Why do antidepressants take so long to kick in?
Posted by Shubham Ghosh Roy in categories: biotech/medical, neuroscience
Have you ever wondered why SSRIs take time to show effects? A new study has delved into why antidepressants like SSRIs take weeks to start working and how this may impact mental health care.
SSRIs, or Selective Serotonin Reuptake Inhibitors, belong to a category of antidepressant drugs designed to elevate serotonin levels in the brain. Notable examples of SSRIs include fluoxetine (Prozac), sertraline (Zoloft), and escitalopram (Lexapro).

Scientists unveil blueprint for affordable solar cells to power Saudi Arabia and beyond
Posted by Raphael Ramos in categories: solar power, sustainability
Scientists have unveiled a roadmap for bringing perovskite/silicon tandem solar cells to market, paving the way for a future powered by abundant, inexpensive clean energy in Saudi Arabia and the world.
The authors of the article, published in Science, include Prof. Stefaan De Wolf and his research team at King Abdullah University of Science (KAUST) and Technology Solar Center. The team is working on improving solar efficiency to meet Saudi Arabia’ solar targets.
Perovskite/silicon tandem technology combines the strengths of two materials— perovskite’s efficient light absorption and silicon’s long-term stability—to achieve record-breaking efficiency. In 2023, the De Wolf laboratory reported two world records for power conversion efficiency, with five achieved globally in the same year, showing rapid progress in perovskite/silicon tandem technology.

Scientists find ‘key’ to potential breast cancer prevention and treatment
Posted by Genevieve Klien in category: biotech/medical
Every time a cancer cell divides, it sustains damage to its own DNA molecules. Researchers, including Gaorav Gupta, MD, Ph.D., associate professor in the Department of Radiation Oncology at the UNC School of Medicine, have long wondered how cancers are able to evade detection by the body’s own defenses, despite the immune system being on constant watch for cells displaying DNA damage.

COSMIC: The SETI Institute is Unlocking the Mysteries of the Universe with Breakthrough Technology at the Karl G. Jansky Very Large Array
Posted by Dan Breeden in categories: alien life, innovation
January 8, 2024, Mountain View, CA — In a groundbreaking cosmic quest, the SETI Institute’s Commensal Open-Source Multimode Interferometer Cluster (COSMIC) at the Karl G. Jansky Very Large Array (VLA) is expanding the search for extraterrestrial intelligence (SETI). This cutting-edge technology is not a distinct telescope; it’s a detector. COSMIC searches for extraterrestrial signals and paves the way for future science using a copy of the raw data from the telescope’s observations. At the heart of COSMIC’s mission is pursuing the age-old question: Are we alone in the universe? Project scientist Dr. Chenoa Tremblay and the team detailed the project in a paper published in The Astronomical Journal.
What sets COSMIC apart is its adaptability to the future. The system is designed for future upgrades, ensuring it remains at the forefront of cosmic exploration. With the potential to expand its capabilities, COSMIC could soon cover more stars, explore new frequencies, and enhance our understanding of the vast cosmic tapestry. It is important to note that COSMIC’s capabilities go beyond searching for extraterrestrial intelligence. Future upgrades could unlock new explorations, from finding fast radio bursts with a submillisecond temporal resolution to studying spectral line science and axionic dark matter.
“COSMIC introduces modern Ethernet-based digital architecture on the VLA, allowing for a test bed for future technologies as we move into the next generation era,” said Tremblay. “Currently, the focus is on creating one of the largest surveys for technological signals, with over 500,000 sources observed in the first six months. However, the flexibility of the design allows for a wide range of other scientific opportunities, such as studying fast radio burst pulse structures and searching for axion dark matter candidates. We hope to open opportunities for other scientists to use our high time (nanoseconds) or our high spectral resolution (sub-Hz) to complete their research. It is an exciting time for increasing the capabilities of this historic telescope.”
