Using Facebook to help young adults quit smoking  

A national clinical trial testing a smoking cessation intervention for young adults that was conducted entirely on Facebook has found that smokers are 2.5 times more likely to quit after three months with the Facebook-based treatment than if they were referred to an online quit-smoking program.

Reconstructing Zika's spread  

The urgent threat from Zika virus, which dominated headlines in early 2016, has passed. But research into how Zika and other mosquito-borne infections spread and cause epidemics is still very active. Researchers now report new details of how Zika emerged from Brazil and spread throughout Mexico and Central America, with evidence that some locations had more than one outbreak.

Imminent extinction of northern white rhinoceros motivates genetic recovery efforts  

Earlier this year, the last remaining male northern white rhinoceros (NWR) died in captivity, nearly cementing the fate of this subspecies for extinction. In the wild, continuing threats of poaching, habitat destruction, and small population size have contributed to the rhinos' status as critically endangered. Yet, novel conservation efforts that make use of cryopreserved genetic material could save the NWR, and other threatened species, from extinction.

New theory finds 'traffic jams' in jet stream cause abnormal weather patterns  

A study offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it's exceeded, blockages form that are remarkably similar to traffic jams -- and climate forecasters can use the same math to model them both.

Cancer cells co-opt pain-sensing 'wasabi receptor' to survive oxidative stress  

Some cancers express unusually high levels of a neural calcium channel known as the 'wasabi receptor,' which plays a role in detecting pain, cold and other sensations. New research finds cancer cells co-opt this neural channel to increase their tolerance against toxic oxidative stress. Blocking the activity of this channel in mice curbs tumor growth and makes cancer cells more sensitive to chemotherapy.

Adding the effects of the chemicals to a predisposition for Parkinson's disease drastically increases the risk of disease onset.

Cold production of new seafloor  

Magma steadily emerges between oceanic plates. It pushes the plates apart, builds large underwater mountains and forms new seafloor.
