(College of Engineering, Carnegie Mellon University) Carnegie Mellon University's Maarten de Boer and Gianluca Piazza are developing reliable, mechanical switches the size of a DNA molecule, thanks to a $2M LEAP-HI grant...

Combining brain imaging data with a new machine learning algorithm, researchers can accurately predict the risk and determine a diagnosis for Alzheimer's disease.

Researchers used the light reflecting off the wrapper to build an image of its surroundings --

The COVID-19 pandemic has unmasked longstanding racial and ethnic health-related disparities, according to a new article. The essay notes higher rates of COVID-19 hospitalizations, deaths or positive cases among blacks, ...

Most newly discharged patients who recently recovered from COVID-19 produce virus-specific antibodies and T cells, a new study suggests, but the responses of different patients are not all the same. While the 14 patients...

The immune responses of a female mouse before pregnancy can predict how likely her offspring are to have behavioral deficits if the immune system is activated during pregnancy. The findings could help resolve what role s...

Korean researchers have screened 48 FDA-approved drugs against SARS-CoV-2, and found that two, that are already FDA-approved for other illnesses, seem promising. The FDA approval for other uses would greatly reduce the t...

Overuse of antibiotics, high animal numbers and low genetic diversity from intensive farming increase the risk of animal pathogens transferring to humans.

For the first time, physician-scientists have identified two clusters of depressive symptoms that responded to two distinct neuroanatomical treatment targets in patients who underwent transcranial magnetic brain stimulat...

Twice as many women who experienced a hypertensive disorder during any of their pregnancies were at increased risk of developing heart or kidney diseases earlier in life based on incidence per woman versus per pregnancy,...

Researchers are driving advances in human genome assembly to make the process better, faster, and cheaper. Researchers plan to leverage these innovations to create a reference genome more representative of human diversit...

Activating the G protein-coupled estrogen receptor (GPER) -- a receptor found on the surface of many normal and cancer tissues -- has been shown to stop pancreatic cancer from growing, but may also make tumors more visib...

Fecal transplants are currently used to treat certain types of antibiotic-resistant diarrhea and has also been attempted to treat e.g. inflammatory bowel disease. A new study suggests that transplanted intestinal content...

Football-shaped microscale cages have been created using special laser technologies. Using sound waves as tweezers, living neurons can be placed inside these cages to study how nerve connections are being formed.

When an emergency dispatcher calls for a helicopter to fly a critically ill patient to a hospital, they don't have time to check whether they take the patient's insurance. But after those patients land, 72% of them could...

Scientists have discovered how the materials used in medical implants like artificial joints can be adapted to control the immune response to them and reduce the risk of rejection.

A study to help determine the rate of novel coronavirus infection in children and their family members in the United States has begun enrolling participants. The study also will help determine what percentage of children...

Wide-scale use of insecticide-treated bed nets has led to substantial declines in global incidences of malaria in recent years. As a result, mosquitoes have been shifting their biting times to earlier in the evening and ...

A viral spike protein mediates entry of SARS-CoV-2 into host cells and harbors an unusual activation sequence. This sequence is cleaved by the cellular enzyme furin and the cleavage is important for the infection of lung...

Researchers have found that the coronavirus SARS-CoV-2, which causes COVID-19, can infect the cells of the intestine and multiply there. Using state-of-the-art cell culture models of the human intestine, the researchers ...

As more states are requiring people to wear face masks in public to prevent the spread of COVID-19, researchers investigate the best materials people can use to create their masks at home. A single layer of T-shirt fabri...

New microscopy technology images the position of biomolecules with precision down to a few nanometers inside whole cells and tissues.
