Water World

Following the paths of radicals and finding many damaged residues because of incredibly accurate, fast and sensitive mass spectrometry, three Washington University scientists studied the great granddaddy of all photosynthetic organisms -- a strain of cyanobacteria -- to develop the first experimental map of that organism's water world.

Observatory in Mexico Sheds Light on Origin of Excess Positrons in Outer Space

Using new data from the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory in Mexico, researchers have ruled out two pulsars previously believed to be the source of excess positrons just above the Earth's atmosphere.

On the Origins of Star Stuff: HAWC Collaboration Sheds Light on Origin of Anti-Matter

Michigan Tech team and others use a high-altitude observatory in Mexico to better understand where gamma rays come from.

New Deposition Technique Puts the Heat on Silicon

Research offers cost-effective development of germanium, more efficient semiconductor than silicon

Vanderbilt Astronomers Continue International Effort to Map and Analyze Universe in Greater Detail Than Ever

Vanderbilt astronomers will join the 5th generation of the Sloan Digital Sky Survey to study nearby solar systems with the potential to harbor life

Cyanobacterial Studies Examine Cellular Structure During Nitrogen Starvation

Researchers from Washington University in St. Louis and ORNL are using neutrons to study what happens when cyanobacteria cell samples are starved for nitrogen. They are especially interested in how this process affects phycobilisomes, large antenna protein complexes in the cells that harvest light for photosynthesis.

With Launch of New Night Sky Survey, UW Researchers Ready for Era of 'Big Data' Astronomy

On Nov. 14, scientists with the California Institute of Technology, the University of Washington and eight additional partner institutions announced that the Zwicky Transient Facility, the latest sensitive tool for astrophysical observations in the Northern Hemisphere, has seen "first light" and took its first detailed image of the night sky.

Fuertes Observatory Celebrates a Century of Scanning the Cosmos

Fiery supernovae, delicate rings of ice, planet-hopping comets - visitors to Fuertes Observatory have seen them all. For 100 years, Fuertes Observatory has opened a window to the cosmos for the Cornell and Ithaca communities.

SLAC's Helen Quinn Honored with 2018 Benjamin Franklin Medal in Physics

Helen Quinn, a professor emerita at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University, will receive the 2018 Benjamin Franklin Medal in Physics - one of eight prestigious Franklin Institute Awards that will be handed out in Philadelphia next April.

PPPL Honors Grierson and Greenough for Distinguished Research and Engineering Achievements

Article describes PPPL's presentation of 2017 Kaul Prize and Distinguished Engineering Fellow awards.

Duo of Titanic Galaxies Captured in Extreme Starbursting Merger

New observations with ALMA have uncovered the never-before-seen close encounter between two astoundingly bright and spectacularly massive galaxies in the early universe.

NASA's James Webb Space Telescope Early Science Observations Revealed

Astronomers around the world will have immediate access to early data from specific science observations from NASA's James Webb Space Telescope, which will be completed within the first five months of Webb's science operations. These observing programs were chosen from a Space Telescope Science Institute call for early release science proposals.

Johns Hopkins APL and FS-ISAC Operationalize the Integrated Adaptive Cyber Defense Framework to Improve Cybersecurity in Critical Sectors

The Johns Hopkins Applied Physics Laboratory and the Financial Services Information Sharing and Analysis Center are operationalizing the Integrated Adaptive Cyber Defense (IACD) framework, which will enable companies to improve the ability to quickly and broadly share information and prevent and respond to cyberattacks.

Plasma From Lasers Can Shed Light on Cosmic Rays, Solar Eruptions

A team of researchers led by PPPL physicist Will Fox recently used lasers to create conditions that mimic astrophysical behavior. The laboratory technique enables the study of outer-space-like plasma in a controlled and reproducible environment.

JHU Scientist Crowdsources Rocks Harboring Earthly "Extraterrestrials"

Crowdsourcing created an online photography archive, financed a British rock band's tour and advanced a search for intelligent life on other planets. Now a biologist is hoping the approach can help her find rocks. But not just any rocks.

Hermann Grunder Recognized by IEEE Nuclear and Plasma Sciences Society

Dr. Hermann Grunder, Founding Director of Jefferson Lab, has been selected as one of two recipients of the 2018 IEEE NPSS Particle Accelerator Science and Technology (PAST) Award.

Live Webcast to Explore the Ways "Useless" Discoveries Have Changed Our Lives

.In a live webcast on November 8, physicist Pauline Gagnon will explain how seemingly "useless" scientific discoveries, such as the Higgs boson, have changed the way we live our lives.

New Study: Scientists Narrow Down the Search for Dark Photons Using Decade-Old Particle Collider Data

A fresh analysis of particle-collider data, co-led by Berkeley Lab physicists, limits some of the hiding places for one type of theorized particle - the dark photon, also known as the heavy photon - that was proposed to help explain the mystery of dark matter.

Closing the Rural Health Gap: Media Update from RWJF and Partners on Rural Health Disparities

Rural counties continue to rank lowest among counties across the U.S., in terms of health outcomes. A group of national organizations including the Robert Wood Johnson Foundation and the National 4-H Council are leading the way to close the rural health gap.

Scientists See Fireworks From Atoms at Ultra-Low Temperatures

Scientists aren't normally treated to fireworks when they discover something about the universe. But a team of University of Chicago researchers found a show waiting for them at the atomic level--along with a new form of quantum behavior that may someday be useful in quantum technology applications.

A giant collision of several galaxy clusters, each containing hundreds of galaxies, has produced this spectacular panorama of shocks and energy.

Researchers Model Coulomb Crystals to Understand Star Evolution

Matter in the cores of old white dwarfs and the crusts of neutron stars is compressed to unimaginable densities by intense gravitational forces. The scientific community believes this matter is composed of Coulomb crystals that form at temperatures potentially as high as 100 million Kelvin. Researchers in Russia clarify the physics of these crystals this week in the journal Physics of Plasmas.

Where Did Those Electrons Go? X-Ray Measurements Solve Decades-Old Mystery

There's been an unsolved mystery associated with mixed valence compounds: When the valence state of an element in these compounds changes with increased temperature, the number of electrons associated with that element decreases, as well. But just where do those electrons go? Using a combination of state-of-the-art tools, including X-ray measurements at the Cornell High Energy Synchrotron Source (CHESS), a group of researchers at Cornell University have come up with the answer.
