There are very few animals as important to our world as honeybees. There is, of course, the delicious honey they produce, but they are also essential in maintaining food security and the biodiversity that is threatened by climate change and becoming our strongest natural defense against it.

But with the planet facing a -induced loss of , what happens when honeybees die?

New Northeastern University research, published in Communications Biology, aims to help address the impending biodiversity crisis. The researchers say they have found a new strategy for restoring lost biodiversity by, essentially, identifying the equivalent of a honeybee in different ecosystems and reintroducing it into a particular collapsing ecosystem.

The work demonstrates control over key properties leading to better performance.

MIT researchers and colleagues have demonstrated a way to precisely control the size, composition, and other properties of nanoparticles key to the reactions involved in a variety of clean energy and environmental technologies. They did so by leveraging ion irradiation, a technique in which beams of charged particles bombard a material.

They went on to show that nanoparticles created this way have superior performance over their conventionally made counterparts.

Researchers from the Helmholtz-Zentrum Dresden-Rossendorf and Dresden University of Technology have unraveled the water adsorption mechanism in certain microporous materials—so-called hierarchical metal-organic frameworks (MOFs)—while probing them on the atomic scale.

Discovered only about 25 years ago, their special properties quickly led to a reputation as “miracle materials”—which, as it turned out, can even harvest water from air. The researchers describe how the material achieves this in ACS Applied Materials & Interfaces.

“These very special materials are highly porous solids made of metals or metal-oxygen clusters which are connected in a modular way by pillars of organic chemicals. This 3D arrangement leads to networks of cavities reminiscent of the pores of a kitchen sponge. It is precisely these cavities that we are interested in,” says Dr. Ahmed Attallah of HZDR´s Institute of Radiation Physics.

Georgia Tech engineers are working to make fertilizer more sustainable—from production to productive reuse of the runoff after application—and a pair of new studies is offering promising avenues at both ends of the process.

In one paper, researchers have unraveled how , water, carbon, and light can interact with a catalyst to produce ammonia at and pressure, a much less energy-intensive approach than current practice. The second paper describes a stable catalyst able to convert waste back into nonpolluting nitrogen that could one day be used to make new fertilizer.

Significant work remains on both processes, but the senior author on the papers, Marta Hatzell, said they’re a step toward a more sustainable cycle that still meets the needs of a growing worldwide population.

Unless it is augmented with graphene, watching concrete dry might not be the most thrilling activity. Graphene was initially isolated in 2004 by scientists at The University of Manchester and has become iconic in materials research, with applications ranging from energy storage and water filtering to transportation and construction, including concrete.

A new future for cement is being facilitated by graphene. Soon, everyone will have the option to select the color, texture, and features that they want very soon. More significantly, though, and even more so than its practicality and beauty, the increasing global sustainability movement is rekindling interest in the possibilities of concrete enriched with graphene.

The building sector is confronted with a plethora of obstacles in light of Net Zero aims, and a viable path toward progress could be through the extensive integration of cutting-edge materials. Cement production accounts for 8–10% of worldwide CO2 emissions, making it one of the industries with the largest carbon footprints.

V-Space (official site) is a startup that built Korea’s first UAM (Urban Air Transportation) destined to transport people or payloads of up to 120 Kg with their eVTOL all-electric vehicle. As its name indicates, it is a Vertical Take Off and Landing vehicle using a quad-copter design. It has a seat for one person and looks like a drone-like small helicopter.

EVTOL can fly over a 40-mile distance at a maximum speed of 60 Mph, a little bit below most U.S highway’s speed limits. Of course, the main advantage here is the lack of traffic jams, especially in an emergency.

However, the company has a hot new design called V Speeder-X, which looks a lot more modern and aerodynamic. The payload capacity is 230 Kg, but the speed has increased to 50 Mph as one of the use cases is to use the drone as an ambulance. Note that the flight time is relatively short, with about ~20 minutes.
