Valentine’s Day 2024: Scientists create gel to mend broken hearts — How does it work?

Scientists have created a wood pulp hydrogel to strengthen anti-cancer medications and restore damaged cardiac tissue.

Now that they have created a novel hydrogel that can be utilised to repair damaged heart tissue and enhance cancer therapies, you can cure a broken heart on Valentine’s Day, according to SciTech Daily.

Dr Elisabeth Prince, a researcher in chemical engineering at the University of Waterloo, collaborated with scientists from Duke University and the University of Toronto to design a synthetic material that is made of wood pulp-derived cellulose nanocrystals. The material’s unique biomechanical qualities are recreated by engineering it to mimic the fibrous nanostructures and characteristics of human tissues.

Timelapse of Future Technology 2 (Sci-Fi Documentary)

This timelapse of future technology begins with 2 Starships, launched to resupply the International Space Station. But how far into the future do you want to go?

Tesla Bots will be sent to work on the Moon, and A.I. chat bots will guide people into dreams that they can control (lucid dreams). And what happens when humanity forms a deeper understanding of dark energy, worm holes, and black holes. What type of new technologies could this advanced knowledge develop? Could SpaceX launch 100 Artificial Intelligence Starships, spread across our Solar System and beyond into Interstellar space, working together to form a cosmic internet, creating the Encyclopedia of the Galaxy. Could Einstein’s equations lead to technologies in teleportation, and laboratory grown black holes.

Other topics covered in this sci-fi documentary video include: the building of super projects made possible by advancing fusion energy, the possibilities of brain chips, new age space technology and spacecraft such as a hover bike developed for the Moon in 2050, Mars colonization, and technology predictions based on black holes, biotechnology, and when will humanity become a Kardashev Type 1, and then Type 2 Civilization.

Scientists discover hidden army of lung flu fighters

Scientists have long thought of the fluid-filled sac around our lungs merely as a cushion from external damage. Turns out, it also houses potent virus-eating cells that rush into the lungs during flu infections.

Not to be confused with phages, which are viruses that infect bacteria, these cells are macrophages, immune cells produced in the body.

“The name macrophage means ‘big eater.’ They gobble up bacteria, viruses, , and dying cells. Really, anything that looks foreign, they take it up and destroy it,” said UC Riverside virologist Juliet Morrison, who led the discovery team. “We were surprised to find them in the lungs because nobody has seen this before, that these cells go into the lung when there’s an infection.”

Promising new therapeutic approach for treating metastatic pancreatic cancer

A research paper published in Nature Cancer details new insights into the role of efferocytosis—the burying of dead cells—in pancreatic cancer that spreads to the liver.

Liver metastasis occurs in 40–50% of people with pancreatic ductal adenosarcoma (PDAC), and there are currently no effective therapies to cure patients that have .

Led by University of Liverpool’s Professor Michael Schmid and colleagues, this study found PDAC metastases to show high levels of immunosuppressive macrophages, a type of white blood cell that promotes .

New Non-Opioid Drug Blocks Pain Signals Before They Can Reach Brain

As the opioid crisis worsens, one Boston-based pharmaceutical company has used some impressive biology to create what it says amounts to a non-addictive, non-opioid painkiller.

As the New York Times reports, Vertex Pharmaceuticals seems to have shown some promising results in Phase 3 clinical trials, announced earlier this week in a statement, for patients who experienced “moderate-to-severe acute pain” after getting surgery.

Whereas opioids generally target both the brain and the body, which ultimately leads to their addictiveness, non-opioid drugs like Vertex’s VX-548 focus on peripheral nerves, or those outside of the brain and spine, the NYT explains. By blocking pain at the source, the logic goes, it can be averted before reaching the brain and developing the kind of feedback loop that lends itself to dependency.

The short lifespan of conventional batteries means they either cannot be used or have significant drawbacks in situations where it is not feasible to charge or replace them. For example, pacemakers, satellites, high-altitude drones or even spacecraft are low-power electrical devices where long life of the energy source is needed.

What we’re doing

A team of physicists and chemists from the University of Bristol have grown a man-made diamond that, when placed in a radioactive field, is able to generate a small electrical current.

Scientists create new laser-based method to 3D-print artificial cartilage

A new laser-based approach has been introduced to produce artificial cartilage using 3D printing technology.

In this approach, researchers from TU Wien printed living cells within tiny football-like spheroids.

The team hopes this technique could be used to cultivate lab-grown tissue capable of replacing damaged cartilage in humans. It is a strong connective tissue found in various parts of the body that protects our joints and bones.

Mucus contains vital data to help address diseases such as inflammatory bowel disease and colon cancer

New research from UBC Okanagan could make monitoring gut health easier and less painful by tapping into a common—yet often overlooked—source of information: the mucus in our digestive system that eventually becomes part of fecal matter.

Researcher Dr. Kirk Bergstrom and post-graduate student Noah Fancy of UBCO’s Biology department have discovered a non-invasive technique to study MUC2, a critical gut protein, from what we leave behind in the bathroom.

Theie findings are published in the Journal of Biological Chemistry.
