‘MasSpec Pen’ for accurate cancer detection during surgery

A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur. The “MasSpec Pen,” a handheld device in development, could someday enable surgeons to distinguish between cancerous and healthy tissue … Read more

Positive relationships boost self-esteem, and vice versa

Does having close friends boost your self-esteem, or does having high self-esteem influence the quality of your friendships? Both, according to a meta-analysis of more than two decades of research, published by the American Psychological Association. “For the first time, we have a systematic answer to a key question in the field of self-esteem research: … Read more

Realistic robots get under Galápagos lizards’ skin

Male lava lizards are sensitive to the timing of their opponents’ responses during contest displays, with quicker responses being perceived as more aggressive, a study in Behavioural Ecology and Sociobiology suggests. To avoid injury from male-to-male contests, some animal species display behaviours such as color changes or sequences of movements that showcase body size and … Read more

Adelphi, OHIO researchers determine dinosaur replaced teeth as fast as sharks

A meat-eating dinosaur species (Majungasaurus) that lived in Madagascar some 70 million years ago replaced all its teeth every couple of months or so, as reported in a new study published today in the open-access journal PLOS ONE, surprising even the researchers. In fact, Majungasaurus grew new teeth roughly two to thirteen times faster than those of other … Read more

DNA from 31,000-year-old milk teeth leads to discovery of new group of ancient Siberians

Two children’s milk teeth buried deep in a remote archaeological site in north eastern Siberia have revealed a previously unknown group of people lived there during the last Ice Age. The finding was part of a wider study which also discovered 10,000 year-old human remains in another site in Siberia are genetically related to Native … Read more

Nanoimaging the intracellular space to aid drug development

Iridium-based metallodrugs

Iridium-based metallodrugs are emerging as novel tools to destroy cancer cells by disrupting their intracellular redox balance. Scientists at IMDEA Nanociencia and researchers at ALBA, ESRF and CNB-CSIC have joined efforts to image the anticancer agent at work in the cryopreserved intracellular nano-space. Chemotherapeutics are key players in the clinical setting to fight most types … Read more

The Light in the Tunnel

The Light in the Tunnel

Researchers from the Universidad Autónoma de Madrid, IMDEA Nanociencia and IFIMAC have developed a new method for the fabrication and characterization of atomic-sized photonic cavities, by exploiting the mechano-quantum tunnel effect. This discovery may be fundamental for the understanding and design of new, nanometric size, opto-electronic devices which will be key for the development of … Read more

Western University researchers begin work on COVID-19 vaccine

COVID-19

A multidisciplinary team of Western University researchers is beginning work on the development of a COVID-19 vaccine. They join the global effort to curb the spread of the virus which to-date has been confirmed in 225,000 cases worldwide, and has caused more than 9,000 deaths. The team is rapidly mobilizing its efforts to establish and … Read more

Using gold to read cancer’s messages

A novel blood test that uses gold nanoparticles to detect cancer has also been shown to identify signals released by cancer cells which could result in earlier diagnosis and better treatment. New research has revealed the nanotechnology developed by University of Queensland scientists can detect and monitor extracellular vesicles (EVs) in the bloodstream. Australian Institute … Read more
