The cheap diagnostic kit is made using a regular inkjet printer and could catch signs of malaria, tuberculosis and cancer earlier in the developing world

(Phys.org)--Physicists have discovered that dozens of 3-D knotted structures called "topological solitons," which have remained experimentally elusive for hundreds of years, can be created and frozen for long periods of ...

Scientists have discovered a long-term epigenetic memory switch that controls different modes of bacterial virulence, a bacterial survival strategy for outsmarting the human immune response. The study sheds new light on ...

Breast cancer patients with dense breast tissue have almost a two-fold increased risk of developing disease in the contralateral breast, according to new research.

Two studies are opening important new windows into understanding an untreatable group of common genetic disorders known as RASopathies that are characterized by distinct facial features, developmental delays, cognitive i...

The human mouth can harbor more than 700 different species of bacteria. Under normal circumstances these microbes co-exist with us as part of our resident oral microbiota. But when bacteria spread to other tissues via th...

New research may help to overcome life-threatening antibiotic-resistant bacteria in what the World Health Organization warns could become a 'post-antibiotic era.' Biologists combined different classes of antibiotics to k...

The new gene-editing tool CRISPR/Cas9 holds promise for new treatment of such genetic diseases as cystic fibrosis, muscular dystrophy and hemophilia. But to work well, it must be delivered across the cell membrane and in...

Scientists have discovered a better way to extract proteins from the membranes that encase them, making it easier to study how cells communicate with each other to create human health and disease.

Bacteria are not the sole cause of cavities; tooth resistance also plays an instrumental role. Researchers demonstrate that mutated genes lead to defects in the tooth enamel and can therefore encourage the development of...

An expectant mother's exposure to the endocrine-disrupting chemical bisphenol A (BPA) can raise her offspring's risk of obesity by reducing sensitivity to a hormone responsible for controlling appetite, according to a mo...

The marriage rate in the U.S. continues to decline and the view that marriage entails a "lack of freedom" is becoming more entrenched, particularly among younger men, according to researchers.

New experiments will help astronomers uncover the sources that helped make the universe transparent. When we peer through our telescopes into the cosmos, we can see stars and galaxies reaching back billions of years. Thi...

Superconductivity, where electrical currents course unhindered through a material, is one of modern physics' most intriguing scientific discoveries. It has many practical uses. Governments, industries, and health care an...

Unknown physics that could undermine quantum theory has been ruled out in a measurement guided by starlight emitted at least six centuries ago

Sitting may not be as deadly as previously thought, with new research ruling out sitting as a direct cause of diabetes.

Climate change doubters have seized upon a new accusation suggesting that scientists with NOAA manipulated temperature data in a 2015 study on climate change to reach a desired conclusion. The accusations, scientists sai...

Of the more than 700,000 Americans who suffer a heart attack each year, about a quarter go on to develop heart failure. Scientists don't fully understand how one condition leads to the other, but researchers have now dis...

Leading neuroscientists have clarified the role of a controversial immune system protein in Alzheimer's disease, showing it has opposing effects in early and late stages of the disease. Their discovery unites previous st...

The heavier someone is, the less likely they are to have what many people might call a "good death," with hospice care and a chance to die at home, a new study finds. And that difference comes with a financial, as well a...

Hyperalgesia refers to an increased sensitivity to pain. It can occur during alcohol withdrawal, and may contribute to a relapse to drinking. Alternative therapies such as acupuncture and electroacupuncture (EA; which co...

Research has used brain "organoids" -- tiny 3D models of human organs that scientists grow in a dish to study disease -- to identify root causes of Miller-Dieker Syndrome (MDS), a rare genetic disorder that causes fatal ...
