Collaborators have created 'living-like' bioactive interior architecture designed to one day protect us from hidden airborne threats. This publication establishes that the lab's biomaterial manufacturing process is compatible with the leading-edge cell-free engineering that gives the bioactive sites their life-like properties.

Engineers have developed a cost-effective and environmentally friendly way to remove heavy metals, including copper and zinc, from biosolids. The team's work advances other methods for heavy-metal removal by recycling the acidic liquid waste that is produced during the recovery phase, instead of throwing it away.

Tidal range schemes are financially viable and could lower energy bills say researchers. Research combined a tidal range power generation model with its cost model to demonstrate the viability of tidal power. The research demonstrates the benefits of tidal energy, which does not suffer from unpredictable intermittency as power is generated both day and night, and in windy or calm weather. The creation of a tidal barrage could operate for 120 years or more to meet future demand and storage problems.

Engineers are placing low-powered sensors in the reflective raised pavement markers that are already used to help drivers identify lanes. Microchips inside the markers transmit information to passing cars about the road shape to help autonomous driving features function even when vehicle cameras or remote laser sensing, called LiDAR, are unreliable because of fog, snow, glare or other obstructions.

Anything with three hearts, blue blood and skin that can change colors like a display in Times Square is likely to turn heads. Meet Sepia bandensis, known more descriptively as the camouflaging dwarf cuttlefish. Over the past three years, neuroscientists have put together a brain atlas of this captivating cephalopod: a neuroanatomical roadmap depicting for the first time the brain's overall 32-lobed structure as well its cellular organization.

Researchers are leading an international team whose goal is to create a framework to help governments in the U.S. and around the world assess and prioritize remediation strategies for orphaned oil and gas wells. These inactive wells represent environmental risks since they have the potential to contaminate water supplies, degrade ecosystems, and emit methane and other air pollutants that are harmful to human health. But plugging the wells also offers various potential environmental opportunities such as underground storage of carbon dioxide and hydrogen, or the development of geothermal energy systems.

Scientists have developed a magnetically controlled soft medical robot with a unique, flexible structure inspired by the body of a pangolin. The robot is freely movable despite built-in hard metal components. Thus, depending on the magnetic field, it can adapt its shape to be able to move and can emit heat when needed, allowing for functionalities such as selective cargo transportation and release as well as mitigation of bleeding.

Some animals release chemical pheromones which can trigger behavioral or hormonal changes in other animals. It is known that calm rats can reduce the fear of nearby rats, but the exact mechanism was unknown. Researchers have found the pheromone responsible and demonstrated its effect both on lab rats and rats in the human environment. Their findings could lead to a new kind of humane pest control.

New research has revealed that well-functioning ecosystems are crucial to human health and wellbeing, with human-biodiversity interactions delivering wellbeing gains equating to substantial healthcare cost-savings, when scaled-up across populations.

To conserve precious and fragile biodiversity hotspots, a crucial step is knowing how the fruit eaters are doing. To assist in that, scientists and students have supersized a database to keep track of such animals and birds.

A detailed, high-resolution map of the rusty patched bumble bee's genome has been released, offering new approaches for bringing the native pollinator back from the danger of extinction. Putting together the rusty patched bumble bee genome is part of the Beenome 100 project, a first-of-its-kind effort to create a library of high-quality, highly detailed genome maps of 100 or more diverse bee species found in the United States.

Trajectory of irrigation water use in many regions is unsustainable, but practice is vital in managing climate change and future agricultural development, researchers conclude.

In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.

The Intergovernmental Panel on Climate Change Fifth Assessment Report (AR5), released just prior to an international climate convention in 2015, explicitly stated that human-caused greenhouse gas emissions were the highest in history, with clear and widespread impacts on the climate system. Since then, hundreds of cities across the world have published their own climate action plans (CAPs), detailing how their urban areas will handle climate change. How do the plans stack up against one another and against the recommended guidelines established by the United Nations-Habitat Guiding Principles for City Climate Action Planning?
