BIRMINGHAM, Ala. - Patients with chronic myeloid leukemia can be treated with tyrosine kinase inhibitors. While these effective drugs lead to deep remission and prolonged survival, primitive leukemia stem cells resist elimination during the remission and persist as a major barrier to cure.
Switchgrass is attractive as a potential bioenergy crop because it can grow for years without having to be replanted. Requiring less fertilizer than typical annual crops like corn, switchgrass can keep more nitrogen, phosphorus and carbon in the soil and out of our air and waterways. But, unlike corn, breeding of switchgrass for optimal traits is still in its early stages.
As if they were bubbles expanding in a just-opened bottle of champagne, tiny circular regions of magnetism can be rapidly enlarged to provide a precise method of measuring the magnetic properties of nanoparticles.
A scorpion native to Eastern Mexico may have more than just toxin in its sting. Researchers at Stanford University and in Mexico have found that the venom also contains two color-changing compounds that could help fight bacterial infections.
The team not only isolated the compounds in the scorpion's venom, but also synthesized them in the lab and verified that the lab-made versions killed staphylococcus and drug-resistant tuberculosis bacteria in tissue samples and in mice.
The cooling of the Southern Ocean surrounding Antarctica, which began approximately 35 million years ago and gave rise to its present icy state, has for decades been considered a classic example of climate change triggering rapid adaptation.
Using tens of thousands of genes mapped from across the genomes of a group of Antarctic fishes called notothenioids, a team of researchers is now challenging this paradigm, revealing that the massive amount of genetic change required for life in the Antarctic occurred long before the Antarctic cooled.
Recordings of neural activity during therapeutic stimulation can be used to predict subsequent changes in brain connectivity, according to a study of epilepsy patients published in JNeurosci. This approach could inform efforts to improve brain stimulation treatments for depression and other psychiatric disorders.
A grape variety still used in wine production in France today can be traced back 900 years to just one ancestral plant, scientists have discovered.
With the help of an extensive genetic database of modern grapevines, researchers were able to test and compare 28 archaeological seeds from French sites dating back to the Iron Age, Roman era, and medieval period.
Trichoplax is one of the simplest animals one can imagine, and looks like a shapeless little blob. Senior author Nicole Dubilier says it reminds her of a potato chip. Trichoplax lives in warm coastal waters around the world, where it grazes on microscopic algae that cover sand and rocks. Although most aquarists may not know it, Trichoplax can also be found in almost any saltwater aquarium with corals.
ANN ARBOR--If astronomers want to learn about how supermassive black holes form, they have to start small--really small, astronomically speaking.
In fact, a team including University of Michigan astronomer Elena Gallo has discovered that a black hole at the center of a nearby dwarf galaxy, called NGC 4395, is about 40 times smaller than previously thought. Their findings are published in the journal Nature Astronomy.
Firearm injuries kill more American children and teens than anything else, except automobile crashes. But research on how those injuries happen, who's most likely to suffer or die from one, or what steps would prevent them, has lagged behind research on other causes of death in young people.
Meanwhile, firearm deaths among people age 19 and under have grown 44 percent since 2013.
