A system made with two inexpensive sensors proves to be more accurate than smartwatches for measuring calories burned during activity – and the instructions for making the system yourself are available for free online.
Combining economics, psychology and studies of fertilizer application, researchers find that plants nearly follow an “equal pay for equal work” rule when giving resources to partner microbes – except when those microbes underperform.
Researchers created an algorithm to identify similar cell types from species – including fish, mice, flatworms and sponges – that have diverged for hundreds of millions of years, which could help fill in gaps in our understanding of evolution.
A fossil study from Stanford University finds the diversity of life in the world’s oceans declined time and again over the past 145 million years during periods of extreme warming. Temperatures that make it hard for cold-blooded sea creatures to breathe have likely been among the biggest drivers for shifts in the distribution of marine biodiversity.
Researchers examined 14,000 genetic differences between modern humans and our most recent ancestors at a new level of detail. They found that differences in gene activation – not just genetic code – could underlie evolution of the brain and vocal tract.
Science outreach efforts can encourage trust and interest in science, benefiting everyone involved. A guide produced by plant biologists from several institutions aims to make science outreach better and more effective.
North Pacific loggerhead turtles’ years-long oceanic journeys remain poorly understood. Using data from satellite tracking and other techniques, scientists reveal a unique phenomenon that may explain the endangered migrants’ pathway.
Stanford biologists have built a model examining the relationship between physical traits and genetic ancestry in populations formed from the mixture of multiple founding groups. They found that the relationship dissipates over generations.
