A team of researchers at the Broad Institute of MIT and Harvard has developed a new technique for mapping cells. The approach, called DNA microscopy, shows how biomolecules such as DNA and RNA are organized in cells and tissues, revealing spatial and molecular information that is not easily accessible through other microscopy methods. DNA microscopy also does not require specialized equipment, enabling large numbers of samples to be processed simultaneously.
Berkeley -- The phrase "we're on the same wavelength" may be more than just a friendly saying: A new study by University of California, Berkeley, researchers shows that bats' brain activity is literally in sync when bats engage in social behaviors like grooming, fighting or sniffing each other.
"Whenever the bats were socially interacting, you could see these very robust correlations in brain activity," said Michael Yartsev, an assistant professor of neurobiology and bioengineering at UC Berkeley.
It's not an electron. But it sure does act like one.
Northwestern University researchers have made a strange and startling discovery that nanoparticles engineered with DNA in colloidal crystals -- when extremely small -- behave just like electrons. Not only has this finding upended the current, accepted notion of matter, it also opens the door for new possibilities in materials design.
Fast facts:
The liver is the only solid organ that can regenerate itself in mammals, but what confers this special property to the liver has not been uncovered, despite decades of research.
NYU Abu Dhabi researchers suggest that a novel mechanism driven by the epigenome promotes liver regeneration.
The epigenome refers to the code that packages the DNA so that some parts can be activated (i.e. genes) and some parts remain in dormant domains - these dormant parts largely contain remnants of old viruses or transposable elements.
Reduced blood flow to the brain associated with early Alzheimer's may be caused by the contraction of cells wrapped around blood vessels, according to a UCL-led study that opens up a new way to potentially treat the disease.
Blood provides the brain's energy supply in the form of glucose and oxygen. Earlier studies have suggested the first change in Alzheimer's disease is a decrease in cerebral blood flow.
In an advance for medical imaging, scientists from University of North Carolina Lineberger Comprehensive Cancer Center have discovered a method for creating radioactive tracers to better track pharmaceuticals in the body as well as image diseases, such as cancer, and other medical conditions.
UPTON, NY--Scientists studying plant biochemistry at the U.S. Department of Energy's Brookhaven National Laboratory recently made a surprising discovery: They found that a protein that turns on oil synthesis also activates a protein that puts the brakes on the same process. In a paper just published in the journal Plant Physiology, they describe how this seemingly paradoxical system keeps oil precursors perfectly balanced to meet plants' needs.
TORONTO, June 20, 2019 - There is no statistical evidence that global cigarette consumption has fallen as a result of the World Health Organization's Framework Convention on Tobacco Control, and in low- and middle-income countries it has actually increased, according to two studies led by global health researchers at York University.
WASHINGTON (June 20, 2019) -- Patients with psoriasis frequently use complementary or alternative therapies to treat their symptoms, according to survey results published by dermatologists from the George Washington University (GW) in the Journal of the American Academy of Dermatology.
It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells made are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.
LAWRENCE -- New research from the University of Kansas shows machine learning is capable of identifying insects that spread the incurable disease called Chagas with high precision, based on ordinary digital photos. The idea is to give public health officials where Chagas is prevalent a new tool to stem the spread of the disease and eventually to offer identification services directly to the general public.
PULLMAN, Wash. - A Washington State University research team has developed a drug delivery system using curcumin, the main ingredient in the spice turmeric, that successfully inhibits bone cancer cells while promoting growth of healthy bone cells.
The work could lead to better post-operative treatments for people with osteosarcoma, the second most prevalent cause of cancer death in children.
AUSTIN, Texas -- The leading cause of death in Texas is heart disease, according to the National Center for Health Statistics, accounting for more than 45,000 deaths statewide in 2017. A new wearable technology made from stretchy, lightweight material could make heart health monitoring easier and more accurate than existing electrocardiograph machines -- a technology that has changed little in almost a century.
MADISON, Wis. -- New research out of the University of Wisconsin-Madison Arboretum shows that temperatures of about 100 degrees Fahrenheit kill the cocoons of invasive jumping worms.
That's good news for ecologists and horticulturalists who are working to slow or stop the spread of the worms, which can damage the soils they invade. Common practices that raise the temperature sufficiently could limit the ability of worms to spread through paths such as compost or potted plants.
Montreal, June 20, 2019 - Our immune system is programmed to destroy cancer cells. Sometimes it has trouble slowing disease progression because it doesn't act quickly or strongly enough. In a study published in The Journal of Clinical Investigation, researchers from the University of Montreal Hospital Research Centre (CRCHUM) revealed the genetic signature of this failed immune response for the first time.
