Anesthetic drug sevoflurane improves sepsis outcomes, animal study reveals
Patients with sepsis often require surgery or imaging procedures under general anesthesia, yet there is no standard regimen for anesthetizing septic patients. Of volatile (inhaled) anesthetics, sevoflurane and isoflurane are the most commonly used drugs, despite their undetermined mechanisms of action. A novel study suggests that the type of drug used in general anesthesia could be critical to the survival of patients with sepsis.
Read moreExtinction of Icelandic walrus coincides with Norse settlement
An international collaboration of scientists has for the first time used ancient DNA analyses and C14-dating to demonstrate the past existence of a unique population of Icelandic walrus that went extinct shortly after Norse settlement some 1100 years ago. Walrus hunting and ivory trade was probably the principal cause of extinction, being one of the earliest examples of commercially driven overexploitation of marine resources.

Research shows disabled people face being marginalized by the very programs that are designed to help them. Projects and welfare systems established to provide support are normalizing disabled people, and unintentionally contributing to their further marginalization.

The sea-ice extent in the Arctic is nearing its annual minimum at the end of the melt season in September. Only circa 3.9 million square kilometers of the Arctic Ocean are covered by sea ice any more, according to researchers.
Read moreWaterhemp has evolved resistance to 4 herbicide sites of action
When a waterhemp biotype in eastern Nebraska survived a post-emergent application of the PPO inhibitor fomesafen, scientists decided to take a close look. They discovered the population was resistant to four distinct herbicide sites of action, including PPO inhibitors, ALS inhibitors, EPSPS inhibitors and PS II inhibitors.

For male Trinidad Guppies applies: if you are hungry, seek female company. A recent study provides evidence that male guppy fish in the presence of females more often ended up at novel food patches. In contrast, female food discovery was independent of male presence.
Read moreLH dipeptide may improve mental health
Researchers have made discoveries regarding the effect of the dipeptide Leucine-Histidine (LH) in suppressing microglial activation and depression-associated emotional disturbances. LH dipeptide is found in fermented foods such as blue cheese and natto (fermented soy beans). Foods rich in LH dipeptide may be a safe, preventive method for maintaining good mental health.
Read moreCancer cells prefer a 'comfort cruise,' follow predictable paths of least resistance
New research from biomedical engineers reveals that while cancer cells move quickly in metastasis, they're rather lazy in which paths they choose — opting to move through wider, easier to navigate spaces rather than smaller, confined spaces to reduce energy requirements during movement.
Read moreResearchers use light to control high-speed chemical reactions in a new way
Many natural and synthetic chemical systems react and change their properties in the presence of certain kinds of light. These reactions can occur too quickly for ordinary instruments to see. For the first time, researchers adopted a novel technique to observe the high-speed reactions. A special kind of reaction observed with this method could lead to new optical nanotechnology.
