Scientists Create the First 3D Maps of Entire Folded Genomes

The First High-Resolution 3D Maps of Entire Folded Genomes

A team of researchers has created the first 3D maps of entire folded genomes, identifying approximately 10,000 folding loops in the human genome. In a triumph for cell biology, researchers have assembled the first high-resolution, 3-D maps of entire folded genomes and found a structural basis for gene regulation, a kind of “genomic origami” that […]

Valleytronics Help Researchers Move Toward a New Kind of 2D Microchip

A New Kind of 2D Microchip

Using an approach called valleytronics, a team of researchers has cleared hurdles toward a new kind of 2D microchip that uses different electron properties. New findings from a team at MIT and other institutions could provide a pathway toward a kind of two-dimensional microchip that would make use of a characteristic of electrons other than […]

New Map of Mars Shows Signs of Ancient Lakes and Quakes

Signs of Ancient Mars Lakes and Quakes Seen in New Map

A new geological map based on NASA images shows signs of ancient lakes and quakes on Mars. This animation simulates a flyover of a portion of a Martian canyon detailed in a geological map produced by the U.S. Geological Survey and based on observations by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter. The landforms […]

Hubble Image of the Week: Dwarf Galaxy Markarian 209

New Hubble Image of Dwarf Galaxy Markarian 209

This newly released Hubble image shows dwarf galaxy Markarian 209. This sprinkle of cosmic glitter is a blue compact dwarf galaxy known as Markarian 209. Galaxies of this type are blue-hued, compact in size, gas-rich, and low in heavy elements. They are often used by astronomers to study star formation, as their conditions are similar […]

Scientists Use Real Data to Measure the Cosmos

Researchers Use Real Data to Measure the Cosmos

Scientists from the Imperial College London have used data, rather than calculations related to general relativity, to measure large distances in the Universe for the first time. A research team from Imperial College London and the University of Barcelona has used data from astronomical surveys to measure a standard distance that is central to our […]

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, […]

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 […]
