1st gene-edited snakes use mysterious ‘Turing patterns’ to achieve near-perfect hexagonal scales

Posted by in categories: biotech/medical, genetics

Remember all those low rate scifi horror movies with big snakes, let’s see if the bookie will take bet on when we have a first big one (on the run from the facility)

Scientists used CRISPR editing to make the world’s first genetically modified snakes, giving new insight into how the reptiles develop their patterned scales.

Physiological Integration of Taste and Metabolism

Posted by in category: neuroscience

Since taste receptor cells (TRCs) undergo rapid turnover, maintaining neurosensory integrity (i.e., sweet taste receptors signaling to “sweet” neurons) is essential (Fig. 2, shown here). The labeled-line model of taste transmission connects taste reception and signal integration in the brain.

Backstabbing, bluffing and playing dead: has AI learned to deceive? — podcast

Posted by in category: robotics/AI

As AI systems have grown in sophistication, so has their capacity for deception, according to a new analysis from researchers at Massachusetts Institute of Technology (MIT). Dr Peter Park, an AI existential safety researcher at MIT and author of the research, tells Ian Sample about the different examples of deception he uncovered, and why they will be so difficult to tackle as long as AI remains a black box.

The State of CRISPR and Gene Editing 2024

Posted by in categories: bioengineering, biotech/medical, food

Following the landmark approval of the first CRISPR-based cell therapy in December 2023, the CRISPR community is looking ahead to the next wave of commercial successes, fueled by continued innovation in the development of new gene editing and delivery tools and technologies. Equally exciting advances are occurring in livestock editing, xenotransplantation, and many other specialties.

In The State of CRISPR and Gene Editing virtual summit, GEN proudly gathers a tantalizing line-up of luminaries from academia and industry to discuss the latest research developments, innovations, and advanced technologies that are expanding the CRISPR toolbox, delivering new therapies to patients and safeguarding our food supply.

The Dark Universe: Why we’re about to solve the biggest mystery in science

Posted by in categories: cosmology, science

Tiny, fuzzy blobs. I’ve spent a lot of time in the last few years looking at images of tiny, fuzzy blobs. They’re only ever a few pixels wide, like smudges on a photo, but they could be the key that unlocks the mystery of dark matter.

The blobs are galaxies: swirling pools of stars and planets suspended in space, millions of light-years away from Earth. The images were collected by an advanced camera with a 1m (3.3ft) lens mounted on the giant Victor M Blanco Telescope, 2,200m (7,200ft) up in the mountains of the Coquimbo Region of Chile.

Why a New Inhalable Lung Cancer Treatment Is So Promising

Posted by in categories: bioengineering, biotech/medical, genetics, health

Cells in the human body chat with each other all the time. One major way they communicate is by releasing tiny spheres called exosomes. These carry fats, proteins, and genetic material that help regulate everything from pregnancy and immune responses to heart health and kidney function.

Now, a new Columbia University study in Nature Nanotechnology demonstrated that these “nanobubbles” can deliver potent immunotherapy directly to tough-to-treat lung cancer tumors via inhalation.

“Exosomes work like text messages between cells, sending and receiving information,” said lead researcher Ke Cheng, PhD, professor of biomedical engineering at Columbia. “The significance of this study is that exosomes can bring mRNA-based treatment to lung cancer cells locally, unlike systemic chemotherapy that can have side effects throughout the body. And inhalation is totally noninvasive. You don’t need a nurse to use an IV needle to pierce your skin.”

Scientists unveil Mission Impossible 4-inspired smart contact lenses

Posted by in categories: augmented reality, computing, health

Chinese scientists have developed a new type of lens that can be used for health care and augmented reality (AR). Based on radio frequency, the eye-tracking smart contact lenses don’t require battery or conventional silicon chips and are biocompatible and imperceptible.

Set to be used for human-machine interaction (HMI), the smart contact lenses rely on tracking eye movements. The lenses use methods like pupil center corneal reflection and electrooculography (EOG) to track eye movements.
