Current research from scientists at Louisiana State University published in the February 2008 print issue of Archives of Neurology (one of the JAMA/Archives journals) has shown that combining a traditionally used medication against multiple sclerosis with an antibiotic may prove to slow the progress of the disease.
Defying current beliefs about the spinal cord, a UCLA study has shown that the central nervous system is capable of reorganizing signaling pathways in response to spinal cord damage. The discovery, published in the January 2008 issue of Nature Medicine, could lead to new approaches in the way researchers and clinicians seek to restore mobility following spinal cord injury.
Japanese whaling will resume with double the number of whales killed for self-proclaimed scientific research, reports Reuters in a December 19 press report. The Australian Centre for Applied Marine Mammal Science has responded with a campaign to count the number of Antarctic minke whales by flying over 58,000 square miles of pack ice off eastern Antarctica. The Australian researchers say the count will be the first accurate one since the 1980s.
The typical home user today connects to the Internet through copper cable phone or cable lines. Through these lines, the user has gained access to an unprecedented amount of information. However, as more high-quality material become available online, these lines now pose a speed limit, at up to ten megabits per second (Mbps), for the typical user. Fiber optics, on the other hand, can potentially bring this limit into the gigabits per second (Gbps).
A cocaine vaccine developed by the U.K. pharmaceutical company Xenova eliminates the "high" addicts feel by activating the immune system to attack cocaine molecules. A press report released by the Associated Press on January 1, 2008 explains the study, which is lead by psychiatric professor Dr. Tom Kosten and his wife Therese, a psychologist and neuroscientist, both researchers at Baylor College of Medicine in Houston.
Can hearts, or any other organ, be grown in a lab? Apparently researchers at the University of Minnesota Center for Cardiovascular Repair think so.
In research published in the January issue of Cell Metabolism, researchers found evidence that exercise could induce stem cells known as satellite cells to buff up muscles. These scientists from the Program on Differentiation and Cancer, Center for Genomic Regulation (CRG) and Center for Neurodegenerative Diseases (CIBERNED), Pompeu Fabra University, Barcelona, Spain suggest that exercise could have a more profound effect on your muscles than you think.
A recent study conducted by Imperial College London details for the first time a host of biochemical effects facilitated by probiotics, or dietary supplements made with live bacteria. The findings, published in a January issue of Molecular Systems Biology, suggest that yogurt drinks such as Dannon's Activia may alter metabolic trends and help with digestion.
The evolution of C4 plants which include maize, sugar cane, and other biofuels - has been of great ecological and agricultural importance. However, the origin of C4 plants from C3 plants, has only been a speculation until now.
It's an audiophile's worst nightmare: scoring impossible-to-get tickets to the best concert of the year, and having to sit directly behind a giant pillar of rock! If this though has ever frightened you, then worry no more!
In approximately 20 to 40 million years, Smith's cloud, a giant cloud composed of hydrogen gas will slam into the Milky Way galaxy, resulting in the formation of as many as a million new stars, a study from the National Radio Astronomy Observatory (NRAO) has found. The explosion from the collision will cause a spectacular firework-like display within the local group, a group comprised of 30 galaxies, including our own galaxy the Milky Way.
The coldest form of matter ever created just got a little more interesting. In the February 2007 issue of Nature, researchers at Harvard University reported storing a light pulse in an ultra-cold cloud of atoms (known as a Bose-Einstein condensate, or BEC) and then retrieving it from another BEC some distance away. This showed that light can essentially "jump" from one place to another. According to lead author Lene Hau, professor of physics at Harvard University, "by manipulating the matter copy [of the original light pulse], we can process optical information." This finding may have potential applications in developing the next generation of computers known as quantum' computers.
The days of using overloaded and possibly hazardous electrical sockets for the purposes of powering and recharging appliances and gadgets might soon be a thing of the past. In the July 6th edition of the journal Science, researchers at MIT announced the success of an efficient power transfer between two coils over a large distance relative to their size. Presently, things such as security swipe cards can transmit electricity via magnetic induction but can only do so over a small distance.
The domestic dog is an animal that is special in many ways. It is an animal that has been artificially selected by humans for thousands of years and has taken on a variety of roles in human societies from being companions to circus animals to guards and guides. Despite the intimacy with human beings, we all know of instances in which there have been rough and sometimes violent encounters between people and these canine creations.
To study the Earth is to study the present in order to make inferences about the past and predictions for the future. The understanding of geology is more than just to provide scientific background for major blockbuster disaster movies like "Volcano" or "The Core" (not that either of these films can boast any sort of satisfactory basis on science), but to help the general public prepare for potential natural disasters as well as attempt to mitigate the effects that might trigger them.
I heard a story once, of a young boy named Norbert who visited the La Brea Tar Pits, located in Los Angeles, California. One of the many displays they have at the museum is that of a Woolly Mammoth's skeleton. As Norbert stared at this creature amazingly recreated before him, he asked the curator, "How did modern elephants emerge through evolution from the Woolly Mammoth?
The African elephants (Loxodonta africana), Asian elephants (Elephas maximus) and Woolly Mammoths (Mammuthus primigenius) diverged approximately 4-6 million years ago. The exact relationship amongst them has always remained controversial. Morphological studies have suggested a Mammuthus-Elephas clade while several others have supported Loxodonta-Mammuthus clade. Recently, phylogenetic trees based on mitochondrial DNA (mtDNA) and nuclear DNA sequences of respective elephants, also refuted each other. This has left the phylogenetic relationship between these elephants, unresolved.
The domestic dog is a ubiquitous species having frequent encounters with humans; in the U.S. over 4 million of these result in a dog bite. These injuries might be reduced by improving human-canine communication. Canine responses to alterations of human facial expressions were recorded. The dogs' responses to the presence of a human experimenter were subsequently analyzed against survey data collected by the shelter on the individual animals (time in shelter, age, sex, reason surrendered). Staring at a dog induced more arousal than other human facial expressions (i.e., Averting Eyes, Grinning, or Yawning).
