Amazon is working to develop biometric scanners to link handprints to credit cards, allowing shoppers to buy with the swipe of their palm

January 24th, 2020 at 12:49 pm » Comments Off

Amazon is working with credit card companies to create terminals to allow users to pay for items with biometric data from their handprint. The online retailer previously patented such technology, which had been presumed to be used at its Whole Food stores Amazon currently allows shoppers at its Amazon Go grocery store to pay for […]



The major discoveries that could transform the world in the next decade

January 2nd, 2020 at 12:20 pm » Comments Off

Here’s what scientists are really excited about. The last decade ushered in some truly revolutionary advances in science, from the discovery of the Higgs boson to the use of CRISPR for Sci-Fi esque gene editing. But what are some of the biggest breakthroughs still to come? Live Science asked several experts in their field what […]



Lab-grown meat also creates an unexpected benefit: Ethical zebra burgers

November 4th, 2019 at 1:57 pm » Comments Off

“What are the odds that these animals contain the tastiest, most nutritionally rich food offerings?” The term “cultivated meat” is industry’s preferred language for the admittedly unappetizing-sounding “lab-grown meat,” and it has the potential to actually change the world. This lab-grown meat could reduce the various impacts of raising animals for slaughter, which is the […]



Mini brains grown in the laboratory produce brainwaves. Now what?

October 20th, 2019 at 1:08 pm » Comments Off

It’s hard to study the human brain. It is the most complex in the animal kingdom with its massive collection of neurons, 80-100 billion to be exact, three times more than chimpanzees. Research relating our brains to the brains of mice and monkeys can only go so far. And because of this complexity, scientists often […]



Scientists create a device that can mass-produce human embryoids

October 4th, 2019 at 12:22 am » Comments Off

  These human embryo-like structures (top) were synthesized from human stem cells; they’ve been stained to illustrate different cell types. Images (bottom) of the “embryoids” in the new device that was invented to make them. Yi Zheng/University of Michigan, Ann Arbor Scientists have invented a device that can quickly produce large numbers of living entities that […]



Gene-hacking mosquitoes to be infertile backfired spectacularly

September 25th, 2019 at 12:25 pm » Comments Off

    Best-Laid Plans On its surface, the plan was simple: gene-hack mosquitoes so their offspring immediately die, mix them with disease-spreading bugs in the wild, and watch the population drop off. Unfortunately, that didn’t quite pan out. The genetically-altered mosquitoes did mix with the wild population, and for a brief period the number of […]



Mini-brains grown in a lab have human-like brain activity

September 10th, 2019 at 3:29 am » Comments Off

A new study promises new paths to research mental illness, but raises questions about whether so-called organoids could develop consciousness Alysson Muotri was dumbfounded when the pea-sized blobs of human brain cells that he was growing in the lab started emitting electrical pulses. He initially thought the electrodes he was using were malfunctioning. Muotri was […]



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 […]



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 […]



How scientists built a ‘living drug’ to beat cancer

August 7th, 2019 at 12:07 pm » Comments Off

IN 2010, EMILY Whitehead was diagnosed with Acute Lymphoblastic Leukemia, a cancer of certain cells in the immune system. THIS IS THE most common form of childhood cancer, her parents were told, and Emily had a good chance to beat it with chemotherapy. Remission rates for the most common variety were around 85 percent. It […]



Proteins trapped in glass could yield new medicinal advances

August 7th, 2019 at 11:49 am » Comments Off

The protein, captured in an extremely thin piece of glass — around 50 nanometres in diameter, is sliced up, atom by atom, with the help of an electrical field. It is then analysed through Atom Probe Tomography, and the 3D structure is recreated on a computer. Credit: Small: Volume 15, Issue 24, Atom Probe Tomography […]
