Engineers are testing heated pavement technologies at the Des Moines International Airport. They've installed two test slabs of electrically conductive concrete. And the pavement has effectively cleared ice and snow.
When tilling soil, the blade of the tool cuts through dirt, loosening it in preparation for seeding. The dirt granules are pushed aside in a way that looks random -- but might not be. Now, researchers have found a way to distinguish whether such a process is truly random, or is actually deterministic -- which can lead to deeper understanding and the ability to control the process.
Women who pursue in vitro fertilization (IVF) to become pregnant are more likely to give birth if they have health insurance that covers the procedure, according to new research. The key reason is financial rather than medical: For many people, the high cost for one IVF procedure prohibits women from seeking a second treatment if the first attempt fails.
A fluorescent probe lights up the enzyme beta-galactosidase in a cell culture. The glowing probe-enzyme combination could make tumors fluoresce, allowing surgeons to cut away cancer while leaving healthy tissue intact.
Less than a third of men in a large national survey reported talking with their doctor about both the pros and cons of the PSA blood test for prostate cancer, and the likelihood has decreased further since a national panel recommended against the test.
The researchers conducted several demonstrations to transmit a message into computers connected to a flatbed scanner. Using direct laser light sources up to a half-mile (900 meters) away, as well as on a drone outside their office building, the researchers successfully sent a message to trigger malware through the scanner.
How can long DNA filaments, which have convoluted and highly knotted structure, manage to pass through the tiny pores of biological systems? Scientists used computer simulations to investigate the options available to the genetic material in such situations.
A new study finds that stimulating the cerebellum in rats with schizophrenia-like thinking problems normalizes brain activity in the frontal cortex and corrects the rats' ability to estimate the passage of time -- a cognitive deficit that is characteristic in people with schizophrenia.
Bioengineers have discovered a protein that regulates the switch of embryonic stem cells from the least developed 'naïve' state to the more developed 'primed' state. This discovery sheds light on stem cell development at a molecular level.
Using advanced modeling and simulation, seismic data generated by earthquakes, and one of the world's fastest supercomputers, a team of scientists is creating a detailed 3-D picture of Earth's interior. Currently, the team is focused on imaging the entire globe from the surface to the core-mantle boundary, a depth of 1,800 miles.
Older adults are powerful allies in addressing climate change, say researchers. Research shows that older adults are at risk for the effects of extreme weather events and climate change; but they are also a potential resource for climate action.
Targeting dementia in the earlier stages of the condition could be critical for the success of future therapies, say researchers who have found that the very earliest symptoms of dementia might be due to abnormal stability in brain cell connections rather than the death of brain tissue, which comes after.
Researchers found similar rates of disease-free survival and no difference in overall survival among women who received a laparoscopic or abdominal total hysterectomy for stage I endometrial cancer, according to a study.
Researchers have identified proteins that enable deadly malaria parasites to 'walk through cell walls' -- a superpower that was revealed using the Institute's first insectary to grow human malaria parasites. The research has identified two parasite proteins that are the key to this superpower. The proteins could be targeted to develop much-needed antimalarial drugs or vaccines.
A bacterial species that hunts other bacteria has attracted interest as a potential antibiotic, but exactly how this predator tracks down its prey has not been clear. A new study reveals that the bacterial predator Bdellovibrio bacteriovorus homes in on its target by taking advantage of fluid forces generated by its own swimming movements and those of its prey. These bring the bacteria in close proximity, giving BV a greater chance of successful attack.
While the search for elixir of life has captivated human imagination for millennia, researchers around the world have put in efforts to extend healthy lifespan and reduce the burden of morbid diseases in an increasingly aging population. Researchers have now identified a control mechanism within a longevity gene, which is key to unraveling its functional diversity and is likely to boost efforts at designing specific pharmacological agents.
Researchers have discovered drugs that activate signaling pathways leading to specific adult brain cell types from stem cells in the mouse brain, according to a new study. The results may open new avenues for drug development aimed at treatment of degenerative brain disorders.
