How sunlight on the skin directly affects the gut microbiome

Posted by in categories: biotech/medical, genetics

New research from a team of Canadian scientists has for the first time demonstrated how exposure to Narrow Band Ultraviolet B light (UVB) can directly influence gut microbiome diversity in humans. The research hypothesizes that this result is modulated by vitamin D and presents evidence of a novel skin-gut communication pathway.

Autoimmune diseases such as inflammatory bowel disease (IBD) and multiple sclerosis are thought to be caused by a number of environmental and genetic factors. Gut bacterial diversity, exposure to sunlight and vitamin D levels, have all been observed as influential factors for inflammatory disease, however a new study is asserting a causal chain may link all three of these elements.

The new research examined 21 female subjects who were all administered three 60-second full-body UVB exposure sessions across one week. Blood and fecal samples were taken from all subjects at the beginning and end of the study to track changes to vitamin D levels and gut bacterial diversity. Half of the subjects were noted as having taken vitamin D supplements across the prior three winter months.

I’m an academic doctor. But research from for-profit companies may be the best way to help patients and science in the future

Such studies are distrusted by professionals because of possible conflicts of interest. But important research will be increasingly conducted, funded or aided by such firms.

Scientists say solar technology may detect, attack cancer cells

Posted by in categories: biotech/medical, chemistry, solar power, sustainability

A study claims a new way to detect and attack cancer cells using technology traditionally reserved for solar power as the results showcased dramatic improvements.

The results published in Scientific Reports said that dramatic improvements were seen in light-activated fluorescent dyes for disease diagnosis, image-guided surgery and site-specific tumor treatment.

“We’ve tested this concept in breast, lung cancer and skin cancer cell lines and mouse models, and so far it’s all looking remarkably promising,” said Sophia, Michigan State University’s (MSU) biochemistry and molecular biologist.

What are the ethical consequences of immortality technology?

Posted by in categories: biotech/medical, finance, life extension

Immortality has gone secular. Unhooked from the realm of gods and angels, it’s now the subject of serious investment – both intellectual and financial – by philosophers, scientists and the Silicon Valley set. Several hundred people have already chosen to be ‘cryopreserved’ in preference to simply dying, as they wait for science to catch up and give them a second shot at life. But if we treat death as a problem, what are the ethical implications of the highly speculative ‘solutions’ being mooted?

Of course, we don’t currently have the means of achieving human immortality, nor is it clear that we ever will. But two hypothetical options have so far attracted the most interest and attention: rejuvenation technology, and mind uploading.

Like a futuristic fountain of youth, rejuvenation promises to remove and reverse the damage of ageing at the cellular level. Gerontologists such as Aubrey de Grey argue that growing old is a disease that we can circumvent by having our cells replaced or repaired at regular intervals. Practically speaking, this might mean that every few years, you would visit a rejuvenation clinic. Doctors would not only remove infected, cancerous or otherwise unhealthy cells, but also induce healthy ones to regenerate more effectively and remove accumulated waste products. This deep makeover would ‘turn back the clock’ on your body, leaving you physiologically younger than your actual age. You would, however, remain just as vulnerable to death from acute trauma – that is, from injury and poisoning, whether accidental or not – as you were before.

New Drug-Delivery technology promises Efficient, Targeted Cancer Treatment

Posted by in categories: biotech/medical, nanotechnology

A precise and non-toxic treatment that targets lung cancer cells at the nanoscale is able to effectively kill the cells even at a low dose. Researchers from Washington State University and the Department of Energy’s Pacific Northwest National Laboratory (PNNL) used tiny tubes made from organic molecules called peptoids to deliver cancer-killing drugs in a targeted manner.

The biologically-inspired nanotubes, which are about a hundred thousand times thinner than a human hair, were rolled up from membrane-like nanosheets. The drug molecules, fluorescent dyes and cancer-targeting molecules were precisely placed within the nanotubes, enabling them to track the efficiency of drug delivery into the cancer cells.

The new technology allows the two drugs – one for chemotherapy and the other for a less-invasive photodynamic therapy treatment – to be delivered directly to the cancer cells. Photodynamic therapy uses a chemical that, when exposed to light, releases reactive oxygen species (ROS) that kill cancer cells. The researchers’ dual-drug approach enabled the use of a lower dose of the cancer drugs than using a single drug, leading to effective killing of cancer cells with low toxicity.
