A new study puts into question conventional belief that the eyes communicate with the brain exclusively via one signaling pathway. Researchers have identified a subset of retinal neurons that sends inhibitory signals to ...

Lockdown measures and pandemic-related anxiety may be making you have more vivid dreams. Evidence suggests talking about them can help

A new genetics test for COVID-19 has been developed by an international team of researchers. The full genome sequencing test can not only provide accurate results in less than two minutes, but it can also extract intrica...

Many of the drugs and medicines that we rely on today are natural products taken from microbes like bacteria and fungi. Within these microbes, the drugs are made by tiny natural machines known as nonribosomal peptide syn...

A new study shows how virtual urgent care appointments increased by more than 600 percent, signaling a possible long-term shift in healthcare delivery.

The next time a tick feeds on you, researchers hope to make sure persistent arthritis caused by Lyme disease doesn't linger for a lifetime.

Stroke researchers have released a new report recommending the proper protocol for delivering lifesaving treatment to stroke patients during the COVID-19 pandemic.

Scientists have describe a class of cells that preferentially support latent infection by HIV. These cells are characterized by a surface protein called CD127 and are found in tissues such as lymph nodes, which are thoug...

New research has found that a subset of retinal neurons sends inhibitory signals to the brain. Before, researchers believed the eye only sends excitatory signals.

Each year thousands of patients face life-long losses in sensation and motor function from spinal cord injury and related conditions in which axons are badly damaged or severed. New research in mice shows, however, that ...

African naked mole-rats are sometimes referred to as animal superheroes. They resist cancer, tolerate pain, and live a remarkably long time. They're also known for their ability to handle high levels of carbon dioxide an...

Chemists have used ultrahigh resolution scanning tunneling microscopy to see the exact location of atoms and bonds within a molecule, and then employed these incredibly precise images to determine the interactions that b...

A new study has found that Irish patients admitted to hospital with severe COVID-19 infection are experiencing abnormal blood clotting that contributes to death in some patients.

Scientists tell the story of three 16th century African slaves identified from a mass burial site in Mexico City. Using a combination of genetic, osteological, and isotope analyses, the scientists determined from where i...

For the first time, people with arm amputations can experience sensations of touch in a mind-controlled arm prosthesis that they use in everyday life. A study reports on three Swedish patients who have lived, for several...

Two microscopic bubbles penetrate soft materials better than one, concludes a new study by engineers. Optical cavitation uses a laser to form bubbles in a liquid that expand rapidly then collapse. The new article shows t...

A recently completed study indicates that smoking by pregnant mothers caused roughly an 1.5-fold asthma risk in their offspring at the ages between 31 and 46.

Scientists have found a new method of reducing human body weight and fat mass using weighted vests. The new study indicates that there is something comparable to built-in bathroom scales that contributes to keeping our b...

A new mathematical model has been created to estimate the death toll linked to the COVID-19 pandemic in the United States and could be used around the world.

Early reports of COVID-19 symptoms and the compelling need to quickly identify treatment options and curb the growing number of critically ill patients have led to erroneous and potentially dangerous comparisons between ...

LIN28, a molecule that regulates cell growth could help in the treatment of spinal cord injury and optic nerve damage. When expressed above normal levels, the molecule fuels axon growth in mice with injury, enabling the ...

Older people who experience a worsening in insomnia symptoms are thirty times more likely to be diagnosed with major depression than those whose sleep patterns improved.
