New work shows that histones, long treated as boring spools for DNA, sit at the center of the origin story of eukaryotes and continue to play important roles in evolution and disease.

—THE STUDY ESTABLISHES A NOVEL CONCEPT OF “TUMOR SUPPRESSIVE DRUG RESISTANCE”
—THE COMBINATION OF LB-100 WITH INHIBITORS OF CELLULAR STRESS RESPONSE MODULATORS WAS HIGHLY EFFECTIVE IN KILLING CANCER CELLS IN SEVERAL PRE-CLINICAL CANCER MODELS
—RESISTANCE TO THIS THERAPY CAN RESULT IN THE LOSS OF THE ONCOGENIC PROPERTIES OF CANCER CELLS
People can lower their risks of getting many common kinds of cancer by making healthy choices. Screening tests can find some cancers early when treatment works best. Vaccines (shots) can help prevent several kinds of cancer. Learn more about how to lower your risk of getting cancer.

Targeting calcium signaling in neurons represents a promising therapeutic approach for treating a rare form of schizophrenia, according to a Northwestern Medicine study published in Biological Psychiatry.
“This is the first time that human neurons are made and characterized from schizophrenia patients with the 16p11.2 duplication, one of the most prominent genetic risk factors in schizophrenia, and the first time that calcium signaling is found as a central abnormality in schizophrenia neurons,” said Peter Penzes, Ph.D., the Ruth and Evelyn Dunbar Professor of Psychiatry and Behavioral Sciences and senior author of the study.
Schizophrenia is characterized by auditory and visual hallucinations, delusions, and trouble with forming and sorting thoughts, which severely impacts productivity and overall quality of life. The disease, which affects roughly one percent of the general population, has strong genetic associations, however the exact genes involved are unknown.
This is a talk given to the Department of Biotechnology at Indian Institute of Technology Madras in January 2023.
A 3D mesh is a three-dimensional object representation made of different vertices and polygons. These representations can be very useful for numerous technological applications, including computer vision, virtual reality (VR) and augmented reality (AR) systems.
Researchers at Florida State University and Rutgers University have recently developed Wi-Mesh, a system that can create reliable 3D human meshes, representations of humans that can then be used by different computational models and applications. Their system was presented at the Twentieth ACM Conference on Embedded Networked Sensor Systems (ACM SenSys ‘22), a conference focusing on computer science research.
“Our research group specializes in cutting-edge wi-fi sensing research,” Professor Jie Yang at Florida State University, one of the researchers who carried out the study, told Tech Xplore. “In previous work, we have developed systems that use wi-fi devices to sense a range of human activities and objects, including large-scale human body movements, small-scale finger movements, sleep monitoring, and daily objects. Our E-eyes and WiFinger systems were among the first to use wi-fi sensing to classify various types of daily activities and finger gestures, with a focus on predefined activities using a trained model.”
A Quebec hospital adopts a novel use of VR to help patients with anxiety, phobias and pain.
In a newswire release today, the Fondation de l’Hôtel-Dieu d’Alma (the Alma Hospital Foundation) announced the launch of a virtual reality (VR) project aimed at improving the mental health of those experiencing increasing anxiety. The Alma Hospital is a regional health centre for the area of Lac St. Jean and the Saguenay River valley to the north of Quebec City.
Jean Lamoureux, the hospital’s Executive Director states, “The number of requests for mental-health consultations is estimated to have increased by 30 to 40 percent during the pandemic. These needs are urgent…and, thanks to the innovation of Paperplane Therapeutics and TELUS, we will transform the way health services are delivered, while having a significant positive impact on patient well-being through technology.”
