Redefining Our Bond with Plants: Wearable Textiles That Grow
Humans have long approached plants from a utilitarian perspective—primarily as sources of food or raw materials. But researchers at Cornell University’s College of Human Ecology (CHE) are exploring a different kind of relationship, one that views plants not as tools but as companions. Through an inn...

Ancient Cicada Fossil from Messel Pit Sheds Light on Insect Evolution
A fossilized true cicada has been described for the first time from Germany’s Messel Pit, offering valuable insight into the evolutionary history of one of the most species-rich insect families. The newly identified species, Eoplatypleura messelensis, is not only one of the oldest known true cicadas...

Scientists Map the Complete Evolutionary History of All Known Bird Species
Professor Emily Jane McTavish and a team from the Cornell Lab of Ornithology have created the most comprehensive evolutionary tree of birds to date, charting the relationships among every known bird species. Drawing from nearly 300 studies published between 1990 and 2024, the researchers combined da...

Innovative Composting System Turns Agricultural Waste into Sustainable Biofertilizer
The intensification of global agriculture has led to massive waste production, including an estimated 14 billion tons of crop straw and 125 million tons of livestock manure annually. Traditional composting methods often fall short due to poor breakdown of lignocellulose and the persistence of harmfu...

Jurassic Tree Climber: Fossil Study Reveals Marmoretta Lived in the Canopy, Not the Water
The 166-million-year-old reptile Marmoretta oxoniensis has long been thought to have lived a semi-aquatic lifestyle, swimming through ancient lagoons. But new research is turning that idea on its head—literally. Using cutting-edge scanning technologies, scientists now believe Marmoretta was a tree-d...

Advancing Quantum Dot Solar Technology with Low-Cost Ink Engineering
Colloidal quantum dots (CQDs) are ultra-small semiconductor crystals, just a few nanometers wide, synthesized in liquid solutions. These single-crystal particles, formed through chemical and physical breakdown of bulk materials, hold significant promise for photovoltaic (PV) technology due to their ...
