A study of almost 5,000 Latin American-born residents of Los Angeles County found that 1.24 percent tested positive for Chagas disease, a parasitic infection that can cause life-threatening heart damage if not treated ea...

An anomaly in the number of antineutrinos produced by nuclear power plants was a result of a modeling error, not a hint of new physics.

(Lund University) Researchers from Lund University in Sweden have succeeded in producing nanotubes from a single building block using so-called molecular self-recognition. The tube can also change shape depending on the ...

A researcher has been studying how the mouthparts of butterflies and moths work since 2010. His research shows that the method in which flies and butterflies ingest liquids into their own bodies for nourishment may be us...

Traffic-related air pollution may increase risk of developing cardiovascular diseases through its effects on high-density lipoprotein (HDL), also known as 'good' cholesterol. US middle-aged and older adults living in are...

The first 1,000 days after conception strongly influence a person's life expectancy and disease susceptibility, research shows. The primary marker used to identify early life stress is low birth weight. But low birth wei...

Women with some characteristics commonly thought to increase pregnancy risks -- being over age 35; being overweight; and in some cases, having a vaginal birth after a cesarean section -- tend to have good outcomes when t...

In the search for extraterrestrial life, one of the most promising candidates so far is the tiny moon Enceladus. Research appearing today in the AAAS journal Science includes exciting new evidence of this promise--the de...

A method that uses the gene-editing tool CRISPR to recognise certain DNA sequences could make it quick and cheap to test for pathogens or genetic variants

It's harder than you think to make up a random sequence. Our ability to do so changes with age - and could give insight into cognitive decline

A new experiment to measure the behavior of muons in magnetic fields could reveal unknown particles --

The bacterium that causes gonorrhea infects the female reproductive tract by breaking connections between cells in the tract's protective lining, according to new research.

After more than a decade of declining cholera incidence, Vietnam faced an increase in cases of the diarrheal disease during 2007-2010. Risk factors for contracting cholera in Ben Tre province of Vietnam include drinking ...

Researchers have created a version of CRISPR-Cas that can be used to diagnose infections, such as Zika and dengue, with a high level of sensitivity.

There are many processes that take place in cells that are essential for life. Two of these, transcription and translation, allow the genetic information stored in DNA to be deciphered into the proteins that form all liv...

To function properly and propel the bacterium, the flagellum requires all of its components to fit together to exacting measurements. In a new study, researchers report the eludication of a mechanism that regulates the l...

A team of scientists has adapted a CRISPR protein that targets RNA (rather than DNA) as a rapid, inexpensive, highly sensitive diagnostic tool with the potential for a transformative effect on research and global public ...

Blackbirds do better when they nest near street lights, but all city birds seem to hate the noise

The most complex organ in humans is the brain. Due to its complexity, it is extremely difficult to do scientific experiments on it -- ones that could help us to understand neurodegenerative diseases like Parkinson's, for...

Thanks to drones, researchers could collect measurements from directly within a volcano's ash clouds, and gather visual and thermal images of the summit.

On the eve of the March for Science, organizers have started hinting about what they plan to do next.

Pooling many studies to get at the truth of which food is healthy or which pills work is being let down by bias and bad data, says John Ioannidis
