Solar plane lands in New York City

A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said.  The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website.  Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015. The solar cr...

HIV-infected organs transplant success

In total, two kidneys and two livers were donated after death to seriously ill people who also had the virus.  NHS transplant experts said the breakthrough would help reduce the shortage of donor organs and they hoped more people with HIV would join the organ donor register.  About three people a day die waiting for an organ transplant.  Prof John Forsythe, associate medical director for organ donation and transplantation at NHS Blood and Transplant, said: "It's exciting that some people with HIV in the UK have helped benefit patients with HIV after their death by donating their organs.  "While organ transplants from donors with HIV are limited to recipients with HIV infection, innovations like this open up the possibility of donation where it did not previously exist and will help to reduce the shortage of donor organs." At present, organs from donors with HIV can only be donated to people who also have the HIV infection.  All potential donors are test...

A gene-editing method can make pig organs suitable for use in people, scientists say

Prof George Church and colleagues used a technique called Crispr to alter the DNA of pig cells to create a better match for humans.  The early work, in the journal Science, aims to address concerns about rejection and infection by viruses embedded in pig DNA.  If successful, it could be an answer to the shortage of human donor organs.  Years more research is needed before genetically modified pigs could be bred to grow organs for people. Gene editing Crispr is a relatively new scientific tool that lets scientists snip and  play around with the code of life - DNA.  Prof Church, from Harvard University, used it to inactivate a retrovirus present in the pig cell line.This porcine endogenous retrovirus is potentially risky because it can infect human cells - at least in the lab.  In tests on early pig embryos, Prof Church was able to eliminate all 62 copies of porcine endogenous retroviruses from the pig cells using Crispr.  Next, he checked i...
