Immune system mediated injury rather than the virus entering and killing brain cells may explain why people experience long-term consequences associated with COVID-19 infection.

A camera usually requires a lens system to capture a focused image, and the lensed camera has been the dominant imaging solution for centuries. A lensed camera requires a complex lens system to achieve high-quality, brig...

From helping to improve attention and staving off cognitive decline, to improving immune system function, researchers explore the many health benefits tea has to offer.

New findings reveal how anesthesia-induced unconsciousness differs from normal sleep in relation to delta wave activity in the brain.

The optimal amount of sleep for middle-aged and older adults is seven hours per night. Sleeping too little, or too much, was associated with poor cognitive performance and mental health, researchers say.

Researchers at UC San Diego School of Medicine report that high-frequency spinal cord stimulation proved more effective at improving perceived pain reduction than low-frequency SCS in patients studied, and that there was...

Researchers have identified a specific neural circuit and neuropeptide responsible for relaying the sensation of a pleasant touch from the skin to the brain.

As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment. To do so, plants have evolved distinct molecular mechanisms to sense and respond to the environment a...

Lawrence Livermore National Laboratory (LLNL) researchers have developed a new all-optical ultrasound technique capable of performing on-demand characterization of melt tracks and detecting formation of defects in a popu...

After examining data from more than 18,000 dogs, researchers have reached a clear conclusion: breed doesn't explain why dogs behave the way they do

Researchers have identified a specific neuropeptide and a neural circuit that transmit pleasant touch from the skin to the brain. The findings eventually may help scientists better understand and treat disorders characte...

Scientists have been able to demonstrate that nerve signals are exchanged between arteries and the brain in atherosclerosis.

A new analysis of data from the Veterans Affairs Million Veteran Program has uncovered genetic links between COVID-19 severity and certain medical conditions that are known risk factors for severe COVID-19.

Harnessing the power that makes the sun and stars shine could be made easier by powerful magnets with straighter shapes than have been made before. Researchers linked to the U.S. Department of Energy's (DOE) Princeton Pl...

Time'correlated single'photon counting (TCSPC) technique is a powerful way to measure the weak light signals. The basic principle behind TCSPC is the photoelectric effect in which an electrical charge is released by abso...

As race season approaches, many runners have the same goal: go faster. But researchers now show that speeding up might require defying our natural biology. By combining data from runners monitored in a lab along with 37,...

Scientists tracked the rise and fall of SARS-CoV-2 in the saliva and nasal cavities of people newly infected with the virus. The study was the first to follow acute COVID-19 infections over time through repeated sampling...

Seven hours is the ideal amount of sleep for people in their middle age and upwards, with too little or too much little sleep associated with poorer cognitive performance and mental health, say researchers.

A new study captures the current understanding of the connection between the gut microbiome and therapeutic response to immunotherapy, chemotherapy, cancer surgery and more, pointing to ways that the microbiome could be ...

Researchers report insights into the mechanism of how human NANOG facilitates the activation of cell pluripotency.

Investigators have devised a novel method for improving CAR T therapy through a drug combination and cellular engineering that improves the strength and durability of the tumor-killing effect of a CAR T directed against ...

Researchers have developed a new way to apply antireflective (AR) coatings to 3D printed multi-lens systems as small as 600 microns in diameter. Because these coatings help minimize light losses due to reflection, they a...
