Alexander Hamilton, Benjamin Franklin, Hubert Humphrey and some guy named “Thomas Moore” are among the names that many Americans mistakenly identify as belonging to a past president of the United States, finds a news study by memory researchers at Washington University in St. Louis.
Anthropologists from Washington University in St. Louis are among an international research team that found Australopithecus sediba did not have the jaw and tooth structure necessary to exist on a steady diet of hard foods. The findings are contrary to a 2012 study that gained international attention.
An upcoming broadcast of NOVA called “Memory Hackers,” airs Wednesday, Feb. 10, and will explore the cutting edge frontiers of human memory. Washington University in St. Louis scientists are featured in the show.
Why was the New Year’s flood in Missouri so bad? Most news reports blamed it on the heavy rain, but Robert Criss, PhD, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis says analysis of the flood data shows much of the damage was due to recent modifications to the river.
Engineers at Washington University in St. Louis use nanoparticle technology, applied to a drug found in most people’s medicine cabinets, to chemically alter a cancer tumor and stop its growth.
Given that antibiotics are losing effectiveness faster than we are finding replacements for them, chemist Timothy Wencewicz in Arts & Sciences at Washington University in St. Louis suggests a new approach. Drugs that hobble the production of virulence factors — small molecules that help bacteria to establish an infection in a host — would put much less selective pressure on bacteria and delay resistance.
Genes inherited from mothers (matrigenes) and fathers (patrigenes) usually work harmoniously in the offspring. However, kin selection theory predicts these genes may be in conflict in interactions among relatives in which they are unequally represented (half-siblings). In honey bees, patrigenes are predicted to favor daughters that lay eggs themselves rather than remaining sterile and rearing their half-sisters’ offspring. An experimental test bears out this prediction.
Even before they can read, children as young as three years of age are beginning to understand how a written word is different than a simple drawing — a nuance that could provide an important early indicator for children who may need extra help with reading lessons, suggests new research from Washington University in St. Louis.
Curious seismologists who looked at the recordings made by a seismic station four miles away from the “cook-off” of an ammunition holding area in Iraq in 2006 found they could distinguish, mortars, rockets, improvised explosive devices, helicopters and drones. Seismology is increasingly being used for investigative purposes, they said, not just to detect earthquakes.
The Moon was never a fully homogenized body like Earth, analysis of Moon rocks made by the Chinese rover, Yutu, suggests. The basalts the rover examined are a new type, chemically different from those retrieved by the Apollo and Luna missions 40 years ago.
