Hormones not the only drivers of sex disparities in heart health

Often when it comes to disease, the sexes are not equal. Dementia, chronic kidney disease, and many other conditions disproportionately affect one sex or another. Heart disease is a complex case: Males are more likely to suffer heart attacks at … Continue reading

When listeners pay close attention to stories, their heart rates synchronize

  An international team of researchers has shown that when a group of people hear the same story or watch the same video, their heart rates tend to rise and fall in synch. This correlation of heart rates, described this … Continue reading

Drought causes lasting changes to the rice root microbiome

Beneficial microbes living in and around a crop’s roots could be powerful allies in the fight to keep plants alive through droughts, especially as climate change worsens. But before scientists can harness these microbial partners to make crops more resilient, … Continue reading

Emotional associations, more than knowledge, determine how much people care about the deep sea

With new technological advances in deep-sea mining, the ocean floor’s trove of valuable metals and rare earth elements is coming within reach of commercial mining operations. The impending reality of this practice, and its associated environmental risks, raises the question … Continue reading

Transgenic switchgrass cleans up contamination from military explosives

At military sites in the United States and across the globe, routine live-fire trainings produce a downpour of an explosive known as RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine). A synthetic chemical, RDX can threaten human health, damaging the nervous system if inhaled or ingested. … Continue reading

Heavy water tastes sweeter

In the 1930s, scientists discovered a heavier form of water. So-called “heavy water” (D2O) weighs more because the nucleus of each of its two hydrogen atoms contains not just a proton but a neutron as well. Known as deuterium, heavy … Continue reading

Agricultural spray could quickly deliver advantageous genes to crops mid-growing season

Plant breeders are masters of genome tuning, spending years developing crops with the genes to resist disease, drought, and pests. Now, a team of industry and academic researchers in Germany and the United Kingdom has developed a viral vector technology … Continue reading

Smaller salamander species associated with smaller genomes

The world’s tiniest salamanders are so small that some body parts appear to get short shrift. Those in the genus Thorius, for example, have heads that are “mind bogglingly small, maybe half the size of a pencil eraser,” says herpetologist … Continue reading

Model suggests how evolution shapes ecological networks among species

The natural world is filled with networks. Predator and prey, flower and pollinator—each interacting pair forms a link in a networked community of organisms. Now, a French research team has developed a model that explores how evolution may help shape … Continue reading

In plea for face masks, researchers visualize how speech sends fluid droplets flying

As COVID-19 ravaged Wuhan, China, in January, scientists remained unsure how the virus was spreading so rapidly. Biophysicist Adriaan Bax, chatting over dinner with his linguist wife Ingrid Pufahl, started to suspect that the saliva we project as we speak … Continue reading

Fluid dynamics work hints at whether spoken word can spread COVID-19

As of April 3, the Centers for Disease Control and Prevention (CDC) is advising that everyone—sick or healthy—wear masks to prevent the spread of COVID-19. Recent research on how fluids travel from our respiratory tracts when we sneeze, speak, or … Continue reading
