For several decades now, one of the buzz words in the medical field has been ‘stem cell’. It has been said to aid in treating illnesses like multiple sclerosis, amyotrophic lateral sclerosis, Alzheimer’s disease, and heart diseases.

For the past three years, researchers at the Hubrecht Institute in the Netherlands have been painstakingly cataloging and mapping all the proliferating cells found in mouse hearts, looking for cardiac stem cells. The elusive cells should theoretically be able to repair damaged heart muscle, so the stakes in finding them have been high.

This week, however, Proceedings of the National Academy of Sciences is scheduled to announce the results of the Hubrecht team’s work: no evidence of cardiac stem cells at all.

During 2014’s Ebola outbreak, there were no treatments on hand to fight the virus. Now, researchers have found a human protein that could change that.

An injection capable of halting the progress of Alzheimer’s could be available to patients within a decade, Britain’s leading dementia organisation predicts.

The Alzheimer’s Society says a series of recent breakthroughs in treatments that disrupt harmful genes has brought scientists to a “tipping point” in their fight against the disease.

For decades, researchers have sought without success a treatment for Alzheimer’s based on targeting damaging proteins that build up in the brain.

A quick and easy test devised by scientists from the University of Queensland could transform cancer diagnosis as we know it.

Cancer is a difficult disease to diagnose because different types are characterised by different signatures. Until now, scientists have been unable to find a unique signature common to all forms of cancer that would set it apart from healthy cells.

That’s what University of Queensland researchers Dr Laura Carrascosa, Dr Abu Sina and Professor Matt Trau have addressed. They have discovered a unique DNA nanostructure that seems to be common to all types of cancer and is visible when cancer cells are placed in water.

Self-assembling silver tubes might someday wire up your clothes.

Inspired by blood vessels, the silver nanowires practically manufacture themselves.

In 1961, Nancy Grace Roman was already the first Chief of Astronomy in NASA’s Office of Space Science. She developed that program in a time before the second wave of the Women’s Movement in the United States began, when banks often refused women credit in their own names and there was still an active medical debate about whether women could ever physically endure spaceflight someday. But Roman opened the skies to humanity in new ways without ever leaving the ground.

She earned her Ph.D. in astronomy at the University of Chicago in 1949 and worked at the Yerkes Observatory there for six years afterward. She joined the radio astronomy group at the Naval Research Laboratory, becoming the head of the microwave spectroscopy section. As she recalled in 1980 in an oral history interview with National Air and Space Museum curator David DeVorkin, when she heard that NASA might set up a space astronomy program, she wanted to lead it: “The idea of coming in with an absolutely clean slate to set up a program that I thought was likely to influence astronomy for 50 years was just a challenge that I couldn’t turn down. That’s all there is to it.” She joined NASA in 1959, just after the agency’s founding.

In 2016, a mysterious illness spread inside the National Institutes of Health’s Clinical Center, the U.S. government’s most prominent research hospital, in Bethesda, Maryland. Patients were somehow being sickened by an antibiotic-resistant strain of bacteria that practically never causes disease in humans. Two years later, a new study seems to finally have confirmed where this bug likely came from: the hospital’s own plumbing.

During a six-month period in 2016, six patients came down with infections caused by Sphingomonas bacteria. Four of the patients had an antibiotic-resistant strain of a particular species, Sphingomonas koreensis, which was first discovered in some of Korea’s natural mineral water spots in the early 2000s.

WASHINGTON (AP) — Most Americans say it would be OK to use gene-editing technology to create babies protected against a variety of diseases — but a new poll shows they’d draw the line at changing DNA so children are born smarter, faster or taller.

A month after startling claims of the births of the world’s first gene-edited babies in China, the poll by The Associated Press-NORC Center for Public Affairs Research finds people are torn between the medical promise of a technology powerful enough to alter human heredity and concerns over whether it will be used ethically.

Jaron Keener, a 31-year-old exhibit designer at Pittsburgh’s Carnegie Museum of Natural History, said he’s opposed to “rich people being able to create designer babies.”
