TUESDAY, June 18, 2019 (HealthDay News) -- For women, predicting when they'll reach menopause is anyone's guess. But if you want to get some foresight, you should ask your mother.

For most women, menopause begins at around 52. But for thousands of women it starts much later, and for some, a lot earlier. Those whose menopause starts later may also be looking at a longer life expectancy...

TUESDAY, June 11, 2019 (HealthDay News) -- Can a DNA test predict a person's future heart health? Perhaps, researchers say.

A team of Canadian researchers found that by analyzing a person's entire genome, it might be possible to predict their future heart disease risk.

The so-called "polygenic risk score" analysis looks for key heart disease indicators -- genetic "biomark...

SUNDAY, March 24, 2019 (HealthDay News) -- When couples experience recurrent pregnancy loss, it's natural for them to want to know why. Now, a new study suggests that sperm DNA damage could be a factor.

Recurrent pregnancy loss is defined as the consecutive loss of three or more pregnancies before 20 weeks' gestation. It affects up to 2 percent of couples a...

FRIDAY, Jan. 4, 2019 (HealthDay News) -- A program that maps out the genes of newborns has allowed researchers to identify risks for some inherited childhood conditions, many of which can be prevented.

The so-called BabySeq Project discovered that slightly more than 9 percent of infants carry genes that put them at risk for medical conditions as they reach childhood.

"The Ba...

THURSDAY, Oct. 4, 2018 (HealthDay News) -- Mating with Neanderthals helped boost modern humans' ability to fight novel viruses in Europe and Asia, a new study contends.

Before vanishing about 40,000 years ago, Neanderthals interbred with modern humans who had migrated out of Africa. As a result, many modern Europeans and Asians have about 2 percent of Neanderthal DNA in their genomes,...

TUESDAY, Oct. 2, 2018 (HealthDay News) -- Only a small percentage of Americans have had their DNA analyzed -- but many are tempted to try it, according to new research.

For the study, University of Michigan researchers surveyed nearly 1,000 adults aged 50 to 64. While curious about their ancestry or health risks, the majority said they fear they'll worry excessively if they learn the...

TUESDAY, Aug. 21, 2018 (HealthDay News) -- A blood test can predict which lymphoma patients will respond well to normal treatment and which may need a more aggressive approach, researchers report.

Their study included 217 patients with diffuse large B cell lymphoma, the most common type of the blood cancer non-Hodgkin lymphoma.

The blood test checks levels of circulating tum...

WEDNESDAY, Jan. 24, 2018 (HealthDay News) -- The world's first genetically identical monkey clones have been created by Chinese scientists, who say they've broken barriers to human cloning.

But both the scientists and other experts say it's highly unlikely this advance will result in human clones in the foreseeable future.

The researchers, instead, are touting the potential ...

THURSDAY, Jan. 4, 2018 (HealthDay News) -- The mummified remains of an Italian boy who died 450 years ago suggest the hepatitis B virus has infected humans for centuries.

The child died in the 16th century. And prior testing suggested smallpox killed him.

But a new analysis evaluated DNA samples from the boy's bone and skin. This second look led investigators to conclude th...

TUESDAY, Dec. 5, 2017 (HealthDay News) -- Alzheimer's disease has long remained a deadly mystery.

But scientists say they've now pinpointed a rare piece of DNA that may shield against the illness -- even in people who are otherwise at high risk.

The discovery may explain why some people with known genetic risk factors don't develop Alzheimer's, the study authors said.

...

MONDAY, Nov. 13, 2017 (HealthDay News) -- There's such a thing as too much information when it comes to learning about your genes, two new studies suggest.

In one study, participants thought they were learning about their genetic risk for depression, not knowing that the test results they were given had been made up at random.

The study participants who were told they had a...
