Mitochondria have a waste disposal mechanism to get rid of mutated mtDNA
Scientists at the University of Cologne have discovered how cells can eliminate mutated mitochondrial DNA (mtDNA). Due to their evolutionary descent from bacteria, mitochondria still have genetic material packaged in chromosome-like structures (nucle.....»»
Mechanism behind autophagy trigger unveiled
An international research team led by Osaka University has identified a new mechanism crucial for the initiation of autophagy, a self-degradation process cells use to eliminate unneeded or damaged components. In recent years, autophagy has also been.....»»
Researchers are commercializing technology to turn waste into plastic-free, biodegradable packaging

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.....»»
Researchers identify novel endocytic recycling mechanism with "kiss-and-run" membrane fusion
Endocytosis and recycling control the uptake and retrieval of various materials in eukaryotic cells. Mammalian cells have developed several recycling routes, including the relatively extensively studied "fast" and "slow" tubulovesicular recycling pat.....»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
Recharging mitochondria—nanoflowers offer a new way to simulate energy production to improve aging ailments
When we need to recharge, we might take a vacation or relax at the spa. But what if we could recharge at the cellular level, fighting against aging and disease with the microscopic building blocks that make up the human body?.....»»
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......»»
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......»»
New mechanism uncovered for the reduction of emu wings
.Researchers have uncovered a novel mechanism underlying the skeletal reduction and asymmetry of emu wings. Their research reveals that the absence of distal muscle formation results in a lack of mechanostress during development, leading to the obser.....»»
Data disposal and cyber hygiene: Building a culture of security within your organization
Data breach episodes have been constantly rising with the number of data breach victims crossing 1 billion in the first half of 2024. A recent Data Breach Report 2023 by Verizon confirms that 74% of data breaches are due to human errors. Although cyb.....»»
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......»»
AI Could Help Save Us from Conspiracy Theories, and Massachusetts Could Help Save Us from Our Trash
AI fights conspiracy theories, Massachusetts leads the way on waste reduction, and more in this week’s science news roundup.....»»
Scientists discover nonstomatal control of water loss in critical crops
Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism—tiny pores known as stomata......»»
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......»»
