Depressed and out of work? Therapy may help you find a job
If depression is making it more difficult for some unemployed people to land a job, one type of therapy may help, research suggests. In a new study, 41% of unemployed or underemployed people undergoing cognitive behavioral therapy (CBT) found a new job or went from part- to full-time work by the end of the 16-week treatment for depression.

Blink! The link between aerobic fitness and cognition
Researchers from the University of Tsukuba have found evidence that spontaneous eye blink activity, which reflects activity in the dopaminergic system, explains the connection between fitness and cognitive function. This is the first study to indicate that dopamine has an essential role in linking aerobic fitness and cognition. These findings open the door to new research regarding the mechanisms by which exercise improves brain function, and may lead to novel fitness strategies for enhancing cognition. (2021-02-03)

Scientists believe studies by colleagues are more prone to biases than their own studies
The properties of human mind affect the quality of scientific knowledge through the insertion of unconscious cognitive biases. Scientists from the University of Turku, Finland, have found that the current level of awareness about research biases is generally low among ecology scientists. Underestimation of the risks associated with unconscious cognitive biases prevents avoiding these risks in a scientist's own research. Due to unconscious origin of biases, it is impossible to combat them without external intervention. (2021-02-03)

New research investigates relationship between health literacy and self-care
It is important for patients to understand the necessary information for making health decisions, yet studies have shown that a large segment of the population lacks the health literacy to do so. Jessie Chin, School of Information Sciences at the University of Illinois Urbana-Champaign, and colleagues have investigated the relationship between health literacy and ''actionable memory,'' or memory for medication purposes, among diabetic patients. They report their results in the Journal of General Internal Medicine. (2021-02-02)

Researchers describe a molecular mechanism involved in the pathology's neurodegeneration
Protein alteration in the family of lamins causes several diseases, known as laminopathies, such as progeria or precocious ageing. A study in which UB researchers have taken part states that alterations in the levels of one of these proteins, lamin B1, contribute to the degeneration of neuronal populations in Huntington's disease. Caused by a mutation in the huntingtin gen, this pathology features involuntary movements, cognitive deficit and psychiatric disorders, and has no cure yet. (2021-02-01)

How the brain is programmed for computer programming?
Expert computer programmers show higher proficiency in certain behavioural and attention skills than their novice peers. To identify the responsible brain regions, scientists used fMRI to analyse the brain activities of 30 programmers of different skill level, finding that seven regions of the frontal, parietal and temporal cortices in expert programmers' brains are fine-tuned for programming. The findings could provide better methods and tools for everyone to learn programming. (2021-01-28)

Scientists identify individual neurons responsible for complex social reasoning in humans
Until now, how neurons represent another individual's belief and thoughts was unknown. Prior to undergoing planned neurosurgery, patients agreed to perform brief behavioral tasks as neuroscientists recorded the activity of individual neurons. The study revealed the basic cellular mechanism involved in a fundamental cognitive process vital to successful social interactions. Now researchers have a framework to investigate disorders in which social behavior is affected. (2021-01-27)

Confirmed improvement in first responders' brain health after shortened training protocol
People believe that they can't change their brains, or their brain health will decline as they age. But the SMART training protocol, created by researchers and clinicians at the Center for BrainHealth®, has demonstrated over the past two decades to improve cognitive function and psychological well-being in laboratory participants. Research suggests that SMART can even make long-lasting improvements to people's brain health when given outside of the lab in short, informal training sessions (2021-01-27)

Tungsten-substituted vanadium oxide breathes fresh air into catalyst technology
Tokyo, Japan - Researchers from Tokyo Metropolitan University have created a new tungsten-substituted vanadium oxide catalyst for breaking down harmful nitrogen oxides in industrial exhaust. Their new catalyst material works at lower temperatures and does not suffer major drops in performance when processing ''wet'' exhaust, resolving a major drawback in conventional vanadium oxide catalysts. They found that the unaggregated dispersal of atomic tungsten in the original crystal structure plays a key role in how it functions. (2021-01-26)
