Now a new study has found that people with cerebral small vessel disease who have blood-brain barrier leakage had more brain tissue damage over two years than people with less blood-brain barrier leakage.

Pumpkin growers dread the tiny tan scabs that form on their fruit, each lesion a telltale sign of bacterial spot disease. The specks don't just mar the fruit's flesh, they provide entry points for rot-inducing fungus and other pathogens that can destroy pumpkins and other cucurbits from the inside out. Either way, farmers pay the price, with marketable yields reduced by as much as 90%.
When clinical trials were conducted to determine the immunogenicity -- the ability to elicit an immune response -- for the first two vaccines marshaled against SARS-CoV-2the virus that causes COVID-19, one group was not among those included: people who have received solid organ transplants and others (such as those with autoimmune disorders) who are immunocompromised.
Archaeologists examined the remains of houses in ancient Maya cities and compared them with other Mesoamerican societies; they found that the societies with the most wealth inequality were also the ones that had governments that concentrated power with a smaller number of people.
Reasons for more than a decade of black cherry regeneration decline in the Allegheny Hardwood Regions are not well-understood; a team of scientists looked at five leading hypotheses; they found that the most likely factors are pathogens and reduced nitrogen availability, and that black cherry may actually be a story of change on a much bigger scale.
Scientists report a novel noninvasive treatment for brain disorders based on breakthroughs in both optics and genetics. It involves stimulation of neurons by means of radioluminescent nanoparticles injected into the brain and exposed to X-rays.
A new study projecting the amount of heat stress residents of the region will experience in the future finds with 2 degrees Celsius of warming, the population's exposure to heat stress will nearly triple.
An international team has produced the first high-resolution 3D image of the sarcomere, the basic contractile unit of skeletal and heart muscle cells, by using electron cryo-tomography. Electron cryo-tomography capability of imaging structures directly in frozen muscle cells could translate into future medical treatments for muscle diseases and a better understanding of the aging process.
Researchers have studied for the first time how chemical reactions in clouds can influence the global climate. They found that isoprene, the dominant non-methane organic compound emitted into the atmosphere, can strongly contribute to the formation of organic aerosols in clouds.
The wrong type of earthquake in an area where there should not have been an earthquake led researchers to uncover the cause for this unexpected strike-slip earthquake -- where two pieces of crust slide past each other on a fault -- in places where subduction zone earthquakes -- one geologic plate slipping beneath another -- are common.
An international team of scientists presents an analysis of sediments from a cave in northeast Greenland, that cover a time period between about 588,000 to 549,000 years ago. This interval was warmer and wetter than today, the cave deposits provide an outlook in a possible future warmer world due to climate change.
Researchers find that the earliest bacteria had the tools to perform a crucial step in photosynthesis, changing how we think life evolved on Earth.
Researchers discovered that patient survival from sepsis is associated with higher platelet counts, and identified two currently available drugs that protect these blood cells and improve survival in mice with sepsis.
The secret to building superconducting quantum computers with massive processing power may be an ordinary telecommunications technology - optical fiber. Physicists have measured and controlled a superconducting quantum bit (qubit) using light-conducting fiber instead of metal electrical wires, paving the way to packing a million qubits into a quantum computer rather than just a few thousand.
The heart of any computer, its central processing unit, is built using semiconductor technology, which is capable of putting billions of transistors onto a single chip. Now, researchers have shown that this technology can be used to build a two-dimensional array of qubits to function as a quantum processor. Their work is a crucial milestone for scalable quantum technology.
Over the past decades, the increased use of chemicals in many areas led to environmental pollution - of water, soil and also wildlife. In addition to plant protection substances and human and veterinary medical drugs, rodenticides have had toxic effects on wildlife.
Eating just one cup of leafy green vegetables every day could boost muscle function, according to new research. The study found that people who consumed a nitrate-rich diet, predominantly from vegetables, had significantly better muscle function of their lower limbs.
Rich false memories of autobiographical events can be planted - and then reversed, a new article has found.
Living tissue can heal itself from many injuries, but giving similar abilities to artificial systems, such as robots, has been extremely challenging. Now, researchers have developed small, swimming robots that can magnetically heal themselves on-the-fly after breaking into two or three pieces. The strategy could someday be used to make hardier devices for environmental or industrial clean up, the...
The process of fabricating materials is complicated, time-consuming and costly. Too much of one material, or too little, can create problems with the product, forcing the design process to begin again. Advancements in the design process are needed to reduce the cost and time it takes to produce materials with targeted properties.
To help environmental agencies battle the toxic threats posed by landfills, researchers have developed a system that ranks the toxins present in a landfill by order of toxicity and quantity, allowing agencies to create more specific and efficient plans to combat leachate.
Researchers have discovered BASP-1, a novel biomarker of adult human neural stem cells. With this newly discovered biomarker, scientists can better understand the relevance and intricate mechanisms of neurogenesis, which may lead to new future therapeutic approaches to treat and manage neurological and neuropsychiatric disorders associated with diminished neurogenesis.
Lung tumors are home to immune cells that affect their growth and resistance to treatment. Looking at neutrophils, scientists led by EPFL have discovered that the key might lie in the cells' ability to metabolize glucose, opening an entirely new target for improving radiotherapy.
Sickle cell disease is the most prevalent inherited blood disorder in the world, affecting 70,000 to 100,000 Americans. However, it is considered an orphan disease, meaning it impacts less than 200,000 people nationally, and is therefore underrepresented in therapeutic research.
A new study is the first to identify how human brains grow much larger, with three times as many neurons, compared with chimpanzee and gorilla brains. The study identified a key molecular switch that can make ape brain organoids grow more like human organoids, and vice versa.
