Sudden change in social status triggers genetic response in male fish, study finds

...id behavioral responses to social opportunity were matched by a rapid genomic response in the brain," Fernald says. "We didn't expect to get changes in gene expression in the brain so early in the process, just 20 minutes after the male has seen the prospect for social change." These results suggest that s...

Preventing a pandemic: Study suggests strategies for containing a flu outbreak

...e the outbreak, even with a vaccine that is poorly matched to the actual virus strain, increased the effectiveness of TAP and GTAP. For even higher viral reproductive numbers, household quarantines would also be necessary to contain the virus. A combination of TAP, prevaccination and quarantine could contai...

A step toward the $1,000 personal genome using readily available lab equipment

...ce of base pairs. In their study, the researchers matched the sequence information against a reference genome, finding genetic variation in the bacterial DNA that had evolved in the lab. "These developments give the feeling that improvements are coming very quickly," said HMS professor of genetics Church, ...

Progress on HIV/AIDS significant but insufficient

Monkeys understand numbers across senses

... overwhelmingly chose to look at video images that matched the number of monkeys they were hearing. This result is consistent with previous studies that both animals and infants tend to look preferentially at a visual stimulus that matches the sound they are hearing. According to Brannon, previous studies h...

New markers of climate change

... rainfall, the levels of these two isotopes can be matched against the changing environments to which the plants have been exposed. If successful, these plants could be used as bioindicators of climate change throughout the tropics. Monica will be presenting her work at the Society for Experimental Biology ...

Temperature regulates circadian clock in zebrafish

...ression profiles during the high temperature phase matched those seen during a light phase when animals experienced light-dark cycles. Zebrafish cell lines also proved valuable tools for studying temperature response, showing a similar pattern of clock gene expression during cycles of small temperature cha...

New technique rapidly detects illness-causing bacteria

...mentary DNA -- known as probes -- that are exactly matched to stick to the rRNA target sites. These sequences are then reproduced as genetic material by a biotech company. To test for the presence of scarlet fever-causing bacteria, a sample of rRNA is placed in a test tube with two of the manufactured probe...

A novel virus for croup

...inance in late autumn and earlier winter, that are matched by patterns of HCoV-NL63 occurrence. This systematic association of croup with HCoV-NL63 is particularly timely as the newly identified virus has spread worldwide, reported in Australia, Japan, the US and Canada. The study will also contribute towa...

Drawing with DNA: 'Bioart' illuminates genomics

...00 base pairs, or "letters" of genetic code, to be matched against the billions of letters for known genes. Searching for similarities that can shed light on functional or evolutionary relationships, scientists routinely use BLAST to churn through and produce vast amounts of data. Everyday applications inclu...

Spiders help scientists discover how muscles relax

Kenneth Taylor's research group at Florida State University reported the atomic structure of the smooth muscle myosin molecules. The similarity suggests, Padron said, that the interacting head str...

Identification of specific genes predicts which patients will respond to Hepatitis C treatment

In order to define which genes discriminate between those patients who respond to therapy to those who do not, microarray technolog...

Bioinformatics reveals new gene regulation system

... pattern as the NrdR-box. Only one protein cluster matched the pattern, and it represented a family of proteins that shared traits of transcription factors. To strengthen the prediction that these proteins were the transcription factors that bind the NrdR-box, the team used another comparative genomic tool ...

Where Bacteria Get Their Genes

This showed that the widespread mechanism of lateral gene transfer does not interfere with the traditional approach of using family trees to infer relationship...

Random gene expression may drive HIV into hiding

...models they tested, only one produced results that matched those seen experimentally in the infected cells. In this model, after HIV's RNA enters a host cell, it is copied into DNA, and then a little bit of Tat is made before the virus integrates into the host genome. At this point, Tat must be chemically m...
