DNA Breakthrough — How Genetic Shedding Unveils Species Secrets

Posted by in categories: biotech/medical, genetics

Ecologists have shown that the genetic material that species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.

Brain Asymmetry Driven by Task Complexity

Posted by in categories: biotech/medical, life extension, mathematics, robotics/AI

A mathematical model shows how increased intricacy of cognitive tasks can break the mirror symmetry of the brain’s neural network.

The neural networks of animal brains are partly mirror symmetric, with asymmetries thought to be more common in more cognitively advanced species. This assumption stems from a long-standing theory that increased complexity of neural tasks can turn mirror-symmetric neural circuits into circuits existing in only one side of the brain. This hypothesis has now received support from a mathematical model developed by Luís Seoane at the National Center for Biotechnology in Spain [1]. The researcher’s findings could help explain how the brain’s architecture is shaped not only by cognitively demanding tasks but also by damage or aging.

A mirror-symmetric neural network is useful when controlling body parts that are themselves mirror symmetric, such as arms and legs. Moreover, the presence of duplicate circuits on each side of the brain can help increase computing accuracy and offer a replacement circuit if one becomes faulty. However, the redundancy created by such duplication can lead to increased energy consumption. This trade-off raises an important question: Does the optimal degree of mirror symmetry depend on the complexity of the cognitive tasks performed by the neural network?

Cancer-infecting virus warms up cold tumors, boosts immunotherapy: Research

Posted by in categories: biotech/medical, genetics

According to recent research published in the Journal of Experimental Medicine, equipping cancer-infecting viruses with tumor-inhibiting genetic cargo boosts the immune system and supports immunotherapy in reducing or totally eradicating aggressive tumours in mice. The findings pave the path for clinical studies combining oncolytic viruses with immunotherapy.


The study states that cancer-infecting viruses can boost immunity of the body and support immunotherapy.

The 2018 FIFA World Cup is currently ongoing in Russia

Posted by in categories: biotech/medical, internet, nanotechnology, neuroscience

The Video Assistant Referees (VAR) was made official by the FIFA for the World Cup in Russia in order to end the refereeing controversies. this system is considered a total justice for football, VAR and the anti-dopping system have an Achilles’heel: The mind control with brain nanobots. Mind control is a reductive process in which a man is reduced to an animal, machine or slave. Nowadays, the mind control could be developed with invasive neurotechnology as brain nanobots that can control directly the activity of victim neurons stimulating or inhibiting them and thus, control different body’s functions like the motor functions. It could be used by nanomafias in sports like soccer and could being applied on football players of the teams that are participating, nowadays, in the current world cup. The FIFA should be prepared to avoid the mental control and the illicit use of brain nanobots, as they are regarding drugs using the anti-dopping in order to get the justice in world football.

The 2018 FIFA World Cup is the 21st FIFA World Cup, a quadrennial international football that is organized by FIFA. It is currently ongoing in Russia starting from 14 June and will end with the final match on 15 July 2018. The Video Assistant Referees (VAR) was made official by the FIFA for the World Cup in Russia in order to end the refereeing controversies. The FIFA implemented the VAR that is a live support system for referees, which gives them the option of changing decisions that could influence in the scoreboard or in the match incidences although this system is considered the final point for the controversies in refereeing decisions and represent for FIFA and most analysts, a total justice for football.1 The VAR and the anti-dopping system have an Achilles’ heel.

Nanomaterials shape and form influences their ability to cross the blood brain barrier

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

Zhiling Guo, a Research Fellow at the University of Birmingham outlines research into how nanomaterials found in consumer and health-care products can pass from the bloodstream to the brain side of a blood-brain barrier model with varying ease depending on their shape. A new study reveals that this may create potential neurological impacts that could be both positive and negative.

Podcast: Newly approved drug may slow progression of Alzheimer’s

Posted by in categories: biotech/medical, neuroscience

A new episode of our podcast, “Show Me the Science,” has been posted. These episodes feature stories about groundbreaking research, as well as lifesaving and just plain cool stuff involving faculty, staff and students at Washington University School of Medicine in St. Louis.

In this episode, Washington University researchers discuss the Food and Drug Administration’s recent full approval of the drug Leqembi (lecanemab) and what it could mean to the future of Alzheimer’s disease treatments. The drug is approved for use in people with mild dementia from Alzheimer’s disease, but researchers at Washington University’s Charles F. and Joanne Knight Alzheimer Disease Research Center (ADRC), believe the drug, along with other medications in clinical trials, one day may help prevent the development of memory loss and problems with thinking in people who have Alzheimer’s pathology in the brain but who have not yet developed clinical symptoms of the disease.

Barbara Joy Snider, MD, PhD, a professor of neurology and director of clinical trials at the Knight ADRC, says that although Leqembi doesn’t cure Alzheimer’s disease, it slows the decline in memory and thinking, and it also slows the progression of the disorder by removing some amyloid plaques from the brain.

Antibody Prevents Graft Versus Host Disease in Preclinical Tests

Posted by in categories: biotech/medical, health

Even when a bone marrow transplant cures leukemia or lymphoma, GVHD—in which T cells in the donor graft attack the recipient’s own tissues—can still be fatal. The condition is among the leading causes of death and long-term adverse health consequences associated with bone marrow transplants.

Senior co-corresponding authors Ivan Maillard, MD, PhD, a professor of Medicine and vice chief for research in Hematology-Oncology at the Perelman School of Medicine at the University of Pennsylvania, and Leslie S. Kean, MD, PhD, a professor of Pediatrics at Harvard Medical School and director of Pediatric Stem Cell Transplant at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, along with… More.


In new preclinical research, an experimental antibody treatment largely prevented a bone marrow transplant complication called graft versus host disease in the intestines, without causing broad immune suppression, paving the way for clinical trials.
