Neu entdecktes Protein arbeitete schon in den allerersten Organismen

Wissenschaftler stoßen auf neuen Baustein eines Zellprozesses: Das cAMP Rezeptor Protein SbtB kontrolliert den Kohlendioxid-Stoffwechsel in Cyanobakterien

Leben auf der Erde wird erst durch die sogenannte CO2 Fixierung während der Photosynthese möglich: Pflanzen nehmen Kohlenstoffdioxid auf und verwandeln es in organische Moleküle wie z.B. Glucose. Dieser Prozess entstand vor über 2,7 Milliarden Jahren in der Organismengruppe der Cyanobakterien, die diese Fähigkeit später auf das Reich der Algen und Pflanzen ausdehnten. (more…)

Study reveals reversibility of Friedreich’s ataxia in mice

UCLA researchers are able to turn on and off the genetic defect that causes the disease

Friedreich’s ataxia is an inherited disease that causes damage to the nervous system and a loss of coordination that typically progresses to muscle weakness. It can begin causing symptoms in childhood or early adulthood and, over time, it can also lead to vision loss and diabetes. (more…)

Auf der Suche nach der Dunklen Materie bestimmen Physiker stärkste Grenze für die kaum messbaren „WIMP“-Partikel

Kosmologische Beobachtungen zeigen, dass das Universum zum großen Teil aus Dunkler Materie besteht. Was diese ausmacht, ist allerdings bislang unbekannt. Physikalische Theorien sagen voraus, dass es sich bei den Dunkle-Materie-Teilchen um so genannte WIMPs (weakly interacting massive particles) handeln könnte. (more…)

What happens when the water rises?

Q&A with DGS officials provides insight into sea level rise

Societal concerns about climate change, severe weather and rising seas are raising questions about readiness across the globe. Extreme weather events this year such as Hurricanes Harvey, Irma and Maria underscore the need to be prepared. (more…)

Video game system technology helping physical therapists, athletic trainers

New studies from MU researchers provide evidence that video game technology can help health care providers discover injury risk and track rehabilitation progress among athletes, patients

COLUMBIA, Mo. – Motion-based lab technology can help physical therapists, clinicians and athletic trainers analyze how we move—it also is very expensive. Some motion labs can cost upward of $100,000. Now, a team of University of Missouri researchers is finding that the depth camera often associated with video game systems can provide a variety of health care providers with objective information to improve patient care.

Research reveals the scale at which Earth’s mantle composition varies

A new study by geochemists from Brown University suggests that Earth’s mantle varies in composition over kilometer-sized pockets.

PROVIDENCE, R.I. [Brown University] — New research by Brown University geochemists provides new insights on the scale at which Earth’s mantle varies in chemical composition. The findings could help scientists better understand the mixing process of mantle convection, the slow churning that drives the movement of Earth’s tectonic plates. (more…)
