The crow's best friend: Humans      (via sciencedaily.com)     Original source 

A new study has found that when humans are suddenly absent from the urban environment, the activity of the crows and ringneck parakeets that 'live' in the area reduces significantly. Conversely, the graceful prinias, who are generally considered shy, increased their activity.

Network of quantum sensors boosts precision      (via sciencedaily.com)     Original source 

Quantum sensor technology promises even more precise measurements of physical quantities. A team has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.

A model for the evolution of intelligence      (via sciencedaily.com)     Original source 

When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence. In the largest experimental study ever conducted on this topic, researchers have shown that foraging problems requiring overcoming obstacles, such as removing the lid off a container of food, are the only predictors of brain size and innovative behavior in the wild.

Study results show 25% of pregnant people are not getting enough omega-3 fatty acids from their diet or dietary supplements      (via sciencedaily.com)     Original source 

Results from a new US nationwide cohort study show that, despite strong recommendations in favor of consuming omega-3 fatty acids for optimal pregnancy outcomes and offspring health, 25% of participants reported rarely, or never eating fish during pregnancy, with fewer taking omega-3 supplements.

Umbrella for atoms: The first protective layer for 2D quantum materials      (via sciencedaily.com)     Original source 

As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.

When the music changes, so does the dance: Controlling cooperative electronic states in Kagome metals      (via sciencedaily.com)     Original source 

Playing a different sound track is, physically speaking, only a minute change of the vibration spectrum, yet its impact on a dance floor is dramatic. People long for this tiny trigger, and as a salsa changes to a tango completely different collective patterns emerge. For such a tiny stimulus to have an effect, the crowd needs to know more than just one dance. Electrons in metals tend to show only one behavior at zero temperature, when all kinetic energy is quenched.

Slimming down a colossal fossil whale      (via sciencedaily.com)     Original source 

A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.

Small dietary changes can cut your carbon footprint by 25%      (via sciencedaily.com)     Original source 

New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.

Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature      (via sciencedaily.com)     Original source 

More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022. The GBF focuses on understanding why biodiversity is declining and what actions are needed to reverse this trend. However, according to researchers, implementing the plan is challenging because information about biodiversity changes is not evenly available everywhere, and is uncertain in many places.

The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus      (via sciencedaily.com)     Original source 

Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.

The veil varies more than the threat: Predator selection on variability in camouflage and warning signals      (via sciencedaily.com)     Original source 

Researchers leveraged open-access digital collections to validate an age-old hypothesis in evolutionary ecology. The classic hypothesis proposes that predators select for a great variety of camouflage and a limited variety of warning signals, but the idea has never been tested on natural prey.

Climate change shrinking fish      (via sciencedaily.com)     Original source 

Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other species for food. During the 2010s, while the number of Japanese sardine and chub mackerel moderately increased, the effect of climate change warming the ocean appears to have resulted in more competition for food, as cooler, nutrient-dense water could not easily rise to the surface. These results have implications for fisheries and policymakers trying to manage ocean resources under future climate change scenarios.

Quantum films on plastic      (via sciencedaily.com)     Original source 

Researchers have discovered that thin films of elemental bismuth exhibit the so-called non-linear Hall effect, which could be applied in technologies for the controlled use of terahertz high-frequency signals on electronic chips. Bismuth combines several advantageous properties not found in other systems to date, as the team reports. Particularly: the quantum effect is observed at room temperature. The thin-layer films can be applied even on plastic substrates and could therefore be suitable for modern high-frequency technology applications.
