New research from the Center for BrainHealth at The University of Texas at Dallas shows that certain cognitive training exercises can help reduce depression and improve brain health in individuals years after they have suffered a traumatic brain injury (TBI).
RIVERSIDE, Calif. -- Drugs available to treat multiple sclerosis, a leading cause of neurological disability affecting roughly 2.3 million people worldwide, alter the body's immune system to reduce disease symptoms and disability.
They do not induce, however, repair of damaged axons, the long threadlike parts of nerve cells that conduct impulses between cells or restore myelin, the protective sheath that surrounds the axons of neurons essential for the proper functioning of the brain and spinal cord.
The concept of survival of the fittest most often applies to the competition that occurs within and between animal species, but evolutionary pressures can be found elsewhere--even in a cancerous tumor.
Cancer researchers have come to understand tumors not as lumps of identical cells, but rather as diverse, dynamic populations unto themselves. And, like individuals within animal populations, cells within tumors compete with one another, some thriving, some failing.
JUPITER, FL--May 29, 2018--As scientists gain insights into which genes drive diseases, they are pursuing the next logical question: Can gene editing technologies be developed to treat or even cure those diseases? Much of that effort has focused on developing technologies such as CRISPR-Cas9, a protein-based system.
At The Scripps Research Institute campus in Florida, chemist Matthew D. Disney, PhD, has taken a different approach, developing a small-molecule-based tool that acts on RNA to selectively delete certain gene products.
Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
Experts at recognizing faces often play a crucial role in criminal cases. A photo from a security camera can mean prison or freedom for a defendant--and testimony from highly trained forensic face examiners informs the jury whether that image actually depicts the accused. Just how good are facial recognition experts? Would artificial intelligence help?
Limiting global warming to 1.5°C could avoid around 3.3 million cases of dengue fever per year in Latin America and the Caribbean alone - according to new research from the University of East Anglia (UEA).
A new report published today in the Proceedings of the National Academy of Sciences (PNAS) reveals that limiting warming to the goal of the UN Paris Agreement would also stop dengue spreading to areas where incidence is currently low.
Breakthrough lab-on-a-chip technology that reveals how human cells communicate could lead to new treatments for cancer and autoimmune disorders.
Developed by an Australian-Swiss research team, the technology offers researchers unprecedented insights into how individual cells behave - something that scientists are discovering is far more complex than previously thought.
"Dolphin liberation in South Korea has raised awareness towards the welfare of marine animals and has resulted in the strengthening of animal protection policies and the level of welfare."
An engineering student, affiliated with UNIST has recently carried out a scientific investigation on dolphin liberation in South Korea. The paper presents the overall analysis of the social impact of the first case of dolphin rehabilitation in Asia, which occurred in 2013.
As the old adage goes, 'two heads are better than one'. With the development of new technologies and increasingly specialist expertise, ground-breaking science needs to be a team effort.
But it isn't always easy for researchers to work together. Finding the right people to collaborate with can be tricky, especially when some are understandably protective of their ideas.
Then there is the practical challenge of meeting up, exchanging ideas and carrying out the research, miles - and even time zones - apart.
Exchange of material and information at the level of individual cells requires transport and signalling at level of the plasma membrane enclosing the cell. Studying mechanisms at such tiny dimensions presents researchers with enormous challenges - for example, when they want to find out how an important component of the membrane - cholesterol - behaves and is distributed. So far, cholesterol can only be labelled to a very limited extent with fluorescent dyes, which can be visualized under the microscope without damaging the membrane.
The world of reptiles may well include creatures that are more spectacular than the Gehyra variegata, but nevertheless, this small nocturnal gecko has managed to make a couple of fascinating new contributions to the discussion about the ecological consequences of climate change.
PHILADELPHIA -- Mutations to the protein tau, commonly associated with neurodegenerative disorders, may serve as a novel risk factor for cancer, according to results published in Cancer Research, a journal of the American Association for Cancer Research.
WEST LAFAYETTE, Ind. -- People looking to manage their weight with strength-training and protein supplements should consume their supplements during a meal, according to a research review by nutrition experts at Purdue University.
"It may matter when you take your supplements in relation to when you eat meals, so people who consume protein supplements in between meals as snacks may be less likely to be successful in managing their body weight," said Wayne Campbell, professor of nutrition science and senior author on the study.
Orlando, FL - Understanding the microscopic structure of a material is key to understanding how it functions and its functional properties. Advances in fields like materials science have increasingly pushed abilities to determine these features to even higher resolutions. One technique for imaging at nanoscale resolution, transmission electron microscopy (TEM), is one example of promising technology in this area.
