Improved virtual haptic technology enables uniform tactile sensation across displays
A virtual haptic implementation technology that allows all users to experience the same tactile sensation has been developed. A research team led by Professor Park Jang-Ung from the Center for Nanomedicine within the Institute for Basic Science (IBS) and Professor Jung Hyun Ho from Severance Hospital’s Department of Neurosurgery has developed a technology that provides consistent tactile sensations on displays.
This research was conducted in collaboration with colleagues from Yonsei University Severance Hospital. It was published in Nature Communications on August 21, 2024.
Virtual haptic implementation technology, also known as tactile rendering technology, refers to the methods and systems that simulate the sense of touch in a virtual environment. This technology aims to create the sensation of physical contact with virtual objects, enabling users to feel textures, shapes, and forces as if they were interacting with real-world items, even though the objects are digital.
Bowel cancer trial sees all patients disease-free in huge breakthrough
A bowel cancer trial has seen all participants emerge cancer-free, indicating “extremely positive” development for treatment.
Bowel cancer is the fourth most common cancer in the UK, with cases in under-50s seeing a rise in recent years. Thanks to campaigners like Dame Deborah James, more people are having bowel cancer checks – important, as chances of survival are greater when caught early.
When caught in the early stages, 90 per cent of those treated with stage one bowel cancer will survive for five or more years. The figure falls to 65 per cent at stage three, and to 10 per cent at stage four.
New filtration system removes ‘forever chemicals’ from water
A breakthrough filtration system developed by MIT researchers offers hope for removing harmful “forever chemicals” — dangerous pollutants that have plagued water supplies globally for decades.
These long-lasting pollutants, known as PFAS, persist in the environment and have contaminated water sources worldwide.
A recent study by the U.S. Centers for Disease Control found that 98% of people tested had detectable levels of PFAS in their bloodstream, highlighting the severity of the contamination.
How the brain’s inner chamber governs our state of consciousness
In hospital operating rooms and intensive care units, propofol is a drug of choice, widely used to sedate patients for their comfort or render them fully unconscious for invasive…
Propofol works quickly and is tolerated well by most patients when administered by an anesthesiologist.
But what’s happening inside the brain when patients are put under and what does this reveal about consciousness itself?
Investigators at Michigan Medicine, who are studying the nature of consciousness, have successfully used the drug to identify the intricate brain geometry behind the unconscious state, offering an unprecedented look at brain structures that have traditionally been difficult to study.
The First Person to Receive an Eye and Face Transplant Is Recovering Well
A man who received a partial face and eye transplant after a serious accident does not have any vision in the transplanted eye, but the eye itself is still alive.

Molecular jackhammers: A breakthrough in cancer treatment
Cancer treatment has reached a new milestone with the development of an innovative method to destroy cancer cells using molecular jackhammers, offering hope for more targeted and efficient therapies.
This cutting-edge approach utilizes advanced molecular science to disrupt cancer cells in a way that could minimize harm to healthy tissue.
A collaborative team of scientists has found that stimulating aminocyanine molecules with near-infrared light causes them to vibrate in sync, producing enough force to effectively rupture the membranes of cancer cells without invasive procedures.
AI is the next frontier in cancer treatment
In the ongoing battle against cancer, a new AI approach is being explored that holds the potential to revolutionize the future of personalized cancer treatments.
The technology, which is an amalgamation of artificial intelligence, molecular dynamics simulations, and network analysis, aims to predict the binding sites on cancer-related proteins. This will pave the way for a faster development of treatments tailored for individual cancer patients.
The study was led by Dr. Rafael Bernardi, an associate professor of biophysics in the Department of Physics at Auburn University. As part of a collaborative effort with the University of Basel and ETH Zurich, the team is breaking barriers on how we understand and fight cancer.
