Migrating starlings are no copycats      (via sciencedaily.com)     Original source 

Young, na ve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other. By revisiting a classic 'displacement' experiment and by adding new data, a team of researchers have settled a long-lasting debate.

Cool roofs are best at beating cities' heat      (via sciencedaily.com)     Original source 

Painting roofs white or covering them with a reflective coating would be more effective at cooling cities like London than vegetation-covered 'green roofs,' street-level vegetation or solar panels, finds a new study led by UCL researchers.

Blue and great tits deploy surprisingly powerful memories to find food      (via sciencedaily.com)     Original source 

Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.

Giant clams may hold the answers to making solar energy more efficient      (via sciencedaily.com)     Original source 

Solar panel and biorefinery designers could learn a thing or two from iridescent giant clams living near tropical coral reefs, according to a new study. This is because giant clams have precise geometries -- dynamic, vertical columns of photosynthetic receptors covered by a thin, light-scattering layer -- that may just make them the most efficient solar energy systems on Earth.

Moving beyond the 80-year-old solar cell equation      (via sciencedaily.com)     Original source 

Physicists have made a significant breakthrough in solar cell technology by developing a new analytical model that improves the understanding and efficiency of thin-film photovoltaic (PV) devices.

Genetic patterns of world's farmed, domesticated foxes revealed via historical deep-dive      (via sciencedaily.com)     Original source 

Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery.

New model could help provide expectant mothers a clearer path to safe fish consumption      (via sciencedaily.com)     Original source 

Research creates a framework to better balance the nutritional benefit of fish consumption with the risk of mercury exposure to the developing brain.

New mathematical model sheds light on the absence of breastfeeding in male mammals      (via sciencedaily.com)     Original source 

Mathematicians ave put forward a hypothesis which suggests that the reason male mammals don't breastfeed might be driven by the rich community of microbes that lives in breast milk and which plays an important part in establishing the gut microbiome of the infant.

Pacific cod can't rely on coastal safe havens for protection during marine heat waves      (via sciencedaily.com)     Original source 

During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new study found.

Bird flu stays stable on milking equipment for at least one hour      (via sciencedaily.com)     Original source 

H5N1 virus in unpasteurized milk is stable on metal and rubber components of commercial milking equipment for at least one hour, increasing its potential to infect people and other animals.

Invasive ants spread by hitchhiking on everyday vehicles      (via sciencedaily.com)     Original source 

Ants might spread to new locations by stowing away on everyday vehicles. Previously, this was thought to occur mostly on agricultural equipment.

Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds      (via sciencedaily.com)     Original source 

We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.

Brain's 'escape switch' controlled by threat sensitivity dial      (via sciencedaily.com)     Original source 

Neuroscientists have discovered how the brain bidirectionally controls sensitivity to threats to initiate and complete escape behaviour in mice. These findings could help unlock new directions for discovering therapies for anxiety and post-traumatic stress disorder (PTSD).

New tomato, potato family tree shows that fruit color and size evolved together      (via sciencedaily.com)     Original source 

A new family tree of the plant genus Solanum helps explain the striking diversity of their fruit color and size. This genus includes tomatoes, potatoes, eggplants, and other economically important plants.
