladding that can generate clean energy from ultraviolet light.

Unlike traditional solar panels, which only work in clear conditions and must face the sun directly because they rely on visible light, the translucent AuReus material is able to harvest power from invisible UV rays that pass through clouds.

As a result, it is able to produce energy close to 50 per cent of the time according to preliminary testing, compared to 15 to 22 per cent in standard solar panels.

Scientists Find Remarkable New Snake Species in Philippines

The Waray dwarf burrowing snake lives a fossorial lifestyle and likely has a diet that is specialized on earthworms or other limbless invertebrates.

It has a maximum total length of 17.2 cm (6.8 inches), making it the smallest known species in the snake superfamily Elapoidea.

“The Waray dwarf burrowing snake has among the fewest number of vertebrae of any snake species in the world, which is likely the result of miniaturization and an adaptation for spending most of its life underground,” said Jeff Weinell, a doctoral candidate in the Department of Ecology and Evolutionary Biology and the Biodiversity Institute at the University of Kansas.

Making jet fuel out of carbon dioxide

A team of researchers affiliated with several institutions in the U.K. and one in Saudi Arabia has developed a way to produce jet fuel using carbon dioxide as a main ingredient. In their paper published in the journal Nature Communications, the group describes their process and its efficiency.

As scientists continue to look for ways to reduce the amount of emitted into the atmosphere, they have increasingly focused on certain business sectors. One of those sectors is the , which accounts for approximately 12% of transportation-related carbon dioxide emissions. Curbing in the aviation industry has proved to be challenging due to the difficulty of fitting heavy batteries inside of aircraft. In this new effort, the researchers have developed a that can be used to produce carbon-neutral jet fuel.

The researchers used a process called the organic combustion method to convert carbon dioxide in the air into jet fuel and other products. It involved using an iron catalyst (with added potassium and manganese) along with hydrogen, citric acid and carbon dioxide heated to 350 degrees C. The process forced the apart from the oxygen atoms in CO2 molecules, which then bonded with hydrogen atoms, producing the kind of hydrocarbon molecules that comprise liquid jet fuel. The process also resulted in the creation of water molecules and other products.

Goldilocks and the three quantum dots: Just right for peak solar panel performance

Scientists in Australia have developed a process for calculating the perfect size and density of quantum dots needed to achieve record efficiency in solar panels.

Quantum dots, man-made nanocrystals 100, 000 times thinner than a sheet of paper, can be used as sensitisers, absorbing infrared and and transferring it to other molecules.

This could enable new types of to capture more of the light spectrum and generate more electrical current, through a process of ‘light fusion’ known as photochemical upconversion.

Remarkable New Species of Snake Found Hidden in a Biodiversity Collection – Occupies Its Own Branch on Snake Tree of Life

Waray Dwarf Burrowing Snake occupies its own branch on snake tree of life.

To be fair, the newly described Waray Dwarf Burrowing Snake (Levitonius mirus) is pretty great at hiding.

In its native habitat, Samar and Leyte islands in the Philippines, the snake spends most of its time burrowing underground, usually surfacing only after heavy rains in much the same way earthworms tend to wash up on suburban sidewalks after a downpour.
