Refuting the popular stereotype that females talk more than men, researchers at The University of Texas at Austin have found women and men both use an average of 16,000 words each day.
The psychology researchers have published their findings in “Are Women Really More Talkative Than Men"” in the July issue of Science.
For more than a decade, researchers have claimed that women use far more words each day than men. One set of numbers that is commonly tossed around is that women use 20,000 words per day compared to only 7,000 for men.
“These findings have been reported widely by national media and have entered the cultural mainstream,” James W. Pennebaker, chair of the Psychology Department and co-author of the study, said. “Although many people believe the stereotypes of females as talkative and males as reticent, there is no large-scale study that systematically has recorded the natural conversations of large groups of people for extended period of time.”
For eight years, the psychology researchers have developed a method for recording natural language using the electronically activated recorder (EAR). The unobtrusive digital voice recorder tracks people’s interactions, including their conversations.
The researchers analyzed the transcripts of almost 400 university students in the United States and Mexico whose daily interactions were recorded between 1998 and 2004. The research participants could not control the EAR, which automatically records for 30 seconds every 12.5 minutes, and did not know when the device was on.

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
