Researchers at the University of Southampton have taken a significant step in a project to unravel the secrets of the structure of our Universe.
Professor Kostas Skenderis, Chair in Mathematical Physics at the University, comments: "One of the main recent advances in theoretical physics is the holographic principle. According to this idea, our Universe may be thought of as a hologram and we would like to understand how to formulate the laws of physics for such a holographic Universe."
Astronomers using NASA's Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, yielding clues they can use to understand these extremely dense objects.
A neutron star is the crushed core of a massive star that ran out of fuel, collapsed under its own weight, and exploded as a supernova. A neutron star can spin as fast as 43,000 times per minute and boast a magnetic field a trillion times stronger than Earth's. Matter within a neutron star is so dense a teaspoonful would weigh about a billion tons on Earth.
Millions of people with type 1 diabetes depend on daily insulin injections to survive. They would die without the shots because their immune system attacks the very insulin-producing cells it was designed to protect. Now, a University of Missouri scientist has discovered that this attack causes more damage than scientists realized. The revelation is leading to a potential cure that combines adult stem cells with a promising new drug.
CORVALLIS, Ore. – Researchers at Oregon State University have helped develop new environmental monitoring technology that will allow farmers thousands of miles away, in west and central Asia, to save millions of dollars while more effectively combatting a pest that is threatening their wheat crops.
The way in which stars evolve and end their lives was for many years considered to be well understood. Detailed computer models predicted that stars of a similar mass to the Sun would have a period towards the ends of their lives -- called the asymptotic giant branch, or AGB [1] -- when they undergo a final burst of nuclear burning and puff off a lot of their mass in the form of gas and dust.
The physics behind some of the most extraordinary stellar objects in the Universe just became even more puzzling.
A group of astronomers led by McGill researchers using NASA's Swift satellite have discovered a new kind of glitch in the cosmos, specifically in the rotation of a neutron star.
Astrophysicists have found that contrary to decades of orthodoxy, stars with a high sodium content die before reaching the final, spectacular stages of life.
In a study published today in Nature, an international group of researchers led by Dr Simon Campbell of the Monash Centre for Astrophysics (MoCA), used the European Southern Observatory's 'Very Large Telescope' (VLT) to observe NGC 6752, a globular cluster of stars in our galaxy, 13,000 light years from Earth.
University Park, PA -- One of the densest objects in the universe, a neutron star about 10,000 light years from Earth, has been discovered suddenly putting the brakes on its spinning speed. The event is a mystery that holds important clues for understanding how matter reacts when it is squeezed more tightly than the density of an atomic nucleus -- a state that no laboratory on Earth has achieved. The discovery, by an international team of scientists that includes a Penn State University astronomer, will be published in the journal Nature on 30 May 2013.
Researchers from Northeastern University are among the many scientists helping NASA use the weightlessness of space to design stronger materials here on Earth.
The snow is mostly gone in Siberia which means that the time is ripe for wildfires. This region is mostly dry when the snows are gone and lightning or a carelessly thrown cigarette can easily start a wildfire. This natural-color satellite image was collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite on May 29, 2013. Actively burning areas, detected by MODIS's thermal bands, are outlined in red.
Women who have mental health disorders around the time of birth are more likely to have previously experienced domestic violence, according to a study by UK researchers published in this week's PLOS Medicine.
The researchers, led by Louise Howard from King's College London, found that high levels of symptoms of perinatal* depression, anxiety, and post-traumatic stress disorder were linked to having experienced domestic violence either during pregnancy, the past year, or over a woman's lifetime.
NASA's Aqua satellite captured an image of System 92E, a tropical low pressure area that is ripe for development into a tropical depression and tropical storm, as it continues to develop near to southwestern Mexico.
Hikers in New Hampshire's White Mountain National Forest often hit the trail less prepared than they should be, according to a paper that gaged readiness by how many of 10 essential items the hikers brought along.
Young and inexperienced hikers were most likely to lack multiple items recommended by the State of New Hampshire's HikeSafe program, according to a paper in press at the journal Wilderness & Environmental Medicine. Hikers were also less likely to prepare fully if they were planning a short hike, even though those can quickly become dangerous.
An integrated system of stroke care delivery in Ontario, Canada, has resulted in fewer deaths from stroke and fewer discharges to long-term care facilities because of better access to optimal stroke care, according to a study published in CMAJ (Canadian Medical Association Journal).
May 24, 2013 –A frequently expressed concern in the ongoing public health debate is the lack of affordability of fresh vegetables, especially those that are nutrient dense.
