Philadelphia, September 22, 2020 - Researchers from Children's Hospital of Philadelphia (CHOP) have shown there may be key genetic differences in the causes of attention-deficit hyperactivity disorder (ADHD) between African Americans and people of European ancestry, which may play an important part in how patients of different ethnic backgrounds respond to treatments for this condition. The findings were published online by the journal Scientific Reports.
NASA's Aqua satellite analyzed Tropical Storm Beta in infrared imagery to determine where the strongest parts of the storm were located. Beta is expected to stall inland over Texas today, Sept. 21, and heavy rains will continue over portions of the middle and upper Texas coast.
Beta's center has continued to move farther inland since making landfall on the southern end of the Matagorda Peninsula around 11 p.m. EDT on Sept. 21.
Cheating mitochondria may take advantage of cellular mechanisms for coping with food scarcity in a simple worm to persist, even though this can reduce the worm's wellbeing.
These findings, published today in eLife, may help shed light on the evolution of cheating and cooperative behaviours within different organisms.
GAINESVILLE, Fla. --- Mushroom-munching bonobos in the Democratic Republic of the Congo have introduced scientists to a new species of truffle.
Commonly used by Congolese communities to bait traps for small mammals, Hysterangium bonobo is also savored by bonobos, an endangered species of great ape. Scientists say the truffle hints at vast reserves of undescribed fungal diversity in the region.
The sounds, the lights, the layout, even the smells of the Montreal Casino have all been carefully crafted to entice gamers inside, and to keep them there as long as possible.
Several coastal communities are picking up the pieces after being ravaged by hurricanes in the past month. Hurricane Laura, a category 4, and Hurricane Sally, a category 2, seemed to meander their way across the Gulf of Mexico constantly shifting forecasts and keeping meteorologists on their toes. In the hours before these storms struck land, they seemed to explode in intensity.
Researchers at the Dauphin Island Sea Lab with support from the Jet Propulsion Laboratory can offer insight into why these storms intensified quickly as they moved across the continental shelf.
NASA's Terra satellite obtained visible imagery of Tropical Storm Dolphin as it continued moving north though the Northwestern Pacific Ocean on a track toward east central Japan.

As Arctic summers warm, Earth's northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth.
Carnegie Mellon University's Maysam Chamanzar and his team have invented an optical platform that will likely become the new standard in optical biointerfaces. He's labeled this new field of optical technology "Parylene photonics," demonstrated in a recent paper in Nature Microsystems and Nanoengineering.
Muslims and atheists in the United States are more likely than those of Christian faiths to experience religious discrimination, according to new research led by the University of Washington.
In the study, which focused on public schools because they are government-run, community-facing institutions, the researchers tested responses to an individual’s expression of religious belief. In addition to finding greater bias against religious minorities, the researchers also saw that ardent expressions of faith, regardless of religious tradition, were more prone to discrimination.

As head of the educational outreach arm of the Florida State University-headquartered National High Magnetic Field Laboratory, Roxanne Hughes has overseen dozens of science camps over the years, including numerous sessions of the successful SciGirls Summer Camp she co-organizes with WFSU .
In a new paper published in the Journal of Research in Science Teaching, Hughes and her colleagues took a much closer look at one of those camps, a coding camp for middle school girls.
Throughout the late 19th century, rivers across the southwestern United States were parceled out, and flows were diverted through irrigation canals and trapped behind dams. Growing populations put new demands on groundwater sources. Coupled with changing climate conditions, water tables sank and perennial streams began to run dry.
The fate of the Santa Cruz River in southeastern Arizona was no different.
AUGUSTA, Ga. (September 22, 2020) - The kidneys often become bulky and dysfunctional in diabetes, and now scientists have found that one path to this damage dramatically reduces the kidney's ability to clean up after itself.
The natural cleanup is called autophagy, which literally means "self-eating," and it's a constant throughout our bodies as debris, like misfolded proteins and damaged cell powerhouses called mitochondria, get packaged into a double-membrane sack, then destroyed by enzymes to help keep cells and organs functioning at a premium.
A new Canadian study reveals that the psychological and physical effects of childhood sexual abuse are closely tied.
The finding could help healthcare professionals develop more effective interventions and ultimately improve mental and physical health outcomes for survivors of abuse in childhood.
Authored by Pascale Vézina-Gagnon, a PhD candidate at Université de Montréal's Department of Psychology, under the supervision of Professor Isabelle Daigneault, the study is published today in Health Psychology.
