av Glucocorticoids Rapidly Modulate CaV1.2-Mediated Calcium Signals through Kv2.1 Channel Clusters in Hippocampal Neurons By www.jneurosci.org Published On :: 2024-11-06T09:30:07-08:00 The precise regulation of Ca2+ signals plays a crucial role in the physiological functions of neurons. Here, we investigated the rapid effect of glucocorticoids on Ca2+ signals in cultured hippocampal neurons from both female and male rats. In cultured hippocampal neurons, glucocorticoids inhibited the spontaneous somatic Ca2+ spikes generated by Kv2.1-organized Ca2+ microdomains. Furthermore, glucocorticoids rapidly reduced the cell surface expressions of Kv2.1 and CaV1.2 channels in hippocampal neurons. In HEK293 cells transfected with Kv2.1 alone, glucocorticoids significantly reduced the surface expression of Kv2.1 with little effect on K+ currents. In HEK293 cells transfected with CaV1.2 alone, glucocorticoids inhibited CaV1.2 currents but had no effect on the cell surface expression of CaV1.2. Notably, in the presence of wild-type Kv2.1, glucocorticoids caused a decrease in the surface expression of CaV1.2 channels in HEK293 cells. However, this effect was not observed in the presence of nonclustering Kv2.1S586A mutant channels. Live-cell imaging showed that glucocorticoids rapidly decreased Kv2.1 clusters on the plasma membrane. Correspondingly, Western blot results indicated a significant increase in the cytoplasmic level of Kv2.1, suggesting the endocytosis of Kv2.1 clusters. Glucocorticoids rapidly decreased the intracellular cAMP concentration and the phosphorylation level of PKA in hippocampal neurons. The PKA inhibitor H89 mimicked the effect of glucocorticoids on Kv2.1, while the PKA agonist forskolin abrogated the effect. In conclusion, glucocorticoids rapidly suppress CaV1.2-mediated Ca2+ signals in hippocampal neurons by promoting the endocytosis of Kv2.1 channel clusters through reducing PKA activity. Full Article

av Meet the Team of Scientists Who Discovered Gravitational Waves By www.smithsonianmag.com Published On :: Thu, 31 Oct 2024 00:00:00 -0000 Kip Thorne, Rainer Weiss, Barry Barish and Ronald Drever | Smithsonian Magazine’s 2016 American Ingenuity Award Winners for Physical Sciences In February, physicists announced the first-ever detection of gravitational waves—a phenomenon Albert Einstein predicted back in 1915. The faint reverberation, from two merging black holes 1.3 billion light-years ago, registered in the two giant detectors that make up the Laser Interferometer Gravitational-Wave Observatory, or LIGO. It took decades for LIGO’s founders—Weiss, of MIT, and Thorne and Drever, of Cal Tech—to amass the necessary funding and brainpower. Barish, a particle physicist at CalTech, became LIGO’s director and expanded its work to include more than 1,000 researchers worldwide. Their revolutionary achievement opens the way for a new understanding of the universe, perhaps even a glimpse of the Big Bang.

av As Hurricanes Get Stronger, Can a $34 Billion Plan Save Texas? By www.smithsonianmag.com Published On :: Thu, 31 Oct 2024 00:00:00 -0000 After Hurricane Ike destroyed thousands of homes and inflicted an estimated $30 billion in damages in 2008, engineers hatched an ambitious plan to protect southeast Texas and its coastal refineries and shipping routes from violent storms. The $34 billion collaboration spearheaded by the U.S. Army Corps of Engineers is a harbinger of the type of massive public works projects that could be required to protect coastal cities like New York and Miami as sea levels rise and hurricanes become less predictable and more severe due to climate change. Smithsonian magazine contributor and Texas native Xander Peters reflects on his experiences growing up in a hurricane corridor and tells us how the wildly ambitious effort came together. Then, Eric Sanderson, an ecological historian, tells us how the project could be applied to other low-lying coastal cities.

av America’s Best New Restaurant Celebrates the Flavors of West Africa By www.smithsonianmag.com Published On :: Thu, 31 Oct 2024 00:00:00 -0000 African cuisine has always been well represented in the United States, particularly in dishes characterized as “Southern” in origin, like gumbo or hoppin’ john. But even before chef Serigne Mbaye’s New Orleans eatery Dakar NOLA was named (https://www.eater.com/24175309/james-beard-awards-2024-winners-restaurant-and-chef-awards) the Best New Restaurant of 2024 at the James Beard Awards this week, the contributions of the African diaspora to the American diet had at last begun to enjoy a long-overdue reappraisal via reality television, Netflix docuseries and, most important, a number of widely praised dining establishments: If you want to book a table at Tatiana (https://www.tatiananyc.com/story/) in Manhattan, Dept of Culture (https://www.deptofculturebk.com/) in Brooklyn or Kann (https://kannrestaurant.com/) in Portland, you’d better plan ahead, because their tables are often booked up well in advance. In this episode, Smithsonian contributor Rosalind Cummings-Yeates explains how the ascendancy of pan-African cuisine from “auntie” restaurants into the rarefied fine dining sphere is part of a larger and more meaningful campaign of cultural reclamation. And Mbaye tells us why it was so important to him to make Dakar NOLA (https://www.dakarnola.com/) a showcase of the distinctive flavors of Senegal, where he spent his formative years.

Walters, a Flint resident, grew suspicious when her tap water changed color and her family suffered odd maladies. Officials insisted that the problems were limited to her household, but she refused to accept that answer and sought out Edwards, a Virginia Tech civil engineering professor and a veteran of municipal water wars. Combining political action and scientific credibility, the testing initiative undertaken by Walters and Edwards showed that the city’s water supply was contaminated with toxic chemicals—an explosive finding that finally forced state and local officials to address the dangers.

Over the past decade, the David Lynch Foundation has sponsored Transcendental Meditation classes for half a million children in places as far-flung as the Bronx, Detroit, Los Angeles, Congo and the West Bank. The program, called Quiet Time, is now at the center of one of the largest-ever studies of meditation for children—a 6,800-pupil research project conducted by the Crime Lab at the University of Chicago and designed to learn if meditation can help kids in highly stressful environments fare better at home and in school.
