Die Ergebnisse beim Kolorektalkarzinom können sich durch eine genetische Veränderung eines immunregulatorischen Proteins in Krebszellen verbessern, durch welche die Zellen anfälliger für Chemotherapie werden. Das geht aus der neuen Studie der Mayo Clinic hervor.
Late in the prehistoric Silurian Period, around 420 million years ago, a devastating mass extinction event wiped 23 percent of all marine animals from the face of the planet. For years, scientists struggled to connect a mechanism to this mass extinction, one of the 10 most dramatic ever recorded in Earth’s history. Now, researchers from Florida State University have confirmed that this event, referred to by scientists as the Lau/Kozlowskii extinction, was triggered by an all-too-familiar culprit: rapid and widespread depletion of oxygen in the global oceans.

Analysis of calls to poison control centers by people misusing or abusing amphetamines, usually prescribed for ADHD, via IV injection, nasal or oral routes also links non-medical use to increased risk of admission to critical care units, attempted suicide and death.
Alcohol biosensors suitable for use by everyday drinkers are a step closer, following a positive study of prototype devices published in the journal Alcoholism: Clinical & Experimental Research. Keeping track of alcohol intake can be challenging, given variation in standard drink sizes and impaired awareness as blood alcohol levels rise. Discreet devices that track alcohol levels could help people make more informed decisions about when to stop drinking and could potentially reduce alcohol-related road deaths.
Mathematical modeling suggests that the diversity of interactions between species in an ecological community plays a greater role in maintaining community functioning than previously thought.

Before self-driving vehicles become a permanent fixture on our roads they need to overcome two challenges—figuring out where they are and their range of motion (localization) and modeling their surroundings to avoid running into stuff (mapping). In the world of robotics, it’s called SLAM—simultaneous localization and mapping. Researchers at the University of Delaware have developed novel SLAM algorithms that offer the best solution to date for giving these vehicles a sense of direction.
