A Cosmic Fossil? Brilliant But Fuzzy Galaxy May Be Aftermath Of Multi-Galaxy Collision
The galaxy NGC 1132 is most likely a cosmic fossil -- the aftermath of an enormous multi-galactic pile-up, where the carnage of collision after collision has built up a brilliant but fuzzy giant elliptical galaxy far outshining typical galaxies. In visible light NGC 1132 appears as a single, isolated, giant elliptical galaxy, but this is only the tip of the iceberg.
Smoking Linked To Sleep Disturbances
Cigarette smokers are four times as likely as nonsmokers to report feeling unrested after a night's sleep. Smokers also spend less time in deep sleep and more time in light sleep than nonsmokers. Researchers speculate that the stimulating effects of nicotine could cause smokers to experience nicotine withdrawal each night, which may contribute to disturbances in sleep.
Tipping Elements In Earth's Climate System
A number of key components of the Earth's climate system could pass their 'tipping point'. Earth's climate system is at risk of being pushed past critical thresholds, so that important components may "tip". In other words, the Earth is approaching the point where even small changes can have large long-term consequences on human and ecological systems.
Lifetime Medical Costs Of Obese People Actually Lower Than Costs For Healthy And Fit, Mathematical Model Shows
What are the lifetime medical costs associated with obesity? Researchers found that the group of healthy, never-smoking individuals had the highest lifetime healthcare costs, because they lived the longest and developed diseases associated with aging; healthcare costs were lowest for the smokers, and intermediate for the group of obese never-smokers.
Giving Mice A Cold Virus Offers Hope Of New Asthma Treatments
Scientists have been able to recreate rhinovirus infection, which is behind most common colds, in a small animal for the first time. For fifty years since they were discovered, it had been thought that rhinoviruses could only infect humans and chimpanzees. Rhinoviruses are an unwelcome inconvenience for the majority of the population as they cause around three quarters of common colds.
Treating Acne: Two Different Acid Peels Are Both Effective, Study Finds
Chemical peels using either alpha-hydroxy acid or beta-hydroxy acid are both highly effective in treating mild to moderately severe facial acne, researchers have found -- the first study to compare the two different types of acid peels as therapies for the skin disorder. Peels using beta-hydroxy acid (or BHA) had slightly fewer side effects and results that lasted a bit longer than did peels using alpha-hydroxy acid (or AHA), the study found.
