A New Treatment Can Relieve Food Allergies, But Few Doctors Offer It

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

Because there’s not yet an FDA-approved version of this treatment, most medical providers don’t yet offer it. So most patients can get it only by enrolling in research studies, of which there have been dozens in recent years.


Patients Find Relief For Food Allergies In Oral Immunotherapy Treatment : Shots — Health News Many parents of kids with life-threatening food allergies live with fear, EpiPen in hand. Some are trying oral immunotherapy, a treatment that can help patients build tolerance to foods like peanuts.

Goodyear’s “living” car tyre converts carbon dioxide into oxygen

Posted by in categories: 3D printing, health, transportation

This 3D-printed concept wheel by tyre manufacturer Goodyear uses living moss to absorb moisture from the road, before converting it into oxygen through photosynthesis.

The Oxygene tyre was revealed at this year’s Geneva Motor Show that officially kicked off yesterday, 8 March 2018.

The concept is a response to research conducted by the World Health Organisation (WHO) that revealed more than 80 per cent of people who live in urban areas are exposed to air quality levels deemed to be unsafe.

Israeli team develops way to find genetic flaws in fetus at 11 weeks

Posted by in categories: biotech/medical, computing, genetics, health, information science

Researchers at Tel Aviv University say they have developed a new, noninvasive method of discovering genetic disorders that can let parents find out the health of their fetus as early as 11 weeks into pregnancy.

A simple blood test lets doctors diagnose genetic disorders in fetuses early in pregnancy by sequencing small amounts of DNA in the mother’s and the father’s blood. A computer algorithm developed by the researchers analyzes the results of the sequencing and then produces a “map” of the fetal genome, predicting mutations with 99 percent or better accuracy, depending on the mutation type, the researchers said in a study published Wednesday in Genome Research.

The algorithm is able to distinguish between the genetic material of the parents and that of the fetus, said Prof. Noam Shomron of Tel Aviv University’s Sackler School of Medicine led the research, in a phone interview with The Times of Israel.

Your brain needs a fitness plan. Here’s how to keep it in shape

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

This article is reprinted by permission from NextAvenue.org.

The basics of heart health have been drilled into our brains: Eat less saturated fat. Keep moving. Know your “numbers” for cholesterol, blood pressure and BMI.

But what about that brain itself? Although life expectancy has more than doubled since 1900, our “mindspan” — how long we stay cognitively healthy — hasn’t kept pace.

Explainer: What is quantum communication?

Posted by in categories: business, cybercrime/malcode, health, quantum physics

Barely a week goes by without reports of some new mega-hack that’s exposed huge amounts of sensitive information, from people’s credit card details and health records to companies’ valuable intellectual property. The threat posed by cyberattacks is forcing governments, militaries, and businesses to explore more secure ways of transmitting information.

Fungus provides powerful medicine in fighting honey bee viruses

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

In field trials, colonies fed mycelium extract from amadou and reishi fungi showed a 79-fold reduction in deformed wing virus and a 45,000-fold reduction in Lake Sinai virus compared to control colonies.

Though it’s in the early stages of development, the researchers see great potential in this research.

“Our greatest hope is that these extracts have such an impact on viruses that they may help varroa mites become an annoyance for bees, rather than causing huge devastation,” said Steve Sheppard, a WSU entomology professor and one of the paper’s authors. “We’re excited to see where this research leads us. Time is running out for bee populations and the safety and security of the world’s food supply hinges on our ability to find means to improve pollinator health.”

Investors bet billions on health-care start-ups with paltry publication records

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

I remember the #DotCom crash all too well.

The publication record of health-care start-up companies doesn’t seem to matter to investors, according to an analysis of nearly 50 biomedical ‘unicorns’ — venture-capital-backed companies valued at more than US$1 billion. The analysis, led by health-policy researcher John Ioannidis at Stanford University in California, finds no correlation between a company’s market valuation and its publication record — defined as the number of peer-reviewed papers authored directly by a firm. That’s a cause for concern, the authors say.


Firms can achieve fêted ‘unicorn’ valuations without publishing much peer-reviewed science. Health-care start-ups can reach billion-dollar valuations without publishing in peer-reviewed journals, but skipping that step can catch them out.

Neuromelanin-sensitive MRI identified as a potential biomarker for psychosis

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

Researchers have shown that a type of magnetic resonance imaging—called neuromelanin-sensitive MRI (NM-MRI)—is a potential biomarker for psychosis. NM-MRI signal was found to be a marker of dopamine function in people with schizophrenia and an indicator of the severity of psychotic symptoms in people with this mental illness. The study, funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, appears in the Proceedings of the National Academy of Science.

“Disturbances affecting the are associated with a host of mental and neurological disorders, such as schizophrenia and Parkinson’s disease,” said Joshua A. Gordon, M.D., Ph.D., director of NIMH. “Because of the role dopamine plays in these disorders, the ability to measure dopamine activity is critical for furthering our understanding of these disorders, including how to best diagnose and treat them.”

Neuromelanin is a dark pigment created within dopamine neurons of the midbrain—particularly in the substantia nigra, a brain area that plays a role in reward and movement. Neuromelanin accumulates over the lifespan and is only cleared away from cells following cell death, as occurs in neurodegenerative disorders such as Parkinson’s disease. Researchers have found that NM-MRI signal is lower in the substantia nigra of people with Parkinson’s disease, reflecting the cell death that occurs in these patients.
