• Yawning — why is it so contagious and why should it matter?

    Feeling tired? Even if we aren’t tired, why do we yawn if someone else does? Experts at the University of Nottingham have published research that suggests the human propensity for contagious yawning is triggered automatically by primitive reflexes in the primary motor cortex — an area of the brain responsible for motor function.

  • USGS Crews Measure Record Flooding in South-Central Texas

    As of this morning, 57 USGS streamgages are over National Weather Service flood levels, and water continues to rise at 118 gauges throughout Texas.  

    Seventeen USGS field crews are measuring high flood flows and verifying streamgage operations on the Colorado, Brazos, San Jacinto and Trinity River basins. Preliminary data show record high flood levels were measured at 16 locations throughout the greater Houston area. Accessing specific locations has proved challenging due to road closures and many sites being flooded at levels too dangerous to measure at this time.

  • Robotic system monitors specific neurons

    Recording electrical signals from inside a neuron in the living brain can reveal a great deal of information about that neuron’s function and how it coordinates with other cells in the brain. However, performing this kind of recording is extremely difficult, so only a handful of neuroscience labs around the world do it.

    To make this technique more widely available, MIT engineers have now devised a way to automate the process, using a computer algorithm that analyzes microscope images and guides a robotic arm to the target cell.

  • GPM Satellite Sees Tropical Storm Irma Forming Near Cape Verde Islands

    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.

  • 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.

  • 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.
