The Dawn Of Humanoid Robotics: A Glimpse Into The Future

Posted by in categories: biotech/medical, robotics/AI, security

The Covid-19 pandemic has posed significant challenges to all industries, including humanoid robotics. Supply chain disruptions and labor shortages have affected development and production. However, the industry has shown resilience, finding ways to resume manufacturing and sustain revenue.

In the ever-evolving robotics industry, challenges like supply chain disruptions and labor shortages demand strategic solutions. Diversify suppliers, build strong relationships and adopt just-in-time manufacturing for resilience. Embrace remote work, upskill the workforce and leverage automation. Monitor risks, maintain buffer stock, foster innovation and network with peers. These strategies ensure the continued growth and success of robotics companies amidst adversity. By staying agile and proactive, the robotics industry can overcome obstacles and lead the way to a transformative future.

Looking ahead, the healthcare industry presents a promising avenue for the application of humanoid robots. From providing security to dispensing pharmaceuticals and assisting patients, humanoid robots could revolutionize healthcare delivery.

Engineering Bacteria into Tumor-Detecting Biosensors

Posted by in categories: biotech/medical, engineering

Additionally, the strategy only works for mutations that have already been defined. Not all tumors have the same mutations, and some cancers manifest a wide array of mutations, but “it happens that colorectal cancer is one of those that has a small set of very common mutations,” said Cooper.

The technique must also translate to humans, though Cooper pointed out, “This is one of those cases where scaling up to humans might actually help it because everything is bigger, so there’s more target DNA and more biosensors you can fit into the gut.”

If further developed and approved for human use, the engineered bacterial biosensors could be used for other applications, such as rapid diagnosis of gut infections. Additionally, shifting from a detection model to a therapeutic mode, the same bacteria could be engineered to release anti-tumor agents upon detecting tumor DNA, rather than sending a signal that they’ve detected it.

Neutrons seek to stop cancer from hijacking a metabolic highway

Posted by in categories: biotech/medical, chemistry

After a highly lauded research campaign that successfully redesigned a hepatitis C drug into one of the leading drug treatments for COVID-19, scientists at the Department of Energy’s Oak Ridge National Laboratory are now turning their drug design approach toward cancer.

In their latest study, published in the journal Communications Chemistry, the team used neutrons and X-rays to draw a roadmap of every atom, and inside a key enzyme that belongs to a that cells dramatically overuse to reproduce.

This new information essentially helps pave the way for developing new drugs that act as roadblocks along the metabolic pathway to cut off the supply of vital resources to cancers cells. The drugs would be designed to target highly aggressive tumor-forming cancers that too often become terminal such as lung, colon, breast, pancreatic and prostate cancers.

Are Fish Oils on the Hook for AF Risk?

Thoughts.


Some studies of fish oil supplements have shown a higher risk for atrial fibrillation with marine omega-3 fatty acids. Is it real? What are the implications for patients taking these capsules?

Heart Organoids Tricked Out With Nanowires Restored Heart Function in Rats

Posted by in categories: biotech/medical, cyborgs, nanotechnology

The tiny, floating blobs of mini-hearts were straight out of Frankenstein. Made from a mixture of human stem cells and a sprinkle of silicon nanowires, the cyborg heart organoids bizarrely pumped away as they grew inside Petri dishes.

When transplanted into rats with heart injuries they lost their spherical shape, spreading out into damaged regions and connecting with the hosts’ own heart cells. Within a month, the rats regained much of their heart function.

It’s not science fiction. A new study this month linked digital electrical components with biological cells into a cyborg organoid that, when transplanted into animal models of heart failure, melded with and repaired living, beating hearts.

Research identifies protein that protects healthy joints from osteoarthritis

Posted by in category: biotech/medical

A previously unstudied protein in the framework of osteoarthritis may be critical in the prevention of the disease, according to groundbreaking new research published in the journal Science Advances, which included work by Justin Parreno, an assistant professor at the University of Delaware.

Osteoarthritis is an irreversible, painful and debilitating condition of the joints characterized by breakdown of the that cushions the ends of the bones, called articular cartilage. It occurs most often in the hands, knees or hips and is the most common type of arthritis, affecting more than 32.5 million Americans, according to the Centers for Disease Control and Prevention.

Parreno was a doctoral student at the University of Toronto when he found that the protein called adseverin helps keep the healthy. This is the first time a specific protein associated with has been identified to be protective against osteoarthritis.

Mineralization of bone matrix regulates tumor cell growth

Posted by in categories: biotech/medical, chemistry

Tumor cells are known to be fickle sleeper agents, often lying dormant in distant tissues for years before reactivating and forming metastasis. Numerous factors have been studied to understand why the activation occurs, from cells and molecules to other components in the so-called tissue microenvironment.

Now, an interdisciplinary Cornell University team has identified a new mechanism regulating growth in the skeleton, the primary site of breast cancer metastasis: mineralization of the bone matrix, a fibrous mesh of organic and inorganic components that determines the unique biochemical and biomechanical properties of our skeleton.

The team’s paper, “Bone-Matrix Mineralization Dampens Integrin-Mediated Mechanosignalling and Metastatic Progression in Breast Cancer,” published Aug. 7 in Nature Biomedical Engineering. The co-lead authors are research associate Siyoung Choi and doctoral student Matthew Whitman.

Detection of Various Microplastics in Patients Undergoing Cardiac Surgery

Posted by in categories: biotech/medical, chemistry

Microplastics have been detected in human stool, lungs, and placentas, which have direct exposure to the external environment through various body cavities, including the oral/anal cavity and uterine/vaginal cavity. Crucial data on microplastic exposure in completely enclosed human organs are still lacking. Herein, we used a laser direct infrared chemical imaging system and scanning electron microscopy to investigate whether microplastics exist in the human heart and its surrounding tissues. Microplastic specimens were collected from 15 cardiac surgery patients, including 6 pericardia, 6 epicardial adipose tissues, 11 pericardial adipose tissues, 3 myocardia, 5 left atrial appendages, and 7 pairs of pre-and postoperative venous blood samples.

A.I. Could Solve Some of Humanity’s Hardest Problems. It Already Has

Posted by in categories: biotech/medical, genetics, robotics/AI

Since the release of ChatGPT, huge amounts of attention and funding have been directed toward chatbots. These A.I. systems are trained on copious amounts of human-generated data and designed to predict the next word in a given sentence. They are hilarious and eerie and at times dangerous.

But what if, instead of building A.I. systems that mimic humans, we built those systems to solve some of the most vexing problems facing humanity?
