Cooling Mosquitoes’ Drive for Human Blood

Drawing from Smithsonian Magazine depicting mmosquitoes and thermonter

Anopheles gambiae mosquitoes use a receptor called IR21a to navigate toward warmth, a cue that signals they’re near food (Crystal Zhu, Garrity Lab, Brandeis University).

In a recent Science paper, the Garrity lab reported that they have found an important step in how mosquitoes sense human warmth. Once found, human blood becomes a food source for the insects’ eggs. Unfortunately,  mosquito bites have, over the centuries, spread disease and misery among humans.

The lab genetically modified mosquitoes to stop expressing a molecular thermostat called IR21a in their antennae. This reduced the insects’ ability to find the heat generated by humans. The hope is that this discovery will help remove the mosquitoes temperature sensors so they don’t spread disease. This discovery has also been summarized in the Smithsonian Magazine.

Goode, Gelles and Kondev labs synergize in discovery of a new synergistic actin depolymerization mechanism

All animal and plant cells contain a highly elaborate system of filamentous protein polymers called the actin cytoskeleton, a scaffold that can be rapidly transformed to alter a cell’s shape and function. A critical step in reconfiguring this scaffold is the rapid disassembly (or turnover) of the actin filaments. But how is this achieved? It has long been known that the protein Cofilin plays a central role in this process, but it has been unclear how Cofilin achieves this feat. Cofilin can sever actin filaments into smaller fragments to promote their disassembly, but whether it also catalyzes subunit dissociation from filament ends has remained uncertain and controversial. Until now, this problem has been difficult to address because of limitations in directly observing Cofilin’s biochemical effects at filament ends. However, a new study published in Nature Communications led by postdoctoral associate Dr. Shashank Shekhar, jointly mentored by Bruce Goode, Jeff Gelles and Jane Kondev, uses microfluidics-assisted single molecule TIRF imaging to tackle the problem.

The new study shows that Cofilin and one other protein (Srv2/CAP) intimately collaborate at one end of the actin filament to accelerate subunit dissociation by over 300-fold! These are the fastest rates of actin depolymerization ever observed. Further, these results establish a new paradigm in which a protein that decorates filament sides (Cofilin) works in concert with a protein that binds to filament ends (Srv2/CAP) to produce an activity that is orders of magnitude stronger than the that of either protein alone.

The work was funded by National Institutes of Health, National Science Foundation MRSEC and Simons Foundation grant.

MRSEC & RTI Hosts Science Outreach to Waltham Teachers

The Brandeis Materials Research Science and Engineering Center (MRSEC) and the Brandeis Research Technology and Innovation (or MakerLab) hosted a day of science and technology outreach on November 5, 2019. In the morning and for the fifth straight year, 23 Waltham High School Science teachers participated in a professional development workshop with 15 Brandeis scientists called, “Brandeis Scientists in the Classroom.” The teams of scientists and teachers visited laboratories and developed curriculum for the scientists to make future classroom visits to the High School to increase awareness of Brandeis science and to encourage WHS students to pursue STEM careers. In the afternoon, the teams were joined by more than 60 Brandeis students, staff and members of the greater community for a public event called, “Watch:City Science and Technology Forum.” This event celebrated Waltham and Brandeis as hubs of technology and discovery and promoted SciLinkR.com as a way to connect with professionals and promote science. There were short talks about public engagement with science by Waltham High School teachers Marisa Maddox and Ellen Stanton and by Brandeis scientists, Professor Avi Rodal, Dr. Anique Olivier-Mason, Dr. Vivek Vimal, and Raul Ramos. Participants also networked with each other during the poster session (20 posters by Brandeis scientists) and explored the gallery of Brandeis contributions to the Journal of Stories in Science. The organizers’ goal was for attendees to gain new perspectives in science and technology.

The event was sponsored by the Brandeis MRSEC, Research Technology & Innovation, Library, Hassenfeld Family Innovation Center, Nova BioMedical, AstraZeneca, and the New England Journal of Medicine.

Alumni and Student Researchers Wow Crowd at 2019 SciFest

With a new alumni symposium in the morning and a poster session filling three floors of the Science Center atrium in the afternoon, this year’s SciFest IX set a new standard for Brandeis Science’s annual celebration of undergraduate research.

Since 2011, a poster session featuring the results from ongoing projects belonging to undergraduates doing science research has been the high point of summer in the Division of Science at Brandeis. This year, for the first time, we invited Brandeis alumni scientists to speak in a morning symposium entitled “A Celebration of Brandeis’ Undergraduate Science Education”, including:

Students and faculty in the audience were treated to a history of Brandeis and reflections on many of the Brandeis professors and courses that set them on their career path and whose influence persists to the present in how they approach their science, and on lessons they learned that continue to guide their work.

After lunch in the campus center, the crowd climbed up to the Shapiro Science Center for the poster session. 123 students presented 117 posters on topics from high-energy physics to biomaterials and from quantum chemistry to fruit fly behavior. As President Ron Liebowitz noted in an email to the Science community after the event:

The energy in Shapiro during the poster session was electric.  The students’ confidence and excitement over sharing their research can only give us great optimism about the future: they are “all in” when it comes to doing basic research, but also seeing how such research can be applied in the name of helping others.

Many of the posters can be found in the hallway in Gerstenzang – look for them when classes start again in a few weeks!
