Researchers at the National University of Singapore (NUS) have potentially found a new way to combat hypertension by discovering how blood pressure is controlled.
What is hypertension?
High blood pressure, or hypertension, rarely has noticeable symptoms. However, if it is left untreated, your risk of serious problems, such as heart attack and stroke, is increased.
An interview with Laura Weston, medical doctor and artist, on transhumanism and rejuvenation.
The belief that science and art run on parallel tracks is largely unsubstantiated, and Dr. Laura Weston—a scientist, an artist, and a LEAF volunteer—is a great example of this. Dr. Weston is both a molecular pathologist and a painter, and she has recently launched her own art gallery. Being a passionate life extensionist and, more generally, a transhumanist, Laura undertook this project because of her belief that art can and should take part in shaping a better future for everyone; art hosted in her gallery will certainly do this in the traditional way of conveying a message but also more directly, since part of the proceeds from sales will be destined for conservation charities, medical research, and even LEAF—which we are all most grateful for.
Artists and art enthusiasts who want to make a difference for important causes, including life extension, now have their chance to do so by contributing their own art or buying their favorite works. Pieces hosted at Katrin Brunier—Laura’s nom de plume—are examples of abstract works inspired by transhumanist themes; you can admire a sample below or visit the gallery’s Instagram page.
There is a history of insects’ acceptability as ingredients for Chinese medicine, as pets, and even as food. Yet in selling the idea to the general public, especially those living in big cities, there is still a way to go.
Hundreds of cockroach farmers across China are unleashing the insects’ potential in the country’s war on waste, in medicine, and deep or stir-fried.
Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher. Then, in the decades following Miescher’s discovery, other scientists—notably, Phoebus Levene and Erwin Chargaff—carried out a series of research efforts that revealed additional details about the DNA molecule, including its primary chemical components and the ways in which they joined with one another. Without the scientific foundation provided by these pioneers, Watson and Crick may never have reached their groundbreaking conclusion of 1953: that the DNA molecule exists in the form of a three-dimensional double helix.
M en with previously “untreatable” prostate cancer are being kept alive by a new drug in what experts believe may be a breakthrough for patients with the worst form of the disease.
A British trial has for the first time shown that state-of-the art immunotherapy can be used to target prostate tumours.
The study at the Royal Marsden Hospital in London found more than a third of men who had run out of existing options were still alive and one in ten had not seen their tumours grow after a year of taking Pembrolizumab, which targets a gateway helps the immune system to attack cancer cells.
A blood test could one day save millions by allowing doctors to screen for cancer before patients show symptoms.
The test, called a “liquid biopsy,” screens for 10 types of the disease by detecting trace amounts of DNA released into the bloodstream by cancer cells. So far, it has proven particularly capable of detecting ovarian and pancreatic cancer, both of which have significantly lower mortality rates when caught early enough to perform surgery as a means of removing the cancer. Unfortunately, most are caught after patients begin to show symptoms, which is often after the cancer has spread to other parts of the body.
“This is potentially the holy grail of cancer research, to find cancers that are currently hard to cure at an earlier stage when they are easier to cure,” says Dr. Eric Klein of Cleveland Clinic’s Taussig Cancer Institute. “We hope this test could save many lives.”

8 Amazing CRISPR gene editing projects that could change life as we know it.
Since it burst onto the scene a decade ago, CRISPR-Cas9 has shaken the field of genetics to its core. Offering a new genomic editing tool that’s faster, cheaper and more accurate than previous approaches, it opens up an astonishing breadth of possible applications.
