Easter Island soil provided the anti-ageing chemical

A miraculous ‘elixir of youth’ which could extend the human life span by more than a decade is being developed by scientists.  The anti-ageing pill was created from a chemical found in the soil of Easter Island  –  one of the most remote and mysterious places on the planet.  In tests on animals, the chemical increased life expectancy by a staggering 38 per cent.

Like Burrs On Your Clothes, Molecule-size Capsules Can Deliver Drugs By Sticking To Targeted Cells

This image shows that after 36 hours nearly every target cell (round gray spheres) has ingested a nanocapsule containing a small-interfering RNA (in red).

It is now possible to engineer tiny containers the size of a virus to deliver drugs and other materials with almost 100 percent efficiency to targeted cells in the bloodstream.

Artificial Liver For Drug Tests

Artificial liver for drug tests.

If you have hay fever, headaches or a cold, it’s only a short way to the nearest chemist. The drugs, on the other hand, can take eight to ten years to develop. Until now animal experiments have been an essential step, yet they continue to raise ethical issues. “Our artificial organ systems are aimed at offering an alternative to animal experiments,” says Professor Heike Mertsching of the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB in Stuttgart.

Scientists Warn Virus Could Cause Heart Disease In Adults

Scientists Warn Virus Could Cause Heart Disease In Adults

The risk of heart attack is increased by the virus, spread through bodily fluids 

New research suggests that a common infection affecting 60 to 99 per cent of adults could result in high blood pressure and hardening of the arteries – leading causes of heart disease, stroke and kidney disease.

Instant Immunity From A Vaccine

Instant Immunity From A Vaccine

 

A new approach primes antibodies to instantly attack cancers, HIV, and other diseases.

The body’s immune system is often likened to an army, and vaccines to training exercises that build up defenses against pathogens. By exposing the immune system to inactive forms of a virus or bacteria, a vaccine trains antibodies to fight off a real pathogen in the event of an invasion. However, while vaccines prepare antibodies to identify an attacker, they often don’t give specific instructions on exactly how to bring it down. Some antibodies may successfully hit a pathogen’s weak spot, while others may miss the mark entirely. That’s part of the reason why it normally takes several weeks or months for some vaccines to build up an effective immune response.

Transplanted Stem Cells Undo Birth Defects

Transplanted Stem Cells Undo Birth Defects 

 Neural stem cells, tagged green with a fluorescent dye, have been transplanted among the brain cells (red) of a mouse born with brain damage after its mother was given heroin during pregnancy.

By injecting stem cells directly into the brain, scientists have successfully reversed neural birth defects in mice whose mothers were given heroin during pregnancy. Even though most of the transplanted cells did not survive, they induced the brain’s own cells to carry out extensive repairs.

Tissue Engineers Creating Complex Tissue They Call Living Legos

Tissue Engineers Creating Complex Tissue They Call Living Legos

 Living Legos: Polymer building blocks whose complexity mimics that of human tissues.

Tissue engineers are ambitious. If they had their way, a dialysis patient could receive a new kidney made in the lab from his own cells, instead of waiting for a donor organ that his immune system might reject. Likewise, a diabetic could, with grafts of lab-made pancreatic tissue, be given the ability to make insulin again. But tissue engineering has stalled in part because bioengineers haven’t been able to replicate the structural complexity of human tissues. Now researchers have taken an important first step toward building complex tissues from the bottom up by creating what they call living Legos. These building blocks, biofriendly gels of various shapes studded with cells, can self-assemble into complex structures resembling those found in tissues.
