Researchers reveal a much richer picture of the past with new DNA recovery technique

September 17th, 2020 at 11:35 am » Comments Off

A shot of the Klondike region in the Yukon, where the permafrost samples containing sediment DNA, were collected. Researchers at McMaster University have developed a new technique to tease ancient DNA from soil, pulling the genomes of hundreds of animals and thousands of plants—many of them long extinct—from less than a gram of sediment. The […]



CRISPR-based COVID test is rapid, accurate and costs less than $1

September 9th, 2020 at 11:35 am » Comments Off

CRISPR’s claim to fame may be gene editing—and turning the scientific community on its head when it first debuted—but it may have another trick up its sleeve. Recent studies have indicated CRISPR tools have the potential for in vitro diagnostics, something Chinese scientists have leveraged to develop a 100% accurate COVID-19 test that can be […]



Body fat transformed by CRISPR gene editing helps mice keep weight off

September 1st, 2020 at 9:58 am » Comments Off

  A 3D illustration of brown fat cells, which both burn and store energy  White fat cells can be turned into energy-burning brown fat using CRISPR gene-editing technology. These engineered cells have helped mice avoid weight gain and diabetes when on a high-fat diet, and could eventually be used to treat obesity-related disorders, say the […]



Can aging really be ‘treated’ or ‘cured’?

August 18th, 2020 at 1:15 pm » Comments Off

As time passes, our fertility declines and our bodies start to fail. These natural changes are what we call ageing.  In recent decades, we’ve come leaps and bounds in treating and preventing some of the world’s leading age-related diseases, such as coronary heart disease, dementia and Alzheimer’s disease. But some research takes an entirely unique […]



Molecules identified that reverse cellular aging process

May 15th, 2020 at 12:24 am » Comments Off

A new discovery paves the way for novel drugs that could help safeguard DNA and slow the aging process Central to a lot of scientific research into aging are tiny caps on the ends of our chromosomes called telomeres. These protective sequences of DNA grow a little shorter each time a cell divides, but by […]



Crumpled graphene makes ultra-sensitive cancer DNA detector

April 3rd, 2020 at 11:22 am » Comments Off

Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient’s blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it more than ten thousand times more sensitive to DNA by creating electrical “hot spots,” researchers at the University […]



You’re likely to get the Coronavirus

March 4th, 2020 at 11:27 am » Comments Off

Most cases are not life-threatening, which is also what makes the virus a historic challenge to contain. In May 1997, a 3-year-old boy developed what at first seemed like the common cold. When his symptoms—sore throat, fever, and cough—persisted for six days, he was taken to the Queen Elizabeth Hospital in Hong Kong. There his […]



Scientists might have accidentally cured cancer

January 26th, 2020 at 5:20 pm » Comments Off

  Research Into Cancer Conducted At The Cancer Research UK Cambridge Institute New treatment for killing cancer cells may have accidentally been discovered by a group of British scientists, according to reports. Cardiff University’s research team found a T-Cell that attaches itself onto human cancers, and kills them while ignoring healthy cells. Although in its […]



3D Printing and the murky ethics of replicating bones

January 15th, 2020 at 12:50 pm » Comments Off

Bone scan databases offer scientists new ways to study human remains. But some worry they could be misused. Ten years ago, it wasn’t possible for most people to use 3D technology to print authentic copies of human bones. Today, using a 3D printer and digital scans of actual bones, it is possible to create unlimited […]



The world’s first Gattaca baby tests are finally here

November 19th, 2019 at 12:15 pm » Comments Off

The DNA test claims to let prospective parents weed out IVF embryos with a high risk of disease or low intelligence. Anxious couples are approaching fertility doctors in the US with requests for a hotly debated new genetic test being called “23andMe, but on embryos.” The baby-picking test is being offered by a New Jersey […]



CRISPR enzyme programmed to kill viruses in human cells

November 10th, 2019 at 5:15 pm » Comments Off

Researchers harness Cas13 as an antiviral and diagnostic for RNA-based viruses Researchers have now turned a CRISPR RNA-cutting enzyme into an antiviral that can be programmed to detect and destroy RNA-based viruses in human cells. Many of the world’s most common or deadly human pathogens are RNA-based viruses — Ebola, Zika and flu, for example […]



Japan approves scientist’s plan to create world’s first Humanimals

November 1st, 2019 at 11:33 am » Comments Off

  For the first time, a government is supporting a plan to create animal embryos with human cells and bring them to term, resulting in a type of humanimal known as a human-animal chimera. According to Nature, a committee from Japan’s science ministry signed off on a request by researchers to grow human pancreases in […]
