Spaceflight alters DNA of astronauts’ blood Blood samples collected from all 14 astronauts who traveled to space as part of NASA’s space shuttle program between 1998 and 2001 showed evidence of DNA mutations after being stored for 20 years. While the mutations are below a key threshold for concern, researchers suggest astronauts submit to periodic […]

The dominant role of many-body correlations in TMDs superconductivity

The dominant role of many-body correlations in TMDs superconductivity

DIPC Advanced materialsDIPC Interfaces

By DIPC

Several classes of correlated electron systems such as cuprates, iron-pnictides, iron-chalcogenides, and several heavy-fermion compounds, have been identified as unconventional superconductors. More recently, superconductivity with unconventional features has also been identified in twisted bilayer graphene. In this vein, the electronic correlations intrinsically present in transition metal dichalcogenides (TMDs), a family of layered materials, are promising […]

Intermittent fasting could improve nerve regeneration

Intermittent fasting could improve nerve regeneration

Molecular biologyNeuroscience

By Rosa García-Verdugo

Intermittent fasting is more than the latest diet fad, it has proven benefits –at least in animal models– against longevity, and it appears that it could even improve nerve regeneration, according to new research. The problems with axons in the peripheral nervous system is that their regenerative capacity is not very high. There are certain […]

Social networks and risk behaviors of adolescents and young adults

Social networks and risk behaviors of adolescents and young adults

Sociology

By Invited Researcher

Social networks and digital platforms allow adolescents to interact with each other and to develop and maintain positive interpersonal relationships and support networks that are critical in their development. In general, teens benefit from socialization opportunities such as keeping in touch, sharing images, or interchanging ideas. In addition, social networking encourages participation, creative expression, and […]

Blazars draw power from black holes High-energy particles such as neutrinos and cosmic rays that pummel the Earth from the depths of space originate in actively galactic nuclei fueled by giant black holes, known as blazars. “The discovery of the connection between these objects and the cosmic rays may be the ‘Rosetta stone’ of high-energy […]

Spoof surface plasmons

Spoof surface plasmons

DIPCDIPC Photonics

By DIPC

When the surface of a perfect conductor is structured at a length scale much smaller than the operating wavelength, geometrically induced surface electromagnetic modes can be supported. Owing to their similarities with the surface plasmon polaritons in the optical regime, these surface electromagnetic modes were named spoof surface plasmons. A new review provides a detailed […]

Modelling the new neuron-glial paradigm

Modelling the new neuron-glial paradigm

MathematicsNeuroscience

By BCAM

Modelling of neuron-glial interactions is an emerging field of Computational Neuroscience. The ubiquity of these interactions and the possibility that they may occur within the time and spatial scales that are usually ascribed to neuronal and synaptic function, calls for a revision of current neuron-based modeling paradigms to include potentially relevant effects mediated by glial […]

The bigger the temperature change, the larger the extinction event

The bigger the temperature change, the larger the extinction event

Geosciences

By César Tomé

New research has unearthed evidence that points to a strong relationship between the magnitude of mass extinctions and global temperature changes in geologic times. Abrupt climate change, accompanied by environmental destruction from large volcanic eruptions and meteorites, has caused major mass extinctions throughout the Phanerozoic Eon, covering 539 million years to the present. To date […]
