The National Hurricane Center (NHC) upgraded a low pressure area in the far eastern Atlantic Ocean to tropical storm Irma on August 30, 2017 at 11 a.m. EDT (1500 UTC).
Tropical cyclones that form in that part of the Atlantic Ocean are often the largest and most powerful hurricanes of the season. Hurricanes Ivan (2004), Isabel (2003), Hugo (1989) and Allen (1980) are examples of past powerful hurricanes that formed near the Cape Verde islands.

When the Fukushima power plant released large quantities of radioactive materials into nearby coastal waters following Japan’s massive 2011 earthquake and tsunami, it raised concerns as to whether eating contaminated seafood might impair human health—not just locally but across the Pacific.
A new study by an international research team shows that those concerns can now be laid to rest, at least for consumption of meat from migratory marine predators such as tuna, swordfish, and sharks.

Just as drivers observe the rules of the road, most pedestrians follow certain social codes when navigating a hallway or a crowded thoroughfare: Keep to the right, pass on the left, maintain a respectable berth, and be ready to weave or change course to avoid oncoming obstacles while keeping up a steady walking pace.
Now engineers at MIT have designed an autonomous robot with “socially aware navigation,” that can keep pace with foot traffic while observing these general codes of pedestrian conduct.

Potential tropical cyclone 14E of the Eastern Pacific Ocean hurricane season appeared to be coming together off the southwestern coast of Mexico. NASA’s Aqua satellite captured temperature data on the storm that is producing torrential rains over southwestern Mexico.
Because of the large system’s proximity to land, it has spawned warnings and watches. A Hurricane Watch is in effect from Puerto Cortes to Los Barriles, Mexico. A Tropical Storm Warning is in effect for Todos Santos to Los Barriles, and a Tropical Storm Watch is in effect from north of Los Barriles to San Evaristo, Mexico.

An international research team co-led by a Monash biologist has shown that methane-oxidising bacteria – key organisms responsible for greenhouse gas mitigation – are more flexible and resilient than previously thought.
Soil bacteria that oxidise methane (methanotrophs) are globally important in capturing methane before it enters the atmosphere, and we now know that they can consume hydrogen gas to enhance their growth and survival.

Preventing injuries may not be the only reason children shouldn’t use off-road vehicles (ORVs).
In a new study, public health scientists raise concerns that people who use ORVs in many regions of the country may face exposure to hazardous mineral fibers. These include naturally occurring asbestos and erionite – an asbestos-like material that occurs in sedimentary rocks of the western United States.
Most of the deposits are located along the Appalachian Mountains and ranges in the West and Southwest, especially California.

An herb widely used in traditional Chinese medicine might hold the key to a new osteoporosis therapy that could prevent bone loss without causing side effects.
Using a compound derived from red sage, UBC researchers have found a way to selectively block an enzyme called Cathepsin K (CatK), which plays a major role in the breakdown of collagen in bones during osteoporosis. The findings were published in the Journal of Bone and Mineral Research.
