Rewiring the Brain: Poverty Linked With Neurological Changes That Affect Behavior, Illness, and Development

Posted by in categories: education, habitats, neuroscience

What influences mental health, academic achievement, and cognitive growth? A recent review published in De Gruyter’s Reviews in the Neurosciences indicates that poverty and low socioeconomic status (SES) are significant contributing factors. While previous research has explored the individual impacts of poverty on the brain and behavior, this review introduces the first integrated framework. It synthesizes evidence from various studies to directly connect brain alterations caused by low SES with behavioral, pathological, and developmental outcomes.

SES refers to the social standing of an individual or family, and involves factors such as wealth, occupation, educational attainment, and living conditions. As well as affecting day-to-day life, perhaps surprisingly SES can also have far-reaching consequences for our brains that begin in childhood and persist into adulthood.

So, how can poverty and low SES change the brain? The review examines the negative effects of poor nutrition, chronic stress, and environmental hazards (such as pollution and inadequate housing conditions), which are more likely to affect low-SES families. These factors can impair the brain development of children, which in turn can influence their language skills, educational attainment, and risk of psychiatric illness.

Redwire announces second VLEO satellite platform

Posted by in categories: business, satellites

WASHINGTON — Redwire Space is doubling down on interest in the emerging market for very low Earth orbit (VLEO) satellites by offering a second spacecraft platform from its European subsidiary.

In a May 9 earnings call, Redwire announced a VLEO satellite platform called Phantom, developed by the company’s European business unit in Belgium. Phantom is being developed for the European Space Agency’s Skimsat mission, on which Redwire is partnered with Thales Alenia Space, and is now being offered for European and international customers.

Phantom joins SabreSat, a VLEO satellite Redwire announced in its previous earnings call in March that is being developed by the company in the United States. The two designs use different technologies.

Alarming Findings: New Study Reveals Childhood Abuse Drives 40% of Mental Health Conditions

Posted by in categories: biotech/medical, health, neuroscience

A study focusing on childhood maltreatment in Australia has uncovered its alarming impact, estimating it causes up to 40 percent of common, life-long mental health conditions.

The mental health conditions examined were anxiety, depression, harmful alcohol and drug use, self-harm, and suicide attempts. Childhood maltreatment is classified as physical, sexual, and emotional abuse, and emotional or physical neglect before the age of 18. Childhood maltreatment was found to account for 41 percent of suicide attempts in Australia, 35 percent for cases of self-harm, and 21 percent for depression.

The analysis, published in JAMA Psychiatry is the first study to provide estimates of the proportion of mental health conditions in Australia that arise from childhood maltreatment. The researchers said the results are a wake-up call for childhood abuse and neglect to be treated as a national public health priority.

Solving a Long-Standing Marine Mystery: New Insights Into Rhizobia-Diatom Symbiosis

Posted by in categories: biological, food

A groundbreaking study reveals that Rhizobia bacteria can fix nitrogen in partnership with marine diatoms, a discovery that could have significant implications for agriculture and marine ecosystems.

Nitrogen is an essential component of all living organisms. It is also the key element controlling the growth of crops on land, as well as the microscopic oceanic plants that produce half the oxygen on our planet.

Atmospheric nitrogen gas is by far the largest pool of nitrogen, but plants cannot transform it into a usable form. Instead, crop plants like soybeans, peas and alfalfa (collectively known as legumes) have acquired Rhizobial bacterial partners that “fix” atmospheric nitrogen into ammonium. This partnership makes legumes one of the most important sources of proteins in food production.

Blurred Light Harnessed to 3D Print High Quality Lenses

Posted by in category: 3D printing

New 3D printing method produces commercial grade microlenses with smooth surfaces, which could advance optical device design.

Researchers in Canada have developed a new 3D printing method called blurred tomography that can rapidly produce microlenses with commercial-level optical quality. The new method may make it easier and faster to design and fabricate a variety of optical devices.

“We purposely added optical blurring to the beams of light used for this 3D printing method to manufacture precision optical components,” said Daniel Webber from the National Research Council of Canada. “This enables production of optically smooth surfaces.”

High school student helps transform ‘crazy idea’ into a model that can predict neurotransmitters

Posted by in category: education

Like many good ideas in science, it started with a walk in the woods. During a stroll through the Berlin Botanic Garden in 2019, HHMI Janelia Research Campus Group Leader Jan Funke and some of his scientific colleagues started chatting about a familiar topic: How to get more information out of insect connectomes.
