Nigeria becomes world’s first country to introduce ‘revolutionary’ meningitis vaccine

Nigeria has become the first country to roll out a “revolutionary” five-in-one vaccine against meningitis, the World Health Organization has announced. The Men5CV vaccine offers a powerful shield against the five major strains of the meningococcal bacteria that cause the disease. Known by the brand name MenFive, it provides broader protection than the vaccine currently used in much of Africa.

British scientists develop new bifacial solar technology that generates more power at reduced cost

Scientists from the University of Surrey in England, working with colleagues at the University of Cambridge, the Chinese Academy of Sciences, Xidian University, and Zhengzhou University, have developed a flexible perovskite solar panel that use electrodes made of tiny carbon nanotubes. The researchers demonstrated that in addition to producing more energy than traditional solar panels, “the material cost of an all-carbon-electrode-based bifacial PSC is about 70% lower than that of a monofacial device.”

Scientists successfully 3D-print human skin tissue into open wounds

Scientists at Pennsylvania State University have successfully 3D-printed living human skin tissue directly into the open wounds of rats for the first time in history. This bioengineering milestone could pave the way for major developments in reconstructive surgery — or even human hair treatments. Current methods of skin and hair reconstruction — like skin grafts — often result in scars, meaning this discovery could lead to a more seamless treatment for humans.

New satellite pinpoints global methane pollution in real-time

MethaneSAT, developed by the Environmental Defense Fund in partnership with the New Zealand Space Agency, is the size of a washing machine and cost $88 million to build and launch. While part of its mission is to spot polluters, the other side of the coin is that it can verify that others are indeed managing those emissions in a responsible fashion. Stemming methane leaks is the fastest single way to curb the escalation of average global temperatures, according to The Guardian.

Cancer vaccine for dogs almost doubles survival rates in clinical trial

Scientists at Yale University adapted existing human cancer treatments to find a new version that could benefit both humans and dogs. After conducting multiple clinical trials involving over 300 dogs over the past eight years, the researchers say that their canine cancer vaccine has almost doubled the 12-month survival rate for dogs with some types of cancer.

Scientists invent ultrathin, wireless, light-operated pacemaker that cuts invasive surgery

Scientists at the University of Chicago have developed a new pacemaker that’s thinner than a human hair, wireless, and operated entirely by light from an optic fiber. The non-invasive device could help regulate heart activity or even stimulate neurons in a set pattern to treat symptoms of conditions like Parkinson’s.

Belgian boy becomes first child in the world to be cured of brain stem glioma

Brain stem glioma, officially called diffuse intrinsic pontine glioma (DIPG), is rare and lethal, diagnosed in just 300 children annually in the United States. The two-year survival rate is 10%, and no drug is widely available for its treatment beyond radiotherapy. After the boy’s diagnosis, the family traveled to France to take part in a randomized controlled trial. He was randomly assigned the drug everolimus, which he took for more than 5 years with remarkable success.

Solar panels

Turkish scientists develop “bumpy” solar panel concept that can harvest up to 66% more energy

Solar cell efficiency may get a bump from bumps. New research from Turkey’s Abdullah Gül University suggests that building tiny domes into the surface of organic solar cells could boost their efficiency by up to two-thirds, while capturing light from a wider angle.

Dentist's Hand Taking Saliva Test From Woman's Mouth

Hand-held test for breast cancer uses your saliva and gives accurate readings in 5 seconds

A new hand-held portable device is not only extremely quick and easy to use but very cost effective, say scientists from the University of Florida and National Yang Ming Chiao Tung University in Taiwan. Compared to the costly alternatives of Mammograms, which expose women to radiation—or MRIs and ultrasounds which require expensive equipment—researchers called the device revolutionary.
