Schizosaccharomyces pombe yeast cells dividing. A multi-disciplinary team of scientists at Lehigh University and the University of Lausanne discover and characterize a new mechanism by which the fission yeast cell acquires its tubular shape. Working with light to activate processes within genetically modified fission yeast cells is among the research performed by the experimental biologists in the Martin Lab at the University of Lausanne, led by faculty member Sophie Martin. Team members there were conducting such experiments when they noticed that a certain protein, when introduced into the cell, would become displaced from the cell growth region. So, they reached out to Dimitrios Vavylonis, who leads the Vavylonis Group in the Department of Physics at Lehigh University, to find out why. “We proceeded to make a computational simulation that coupled cell membrane ‘growth’ to protein motion as well as model a few other hypotheses that we considered after discussions with them,” says Vavylonis, a theoretical physicist. This multidisciplinary collaboration combined modeling and experiments to describe a previously-unknown biological process. The teams discovered and characterized a new mechanism that a simple yeast cell uses to acquire its shape. They describe these results in a paper called “Cell patterning by secretion-induced plasma membrane flows” in a recent issue of Science Advances.

Proteins (green) with low mobility couple to the flows and are depleted from the secretion zone. Credit: Lehigh University and University of Lausanne When cells move or grow, they must add new membrane to those growth regions, says Vavylonis. The process of membrane delivery is called exocytosis. Cells also must deliver this membrane to a specific location in order to maintain a sense of direction-called “polarization”-or grow in a coordinated manner. “We demonstrated that these processes are coupled: local excess of exocytosis causes some of the proteins attached to the membrane to move (‘flow’) away from the growth region,” says Vavylonis. “These proteins that move away mark the non-growing cell region, thus establishing a self-sustaining pattern, which gives rise to the tubular shape of these yeast cells.” This is the first time that this mechanism for cell patterning-the process by which cells acquire spatial nonuniformities on their surfaces-has been identified. The Vavylonis team’s simulations, spearheaded by Postdoctoral Associate David Rutkowski, led to experimental tests which the Martin group then performed. Vavylonis and Rutkowski analyzed the results of the experiments to confirm that the distribution of proteins they noticed in their simulations matched the data gleaned from the experiments on live cells. The team says that the work could be of particular interest to researchers investigating processes that relate to cell growth and membrane traffic such as neurobiologists and those studying cancer cell processes. “Our work shows that patterns in biological systems are generally not static,” says Rutkowski. “Patterns establish themselves through physical processes involving continuous flow and turnover.” “We were able to provide support for the model of patterning by membrane-flow,” said Vavylonis. “In the end, the Martin group was able to use this knowledge to engineer cells whose shape can be controlled by light.” Reference: “Cell patterning by secretion-induced plasma membrane flows” by Veneta Gerganova, Iker Lamas, David M.

Sahas Barve, a Peter Buck Fellow at the Smithsonian’s National Museum of Natural History, led a new study to examine feathers across 249 species of Himalayan songbirds, finding that birds living at higher elevations have more of the fluffy down — the type of feathers humans stuff their jackets with — than birds from lower elevations. Published on February 15 in the journal Ecography, the study also finds that smaller-bodied birds, which lose heat faster than larger birds, tend to have longer feathers in proportion to their body size and thus a thicker layer of insulation. Credit: Suniti Bhushan Datta Study of Himalayan songbirds in museum collections is first step toward using feathers to predict the effects of climate change for birds in extreme environments. Feathers are a sleek, intricate evolutionary innovation that makes flight possible for birds, but in addition to their stiff, aerodynamic feathers used for flight, birds also keep a layer of soft, fluffy down feathers between their bodies and their outermost feathers to regulate body temperature. Using the Smithsonian’s collection of 625,000 bird specimens, Sahas Barve, a Peter Buck Fellow at the Smithsonian’s National Museum of Natural History, led a new study to examine feathers across 249 species of Himalayan songbirds, finding that birds living at higher elevations have more of the fluffy down — the type of feathers humans stuff their jackets with — than birds from lower elevations.

Credit: Chip Clark, Smithsonian How Down Feathers Keep Birds Warm Finding such a clear pattern across so many species underscores how important feathers are to a bird’s ability to adapt to its environment and suggests that adding down may be a strategy common to all songbirds, or passerines as they are known to researchers. Furthermore, finding that birds from colder environments tend to have more down may one day help researchers predict which birds are most vulnerable to climate change simply by studying their feathers. “The Himalayas are seeing some of the fastest rates of warming on Earth,” Barve said. “At the same time, climate change is driving an increase in the frequency and intensity of extremely cold events like snowstorms. Being able to accurately predict the temperatures a bird can withstand could give us a new tool to predict how certain species might respond to climate change.” The research was inspired by a tiny bird called goldcrest during a frigid morning of field work in the Sho-kharkh forest of the Himalayas. Barve found himself wondering how this bird, which weighs about the same as a teaspoon of sugar, was able to flit about the treetops in icy air that was already numbing his fingers. Shoving his hands back into the pockets of his thick down jacket, the question that formed in Barve’s mind was “Do Himalayan birds wear down jackets?” Barve led a new study to examine feathers across 249 species of Himalayan songbirds, finding that birds living at higher elevations have more of the fluffy down — the type of feathers humans stuff their jackets with — than birds from lower elevations.

Shoving his hands back into the pockets of his thick down jacket, the question that formed in Barve’s mind was “Do Himalayan birds wear down jackets?” Credit: Jennifer Renteria To answer that question, Barve and his co-authors used a microscope to take photos of the chest feathers of 1,715 specimens from the Smithsonian’s collections representing 249 species from the cold, high-altitude Himalayan Mountains. Then, Barve and his co-authors used those super-detailed photos to determine exactly how long each feather’s downy section was relative to its total length. The team was able to do that by looking at the fluffy downy section of each feather close to its base when compared to the streamlined ends of most birds’ feathers. After meticulously logging the relative lengths of all those downy sections, Barve analyzed the results and found that the smallest birds and the birds from the highest elevations, where temperatures are at their coldest, tended to have the highest proportion of down on their body feathers. The analysis showed that high-elevation birds had up to 25% more down in their feathers, and the smallest bird had feathers that were three times as long as the largest birds, proportionately to their body size. Wider Implications for Evolution and Climate Change Past research suggested that birds from colder habitats sported added downy insulation, but Barve said this is the first study to analyze this pattern for such a large number of species in cold environments and across 15,000 feet of elevation. “Seeing this correlation across so many species makes our findings more general and lets us say these results suggest all passerine birds may show this pattern,” Barve said. “And we never would have been able to look at so many different species and get at this more general pattern of evolution without the Smithsonian’s collections.” Carla Dove, who runs the museum’s Feather Identification Lab and contributed to the study, said she was excited to work together with Barve to use the Smithsonian’s collections in a new way. “Sahas looked at more than 1,700 specimens. Having them all in one place in downtown Washington, D.C., as opposed to having to go to the Himalayas and study these birds in the wild, obviously makes a big difference. It allowed him to gather the data he needed quickly before the COVID-19 lockdowns swept the globe, and then work on the analysis remotely.” Barve said he is following up this study with experiments looking into just how much insulation birds get from their feathers and then will tie that to the feather’s structure and proportion of down. One day, Barve aims to develop a model that will allow scientists to look at the structure of a feather and predict how much insulation it gives the bird–a capability that could help researchers identify species vulnerable to climate change. Dove said the potential to use these results to eventually understand how some birds might cope with climate change highlights the importance of museum collections. “We have more than 620,000 bird specimens collected over the past 200 years waiting for studies like this. We don’t know what our specimens will be used for down the line; that’s why we have to maintain them and keep enhancing them. These specimens from the past can be used to predict the future.” Reference: “Elevation and body size drive convergent variation in thermo‐insulative feather structure of Himalayan birds” by Sahas Barve, Vijay Ramesh, Toni M.

The findings may reshape our understanding of gene regulation and cellular precision. Silke Hauf and her research team made a surprisingly quiet discovery during their study on cell division. They observed that the expression of RNA in cells is always accompanied by a certain level of variability, or noise, in the amount of RNA produced. Interestingly, Hauf and her team identified multiple genes that exhibited fluctuations in noise that fell below a previously defined limit, referred to as the noise floor, during their expression. “We have solid data for this phenomenon,” said Hauf, associate professor in the Department of Biological Sciences at Virginia Tech. “There are some genes that are different and can have super low noise.” Often upstaged by the more striking, well-publicized high-noise genes, Hauf and her team were intrigued by these ultra-low noise genes as they provide a window into the understanding of gene expression and gene expression noise. This discovery, recently published in the journal Science Advances, includes contributions from co-authors Abhyudai Singh, professor of electrical and computer engineering at the University of Delaware, and Ramon Grima, professor of computational biology at the University of Edinburgh. Both Singh and Grima are also mathematical biologists.

Cells can’t avoid making noise, but for them to function well, the noise needs to be minimized. She compared it with airports attempting to keep their flights on time in order to gain maximum functionality.“So it’s exciting to see that there are genes that operate with a minimum level of noise,” said Hauf. “Imagine there was a flight that always left within five minutes of the scheduled departure time. Wouldn’t you want to know how the airline does it?” Opens the door to more discoveries Hauf is excited about understanding how these cells express in such a quiet manner and learning more about the mechanisms behind them. She also would like to find other genes in this category. “We saw these minimal fluctuations in one particular organism and cell type, but we really need to check other cells to determine if it is universal,” Hauf said.
