How Human Brains could be Hacked
Like computers, human brains may be vulnerable to hackers. Technology is already allowing scientists to read people's thoughts and even plant new ones in the brain. The latest episode of the Science Channel's "Through the Wormhole," hosted by Morgan Freeman, explores the potential — and dangers — of hacking the mind. The episode premieres tonight (July 3) at 10 p.m. ET. "We live a ...

Brain Imaging in Zebrafish
An adult human brain contains approximately 86 billion neurons, along with about 85 billion non-neuronal cells. All those cells work together to manage motor control, sensory perception, heart rate, breathing, and more. While the human brain is extremely complex, with the ability to process language, it is not totally unique. Most vertebrate brains are quite similar; they all need similar ...

The effects of antidepressants appear to be rapid and at environmentally relevant concentrations
The effects of antidepressants on wildlife are currently raising some concern due to an increased number of publications indicating biological effects at environmentally relevant concentrations (<100ng/L). These results have been met with some scepticism due to the higher concentrations required to detect effects in some species and the perceived slowness to therapeutic effects recorded in ...

Neuroscientific evidence: a criminal justice dream, or an adversarial nightmare?
This exploratory paper seeks to examine the use of neuroscientific evidence in the criminal trial process. Such evidence is not currently employed in the pre–trial or trial stages in England and Wales. However, the first use of polygraph lie detectors during the pre–charge process has recently been trailed by Hertfordshire Police. More advanced techniques such as the BEOS test and the use of fMRI ...

The effects of bupropion on hybrid striped bass brain chemistry and predatory behavior
Increased use of antidepressants has led to an increase in their detection in final treated wastewater effluents and receiving streams. Antidepressants are intended to modify human behavior by altering brain chemistry, and due to the high functional conservation of the receptor targets of antidepressant target receptors in vertebrates, aquatic organisms may be at risk. The antidepressant ...

New Approach to Successfully Purify and Characterize Human Neural Stem Cells
Human brain has approximately 171 billion cells, of which slightly more than half (approximately 86 billion) are nerve cells. These 86 billion nerve cells are a diverse cell population with hundreds of specialized types and functions, but all originate from three neural cell lineages--neurons, oligodendrocytes, and astrocytes. All three cell lineages originate from a pool of neural stem and ...

The Salience Network
What is the salience brain network? The salience network (SN) is “the moderator.” As your mind’s personal moderator, the salience network constantly monitors the external world and carefully decides how other brain networks react to new information and stimuli. The SN moderates switching between the internal and external processing1 of the brain’s two main ...

Glucose metabolism: key to neurodegenerative diseases
Previously, it was thought that glial cells, which support neuronal activity, metabolize most of the glucose in the brain. However, by using induced pluripotent stem cells, the researchers found that neurons were able to take up glucose and process it into smaller metabolites. In mice, normal function of neurons depends on glycolysis. The findings could help develop new treatments for ...

Spatial profiling of chromatin accessibility in mouse and human tissues
Abstract Cellular function in tissue is dependent on the local environment, requiring new methods for spatial mapping of biomolecules and cells in the tissue context1. The emergence of spatial transcriptomics has enabled genome-scale gene expression mapping2,3,4,5, but the ability to capture spatial epigenetic information of tissue at the cellular level and genome scale is lacking. Here we ...

Why corrections officers need to pay extra attention to incoming mail
Contraband smuggling in correctional facilities was already on the rise before the coronavirus pandemic, and would-be smugglers continue to develop new means of concealment. This evolving challenge to safety inside jails and prisons has intensified in the past year, and due to the lockdowns to combat the spread of the COVID-19 virus, postal mail has become a favored conduit for contraband drugs. ...

Nipah virus glycoprotein structure suggests therapeutic strategies
Recent molecular discoveries have provided new details on how Nipah and Hendra viruses attack cells, and the immune responses that fight back against this attack. The findings point to a multi-pronged strategy for preventing and treating these deadly diseases. The study was published in Science recently. Both Nipah virus and Hendra virus are carried by indigenous bats in some parts of the ...

What are brain networks?
There is no such thing as unimportant, or non-eloquent, brain. For decades, neuroscientists and clinicians have studied the brain attempting to pinpoint the regions that control specific functions. This is the age old question of ‘What part of the brain is responsible for ___?’ For clinicians, this assists in determining where the source of certain disorders may originate and ...

How Sleep Deprivation Can Lead to Weight Gain
Sleep is an important factor to help maintain health and well-being. It’s recommended that an adult should get at least 7 hours of sleep a night. Getting a good night’s sleep has many benefits such as better memory, reduced stress levels and lowers the risk of heart disease. On the flip side, not getting enough sleep regularly can have serious repercussions such as a weaker immune ...

The Importance of Water for the Body - Puroxi
Common Contaminants in Your Tap Water. Antibiotic Use Increased In 2010 Food Animal Production Sales of antibiotics intended for domestic food animals increased from 2009 to 2010, according to new data released by the U.S. Food and Drug Administration. The Pew Health Group analyzed the numbers in the report, the second-ever issued by FDA, which showed a boost of 6.7 percent, from 28.8 million ...

Diaspora and development: lessons from Somaliland
The success of the University of Hargeisa in Somaliland demonstrates how the flow of skilled migrants from the developing to the developed world – once viewed merely as brain 'drain' – may in fact be more accurately described as an imperfect circular flow of skilled workers, knowledge, finance, and development. The skilled Diaspora can invoke its capabilities, networks, and access to financial ...

Nature: Structure-based classification of tauopathies
Abnormal accumulation of misfolded tau in filaments is characteristic of many neurodegenerative diseases—precisely for this reason, these neurodegenerative diseases are collectively referred to as tauopathy. The Michel Goedert team and the Sjors Scheres team at the Molecular Biology Laboratory of the Medical Research Council in Cambridge, UK, witnessed the use of cryo-EM to dissect tau ...

What are Strongyloides?
Strongyloides is an opportunistic pathogenic parasitic nematode. Adults parasitize in the small intestine of cats, dogs and humans. The larvae can invade lung, brain, liver, kidney and other tissues and organs, causing strongyloidiasis. The disease is mainly prevalent in warm and humid tropical and subtropical regions. In recent years, due to the continuous increase of HIV/AIDS infection rate in ...
