Phys.org / The sex life of treefrogs: How females build better nests by mating with multiple partners
African gray foam-nest treefrogs (Chiromantis xerampelina) are common across the savannas and dry forests of southeastern Africa. Despite their unremarkable outward appearance, these small animals display some of the most ...
Phys.org / Exploring the lost golden age of language diversity before expanding empires drove a global decline
Today, people speak or sign around 7,500 languages. Yet this figure provides only a snapshot of a constantly changing history. How many languages existed before written records? Did agriculture reduce linguistic diversity ...
Medical Xpress / Blurred genome boundaries emerge as a new layer of Alzheimer's biology
Researchers from Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington have shed new light on Alzheimer's disease that could point to new ...
Phys.org / Ceramic vessels reveal how social inequalities were also cooked into 19th-century Brazil
Fish, shellfish, maize, manioc, rice and even chicken eggs. Molecular residues preserved in more than 180 ceramic vessels from southern Brazil have made it possible to reconstruct what different communities were cooking more ...
Phys.org / Shaking atoms to bring black-hole quantum chaos into the lab
Physicists have discovered a surprisingly simple way to reproduce one of the most fascinating models in modern physics—linked to black holes, quantum chaos and exotic electronic materials—using ultracold atoms trapped in ...
Phys.org / Simple circuit brings topological insulators closer to practical electrical measurement standards
Researchers at the University of Würzburg have succeeded in detecting exceptionally robust electrical transport in a topological insulator. This could lead to new metrological applications. The work is published in the journal ...
Medical Xpress / Premature blood stem cell aging in sickle cell disease may be reversible
Sickle cell disease causes premature aging of blood stem cells, which scientists may be able to address with a special class of drugs, according to a new study from St. Jude Children's Research Hospital. Patients with sickle ...
Phys.org / Alan Turing's gay short story reveals 'fun, cheeky' man who loved sex and literature
A startling new study of a little-known, unpublished short story by Alan Turing challenges our understanding of the man who played a key role in cracking the Nazis' Enigma code, developed the theoretical underpinnings of ...
Medical Xpress / Persistent money struggles tied to faster brain aging
Persistent financial hardship accelerates age-related cognitive decline, according to a new study led by University College London (UCL) researchers. The study, published in Innovation in Aging, looked at data from 2,759 ...
Phys.org / Peptide isolated from a Cerrado frog increases strawberry shelf life
Five minutes. That was the amount of time that Oso Grande strawberries remained in contact with the Ctx(Ile21)-Ha peptide—a molecule isolated from a frog native to the Brazilian Cerrado—in experiments conducted in Brazil ...
Medical Xpress / A mother's devotion to newborns begins in the brain, study suggests
New research has found that a hormone is responsible for making mothers' interactions with newborns feel rewarding rather than just necessary. The University of Otago—Ōtākou Whakaihu Waka study, published in Science Advances, ...
Medical Xpress / Two ways to read a genome: Body-wide, single-cell atlas maps DNA folding and methylation together
Every cell in the human body carries the same 3 billion letters of DNA, yet a neuron, a heart muscle cell and a pancreatic beta cell each use that shared code to do entirely different jobs. How cells pull off this trick comes ...
