New sucker-footed bat discovered in Madagascar

...rests because the bat appears to have adapted very well to the large broad-leaf Ravenala that are often pioneering plants in zones where the original forests have been cleared and burned. "For now, we do not have to worry as much about the future of Myzopoda," said Steven M. Goodman, Field Museum fi...

New species of snapper discovered in Brazil

...und in the Caribbean and eastern United States, as well as the dog snapper caught by fishermen here in Brazil, but it is a distinct species with different markings and color." Twelve species of the family Lutjanidae, including the new discovery, are now identified in the western Atlantic Ocean. They in...

Microbes start immune response by sneaking inside cells

...about how best to design future human vaccines, as well as drugs that could more precisely target the body’s inflammatory response in rheumatoid arthritis and some other autoimmune diseases. “In our study, the presence of bacterial microbes inside the cell is what triggers the immune response. That cre...

Trusting your instincts leads you to the right answer

...tudy has found that you are more likely to perform well if you do not think too hard and instead trust your instincts. The research, published online today in the journal Current Biology, shows that, in some cases, instinctive snap decisions are more reliable than decisions taken using higher-level cognit...

Rapid, Low-Cost DNA Testing

..., the analyte contains the DNA target sequences as well as other DNA sequences, and the assay filters out only the targets. Professor Rothberg's assay is based on the electrostatic properties of DNA. The principle underlying the method is that single-stranded DNA and double-stranded DNA have significan...

Study shows hope for early diagnosis of Alzheimer's

... hear a series of low- and high-frequency tones as well as some novel sounds. Patients were asked to respond by pressing a button every time they heard the high frequency tone, also known as the “oddball?tone, which generates ERPs in the EEG. Generally, in the ERP of a person without Alzheimer’s, that res...

Biologists develop large gene dataset for rice plant

...ion (via messenger ribonucleic acids, or mRNAs) as well as small ribonucleic acids (small RNAs) in rice. The analysis of rice was based on gene sequences representing nearly 47 million mRNA molecules and three million small RNAs, a larger dataset than has been reported for any other plant species. S...

Mailman School of Public Health researchers report blood DNA can be early predictor of liver cancer

...as age and hepatitis B and C virus infections, are well documented risk factors for the development of HCC. According to the study findings, these factors coupled with smoking and alcohol status, and alterations found in this study in serum DNA, resulted in an overall predictive accuracy of 89% for detec...

Fighting to keep Darwin in the classroom

... Springer's new journal is very timely and indeed well overdue. It is sure to play a major role in science education in the United States and beyond." Telmo Pievani, Professor of Philosophy of Science at the University of Milan, Italy, said, "Outreach and Education in Evolution is absolutely opportun...

Current cancer stem cell theory holds that tumors are comprised of a variety of cell types. Among them is a small subset of rather primitive cells that, like other stem cells in t...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

The dendritic cell vaccination strategy combines a cancer protein with the patient’s own dendritic immune cells. These cells are antigen presenting cells that, in effect, advertise the presence of the ant...
