What women eat before conception can alter baby's genes: study - Yahoo News - 0 views

Surgery Could Give Men Wombs of Their Own Within 5 Years - 0 views

  •  
    Will men be able to give birth sooner than, well, never? (Credit Yahoo Health/iStock) That's the question provoked by last week's announcement that the Cleveland Clinic is performing uterus transplant surgery on women who were born without a womb or whose uterus is diseased or malfunctioning. Hearing the news, we, and some of you, wondered: If science can transplant a uterus into a woman, can it transplant one into a man?

Unique Animals Found at East Coast Methane Seep - Yahoo! News - 0 views

  •  
    While surveying the seafloor last fall, a research vessel spotted bubbles rising from the depths. Now, another ship has gone back to investigate, and found a variety of life on the seafloor surrounding a methane seep, according to an update from researchers with the National Oceanic and Atmospheric Administration (NOAA).

Having Too Much of This Could Lead to Depression - Yahoo News - 0 views

  •  
    Sure, we know insufficient serotonin levels get a bad rap when it comes to depression, but that's like blaming one person in a full-scale riot. Depression isn't caused by only one factor. In fact, study co-author Elyse Aurbach says we're probably not getting to the core of why people are depressed because "the brain is immensely complex." In this study, the research team conducted eight experiments (four on animal brains, four on brains of the deceased human kind) of varying sample sizes - from 20 to 90 brains in each - and found that the brains of deceased humans who'd been depressed had increased levels of hippocampal FGF9 and that live animals with increased FGF9 levels demonstrated depressive, anxious behavior. "This is not just a correlation," study leader Huda Akil of the University of Michigan says. Less really may be more, at least when it comes to FGF9.

Giant, ancient viruses are thawing out in Siberia - and they're changing everything we ... - 0 views

  •  
    Last month, researchers announced they were studying a 30,000-year-old giant virus called Mollivirus sibericum that they found in melted Siberian permafrost. The virus was functional and able to infect amoeba. This isn't the first time researchers have found big viruses that have challenged what we thought we knew about the tiny invaders. Mimivirus, discovered in 2003, has 1,200 genes and is twice the width of traditional viruses.

Research Shows Links Between Obesity and 8 Additional Cancers - Yahoo - 0 views

  •  
    Researchers from the World Health Organization's International Agency for Research on Cancer (IARC) looked at more than 1,000 epidemiological studies and found that "excess body fatness" is also linked to the risk of developing gastric, liver, gallbladder, pancreatic, ovarian, thyroid, blood (multiple myeloma) and brain (meningioma) cancers.

Giant Virus Resurrected from Permafrost After 30,000 Years - Yahoo News - 0 views

  •  
    In recent years, Claverie and his colleagues have discovered a host of giant viruses, which are as big as bacteria but lack characteristic cellular machinery and metabolism of those microorganisms. At least one family of these viruses likely evolved from single-celled parasites after losing essential genes, although the origins of other giant viruses remain a mystery, Claverie said.

GMO controversy explained - Yahoo News - 0 views

  •  
    GMOs are organisms that have had their DNA modified through genetic engineering. This is often done by taking a gene from one organism and putting it into another one to alter it in a desirable way. For example, when genetic engineers want to create a corn crop that is resistant to pests, they seek out the trait in Bacillus thuringiensis (Bt) soil bacteria that naturally acts as a pesticide. From there, engineers isolate the gene responsible for that trait and directly insert it into the corn's DNA. This corn is then bred with other corn until it's ready to be produced for consumption.

Dad's genes dominate: study - Yahoo News - 0 views

  •  
    Even if you look like your mother, an innovative study suggests that not only humans but, in fact, all mammals are genetically more like Dad. We inherit equal amounts of genetic material from each parent, yet that coming from our father's side is more likely to take action, according to the study that was published in the journal Nature Genetics.

NASA simulation shows a year in the life of Earth's CO2 - Yahoo News - 0 views

10 Signs You Have an Underactive Thyroid - Yahoo News - 0 views

  •  
    Some thyroid 101 background: Your thyroid gland is the butterfly-shaped gland at the base of your neck that secretes two all-important hormones that control major bodily functions (including how you use energy, regulate body temperature, and digest food) and organs (including the heart, brain, liver, kidneys and skin). But with hypothyroidism, your body can have normal to low thyroxine hormone levels and elevated thyroid stimulating hormone (TSH) levels. These high TSH levels are a result of an overworked pituitary gland that is trying to elevate the hormone levels in an inadequately responsive thyroid.

The untreatable Zika virus just made its way into another US territory - and it's not l... - 0 views

  •  
    The CDC released travel health notices Tuesday that named two more places in which the disease has spread via mosquito bites: The US Virgin Islands and the Dominican Republic.  The Zika virus is primarily transmitted by Aedes aegypti, the type of mosquito responsible for spreading dengue, yellow fever, and a whole host of other tropical infectious diseases. Originally identified in 1947 in Uganda, Zika was relatively unknown until 2007, when there was an outbreak of the virus in Micronesia. The mosquitoes pick up the virus from infected people, according to the CDC.

Radiation from Japan nuclear disaster spreads off U.S. shores - Yahoo News - 0 views

  •  
    PORTLAND, Ore. (Reuters) - Radiation from Japan's 2011 nuclear disaster has spread off North American shores and contamination is increasing at previously identified sites, although levels are still too low to threaten human or ocean life, scientists said on Thursday. Tests of hundreds of samples of Pacific Ocean water confirmed that Japan's Fukushima nuclear power plant continues to leak radioactive isotopes more than four years after its meltdown, said Ken Buesseler, marine radiochemist with the Woods Hole Oceanographic Institution.

Corrected: U.S. sees first case of bacteria resistant to last-resort antibiotic - 0 views

  •  
    "We risk being in a post-antibiotic world," said Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention, referring to the urinary tract infection of a 49-year-old Pennsylvania woman who had not traveled within the prior five months. Frieden, speaking at a National Press Club luncheon in Washington, D.C., said the bacteria was resistant to colistin, an antibiotic that is reserved for use against "nightmare bacteria."

Scientists have found an exciting new clue about how 'super-agers' stay sharp as they age - 0 views

  •  
    Research has shown that some older people stay sharp into old age and retain the ability to recall personal experiences with just as much accuracy as their middle-aged peers. The brains of these so-called "super-agers" look distinct, too: Their gray-matter-rich outer layer, or cortex, is thicker.
