Even treated wood prevents bacterial transmission by hand      (via sciencedaily.com)     Original source 

According to a new study, surface treatment and moisture affect the antibacterial properties of wood. Based on the findings, treated wood should be increasingly used as surface material.

Mystery of volcanic tsunami solved after 373 years      (via sciencedaily.com)     Original source 

The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers has now surveyed Kolumbo's underwater crater with modern imaging technology and reconstructed the historical events. They found that the eyewitness accounts of the natural disaster can only be described by a combination of a landslide followed by an explosive eruption.

Venus had Earth-like plate tectonics billions of years ago, study suggests      (via sciencedaily.com)     Original source 

Venus, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of early life on Venus, its evolutionary past and the history of the solar system.

Superdeep diamonds provide a window on supercontinent growth      (via sciencedaily.com)     Original source 

Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research. These findings demonstrate that superdeep diamonds can provide a window through space and time into the supercontinent growth and formation process.

Researchers probe molten rock to crack Earth's deepest secrets      (via sciencedaily.com)     Original source 

An international team re-created molten rock conditions deep within the Earth and measured the spin states of iron atoms within that rock melt. An iron atom's spin state drives its magnetic behavior and reactivity in chemical reactions, and can influence whether iron prefers to be in the molten or solid rock.

Soil carried on sea freight loaded with dangerous pests and diseases, research finds      (via sciencedaily.com)     Original source 

While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.

Heat waves harm bird reproduction on agricultural lands      (via sciencedaily.com)     Original source 

The effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. A new study found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes.

California supervolcano is cooling off but may still cause quakes      (via sciencedaily.com)     Original source 

New high-resolution images of the Long Valley Caldera indicate that the subsurface environment is cooling off, releasing gas and fluids that contribute to seismic activity.

Yeast speeds discovery of medicinal compounds in plants      (via sciencedaily.com)     Original source 

Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.

Ancient diamonds shine light on the evolution of Earth      (via sciencedaily.com)     Original source 

Formed millions to billions of years ago, diamonds can shine light into the darkest and oldest parts of the Earth's mantle. The analysis of ancient, superdeep diamonds dug up from mines in Brazil and Western Africa, has exposed new processes of how continents evolved and moved during the early evolution of complex life on Earth. These diamonds that were formed between 650 and 450 million years ago on the base of the supercontinent Gondwana, were analysed by an international team of experts, and have shown how supercontinents such as Gondwana were formed, stabilised, and how they move around the planet.

Orchid without bumblebee on island finds wasp, loses self      (via sciencedaily.com)     Original source 

Because the bumblebee that an orchid relies on for pollination does not exist on a remote island, the plant gets pollinated by an island wasp. Researchers found that this came at the cost of being hybridized with another orchid species adapted to being pollinated by the wasp. The finding showcases how plants in ecological relationships adapt to changing circumstances.

Study reveals our European ancestors ate seaweed and freshwater plants      (via sciencedaily.com)     Original source 

Researchers say they have found 'definitive' archaeological evidence that seaweeds and other local freshwater plants were eaten in the mesolithic, through the Neolithic transition to farming and into the Early Middle Ages, suggesting that these resources, now rarely eaten in Europe, only became marginal much more recently.

Endemic malaria found in high, dry northwestern Kenya      (via sciencedaily.com)     Original source 

Turkana County in northwestern Kenya was thought to be too dry for the mosquitoes that harbor malaria-causing parasites. But that assumption may have been wrong, according to a new study by malaria researchers. The arrival of a new mosquito and a more pernicious species of parasite could reverse the progress East Africa has made in controlling malaria.

Bouldering in south-central Madagascar: A new 'rock-climbing' gecko species of the genus Paroedura      (via sciencedaily.com)     Original source 

A new Paroedura gecko species was reported at two small forest sites, Anja Reserve and Tsaranoro Valley forest, in the south-central plateau of Madagascar. Thanks to the recently collected samples, it was described and named after its preferred habitat, the boulders surrounded by the last remaining forests at these sites. Its conservation status was evaluated as Critically Endangered given its tiny distributional range.
