Fragile X finding shows normal neurons that interact poorly

Thu, 18 Jan 18 00:03:40 -0800

Neurons in mice afflicted with the genetic defect that causes Fragile X syndrome (FXS) appear similar to those in healthy mice, but these neurons fail to interact normally, resulting in the long-known cognitive impairments, shows a new study by a team of neuroscientists.

Controlling nanoscale DNA robots from the macroscale

Thu, 18 Jan 18 00:08:50 -0800

By powering a DNA nanorobotic arm with electric fields, scientists have achieved precise nano-scale movement that is at least five orders of magnitude faster than previously reported for DNA-driven robotic systems.

Study finds shift in patterns of glutamate and GABA in visuospatial working memory network

Thu, 18 Jan 18 00:12:50 -0800

A new study in Biological Psychiatry has characterized the patterns of brain neurotransmitters glutamate and GABA in a network of regions that temporarily maintain and process visual information about the location of objects in space, a cognitive ability referred to as visuospatial working memory. The study reports that the patterns are altered in people with schizophrenia, suggesting a potential explanation for the impairments in visuospatial working memory that characterize people with the disorder.

Prebiotics in infant formula could improve learning and memory and alter brain chemistry

Wed, 17 Jan 18 00:14:40 -0800

Among other benefits, breast milk contains natural sources of prebiotics: small, indigestible fiber molecules that promote the growth of good bacteria in the baby's gut. Yet for many families, breastfeeding is difficult or impossible. Fortunately, modern infant formulas are getting closer to the real thing with the help of University of Illinois researchers.

Ultra-thin memory storage device paves way for more powerful computing

Wed, 17 Jan 18 00:15:40 -0800

A team of electrical engineers at The University of Texas at Austin, in collaboration with Peking University scientists, has developed the thinnest memory storage device with dense memory capacity, paving the way for faster, smaller and smarter computer chips for everything from consumer electronics to big data to brain-inspired computing.

How your brain remembers what you had for dinner last night

Wed, 17 Jan 18 00:08:20 -0800

Confirming earlier computational models, researchers at University of California San Diego and UC San Diego School of Medicine, with colleagues in Arizona and Louisiana, report that episodic memories are encoded in the hippocampus of the human brain by distinct, sparse sets of neurons.

The brain's creativity controls

Wed, 17 Jan 18 00:08:40 -0800

Scientists studying brain scans of people who were asked to come up with inventive uses for everyday objects found a specific pattern of connectivity that correlated with the most creative responses. Researchers were then able to use that pattern to predict how creative other people's responses would be based on their connections in this network.

The innate immune system can also be trained

Tue, 16 Jan 18 00:06:10 -0800

Researchers of the Faculty of Medicine Carl Gustav Carus of the TU Dresden identified that precursors of immune cells in the bone marrow can be trained to respond better to future challenges.

Can training improve memory, thinking abilities in older adults with cognitive impairment?

Tue, 16 Jan 18 00:01:10 -0800

A new, first-of-its-kind study was published in the Journal of the American Geriatrics Society by scientists from research centers in Montreal and Quebec City, Canada. They designed a study to learn whether cognitive training, a medication-free treatment, could improve MCI. Studies show that activities that stimulate your brain, such as cognitive training, can protect against a decline in your mental abilities. Even older adults who have MCI can still learn and use new mental skills.

Memory loss from West Nile virus may be preventable

Tue, 16 Jan 18 00:00:20 -0800

More than 10,000 people in the United States are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. Now, a new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain's ability to repair damaged neurons and grow new ones. When the inflammation was reduced by treatment with an arthritis drug, the animals' ability to learn and remember remained sharp after West Nile disease.

Epigenetics study helps focus search for autism risk factors

Tue, 16 Jan 18 00:03:50 -0800

Researchers at Washington State University and elsewhere have associated more than 2,000 DNA regions that control gene expression and are strongly associated with autism. Further study within one of those regions revealed a genetic mutation that is associated with increased risk of developing autism.

Clockwork under the microscope

Tue, 16 Jan 18 00:05:40 -0800

Circadian clocks regulate the behaviour of all living things. Scientists from the University of Würzburg have now taken a closer look at the clock's anatomical structures and molecular processes in the honeybee.

Long-lasting adaptations of the innate immune system through the bone marrow

Thu, 11 Jan 18 00:10:50 -0800

The immune system not only detects and destroys pathogens such as microbes but also plays a role in the onset of diseases such as arteriosclerosis. Scientists from Radboud university medical center, Bonn, Dresden and Pennsylvania, studied a new mechanism that regulates the immune system's functioning. They discovered that cholesterol inhibitors may prevent infections, that a high-fat Western diet can have a long-lasting effect on our immunity and that even our stem cells can be disrupted.

Re-programming innate immune cells to fight tuberculosis

Thu, 11 Jan 18 00:09:50 -0800

Tuberculosis (TB), an infectious disease which attacks the lungs, claims someone's life every 20 seconds and 1.5 million lives worldwide every year. A cure has eluded scientists for more than a century but, now, a Montreal team of researchers may have discovered a new weapon to combat this global killer. The team is re-programing - or 'training' - immune cells to kill TB. These groundbreaking findings are published online today in the journal Cell.

Thu, 04 Jan 18 00:08:00 -0800

Recent advances in brain imaging have enabled scientists to show for the first time that a key protein which causes nerve cell death spreads throughout the brain in Alzheimer's disease -- and hence that blocking its spread may prevent the disease from taking hold.

Researchers identify genetic factors that contribute to Alzheimer's disease

Wed, 03 Jan 18 00:15:00 -0800

Researchers have identified several new genes responsible for Alzheimer's disease (AD) including those leading to functional and structural changes in the brain and elevated levels of AD proteins in cerebrospinal fluid (CSF).

Diabetes drug 'significantly reverses memory loss' in mice with Alzheimer's

Sun, 31 Dec 17 00:02:10 -0800

A drug developed for diabetes could be used to treat Alzheimer's after scientists found it 'significantly reversed memory loss' in mice through a triple method of action. This is the first time that a triple receptor drug has been used which acts in multiple ways to protect the brain from degeneration. It combines three growth factors. Problems with growth factor signalling have been shown to be impaired in the brains of Alzheimer's patients.

Guideline: Exercise may improve thinking ability and memory
Exercising twice a week may improve thinking ability and memory in people with mild cognitive impairment (MCI), according to a guideline released by the American Academy of Neurology. The recommendation is an update to the AAN's previous guideline on mild cognitive impairment and is published in the Dec. 27, 2017, online issue of Neurology
