In 2017, the number of children immunized – 116.2 million – was the highest ever reported. The Region of the Americas achieved maternal and neonatal tetanus elimination, leaving only 15 countries yet to achieve elimination. Since 2010, 113 countries have introduced new vaccines, and more than 20 million additional children have been vaccinated. Nevertheless, this …
Harvard researchers describe a vaccine approach that uses an injectable scaffold loaded with a selection of tumor-expressed peptides. It is a path to a personalized anti-cancer vaccine. The strategy proved more effective at stimulating anti-tumor responses and, importantly, a tumor-specific immune memory in mouse models that kept the animals rejecting tumor cells at least half …
A new way of producing the seasonal flu vaccine could speed up the process and provide better protection against infection. For decades, vaccine manufacturers have used chicken eggs to grow the flu virus strains included in the seasonal flu shot. But because these human strains frequently mutate to adapt to their new environment in eggs, …
The number of children dying worldwide of diarrhea fell by a third between 2005 and 2015, researchers have found. The study says better access to clean water and sanitation is key, with fewer weak and malnourished children becoming infected. New vaccines have also had a positive impact. However, diarrhea is still the fourth-biggest killer of …
The World Health Organization called today for accelerated scale-up of efforts to prevent malaria and save lives. In sub-Saharan Africa, which shoulders 90% of the global malaria burden, more than 663 million cases have been averted since 2001. Insecticide-treated nets have had the greatest impact, accounting for an estimated 69% of cases prevented through control …
Positive outcome of trials in Niger fuels hope that vaccine can protect children in sub-Saharan Africa and beyond from infection that causes often fatal diarrhoea. A vaccine capable of enduring scorching temperatures for months at a time could strike a decisive blow in the fight against rotavirus, preventing nearly half a million children around the …
Alphabet’s Google has been quietly expanding a Waze ridesharing pilot program to more people. As of Thursday, it’s available to any interested Waze users in the San Francisco area. Unlike typical ridesharing services, Waze really is ridesharing: it lets people already driving somewhere connect with passengers and pick up some extra cash while doing it. …
A few days ago Nextbigfuture noted that China’s one belt one road plan is to spend 9% of China’s GDP over decades to build out the ports, airports, rail, factories and cities of countries in Asia and Africa and Europe as China’s develops a modern Silk road. This spending of trillions of dollars will boost …
China is 3d printing titanium parts for a new fighter aircraft, which would have been impossible to create as a single piece using any subtractive manufacturing technique. In the past, the only method was to reduce the design standards, split it into multiple parts, and then assemble it, affecting the performance of the fighter and …
Two approaches are being developed for terahertz frequency devices. 1. The Solid State Power Amplifier (SSPA), which in 2014 was certified by Guinness World Records as the world’s fastest solid state chip, able to operate at THz speeds. This device, made of the semiconductor indium phosphide (InP), also can boost the power of a wide …
The Lockheed Martin F-22 Raptor is a single-seat, twin-engine, all weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF’s Advanced Tactical Fighter program, the aircraft was designed primarily as an air superiority fighter, but has additional capabilities including ground attack, electronic warfare, and signals intelligence roles. …
