The insulin pumps diabetics currently rely on do a great job of delivering the hormone as needed, but need regular replacing due to what are known as fibrils. These form over a day or two as insulin compounds accumulate into clumps and create the risk of blockages, but scientists in Australia have engineered what they say is a safer alternative, with egg yolks serving as their starting point.

The formation of fibrils means that diabetics need to replace their insulin pumps every 24 to 72 hours to avoid the risk of dangerous blockages, which bring with them a risk of life-threatening under-dosing. Beyond the dangers to the patient’s well-being, the need to regularly replace the pump increases the workload needed to manage their disease and means that portions of the medicine often go to waste.

So, there is considerable interest in developing synthetic insulin that doesn’t behave in this way. Researchers at Melbourne’s Florey Institute of Neuroscience and Mental Health approached this problem through a new technique it developed with scientists in Japan, whereby the insulin is engineered from egg yolks to allow for greater freedom over the final design.

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.”
