WEDNESDAY, April 24, 2019 (HealthDay News) -- Many older Americans may remember "Fantastic Voyage" -- the 1966 film where scientists and the vessel they were in shrank to microscopic size and traveled through the human body.

Now, science fiction may be getting closer to reality. Researchers say they've created a tiny medical robot that's able to navigate on its own in and around a bea...

WEDNESDAY, April 17, 2019 (HealthDay News) -- The advent of highly active antiretroviral therapy (HAART) in the 1990s revolutionized HIV/AIDS treatment.

But while it dramatically improves survival, some patients can develop troublesome side effects or even resistance to the potent pills.

So, the search for an alternative has continued.

Enter UB-421. An antibody tha...

WEDNESDAY, April 17, 2019 (HealthDay News) -- The death of brain cells may not be as sudden, or as irreversible, as previously believed.

WEDNESDAY, Feb. 20, 2019 (HealthDay News) -- Scientists say they've taken a first step toward creating a pacemaker that runs on the heart's own energy rather than batteries.

Pacemakers are electronic devices implanted to regulate your heartbeat -- usually because of a condition that slows your heart's normal rate. Traditional pacemakers have two parts: a battery-powered pulse generato...

WEDNESDAY, Feb. 20, 2019 (HealthDay News) -- An imbalance in the gut "microbiome" of people with lupus may be driving the chronic autoimmune disease as well as its flare-ups, new research suggests.

The microbiome is the trillions of helpful bacteria that coexist in the human digestive tract and elsewhere in the body.

Comparing gut bacteria from lupus patients with bacteria f...

TUESDAY, Jan. 8, 2019 (HealthDay News) -- Despite the terrifying plot lines of many a sci-fi film, there's no need to worry that germs in space might transform into ferocious, malevolent microbes that threaten the human race.

Quite the opposite, new research reveals.

The harsh conditions of galactic travel don't trigger genetic changes in bacteria that make them more danger...

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, Dec. 20, 2018 (HealthDay News) -- People with diabetes often don't have enough insulin-producing beta cells to control their blood sugar, but a combination of two novel drugs may coax the body into making more of these vital cells, an early study finds.

"People with autism do not l...

WEDNESDAY, Nov. 28, 2018 (HealthDay News) -- An experimental gene therapy for Parkinson's disease seems to work by rewiring key areas of the brain, a new study finds.

The researchers focused on 15 Parkinson's patients who, in an earlier trial, had received so-called GAD gene therapy. GAD is an enzyme that spurs the production of a brain chemical involved in movement control.

TUESDAY, Nov. 27, 2018 (HealthDay News) -- People with disabling back pain may one day receive replacement spinal discs grown from their own stem cells, researchers say.

Preliminary results in goats are encouraging, according to the University of Pennsylvania researchers who've been working toward this goal for about 15 years.

In their latest effort, the team implanted bi...
