319-million-year-old fish preserves the earliest fossilized brain of a backboned animal      (via sciencedaily.com) 

The CT-scanned skull of a 319-million-year-old fossilized fish, pulled from a coal mine in England more than a century ago, has revealed the oldest example of a well-preserved vertebrate brain.

Over 4% of summer mortality in European cities is attributable to urban heat islands      (via sciencedaily.com)     Original source 

Over four percent of deaths in cities during the summer months are due to urban heat islands, and one third of these deaths could be prevented by reaching a tree cover of 30%, according to a modelling study. The study results, obtained with data from 93 European cities, highlight the substantial benefits of planting more trees in cities to attenuate the impact of climate change.

Fishing in synchrony brings mutual benefits for dolphins and people in Brazil, research shows      (via sciencedaily.com) 

By working together, dolphins and net-casting fishers in Brazil each catch more fish, a rare example of an interaction by two top predators that is beneficial to both parties, researchers have concluded following 15 years of study of the practice.

This groundbreaking biomaterial heals tissues from the inside out      (via sciencedaily.com) 

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

A fairy-like robot flies by the power of wind and light      (via sciencedaily.com) 

The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?

AI technology generates original proteins from scratch      (via sciencedaily.com) 

Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.

What crocodile DNA reveals about the Ice Age      (via sciencedaily.com) 

What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers discovered that while changing temperatures and rainfall had little impact on the crocodiles' gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

First computational reconstruction of a virus in its biological entirety      (via sciencedaily.com) 

A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a 'live' virus.

Forests face fierce threats from multiple industries, not just agricultural expansion      (via sciencedaily.com) 

Intact forests are important climate regulators and harbors of biodiversity, but they are rapidly disappearing. Agriculture is commonly considered to be the major culprit behind forest loss, but the authors of a new article show that agriculture isn't solely to blame. For forest loss associated with the 2014 world economy, over 60% was related to final consumption of non-agricultural products, such as minerals, metals and wood-related goods, and the authors argue that we must consider international trade markets when designing conservation strategies.

Collision risk and habitat loss: Wind turbines in forests impair threatened bat species      (via sciencedaily.com) 

In order to meet climate protection goals, renewable energies are booming -- often wind power. More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites. Thus, forests are coming into focus as potential sites. A scientific team has now demonstrated that wind turbines in forests impair endangered bat species: Common noctules (Nyctalus noctula), a species with a high risk of colliding with rotor blades, are attracted to forest wind turbines if these are located near their roosts. Far from roosts, common noctules avoid the turbines, essentially resulting in a loss of foraging space and thus habitat for this species.

Parasitic mites' biting rate may drive transmission of Deformed wing virus in honey bees      (via sciencedaily.com) 

Varroa destructor is an ectoparasitic mite that can cause European honey bee colonies to collapse by spreading Deformed wing virus as they feed. A study suggests a relatively small number of mites can contribute to a large number of infected bees.

Our future climate depends partly on soil microbes -- but how are they affected by climate change?      (via sciencedaily.com)     Original source 

The largest terrestrial carbon sink on Earth is the planet's soil. One of the big fears is that a warming planet will liberate significant portions of the soil's carbon, turning it into carbon dioxide (CO2) gas, and so further accelerate the pace of planetary warming. A key player in this story is the microbe, the predominant form of life on Earth, and which can either turn organic carbon -- the fallen leaves, rotting tree stumps, dead roots and other organic matter -- into soil, or release it into the atmosphere as CO2. Now, an international team of researchers has helped to untangle one of the knottiest questions involving soil microbes and climate change: what effect does a warming planet have on the microbes' carbon cycling?

Blowing bubbles among echidna's tricks to beat the heat      (via sciencedaily.com)     Original source 

Research into how echidnas might respond to a warming climate has found clever techniques used by the animal to cope with heat, including blowing bubbles to wet its nose tip, with the moisture then evaporating and cooling its blood.
