Tatum Fettig remembers when her family's lives changed forever. In 2016, her daughter Teagan began vomiting and struggling with balance. At Seattle Children's, Teagan, then 2, was diagnosed with a pediatric brain tumor, medulloblastoma. Through the grueling process of chemotherapy treatment and radiation, Fettig and her husband were by Teagan's side, trying to cope with the uncertainty of whether they would see their youngest child grow up. They mourned the loss of their former life.
About 466 million years ago, long before the age of the dinosaurs, the Earth froze. The seas began to ice over at the Earth's poles, and the new range of temperatures around the planet set the stage for a boom of new species evolving. The cause of this ice age was a mystery, until now: a new study in Science Advances argues that the ice age was caused by global cooling, triggered by extra dust in the atmosphere from a giant asteroid collision in outer space.
Redesigning molecules originally developed to treat the skin disease psoriasis could lead to an effective new drug against malaria, according to an international team of researchers. The team modified a class of molecules called pantothenamides to increase their stability in humans. The new compounds stop the malaria parasite from replicating in infected humans and from being transmitted to mosquitos, and are effective against malaria parasites resistant to currently available drugs.
Thick, impenetrable ice slabs are expanding rapidly on the interior of Greenland's ice sheet, where the ice is normally porous and able to reabsorb meltwater. These slabs are instead sending meltwater spilling into the ocean, according to a new CIRES-led assessment, threatening to increase the country's contribution to sea level rise by as much as 2.9 inches by 2100.
Scientists say bolder actions to protect coral reefs from the effects of global warming will benefit all ecosystems, including those on land.
In an article published in Nature today two researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU) say the world's reefs will disappear by 2070 if climate change continues on its current path. Even well-protected World Heritage-listed coral reefs have been increasingly damaged by regional and global bleaching since 1980.
Sea urchins have five teeth, each held by a separate jaw in a circular arrangement at the center of their spiked, spherical bodies. Now, researchers reporting in the journal Matter on September 18 have discovered how the teeth of the pink sea urchin are specially equipped to sharpen themselves.
As the global demand for tissue and organ transplants significantly outstrips supply, tissue engineering might provide a potential solution. But one of the significant challenges in tissue engineering is growing tissue in 3D, and the scaffolds used to position cells to develop tissue-specific functions are often challenging or prohibitively expensive to develop.
Bottom Line: A study of nine emergency department residents reports inconsistencies between the electronic medical record and physicians' behaviors observed and recorded during patient encounters. Resident physicians were shadowed by trained observers for 20 encounters in this study conducted at emergency departments in two academic medical centers. The study quantified the review of systems (when patients are asked questions about different organs) and physical examinations documented by physicians and what observers confirmed.
What The Study Did: National survey data helped the authors of this study examine how common it is for U.S. hospitals and physician practices to screen patients for social needs such as food insecurity, housing instability, utility and transportation needs, and experience with interpersonal violence.

Tit for tat, do unto others, one good turn deserves another. These are only some of the familiar expressions which articulate the belief that reciprocity is a basic principle of social interactions. Developmental psychologists Monika Wörle and Professor Markus Paulus have now asked whether and when children learn to regard reciprocity as a norm. The notion of reciprocity is fundamental to many types of social interaction and serves to stabilize social relations.
Data centers are processing data and dispensing the results at astonishing rates and such robust systems require a significant amount of energy -- so much energy, in fact, that information communication technology is projected to account for 20% of total energy consumption in the United States by 2020.
To answer this demand, a team of researchers from Japan and the United States have developed a framework to reduce energy consumption while improving efficiency.
They published their results on July 19 in Scientific Reports, a Nature journal.
CHAPEL HILL, NC - September 18, 2019 - A marijuana plant extract, also known as cannabidiol (CBD), is being commonly used to improve anxiety, sleep problems, pain, and many other neurological conditions. Now UNC School of Medicine researchers show it may alleviate seizures and normalize brain rhythms in Angelman syndrome, a rare neurodevelopmental condition.
It sounds like science fiction: controlling electronic devices with brain waves. But researchers have developed a new type of electroencephalogram (EEG) electrode that can do just that, without the sticky gel required for conventional electrodes. Even better, the devices work through a full head of hair. The researchers report the flexible electrodes, which could someday be used in brain-computer interfaces to drive cars or move artificial limbs, in the ACS journal Nano Letters.
LAWRENCE -- A new study in the Journal of Neurophysiology by researchers at the University of Kansas Life Span Institute is the first to look at functional brain activity in people with autism spectrum disorder (ASD) while they performed precision visuomotor behavior -- in this case, a grip-force test.
Nature has evolved a dazzling array of materials that help organisms thrive in diverse habitats. Sometimes, scientists can exploit these designs to develop useful materials with similar or completely new functions. Now, researchers reporting in ACS Applied Materials & Interfaces have made a durable and flexible super-water-repelling material inspired by spiky porcupinefish skin.
