New Directed Energy Device for Biomedical and Military Defense Applications

Posted by in categories: biotech/medical, military

An invention from Purdue University innovators may provide a new option to use directed energy for biomedical and defense applications.

The Purdue invention uses composite-based nonlinear transmission lines (NLTLs) for a complete high-power microwave system, eliminating the need for multiple auxiliary systems. The interest in NLTLs has increased in the past few decades because they offer an effective solid-state alternative to conventional vacuum-based, high-power microwave generators that require large and expensive external systems, such as cryogenic electromagnets and high-voltage nanosecond pulse generators.

NLTLs have proven effective for applications in the defense and biomedical fields. They create directed high-power microwaves that can be used to disrupt or destroy adversary electronic equipment at a distance. The same technology also can be used for biomedical devices for sterilization and noninvasive medical treatments.

Targeting tumors with nanoworms

Posted by in categories: bioengineering, biotech/medical, chemistry, nanotechnology, supercomputing

Getting closer.


Drugs and vaccines circulate through the vascular system reacting according to their chemical and structural nature. In some cases, they are intended to diffuse. In other cases, like cancer treatments, the intended target is highly localized. The effectiveness of a medicine —and how much is needed and the side effects it causes —are a function of how well it can reach its target.

“A lot of medicines involve intravenous injections of drug carriers,” said Ying Li, an assistant professor of mechanical engineering at the University of Connecticut. “We want them to be able to circulate and find the right place at the right time and to release the right amount of drugs to safely protect us. If you make mistakes, there can be terrible side effects.”

Harvard scientists create gene-editing tool that could rival CRISPR

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

Harvard’s Wyss Institute has created a new gene-editing tool that enable scientist to perform millions of genetic experiments simultaneously.


Researchers from the Harvard’s Wyss Institute for Biologically Inspired Engineering have created a new gene-editing tool that can enable scientists to perform millions of genetic experiments simultaneously. They’re calling it the Retron Library Recombineering (RLR) technique, and it uses segments of bacterial DNA called retrons that can produce fragments of single-stranded DNA.

When it comes to gene editing, CRISPR-Cas9 is probably the most well-known technique these days. It’s been making waves in the science world in the past few years, giving researchers the tool they need to be able to easily alter DNA sequences. It’s more accurate than previously used techniques, and it has a wide variety of potential applications, including life-saving treatments for various illnesses.

India is churning out billion-dollar startups. Now they need to start making money

Posted by in categories: biotech/medical, economics

The mood a year later is very different, despite a brutal surge in coronavirus cases that is threatening the economic recovery. India’s startup community has found itself in an unprecedented funding bonanza.


In the first four months of 2021, 11 startups have attained unicorn status, meaning they’ve reached a valuation of at least $1 billion.

AI Challenges For The Health IT Industry: Should We Expect Electronic Doctors?

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

Yes, but they wont be trusted til 2035.


Current trends in AI use in healthcare lead me to posit that this market will significantly grow in the coming years. So, should leaders in healthcare expect the emergence of a fully automated electronic physician, sonographer or surgeon as a replacement for the human healthcare professional? Can the development of AI in healthcare help overcome the difficulties the industry faces today? To figure all this out, I would like to analyze the current challenges of using AI in healthcare.

Let’s discuss two promising examples: the application of AI in diagnosis and reading images, and the use of robotic systems in surgery.

Surprise in the Deep Sea: Researchers Discover Unexpected Paths on the Ocean Floor

Posted by in category: biotech/medical

Sponges: They are considered to be one of the most primitive forms of animal life, because they have neither locomotion organs nor a nervous system. A team around deep-sea scientist Antje Boetius has now discovered that sponges leave trails on the sea floor in the Arctic deep sea. They conclude that the animals might move actively — even if only a few centimeters per year. They are now publishing these unique findings in the journal Current Biology.

The surprise was great when researchers looked at high-resolution images of the sea floor of the Arctic deep sea in detail: Path-like tracks across the sediments ended where sponges were located. These trails were observed to run in all directions, including uphill. “We conclude from this that the sponges might actively move across the sea floor and leave these traces as a result of their movement,” reports Dr Teresa Morganti, sponge expert from the Max Planck Institute for Marine Microbiology in Bremen. This is particularly exciting because science had previously assumed that most sponges are attached to the seafloor or are passively moved by ocean currents and, usually down slopes.

But being such effective survivors may come at a cost.

A group of Cancer Research UK-funded scientists are beginning to discover new vulnerabilities in cancer , which emerge when they enter “survival mode.”
