Climate Science Literacy Unrelated to Public Acceptance of Human-Caused Global Warming

New research from Yale University shows that climate science literacy is unrelated to public acceptance of human-caused global warming. Deep public divisions over climate change are unrelated to differences in how well ordinary citizens understand scientific evidence on global warming, according to a new study published by Professor Dan Kahan. In fact, members of the […]

Neuroscientists Reveal How Brain Waves Guide Memory Formation

New research from MIT shows that the hippocampus and the prefrontal cortex use two different brain-wave frequencies to communicate as the brain learns to associate unrelated objects. Our brains generate a constant hum of activity: As neurons fire, they produce brain waves that oscillate at different frequencies. Long thought to be merely a byproduct of […]

Life Could Have Flourished on Earth 3.2 Billion Years Ago

New research from the University of Washington found evidence that life was pulling nitrogen out of the air and converting it into a form that could support larger communities 3.2 billion years ago. A spark from a lightning bolt, interstellar dust, or a subsea volcano could have triggered the very first life on Earth. But […]

Nanoscale Cage Could Improve Nanopore Technology

Brown University researchers have designed a nanoscale cage that can trap a single DNA strand and allow before-and-after sequencing of the same DNA strand. Providence, Rhode Island (Brown University) — Despite having a diameter tens of thousands of times smaller than a human hair, nanopores could be the next big thing in DNA sequencing. By […]

Study-Helps-Explain-Comet-Composition

New research from NASA’s Jet Propulsion Laboratory used a cryostat instrument, nicknamed “Himalaya,” to study the icy conditions under which comets form. Astronomers tinkering with ice and organics in the lab may have discovered why comets are encased in a hard, outer crust. Using an icebox-like instrument nicknamed Himalaya, the researchers show that fluffy ice […]

New Research Yields Insight Into Generating Antibodies That Target Different Strains of HIV

New research yields insight into generating antibodies that target different strains of HIV, suggesting that sequentially administering several different forms of a potential HIV vaccine could stimulate a stronger immune response than delivering a cocktail of these variants all at once. Through an investigation of a fundamental process that guides the maturation of immune cells, […]

Analysis Shows How to Prevent Metal Embrittlement

A newly published study from MIT details how certain crystal boundaries can enhance, or reduce, the damaging effects that lead to metal embrittlement. When a metal tube lines an oil well thousands of feet below the surface of the ocean, that metal had better be solid and reliable. Unfortunately, the environment in such deep wells […]

How Raindrops Spread Pathogens Among Plants

A new theoretical model describes the relationship between a leaf’s flexibility, the fragmentation of the fluid, and its resulting pattern of raindrop-induced dispersal. Using high-speed images of raindrops splashing down on leaves, the researchers show that raindrops can act as a dispersing agent of contaminated droplets from one plant to another. Historical weather records suggest […]

Archaeologists Clarify Factors that Contributed to the Demise of Early Rapa Nui Society

Using flakes of obsidian as a dating tool, a newly published study helps clarify the factors that contributed to the demise of early Rapa Nui society. Long before the Europeans arrived on Easter Island in 1722, the native Polynesian culture known as Rapa Nui showed signs of demographic decline. However, the catalyst has long been […]

Study Shows Ribosomal Motor is Crucial Part of Cellular Protein Factory

New research from Yale University provides insights into the conformational space that EF-G samples on the ribosome and reveals that tRNA translocation on the ribosome is facilitated by a structural transition of EF-G from a compact to an elongated conformation, which can be prevented by the antibiotic dityromycin. The ribosome is the protein-making “factory” within […]

Earth’s Earliest Primates Lived in Trees

New research from Yale University reveals that Earth’s earliest primates lived in trees. Earth’s earliest primates have taken a step up in the world, now that researchers have gotten a good look at their ankles. A new study has found that Purgatorius, a small mammal that lived on a diet of fruit and insects, was […]

New Exoplanet-Hunting Telescopes

The Next-Generation Transit Survey has achieved first light and will focus on discovering Neptune-sized and smaller planets, with diameters between two and eight times that of Earth. The Next-Generation Transit Survey (NGTS) is a wide-field observing system made up of an array of twelve telescopes, each with an aperture of 20 centimeters [1]. This new […]

Why Some Crystals Jump and Others Crumble

A team of researchers has discovered the force that makes the organometallic compound palladium hexafluoroacetylacetonate jump. This thermosalient effect could potentially be applied in artificial muscles and actuators. Crystals are not as stationary as you might think. A crystal of an organometallic compound containing palladium, for example, downright jumps from a hotplate once it reaches […]

Study Pinpoints Autism-Linked Protein for Sculpting Brain Connections

A new study from Duke University provides a close-up of synapse refinement and identifies that the protein hevin is crucial in this process. Durham, North Carolina – Shortly after birth, human brains expand rapidly with the experience of an entirely new world. During this period, neurons in the newborn brain compete with one another to […]

Controlling Chemical Binding Properties Improves Structurally Complex Materials like Concrete

Using sophisticated calculations that show how atomic-level forces affect the mechanical properties of a complex particle-based material, researchers from Rice University reveal new ways to improve the chemistry of materials like concrete to make it less prone to cracking and more suitable for specific applications. Even when building big, every atom matters, according to new […]

Schizophrenia Onset Linked to Elevated Neural Links

New research from Yale scientists, in conjunction with colleagues at the Huaxi Magnetic Resonance Research Center at Sichuan University in China, reveals that that the onset of the schizophrenia is marked by an abnormal spike in neural connections. In its chronic stage, schizophrenia is typically marked by a dearth of links between brain cells in […]
