Pushing frontiers through upcycling: Eggshell waste for bone graft material
Autologous and allogeneic bone grafts are considered the gold standard when it comes to reconstructing bones, largely due to their bioactive compounds and osteoblastic cells that can generate new bone effectively. However, limited supply, donor-site.....»»
Observations confirm that early-universe quasar neighborhoods are densely populated with companion galaxies
Quasars are the most luminous objects in the universe and are powered by material accreting onto supermassive black holes at the centers of galaxies......»»
From pollution to power: Merging wastewater treatment and energy generation with capacitive MFC innovations
Imagine standing on the edge of a new frontier, where waste—something we often view as a problem—becomes the solution. We live in a world that needs innovation, where environmental challenges demand a sustainable approach, and where we need techn.....»»
X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
Tested: Shokz OpenRun Pro 2 bone-conduction wireless headphones
I’ve long used Shokz bone-conduction wireless headphones as my go-to for voice and video calls, mostly because they are so comfortable I often forget I’m wearing them. I’ve been using the OpenComm model for a couple of years now, but switche.....»»
Forever chemicals persist through waste incineration, researcher finds
PFAS, often called "forever chemicals," present in municipal solid waste can survive the high temperatures of waste incineration and continue to spread into the environment via residues from waste-to-energy plants......»»
New material with wavy layers of atoms exhibits unusual superconducting properties
MIT physicists and colleagues have created a new material with unusual superconducting and metallic properties, thanks to wavy layers of atoms only billionths of a meter thick that repeat themselves over and over to create a macroscopic sample that c.....»»
Scientists track plastic waste in pristine Canada marine park
Old tires, discarded cups, and cigarette butts litter the magnificent Saguenay Fjord, a marine protected area in eastern Canada that attracts belugas and other whales seeking respite......»»
How plastic pollution poses challenge for Canada marine conservation
One of the largest producers of plastic waste per capita, Canada is struggling to protect its designated marine protected areas from this pollution, experts warn......»»
Independent origins of frog glue and its role in predator evasion
Skin-secreted adhesives, or glues, are highly effective defense adaptations that have evolved recurrently in a small number of amphibians. From an ecological standpoint, this rapidly solidifying material—essentially, a sticky slime—encumbers the.....»»
Researchers explore physiological and molecular processes underlying graft healing
Grafting has long been a cornerstone in agriculture and forestry, allowing for the propagation of desirable plant traits and improved resistance to environmental challenges. Despite its widespread application, grafting still encounters obstacles, inc.....»»
Bioengineers create new substrate to study wood-decomposing enzyme
Researchers want to transform the natural and abundant resource wood into useful materials, and central to that is a molecular machine found in fungi that decomposes the complex raw material into its basic components......»»
Template synthesis creates multilayered perovskites with unique ferroelectric behavior
A group of Nagoya University researchers in Japan has synthesized 4- and 5-layered versions of the important electrical material perovskite. Analyzing the mechanism of ferroelectricity in the material, they found it has a unique function: the materia.....»»
So where does the oceans" plastic waste come from?
In the form of bottles, tires, packaging and piping, millions of tons of plastic waste are dumped every year in the world's waterways, often ending up in the oceans......»»

Tiny robots and AI algorithms could help to craft material solutions for cleaner environments
Many human activities release pollutants into the air, water and soil. These harmful chemicals threaten the health of both people and the ecosystem. According to the World Health Organization, air pollution causes an estimated 4.2 million deaths annu.....»»
Study sheds light on trade-off between noise and power in nanoscale heat engines
Thanks to nanoscale devices as small as human cells, researchers can create groundbreaking material properties, leading to smaller, faster, and more energy-efficient electronics. However, to fully unlock the potential of nanotechnology, addressing no.....»»
Video: Why Canadian trash costs $30,000 per gram
How do you turn nuclear waste into a $30,000-per-gram commodity? Tritium, once discarded as a by-product of Canadian nuclear reactors, is now one of the most expensive materials on Earth. This rare isotope of hydrogen powers glow-in-the-dark keychain.....»»
"Easy, convenient, cheap": how single-use plastic rules the world
Each year the world produces around 400 million tonnes of plastic waste, much of it discarded after just a few minutes of use......»»
Printed engines propel the next industrial revolution
In the fall of 2023, NASA hot fire tested an aluminum 3D printed rocket engine nozzle. Aluminum is not typically used for 3D printing because the process causes it to crack, and its low melting point makes it a challenging material for rocket engines.....»»
Multifunctional phosphor developed for white LED lighting and optical thermometry
