Aquilops Americanus – Oldest Known Species of Horned Dinosaur from North America

Aquilops Americanus Oldest Horned North American Dinosaur

A team of paleontologists has discovered the oldest known “horned” dinosaur fossil from North America. Named Aquilops americanus, the species is 40 million years older than the iconic Triceratops. A fossil skull small enough to fit in the palm of your hand represents the oldest species of horned dinosaur named from North America. The discovery, […]

Astronomers Detect Pluto-Size Objects around a Sun-Like Star

Astronomers Detect Pluto-Size Objects swarming Around an Adolescent Sun

Using the Atacama Large Millimeter/submillimeter Array, astronomers from the Harvard-Smithsonian Center for Astrophysics have detected Pluto-size objects around an adolescent Sun-like star. Cambridge, Massachusetts – Scientists used the Atacama Large Millimeter/submillimeter Array (ALMA) to make detailed observations of the protoplanetary disk surrounding the star known as HD 107146, detecting an unexpected increase in the concentration […]

Astronomers Detect Magnetic Fields on Solar-Type Stars

Astronomers Study the Magnetic Fields Stars

A team of astronomers that has just completed the most extensive polarization survey of stars to date, detecting magnetic fields on sixty-seven stars with twenty-one of them being classified as solar-type. That is about four times as many solar-type stars as had been previously classified. The Sun rotates slowly, about once every 24 days at […]

New Research Shows Molecular Decoys Help Overcome Drug Resistance

Research Shows Molecular Decoys Help Overcome Drug Resistance

By using molecular fragments administered alongside antimicrobial agents, researchers at Brown University have shown that the efflux pumps are kept busy pumping out the fragments while the antimicrobial agents are able to stay inside the cell. Providence, Rhode Island – Brown University – Harmful bacteria have evolved some ingenious mechanisms to resist antibiotics. One of […]

Intense Volcanism May Have Played a Role in Dinosaurs Extinction

What Really Killed the Dinosaurs

MIT scientists used precisely dated rocks from the Deccan Traps to reveal evidence that a major volcanic eruption began just before the asteroid impact that wiped out the dinosaurs, possibly playing a role in the extinction. Sixty-six million years ago, an asteroid more than five miles wide smashed into the Earth at 70,000 miles per […]

New Dark Matter Detector Will Be 100 Times More Sensitive to Dark Matter

Hunting for Dark Matter in a Gold Mine

A team of scientists is building a supersized version of the dark matter detector Lux, called Lux-Zeplin, which will be roughly 100 times more sensitive to dark matter than its predecessor. “What really impressed me was the trip down,” said astrophysicist James Buckley, PhD, speaking of the vertical mile he traveled to get to the […]

Neuroscientists Reveal Fundamental Discovery about Cortical Neurons

Neuroscientists Reveal Fundamental Discovery about Cortical Neurons

Neuroscientists from the Picower Institute for Learning and Memory uncover a fundamental discovery about cortical neurons, showing that inhibitory neuron functionality is not an immutable property of cortical cells, but a consequence of more complex network dynamics. The two major types of neuron in the brain’s cerebral cortex are connected by intricate cortical circuits that […]

Gene-Editing System Allows Rapid, Large-Scale Studies of Gene Function

Researchers Develop a New Technique to Study Gene Function

Using a gene-editing system that was originally developed to delete specific genes, researchers from MIT developed a new technique to reliably turn on any gene of their choosing in living cells. This new application for the CRISPR/Cas9 gene-editing system should allow scientists to more easily determine the function of individual genes, according to Feng Zhang, […]

Chandra Views Ultraluminous X-Ray Sources

New Chandra Image of NGC 2207 and IC 2163

This new Chandra image shows NGC 2207 and IC 2163, which have hosted three supernova explosions in the past 15 years and have produced one of the most bountiful collections of super bright X-ray lights known. At this time of year, there are lots of gatherings often decorated with festive lights. When galaxies get together, […]

Rosetta Data Reignite Debate on the Origin of Earth’s Oceans

New Research Reignites Debate on Earth's Oceans

The Rosetta spacecraft has discovered that the composition of comet 67P/Churyumov-Gerasimenko’s water vapor is significantly different from that found on Earth, reigniting the debate on the origin of Earth’s oceans. The question about the origin of oceans on Earth is one of the most important questions with respect to the formation of our planet and […]

Millions of Tons of Seafloor Methane Could Be Released

Warmer Pacific Ocean Could Release Seafloor Methane

A new study published in Geophysical Research Letters reveals that warmer Pacific Ocean temperatures could release millions of tons of seafloor methane. Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming […]

Colloidal Quantum Dots Allow Solar Cells to Be Sprayed on Products

Researchers Develop New Technique for Spraying Solar Cells

Using miniscule light-sensitive materials known as colloidal quantum dots, scientists from the University of Toronto have developed new technique for spraying solar cells onto products. Pretty soon, powering your tablet could be as simple as wrapping it in cling wrap. That’s Illan Kramer’s hope. Kramer and colleagues have just invented a new way to spray […]

A Pill to Shed Fat? Researchers Turn White Fat Cells Into Brown Fat Cells

Researchers Turn White Fat Cells into Brown Fat Cells

Scientists from Harvard have created a system using human stem cells to screen for compounds that have the potential to turn white fat cells into brown fat cells. Harvard Stem Cell Institute (HSCI) researchers have taken what they describe as “the first step toward a pill that can replace the treadmill” for the control of […]

Brain’s Response to Smoking is Different in Men and Women

Men and Women Respond Differently to Cigarettes

New research from Yale University shows that men and women respond to cigarettes differently, demonstrating for the first time that smoking-induced dopamine activation occurs in a different brain region and much faster in nicotine-dependent men than women. Yale researchers using a new brain imaging analysis method have confirmed that smoking cigarettes activates a dopamine-driven pleasure […]

New Drug Combination Delays Breast Cancer Progression

New Drug Combination Delays Cancer Progression

Research presented at the 2014 San Antonio Breast Cancer Symposium reveals that a new drug combination for advanced breast cancer delays disease progression. A new combination of cancer drugs delayed disease progression for patients with hormone-receptor-positive metastatic breast cancer, according to a multi-center phase II trial. The findings of the randomized study (S6-03) were presented […]
