Do caffeine's effects differ with or without sugar? (12/31/2014)

Do caffeine's effects differ with or without sugar?Consuming caffeinated or sugary drinks can affect the body's metabolism, causing changes in heart and respiratory rate and weight gain. The results of a new study exploring whether individuals respond differently to caffeinated drinks that do or do not contain sugar and to sugar alone are published in Journal of Caffeine Research: The International Multidisciplinary Journal of Caffeine Science. ...> Full Article

Toxic fruits hold the key to reproductive success (12/24/2014)

Toxic fruits hold the key to reproductive successScientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have now discovered why the fruit fly Drosophila sechellia is adapted to the toxic fruits of the morinda tree. Drosophila sechellia females carry a mutation in a gene that inhibits egg production. The flies have very low levels of L-DOPA, a precursor of the hormone dopamine, which controls fertility; interestingly, large amounts of L-DOPA are contained in morinda fruits. ...> Full Article


New therapy holds promise for restoring vision (12/23/2014)

New therapy holds promise for restoring visionUC Berkeley scientists developed a therapy to restore light sensitivity to retinas blinded by the death of photoreceptors, as in retinitis pigmentosa. They use a virus to insert a gene for an ion channel into surviving retinal cells. An injected chemical binds to the receptor and opens it when hit with light, making these cells respond to light. It works in mice and now dogs at PennVet, while mice see enough to follow visual cues. ...> Full Article


Macrophages chase neutrophils away from wounds to resolve inflammation (12/22/2014)

Macrophages chase neutrophils away from wounds to resolve inflammationMacrophages are best known for their Pac Man-like ability to gobble up cellular debris and pathogens in order to thwart infection. A new study describes how these immune cells also help resolve inflammation by inducing white blood cells called neutrophils to leave wounded tissue. ...> Full Article


Don't worry, be happy; just go to bed earlier (12/21/2014)

When you go to bed and how long you sleep at a time might actually make it difficult for you to stop worrying, according to researchers at Binghamton University. The study, led by Binghamton Anxiety Clinic Director Meredith Coles and graduate student Jacob Nota, found that people who sleep for shorter periods of time and go to bed very late at night are often overwhelmed with more negative thoughts than those who keep more regular sleeping hours. ...> Full Article


Don't worry, be happy: Just go to bed earlier (12/20/2014)

When you go to bed, and how long you sleep at a time, might actually make it difficult for you to stop worrying. So say Jacob Nota and Meredith Coles, who found that people who sleep for shorter periods of time and go to bed very late at night are often overwhelmed with more negative thoughts than those who keep more regular sleeping hours. The findings appear in Springer's journal Cognitive Therapy and Research. ...> Full Article

NIH-funded study is decoding blue light's mysterious ability to alter body's natural clock (12/18/2014)

NIH-funded study is decoding blue light's mysterious ability to alter body's natural clockBlue light bombards us, whether city lights, smartphones or tablets, says chemist Brian Zoltowski, Southern Methodist University, Dallas. Blue light knocks off-kilter the natural circadian clock in humans, plants and animals, and can result in health problems, sleep and mood disorders, drug addiction, crop disease, and even confused migratory animals. The National Institutes of Health has awarded a $320,500 grant to Zoltowski's lab to map the trajectory of blue lightwaves signaling the body's natural clock. ...> Full Article


Vitamin supplement successfully prevents noise-induced hearing loss (12/17/2014)

Researchers from Weill Cornell Medical College and the Gladstone Institutes have found a way to prevent noise-induced hearing loss in a mouse using a simple chemical compound that is a precursor to vitamin B3. This discovery has important implications not only for preventing hearing loss, but also potentially for treating some aging-related conditions that are linked to the same protein. ...> Full Article

The human eye can see 'invisible' infrared light (12/15/2014)

The human eye can see 'invisible' infrared lightScience textbooks say we can't see infrared light. Like X-rays and radio waves, infrared light waves are longer than the light waves in the visual spectrum. But an international team of researchers has found that under certain conditions, the retina can sense infrared light after all. ...> Full Article


The nutritionists within (12/15/2014)

The nutritionists withinMicrobial partners are important for the nutrition of many insects. They help detoxify and digest food, but also provide essential nutrients. Firebugs feed mainly on plant seeds that are poor sources of B vitamins. Bacterial symbionts in the insects' gut produce these vitamins and thereby ensure the host's metabolic stability. The insects actively harvest the vitamins from the bacteria by using specific enzymes that burst open the bacterial cell walls. ...> Full Article


Restrooms: Not as unhealthy as you might think (12/14/2014)

Microbial succession in a sterilized restroom begins with bacteria from the gut and the vagina, and is followed shortly by microbes from the skin. Restrooms are dominated by a stable community structure of skin and outdoor associated bacteria, with few pathogenic bacteria making them similar to other built environments such as your home. The research is published ahead of print in Applied and Environmental Microbiology. ...> Full Article

Best supporting actors in your ears? Research points to potential way to restore hearing (12/3/2014)

Best supporting actors in your ears? Research points to potential way to restore hearingThere's a cast of characters deep inside your ears -- many kinds of tiny cells working together to allow you to hear. The lead actors, called hair cells, play the crucial role in carrying sound signals to the brain. But new research shows that when it comes to restoring lost hearing ability, the spotlight may fall on some of the ear's supporting actors -- and their understudies. ...> Full Article
