On June 7, 2011, our Sun erupted, blasting tons of hot plasma into space.
Some of that plasma splashed back down onto the Sun’s surface, sparking bright flashes of ultraviolet light. This dramatic event may provide new insights into how young stars grow by sucking up nearby gas.
The eruption...
A university study into the incubation behavior of modern birds is shedding new light on the type of parental care carried out by their long extinct ancestors.
The study, by researchers at George Mason University and University of Lincoln (United Kingdom), aimed to test the hypothesis that...
I graduate from college in a week as a double major with a BS in psychology and a BS in business. I have an average GPA of 3.7, paid experience in event planning, marketing, management, etc due to being a senior member on the student activities board. I also tutored both math and English, and...
Through a collaborative genome-wide study on individuals, researchers have discovered 14 new genetic variations that are associated with heart rate. Since heart rate is a marker of cardiovascular health, these findings could provide a better understanding of genetic regulation of heart beat and...
Microbes from the human mouth are telling Oak Ridge National Laboratory scientists something about periodontitis and more after they cracked the genetic code of bacteria linked to the condition. The finding, published in Proceedings of the National Academy of Sciences, profiles the SR1 bacteria...
A research team from the Korea Advanced Institute of Science and Technology (KAIST) released their results on the structure and molecular details of the neurodegenerative disease-associated protein Ataxin-1. Mutations in Ataxin-1 cause the neurological disease, Spinocerebella Ataxia Type 1...
The transistors and wires that power our electronic devices need to be mounted on a base material known as a "motherboard." Our human brain is not so different - neurons, the cells that transmit electrical and chemical signals, are connected to one another through synapses, similar to...
Biochemists at the University of Massachusetts Amherst including assistant professor Peter Chien recently gained new insight into how protein synthesis and degradation help to regulate the delicate ballet of cell division. In particular, they reveal how two proteins shelter each other in...
Greater than generate existence much less stressful, and additionally hallelujah invariably perfect for cash advance loan firms for instance 500 Fast Cash all-around which will stipulations mankind aside as to tricky periods, unfortunately a person have to mystery: Suppose i told you all sorts...
A discovery using stem cells from a patient with motor neurone disease could help research into treatments for the condition. The study used a patient's skin cells to create motor neurons - nerve cells that control muscle activity - and the cells that support them called astrocytes. Researchers...
Among the animals that are appealing "cover models" for scientific journals, lancelets don't spring readily to mind. Slender, limbless, primitive blobs that look pretty much the same end to end, lancelets "are extremely boring. I wouldn't recommend them for a home aquarium," says Enrico Nasi...
People who take cocaine over many years without becoming addicted have a brain structure which is significantly different from those individuals who developed cocaine-dependence, researchers have discovered. New research from the University of Cambridge has found that recreational drug users who...
Scientists at the Babraham Institute have gained a new understanding of when and how the DNA in developing egg and sperm cells is 'reset', in preparation for making a new embryo. It is well known that small chemical groups can be added to DNA to alter gene activity, these modifications to the...
For the first time, scientists have visualised an interaction between gluten and T-cells of the immune system, providing insight into how coeliac disease, which affects approximately 1 in 133 people, is triggered. Published today in Immunity, the discovery was led by Dr Hugh Reid and Professor...
My first offense, clean driving record also.. almost homless, behind on car payments and just got a job again.. what am I looking at.. I made the mistake after the game to go get some food.. I'm wortied I'm gonna lose everything and fall harder in the hole..
Using whole-genome sequencing, a team led by researchers from Harvard School of Public Health (HSPH) and the Broad Institute has traced the path of the E. coli outbreak that sickened thousands and killed over 50 people in Germany in summer 2011 and also caused a smaller outbreak in France. It is...
One of the big mysteries in biology is why cells age. Now scientists at the Salk Institute for Biological Studies report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain. The scientists discovered that certain proteins...
