Flexible diet may help leaf-eating lemurs resist deforestation

Apr 23 2021 - 00:04
A new study sequencing the genome of four species of sifakas (Propithecus), a genus of lemurs found in Madagascar's forests, reveals that these animals' taste for leaves runs all the way to their genes, which are also more diverse than expected for an endangered species. But they can also thrive on fruit and flowers, which may be an advantage over being strictly leaves-only or fruit-only in the face of forest fragmentation.

Successful cancer therapy using artificial metalloenzymes to deliver drugs

Apr 23 2021 - 00:04
Researchers led by Katsunori Tanaka and Kenward Vong at the RIKEN Cluster for Pioneering Research (CPR) in Japan have combined cancer therapy drugs with a cancer cell-selective delivery system made from an artificial enzyme. The system reduced tumor onset and growth in mice.

High school junior's consumer seismometer delivers low-cost earthquake early warning

Apr 23 2021 - 00:04
A Southern California high school junior has built a low-cost seismometer device that delivers earthquake early warnings for homes and businesses. Costing less than $100 for her to make today, the seismometer could someday be a regular household safety device akin to a smart smoke detector.

Response options should be at the center of climate risk assessment and management

Apr 23 2021 - 00:04
A team of researchers from the Africa Climate and Development Initiative (ACDI) led a global team of 21 climate risk scholars to better understand and inform decision making around climate change risks in Africa and globally by examining how the drivers of risk interact. Their work extends on existing risk frameworks with the hope that this research could help decision makers, managers and researchers understand the inherent complexity of climate change.

Gauging groundwater

Apr 23 2021 - 00:04
"Jack and Jill went up the hill to fetch a pail of water." It's a silly rhyme, but one that highlights a simple fact: Humans have long relied on wells -- such as the one on the hill visited by Jack and Jill -- for their primary drinking water supply.

Skeletal defects may be ameliorated after immobility in the womb

Apr 23 2021 - 00:04
Researchers from Trinity College Dublin have discovered that some skeletal defects associated with a lack of movement in the womb during early development may still be ameliorated after such periods of immobility if movement resumes. The discovery was made using chicken embryos, which develop similarly to their human equivalents and which can be easily viewed as development takes place - raising hopes that the finding may also apply to humans and thus have important implications for therapeutic interventions.

Research shows pain relieving effects of CBD

Apr 23 2021 - 00:04
In the first experimental pain study of CBD in humans, researchers led by Syracuse University's Martin De Vita and Stephen Maisto conclude that CBD pain relief is driven by both pharmacological action and psychological placebo effects. The research is published in the American Psychological Association's Journal of Experimental and Clinical Psychopharmacology.

Defense mechanisms in aphids can become a double-edged sword, sharpened by the seasons

Apr 23 2021 - 00:04
In a newly published study in Molecular Ecology a team of Drexel University scientists examined the biological variations in pea aphids, insects that reproduce frequently enough to evolve before our eyes, by tracing the prevalence of their protective endosymbiont, Hamiltonella defensa, which the insects use to ward off parasitoid wasps.

Comprehensive NICU discharge planning essential for at-home readiness

Apr 23 2021 - 00:04
Being a parent of a Neonatal Intensive Care Unit (NICU) infant does not come with its own playbook of instructions. Preparing to care for a medically needy infant requires the mastery of technical skills, knowledge, emotional comfort and confidence. After confirming that an infant is medically ready for discharge, the quality of NICU discharge training/teaching is the strongest predictor of discharge readiness. A new study reinforces the importance of discharge preparation and transition to home planning.
