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 […]



Hacking Humans : Search & replace gene editing is here

November 1st, 2019 at 11:21 am » Comments Off

The introduction of CRISPR changed the world of genetic engineering by allowing researchers to “cut and paste” DNA. But the process can introduce errors that produce unpredictable results. A recently published report in the journal Nature by David Liu, a Harvard university biologist, describes a new process that is more like a “search and replace” […]



Gene editing transforms gel into shape-shifting material

September 10th, 2019 at 3:23 am » Comments Off

  The CRISPR technique can trigger the new material to release drugs or pick up biological signals Is there anything CRISPR can’t do? Scientists have wielded the gene-editing tool to make scores of genetically modified organisms, as well as to track animal development, detect diseases and control pests. Now, they have found yet another application […]



Gene-edited cattle have a major screwup in their DNA

September 6th, 2019 at 11:29 am » Comments Off

  Bid for barnyard revolution is set back after regulators find celebrity “hornless” bovines contaminated by bacterial genes. They were the poster animals for the gene-editing revolution, appearing in story after story. By adding just a few letters of DNA to the genomes of dairy cattle, a US startup company had devised a way to […]



In a 1st, doctors in U.S. use CRISPR tool to treat patient with genetic disorder

August 16th, 2019 at 12:25 am » Comments Off

Victoria Gray, 34, of Forest, Miss., volunteered for one of the most anticipated medical experiments in decades: the first attempt to use the gene-editing technique CRISPR to treat a genetic disorder in the U.S. For the first time, doctors in the U.S. have used the powerful gene-editing technique CRISPR to try to treat a patient […]



Wait, What? The first human-monkey hybrid embryo was just created in China

August 14th, 2019 at 6:57 am » Comments Off

Last week, news broke that a prominent stem cell researcher is making human-monkey chimeras in a secretive lab in China. The story, first reported by the Spanish newspaper El País, has all the ingredients of a bombshell. First, its protagonist is the highly-respected Dr. Juan Carlos Izpisúa Belmonte, a Spanish-born stem cell biologist at the […]
