Controlling the length of supramolecular polymers
Systems made up of one supramolecular polymer are well understood, but much remains unknown for systems involving the combination of multiple supramolecular polymers, such as what affects the length of the resulting copolymers. For her Ph.D. research.....»»
Researchers discover Gulf Stream thermal fronts controlling North Atlantic subtropical mode water formation
Subtropical mode water (STMW) is a vertically homogeneous thermocline water mass, serving as heat, carbon, and oxygen silos in the ocean interior and providing memory of climate variability for climate prediction. Understanding physics governing STMW.....»»

Varroa mites and deformed wing virus make honeybees more susceptible to insecticides
Controlling for Varroa mites, the parasitic mites that feed on honey bees and serve as vectors for viral diseases like deformed wing virus (DWV), can help with improving honeybee populations and make bees less susceptible to harmful insecticides, acc.....»»
Discovery of novel primitive xeno nucleic acids as alternative genetic polymers adds piece to origin of life puzzle
The chemical origin of life on Earth is a puzzle that scientists have been trying to piece together for decades. Many hypotheses have been proposed to explain how life came to be and what chemical and environmental factors on early Earth could have l.....»»
Brazilian fossil provides earliest evidence of evolutionary trait that enabled dinosaurs to become giants
The missing link has just been found between the earliest dinosaurs, whose size ranged from a few centimeters to at most three meters in length, and more recent giants that could be more than twice the length of a bus and have so much appeal to the p.....»»
Backpack-wearing chickens are helping change the way we study animal welfare
The chicken sheds I conduct research in are enormous—over three-quarters the length of a football field and 20 meters wide. In each house, around 28,000 near-identical broiler chickens, which are the type we use for meat, are reared in six-week pro.....»»
A new approach to controlling the properties of turbulence
Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating it and controlling its pro.....»»
Trojan Horse polymers for a circular economy: New strategy for recyclable polyolefins
It is hard to imagine our daily lives without plastics made out of polyolefins. Unfortunately, practical methods for recycling of polyolefins are lacking. In the journal Angewandte Chemie, a research team has now introduced a new approach for making.....»»
