An accidental laboratory observation during an ongoing cancer research project on mice led acclaimed Greek geneticist Dr. Constantine Stratakis to a breakthrough discovery on weight management, which could help people battle obesity more easily in the future.
The discovery, which made international headlines following its publication, sheds light on key brain mechanisms related to healthy lifestyle behaviors.
In an exclusive interview with
Greek Reporter, the head of the Department of Genetics and Endocrinology at the National Institute of Child Health and Human Development (NICHD) in Washington, D.C., stresses that scientists should always keep an open mind for accidental findings like this.

KANSAS CITY, MO Researchers at the Stowers Institute for Medical Research, in collaboration with colleagues at Stanford University and Technical University of Munich have developed advanced explainable artificial intelligence (AI) in a technical tour de force to decipher regulatory instructions encoded in DNA. In a report published online February 18, 2021, in
Nature Genetics, the team found that a neural network trained on high-resolution maps of protein-DNA interactions can uncover subtle DNA sequence patterns throughout the genome and provide a deeper understanding of how these sequences are organized to regulate genes.
New surgery may enable better control of prosthetic limbs
February 16, 2021MIT
MIT researchers have invented a new type of amputation surgery that can help amputees to better control their residual muscles and sense where their “phantom limb” is in space. This restored sense of proprioception should translate to better control of prosthetic limbs, as well as a reduction of limb pain, the researchers say.
In most amputations, muscle pairs that control the affected joints, such as elbows or ankles, are severed. However, the MIT team has found that reconnecting these muscle pairs, allowing them to retain their normal push-pull relationship, offers people much better sensory feedback.
