Berkeley Physicists Demonstrate That Space is Not Squeezed

Quantum Computer Shows Space Is Not Squeezed

Using partially entangled atoms, a new experiment by UC Berkeley physicists demonstrated more precisely than ever before that space looks the same in all directions. Berkeley — Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions […]

Transforming Mini-Neptunes into Habitable Super-Earths

Transforming Mini-Neptunes into Super-Earths

A new study from the University of Washington details how strong irradiation from the host star can cause planets known as mini-Neptunes in the habitable zone to shed their gaseous envelopes and become potentially habitable worlds. Two phenomena known to inhibit the potential habitability of planets — tidal forces and vigorous stellar activity — might […]

How Cancer Uses Notch Signaling to Promote Metastasis

How Cancer Turns Good Cells Bad

A new computational study shows how cancer cells take advantage of the system by which cells communicate with their neighbors as they pass messages to “be like me” or “be not like me.” Cancer uses a little-understood element of cell signaling to hijack the communication process and spread, according to Rice University researchers. Led by […]

Yale Research Shows Immune Cells Are an Ally, Not Enemy, in Battle Against Alzheimer’s

Study Shows Immune Cells Are An Ally Against Alzheimer’s

New research in battle against Alzheimer’s shows that brain immune cells (called microglia) seem to protect the brain by keeping amyloid plaques corralled, and are not re responsible for inflammation and damage to surrounding brain cells as previously thought. Beta-amyloid is a sticky protein that aggregates and forms small plaques in the brains of the […]

Titan Exposed to the Full Force of the Solar Wind

Cassini Views Titan Fully Exposed to Solar Wind

NASA’s Cassini spacecraft has observed Titan in the supersonic and super-Alfvénic solar wind, revealing that Titan’s interaction with the solar wind is in many ways similar to unmagnetized planets Mars and Venus and active comets in spite of the differences in the properties of the solar plasma in the outer solar system. Titan is large […]

Hubble Telescope Views Spiral Galaxy NGC 7714

Hubble Views Spiral Galaxy NGC 7714

This newly released Hubble image shows spiral galaxy NGC 7714, which is located 100 million light-years from Earth. This NASA Hubble Space Telescope photo of NGC 7714 presents an especially striking view of the galaxy’s smoke-ring-like structure. The golden loop is made of sun-like stars that have been pulled deep into space, far from the […]

New VLT Image of Cometary Globule CG4

Cometary Globule CG4

This newly released image from ESO’s Very Large Telescope shows cometary globule CG4, which is located about 1300 light-years from Earth. Like the gaping mouth of a gigantic celestial creature, the cometary globule CG4 glows menacingly in this new image from ESO’s Very Large Telescope. Although it appears to be big and bright in this […]

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

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 Vitamin D Protects Against Colorectal Cancer

Vitamin D Protects Against Colorectal Cancer

A newly published study from the Dana-Farber Cancer Institute reveals that vitamin D can protect some people with colorectal cancer by perking up the immune system’s vigilance against tumor cells. The research, published by the journal Gut, represents the first time that a link between vitamin D and the immune response to cancer has been […]

A New Way to Detect the Early Stages of Massive Star Formation

Citizen Scientists Find Mystery Objects in Space

Using data from NASA’s Spitzer Space Telescope, volunteers discovered a new way to detect the early stages of massive star formation. Sometimes it takes a village to find new and unusual objects in space. Volunteers scanning tens of thousands of starry images from NASA’s Spitzer Space Telescope, using the Web-based Milky Way Project, recently stumbled […]

HESS Discovers New Gamma Ray Sources in Large Magellanic Cloud

New Gamma Ray Sources Discovered in Large Magellanic Cloud

The H.E.S.S. telescope system has discovered three extremely luminous gamma-ray sources in the Large Magellanic Cloud. Once again, the gamma ray observatory H.E.S.S. has demonstrated its detecting capabilities: in the Large Magellanic Cloud, the High Energy Stereoscopic System discovered most luminous high-energy gamma-ray sources. These are three objects of different type: a powerful pulsar wind […]

Ring System Around J1407b is Roughly 200 Times Larger Than Saturn’s Rings

Gigantic Ring System Larger Than Saturn’s

A new study from astronomers at the Leiden Observatory reveals details about the gigantic ring system around J1407b. Astronomers at the Leiden Observatory, The Netherlands, and the University of Rochester, USA, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier […]

New Experiments and Simulations Help Explain Collagen’s Force

New Analysis Explains Collagen’s Force

New research from MIT shows that adding or removing small amounts of water from collagen in tendons can generate surprisingly strong forces, as much as 300 times stronger than the forces generated by muscles. Research combining experimental work and detailed molecular simulations has revealed, for the first time, the complex role that water plays in […]

Kepler-444: An Ancient Extrasolar System with Five Sub-Earth-Size Planets

Astronomers Discover an Ancient Extrasolar System with Five Sub-Earth-Size Planets

Using data from the Kepler spacecraft, astronomers have discovered a compact system of five transiting planets with sizes between those of Mercury and Venus. They validate this system as a true five-planet system orbiting the target star and provide a detailed characterization of its planetary and orbital parameters based on an analysis of the transit […]

Dawn Spacecraft Captures Best-Ever View of Ceres

Best Ever View of Ceres

The sharpest images ever seen of the dwarf planet Ceres were taken by NASA’s Dawn spacecraft on January 25. The images were taken 147,000 miles (237,000 kilometers) from Ceres and represent a new milestone for a spacecraft that soon will become the first human-made probe to visit a dwarf planet. “We know so little about […]

Asteroid 2004 BL86 Has a Small Moon

Asteroid 2004 BL86 and Its Small Moon

As asteroid 2004 BL86 made its way past Earth yesterday, scientists were able to better measure the asteroid’s size, rotation and location and detected a tiny moon orbiting the asteroid. This “movie” of the asteroid was generated from radar data collected on that date by NASA’s Deep Space Network antenna at Goldstone, California. Twenty individual […]

UC Researchers Make Magnetic Graphene

Magnetic Graphene

Physicists from the University of California – Riverside have found a way to induce magnetism in graphene while also preserving graphene’s electronic properties. Riverside, California – Graphene, a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice, has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in […]
