A drone is an autonomous unmanned aerial vehicle (UAV) that can be programmed for automatic routing and delivery. These come handy in delivery medicines which is easier to carry and can add value to the pharma supply chain. Drone helps to deliver to places with the high expense involved or poor infrastructure and thereby plays a significant role in last-mile delivery.
The pace with which they are now being used for delivery, even Amazon is experimenting with the delivery mechanism offered by drone as its logistics and transport market is forecast to grow 20% in coming times.

An international team of cancer researchers has developed a new type of copper-based nanoparticle that can kill tumor cells in mice. While the technology showed effectiveness on its own, by combining it with immunotherapy the scientists say it produced long-lasting effects, quickly killing off any cancer cells that dared to return.
The therapy centers on new knowledge around tumors’ aversion to certain types of nanoparticles. The research team made up of scientists from KU Leuven, the University of Bremen, the Leibniz Institute of Materials Engineering, and the University of Ioannina, discovered that tumor cells were particularly sensitive to nanoparticles made from copper and oxygen.
Once these copper oxide nanoparticles enter a living organism they dissolve and become toxic, killing off cancer cells that happen to be in the area. Key to the new nanoparticle design was the addition of iron oxide, which the researchers say enables it to kill off cancer cells while leaving healthy cells intact.
Published today in Science, the research team from the Peter Doherty Institute for Infection and Immunity (Doherty Institute), the Olivia Newton-John Cancer Research Institute and CSL Limited say this breakthrough of discovering how gamma-delta T cells become activated addresses a question that has baffled scientists for 25 years.
The study by University of Melbourne’s Marc Rigau, Ph.D. student at the Doherty Institute, was co-led by Dr. Adam Uldrich, a Senior Research Fellow at the Doherty Institute, Professor Dale Godfrey a laboratory head at the Doherty Institute, and Dr. Andreas Behren, a Laboratory Head from the Olivia Newton-John Cancer Research Institute.
Dr. Uldrich explained that gamma-delta T cells are known to respond to the presence of small molecules, known as phosphoantigens, that are produced by bacteria and cancer cells.
The year of treating the untreatable: 2019 breakthroughs that could transform medicine.
What the reasons underlying these impairments are is yet unclear but scientists at the Center for Regenerative Therapies of TU Dresden (CRTD) wanted to investigate if increasing the number of stem cells in the brain would help in recovering cognitive functions, such as learning and memory, that are lost during ageing.”

Ein jeder wird es irgendwann erleben: Je älter wir werden, desto schwieriger wird es für unser Gehirn, neue Dinge zu lernen und sich an sie zu erinnern. Die Gründe hinter diesen Beeinträchtigungen sind oft unklar. Nun haben Wissenschaftler des Zentrums für Regenerative Therapien der TU Dresden (CRTD) untersucht, ob eine Erhöhung der Anzahl von Hirnstammzellen helfen würde, kognitive Funktionen wie Lernen und Gedächtnis wiederzuerlangen, die im Laufe des Alterns verloren gehen.
Die Forschungsgruppe von Prof. Federico Calegari hat dazu eine im eigenen Labor entwickelte Methode verwendet: Im Gehirn alter Mäuse stimulierten die Wissenschaftler den dort vorhandenen kleinen Pool neuronaler Stammzellen so, dass sich die Menge dieser Stammzellen und damit auch die Anzahl der aus ihnen erzeugten Gehirnzellen erhöhte. Das Team beobachtete, dass diese zusätzlichen Neuronen überleben und sogar neue Kontakte zu benachbarten Zellen knüpfen können. In einem nächsten Schritt untersuchten die Wissenschaftler eine wichtige Aufgabe des Gehirns, die ähnlich wie bei der Maus auch beim Menschen im Laufe des Alterns verloren geht: die Navigationsfähigkeit.
Proteins are often called the working molecules of the human body. A typical body has more than 20,000 different types of proteins, each of which is involved in many functions essential to human life.
Now, Purdue University researchers have designed a novel approach to use deep learning to better understand how proteins interact in the body – paving the way to producing accurate structure models of protein interactions involved in various diseases and to design better drugs that specifically target protein interactions. The work is released online in Bioinformatics.
“To understand molecular mechanisms of functions of protein complexes, biologists have been using experimental methods such as X-rays and microscopes, but they are time- and resource-intensive efforts,” said Daisuke Kihara, a professor of biological sciences and computer science in Purdue’s College of Science, who leads the research team. “Bioinformatics researchers in our lab and other institutions have been developing computational methods for modeling protein complexes. One big challenge is that a computational method usually generates thousands of models, and choosing the correct one or ranking the models can be difficult.”
Guardian of the Amazon! — Come hear the recent ideaXme (http://radioideaxme.com/) episode where we are joined by Ms. Nemonte Nenquimo, President of the Waorani Pastaza Organization, CONCONAWEP (Coordinating Council of the Waorani Nationality of Ecuador), following their recent landmark legal victory against the Ecuadorian government, leading to 500,000 acres of Amazon rainforest protected from oil drilling and timber companies (English voice over — Spanish audio link to be posted soon) — #Ideaxme #Amazon #Rainforest #Jungle #Ecuador #Waorani #Huaorani #Amerindian #Environment #Trees #Herbal #EthnoMedicine #Sustainability #Ayahuasca #ClimateChange #GretaThunberg #Health #Wellness #Longevity #Aging #IraPastor #Bioquark #Regenerage
Ira Pastor, ideaXme exponential health ambassador, interviews Ms. Nemonte Nenquimo, President of the Waorani Pastaza Organization (CONCONAWEP — Coordinating Council of the Waorani Nationality of Ecuador). This is an English language voice over of Ms Nenquimo’s audio interview.
Ira comments:
Today we have a fascinating guest joining us on the ideaXme show from a rather remote location, to discuss ethnomedicine, environmental conservation and protection, entheogens (the topic of bio-active plant substances for spiritual and religious practices), as well as the themes of bravery and perseverance.
Who Are the Waorani?
