Megan Brickley is an anthropology professor at McMaster University and holds the Canada Research Chair in the Bioarchaeology of Disease. She has been engaged in a series of research papers — together with PhD candidate Lori D-Ortenzio — looking at ways that the body records serious deficiencies of Vitamin D — also known as rickets. … Continue reading The Big Question with Megan Brickley
To make sense of human voices, we rely on senses beyond hearing. The songs of Taylor Swift can be sweet and soft. Lady Gaga’s singing feels dark. Johnny Cash’s voice was low and rough. That’s because voice is not just sound: it can be seen and heard, but also tasted and touched. The sound we … Continue reading Rough, smooth or deep: why the sound of a voice is multisensory
Bone measurement analysis indicates that the remains found on a remote island in the South Pacific were likely those of legendary American pilot Amelia Earhart, according to a UT researcher. Richard Jantz, professor emeritus of anthropology and director emeritus of UT's Forensic Anthropology Center, re-examined seven bone measurements conducted in 1940 by physician D. W. … Continue reading Bone analysis confirms bones belong to Amelia Earhart
This is an excerpt from The Cosmic Machine: The Science That Runs Our Universe and the Story Behind It By Scott Bembenek, PhD Aristotle (c. 384 BC–c. 322 BC) was born in Stagira, Greece. His father was the personal physician to the King of Macedonia, a position he inherited. Aristotle studied with Plato (c. 427 BC–c. 347 … Continue reading Speculations of Atoms: Why Aristotle?
The immune cells douse the bacteria with a toxic cocktail that contains, among other things, chlorine bleach. This leads to the oxidation of proteins inside the bacterial cell within seconds, resulting in bacterial death. The researchers published their report in the journal E-Life from 6.3.2018. White blood cells devour bacteria When bacteria enter the blood … Continue reading Immune cells engage in chemical warfare to kill bacteria
Immune systems that develop only partial immunity to a bacterial pathogen drive the evolution of more potent strains of the bacteria, a new study in house finches reveals. The results demonstrate how, even though the immune system is meant to protect its host, it can sometimes inadvertently help the "enemy" become stronger (by selecting for … Continue reading Sometimes an immune system response only makes things worse
Assistant Professor Ngai-Man (Man) Cheung is a researcher with the Information Systems Technology and Design Pillar at the Singapore University of Technology and Design. His research interests are image / signal analysis, computer vision and machine learning with applications to health care. His team has invented an early skin cancer detection technology using computer vision … Continue reading The Big Question with Cheung Ngai-Man
The first decades of the 20th century saw a raft of psychological terms fall into popular usage. Freudian notions of ‘denial’ and ‘displacement’, ‘projection’ and ‘transference’, were the first to become part of everyday language; thanks to Alfred Adler, feelings of ‘inferiority’ and ‘superiority’ (and the forms of compensation that accompanied the former) were soon … Continue reading What was the beguiling spell of Jung’s ‘collective unconscious’?
Information scientists at the U.S. Army Research Laboratory and the University of Michigan have borrowed from the popular game "20 Questions," to make an important step towards helping robots maintain continuous and purposeful conversation with humans. They have developed an optimal strategy for asking a series of yes/no questions that rapidly achieves the best answer. … Continue reading This is 20 Questions, AI-style
Biochemists have made a discovery that sheds light on the molecular machinery that allows some cells, such as immune cells or even malignant cancer cells in humans, to wiggle their way through tissues like organs, skin or bones. The work, conducted in the University of Oregon laboratory of Brad Nolen, a professor in the Department … Continue reading Scientists figure out how cells take a walk
