Victor Ambros ‘75, PhD ‘79 and Gary Ruvkun have won the 2024 Nobel Prize in Physiology or Medicine for “their groundbreaking work on how genes behave,” reports Patrick Smith for NBC News. Ambros and Ruvkun, who worked as postdocs in the lab of Professor H. Robert Horvitz in the late 1980s, discovered how microRNA molecules play a key role in gene regulation. "The pair sought to explore how nerve cells and muscle cells, for example, have very different characteristics despite having the same genetic information," writes Smith.

A new study by MIT scientists proposes that researchers should be able to detect near-flying primordial black holes by measuring the orbit of Mars, reports Darren Orf for Popular Mechanics. The researchers found that “if a primordial black hole passed within a few hundred million miles of the Red Planet, then a few years later, the planet’s orbit would have shifted by the small (but technically detectable) distance of about a meter,” Orf explains.

Prof. Kerry Emanuel speaks with Washington Post reporters Sarah Kaplan, Shannon Osaka and Dan Stillman about the future of hurricane forecasting. “This is one thing that scares me, if these things can intensify more rapidly,” says Emanuel. “We’re going to have cases where forecasters go to bed with a tropical storm and wake up with a Category 5 when it’s too late to evacuate people.”

A new study by MIT researchers suggests that “Mars’ missing atmosphere may be locked up in the planet’s clay-rich surface,” reports Tom Howarth for Newsweek. “According to the researchers, ancient water trickling through Mars' rocks could have triggered a series of chemical reactions, converting CO2 into methane and trapping the carbon in clay minerals for billions of years,” explains Howarth.

MIT physicists have discovered that "black holes the size of an atom that contain the mass of an asteroid may fly through the inner solar system about once a decade” and could cause planets or large moons slightly off course, reports Clara Moskowitz for Scientific American  “As it passes by, the planet starts to wobble,” says Sarah R. Geller '12, SM '17, PhD '23. “The wobble will grow over a few years but eventually it will damp out and go back to zero.”

Postdoctoral research Wenxuan Jia PhD '24 and colleagues at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have developed a way to reduce the impact of quantum noise by squeezing the laser light used in the detectors, enabling scientists to double the number of gravitational waves they can find, reports Karmela Padavic-Callaghan for New Scientist. “We realized that quantum noise will be limiting us a long time ago,” says Jia. “It’s not just a fancy [quantum] thing to demonstrate, it’s something that really affects the actual detector.” 

Research Scientist Josh Bendavid PhD '13 and his colleagues have “produced a new value for the W boson mass,” a "fundamental particle that is crucial for processes like nuclear decay and setting the mass of the Higgs boson,” reports Alex Wilkins for New Scientist. The result is in line with predictions made in the standard model of particle physics. “The standard model survives for the moment,” said Bendavid of the findings. 

A study by researchers at MIT and elsewhere has found that both lawyers and non-lawyers use legalese when asked to write about laws, reports June Casagrande for The Los Angeles Times. The "researchers tested the hypothesis by asking 200 participants to write laws prohibiting crimes like drunk driving and burglary,” explains Casagrande. “Then they asked them to write stories about those crimes. The laws they wrote contained unnecessarily long, labyrinthine sentences with lots of parenthetical explanations crammed in. The stories, however, were written simply, without the parenthetical information stuffing.” 

MIT physicists have found that “the presence of a tiny black hole speeding through the solar system could be identified by the gentle gravitational nudge it exerted on the Earth and other planets, which would alter their orbital paths by no more than a few feet,” reports Noah Haggerty for The Los Angeles Times. “It’s just fantastic that the most conceptually conservative response is to say, ‘It’s just super tiny black holes that were made a split second after the Big Bang,’” says Prof. David Kaiser. “It’s not inventing new forms of matter that have not yet been detected. It’s not changing the laws of gravity.”

A new study by MIT researchers suggests that miniscule black holes could briefly wobble the orbit of Mars and that these tiny black holes may pass through our solar system once every decade or so, reports Jess Thomson for Newsweek. “The researchers modeled the orbits of every large body in the solar system,” writes Thomson, “and found that tiny wobbles in the orbit of Mars could indicate one of the asteroid-mass black holes passing through.”

Science News reporter Emily Conover spotlights a new study by MIT researchers that proposes a new method to search for microscopic primordial black holes, which, if they exist, “could explain some or all of the universe’s dark matter.” The researchers suggest that when a primordial black hole passes close to a planet, it could “produce noticeable effects despite its tiny size.”
 

MIT scientists have “observed and captured images of a rare ‘edge state’ in ultracold atoms,” reports Rupendra Brahambhatt for Interesting Engineering. “Using these findings, they can learn to achieve and harness the edge states of electrons in different materials,” notes Brahambhatt. “This breakthrough in the field of quantum physics could lead to the discovery of practically infinite energy sources.”

Los Angeles Times reporter Rosanna Xia spotlights Prof. Susan Solomon’s new book, “Solvable: How We Healed the Earth, and How We Can Do It Again,” as a hopeful remedy to climate anxiety. “An atmospheric chemist at MIT whose research was key to healing the giant gaping hole in our ozone layer, Solomon gives us much-needed inspiration — and some tangible ways forward,” explains Xia. 

Prof. Nancy Kanwisher has been named a recipient of the 2024 Champalimaud Foundation’s Vision Award, reports the Associated Press. The award highlights the collective work of four researchers who have “driven significant progress in the field of visual neuroscience." 

The Boston Globe’s Angelina Parrillo interviews Jasmina Aganovic ’09 about her beauty company Arcaea, which reconstructs data from extinct flowers to produce fragrances. “I viewed fragrance as this remarkable emotional storytelling category and people don’t view science as being associated with creativity, emotion, or storytelling,” Aganovic says. “I think that that’s very far from the truth.”
