Pupil Diameter Linked to Task Performance

Pupil Diameter Predicts Task Performance

Researchers from the Yale School of Medicine reveal how changes in the activity of individual neurons during performance of a task correspond exactly to the diameter of the pupil, showing signatures of high arousal for a wide diameter and low arousal for a small diameter. If you want to know who is ready to perform […]

Cassini Image: Tethys ‘Eyes’ Saturn

Cassini Image Shows Craters on Tethys

This newly released image from the Cassini Spacecraft shows two large craters on Saturn’s moon Tethys. The two large craters on Tethys, near the line where day fades to night, almost resemble two giant eyes observing Saturn. The location of these craters on Tethys’ terminator throws their topography into sharp relief. Both are large craters, […]

Hubble Views Irregular Blue Compact Dwarf Galaxy UGC 11411

Hubble Image of Irregular Blue Compact Dwarf Galaxy UGC 11411

This newly released Hubble image shows irregular blue compact dwarf (BCD) galaxy UGC 11411. BCD galaxies are about a tenth of the size of a typical spiral galaxy such as the Milky Way, and are made up of large clusters of hot, massive stars that ionise the surrounding gas with their intense radiation. Because these […]

Engineers Design Printable Centimeter-long Origami Robot

MIT Builds Tiny Origami Robot

Engineers at MIT have developed a tiny robot that can swim, climb an incline, traverse rough terrain, and carry a load twice its weight while being controlled by external magnetic fields. At the recent International Conference on Robotics and Automation, MIT researchers presented a printable origami robot that folds itself up from a flat sheet […]

Helium-Shrouded Planets May Be Common around Other Stars in Our Galaxy

Spitzer Reveals Helium-Shrouded Planets May Be Common in Our Galaxy

Using data from NASA’s Spitzer Space Telescope, astronomers propose that helium atmospheres may be found on thousands of warm Neptune- and sub-Neptune-sized exoplanets in our galaxy. They wouldn’t float like balloons or give you the chance to talk in high, squeaky voices, but planets with helium skies may constitute an exotic planetary class in our […]

Hubble Detects Stratosphere on Distant Planet WASP-33b

Hubble Telescope Detects Stratosphere on Distant Planet

Using NASA’s Hubble Telescope, a team of researchers has detected a stratosphere on the planet WASP-33b. A stratosphere occurs when molecules in the atmosphere absorb ultraviolet and visible light from the star. This absorption warms the stratosphere and acts as a kind of sunscreen layer for the planet below. NASA’s Hubble Space Telescope has detected […]

Cryogenic Storage Ring Reproduces the Chemical Conditions of Space

First Experiment in the Cryogenic Storage Ring

Researchers at the Max Planck Institute for Nuclear Physics conducted initial experiments in the Cryogenic Storage Ring. The Cryogenic Storage Ring can reproduce the chemical conditions in space in the laboratory. It is now easier to investigate space chemistry on Earth as well. Researchers at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg […]

Controlling Surface Topography with Particle-Enhanced Soft Composites

MIT Researchers Produce Soft Material with Controllable Surface Textures

Using a material that is composed of two different polymers with different degrees of stiffness, researchers have developed a soft material with controllable surface textures that can be varied by squeezing. An MIT team has developed a way of making soft materials, using a 3-D printer, with surface textures that can then be modified at […]

PROTACs: A New Type of Drug That Can Target All Disease-Causing Proteins

New Type of Drug Can Target All Disease-Causing Proteins

A newly published study from Yale University details the discovery of a new type of drug, called Proteolysis Targeting Chimeras (PROTACs), which can target all disease-causing proteins. Current drugs block the actions of only about a quarter of known disease-causing proteins, but Yale University researchers have developed a technology capable of not just inhibiting, but […]

VLT/SPHERE Reveal a Star Giving Birth to a Butterfly-Like Planetary Nebula

Image of L2 Puppis and Its Surroundings

ESO’s Very Large Telescope reveals for the first time what appears to be an aging star in the early stages of forming a butterfly-like planetary nebula. These observations of the red giant star L2 Puppis, from the ZIMPOL mode of the newly installed SPHERE instrument, also clearly showed a close companion. The dying stages of […]

MIT Physicists Create Ultracold Molecules of 23Na40K

Scientists Create Ultracold Molecules

A team of physicists from MIT has successfully cooled molecules in a gas of sodium potassium (NaK) to a temperature of 500 nanokelvins, creating ultracold molecules. The air around us is a chaotic superhighway of molecules whizzing through space and constantly colliding with each other at speeds of hundreds of miles per hour. Such erratic […]

Study Projects How Climate Change Will Affect the Functions Birds in Ecosystems Worldwide

Climate Change Will Affect the Functions Performed by Birds

New research from Yale University projects how climate change will affect the functions performed by birds in ecosystems worldwide. As changing climate reshapes the geographic range of thousands of bird species in the coming decades, ecosystems across wide swaths of the planet may be compromised, a new study warns. Based on environmental projections for the […]

NGC 6503: A Lonely Galaxy “Lost in Space”

Hubble Views Lonely Galaxy NGC 6503

This newly released Hubble image shows galaxy NGC 6503, which is located at the edge of what astronomers call the Local Void. Most galaxies are clumped together in groups or clusters. A neighboring galaxy is never far away. But this galaxy, known as NGC 6503, has found itself in a lonely position, at the edge […]

Chandra Reveals Evidence of Multiple Eruptions from a Black Hole

Supermassive Black Hole at the Center of NGC 5813 Has Erupted Multiple Times

NASA’s Chandra X-ray Observatory reveals that a supermassive black hole at the center of a group of galaxies has erupted multiple times over a period lasting about 50 million years. Evidence for the eruptions can be found in the cavities, or bubbles, carved out of the hot gas that envelops the galaxies and glows in […]
