Researchers have developed a microneedle patch for monitoring glucose levels using a paper sensor. The device painlessly monitors fluid in the skin within seconds. Anyone can use the disposable patch without training, making it highly practical. Additionally, fabrication is easy, low cost, and the glucose sensor can be swapped for other paper-based sensors that monitor other important biomarkers.

Patches seem to be all the rage these days. There are birth control patches, nicotine patches, and transdermal medicinal patches, just to name a few. Now, a team of researchers led by Beomjoon Kim at the Institute of Industrial Science, The University of Tokyo have developed a patch of needles connected to a paper sensor for diagnosing conditions such as prediabetes...

Water Evaporation, as observed when a puddle of water disappears on a summer day, is a remarkably powerful process. If it were harnessed, the process could provide a[8 clean source of energy to power mechanical machines and devices. In a newly published paper in Nature Materials, an international team of scientists led by researchers at the Advanced Science Research Center at the Graduate Center, CUNY (CUNY ASRC) details the development of shape-shifting crystals that directly convert evaporation energy into powerful motions.

These water-responsive m...

An international team of astronomers today announced the discovery of a rare molecule – phosphine – in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments...

Sophie Lucas (University of Louvain de Duve Institute) and her team succeeded in neutralising a molecule that blocks the immune system against cancer. UCLouvain scientists discovered that this new immunotherapy increases the action of another well-known but not always effective immunotherapy, and that it makes tumour regression possible. This very promising discovery in the fight against cancer is published in the journal Nature Communications.

Cancer immunotherapy is the manipulation of the immune responses naturally present in the human body to fight cancer. Often, these immune responses are blocked by cells or molecules that prevent them from killing cancer cells, and the tumour is able to establish itself and grow.

In 2004, Sophie Lucas, researcher at the University of Louva...
