New understanding of astatine"s chemical properties could aid targeted alpha therapy for cancer
Astatine is one of the least-studied elements of the periodic table, because all isotopes of astatine are unstable, with the longest half-life barely exceeding 8 hours. Thus, only radiochemists at the production facilities (limited worldwide) can hav.....»»
Simulating blood flow dynamics for improved nanoparticle drug delivery
Despite gaining a bad rap in mainstream media in recent years, nanoparticles have been successfully used for decades in targeted drug delivery systems. Drug molecules can be encapsulated within biodegradable nanoparticles to be delivered to specific.....»»
First comprehensive characterization of the extraordinary thermoelectric properties of cadmium arsenide thin films
If there's one thing we humans are good at, it's producing heat: significant amounts, and in many cases most of the energy we generate and put into our systems we lose as heat, whether it be our appliances, our transportation, our factories, even our.....»»
Scientists use computational modeling to guide a difficult chemical synthesis
Researchers from MIT and the University of Michigan have discovered a new way to drive chemical reactions that could generate a wide variety of compounds with desirable pharmaceutical properties......»»
Lucy, discovered 50 years ago in Ethiopia, still towers over our understanding of human origins
In 1974, on a survey in Hadar in the remote badlands of Ethiopia, U.S. paleoanthropologist Donald Johanson and graduate student Tom Gray found a piece of an elbow joint jutting from the dirt in a gully. It proved to be the first of 47 bones of a sing.....»»
Gold nanoparticles kill cancer—but not as thought
Gold particles of the size of billionths of a meter are lethal to cancer cells. This fact has been known for a long time, as has a simple correlation: The smaller the nanoparticles used to fight the cancer cells, the faster they die. However, a more.....»»
Most pristine trilobite fossils ever found shake up scientific understanding of the long extinct group
Researchers have described some of the best-preserved three-dimensional trilobite fossils ever discovered. The fossils, which are more than 500 million years old, were collected in the High Atlas of Morocco and are being referred to by scientists as.....»»
Teaching biology—no more stressing out over structural formulas
Structural formulas are a source of dread for many students, but they're an essential tool in biology lessons. A joint study has shown that the stress levels of students working with chemical formulas are significantly reduced if they are given simpl.....»»
Aging Might Not Be Inevitable
There are biological underpinnings to aging—and so researchers are investigating cell manipulations, transfusions of young blood, and chemical compounds that can mimic low-calorie diets......»»
Scientists uncover previously unknown properties of gallium
Nearly 150 years after gallium was discovered and added to the periodic table, University of Auckland scientists have uncovered previously-unknown aspects of the metal's structure and behavior......»»
Exciting applications for marine degradable, bio- and CO2-based PISOX polymers
Researchers at the Industrial Sustainable Chemistry (ISC) group at the Van 't Hoff Institute for Molecular Sciences have developed a new class of bio- and CO2 based PISOX polymers with surprising properties and applications......»»
New method visualizes ligands on gold nanoparticles in liquid
The University of Antwerp and CIC biomaGUNE have come up with a promising method for understanding the role of surface molecules in the formation of nanoparticles. The groundbreaking research, published in Nature Chemistry, provides an advanced chara.....»»
Re-analyzing LHC Run 2 data with cutting-edge analysis techniques allowed physicists to address old discrepancy
Supersymmetry (SUSY) is an exciting and beautiful theory that answers some of the open questions in particle physics. It predicts that all known particles have a "superpartner" with somewhat different properties. For example, the heaviest quark of th.....»»
Researchers create green solvent to boost lignin applications
Lignin, the glue that holds fibers together in trees and plants, is one of the most common yet one of the most complex biocomposites, because there are so many variants and qualities. Its heterogeneous chemical structure makes it difficult to investi.....»»

Quantum observers, migrating mangroves, the deep history of an asteroid and understanding appetite in this issue of Scientific American.....»»
Advanced Meditation Alters Consciousness and Our Basic Sense of Self
An emerging science of advanced meditation could transform mental health and our understanding of consciousness.....»»
People Who Are Fat and Healthy May Hold Keys to Understanding Obesity
“Heavy and healthy” can be a rare or common condition. But either way it may signal that some excess weight is just fine.....»»
Mars Sample Return Will Change How We See Life on Earth
Despite an eye-watering price tag, bringing pieces of Mars back to Earth promises to revolutionize our understanding of life’s place in the early solar system.....»»
Unlocking the world of bacteria—researchers introduce new approach to make bacteria amenable to genetic engineering
Bacteria populate virtually every habitat on Earth, including within and on our own bodies. Understanding and engineering bacteria can lead to new methods for diagnosing, treating, and preventing infections. Additionally, it presents opportunities to.....»»
Wondershare Filmora: Understanding the Gen Z talent shaping influencer culture
