Tiny Tampa Bay fish key to evolution of immune system

Researchers studying a lancelet, a tiny primitive fish found in Tampa Bay waters, have identified key immune system proteins that share similarities with those found in humans. The study's findings could lead to improved biodefense and biotechnology for cancer treatment and disorders like rheumatoid arthritis.

Uncovering DNA's 'sweet' secret

Biochemist Martin Egli and his team solved the X-ray crystal structure of homo-DNA, an artificial analog of DNA with a six-carbon sugar backbone. The study shows that fully hydroxylated six-carbon sugars are too bulky to produce a stable base-pairing system capable of carrying genetic information as efficiently as DNA.

Williams Syndrome, the brain and music

A study published in NeuroImage found structural abnormalities in the planum temporale of individuals with Williams syndrome, which may explain their enhanced auditory skills. Despite smaller brain volumes, the temporal lobe was found to be of normal volume, suggesting that other factors contribute to their unique abilities.

One-third of US youth not physically fit

According to a report in Archives of Pediatrics & Adolescent Medicine, approximately one-third of boys and girls aged 12-19 in the US do not meet physical fitness standards. The study found that regular physical activity is essential for maintaining good health, as low-fit youth are at increased risk of chronic diseases.

A new player in nuclear import of HIV-1

A new study has identified a key player in HIV-1's nuclear import process, revealing that host cell tRNA molecules facilitate the entry of the virus's reverse transcription complex into the nucleus. This finding sheds light on the complex mechanisms by which HIV-1 integrates its genetic material into host cells.

Short episodes of manic symptoms may indicate bipolar disorder in some youth

A study of 438 children and adolescents with bipolar spectrum disorders found that those with short episodes of mania were similar to those meeting full diagnostic criteria, suggesting a need for revised diagnostic criteria. The study's results will inform changes to the Diagnostic and Statistical Manual of Mental Disorders-IV.
