Stem Cells Successfully Generate a Fully Functional Liver

    by Rideeta Raquib Approximately 30 million people are affected by liver disease globally, and the quest to find donors for liver transplants is difficult. There is a lack of functional livers available compared to the liver disease patient population. In some cases, a portion of the liver from a living donor is sufficient for regular function. Stem cells are unspecialized cells that can differentiate … Continue reading Stem Cells Successfully Generate a Fully Functional Liver

Visualizing Microbial Evolution on Antibiotic Landscape

By Jalwa Afroz Bacteria survive by evolving and reproducing in order to overcome environmental challenges. However, there is very little information available on how bacteria physically move in order to attain an environment that is suitable for their needs. Scientists from Harvard Medical School and Technion-Israel Institute of Technology have designed a simple way to show how bacteria move as they become resistant to drugs. … Continue reading Visualizing Microbial Evolution on Antibiotic Landscape

‘Super-agers’ Retain Youthful Memories

  By Jalwa Alfroz As humans age, it is normal for cognitive skills, such as memory, to decline. However, some people seem to escape this fate, and are subsequently categorized as super-agers. Investigators at the Harvard-affiliated Massachusetts General Hospital, led by Dr. Bradford Dickerson, revealed that certain areas of the brains of older adults with extraordinary memory performance looked similar to those of young adults. Previously, … Continue reading ‘Super-agers’ Retain Youthful Memories

Potential Means of Controlling Fevers

by Richard Liang   The human body is equipped with effective mechanisms that maintain thermal homeostasis. For example, fevers can be induced to provide an optimal environment to fight certain diseases. However, it is vital that fever temperatures are maintained within a particular threshold. They cannot be too low or the energy available for enzyme activity will be too low. They cannot be too high … Continue reading Potential Means of Controlling Fevers

New Enzyme Responsible for Cell Mediated Death Identified

by Richard Liang   The human body has developed mechanisms to deal with genetically damaged cells before they can become a threat. One such mechanism occurs when DNA is excessively damaged. Cells undergo cell death mediated by an enzyme known as poly ADP-ribose polymerase-1 (PARP-1). However, in certain instances like a stroke, the PARP-1 pathway is overly activated, causing mass cell death in the body. … Continue reading New Enzyme Responsible for Cell Mediated Death Identified

Effects of Second Hand Marijuana Smoke

by Richard Liang   Though it is known that second hand smoke from tobacco is extremely detrimental to one’s health, second hand marijuana smoke is often seen as less harmful. However, a recent study led by Dr. Xiaoyin Wang and his team of researchers from the Cardiology Division of The University of California supports the theory that second hand marijuana smoke might not be so harmless … Continue reading Effects of Second Hand Marijuana Smoke

The Relationship between Asplenia and Invasive Pneumococcal Disease

by Caleb Sooknanan   Pneumococcal disease is a bacterial infection caused by Streptococcus pneumoniae that occurs mainly among infants and young children. Invasive pneumococcal disease (IPD) is a more serious form of the infection that can cause meningitis, or bacterial infection in the blood, inflammation of the lungs, and other conditions. Bacterial infection, also known as sepsis, is especially common among patients who have undergone spleen … Continue reading The Relationship between Asplenia and Invasive Pneumococcal Disease

New Study on UTI Antibiotic Resistance

by Caleb Sooknanan   Urinary tract infections, also known as UTIs, are a prevalent series of pediatric infections that damage the urinary system. Febrile, or fever-inducing, urinary tract infections are occurring more frequently among patients. Antibiotics have become widespread assets for treating the disease, but they are not effective in all cases. Dong Sup Lee and his team of researchers at the Catholic University of Korea … Continue reading New Study on UTI Antibiotic Resistance

Infectious Disease Information and Emotional Responses

by Megan Tan   Infectious disease outbreaks cause individuals to react differently in response to this kind of emotional news. Professor Scott Clifford and Professor Jennifer Jerit, from the Department of Political Science at the University of Houston and Loyola University respectively, research two of these reactions to infectious disease outbreaks: disgust and anxiety. In the first study, a questionnaire was distributed to three sample … Continue reading Infectious Disease Information and Emotional Responses

Learning Quantifiers Across Different Languages

by Megan Tan   Researchers understand what it takes to learn a new language, but the acquisition of numerical words is unknown. In order to test this problem, Professor Napolean Katsos, from the Department of Theoretical and Applied Linguistics at University of Cambridge, and her team of researchers conducted an experiment on a group of children who spoke one of 31 languages. There were 768 children … Continue reading Learning Quantifiers Across Different Languages

The Rich Are Getting Richer

by Megan Tan   Wealth inequality is a disturbing concern in today’s economy, since a small percent of the population owns so much of the wealth. Several explanations and solutions have been proposed to see if there is a way to evenly distribute the wealth. However, all of these have faults that do not fully solve the problem at hand. Professor Yonatan Berman, from The … Continue reading The Rich Are Getting Richer
