Scientists Work Out How To Grow Zombie Mushrooms In A Lab — It Could Help Unlock New Virus-Fighting, Anti-Cancer Drugs

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

A team of scientists from Korea and Egypt have discovered a better way to grow insect-hunting fungi in a lab, according to research published Wednesday in Frontiers in Microbiology.

The fungi can be grown using grains like brown rice but they do not produce much cordycepin, prompting the researchers to suggest insects—which are a richer protein source and the fungi target in nature—as a better alternative. fungi, which infect and zombify insects, are difficult to cultivate but contain chemicals that could help fight cancer and viruses and possibly help treat Covid-19.

Your Body Has an Internal Clock That Dictates When You Eat, Sleep and Might Have a Heart Attack

Posted by in categories: biotech/medical, neuroscience

Have you ever suffered from jet lag or struggled after turning the clock forward or back an hour for daylight saving time? These are examples of you feeling the effects of what researchers call your biological clock, or circadian rhythm – the “master pacemaker” that synchronizes how your body responds to the passing of one day to the next.

This “clock” is made up of about 20,000 neurons in the hypothalamus. This area near the center of the brain coordinates your body’s unconscious functions, such as breathing and blood pressure. Humans aren’t the only lifeforms that have an internal clock system: All vertebrates – or mammals, birds, reptiles, amphibians, and fish – have biological clocks, as do plants, fungi, and bacteria. Biological clocks are why cats are most active at dawn and dusk, and why flowers bloom at certain times of the day.

Key Immune Cells Classified With New Machine Learning Technique

Posted by in categories: biotech/medical, robotics/AI

Researchers from Trinity College Dublin have developed a new, machine learning-based technique to accurately classify the state of macrophages, which are key immune cells. Classifying macrophages is important because they can modify their behaviour and act as pro-or anti-inflammatory agents in the immune response. As a result, the work has a suite of implications for research and has the potential to one day make major societal impact.

For example, this new approach could be of use to drug designers looking to create therapies targeting diseases and auto-immune conditions such as diabetes, cancer and rheumatoid arthritis – all of which are impacted by cellular metabolism and macrophage function.

Because classifying macrophages allows scientists to directly distinguish between macrophage states – based only on their metabolic response under certain conditions – this new information could be used as a diagnosis tool, or to highlight the role of a particular cell type in a disease environment.

DNA gives colloidal crystals shape-shifting and memory abilities

Posted by in categories: biotech/medical, nanotechnology

The crystals are significantly larger than any that have ever been created previously. A hitherto unknown characteristic of colloidal crystals, highly organized three-dimensional arrays of nanoparticles, has been discovered by Northwestern University researchers very recently.


EVANSTON, Ill. — Northwestern University researchers have uncovered a previously unknown property of colloidal crystals, highly ordered three-dimensional arrays of nanoparticles.

The team engineered colloidal crystals with complementary strands of DNA and found that dehydration crumpled the crystals, breaking down the DNA hydrogen bonds. But when researchers added water, the crystals bounced back to their original state within seconds.
