Mounting research continues to show the links between the health of the gut and that of the brain. Now, a new study from Lund University in Sweden finds that unhealthy intestinal flora can accelerate the development of Alzheimer’s disease.
As the nascent field of genetic testing advances, expectant parents face a dizzying array of new and difficult questions. Would you want to know if your child will have Down syndrome? Or if your baby is genetically predisposed to Alzheimer’s disease? What about if the fetus has a gene duplication that might mean nothing ― or could spell a serious genetic disorder?
The sci-fi world of designer babies may not be here yet, but modern genetic technology is already fundamentally changing pregnancy and parenting.

What's for dinner? For some Brazilian vampire bats, these days it's human blood.
That's the surprising outcome of my research, recently published in the Acta Chiropterologica journal, which revealed that the hairy-legged vampire bat of Pernambuco, Brazil, has developed an appetite for human blood over that of other possible prey.
Most people are quick to dismiss internet trolls as completely unlike themselves ― the fabled 400-pound guy sitting on his bed, for instance.
And with partisan rage taking over Twitter alongside the election of a troller in chief, it can feel like we’re living in the golden age of internet trolling: Posting inflammatory and offensive comments online for the purpose of provoking others has become a sadly common phenomenon.
There is an abundance of mysteries here on planet Earth. For example, what ever happened to the $2 bill, who comes up with all those funny bumper stickers, and how did the millions of pussy hats get made so fast?
Then there is this question: Why would anyone want to live on Mars?
Some of the most intelligent people alive - among them,, billionaire Elon Musk, fellow billionaire Sir Richard Branson and theoretical physicist Stephen Hawking - want us to colonize Mars.

CAPE CANAVERAL, Fla. (Reuters) - A SpaceX Falcon rocket blasted off on Sunday from a Florida launch pad once used to send NASA astronauts to the moon, a step forward for billionaire entrepreneur Elon Musk and his company’s goal of ferrying astronauts to the International Space Station.
(Reuters Health) - Too many U.S. adults are not getting vaccinated, putting themselves and others at risk, immunization experts say.
According to the latest available data, about 44 percent of adults over age 19 had a flu shot; 20 percent had a TDAP vaccine, which protects against tetanus, diphtheria and pertussis; and 20 percent of 19-to-64-year-olds at risk of pneumonia had that vaccine (compared to 60 percent of those over 65).
CHICAGO (Reuters) - Powerful gene editing tools may one day be used on human embryos, eggs and sperm to remove genes that cause inherited diseases, according to a report by U.S. scientists and ethicists released on Tuesday.
After more than 130 years, wild bison have returned to Canada’s oldest national park.
Humans had hunted the animal almost to extinction, and they had not been seen in the Banff National Park area since before it was established in 1885.
Have we really discovered other "Earth-like" planets orbiting around other stars? Understanding what we do and do not know about exoplanets is the key to answering this question. ESO/L. Calcada/N. Risinger/Reuters

In 1950, physicist Enrico Fermi famously asked, "Where are they?" as a kind of lament about the lack of observational evidence for alien intelligence in our universe.
After a few shaky days, Cincinnati Zoo & Botanical Garden's premature baby hippo, Fiona, took her wobbly first steps in the wee hours of Sunday morning. Hippo's are nocturnal, so it's not surprising that she would get a burst of energy when most people are sleeping.
