Researchers Find Way To Reverse Aging

Recent experiments conducted in Boston labs have shown reverse aging results among mice and could show similar results in people.

The combined experiments — which were conducted during a span of 13 years — published Thursday (January 12) in the scientific journal Cell reported that old, blind mice regained eyesight, developed smarter brains and built healthier muscle and kidney tissue, challenging the theory that DNA was the only cause of aging, as it proved that chemical and structural changes to chromatin played a factor without altering genetic code.

The research showed that a breakdown in epigenetic information caused the mice to age and the restoration of the epigenome reversed aging effects.

Pop-up Electrode Device Could Help With 3D Mapping of the Brain

Source: Penn State

Understanding the neural interface within the brain is critical to understanding aging, learning, disease progression and more. Existing methods for studying neurons in animal brains to better understand human brains, however, all carry limitations, from being too invasive to not detecting enough information.

A newly developed, pop-up electrode device could gather more in-depth information about individual neurons and their interactions with each other while limiting the potential for brain tissue damage.

Anti-aging gene shown to rewind heart age

By ten years.

An anti-aging gene discovered in a population of centenarians has been shown to rewind the heart’s biological age by 10 years. The breakthrough, published in Cardiovascular Research and led by scientists at the University of Bristol and the MultiMedica Group in Italy, offers a potential target for patients with heart failure.

Associated with exceptional longevity, carriers of healthy mutant , like those living in blue zones of the planet, often live to 100 years or more and remain in . These individuals are also less prone to cardiovascular complications. Scientists believe the gene helps to keep their hearts young by protecting them against diseases linked to aging, such as .

In this new study, researchers demonstrate that one of these healthy mutant genes, previously proved particularly frequent in centenarians, can protect cells collected from patients with failure requiring cardiac transplantation.

Taste Cells’ Role in Immune Response May Lead to Treatment of Taste Loss

Summary: A subset of taste cells may play a key role in the body’s immune response to harmful oral microbes. The findings could help taste loss associated with infections, aging, and dysregulation of the oral microbiome caused by chemotherapy.

Taste cells are heavily exposed to the microbes in the mouth, but their role in helping the body respond to those microbes has not yet been studied in detail.

Improving Intelligence

Improving intelligence has preoccupied society since French psychologist Alfred Binet devised the first IQ test. Since then, the notion that intelligence can be calibrated has opened new avenues into figuring out how it can also be increased.

Psychological scientists have been on the front lines of modifying intelligence. So much intelligence is genetically determined, it is, to a large extent, hereditary. But there are still some areas in which it can be malleable.

Intelligence is generally divided into two categories: fluid intelligence and crystallized intelligence. Fluid intelligence is the ability to reason in an abstract way and solve problems. Someone who can come up with dozens of new uses for, say, a toothbrush would demonstrate superior fluid intelligence. And this is exactly the kind of intelligence that tends to diminish as we grow older. The acquisition of intellectual skills, or the ability to read and comprehend, is known as crystallized intelligence, and this form tends to improve as we age.
