Lessons From Astronomy and Biology for the Mind—Copernican Revolution in Neuroscience

open access: yesFrontiers in Human Neuroscience, 2019
Neuroscience made major progress in unravelling the neural basis of mental features like self, consciousness, affect, etc. However, we nevertheless lack what recently has been described as “missing ingredient” or “common currency” in the relationship ...

Realistic Sensitivity Curves For Pulsar Timing Arrays [PDF]

open access: yes, 2019
We construct realistic sensitivity curves for pulsar timing array searches for gravitational waves, incorporating both red and white noise contributions to individual pulsar noise spectra, and the effect of fitting to a pulsar timing model.

Bioengineering facets of the tumor microenvironment in 3D tumor models: insights into cellular, biophysical and biochemical interactions

open access: yesFEBS Open Bio, EarlyView.
The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

Chandra X-Ray Spectroscopy Of The Very Early O Supergiant HD 93129A: Constraints On Wind Shocks And The Mass-Loss Rate [PDF]

open access: yes, 2011
We present an analysis of both the resolved X-ray emission-line profiles and the broad-band X-ray spectrum of the O-2 If* star HD 93129A, measured with the Chandra High Energy Transmission Grating Spectrometer ( HETGS).

Possible role of human ribonuclease dicer in the regulation of R loops

open access: yesFEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

What do we expect, as teachers, when selecting a text for our students: comprehension or readability? [PDF]

open access: yesInvestigações em Ensino de Ciências, 1999
This paper analyzes the role that a group of college teachers of physics assigns to the comprehension of instructions and of concepts. Based on a text fragment, used to trigger answers, we discuss the "forms" that are attributed to the comprehension of ...
