Depression and Anxiety Exhaust the Heart, Literally

Posted by in categories: biotech/medical, neuroscience

A 1967 publication titled “Mortality of Bereavement” discovered that bereaved relatives had a 7-fold increased risk of dying within the following year. Despite that the cause of death was undetermined, this is the first scientific evidence indicating that extreme sadness kills.

Coined in 1991, Takotsubo cardiomyopathy — or broken heart syndrome — mimic aspects of a heart attack such as shortness of breath, fainting, and chest pain. But, oddly, they have no blocked arteries. Instead, some parts of the heart stopped moving and other heart muscles try to compensate for this. This turns the heart into an irregular shape, like that of an octopus pot — hence, the name “Takotsubo” (‘Tako’ means octopus and ‘tsubo’ means pot in Japanese). This condition is reversible but can be fatal at times. Takotsubo cardiomyopathy is triggered by intense emotions or stressful life events such as the death of a loved one and losing (or even winning) a lot of money. This is why “heartbroken” from sadness is a legitimate phenomenon.

Research advances further confirm that sadness, or more accurately emotional stress, destroy the heart in many ways. The mind-heart connection extends to far more than just the broken heart syndrome. Convincing epidemiological evidence ascertains that emotional pains can lead to heart diseases, the major killer worldwide, and this linkage is underpinned by biology.

Physical non-equilibria for prebiotic nucleic acid chemistry

Posted by in categories: biotech/medical, chemistry

Physical non-equilibria can drive cycles of replication and selection chemistries that play a role in the prebiotic replication of DNA and RNA. This Perspective offers insights from astrophysics, geoscience and microfluidics on how various environments on early Earth could have hosted such reactions.

Blobs of human brain planted in rats offer new treatment hope

Posted by in categories: biotech/medical, neuroscience

The team behind the work suggest that eventually doctors might be able to grow blobs of brain tissue from a patient’s own cells in the lab and use them to repair brain injuries caused by stroke or trauma.

“This is incredibly exciting to me as a physician,” said Isaac Chen, a physician and assistant professor of neurosurgery at the University of Pennsylvania.

The study is the latest in the rapidly growing and ethically complex field of brain organoids. Scientists have shown that when cultivated in the right conditions, neurons begin to form tiny brain-like structures, allowing scientists to investigate developmental conditions such as autism and a wide range of basic neuroscience questions.

Auburn University researchers combining alligator, catfish DNA: ‘Who would have thought to do this?’

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

It sounds like the start of a Southern gothic horror thriller. Auburn University scientists have been putting alligator DNA in catfish. It’s delicious, but with less chance for infection. Don’t worry, it won’t bite back. MIT Technology Review recently highlighted the work of Rex Dunham, Baofeng Su and their colleagues at Auburn University, who have used genetic modification to reduce problems of disease in catfish farming.

Scientists created ‘cyborg cells’ that are partially alive, but can be programmed

Posted by in categories: biotech/medical, cyborgs

Scientists have managed to do something truly groundbreaking. According to a new paper published in Advanced Science, researchers have created programmable cyborg cells that could help revolutionize medicine and environmental cleanup efforts. The new research, which was carried out by researchers at the University of California, Davis, shows that it is possible to create semi-living cyborg cells that retain the capabilities of living cells, but are unable to divide and grow.

In 2021, Craig Gibbons was diagnosed with Lyme disease. His doctor prescribed him antibiotics, but the medication failed to eliminate one of his most debilitating symptoms: a lasting brain fog that made it difficult for him to focus or recall information.

So he went with a different approach: at-home brain stimulation.
