A team of scientists, including researchers from MIT, have found that Martian rocks uncovered by NASA’s Perseverance contain “signs of a watery past and are loaded with the kind of organic molecules that are the foundations for life as we know it,” reports Joel Achenbach for The Washington Post. “On balance, we are actually super lucky that there are igneous rocks in the crater, and that we happened to land right on them, since they are ideal for determining ages and studying the past history of Mars’ magnetic field,” says Prof. Benjamin Weiss.

NASA’s Perseverance rover has uncovered evidence of habitable conditions that once existed on Mars, reports Becky Ferreira for Vice. “In that kind of environment, we’re seeing very, very strange chemistry which is not common on Earth at all, but seems to be more common on Mars because we’ve seen these kinds of materials in almost all the missions now,” says postdoctoral fellow Eva Scheller.

Fortune reporter Gabby Shacknai spotlights Joy Buolamwini PhD ’22 and her research in racial bias in AI. “After finishing grad school, Biolamwini decided to continue her research on A.I.’s racial bias and quickly realized that much of this was a result of the non-diverse datasets and imagery used by a disproportionately white, male tech workforce to train A.I. and inform its algorithms,” writes Shacknai.

MIT researchers have found that standard autism diagnostic tests could be “stymieing discovery of sex differences in autism,” reports Ingrid Wickelgren for Scientific American. “To qualify for the study, prospective participants had to take a standard activity-based assessment for autism to confirm their diagnosis,” says Wickelgren. “After testing, half of the 50 girls and women who would otherwise be eligible for the scientists’ study did not meet the test’s criteria for autism.”

MIT scientists have developed a miniature antenna that could one day be used to help safely transmit data from within living cells “by resonating with acoustic rather than electromagnetic waves,” reports Andrew Chapman for Scientific American. “A functioning antenna could help scientists power, and communicate with, tiny roving sensors within the cell,” writes Chapman, “helping them better understand these building blocks and perhaps leading to new medical treatments.”

Popular Science reporter Andrew Paul writes that a study co-authored by Institute Prof. Daron Acemoglu examines the impact of automation on the workforce over the past four decades and finds that “‘so-so automation’ exacerbates wage gaps between white and blue collar workers more than almost any other factor.”

A new study by MIT scientists finds that Earth can self-regulate its temperature thanks to a stabilizing feedback mechanism that works over hundreds of thousands of years, reports Troy Farah for Salon. “The finding has big implications for our understanding of the past, but also how global heating is shaping the future of our home world,” writes Farah. “It even helps us better understand the evolution of planetary temperatures that can make the search for alien-inhabited exoplanets more fruitful.”

SeedLabs is working with a team including the MIT Media Lab Space Exploration Initiative to test out “microbes’ capabilities in space, potentially providing important advancements for both pollution reduction on earth as well as uses for astronauts during future lunar and Maritain explorations,” reports Andrew Paul for Popular Science.

The MIT Media Lab Space Exploration Initiative is working with SeedLabs, the environmental division of Seed Health, to study how microbes perform in space. “Along with testing how the microbes perform in a zero-gravity, high UV radiation-environment, the experiment could also be the starting point to exploring a future in which astronauts have a system to recycle their plastic waste and turn it into new materials,” reports Kristin Toussaint for Fast Company.  

A study co-authored by researchers from MIT found that a person’s ancestry can impact CRISPR’s ability to edit genomes as intended, “particularly in people of African descent, whose genomes are most likely to differ from those used to steer CRISPR to a specific gene,” reports Jocelyn Kaiser for Science.

Researchers at MIT have found indoor humidity levels can influence the transmission of Covid-19, reports Dennis Thompson for US News & World Report. “We found that even when considering countries with very strong versus very weak Covid-19 mitigation policies, or wildly different outdoor conditions, indoor — rather than outdoor — relative humidity maintains an underlying strong and robust link with Covid-19 outcomes,” explains Prof. Lydia Bourouiba.

MIT researchers have found that relative humidity “may be an important metric in influencing the transmission of Covid-19,” reports Sophie Mellor for Fortune, “Maintaining an indoor relative humidity between 40% and 60% – a Goldilocks climate, not too humid, not too dry – is associated with relatively lower rates of Covid-19 infections and deaths,” writes Mellor.

Boston Globe correspondent Scott Kirsner explores the growth of quantum computing from the field's roots “at a 1981 meeting in Dedham, at MIT’s Endicott House conference center.” Bharath Kannan PhD ’22, co-founder and CEO of Atlantic Quantum, notes that if researchers could develop a computer that was natively quantum mechanical, "it would be game-changing for a lot of industries.”

Nature reporter Elie Dolgin writes that a new study by MIT researchers explores the role of the gene variant APOE4 in Alzheimer’s, and finds that the gene is linked with faulty cholesterol processing in the brain, impacting the insulation around nerve cells and potentially causing memory and learning deficits. “The work suggests that drugs that restore the brain’s cholesterol processing could treat the disease,” writes Dolgin. 

Prof. Kevin Esvelt speaks with New Scientist reporter Michael Le Page about his work outlining a roadmap to help counter the risk posed by pandemic terrorism. “The message is, this is serious but this is totally solvable,” says Esvelt.
