Scientists are trying to move beyond conventional model organisms, like fruit flies, zebrafish, yeast, and mice. They started using CRISPR gene-editing technology to craft new model organisms or to study the animals that they are more interested in. The genetic alterations generally take hold but the practical challenges of breeding and maintaining unconventional lab animals persist.
A new gene therapy approach developed at St. Jude Children’s Research Hospital has cured infants born with X-linked severe combined immunodeficiency (SCID-X1), known as “Bubble Boy” disease. The patients recovered with fully functioning immune systems and started producing immune cells, including T cells, B cells, and natural killer (NK) cells. The researchers achieved that by hijacking the HIV virus to replace the mutated gene, called IL2RG, with a corrected copy.
American twin astronauts provided NASA scientists with rare data on how long-term spaceflight affects the human body. While one brother spent a record-setting 340 days in outer space, the other was stranded on Earth. They spent years under a medical microscope. A comparative study on their genetic profiles showed differences in length of telomeres and gene expression, which seemed to diminish slowly over time.
Scientists from Washington University in St. Louis have found a new method to genetically alter bacteria and acquire super-strong spider silk. Farming spiders is incredibly inefficient and finding a way to mass-produce the material would bring us a step away from a ready supply of incredibly resilient fabrics. The method could clear the way for the production of other scarce proteins that could even be used for future space missions.
Inventing a product that allows drinkers to enjoy all the benefits of alcohol and none of its drawbacks was a goal of scientist David Nutt for over a decade. He developed a synthetic alcohol substitute he calls Alcarelle, which could eliminate the downsides of alcohol consumption, from hangovers to alcohol-related cancers and even physical addiction.
An advisory panel to the World Health Organization (WHO) has called for the creation of a global registry to monitor gene-editing research in humans. The recommendations of the 18-person committee are aimed at improving transparency and responsibility in the field. An advisory committee did not recommend banning human gene-editing research, but researchers will have to register with the government before beginning an experiment.
A person living in the modern world today faces more traumas and ordeals in a day than the entire lifetime of a similar person living a hundred years ago. Humanity has come a long way from inventing the wheel to wireless implants that heal nerves. This rapid development has caused considerable repercussions on mankind’s emotional wellbeing.
The Internet has an abundance of articles and posts about cancer. People want to educate themselves more about the harms and threats that simple everyday things may bring, that can potentially cause cancer.
A new study has shown that extracts from crocodile white blood cells can reduce the growth of human cancer cells. Researchers are looking closer into the matter in hopes of finding novel cancer therapies in the future.
Most people who have been to Korean restaurants will be familiar with a signature Korean dish called Kimchi. This traditional dish has been consumed for thousands of years and is made from a mixture of Chinese cabbage, herbs and spices which is then fermented by naturally occurring lactic acid bacteria. Apart from giving kimchi its distinctive taste, it turns out that these probiotic bacteria might also be good for our health.
