Washington Post reporter Rachel Feltman writes that MIT researchers have used optogenetics to reactive lost memories. The research indicates that, “retrograde amnesia -- where memories are lost after brain trauma -- may be more of a memory retrieval problem than an actual loss of data.”
According to AFP, MIT researchers were able to use a technology called optogenetics to retrieve lost memories. Professor Susumu Tonegawa explains that the research showed, “past memories may not be erased, but could simply be lost and inaccessible for recall."
Graduate student Dheeraj Roy speaks with Rachel Paiste of WBUR about a new study that indicates that memories lost to amnesia may be recalled by activating brain cells with light. Roy explains that the findings show that “in certain models of amnesia, memories do persist.”
Jonathan Amos reports for The BBC on new advanced laser interferometer gravitational observatory (LIGO) facilities that are part of a project headed by MIT and Caltech to detect gravitational waves resulting from extreme cosmic events: “Confirmation of the waves' existence should open up a new paradigm in astronomy,” writes Amos.
“MIT scientists have cracked the science behind the dress that went viral on the Internet after some saw it as black and blue while others perceived it to be gold and white,” The Huffington Post reports. The researchers found that a person’s visual perception was influenced by light sources.
Guardian reporter Ian Sample writes about research by Bevil Conway, a principal research scientist at MIT, examining why people had different opinions about the color of a dress. Conway found that “our brains devise strategies for working out the true colours of objects in different situations. But because we have different experiences, our brain models differ too.”
Alison Gopnik of The Wall Street Journal writes that new research by Professor John Gabrieli indicates that poverty can have a negative impact on brain development in children. The researchers found that “low-income children had developed thinner cortices than the high-income children.”
Kathleen McKenna of The Boston Globe writes that Professor Alexander Rich, whose research confirmed DNA’s double-helix structure, died at 90 on April 27. Shuguang Zhang, associate director of the Center for Biomedical Engineering at MIT, said that Rich was “warm, wonderful, and open-minded.”
Washington Post reporter Martin Weil writes that Prof. Alexander Rich, who was known for his work with molecular biology, passed away on April 27. Rich’s work on hybridization, the pairing of two single strands of DNA or RNA, “is regarded as integral to creating much of modern biotechnology, with applications in diagnostics, forensics, genealogy and gene sequencing.”
Prof. Alexander Rich, a noted biophysicist known for his work investigating the structure of DNA and RNA, died on April 27, writes Denise Gellene for The New York Times. “I can think of no one else who has made as many major contributions to all facets of modern molecular biology,” said University of Maryland Prof. Robert C. Gallo.
Ami Albernaz reports for The Boston Globe on a new study co-authored by Prof. John Gabrieli that finds that income disparity affects brain development in children. “The findings add a biological perspective on what it means to come from a lower socioeconomic background,” says Gabrieli.
Mark Anderson profiles Institute Professor Mildred Dresselhaus, recipient of the 2015 IEEE Medal of Honor, for IEEE Spectrum, chronicling her journey from a childhood passion for music to her pioneering research on carbon. Anderson writes that Dresselhaus has “blazed a path for researchers eager to exploit the magic of carbon computing.”
MIT researchers have developed a new detector that can identify individual neutrons, reports Brid-Aine Parnell for Forbes. “While being able to spot an electron with such a small detector is major step forward in itself, it also takes the team further down the road of being able to measure the mass of a neutrino,” Parnell writes.
UPI reporter Brooks Hays writes that a team of MIT researchers has developed a tabletop device that can detect electrons and could potentially be used discover the mass of neutrinos. “Researchers recently used the device to observe the behavior of more than 100,000 electrons from decaying krypton gas,” Hays writes.
To help give her students a better understanding of the brain, Prof. Nancy Kanwisher shaved her head and had a student draw the different regions of the brain on her head, reports Melissa Malamut for Boston Magazine. Kanwisher explains that she saw her technique as a way to “discover basic components of the human mind.”
