Scientists build tiny “virus traps” out of DNA origami

Researchers at the Technical University of Munich (TUM) have developed a new method to treat viral infections by making traps. The team folded DNA into nano-capsules with specialized binding points inside them, which could grab hold of viruses and rend… Continue reading Scientists build tiny “virus traps” out of DNA origami

New technique links lithium distribution in the brain to depression

A new technique is allowing researchers to measure endogenous lithium concentrations in the human brain for the very first time. To test the technique researchers compared lithium levels in post-mortem brain tissue between a suicidal subject and a pair… Continue reading New technique links lithium distribution in the brain to depression

Synthetic DNA locks up drugs in the body – and only cancer has the key

No matter how useful a given drug may be, it’s a problem if it has adverse effects on healthy cells. Now researchers have demonstrated a new way to keep drugs on target, by wrapping them in a transport that can only be unlocked by a certain RNA sequenc… Continue reading Synthetic DNA locks up drugs in the body – and only cancer has the key

World’s smallest ultrasound detector is tinier than a blood cell

Scientists in Germany have succeeded in developing the smallest ultrasound detector ever created, which is tinier than a blood cell and opens up new possibilities in what is known as super-resolution imaging. The researchers describe the results as “br… Continue reading World’s smallest ultrasound detector is tinier than a blood cell

Perovskite and organic solar cells tested in space for first time

Perovskite and organic solar cells have proven promising alternatives to the widespread silicon-based devices, and now they’ve been tested in space for the first time. Not only did these solar cells perform well, but they’re much thinner and lighter th… Continue reading Perovskite and organic solar cells tested in space for first time

Could nasal swabs replace skin-prick allergy tests?

Although no one likes getting blood samples drawn or having their skin pricked, these are the most common methods of testing for allergies. Thanks to a new study, however, such uncomfortable pokes could soon be replaced with painless nasal swabs.Contin… Continue reading Could nasal swabs replace skin-prick allergy tests?

Study concludes that electric cars don’t affect pacemakers

Although it doesn’t happen often, it is possible for electromagnetic fields (EMFs) to affect the performance of cardiac implants such as pacemakers. Fortunately for recipients, though, a new study indicates that EMFs produced by electric cars pose no s… Continue reading Study concludes that electric cars don’t affect pacemakers

Drone guidance system uses sound to “see” walls

Many drones already utilize ultrasound to detect individual obstacles lying directly in their path. A proposed new drone system, however, would use sound to determine where all of the walls are within a room – providing guidance when vision- or light-b… Continue reading Drone guidance system uses sound to “see” walls

Interstellar isotopes found in Antarctica were forged from supernovae

In the pure white snow of Antarctica, scientists have found rare isotopes that don’t occur naturally on Earth. The isotope, known as iron-60, is usually forged in the crucible of supernova explosions, and the researchers believe it fell to Ea… Continue reading Interstellar isotopes found in Antarctica were forged from supernovae
