Jays jump in while crows hold out for the treat

Science Daily - 07/12/2023
New research has found that two similar species of birds behave very differently around their favorite food when they have company. Biologists compared the behavior of two species of corvids, Eurasian jays and New Caledonian crows, both capable of displaying self-control through delayed gratification. The researchers found that jays will settle for an immediate, less preferred food option when another bird is present, while crows will always hold out for their favorite food, regardless of the social context.

Fascicle gearing dynamics: Unveiling 3D rotation effects in muscle elongation

Science Daily - 06/12/2023
Muscle belly elongation due to passive lengthening is frequently presumed to be equivalent to that of fascicles. However, researchers have now revealed that since the muscle fascicle arrangement is three-dimensional, passive lengthening can lead to fascicle rotation in both the coronal and sagittal planes. This 'gearing effect' helps prevent the fibers from overstretching and enhances overall flexibility.

Greenhouse gases in oceans are altered by climate change impact on microbes

Science Daily - 06/12/2023
The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.

Repeated blast exposures may harm the brain health of military personnel

Grinding coffee with a splash of water reduces static electricity and makes more consistent and intense espresso

Science Daily - 06/12/2023
The fracturing and friction of coffee beans during grinding generates electricity that causes coffee particles to clump together and stick to the grinder. Researchers report that coffee beans with higher internal moisture produce less static electricity, which means less coffee is wasted and there is less mess to clean up. This effect can be simulated by adding a small amount of water to beans immediately before grinding them. The team also showed that grinding with a splash of water produces more consistent and intense espresso.

The ocean may be storing more carbon than estimated in earlier studies

Science Daily - 06/12/2023
The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report. Scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed. Plankton gobble up carbon dioxide and, as they grow, convert it into organic tissue via photosynthesis. When they die, part of the plankton is transformed into particles known as 'marine snow'.  Being denser than seawater, these particles sink down to the seabed thus storing carbon there and providing essential nutrients for a wide range of deep-sea organisms, from tiny bacteria to deep-sea fish. By analysing a bank of data collected from around the world by oceanographic vessels since the 1970s, the team of seven scientists were able to digitally map fluxes of organic matter throughout the world's oceans. The resulting new estimate of carbon storage capacity is 15 gigatonnes per year, an increase of around 20% compared with previous studies (11 gigatonnes per year) published by the IPCC in its 2021 report. This reassessment of the ocean's storage capacity represents a significant advance in our understanding of carbon exchanges between the atmosphere and the ocean at the global level. While the team stresses that this absorption process takes place over tens of thousands of years, and is therefore not sufficient to offset the exponential increase in CO2 emissions caused by worldwide industrial activity since 1750, the study nonetheless highlights the importance of the ocean ecosystem as a major player in the long-term regulation of the global climate.
