Amazon Prime Air lands FAA approval for drone deliveries

Posted by in categories: drones, health, robotics/AI

Amazon Prime Air has cleared a regulatory hurdle, moving the online retail giant one step closer to dropping packages off at your doorstep with drones. The US Federal Aviation Administration on Saturday issued Amazon Prime Air a “a Part 135 air carrier certificate,” allowing it to begin commercial drone deliveries in the US.

“Amazon Prime Air’s concept uses autonomous [unmanned aircraft systems] to safely and efficiently deliver packages to customers,” said a spokesperson for the FAA on Monday. “The FAA supports innovation that is beneficial to the public, especially during a health or weather-related crisis.”

Amazon and other companies are trying to make drones the future of deliveries.

IBM has built a new drug-making lab entirely in the cloud

Posted by in categories: biotech/medical, health, robotics/AI

The news: IBM has built a new chemistry lab called RoboRXN in the cloud. It combines AI models, a cloud computing platform, and robots to help scientists design and synthesize new molecules while working from home.

How it works: The online lab platform allows scientists to log on through a web browser. On a blank canvas, they draw the skeletal structure of the molecular compounds they want to make, and the platform uses machine learning to predict the ingredients required and the order in which they should be mixed. It then sends the instructions to a robot in a remote lab to execute. Once the experiment is done, the platform sends a report to the scientists with the results.

Why it matters: New drugs and materials traditionally require an average of 10 years and $10 million to discover and bring to market. Much of that time is taken up by the laborious repetition of experiments to synthesize new compounds and learn from trial and error. IBM hopes that a platform like RoboRXN could dramatically speed up that process by predicting the recipes for compounds and automating experiments. In theory, it would lower the costs of drug development and allow scientists to react faster to health crises like the current pandemic, in which social distancing requirements have caused slowdowns in lab work.

Virological assessment of hospitalized patients with COVID-2019

Posted by in categories: biotech/medical, health, robotics/AI

The coronavirus disease 2019 (COVID-19) pandemic has had a global impact on all aspects of health care, including surgical procedures. For urologists, it has affected and will continue to influence how we approach the care of patients preoperatively, intraoperatively, and postoperatively. A risk-benefit assessment of each patient undergoing surgery should be performed during the COVID-19 pandemic based on the urgency of the surgery and the risk of viral illness and transmission. Patients with advanced age and comorbidities have a higher incidence of mortality. Routine preoperative testing and symptom screening is recommended to identify those with COVID-19. Adequate personal protective equipment (PPE) for the surgical team is essential to protect health care workers and ensure an adequate workforce. For COVID-19 positive or suspected patients, the use of N95 respirators is recommended if available. The anesthesia method chosen should attempt to minimize aerosolization of the virus. Negative pressure rooms are strongly preferred for intubation/extubation and other aerosolizing procedures for COVID-19 positive patients or when COVID status is unknown. Although transmission has not yet been shown during laparoscopic and robotic procedures, efforts should be made to minimize the risk of aerosolization. Ultra-low particulate air filters are recommended for use during minimally invasive procedures to decrease the risk of viral transmission. Thorough cleaning and sterilization should be performed postoperatively with adequate time allowed for the operating room air to be cycled after procedures. COVID-19 patients should be separated from noninfected patients at all levels of care, including recovery, to decrease the risk of infection. Future directions will be guided by outcomes and infection rates as social distancing guidelines are relaxed and more surgical procedures are reintroduced. Recommendations should be adapted to the local environment and will continue to evolve as more data become available, the shortage of testing and PPE is resolved, and a vaccine and therapeutics for COVID-19 are developed.

The first reported cases of coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), originated in Wuhan City, Hubei Province, China in December 2019. This respiratory disease spread outside of China, leading to outbreaks in Korea, Iran, Italy, and, eventually, the United States and the rest of the world. On March 11, 2020, the World Health Organization (WHO) declared the outbreak to be a pandemic. At the time of this writing, there are currently more than 1.3 million confirmed cases worldwide, with the total deaths numbering more than 74,000.1 This pandemic is unlike anything that has been seen in recent history.

From a urologic surgery perspective, many questions arise regarding the immediate and long-term care of our patients. The goal of this article is to summarize some of the current information available on preoperative, intraoperative, and postoperative care. As we gain more knowledge about how the virus behaves, this body of literature will inevitably change.

‘Cold Tube’ Invented to Beat the Summer Heat More Efficiently Than Air Conditioning

Posted by in categories: biotech/medical, health

Chilled panels use less energy than conventional A/C and work in open spaces.

Many people beat the summer heat by cranking the air conditioning. However, air conditioners guzzle power and spew out millions of tons of carbon dioxide daily. They’re also not always good for your health—constant exposure to central A/C can increase risks of recirculating germs and causing breathing problems.

There’s a better alternative, say a team of researchers from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre.

Robot Skin 3D Printer Close to First-in-Human Clinical Trials

Posted by in categories: 3D printing, bioprinting, biotech/medical, government, health, robotics/AI

In just two years a robotic device that prints a patient’s own skin cells directly onto a burn or wound could have its first-in-human clinical trials. The 3D bioprinting system for intraoperative skin regeneration developed by Australian biotech start-up Inventia Life Science has gained new momentum thanks to major investments from the Australian government and two powerful new partners, world-renowned burns expert Fiona Wood and leading bioprinting researcher Gordon Wallace.

Codenamed Ligō from the Latin “to bind”, the system is expected to revolutionize wound repairs by delivering multiple cell types and biomaterials rapidly and precisely, creating a new layer of skin where it has been damaged. The novel system is slated to replace current wound healing methods that simply attempt to repair the skin, and is being developed by Inventia Skin, a subsidiary of Inventia Life Science.

“When we started Inventia Life Science, our vision was to create a technology platform with the potential to bring enormous benefit to human health. We are pleased to see how fast that vision is progressing alongside our fantastic collaborators. This Federal Government support will definitely help us accelerate even faster,” said Dr. Julio Ribeiro, CEO, and co-founder of Inventia.

Scientists find that Citriodiol, ingredient in insect repellent, can kill COVID-19

Posted by in categories: biotech/medical, health

British scientists have discovered that an active ingredient found in insect repellent can kill COVID-19, according to a report.

Researchers at the UK’s Defense Science and Technology Laboratory determined that Citriodiol can help fight coronavirus in a preliminary study, Sky News reported.

Insect repellents containing Citriodiol are not believed to be enough alone to protect people from the virus but can be used as an additional layer of defense along with face masks, hand washing and other health recommendations, according to the report.

Mosquitoes armed with bacteria beat back dengue virus

Posted by in categories: biotech/medical, health


—In a handful of cities around the world, mosquitoes have been armed with a microscopic weapon against disease. The bacterium Wolbachia pipientis blocks the insects’ ability to spread fearsome viruses such as dengue, Zika, and chikungunya. Since 2011, researchers have been injecting Wolbachia into the eggs of Aedes aegypti mosquitoes and releasing the hatched insects, which spread this protection to their offspring. But the field has been waiting for evidence that this approach actually reduces disease in people.

Field trials suggest public health benefit to spreading Wolbachia.
