New Call To Ban Neonicotinoids

By Tim Sandle

Neonicotinoids are a controversial pesticide, used to kill aphids with the aim of protecting crops. The problem is they also – probably – harm bees. Given honeybee populations are in dec worldwide, and the prominent role bees play with pollinating crops, this is by many environmentalists as bad news. Around 16 percent of Europe’s honeybee […]

The Greatest Medical Device Inventors

By Tim Sandle

The science website QMed recently ran a poll of the greatest inventors of medical devices, dating from the nineteenth century to the present day. A medical device refers to any instrument, apparatus, appliance, software, material or other article used for either diagnostic or therapeutic purposes. The range is vast – everything from covering tongue depressors, […]

Why Some Cancer Cells Are Resistant To Treatment

By Tim Sandle

Researchers have been examining how some types of cancer stem cells remain viable in low oxygen conditions. Under such conditions most cells cannot thrive. The matter is of medical concern, since these survivor cells seem resistant to chemotherapy. Further, it is thought that the ability of the cells to survive low oxygen conditions helps […]

Potential Henipavirus Drug Target Identified

By Tim Sandle

Scientists have identified a screening method for the genes that are essential for live henipavirus infection of human cells. This research has identified a specific cell protein called fibrillarin. This protein could be a target for drugs against henipaviruses, and could help people who have contracted this virus. In various countries, particularly the U.S., henipavirus […]

Stem Cell Scientist Fired Over Negligence

By Tim Sandle

Public dismissals in the scientific world are few and far between, which makes the dismissal of Po Macchiarini newsworthy. Karolinska University in Sweden has dismissed the Italian stem cell scientist Dr. Po Macchiarini over a breach of medical ethics. This is not the firing of a junior researcher, for Dr. Macchiarini’s work with stem cells […]

Gut Bacteria Linked To Mental Health Issues

By Tim Sandle

New evidence has emerged that the human microbiome of the gut (the totality of all the microorgani in a given community) can affect, in certain circumstances, mental health and well-being. This has come about, based on information presented at a meeting of the Society for Neuroscience, whereby subjects were administered with a probiotic. The cocktail […]

Five Of The Most Incredible Parasites

By Tim Sandle

Parasitism is a general term for a ‘non-mutual symbiotic relationship’ between species. Here one species – the parasite – benefits at the expense of the other (called the host). Parasites rarely kill their host; however, carrying a parasite can cause a range of unpleasant symptoms. Parasites range in size from tiny, one-celled organi (protozoa) to […]

Does A Brain Parasite Cause Road Rage?

By Tim Sandle

A connection between the parasite Toxoplasma gondii and outbursts of anger has been found. People with intermittent explosive disorder (manifest as outbursts of anger) are twice as likely to have been infected with the parasite, according to a new study. gondii is a parasitic micro-sized animal, and it is capable of infecting virtually all warm-blooded […]

Secrets Of A Deadly Flatworm Revealed

By Tim Sandle

A harmful, parasitic flatworm, responsible for millions of infections worldwide, survives in the human bloodstream for decades. Researchers have been puzzled why the creature can survive for so long. They now have an answer – this is by constantly renewing its skin. The flatworm in question is called Schistosoma mansoni (“schistosomes.”) The worm possesses a […]

Space Bacteria? One Microbe Grows Better In Space

By Tim Sandle

For several years scientists on-board the International Space Station have been examining samples of microorgani and examining how they perform in micro-gravity environments compared with conditions on Earth. Such research is necessary should bacteria and fungi be used as food sources on deep space missions, or even used to help establish a Mars colony. The […]
