Philip Ball of The Guardian speaks with graduate student Steve Ramirez about the potential for neuroscientist to one day be able to replace bad memories with good ones. “I see a world where we can reactivate any kind of memory we like, or erase unwanted memories,” says Ramirez.
Researchers from MIT have detected the brightest pulsar ever recorded, reports Brook Hays of UPI. “Despite its small dimensions and modest mass, the pulsating dead star is burning with the energy of 10 million suns,” writes Hays.
Carolyn Johnson of The Boston Globe reports on a new paper by MIT Prof. Pawan Sinha and others that says an inability to make good predictions may explain autism. “Researchers suggest people with autism spectrum disorder may perform repetitive behaviors because personal habits and rituals are a safe harbor in a world they find alarmingly out of control,” writes Johnson.
The Economist reports on an MIT study on the effectiveness of massive open online courses or MOOCs. Researchers found that MOOC participants “learned slightly more than they typically would in lectures.”
Niina Heikkinen reports for Scientific American that MIT researchers have identified a new way to make yeast more ethanol-tolerant. The researchers were able to improve “alcohol tolerance and extend the amount of time that individual cells could produce ethanol.”
Macrina Cooper-White of The Huffington Post writes that MIT researchers have found evidence that the giant basin on the moon was created by ancient volcanic eruptions and not from an asteroid impact. An asteroid would have created a circular basin, but researchers found that the basin is actually more rectangular in shape, Cooper-White reports.
Jonathan Amos of BBC News reports that MIT researchers have identified a large rectangular feature on the moon. “The 2,500km-wide structure is believed to be the remains of old rift valleys that later became filled with lava,” writes Amos.
Washington Post reporter Rachel Feltman writes that researchers have found evidence that the moon’s basin was formed by magma flows. "For anyone who's ever looked up at the moon and wondered why it has this pattern on its surface — now we have an answer,” says MIT Vice President for Research Maria Zuber.
Thomas Burton of The Wall Street Journal writes that MIT researchers were among those awarded the first research grants under President Obama’s new BRAIN Initiative. Burton writes that one of the MIT grants will go toward “determining which exact brain circuits are involved in generating short-term memories that influence decisions.”
Boston Globe reporter Deborah Kotz writes that MIT researchers have been awarded new grants from the National Institutes of Health to further brain research. “Biophysicist Alan Jasanoff received a grant to develop imaging agents for functional MRI imaging that would target the flow of calcium into and out of brain cells,” writes Kotz of one of the MIT grants.
MIT neuroscientists were among the recipients of new grants for brain research from the National Institutes of Health, reports Jon Hamilton for NPR. Hamilton explains that as part of one grant, “Researchers from the Massachusetts Institute of Technology will try to adapt functional MRI so that it can show the activity of individual brain cells.”
Professor Max Tegmark weighs in on the importance of Hugh Everett’s theory of the multiverse and his work developing the concept of mutually-assured destruction in a New Scientist article by Rowan Hooper. Everett “wrote arguably the first ever serious report on just how devastating a nuclear war would be for the US," says Tegmark.
Raghu Dhara of The Harvard Crimson writes that a new study by researchers from MIT, Harvard and Tsinghua University found that online courses are just as effective as traditional university courses. The study found that “the ‘learning gain’ of a group of MOOC students was comparable to that achieved by students enrolled in the same course at MIT,” explains Dhara.
Issie Lapowsky writes for Wired about an MIT study that demonstrated that students who completed a physics class online learned as effectively as those who took it in person. “What’s more, the results were the same, regardless of how well the online students scored on a pre-test before taking the class,” Lapowsky writes.
In a piece for Scientific American, Amy Robinson, creative director of EyeWire, writes about multiphoton microscopy, which is used to study how the human brain adapts and grows new synapses. Robinson’s piece is part of a series about emerging neurotechnologies at MIT.
