Bone Marrow Protein May Be Target for Improving Stem Cell Transplants

and has no comments yet.
Bone marrow contains hematopoetic stem cells, the precursors to every blood cell type. These cells spring into action following bone marrow transplants, bone marrow injury and during systemic infection, creating new blood cells, including immune cells, in a process known as hematopoiesis.

Hunt is over for one of the 'Top 50 Most-Wanted Fungi'

and has no comments yet.
In a step toward bridging the gap between fungal taxonomy and molecular ecology, scientists from several institutions including Los Alamos National Laboratory have characterized a sample of “mystery” fungus collected in North Carolina and found its home in the fungal tree of life.

NASA Infrared Imagery Shows Wind Shear Affecting Tropical Storm Maria

and has no comments yet.
Tropical Storm Maria is now caught up in the Westerlies and is being affected by wind shear that is elongating the storm. Infrared imagery from NASA’s Aqua satellite revealed that Maria’s strongest storms were east of the tropical cyclone’s center because of westerly wind shear.

Antarctica: Return of the Weddell Polynya supports Kiel Climate Model

and has no comments yet.
Currently, winter has still a firm grip on Antarctica. At this time of the year, the Weddell Sea usually is covered with a thick layer of sea ice. In spite of the icy temperatures in the region, satellite images depict a large ice-free area in the middle of the ice cover. The area of the hole in the ice is larger than The Netherlands and it fascinates climate and polar researchers worldwide. Scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel are closely monitoring the developments. “For us this ice-free area is an important new data point which we can use to validate our climate models. Its occurrence after several decades also confirms our previous calculations," says Dr. Torge Martin, meteorologist and climate modeler in the GEOMAR Research Division "Oceans Circulation and Climate Dynamics".

Climate's Effects on Flowers Critical for Bumble Bees

and has no comments yet.
In a study that shows the importance of climate change on critical pollinators, North Carolina State University researchers found that earlier and longer flowering seasons can have poor effects on the bumble bees that rely on these flowers to live and thrive.

World-First Optical Fiber Laser Promises To Revolutionise Detection Of Gases

and has no comments yet.
An international research group, led by Macquarie University scientists, has developed a world-first optical fiber technology which can help detect a wide range of gases with unprecedented sensitivity, with potential applications ranging from breath analysis to air-quality monitoring. The discovery, which has been published in the journal Optica, outlines the development of an optical fiber device which encompasses an invisible infrared laser coupled to an ultra-broadband supercontinuum generator – two elements that researchers have never managed to combine to a single optical system before.

NASA Satellite Highlights Burn Scars in British Columbia

and has no comments yet.
This past summer Canada has been plagued with huge forest fires that have spanned most of the provinces.  British Columbia has been particularly hard hit with large portions of the landscape being decimated by fire.  In these satellite images taken by the NASA'S Aqua satellite, both the natural color and false color burn scars of left by fires can be seen.  In the natural color image it is difficult to make out the burn scars.  The false color easily identifies areas where fire has left a scar showing a brownish-red color. Currently there are 745 wildfires larger than 0.01 hectares and all wildfires of note (active or out) in British Columbia as of today, Sept. 29. (Wildfire link updates daily).  NASA's Aqua satellite collected this natural-color image with the Moderate Resolution Imaging Spectroradiometer, MODIS, instrument on September 27, 2017.

NASA Sees a Weaker Hurricane Lee Headed to the U.K.

and has no comments yet.
NASA and NOAA satellite imagery show Hurricane Lee has been on a weakening trend as wind shear is battering the storm. The National Hurricane Center expects Lee to weaken quickly and its remnants to bring gusty winds to Ireland and the United Kingdom over the weekend of Sept. 30 and Oct. 1.

Model predicts performance of glucose-responsive insulin

and has no comments yet.
People with Type 1 diabetes must check their blood glucose several times a day and inject themselves with insulin to keep their blood sugar levels within a healthy range. A better alternative, long sought by diabetes researchers, would be insulin that is engineered to linger in the bloodstream, becoming active only when needed, such as right after a meal.
