New species formed when the Mediterranean dried up

Eurekalert - May 18 2021 - 00:05
A new study may have uncovered why wall lizards have become the most successful reptile in the Mediterranean region. The results reveal how drastic changes in sea levels and climate 6 million years ago affected species formation in the area. The researchers believe they can now explain why the lizards became so diverse and widespread, something that has puzzled biologists since the 19th century. The study is published in Nature Communications.

Grazing management of salt marshes contributes to coastal defense

Eurekalert - May 18 2021 - 00:05
Combining natural salt marsh habitats with conventional dikes may provide a more sustainable alternative for fully engineered flood protection. Researchers of the University of Groningen and the Royal Netherlands Institute for Sea Research studied how salt marsh management can be optimized for coastal defence purposes. They found that grazing by both cattle and small herbivores such as geese and hare and artificial mowing can reduce salt marsh erosion, therefore contributing to nature-based coastal defence.

Electric cars: Special dyes could prevent unnecessary motor replacements

Eurekalert - May 18 2021 - 00:05
In the near future dyes in electric motors might indicate when cable insulation is becoming brittle and the motor needs replacing. Scientists at Martin Luther University Halle-Wittenberg (MLU), together with ELANTAS, a division of the specialty chemicals group ALTANA, have developed a new process that enables the dyes to be directly integrated into the insulation. By changing colour, they reveal how much the insulating resin layer around the copper wires in the motor has degraded.

'Bite' defects revealed in bottom-up graphene nanoribbons

Eurekalert - May 18 2021 - 00:05
Collaboration between two NCCR MARVEL labs has identified a new type of defect as the most common source of disorder in on-surface synthesized graphene nanoribbons (GNRs). The researchers identified the atomic structure of these "bite" defects and investigated their effect on quantum electronic transport in two different types of GNR. They also established guidelines for minimizing the detrimental impact of these defects and proposed defective zigzag-edged nanoribbons as suitable platforms for certain applications in spintronics.

LHAASO discovers a dozen PeVatrons and photons exceeding 1 PeV and launches ultra-high-energy gamma

Eurekalert - May 18 2021 - 00:05
China's Large High Altitude Air Shower Observatory (LHAASO)--one of the country's key national science and technology infrastructure facilities--has found a dozen ultra-high-energy (UHE) cosmic accelerators within the Milky Way. It has also detected photons with energies exceeding 1 peta-electron-volt (quadrillion electron-volts or PeV), including one at 1.4 PeV. The latter is the highest energy photon ever observed.

Megaprojects threaten water justice for local communities

Eurekalert - May 18 2021 - 00:05
Urban megaprojects tend to be the antithesis of good urban planning. They have a negative impact on local water systems, deprive local communities of water-related human rights, and their funders and sponsors have little accountability for their impact.

Colonization of the Antilles by South American fauna: Giant sunken islands as a passageway

Eurekalert - May 18 2021 - 00:05
Fossils of land animals from South America have been found in the Antilles, but how did these animals get there? According to scientists from the CNRS, l'Université des Antilles, l'Université de Montpellier and d'Université Côte d'Azur, land emerged in this region and then disappeared beneath the waves for millions of years, explaining how some species were able to migrate to the Antilles. This study will be published in June 2021 issue in Earth-Science Reviews.

City of Hope and Griffith University develop direct-acting antiviral to treat COVID-19

Eurekalert - May 18 2021 - 00:05
An international team of scientists have developed an experimental direct-acting antiviral therapy to treat COVID-19. Traditional antivirals reduce symptoms and help people recover earlier. This next-generation antiviral approach used gene-silencing RNA technology called siRNA (small-interfering RNA) to attack the virus' genome directly, which stops the virus from replicating, as well as lipid nanoparticles designed at Griffith University and City of Hope to deliver the siRNA to the lungs, the critical site of infection.
