Sulfonium cations for quasi-2D perovskite solar cells
Ruddlesden-Popper-type (RP) quasi-two-dimensional (2D) perovskite solar cells (PSCs) have attracted extensive attention due to their unique photovoltaic properties and excellent device stability. Due to disordered crystallization, the film quality of.....»»
As EV sales slump, Volkswagen scales back battery factories buildout
VW might only need 170 GWh of cells in 2030 if demand stays depressed. Enlarge / A VW worker on the assembly line at Emden in Germany. (credit: Volkswagen) Volkswagen will wait to see what electric car demand is like be.....»»
Scientists propose guidelines for solar geoengineering research
Scientists for several years have studied the theoretical effectiveness of injecting sulfur dioxide into the stratosphere to reflect heat from the sun and offset Earth's warming temperatures. But they also want to ensure that the solar geoengineering.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Single nucleosomes tracked in live cells during cell division using super-resolution microscopy
Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poor.....»»
The secret to sleepy cells" control of inflammatory secretions
Scientists at Sanford Burnham Prebys and the La Jolla Institute for Immunology have revealed a new secret regarding senescence, a cellular state similar to sleep that is more likely to affect aged cells. This drowsy condition is known to provide heal.....»»
Novel silica nonwoven fabric scaffold enhances understanding of cell-to-cell interactions
Communication and coordination among different cells are fundamental aspects that regulate many functions in our body. This process, known as paracrine signaling, involves the release of signaling molecules by a cell into its extracellular matrix (EC.....»»
Tissue fluidization during skin repair is crucial for wound healing, study reveals
The ability to repair tissue following injuries is essential for the survival of all animals. Following wounding, the skin is repaired by activating, migrating, and dividing skin stem cells. Defects of wound healing in humans lead to chronic wounds t.....»»
Surprising mechanism for removing dead cells identified
Billions of our cells die every day to make way for the growth of new ones. Most of these goners are cleaned up by phagocytes—mobile immune cells that migrate where needed to engulf problematic substances. But some dying or dead cells are consumed.....»»
Unveiling the hottest period in a million years: The MIS 11c paradox
The hottest warm period in the past million years is believed to have occurred about 400,000 years ago. During this time, the Northern Hemisphere had less ice than today, and sea levels were about 10 meters higher. Surprisingly, solar radiation, a ke.....»»
Astronomers discover spectacular increase in the deuterium to hydrogen ratio in Venus"s atmosphere
Thanks to observations by the Solar Occultation in the Infrared (SOIR) instrument on the Venus Express space probe of the European Space Agency (ESA), researchers have discovered an unexpected increase in the abundances of two water molecule variants.....»»
New forensics technique measures individual DNA shedding to aid criminal investigations
A pioneering new DNA forensics technique is looking for a reliable method to measure a suspect's individual level of natural shedding of skin and other cells to add to, and compare with, evidence collected at crime scenes......»»
Green light for accurate vegetation research: Evaluation of global SIF datasets
A recent study has pinpointed the top-performing solar-induced chlorophyll fluorescence (SIF) products for precise global monitoring of photosynthesis and vegetation dynamics. By thoroughly evaluating eight widely-used SIF datasets, the research team.....»»
Sea anemone study identifies potentially regenerative stem cells linked to conserved genes
The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists led by Ulrich Technau from the University of Vienna have now identified possible candidates for multipotent stem cells in the se.....»»
Project Helianthus—a solar-sail-driven geomagnetic storm tracker
Solar storms captured the imagination of much of the American public earlier this year when auroras were visible well south of their typical northern areas. As the sun ramps into another solar cycle, those storms will become more and more common, and.....»»
New method uses nanoparticles to reprogram exhausted immune cells
A novel study led by Prof. Mira Barda-Saad and her research team at the Goodman Faculty of Life Sciences at Bar-Ilan University has unveiled a novel method to rejuvenate natural killer (NK) cells in the fight against cancer. The study, published on t.....»»
Going slow is better for fast cycling: Study reveals unique replication fork behavior in pluripotent stem cells
Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic replication stress. However, a recent report published in E.....»»
Exploring Huntington"s disease: Researchers discover that protein aggregates poke holes in the nuclear membrane
Researchers at Utrecht University in the Netherlands have identified a new way in which the toxic protein aggregates associated with Huntington's disease may damage nerve cells and cause them to die......»»
New tool simplifies cell tracking data analysis
Studying cell migration is vital because it plays a crucial role in many biological processes, including immune response, wound healing, and cancer metastasis. Understanding how cells move and behave can lead to breakthroughs in treating diseases, de.....»»
GM signs 15-year solar energy deal that will power 3 U.S. plants
