Beyond The Code: Human Factors In Robotic Surgery Risk Management

A key aspect of human factors in robotic surgery is the training and proficiency of the surgeon. Robotic systems, although designed to enhance precision, rely heavily on the expertise of the individuals operating them. Companies should invest in comprehensive training programs that extend beyond basic certification and promote a culture of continuous learning and skill development.

Simulation-based training, for example, provides a risk-free environment for practicing complex procedures, helping surgeons build confidence and proficiency. Implementing standardized certification processes ensures consistent competency levels among surgeons.

DOOM can now run on a quantum computer with Quandoom port — seminal FPS blood and gore mixed with spooky action

DOOM has been ported to quantum computers, marking another milestone for this seminal 3D gaming title. However, the coder behind this feat admits that there is currently no quantum computer capable of executing (playing) this code right now. All is not lost, though, as Quandoom can run on a classical computer, even a modest laptop, using a lightweight QASM simulator.

Barcelona ICFO-based Quantum Information PhD student Luke Mortimer, AKA Lumorti, is behind this newest port of DOOM. In the ReadMe file accompanying the Quandoom 1.0.0 release, Lumorti quips that “It is a well-known fact that all useful computational devices ever created are capable of running DOOM,” and humorously suggests that Quandoom may be the first practical use found for quantum computers.

How Your Brain Detects Patterns without Conscious Thought

To make sense of the world around us, the brain must process an…

Neurons in certain brain areas integrate ‘what’ and ‘when’ information to discern hidden order in events happening in real time.

By Miryam Naddaf & Nature magazine

The human brain is constantly picking up patterns in everyday experiences — and can do so without conscious thought, finds a study of neuronal activity in people who had electrodes implanted in their brain tissue for medical reasons.

Spinning artificial spider silk into next-generation medical materials

Spider silk is one of the strongest materials on Earth, technically stronger than steel for a material of its size. However, it’s tough to obtain—spiders are too territorial (and cannibalistic) to breed them like silkworms, leading scientists to turn to artificial options.

Teaching microbes to produce the through is one such option, but this has proved challenging because the proteins tend to stick together, reducing the silk’s yield. So, Bingbing Gao and colleagues wanted to modify the natural protein sequence to design an easily spinnable, yet still stable, spider silk using microbes.

The team first used these microbes to produce the silk proteins, adding extra peptides as well. The new peptides, following a pattern found in the protein sequence of amyloid polypeptides, helped the artificial silk proteins form an orderly structure when folded and prevented them from sticking together in solution, increasing their yield.

New filtration material could remove long-lasting chemicals from water

Water contamination by the chemicals used in today’s technology is a rapidly growing problem globally. A recent study by the U.S. Centers for Disease Control found that 98 percent of people tested had detectable levels of PFAS, a family of particularly long-lasting compounds also known as “forever chemicals,” in their bloodstream.

A new filtration material developed by researchers at MIT might provide a nature-based solution to this stubborn contamination issue. The material, based on natural silk and cellulose, can remove a wide variety of these persistent chemicals as well as heavy metals. And, its antimicrobial properties can help keep the filters from fouling.

The findings are described in the journal ACS Nano, in a paper by MIT postdoc Yilin Zhang, professor of civil and environmental engineering Benedetto Marelli, and four others from MIT.

Overcoming Treatment Challenges in Multiple Myeloma: Bispecific Antibodies and CAR T-Cell Therapy

Immunotherapies are the cornerstone of treatment for multiple myeloma (MM), demonstrating clinically meaningful improvements in response rates and progression-free survival (PFS) through the use of more precise, targeted therapies.

Experts discuss immunotherapy advancements and challenges of resistance, efficacy, and toxicity in patient management.

Light-controlled bioassays could diagnose diseases more easily and cost effectively

These OptoAssays allow for the bidirectional, light-induced movement of biomolecules and the reading of test results without the need for additional mechanical washing steps.

An OptoAssay uses a sender and a receiver area, which are brought into contact by adding the test reagent. In the sender area, there is a special protein that reacts to light. This protein can either bind or release specific molecules, depending on the type of light it captures.

When an LED emits at a wavelength of 660 nanometers, the molecules bind to the protein. Upon switching to far-red light with a wavelength of 740 nanometers, the molecules detach from the protein. In the receiver area, there are antibodies specifically designed to recognize and capture the target protein in the test reagent.
