Is the p-value pointless?
Phys.org - latest science and technology news stories - Hace 1 hora
For the first time in its 177-year history, the American Statistical Association (ASA) has voiced its opinion and made specific recommendations for a statistical practice. The subject of their ire? The (arguably) most common statistical output, the p-value. The p-value has long been the primary metric for demonstrating that study results are "statistically significant," usually by achieving the semi-arbitrary value of p ce of the p-value has been greatly overstated and the scientific community has become over-reliant on this one – flawed – measure.

Wind energy is a growing alternative to reduce greenhouse gas emissions from the combustion of fossil fuels. However, one impact of large-scale wind energy development has been widespread mortality of bats. A new study from the University of Maryland Center for Environmental Science tracks down the origin of bats killed by wind turbines in the Appalachian region in hopes of better understanding the risks to affected populations.

The behavior of a few rubidium atoms in a cloud of 40,000 hardly seems important. But a handful of the tiny particles with the wrong energy may cause a cascade of effects that could impact future quantum computers.
Semiconductor-inspired superconducting quantum computing devices
Phys.org - latest science and technology news stories - Hace 1 hora
Builders of future superconducting quantum computers could learn a thing or two from semiconductors, according to a report in Nature Communications this week. By leveraging the good ideas of the natural world and the semiconductor community, researchers may be able to greatly simplify the operation of quantum devices built from superconductors. They call this a "semiconductor-inspired" approach and suggest that it can provide a useful guide to improving superconducting quantum circuits.

Evolution meets biochemistry to better understand how dopamine receptors work
Phys.org - latest science and technology news stories - Hace 1 hora
Proteins are molecular machines that carry out most of the work performed by the cells in the body, but when proteins fail at doing their job disease usually follows. To perform their functions, proteins need to maintain a particular structure and specific motions, and how proteins achieve that is still not completely understood. In an article published in the Proceedings of the National Academy of Sciences, Baylor College of Medicine researchers have contributed a new piece to the puzzle that helps explain how proteins maintain their structure and function, and opens the possibility... más »

The ocean's Twilight Zone can feed the world, but at what cost ?
Phys.org - latest science and technology news stories - Hace 1 hora
Life in the Twilight Zone constitutes a huge potential source of fishmeal and omega 3 fatty acids that could feed the world's population. However, it exists in an unregulated space where there are no rules for fishing. And there exists a lack of understanding of the biological processes in the Twilight Zone making it impossible to accurately estimate the fishing pressure the stocks can sustain.
Can improved agricultural practices help combat climate change?
Phys.org - latest science and technology news stories - Hace 1 hora
Did you know that over half of global non-carbon dioxide (non-CO2) greenhouse gas (GHG) emissions are accountable to agriculture? According to new a research study recently published in the Journal of Integrative Environmental Sciences, this figure is set to rise substantially in the next two decades, especially in developing countries. However, by analysing US Environmental Protection Agency (USEPA) data and models, the authors have projected that there is significant potential for the agricultural sector to provide relatively low-cost opportunities for reducing GHG emissions by 2030.

Biogas is an important energy source that plays a central role in the energy revolution. Unlike wind or solar energy, biogas can be produced around the clock. Could it soon perhaps even be produced to meet demand? A team of international scientists, including microbiologists from the Helmholtz Centre for Environmental Research (UFZ), scientists from Aarhus University and process engineers from the Deutsches Biomasseforschungszentrum (DBFZ), have been studying the feasibility of this kind of flexible biogas production. Among their findings, for example, is the discovery that biogas p... más »

Variability of major oceanic currents driven by climate change
Phys.org - latest science and technology news stories - Hace 1 hora
(Phys.org)—The Earth's oceanic system isn't just the big, blue puddle of water that globes suggest; its waters are stirred by a vast system called thermohaline circulation, a process driven by varying water densities, heat, and the interactions of freshwater and salt water. Thermohaline circulation moves energy and matter around the globe and drives the planet's climate, but it also responds to changing climate conditions.

For a long time, it was thought that the sole role of the immune system was to distinguish between friend and foe and to fend off pathogens. In fact, it is more like a microbial management system that is also involved in accommodating beneficial microorganisms in the plant when required.

New tech captures over 90% of carbon dioxide from exhaust gases for use in industry
Phys.org - latest science and technology news stories - Hace 1 hora
Carbon dioxide can be a valuable resource for industry. It can, for example, be used as a fertilizer in greenhouses to improve plant growth. But for reasons of climate protection, it would be problematic to produce CO2 for this purpose, using fossil fuels. Filtering CO2 out of the exhaust gases from industrial processes and turning it into something useful would be much more environmentally friendly.

Heterostructures (referred to as Van der Waals {VdW}) are attracting a great deal of attention due to their diverse physical and chemical properties. A VdW heterostructure is assembled by stacking two or more different 2D semiconducting crystals on top of each other. The structure is grown by repeating the practice, the resulting stack represents an artificial material constructed in a certain sequence, akin to Lego blocks.
