Hydrogen-based fuels should primarily be used in sectors such as aviation or industrial processes that cannot be electrified, finds a team of researchers. Producing these fuels is too inefficient, costly and their availability too uncertain, to broadly replace fossil fuels for instance in cars or heating houses. For most sectors, directly using electricity for instance in battery electric cars or heat pumps makes more economic sense.
Researchers: Unlike humans, who map the world in units of distance, bats map the world in units of time. What this means is that the bat perceives an insect as being at a distance of nine milliseconds, and not one and a half meters, as was previously thought.
A new study found overlooked tsunami hazards related to undersea, near-shore strike-slip faults, especially for coastal cities adjacent to faults that traverse inland bays. Several areas around the world may fall into this category, including the San Francisco Bay area, Izmit Bay in Turkey and the Gulf of Al-Aqaba in Egypt.
The researchers performed imaging at the resolution of a single cell and discovered that the drilling movement occurs in specific cells at the tip of the root, and apparently enables the root to penetrate the ground.
Cooling our streets, reducing air pollution and improving our wellbeing, nature can provide a host of solutions to the issues facing our cities, according to a new report by the British Ecological Society.
A new study has shown that the key to filming the largest deep-sea squid on this planet was our knowledge of this animal's unique eye.
In the medium and long-term periods, climate shocks favoured cooperation among diverse groups of people. Indeed, by enlarging access to political and property rights, elites who had decision-making powers could work with other groups who held the skills and tools to overcome those crises
Analysis of sales data and flood risk data over two decades indicates that housing markets fail to fully account for information about flood risk. The findings suggest that policies to improve risk communication could influence market outcomes. (WATCH VIDEO: https://www.youtube.com/watch?v=n18s5kcE0So)
The number of solar panels within shortest distance from a house is the most important factor in determining the likelihood of that house having a solar panel, when compared with a host of socio-economic and demographic variables. This is shown in a new study by scientists using satellite and census data of the city of Fresno in the US, and employing machine learning.
Diversity in diet plays a role in the complexity of venom in pit vipers such as rattlesnakes, copperheads and cottonmouths. But new collaborative research by Clemson University scientists found the number of prey species a snake ate did not drive venom complexity. Rather, it was how far apart the prey species were from each other evolutionarily.
