From an article by Dr. ir Johannes Drooghaag :
Blockchain, by some seen as the answer to every problem, is promoted by many, including myself, as a possible solution for many cyber security issues. The structure of blockchain, combining distributed ledger, consensus on proof of work and proof of stake, encryption by design and linked blocks, provides a lot of layers of protection. This does however not mean that blockchain can’t be hacked at all, it just means that it would take a lot of effort and resources to do so.
What we have to be very careful with is creating false sense of security, something I keep stressing during my workshop Cybersecurity for Road Warriors (and Couch Potatoes) and publications on this topic, by hyping the security aspects way beyond reality. With the hype around blockchain and all blockchain based crypto-currencies, and “better than anything because we use blockchain” projects, we are setting ourselves up for yet another security myth by believing that blockchain is unhackable. This article is a collection of findings and theories during research on the currently known safety issues related to blockchain. Some attack vectors are already out in the field and have lead to high profile thefts and hacks, others are theoretical and listed for the purpose of demonstrating the concept.
A potential milestone in cancer therapy
Researchers from the University of Bern, Inselspital, University Hospital Bern, and the University of Connecticut have made a significant breakthrough in the fight against cancer. They identified a previously unknown weak point of prostate [...]
Cardiovascular Crystal Ball: New Tool Predicts Future Heart Disease Risk
Faculty members at the UM School of Medicine have created a cutting-edge tool that enables the early identification and assessment of risks in vulnerable patients. Heart disease, being the leading cause of death globally, [...]
Scientists analyze a single atom with X-rays for the first time
In the most powerful X-ray facilities in the world, scientists can analyze samples so small they contain only 10,000 atoms. Smaller sizes have proved exceedingly difficult to achieve, but a multi-institutional team has scaled [...]
AI Demonstrates Superior Performance in Predicting Breast Cancer
AI algorithms outperformed traditional clinical risk models in a large-scale study, predicting five-year breast cancer risk more accurately. These models use mammograms as the single data source, offering potential advantages in individualizing patient care [...]
Stanford Medicine Reveals: Tiny DNA Circles Defying Genetic Laws Drive Cancer Formation
Tiny circles of DNA harbor cancer-associated oncogenes and immunomodulatory genes promoting cancer development. They arise during the transformation from pre-cancer to cancer, say Stanford Medicine-led team. Tiny circles of DNA that defy the accepted laws of [...]
Death to Blood Cancer Cells: New Drug Combination Could Revive the Power of Leading Treatment
Future clinical trials will be conducted to investigate whether the combination of chloroquine and venetoclax can prevent disease recurrence. Although new drugs have been developed to induce cancer cell death in individuals with acute [...]
Illuminating Science: X-Rays Visualize How One of Nature’s Strongest Bonds Breaks
Scientists have deciphered how an activated catalyst breaks down the strong carbon-hydrogen bonds in potent greenhouse gas methane, according to a study published in Science. Using advanced X-ray technology and quantum-chemical calculations, they tracked the [...]
Using magnetic nanoparticles as a rapid test for sepsis
Qun Ren, an Empa researcher, and her team are currently developing a diagnostic procedure that can rapidly detect life-threatening blood poisoning caused by staphylococcus bacteria. Staphylococcal sepsis is fatal in up to 40% of [...]
