When fatigued individuals perceive a task as being achievable and worth doing, they increase their effort to make up for their diminished capability due to fatigue. As a result, blood pressure tends to rise and remain elevated until the task is completed or individuals stop trying because they think success is impossible or too difficult to be justified.

Chemical fingerprints of volcanic eruptions and numerous pumice lump finds from archaeological excavations illustrate relations between individual advanced civilizations in the Eastern Mediterranean. Thanks to new tests and to the provenancing of the respective pumice samples to partially far-reaching volcanic eruptions, it became possible to redefine a piece of cultural history from the second millenium B.C.

Scientists have developed a mathematical model to describe interactions that occur within genetic networks of an embryo, answering the age-old question of how half embryos are able to maintain their tissues and organs in the correct proportions despite being smaller than a normal sized embryo. Understanding the processes that govern embryonic cell development, may lead, in the future, to scientists being able to repair injured tissues.

Researchers have captured time-series snapshots of a solid as it evolves on the ultra-fast timescale. Using femtosecond X-ray free electron laser (FEL) pulses, the team is able to observe condensed phase dynamics such as crack formation, phase separation, rapid fluctuations in the liquid state or in biologically relevant environments.
