Researchers from MIT have developed a new satellite observation technique that can help gauge the strength of ancient rivers on Mars and active liquid methane rivers on Titan, Saturn’s largest moon, reports Jamie Carter for Forbes. “What’s exciting about Titan is that it’s active, and on Mars, it gives us a time machine, to take the rivers that are dead now and get a sense of what they were like when they were actively flowing,” says Prof. Taylor Perron. “With this technique, we have a method to make real predictions for a place where we won’t get more data for a long time.”

Using a new satellite observation technique, researchers from MIT and elsewhere have determined the flow of dried-up rivers on Mars and currently active liquid methane rivers on Titan, Saturn’s largest moon. “Both kinds are of scientific interest because they could reveal the role rivers play in shaping the worlds’ environments,” reports Isaac Schultz for Gizmodo.

Lecturer Guadalupe Hayes-Mota SB '08, MS '16, MBA '16 writes for Forbes about the ethical framework needed to mitigate risks in artificial intelligence. “[A]s we continue to unlock AI's capabilities, it is crucial to address the ethical challenges that emerge,” writes Hayes-Mota. “By establishing a comprehensive ethical framework grounded in beneficence, non-maleficence, autonomy, justice and responsibility, we can ensure that AI's deployment in life sciences aligns with humanity's best interests.”

MIT researchers have found that lawyers prefer, and better understand, simplified texts, rather than legalese, reports Jesse Greenspan for Scientific American. “The researchers presented 105 U.S. attorneys with contract excerpts written in both “legalese” and plain English and tested their comprehension and recall for each,” explains Greenspan. “While the attorneys outperformed laypeople overall, they still found the legalese contracts harder to grasp than those written in plain English.”

Researchers at MIT have developed a soft robot that can be controlled by a weak magnetic field and travel through tiny spaces within the human body, reports Andrew Paul for Popular Science. “Because of their soft materials and relatively simple manipulation, researchers believe such mechanisms could be used in biomedical situations, such as inching through human blood vessels to deliver a drug at a precise location,” explains Paul.

MIT has been selected as the world’s best university in the 2024 QS World University Rankings, reports Cecilia Rodriguez for Forbes. MIT has secured “the top position for the 12^th consecutive year,” writes Rodriguez.

MIT researchers have discovered an RNA-guided DNA-cutting enzyme in eukaryotes, reports Science. “The researchers speculate that eukaryotic cells may have gained the newly identified editing genes from transposable elements—so-called jumping genes—they received from bacteria,” writes Science.

Prof. Max Tegmark speaks with Guardian reporter Steve Rose about the potential of artificial intelligence. “The positive, optimistic scenario is that we responsibly develop superintelligence in a way that allows us to control it and benefit from it,” says Tegmark. “If we can build and control superintelligence, we can quickly go from being limited by our own stupidity to being limited by the laws of physics. It could be the greatest empowerment moment in human history.”

Prof. Richard Young and his colleagues have discovered that many transcription factors can bind RNA, reports Christie Wilcox for Science. "The team decided to investigate after scattered reports suggested that at least some transcription factors are capable of binding RNA even though they lack traditional RNA binding domains,” writes Wilcox. 

MIT researchers have identified a new biological editing system that could “potentially be even more precise than CRISPR gene editing,” reports Laura Baisas for Popular Science. The new system, based on a protein called Fanzor, is “the first programmable RNA-guided system discovered in eukaryotes,” Baisas notes.

Researchers from MIT and Duke have discovered that introducing weaker bonds into a material can produce stronger polymers, reports Norbert Sparrow for Plastics Today. “Side-chain cross-linked polymers are probably the most widely used type of polymer network,” says postdoc Shu Wang. “The concept [outlined] in our paper should work for all polymer networks that are side-chain cross linked.”

MIT scientists have found that the “motions of undulating animals and the states of quantum objects can be described using strikingly similar equations,” writes Karmela Padavic-Callaghan for New Scientist. The similarity “allowed the team to use mathematical tools previously developed by quantum physicists to analyze the animals,” notes Padavic-Callaghan. “For instance, the team quantified how differently a snake-like robot and a C. elegans move and created a diagram that placed them on a spectrum of other undulating creatures.”

New York Times reporter Natasha Singer spotlights the Day of AI, an MIT RAISE program aimed at teaching K-12 students about AI. “Because AI is such a powerful new technology, in order for it to work well in society, it really needs some rules,” said MIT President Sally Kornbluth. Prof. Cynthia Breazeal, MIT’s dean of digital learning, added: “We want students to be informed, responsible users and informed, responsible designers of these technologies.”

Astrophysicist Frank Shu '63, who is credited with making pivotal contributions to our understanding of galaxies and star formation, has died at the age of 79, reports Douglas Lin and Fred Adams for Nature. “For the past dozen years, his concern about the climate crisis led him to study the use of molten-salt reactors to generate energy from nuclear waste and to convert waste biomass into inert products that can be sequestered, removing carbon from the atmosphere,” write Lin and Adams.

Researchers at MIT have found that lawyers “have an easier time remembering legal documents written in simple English over those filled with so-called legalese,” reports Ed Cara for Gizmodo. “On average, for instance, lawyers scored 45% on a test that asked them to recall documents written in legalese, compared to the average 38% scored by nonlawyers,” explains Cara. “But the lawyers’ score also increased to over 50% when they were given the simplified version.”
