Nanoimaging the intracellular space to aid drug development

by
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 Nanoimaging the intracellular space to aid drug development

The Light in the Tunnel

by
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 The Light in the Tunnel

Western University researchers begin work on COVID-19 vaccine

by
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 Western University researchers begin work on COVID-19 vaccine

Using gold to read cancer’s messages

by

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 Using gold to read cancer’s messages

Scientists succeed in measuring electron spin qubit without demolishing it

by

A group of scientists from the RIKEN Center for Emergent Matter Science in Japan have succeeded in taking repeated measurements of the spin of an electron in a silicon quantum dot (QD), without changing the spin in the process. This type of “non-demolition” measurement is important for creating quantum computers that are fault tolerant. Quantum … Read more Scientists succeed in measuring electron spin qubit without demolishing it

Human Populations survived the Toba volcanic super-eruption 74,000 years ago

by

The Toba super-eruption was one of the largest volcanic events over the last two million years, about 5,000 times larger than Mount St. Helen’s eruption in the 1980s. The eruption occurred 74,000 years ago on the island of Sumatra, Indonesia, and was argued to have ushered in a “volcanic winter” lasting six to ten years, … Read more Human Populations survived the Toba volcanic super-eruption 74,000 years ago

By gum! Scientists find new 110-million-year-old treasure

by

A remarkable new treasure has been found by scientists from the University of Portsmouth – the first fossil plant gum on record. The beautiful, amber-like material has been discovered in 110 million year old fossilised leaves. University of Portsmouth PhD student Emily Roberts, made the discovery while examining fossilised leaves of the Welwitschiophyllum plant, found in the … Read more By gum! Scientists find new 110-million-year-old treasure

Lava flows tell 600-year story of biodiversity loss on tropical island

by

A natural experiment created by an active volcano gives new insight into the long-term negative impacts of human colonisation of tropical forest islands. The findings are published in the British Ecological Society journal, Journal of Ecology. Researchers from the University of Réunion island surveyed vegetation on more than 600 years of lava flows on the slopes … Read more Lava flows tell 600-year story of biodiversity loss on tropical island

USU herpetologist reports surprising evolutionary shift in snakes

by

In the animal kingdom, survival essentially boils down to eat or be eaten. How organisms accomplish the former and avoid the latter reveals a clever array of defense mechanisms. Maybe you can outrun your prey. Perhaps you sport an undetectable disguise. Or maybe you develop a death-defying resistance to your prey’s heart-stopping defensive chemicals that … Read more USU herpetologist reports surprising evolutionary shift in snakes

First direct seismic measurements of mars reveal a geologically active planet

by

The first reports of seismic activity and ground vibrations on Mars are in. The red planet has a moderate level of seismic activity, intermediate between Earth and the Moon. An international team that includes University of Maryland geologists released preliminary results from the InSight mission, which landed a probe on Mars on November 26, 2018. … Read more First direct seismic measurements of mars reveal a geologically active planet
