Breaking the Mold: Bioplastic Pellets Offer Hope in the Fight Against Plastic Pollution

A promising alternative to traditional plastic may have emerged, bringing hope in the battle against plastic pollution. Researchers have unveiled newly developed “bioplastic” pellets, offering a sustainable option that could surpass the environmental impact of current plastic materials used in bottles and various objects.

Published in RCS Sustainability, a recent paper sheds light on the potential of these pellets, which serve a dual purpose. Not only do they function as absorbents, effectively extracting phosphate from water—a critical step in addressing global water security concerns—but they also hold promise as agricultural fertilizer, providing a sustainable solution to nutrient depletion in soil.

Shedding Light on Evaporation: A Groundbreaking Discovery

Evaporation, the ubiquitous process of water transforming into vapor, has long been attributed solely to heat. However, groundbreaking research from MIT reveals a previously overlooked factor: light. In a series of meticulous experiments, scientists have demonstrated that light striking the interface between air and water can trigger evaporation independently of heat.

Published in the Proceedings of the National Academy of Sciences, the study by Professor Gang Chen and his team unveils a phenomenon dubbed the “photomolecular effect.” This effect, observed when light interacts with water molecules at the surface, leads to their liberation into the air, challenging the conventional understanding of evaporation.

Unveiling the Early Childhood Cognitive Nexus: Stunting’s Impact on Visual Working Memory

A groundbreaking collaboration spearheaded by Professor John Spencer from the University of East Anglia and Assistant Professor Samuel Forbes from the esteemed Psychology Department has uncovered a pivotal connection, affecting infants as young as six months old. This correlation links the physical stature of infants to their cognitive abilities, intricately tied to brain function. The joint effort, which also involved the University of Nottingham, the Community Empowerment Lab, University of Iowa, Rhode Island Hospital, Brown University, and the Bill & Melinda Gates Foundation, represents a significant stride forward in comprehending early childhood development.

Central to this research is the concept of ‘visual working memory,’ a fundamental aspect of our cognitive framework responsible for maintaining and processing visual information. The study meticulously compared this cognitive capacity in infants experiencing stunted growth—a telltale sign of undernutrition and adverse environmental conditions—with their peers exhibiting expected growth patterns. The study’s findings are striking, revealing that infants with stunted growth display disrupted visual working memory, rendering them more susceptible to distractions. This poses a worrying precedent for their cognitive development, indicating a potentially diminished trajectory in the year ahead.

Stem Cell Breakthrough Paves the Way for Woolly Mammoth De-Extinction

Colossal Biosciences has announced a significant breakthrough in stem cell research that could propel efforts to resurrect long-extinct woolly mammoths. According to a statement shared with Live Science, Colossal’s Woolly Mammoth team has successfully derived induced pluripotent stem cells (iPSCs) from Asian elephants (Elephas maximus). iPSCs, capable of transforming into any cell type in the body, provide researchers with a crucial tool to explore the genetic makeup and unique adaptations of woolly mammoths.

Eriona Hysolli, head of biological sciences and mammoth lead at Colossal Biosciences, emphasized the significance of this achievement in understanding the genetic and cellular mechanisms behind the distinctive features of woolly mammoths. iPSCs offer insights into traits such as shaggy hair, curved tusks, fat deposits, and cranial morphology that enabled mammoths to thrive in Arctic environments. Moreover, iPSCs pave the way for generating elephant sperm and egg cells in the lab, circumventing the challenges of harvesting cells from endangered Asian elephants.

Deciphering Chicken Clucks: Humans Can Detect Emotions in Chicken Vocalizations

A study led by the University of Queensland has unveiled a fascinating ability in humans – the capability to discern whether chickens are excited or displeased based solely on the sounds of their clucks. Professor Joerg Henning, hailing from UQ’s School of Veterinary Science, spearheaded the research, which delved into whether humans could accurately interpret the context of calls or clucking sounds produced by domestic chickens, one of the world’s most widely farmed species.

Study Methodology and Key Findings

Professor Henning explained the study’s methodology, saying, “In this study, we used recordings of chickens vocalizing in all different scenarios from a previous experiment.” The researchers identified four distinct call types, each associated with specific contexts:

See-Through Wood: A Sustainable Future Material

Three decades ago, German botanist Siegfried Fink pioneered a revolutionary concept: creating transparent wood by bleaching plant cells. His breakthrough technique, published in a 1992 wood technology journal, remained dormant until materials scientist Lars Berglund stumbled upon it, sparking a renewed interest in transparent wood. Collaborating with researchers at the University of Maryland, Berglund and his counterparts at KTH Royal Institute of Technology in Sweden have now harnessed the potential of transparent wood for various applications.

Wood’s intricate structure consists of vertical channels resembling bundled straws held together by glue called lignin. To achieve transparency, researchers remove or modify lignin, leaving a milky-white skeleton of hollow cells. By filling these cells with a substance like epoxy resin that bends light similarly to cell walls, transparent wood is created. Despite its thin profile, transparent wood exhibits remarkable strength, outperforming plastic and glass in fracture and pressure tests.

Scientists reproduced a gravity field- 1,000 times stronger than Earth’s gravity

The study overcomes the effects of Earth’s gravity, replicating conditions on other planets, stars.

A recent discovery has shed new light on one of the most intriguing phenomena in the universe. Astronomers have found an incredibly strong gravity field, approximately 1,000 times more potent than Earth’s gravity, surrounding a rare type of neutron star known as a magnetar.

The magnetar in question is located approximately 30,000 light-years away from Earth and was discovered by a team of scientists from the University of Amsterdam and the University of Cambridge. The researchers used observations from the European Space Agency’s XMM-Newton satellite to measure the strength of the magnetar’s gravity field.

‘Mind-boggling’ alloy is Earth’s toughest material, even at extreme temperatures

A metallic alloy of chromium, cobalt, and nickel is over 100 times tougher than graphene and gets even more resistant to damage at extremely low temperatures.

Researchers have proven that a metallic alloy of chromium, cobalt and nickel is officially the toughest material on Earth — more than 100 times tougher than the wonder material graphene.

In a new study published Dec. 1 in the journal Science, researchers subjected the ultra-tough alloy to extremely cold temperatures, in order to test how fracture-resistant the material is. Scientists have known for years that this alloy is one tough cookie — however, to the team’s surprise, the alloy only became tougher and more resistant to cracks as temperatures plummeted. 

This super-resistance to fracture is in stark contrast to most materials, which only become more brittle in freezing temperatures, according to the study authors.

“People talk about the toughness of graphene, and that is measured at just 4 megapascals per meter,” study co-author Robert Ritchie), a professor of engineering at the University of California Berkeley and senior faculty scientist at the Lawrence Berkeley National Laboratory, told Live Science. “The toughness of aluminum alloys used in aircraft is 35 megapascals per meter. This material has a toughness of 450 to 500 megapascals per meter… these are mind-boggling numbers.” 

The potential applications of such a tough material range from space infrastructure to fracture-resistant containers for clean energy uses here on Earth. However, Ritchie noted, two of the alloy’s three elements (nickel and cobalt) are prohibitively expensive, limiting the alloy’s usefulness to the laboratory for the foreseeable future.
