| Molecular design strategy reveals near infrared-absorbing hydrocarbon Posted: 17 Oct 2020 04:42 PM PDT The lessons learned from a near infrared absorbing, bowl-shaped molecule made only from hydrogen and carbon atoms offers insights for future organic conductors. |
| A controllable membrane to pull carbon dioxide out of exhaust streams Posted: 16 Oct 2020 11:58 AM PDT A system developed by chemical engineers could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively little energy. |
| Arctic Ocean sediments reveal permafrost thawing during past climate warming Posted: 16 Oct 2020 11:30 AM PDT Sea floor sediments of the Arctic Ocean can reveal how permafrost responds to climate warming. Researchers have found evidence of past permafrost thawing during climate warming events at the end of the last ice age. Their findings caution about what could happen in the near future: Arctic warming by only a few degrees Celsius may trigger massive permafrost thawing, coastal erosion, and the release of greenhouse gases. |
| Fats fighting back against bacteria Posted: 16 Oct 2020 11:30 AM PDT With antibiotic-resistant superbugs on the rise, this research shows a new way that cells are using to protect themselves - using fats as a covert weapon, and giving us new insights into alternative ways to fight infection. |
| Calcium bursts kill drug-resistant tumor cells Posted: 16 Oct 2020 10:20 AM PDT Multidrug resistance (MDR) -- a process in which tumors become resistant to multiple medicines -- is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that pump drugs out of the cell, rendering the chemotherapies ineffective. Now, researchers have developed nanoparticles that release bursts of calcium inside tumor cells, inhibiting drug pumps and reversing MDR. |
| Investigational ALS drug prolongs patient survival in clinical trial Posted: 16 Oct 2020 08:28 AM PDT An experimental medication that was recently shown to slow the progression of amyotrophic lateral sclerosis has now demonstrated the potential to also prolong patient survival. The findings come from a recent clinical trial. |
