The first baby boom

Researchers Bocquet-Appel and Naji found a sudden 20-30% increase in birth rates worldwide during the Neolithic period, as indicated by an abrupt change in skeletal evidence. This finding corroborates a global demographic transition, with archaeological evidence showing parallels between Europe, North Africa, and the Americas.

Study sheds new light on causes of common STD

The study found that Chlamydial infection was common in both heterosexual and homosexual men with NGU, with C. trachomatis and M. genitalium being associated with unprotected vaginal sex. Oral-genital contact may be an important mechanism of NGU pathogen transmission, according to the findings.

New UCSF study finds that obesity is a risk factor for kidney failure

A new UCSF study found that obesity is a significant risk factor for kidney failure, with the morbidly obese having up to seven times greater risk than normal-weight individuals. The research, published in Annals of Internal Medicine, suggests that weight loss may be a potential way to reduce kidney failure risk.

Income level may predict response to depression treatment

Research suggests that people in middle-income areas are more likely to respond to depression treatment than those in low-income areas. The study found an inverse relationship between median household income and suicidality, with low-income areas having a higher risk of suicidal behavior.

Promising new treatment for ulcerative colitis sufferers

A promising new therapy has been approved by the FDA for patients with moderate to severe ulcerative colitis, offering improved lives through reduced inflammation and increased mobility. Nearly 70% of patients experienced clinical response and remission within a year of treatment.

Research tracks whales by listening to sounds

Scientists use hydrophones to distinguish sounds made by different whale species, finding rare right whale sightings in the Gulf of Alaska and distinct 'dialects' among species. The study also reveals surprisingly robust populations of sperm whales during winter months.

Annals of Internal Medicine tip sheet for Jan. 3, 2006

A survey of internists reveals the most common reasons for recertification are to maintain professional image and update knowledge. In contrast, a review finds no evidence that oral nutritional supplements help elderly patients in a home setting. Meanwhile, unsupervised walking at home can slow decline from peripheral arterial disease.

Perinatal complications linked to eating disorders

Researchers found a correlation between obstetric complications and anorexia nervosa, with specific complications increasing the risk of developing the disorder. The study suggests that prenatal factors may contribute to the development of eating disorders by impairing neurodevelopment or causing neonatal brain damage.

An elephant tail

Researchers analyzed chemicals in elephant tail hair to determine their diet and movements, revealing the need for secure habitats to protect endangered species. The study aims to inform land use planning and minimize conflicts between humans and elephants.

Taking an alternative approach to HIV vaccination

Researchers have discovered a novel strategy for enhancing HIV vaccination by silencing the SOCS1 molecule in dendritic cells, which can induce a good memory immune response and boost the potency of HIV DNA vaccination. This approach has potential for therapeutic and prophylactic vaccines against HIV and other pathogens.

New weapon in battle against osteoporosis

Researchers have discovered that cannabinoid receptors, particularly CB2, play a crucial role in regulating bone density and reducing the risk of osteoporosis. The study found that mice with a specific gene defect exhibit lower bone density, while patients carrying a variant of the CB2 gene have a three-fold higher risk of osteoporosis.

Underwater listening devices yield discoveries about endangered large whales

The use of underwater listening devices has yielded surprising discoveries about the movements and calling behavior of endangered large whales in Alaskan waters.
