‘Peanut Butter’ Test Helps Diagnose Alzheimer’s
October 9, 2024 11:56 am Videos CommentsA dollop of peanut butter and a ruler to test for smell sensitivity can be used to confirm a diagnosis of early stage Alzheimer’s disease, researchers have found.
Researchers Sharpen DNA Mapping
October 8, 2024 11:12 am Videos CommentsWith high-tech optical tools and sophisticated mathematics, researchers have found a way to pinpoint the location of specific sequences along single strands of DNA, a technique that could someday help diagnose genetic diseases.
Laser Provides Better Diabetes, Retinal Disease Treatments
September 25, 2024 1:19 pm Videos CommentsA new laser, the Supra Scan Multi-spot Laser, is helping experts provide better treatment for eye diseases. This advanced laser can prevent blindness for some patients with serious conditions. The first patient received treatment from the laser for proliferative diabetic retinopathy on July 22.
Study Brings Universal Flu Vaccine a Step Closer
September 23, 2024 11:29 am Videos CommentsScientists have moved closer to developing a universal flu vaccine by using the 2009 swine flu pandemic to study why some people seem to resist severe illness. Researchers asked volunteers to donate blood samples just as the pandemic was getting underway and also asked the volunteers to report any symptoms they experienced over the next two flu seasons.
Tumors Caught Bursting Through a Blood Vessel
September 20, 2024 12:05 pm Videos CommentsResearchers at MIT have developed a microfluidic device that mimics the process of extravasation, showing the flow of cancer cells through a system of blood vessels. The extravasation process is a crucial step in cancer metastasis that, until now, has been unclear.
Bioscience Technology Update for September 20, 2024
September 20, 2024 11:46 am Videos CommentsIn this edition of Bioscience Technology Update: Surgeons Successfully Implant Bioengineered Vein Genetically Modified Mosquitoes Lose Appetite for Humans Bacteria Ingested Through Yogurt Affects Brain Function Young Genes Can Become Essential for Life
Healthy Lifestyle Can Lengthen Telomeres, Slow Aging
September 17, 2024 10:44 am Videos CommentsA small pilot study shows for the first time that changes in diet, exercise, stress management and social support may result in longer telomeres, the parts of chromosomes that affect aging. It is the first controlled trial to show that any intervention might lengthen telomeres over time.
Functioning Gears Found in Nature for the First Time
September 13, 2024 11:17 am Videos CommentsPreviously believed to be only man-made, a natural example of a functioning gear mechanism has been discovered in a common insect- showing that evolution developed interlocking cogs long before we did. The juvenile Issus has hind-leg joints with curved cog-like strips of opposing “teeth” that intermesh, rotating like mechanical gears to synchronize the animal’s legs when it launches into a jump.
Embryonic Stem Cells Created in Adult Organism
September 12, 2024 11:49 am Videos CommentsA research team has become the first to make adult cells from a living organism retreat in their evolutionary development to recover the characteristics of embryonic stem cells. They have also discovered that these embryonic stem cells have a broader capacity for differentiation than those obtained via in vitro culture.
U.S. Faces Crisis in Cancer Care
September 11, 2024 1:09 pm Videos CommentsDelivery of cancer care in the U.S. is facing a crisis stemming from a combination of factors—a growing demand for such care, a shrinking oncology work force, rising costs of cancer care, and the complexity of the disease and its treatment, says a new report from the Institute of Medicine.
Inner-ear Disorders May Cause Hyperactivity
September 6, 2024 10:08 am Videos CommentsBehavioral abnormalities are traditionally thought to originate in the brain. But a new study has found that inner-ear dysfunction can directly cause neurological changes that increase hyperactivity. The study, conducted in mice, also implicated two brain proteins in this process, providing potential targets for intervention.
Stress-related Protein Speeds Alzheimer’s Progression
September 4, 2024 11:40 am Videos CommentsA stress-related protein genetically linked to depression, anxiety and other psychiatric disorders contributes to the acceleration of Alzheimer’s disease, a new study has found. When the protein FKBP51 partners with another protein, Hsp90, the team prevents the brain from clearing the toxic tau protein, associated with Alzheimer’s disease.
TB Has Surprising Family Tree
September 3, 2024 11:42 am Videos CommentsFor years, physicians around the world have watched as strain after strain of the deadly bacteria mycobacterium tuberculosis evolves resistance to drugs. A new method of analyzing whole genome sequences of TB, applied to a massive set of strains of the bacteria collected from clinics around the world, has revealed 39 new genes associated with elevated drug resistance.
Researchers Discover a Potential Cause of Autism
August 29, 2024 10:27 am Videos CommentsProblems with a key group of enzymes called topoisomerases can have profound effects on the genetic machinery behind brain development and potentially lead to autism spectrum disorder (ASD). Scientists at the University of North Carolina School of Medicine have described a finding that represents a significant advance in the hunt for environmental factors behind autism and lends new insights into the disorder’s genetic causes.
Researcher Controls Colleague’s Motions in First Human Brain-to-brain Interface
August 27, 2024 3:36 pm Videos CommentsResearchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher, using electrical brain recordings and a form of magnetic stimulation.
