Exposure to air pollution before and after birth may affect fundamental cognitive abilities

Posted by in categories: education, health, mathematics, neuroscience, sustainability

A growing body of research suggests that exposure to air pollution in the earliest stages of life is associated with negative effects on cognitive abilities. A new study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by “la Caixa”, has provided new data: exposure to particulate matter with a diameter of less than 2.5 μm (PM2.5) during pregnancy and the first years of life is associated with a reduction in fundamental cognitive abilities, such as working memory and executive attention.

The study, carried out as part of the BREATHE project, has been published in Environmental Health Perspectives. The objective was to build on the knowledge generated by earlier studies carried out by the same team, which found lower levels of cognitive development in children attending schools with higher levels of traffic-related air pollution.

The study included 2,221 children between 7 and 10 years of age attending schools in the city of Barcelona. The children’s cognitive abilities were assessed using various computerized tests. Exposure to air pollution at home during pregnancy and throughout childhood was estimated with a mathematical model using real measurements.

Hey, let’s fight global pandemics by maybe starting one… Say WHAT?

Posted by in categories: biotech/medical, government, health, policy

The US government quietly resumed funding experiments on the deadly H5N1 avian flu — research that makes the virus more easily transmissible to mammals.


The researchers say making new strains of the H5N1 flu virus in a secure lab can help them see what might happen naturally in the real world. Sounds logical, but many scientists oppose it because the facts show most biosafety labs aren’t really secure at all, and experts say the risks of a mutated virus escaping outweigh whatever public health benefit comes from creating them.

Amazon is reportedly working on an Alexa-powered wearable that reads human emotions

Posted by in categories: health, wearables

Amazon is reportedly developing a voice-activated wearable device that can recognize human emotions.

If successful, the health product could help the company improve its targeted advertisements and make better product recommendations, reports Bloomberg. The unnamed device could also advise humans on how to better interact with others.

A source showed Bloomberg internal Amazon documents that revealed a few details about the futuristic health and wellness product.

Possible link between infant gut microbiome and development of allergies

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

A team of researchers affiliated with several institutions in Korea and Australia have found a possible link between the gut microbiome in infants and development of allergies. In their paper published in the journal Science Advances, the group describes their study of a certain antibody response in young mice and what they found.

Food allergies have been widely reported in the past few years, particularly in children. Scientists have been taking a closer look at the causes of the seemingly sudden rise in the number of people who are allergic to certain foods. In this new effort, the researchers looked into the possibility of a connection between food allergies and the gut biome.

The research started after some noticed that raised in a sterile environment (who also had no gut microbiome) expressed higher levels of immunoglobulin E (IgE) when they matured enough to start eating solid food. Prior research has shown that IgE is a mediator that plays a role during an allergic response—when allergens are detected, IgEs send out signals alerting other parts of the immune system, which in turn release chemicals that result in inflammation, a major allergy symptom.

Bipolar disorder may be linked to Parkinson’s disease

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

People who have bipolar disorder may be more likely to later develop Parkinson’s disease than people who do not have bipolar disorder, according at a study published in the May 22, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.

“Previous studies have shown a relationship between depression and Parkinson’s disease, but few studies have looked at whether there is a relationship between and Parkinson’s,” said study author Mu-Hong Chen, MD, Ph.D., of Taipei Veterans General Hospital in Taiwan.

For the study, researchers examined a national Taiwanese health database for people were diagnosed with disorder between 2001 and 2009 and who had no history of Parkinson’s disease, for a total of 56,340 people. They were matched with 225,360 people of the same age, sex and other factors who had never been diagnosed with bipolar disorder or Parkinson’s disease as a control group. Then the two groups were followed until the end of 2011.

Why lack of sleep is bad for your heart

Posted by in categories: biotech/medical, health

A new University of Colorado Boulder study, published in the journal Experimental Physiology, helps explain why.

It found that people who sleep fewer than 7 hours per night have lower blood levels of three physiological regulators, or microRNAs, which influence gene expression and play a key role in maintaining vascular health.

The findings could potentially lead to new, non-invasive tests for sleep deprived patients concerned about their health, the authors said.

Ebola confirmed in a city of more than 1 million in Congo

Posted by in categories: biotech/medical, health

JOHANNESBURG (AP) — The global health community gulped Thursday with the announcement that a case of Ebola had been confirmed in a city of more than 1 million in Congo, bringing the latest outbreak of the often deadly hemorrhagic fever out of remote rural areas. “Confirmation of urban #Ebola in #DRC is a game changer in this outbreak – the challenge just got much much tougher,” the World Health Organization’s emergencies chief, Dr. Peter Salama, said on Twitter. Here’s a look at the outbreak.

What is Ebola?

Ebola is a virus that without preventive measures can spread quickly between people and is fatal in up to 90 percent of cases. The symptoms include fever, vomiting, diarrhea, muscle pain and at times internal and external bleeding. Symptoms can start to occur between two and 21 days from infection, according to WHO.
