HIV-1 spread through six transmission lines in the UK

...rus has subsequently spread and evolved. However, given that the first UK cases of AIDS reported in 1982 were probably infected within a window of 10 years prior to that time, the currently circulating strains may not represent the first HIV-1 lineages within the UK . If earlier strains existed they may h...

GeneNotes - A novel information management software for biologists

... integrated gene annotations to (a) identify genes given various types of gene IDs (e.g., RefSeq ID, GenBank ID, etc.), and (b) provide quick views of genes. GeneNotes is free for academic usage. The program and the tutorials are available at: http://bayes.fas.harvard.edu/genenotes/. GeneNotes provides a ...

Glow-in-the-dark zebrafish at UH hold keys to biological clocks

...ith an instrument called a luminometer. "This has given us the tool we need to find other parts of systems that influence biological clocks," Cahill said. "We are optimistic that this will shed light upon such things as reproduction in other light-dependent animals." These findings have laid the groundwo...

Sickle cell and protection against malaria

...i, Kenya, show that the protection against malaria given by carrying the gene for sickle cell haemoglobin may involve the immune system. Studying a group of children and adults in the Kilifi District of coastal Kenya, they found that this protection increased during childhood up to age 10, and then decline...

These officials "were given unrestricted educational grants that were deposited into an off-the-books account - unregistered, unmonitored, literally operated out of a drawer." The officials, he said, were responsible for writing guidelines for the treatment of patients in the s...

Study reveals new technique for fingerprinting environmental samples

This finding is crucial for studies of microbes in the wild since the sheer number of different organisms present in nearly all environments makes it a daunting task t...

Grasping metaphors: UC San Diego research ties brain area to figures of speech

"While it would be premature t...

Protein helps regulate the genes of embryonic stem cells

...he precise nature of the histone modification, any given gene associated with modified histones is marked to be turned on or off. In the study, eed is the first protein shown to be required for the addition of a single methyl group to histone H3, said Montgomery. Knowing which proteins are responsible for...

NSAID drug protects against intestinal tumors in mice, despite poor diet and gene losses

The researchers then looked at the role that diet plays when expression of two tumor suppressor genes is reduced. The researchers mated mice that had on...

To sea or not to sea: When it comes to salmon sex, size sometimes doesn't matter

The lopsided brain: Attention bias is shared by humans and birds

In the past, such communication via the corpus collosum has been thought to form the basis for asymmetries...

Master gene controls healing of skin in fruit flies and mammals
