Engineers Translate Brain Signals directly into Speech

Advance marks critical step toward brain-computer interfaces that hold immense promise for those with limited or no ability to speak. In a scientific first, Columbia neuroengineers have created a system that translates thought into intelligible, recognizable speech. By monitoring someone’s brain activity, the technology can reconstruct the words a person hears with unprecedented clarity. This breakthrough, which harnesses the power of speech synthesizers and artificial intelligence, could lead to new ways for computers to communicate directly with the brain...

Cancer: A Mutation that Breaks Gene Interplay in 3D

Scientists have discovered how a mutated gene can affect the three-dimensional interactions of genes in the cell, leading to various forms of cancer. Inside the cell, DNA is tightly wrapped around proteins and packed in a complex, 3D structure that we call “chromatin.” Chromatin not only protects our genetic material from damage, but also organizes the entire genome by regulating the expression of genes in three dimensions, unwinding them to be presented to the cell’s gene-expression machinery and then winding them back in.

Inside the 3D chromatin structure there are certain regions called “topologically associating domains” or TADs...

Steriods: Causes of Cortisone-induced Side effects

Patients undergoing long-term treatment with steroids may suffer from metabolic side effects. Researchers at the Helmholtz Zentrum München and the Ludwig Maximilians University of Munich (LMU), partners in the German Center for Diabetes Research (DZD), have now pinpointed a mechanism that leads to so-called steroid diabetes. Their findings have been published in Nature Communications.

“Glucocorticoids such as cortisone have been used to treat inflammatory diseases such as asthma or rheumatism for many decades, and they are the most commonly prescribed anti-inflammatory drugs,” explains Prof...
