Hurricane Maria had a significant impact on HIV care outcomes

Thu, 07/03/2019 - 16:31
Hurricane Maria in San Juan, Puerto Rico had a significant impact on HIV outcomes among people living with HIV and a history of substance use, particularly increased viral load and decreased CD4 counts. The average viral load following the Hurricane was significantly (11 percent) higher compared to the pre-Hurricane Maria viral load assessment.

How bacteria can help prevent coal ash spills

Researchers have developed a technique that uses bacteria to produce 'biocement' in coal ash ponds, making the coal ash easier to store and limiting the risk of coal ash spills into surface waters.

In disasters, Twitter influencers get out-tweeted

Wed, 13/02/2019 - 20:26
A first-of-its-kind study on Twitter use during 5 of the costliest US natural disasters offers potentially life-saving insights. The research finds that Twitter users with small networks (100-200 followers) increase activity more than those with larger networks in these situations. It also finds that each disaster type (hurricanes, tornadoes, floods) has a unique pattern of social media use. The results have important implications for government and organizations responsible for emergency preparations.

Landslides triggered by Hurricane Maria

Thu, 07/02/2019 - 16:26
Hurricane Maria hit the island of Puerto Rico on 20 September 2017 and triggered more than 40,000 landslides in at least three-fourths of Puerto Rico's 78 municipalities. Researchers write that 'the number of landslides that occurred during this event was two orders of magnitude greater than those reported from previous hurricanes.'

Hurricane Katrina's aftermath included spike in heart disease hospitalizations

Thu, 31/01/2019 - 16:49
Hospitalizations for cardiovascular disease rose precipitously in Orleans and Jefferson parishes after Hurricane Katrina. The increase in rates lasted for more than one month after landfall and rates were higher among the older black population, compared to the older white population.

Possible Oahu populations offer new hope for Hawaiian seabirds

Tue, 22/01/2019 - 14:43
The two seabird species unique to Hawaii, Newell's shearwaters and Hawaiian petrels, are the focus of major conservation efforts -- at risk from habitat degradation, invasive predators, and other threats, their populations plummeted 94 percent and 78 percent respectively between 1993 and 2013. However, a new study offers hope of previously undetected colonies of these birds on the island of Oahu, from which they were believed to have vanished by the late 1700s.

Hurricane Maria gave ecologists rare chance to study how tropical dry forests recover

Tue, 18/12/2018 - 13:47
To counteract the damage hurricanes have caused to their canopies, trees appear to adjust key characteristics of their newly grown leaves, according to a year-long field study.

Unexpected impact of hurricanes on Puerto Rico's watershed

Mon, 10/12/2018 - 17:57
Researchers have found unprecedentedly high levels of nitrate, an essential plant nutrient, in streams and watersheds of Puerto Rico for a year after two consecutive major hurricanes in 2017. This high amount of nitrate may have important climate change implications that could harm forest recovery and threaten ecosystems along Puerto Rico's coastline by escalating algal blooms and dead zones.
