A combination of ultrasound and nanobubbles allows cancerous tumors to be destroyed without invasive treatments

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

A new technology developed at Tel Aviv University makes it possible to destroy cancerous tumors in a targeted manner, via a combination of ultrasound and the injection of nanobubbles into the bloodstream. According to the research team, unlike invasive treatment methods or the injection of microbubbles into the tumor itself, this latest technology enables the destruction of the tumor in a non-invasive manner.

The study was conducted under the leadership of doctoral student Mike Bismuth from the lab of Dr. Tali Ilovitsh at Tel Aviv University’s Department of Biomedical Engineering, in collaboration with Dr. Dov Hershkovitz of the Department of Pathology. Prof. Agata Exner from Case Western Reserve University in Cleveland also participated in the study. The study was published in the journal Nanoscale.

Dr. Tali Ilovitsh says that their “new technology makes it possible, in a relatively simple way, to inject nanobubbles into the bloodstream, which then congregate in the area of the cancerous . After that, using a low-frequency ultrasound, we explode the nanobubbles, and thereby the tumor.”

Researchers turn asphaltene into graphene for composites

Posted by in categories: 3D printing, energy, engineering

Asphaltenes, a byproduct of crude oil production, are a waste material with potential. Rice University scientists are determined to find it by converting the carbon-rich resource into useful graphene.

Muhammad Rahman, an assistant research professor of materials science and nanoengineering, is employing Rice’s unique flash Joule heating process to convert asphaltenes instantly into turbostratic (loosely aligned) graphene and mix it into composites for thermal, anti-corrosion and 3D-printing applications.

The process makes good use of material otherwise burned for reuse as fuel or discarded into tailing ponds and landfills. Using at least some of the world’s reserve of more than 1 trillion barrels of as a feedstock for graphene would be good for the environment as well.

Meagan Moore, a Biological and Agricultural Engineering student from Louisiana State University (LSU) has 3D printed a full-size model of the human body for use in radiotherapy.

Such models used in radiotherapy mimic the human tissue, and in medical terms are known as imaging phantoms or phantoms. They are used in radiotherapy to estimate the amount of dose delivery and distribution. A customized phantom of a patient can make the whole process more precise.

Accessing Earth’s Core

All of our civilization exists only a thin layer of Earth’s surface, and our deepest mines barely scratch our planet. We often talk about finding new mineral resources on other worlds or asteroids in the future, but are we ignore a treasure beneath our feet, and what other technologies and engineering might we utilize in Earth’s depths?

NASA’s Artemis I Cameras to Offer New Views of Orion, Earth, Moon

Posted by in categories: engineering, space

During Artemis I, NASA’s Space Launch System (SLS) rocket will send the agency’s Orion spacecraft on a trek 40,000 miles beyond the Moon before returning to Earth. To capture the journey, the rocket and spacecraft are equipped with cameras that will collect valuable engineering data and share a unique perspective of humanity’s return to the Moon.

Breathing may measurably modulate neural responses across brain, study finds

Posted by in categories: biotech/medical, engineering, neuroscience

Mental health practitioners and meditation gurus have long credited intentional breathing with the ability to induce inner calm, but scientists do not fully understand how the brain is involved in the process. Using functional magnetic resonance imaging (fMRI) and electrophysiology, researchers in the Penn State College of Engineering identified a potential link between respiration and neural activity changes in rats.

Their results were made available online ahead of publication in eLife. The researchers used simultaneous multi-modal techniques to clear the noise typically associated with brain imaging and pinpoint where breathing regulated .

“There are roughly a million papers published on fMRI—a non-invasive imaging technique that allows researchers to examine in real time,” said Nanyin Zhang, founding director of the Penn State Center for Neurotechnology in Mental Health Research and professor of biomedical engineering.
