Researchers Improve Spin Coherence Time of Nitrogen Vacancy Centers

Researchers Improve Spin Coherence Time of Nitrogen Vacancy Centers

In a new study, researchers demonstrate an improvement of more than two orders of magnitude in the spin coherence time of nitrogen-vacancy centers as compared with previous measurements. The findings could advance quantum sensing, enable squeezing and many-body entanglement, and open a path to simulating driven, interaction-dominated quantum many-body Hamiltonians. From brain to heart to […]

Protein Makes Old Hearts Younger, Reverses Some Effects of Aging

Protein GDF 11 Reverses Aging in the Heart

Researchers have identified a protein in the blood of mice and humans that may prove to be the first effective treatment for a form of age-related heart failure, finding in mice that hearts reduced in size and thickness and resembled healthy hearts of younger mice when the protein GDF-11 was injected. Two Harvard Stem Cell […]

Study Suggests Earth and Moon Have Common Water Source

Earth and Moon Have Common Water Source

Using a multicollector ion microprobe to study hydrogen-deuterium ratios in lunar rock and on Earth, a new study suggests that water on the Moon is leftover from when a giant collision sent a disc of debris from Earth to form the Moon, about 4.5 billion years ago. Providence, Rhode Island (Brown University) — Water inside […]

Project 1640 Reveals Precise Composition Information about Four HR 8799 Planets

 Project 1640 Rveals New Information about the Atmospheres of the Four Giant Red Planets

Using infrared cameras equipped with spectrographs at the Palomar Observatory in California, Project 1640 was able to get precise composition information about four planets around one overwhelmingly bright star, HR 8799. The data revealed that all four planets, though nearly the same in temperature, have different compositions. Gone are the days of being able to […]

Hubble Finds Planetary Debris Whirling Around Two White Dwarfs

Hubble Discovers Rocky Debris Around Two Hyades White Dwarfs

The Hubble Space Telescope has detected signs of Earth-like planets in debris whirling around two white dwarfs, finding silicon in the stars’ atmospheres and detecting low levels of carbon. The NASA/ESA Hubble Space Telescope has found signs of Earth-like planets in an unlikely place: the atmospheres of a pair of burnt-out stars in a nearby […]

Brainwave Activity Predicts How Well People Can Overcome Ingrained Biases

Theta Brainwave Activity Predicts How Well People Can Overcome Biases

A newly published study found that theta brainwave activity in the prefrontal cortex predicts how well people can overcome ingrained biases when better choices are available. The research could be applied to studying and treating conditions such as addiction or obsessive-compulsive disorder. Providence, Rhode Island — Vertebrates are predisposed to act to gain rewards and […]

Mechanism for Controlling Calcium Influx in Cells Identified

Mechanism for Controlling Calcium Influx in Cells Identified

In a newly published study, scientists identify the mechanism for controlling calcium influx in cells, helping researchers better understand the molecular causes of the disruption of brain functioning that occurs in stroke and other neurological disorders. When brain cells are overwhelmed by an influx of too many calcium molecules, they shut down the channels through […]

Astronomers Discover Hydrogen Clouds between Nearby Galaxies, Andromeda and Triangulum

Intergalactic Clouds Lurking Between Nearby Galaxies Andromeda and Triangulum

Using the National Science Foundation’s Green Bank Telescope, astronomers detected a never-before-seen cluster of hydrogen clouds strewn between two nearby galaxies, Andromeda (M31) and Triangulum (M33). In a dark, starless patch of intergalactic space, astronomers have discovered a never-before-seen cluster of hydrogen clouds strewn between two nearby galaxies, Andromeda (M31) and Triangulum (M33). The researchers […]

Thermal Cloak Molds the Flow of Heat Around an Object

Invisibility Cloak for Thermal Flow

Scientists from the Karlsruhe Institute of Technology have constructed a micro-structured thermal cloak that molds the flow of heat around an object. By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of […]

Study Suggests Europeans Are Closely Related

Geography of Recent Genetic Ancestry Across Europe

A newly published study suggests that Europeans are closely related, finding on a genealogical level that everyone in Europe traces back to nearly the same set of ancestors only a thousand years ago. From Ireland to the Balkans, Europeans are basically one big family, closely related to one another for the past thousand years, according […]

New Climate Model Suggests Boreal Forests to Shift North and Relinquish More Carbon Than Expected

As Climate Changes Boreal Forests to Shift North

New climate change research from the Berkeley Lab suggests that boreal forests will likely shift north and will relinquish more trapped carbon than most current climate models predict. It’s difficult to imagine how a degree or two of warming will affect a location. Will it rain less? What will happen to the area’s vegetation? New […]

Potential New Therapy Stops Tumor Growth

Monoclonal Antibody Therapy Stops Tumor Growth in Mice

Scientists have identified a way to flip a genetic switch off to halt tumor growth, demonstrating a potential new therapy in mice that impacts tumor growth in a significant way. Approximately 90 percent of cancers start within tissues that form the inner linings of various organs. Decades of accumulated genetic mutations can, on occasion, induce […]

Researchers Believe They Can Reliably Predict Snowstorms on Mars

Climate Model Helps Predict Snowstorms on Mars

Using a climate model adapted to the special conditions on Mars, researchers believe they can reliably predict snowstorms on Mars far in advance, helping future missions choose better routes that avoid heavy snowfall. Snowstorms lashing down at the northern hemisphere of Mars during the icy cold winters may be predicted several weeks in advance, say […]

Increased Parkin Gene Levels Can Delay the Aging Process

Boositng Parkin Gene Can Delay Aging

In a new study, UCLA researchers increased parkin levels in the cells of fruit flies, discovering that this extended their life span by more than 25 percent as compared with a control group that did not receive additional parkin. UCLA life scientists have identified a gene previously implicated in Parkinson’s disease that can delay the […]

New Metamaterial Doubles the Range of Light that Can Be Manipulated

Stanford Scientists Designing a Metamaterial that Doubles the Range of Light that Can Be Manipulated

By designing a broadband metamaterial that more than doubles the range of wavelengths of light that can be manipulated, Stanford scientists have taken an important step toward designing a metamaterial that works across the entire visible spectrum. All natural materials have a positive index of refraction – the degree to which they refract light. The […]

Scientists Reveal a New Species of Dinosaur

Scientists Reveal a New Species of Dinosaur

New research describes the newly discovered species of bone-headed dinosaur, named Acrotholus audeti, which lived about 85 million years ago. Scientists have named a new species of bone-headed dinosaur (pachycephalosaur) from Alberta, Canada. Acrotholus audeti (Ack-RHO-tho-LUS) was identified from both recently discovered and historically collected fossils. Approximately six feet long and weighing about 40 kgs […]
