New Vaccine Halves Malaria Risk

Med-trump Partial study results (147 comments)

There are couple of issues with the paper. 1. effect on young patients have not been analyzed. 2. The participants received exceptional medical care and therefore there was no difference between control and experimental group in terms of mortality. 3. Protection is partial unlike other vaccines. 4. It is not clear why did they publish the partial results. The associated editorial in the issue by Nicholas J. White is thought-provoking.

Can Long Term Research Survive the Coming Age of Austerity?

Med-trump Funding the elite (306 comments)

Funding the most elite is a dangerous idea. How would you determine who, the elite is? Most of the time being elite, means having the clout and running factory-like labs. Money should be distributed across and you will never know where the gem is! The US still has money for research, let's be optimistic. The best discoveries come in toughest of times!

Red Wine Counters Some Negative Health Effects of Microgravity

Med-trump Red Wine and Resveratrol (78 comments)

The contribution of resveratrol to the apparent beneficial effect of red wine is likely to be small. Red contains a ton of antioxidants and resveratrol is only one of them. In addition, the pharmacological dose administered to the animals is several hundred fold more than what we consume in red wine. Resveratrol is rapidly metabolized and therefore there is no additive effect either. It is strange that despite a large volume of literature on the potential of resveratrol in treating several diseases, human trails have been few!

Homicide is infectious

Med-trump Med-trump writes  |  about 2 years ago

Med-trump (2195662) writes ""We think of individuals who commit homicide as being unlike the rest of us," said April Zeoli, a public health researcher at Michigan State University's School of Criminal Justice. "We looked at homicide as an infectious disease," Zeoli said in an interview with NPR. "To spread, an infectious disease needs three things: a source of the infection; a mode of transmission; and we need a susceptible population." The researchers studied every homicide that occurred in the city of Newark, N.J., over a period of a quarter century, from January 1982 to September 2007. Zeoli said that the model could make specific predictions about how and where homicide would spread in the future — information that could prove very valuable to police and other city officials, according to NPR"

Why salamander genome is huger than that of the humans?

Med-trump Med-trump writes  |  about 2 years ago

Med-trump (2195662) writes "Whereas the human genome is made up of about 3.2 billion base pairs, a salamander genome may contain as many as 120 billion base pairs. The news article says that organisms shed their DNA over long evolutionary timescales, but salamanders did not. This interesting study was published in the journal Genome Biology and Evolution."

Scientists Produce the Lightest Material in the World

Med-trump Med-trump writes  |  more than 2 years ago

Med-trump (2195662) writes "A network of porous carbon tubes that is three-dimensionally interwoven at nano and micro level – this is the lightest material in the world and was produced by scientists from Northern Germany. It weights only 0.2 milligrams per cubic centimetre, and is therefore 75 times lighter than Styrofoam, but it is very strong nevertheless. The scientific results were published this month in the journal Advanced Materials."

Brains of anxious girls work harder

Med-trump Med-trump writes  |  more than 2 years ago

Med-trump (2195662) writes "In a paper published in the journal Psychophysiology, Michigan State University scientists say the brains of anxious girls work much harder than those of boys. The finding stems from an experiment in which college students performed a relatively simple task while their brain activity was measured by an electrode cap. Only girls who identified themselves as particularly anxious or big worriers recorded high brain activity when they made mistakes during the task."

Genome of Controversial Arsenic Bacterium Sequence

Med-trump Med-trump writes  |  about 3 years ago

Med-trump (2195662) writes "One year ago a media controversy was ignited when Felisa Wolfe-Simon and her colleagues held a press conference to announce the discovery of a bacterium that not only survived high levels of arsenic in its environment but also seemed to use that element in its DNA. Last week, the genome of the bacterium, known as GFAJ-1, which gets its name from the acronym for "Give Felisa a Job." (No joke!), was posted in Genbank, the public repository of DNA sequences for all who care to take a look. But it doesn't settle the debate over whether arsenic is used in DNA."

Walk-Through-Wall Effect Possible?

Med-trump Med-trump writes  |  about 3 years ago

Med-trump (2195662) writes "You can't walk through a wall. But this is possible for subatomic particles by a process called quantum tunneling. Now, a team of physicists says that it might just be possible to observe such tunneling with a larger, humanmade object, though others say the proposal faces major challenges. The research, conducted by scientists in Finland was publised this month in Physical Review B (Abstract)."

Alzheimer's Disease Without Amyloid Plaques

Med-trump Med-trump writes  |  more than 3 years ago

Med-trump (2195662) writes "Amyloid plaques have long been thought to be the cause of neuron loss in Alzheimer’s disease. Now researchers report that excess of mutated amyloid precursor protein (APP) inside the neurons is sufficient to induce neuron death. The report challenges the notion that amyloid deposits outside of the cells are necessary for neuron death in Alzheimer’s disease. The research was published in a recent issue of The Journal of Neuroscience."

Tevatron has come to the end of its run

Med-trump Med-trump writes  |  more than 3 years ago

Med-trump (2195662) writes "The US government's Chicago-area Fermilab has been at the forefront of high-energy physics. That's in large part thanks to the Tevatron, the machine that first reached the energies needed to discover the last quark in the Standard Model. But the Tevatron has come to the end of its run; at 2pm on Friday, it will be shut down for the last time."

Fatherhood Decreases Testosterone

Med-trump Med-trump writes  |  more than 3 years ago

Med-trump (2195662) writes "A new study shows that becoming a father leads to a sharp decline in testosterone, suggesting that although high levels of the hormone may help men win a mate, testosterone-fueled traits such as aggression and competition are less useful when it comes to raising children. The study published in the Proceedings of the National Academy of Sciences revealed that testosterone levels were lowest in men who reported spending the greatest amount of time spent caring for their children."

Joining blood vessels without sutures

Med-trump Med-trump writes  |  more than 3 years ago

Med-trump (2195662) writes "Stanford microsurgeons used a poloxamer gel and bioadhesive rather than a needle and thread to join together blood vessels. The technique published in the recent issue of Nature Medicine may replace the 100 year old method of reconnecting severed blood vessels with sutures. According to the authors of the study, "ultimately, this has the potential to improve patient care by decreasing amputations, strokes and heart attacks while reducing health-care costs.""

Transparent lithium-ion battery

Med-trump Med-trump writes  |  more than 3 years ago

Med-trump (2195662) writes "Stanford researchers say they have developed a transparent battery. Trasparent futuristic gadgets have been a topic of science fiction and dream of engineers. The paper "Transparent lithium-ion batteries" was published in the July 25 edition of the journal Proceedings of the National Academy of Sciences. They used a grid-structured electrode, which is fabricated by a microfluidics-assisted method, such that the feature dimension in the electrode is below the resolution limit of human eyes, and, thus, the electrode appears transparent."

Glucose meters find new uses

Med-trump Med-trump writes  |  more than 3 years ago

Med-trump (2195662) writes "Glucose meters are currently used to measure blood glucose levels. This gadget is a life-saving device for many diabetic patients as this can be used at home, office or on the road to test blood glucose level. A new study published in Nature Chemistry demonstrates its potential use in a multitude of other scenarios. Using molecular sensors called aptamers the authors demonstrate that this device can used for the quantitative detection of a broad range of target molecules in blood, water or food. According to the authors "The advantages of our method are high portability, low cost, wide availability and quantitative detection of a broad range of targets in medical diagnostics and environmental monitoring.""

New Genetic Map From African-Americans

Med-trump Med-trump writes  |  more than 3 years ago

Med-trump (2195662) writes "New genetic maps have been created using DNA from African-Americans. Presently available maps are derived using DNA information from caucasians. "There's a family of about 2,500 hot spots of recombination that are active in people of West African ancestry, like African-Americans, which are almost completely inactive in people of non-African ancestry," Reich, one of the authors of the study, says. As Africa is thought to be the place where all modern humans originally came from, the map will provide useful information about not only African-Americans but also the genetics of humans in general. The papers were published in the recent issues of Nature and Nature genetics"

Neanderthals mated with human

Med-trump Med-trump writes  |  more than 3 years ago

Med-trump (2195662) writes "Neanderthals, whose ancestors left Africa about 400,000 to 800,000 years ago, evolved in what is now mainly France, Spain, Germany and Russia, and are thought to have lived until about 30,000 years ago. Now scientists have identified a piece of Neanderthal DNA (called a haplotype) in the human X chromosome and conclude that this haplotype is present because of mating with our ancestors and Neanderthals. The study was published in the latest issue of the journal Molecular Biology and Evolution."
