Spike in available transplant organs has been due to opioid deaths, study finds.

Increase in available transplant organs tied to opioid deaths

"We want doctors to not fear taking organs from this source," say researchers. Donor organs for transplants are in high demand. It’s estimated that 20 people die each day waiting for a transplant in the United States. But the chances for patients on the waiting list are also improving, as rates...

The study in which researchers synthesized a smallpox relative from scratch just got published in an open access journal, spelling out how a virologist ordered bits of horsepox DNA from the internet, assembled them, then showed that the resulting virus was able to infect cells and reproduce.

Construction of an infectious horsepox virus vaccine from chemically synthesized DNA fragments

Edward Jenner and his contemporaries believed that his variolae vaccinae originated in horses and molecular analyses show that modern vaccinia virus (VACV) strains share common ancestry with horsepox virus (HPXV). Given concerns relating to the toxicity of modern VACV vaccines, we asked whether an HPXV-based vaccine might provide a superior alternative. Since HPXV may be extinct and the only specimen of HPXV that has been identified is unavailable for investigation, we explored whether HPXV coul

New Nature study finds temperatures likely to rise about 8 C if carbon emissions go unchecked and the Earth's remaining fossil fuels are burned. It predicts increases as high as 17 C in the Arctic region.

Temperatures to rise about 8°C by 2300 if emissions are not mitigated, new Nature study finds

Increase could be as much as 17 °C in the Arctic. The study, published today in Nature Climate Change, uses complex Earth system models to simulate...
