Did rats spread SARS in Amoy Gardens?

The rat vector hypothesis suggests that rats may have spread SARS in the Amoy Gardens apartment block. Epidemiological case-control studies could be undertaken to identify behavioural risk factors and possible mechanisms for rat-to-man infections. This hypothesis is a strong possibility that needs to be further explored.

Increased prevalence of diabetes - not all bad news

A recent study found that diabetes prevalence increased globally between 1993 and 1999. However, mortality rates from diabetes decreased by 3% during this period. The researchers suggest that earlier treatment and improved healthcare may contribute to the decline in mortality rates.

Nitrous oxide record sheds light on glacial carbon dioxide

A new record of nitrous oxide concentration variations reveals that both land and ocean bacteria contributed equally to atmospheric emissions during glacial periods. This finding contradicts the long-held theory of oceanic storage being responsible for low atmospheric carbon dioxide levels.

New solid-state power switch safeguards electric service

Researchers at Virginia Tech have developed a high-power semiconductor switch called the Emitter Turn-off (ETO) Thyristor, suitable for fast and dynamic voltage support in the nation's congested power grid. The ETO switch offers fast switching speed, rugged turn-off capacity, and voltage control, reducing energy storage elements and size.

How a nightcap may hinder rather than help your sleep

Researchers found that recovering alcoholics experience persistent sleep disruptions for many months after quitting drinking, with problems with sleep onset being worse than sleep maintenance. Many former alcoholics reported pre-existing sleep problems that predated their alcohol dependence.

Interstitial cystitis study finds limited benefit in two oral drugs

A recent study tested pentosan polysulfate sodium and hydroxyzine hydrochloride on patients with interstitial cystitis, a debilitating condition affecting millions. The trial found that neither drug provided statistically significant relief for patients, but gained valuable information for future clinical trials.

Smoking causes half the tuberculosis deaths in Indian men

A study of 43,000 Indian men found that smoking increases mortality rates from tuberculosis (TB) by four times compared to non-smokers. The researchers also discovered that about a quarter of smokers die prematurely at ages 25-69, losing an average of 20 years of life expectancy.

The genetic complexities of sensation-seeking behavior in alcoholic men

A recent study found an association between the DdeI polymorphism of the DRD1 gene and sensation seeking among alcoholic males. The research suggests that genetic factors, such as this specific dopamine receptor gene, may play a role in understanding the complex disorder of alcoholism.

Researchers one step closer to Holy Grail of neurobiology

Researchers at Rockefeller University have developed a mathematical equation that combines generalized arousal with specific forms of arousal, such as sex and hunger. The study found that genetic changes in mice lacking estrogen receptors can influence overall arousal, providing new insights into the neural mechanisms underlying arousal.

Modifier gene controls severity of neurological disease in mice

Researchers have discovered a modifier gene, Scnm1, that affects the severity of neurological diseases in mice and is also present in humans. The study found that when the genetic code for this gene is transcribed, it can produce non-functional protein that alters the physical effects of inherited diseases.

Research: Coral reefs' decline actually began centuries ago

Researchers found that coral reef declines followed the same pattern globally, starting with large predators and herbivores, followed by smaller animals and finally sea grasses. The study provides a yardstick for conservation efforts, offering hope for restoring ecosystems with strong management decisions.
