Investigators from Ludwig-Maximilians-Universität München and a Bolzano colleague have written another chapter in a murder case over 5,000 years old. New investigations reconstructed the chronology of the injuries that
Oetzi, the glacier man preserved as a frozen mummy, received in his last days.
In 2007 chocolate was all the rage,
with Mars, Inc.-funded scientists even having their own panel at the AAAS meeting. In 2008,
blueberries were the rage.
In 2009, says Dr. Luis Cisneros, Texas A&M AgriLife Research food scientist, "Stone fruits are super fruits, with plums as emerging stars."
Astronomers have observed the intense heating of a distant planet as it swung close to its parent star, providing important clues to the atmospheric properties of the planet. With that data, astronomers at the University of California, Santa Cruz were able to generate 'realistic' images of the planet by feeding the data into computer simulations of the planet's atmosphere. The researchers used NASA's Spitzer Space Telescope to obtain infrared measurements of the heat emanating from the planet as it whipped behind and close to its star. In just six hours, the planet's temperature rose from 800 to 1,500 Kelvin (980 to 2,240 degrees Fahrenheit).
An international team of researchers has uncovered the first gene linked to the most common type of epilepsy, called Rolandic epilepsy. One out of every five children with epilepsy is diagnosed with this form, which is associated with seizures starting in one part of the brain.
The finding is the first step in unlocking the causes of common childhood epilepsies and developing more effective treatments. Children with Rolandic and other types of epilepsies are usually treated with drugs that prevent seizures by suppressing electrical activity in the entire brain.
The team operating NASA's Mars Exploration Rover Spirit plans diagnostic tests this week after Spirit did not report some of its weekend activities, including a request to determine its orientation after an incomplete drive.
On Sunday, during the 1,800th Martian day, or sol, of what was initially planned as a 90-sol mission on Mars, information radioed from Spirit indicated the rover had received its driving commands for the day but had not moved. That can happen for many reasons, including the rover properly sensing that it is not ready to drive. However, other behavior on Sol 1800 was even more unusual: Spirit apparently did not record the day's main activities into the non-volatile memory, the part of its memory that persists even when power is off.
Recent studies have suggested that autism spectrum disorder (ASD) may be more prevalent among children born very prematurely. The early symptoms of ASD are also associated with other conditions related to preterm births, such as cerebral palsy, which can make it difficult to correctly screen children for ASD. Because of this, researchers have begun to explore the relationship between preterm birth, cognitive and developmental impairments, and ASD.
Two articles soon to be published in The Journal of Pediatrics explore this possible correlation between preterm birth and ASD.
Name it and the milk will come, say scientists at Newcastle University. It's not "Field of Dreams" it's Milk of Dreams. Or whatever analogy you want to use for a correlation-causation fantasy that leads to a conclusion that a cow with a name produces more milk than one without.
Drs Catherine Douglas and Peter Rowlinson say they have shown in their study in Anthrozoos ("A Multidisciplinary Journal of The Interactions of People and Animals"!!) that by giving a cow a name and treating her as an individual farmers can increase their annual milk yield - by over 60 gallons.
We get a spectacular new into the active galaxy Centaurus A - NGC 5128 - as the jets and lobes emanating from the central black hole have been imaged at submillimeter wavelengths for the first time.
Centaurus A is our nearest giant galaxy - about 13 million light-years away in the southern constellation of Centaurus. It is an elliptical galaxy, currently merging with a companion spiral galaxy, resulting in areas of intense star formation and making it one of the most spectacular objects in the sky. Centaurus A hosts a very active and highly luminous central region, caused by the presence of a supermassive black hole (see ESO 04/01), and is the source of strong radio and X-ray emission.
Taking up valuable land and growing edible crops for biofuels poses a dilemma: Is it ethical to produce inefficient renewable energies at the expense of an already malnourished population? David Pimentel and colleagues from Cornell University highlight the problems linked to converting a variety of crops into biofuels. Not only are these renewable energies inefficient, they are also economically and environmentally costly and nowhere near as productive as projected.
Rocks formed only under the extreme heat and friction during earthquakes, called pseudotachylytes, may be more abundant than previously reported, according to new research focused on eight faults found in the Sierra Nevada. The research appears in the February issue of the Bulletin of the Seismological Society of America.
Geologists have previously debated whether these rocks are rarely produced or not based on an apparent absence in the rock record, most likely brought about by the difficulty in identifying them. Only a small fraction of the energy released in an earthquake is consumed by seismic waves, the formation of pseudotachylytes reveals the importance of the heat generated by the earthquake process.
