A quick new way to screen virus...
A whole new world of antibiotics is waiting inside the viruses that infect bacteria. Scientists are making it easier to study them.
Researchers identify key gene controlling cadmium distribution...
Cadmium (Cd), a toxic heavy metal contaminant of cultivated land, is harmful to humans through its accumulation in crops, especially rice. Therefore, strategies to limit Cd accumulation in rice grains are urgently needed. In rice, Cd is taken up from the soil by the roots and then transported to tissues aboveground. The nodes, which are vascular bundles connected to the roots, leaves and panicles, play an important role in the redirection of Cd in rice.
Minke whales represent smallest size threshold that...
A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient “lunge-feeding” strategy that enabled the blue whale to become the largest animal on Earth.
3 Questions: Mriganka Sur on the research...
Rett syndrome is a devastating developmental disorder, principally occurring in girls, caused by mutations in the gene MECP2 that leads to severe cognitive, motor, and other symptoms. As such, the March 10 approval by the U.S. Food and Drug Administration of the first-ever treatment for the disorder, a drug called Trofinetide based on the natural protein IGF-1, brings new hope to patients and their families. The approval is also a dream come true for Mriganka Sur, Newton Professor of...
Triggering bitter taste receptors could someday treat...
Surprisingly, bitter taste receptors are not only located in the mouth, but also elsewhere in the body, including the airways. Activating those receptors opens up lung passageways, so they’re a potential target for treating asthma or chronic obstructive pulmonary disease (COPD). Now, researchers report that they have designed a potent and selective compound that could lead the way to such therapies.
New “traffic cop” algorithm helps a drone...
How fresh are your data? For drones searching a disaster zone or robots inspecting a building, working with the freshest data is key to locating a survivor or reporting a potential hazard. But when multiple robots simultaneously relay time-sensitive information over a wireless network, a traffic jam of data can ensue. Any information that gets through is too stale to consider as a useful, real-time report. Now, MIT engineers may have a solution. They’ve developed a method to tailor...
It’s a weird, weird quantum world
In 1994, as Professor Peter Shor PhD ’85 tells it, internal seminars at AT&T Bell Labs were lively affairs. The audience of physicists was an active and inquisitive bunch, often pelting speakers with questions throughout their talks. Shor, who worked at Bell Labs at the time, remembers several occasions when a speaker couldn’t get past their third slide, as they attempted to address a rapid line of questioning before their time was up. That year, when Shor took his...
Engaging enterprises with the climate crisis
Almost every large corporation is committed to achieving net zero carbon emissions by 2050 but lacks a roadmap to get there, says John Sterman, professor of management at MIT’s Sloan School of Management, co-director of the MIT Sloan Sustainability Initiative, and leader of its Climate Pathways Project. Sterman and colleagues offer a suite of well-honed strategies to smooth this journey, including a free global climate policy simulator called En-ROADS deployed in workshops that have educated more than 230,000 people,...
Shrinky Dinks, nail polish, and smelly bacteria
In a lab on the fourth floor of MIT’s Building 56, a group of Massachusetts high school students gathered around a device that measures conductivity. Vincent Nguyen, 15, from Saugus, thought of the times the material on their sample electrode flaked off the moment they took it out of the oven. Or how the electrode would fold weirdly onto itself. The big fails were kind of funny, but discouraging. The students had worked for a month, experimenting with different...
Celebrating a decade of a more sustainable...
When MIT’s Office of Sustainability (MITOS) first launched in 2013, it was charged with integrating sustainability across all levels of campus by engaging the collective brainpower of students, staff, faculty, alumni, and partners. At the eighth annual Sustainability Connect, MITOS’s signature event, held nearly a decade later, the room was filled with MIT community members representing 67 different departments, labs, and centers — demonstrating the breadth of engagement across MIT. Held on Feb. 14 and hosting more than 100...
How to assemble a complete jaw
The skeleton, tendons, and glands of a functional jaw all derive from the same population of stem cells, which arise from a cell population known as neural crest. To discover how these neural crest-derived cells know to make the right type of cell in the right location, researchers focused on a particular gene, Nr5a2, that was active in a region of the face that makes tendons and glands, but not skeleton. To understand the role of Nr5a2, the scientists...
Jewel beetles evolve to see new colors...
Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. New research investigated the complex evolutionary history of jewel beetles’ vision.
MIT professor to Congress: “We are at...
Government should not “abdicate” its responsibilities and leave the future path of artificial intelligence solely to Big Tech, Aleksander Mądry, the Cadence Design Systems Professor of Computing at MIT and director of the MIT Center for Deployable Machine Learning, told a Congressional panel on Wednesday. Rather, Mądry said, government should be asking questions about the purpose and explainability of the algorithms corporations are using, as a precursor to regulation, which he described as “an important tool” in ensuring that...
2023 MacVicar Faculty Fellows named
The Office of the Vice Chancellor and the Registrar’s Office have announced this year’s Margaret MacVicar Faculty Fellows: professor of brain and cognitive sciences John Gabrieli, associate professor of literature Marah Gubar, professor of biology Adam C. Martin, and associate professor of architecture Lawrence “Larry” Sass. For more than 30 years, the MacVicar Faculty Fellows Program has recognized exemplary and sustained contributions to undergraduate education at MIT. The program is named in honor of Margaret MacVicar, the first dean...
