Volcanic Eruptions Drove Ancient Global Warming Event

Warming event that took place 56 million years ago led to significant ecological disruption and could shed light on modern climate change.

Machine-learning earthquake prediction in lab shows promise

A computer science approach using machine learning can predict the time remaining before the fault fails.

New robot rolls with the rules of pedestrian conduct

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.

NASA Sees Fourteenth Eastern Pacific Ocean Potential Tropical Cyclone

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.

Researchers tackle methane emissions with gas-guzzling bacteria

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.

Researchers Raise Public Health Concerns About Off-Road Vehicles and Inhalation of Asbestos

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.

NASA Shows How Harvey Saturated Areas in Texas

NASA analyzed the soil moisture in southeastern Texas before and after Harvey made landfall and found the ground was already somewhat saturated. NASA-NOAA’s Suomi NPP Satellite provided a night-time look at Harvey after it moved into the Gulf of Mexico, and NOAA’s GOES East satellite provided a look at the storm after it made its final landfall near the Texas-Louisiana border on Aug. 30.

New osteoporosis treatment uses traditional Chinese herb to prevent bone loss

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.

Tree's chemistry puts mountain pine beetle in sticky situation

A University of Alberta forestry professor has cracked a key mystery surrounding the mountain pine beetle.

After studying lodgepole pine trees in the Grande Prairie area that survived a pine beetle attack, U of A professor Nadir Erbilgin and his team discovered certain chemicals in the trees that produce high levels of resin—sticky sap—that overwhelms the insect.

Researchers discover new immunotherapy combination effective at killing cancer cells

Immunotherapy is an emerging field in the global fight against cancer, even though scientists and clinicians have been working for decades to find ways to help the body’s immune system detect and attack cancerous cells. Doug Mahoney’s lab at the University of Calgary recently discovered an immunotherapy that uses existing cancer drugs in a whole new way.
