Researchers Find a Link between Poor Sleep, Memory Loss and Brain Deterioration

Poor Sleep in Old Age Prevents the Brain from Storing Memories

New research from UC Berkeley suggests that sleep disruption in the elderly, mediated by structural brain changes, represents a contributing factor to age-related cognitive decline. Berkeley — The connection between poor sleep, memory loss and brain deterioration as we grow older has been elusive. But for the first time, scientists at the University of California, […]

A Step Towards 2-D Devices, Hybrid Graphene/Hexagonal Boron Nitride

Graphene Hexagonal Boron Nitride

Researchers at Rice University have shown the ability to pattern a conductor (graphene) and insulator (hexagonal boron nitride) into a one-atom-thick hybrid of graphene and hexagonal boron nitride, an important step toward the creation of two-dimensional electronics. Rice University scientists have taken an important step toward the creation of two-dimensional electronics with a process to […]

Regular Aspirin Use Linked to Age-Related Macular Degeneration

Aspirin Use Increases the Risk of Age Related Eye Disease

A new study found that regular aspirin use is significantly associated with an increased incidence of neovascular AMD, a leading cause of blindness in older people. Researchers at the Center for Vision Research from the Westmead Millennium Institute for Medical Research (WMI), a close affiliate of the University of Sydney, have found that regular aspirin […]

Magnetized Outflows from Center of the Milky Way are Driven by Star-Formation Activity

A False Color Image of Our Milky Way

In a newly published study, a team of scientists from the Smithsonian Astrophysical Observatory suggest that the recently discovered twin lobes of gamma-ray emission protruding about 50,000 light-years above and below the plane of our Milky Way galaxy are driven by star-formation activity, not black-hole activity. Two years ago, CfA astronomers reported the discovery of […]

Hubble Views Open Cluster NGC 411

Open Cluster NGC 411

This composite image from NASA’s Hubble Space Telescope shows open cluster NGC 411, which is located in the Small Magellanic Cloud. Globular clusters are roughly spherical collections of extremely old stars, and around 150 of them are scattered around our galaxy. Hubble is one of the best telescopes for studying these, as its extremely high […]

Research Shows Frequent Multitaskers Overrate Their Ability

Multitaskers Are Bad at It

New research from the University of Utah shows that the people most likely to multitask have the lowest multitasking ability, including people who talk on cell phones while driving. Most people believe they can multitask effectively, but a University of Utah study indicates that people who multitask the most – including talking on a cell […]

New Insights into How Retrograde Planets May Form and Endure

An Artists Rendition of the HAT P 7 System

Astronomers continue to research the HAT-P-7 planetary system, looking for new insights into how retrograde planets may form and endure. Astronomers have used the Subaru Telescope to show that the HAT-P-7 planetary system, which is about 1040 light years from Earth in the constellation Cygnus, includes at least two giant planets and one companion star […]

Study Shows that Dung Beetles Use Stars for Orientation

Dung Beetles Use Stars For Orientation

Researchers at Wits University demonstrated the use of the starry sky for orientation in dung beetles and provided the first documented use of the Milky Way for orientation in the animal kingdom. An insect with a tiny brain and minimal computing power has become the first animal proven to use the Milky Way for orientation. […]

Switching Behavior of Pulsar Challenges Emission Theories

A Pulsar That is Able to Dramatically Change the Way in Which it Shines

Astrophysicists at the University of Vermont have identified a pulsar that is able to quiet its radio waves while at the same time making its X-ray emissions much brighter, dramatically changing the way it shines. Pulsars — tiny spinning stars, heavier than the sun and smaller than a city — have puzzled scientists since they […]

Red Novae Help Explain the Secret Life of Binary Stars

Hubble Space Telescope Images Show an Expanding Burst of Light from a Red Supergiant Star

A newly published study from the University of Alberta examines what happens when binary stars come together in a common envelope, provides a way to identify common envelope events (CEEs) and explains the luminosity generated during the common envelope event. (Edmonton) A University of Alberta professor has revealed the workings of a celestial event involving […]

Seasonal Thawing Transforms Mars Surface

A Series of False Color Pictures of Sand Dunes in the North Polar Region of Mars

A new video from NASA’s Mars Reconnaissance Orbiter shows the springtime thaw of seasonal carbon dioxide ice on Mars that allows dust and gas to escape and reshapes the surface of the dunes. Pasadena, California — Researchers using NASA’s Mars Reconnaissance Orbiter see seasonal changes on far-northern Martian sand dunes caused by warming of a […]

Personal Experience of Climate Change May Influence Opinion of It

Perceiving Climate Change

A study from scientists at Yale University examined the extent to which 91,000 individuals in 89 countries on five continents detected recent changes in average local temperatures, finding that public opinion of climate change may shift in response to the personal experience of climate change. Human beings around the world are observing and accurately detecting […]

First USA Alzheimer’s Patient Implanted with Brain Pacemaker

The First Brain Pacemaker To Treat Alzheimer's

A new study that involves implanting a pacemaker in the brain is underway to determine if deep brain stimulation (DBS), the same technology used to successfully treat about 100,000 patients worldwide with movement disorders, can be used to treat Alzheimer’s patients. Columbus, Ohio – During a five-hour surgery last October at The Ohio State University […]

Discovery of ‘Bird-Dinosaur’ Eosinopteryx Challenges Bird Evolution Theory

Eosinopteryx

Findings related to the newly discovered ‘bird-dinosaur’ Eosinopteryx suggest that the origin of flight was much more complex than previously thought. The discovery of a new bird-like dinosaur from the Jurassic period challenges widely accepted theories on the origin of flight. Co-authored by Dr Gareth Dyke, Senior Lecturer in Vertebrate Palaeontology at the University of […]

Mathematical Model May Explain What Dark Matter Consists Of

A Revolutionary Theory of Dark Matter

University of Oslo’s leading theorist in astroparticle physics, Are Raklev, has launched a model that explains what dark matter may consist of and how one can discover the invisible particles experimentally. Astrophysicists have known for the last 80 years that most of the universe consists of an unknown, dark matter. The solution to the mystery […]
