Staying in education for longer may help maintaining a healthy heart

There are many good ways of maintaining health of your heart. You should exercise, avoid prolonged periods of sitting, eat less fat food and so on. But did you know that staying in education for longer may help you avoiding heart disease? A new study from UCL has shown that […]

Move over Gucci; researchers create designer stem cells

UW Medicine researchers recently lead a successful effort to create “designer” stem cells that might lead to advances in cancer and aging, they say. In a paper published this week in the journal PNAS, the scientists showed for the first time that a computer-generated protein can be inserted into stem cells to change their epigenetic memory, whose role is to […]

A blood test can predict early lung cancer prognosis

Cancer cells obtained from a blood test may be able to predict how early-stage lung cancer patients will fare, a team from the University of Michigan has shown. This information could be used to determine which patients are most likely to benefit from additional therapies to head off the spread […]

Nucleolus is a life expectancy predictor

Can a cell show its biological age? And is it possible to foresee an animal’s lifespan? Scientists from the Max Planck Institute for Biology of Ageing in Cologne discovered a connection between the size of the nucleolus – a tiny structure in the very center of the cell – and […]

Bone Marrow Protein May Be Target for Improving Stem Cell Transplants

Bone marrow contains hematopoetic stem cells, the precursors to every blood cell type. These cells spring into action following bone marrow transplants, bone marrow injury and during systemic infection, creating new blood cells, including immune cells, in a process known as hematopoiesis. A new study led by University of Pennsylvania […]

Ancient Chinese medicine holds the answer of an effective osteoporosis treatment

Osteoporosis is a disease which reduces bone density, increasing the risk of breaking. Osteoporosis sufferers are typically older people – it is the main reason of a broken bone among the elderly. Now scientists from The University of British Columbia have found a potential candidate for a new treatment – […]

It’s Not a Rat’s Race for Human Stem Cells Grafted to Repair Spinal Cord Injuries

More than one-and-a-half years after implantation, researchers at University of California San Diego School of Medicine and the San Diego Veterans Administration Medical Center report that human neural stem cells (NSCs) grafted into spinal cord injuries in laboratory rats displayed continued growth and maturity, with functional recovery beginning one year […]

Pluripotent Stem Cells Generated using a 3D Printer

A group of researchers from the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong had developed a way of “printing” human induced pluripotent stem cells (iPSCs) using a custom bioink. The tem behind a paper documenting the new technique, published in the journal Advanced Healthcare […]

Why placebo effect works only for some people? Scientists think they may have the answer

Everyone knows that placebo is capable of effectively reducing pain, but people respond differently to placebo treatment. A new study from the University of Luxembourg revealed that it depends heavily on person‘s ability to reinterpret negative events and to control feelings. Interestingly, this was figured out using fMRI technology. Placebo […]

Digital storytelling helps people with dementia trigger memories

For Myrna Caroline Jacques, digital storytelling is her way of fighting Alzheimer’s. “I thought maybe if I do this and use my brain, the disease won’t take over as soon. “That’s my goal,” the 77-year-old grandma of five said. She may be onto something. A recent UAlberta study on digital […]

Stem Cell Treatment for Children With Spina Bifida Helps Dogs First

A pair of English bulldog puppies are the first patients to be successfully treated with a unique therapy — a combination of surgery and stem cells — developed at the University of California, Davis, to help preserve lower-limb function in children with spina bifida. Because dogs with the birth defect […]

Two-step process leads to cell immortalization and cancer

A mutation that helps make cells immortal is critical to the development of a tumor, but new research at UC Berkeley suggests that becoming immortal is a more complicated process than originally thought. The key to immortalization is an enzyme called telomerase, which keeps chromosomes healthy in cells that divide […]

Are stem cells the link between bacteria and cancer?

Gastric carcinoma is one of the most common causes of cancer-related deaths, primarily because most patients present at an advanced stage of the disease. The main cause of this cancer is the bacterium Helicobacter pylori, which chronically infects around half of all humans. However, unlike tumour viruses, bacteria do not deposit […]

Nerve-guiding ‘labels’ may one day help re-form broken nervous connections

Scientists have identified a large group of biological ‘labels’ that guide nerves to ensure they make the correct connections and control different parts of the body. Although their research was conducted with fruit flies, the findings offer hope that we could one day reestablish nervous connections in people living with […]

Adult brains produce new cells in previously undiscovered area

A University of Queensland discovery may lead to new treatments for anxiety, depression and post-traumatic stress disorder (PTSD). UQ Queensland Brain Institute scientists have discovered that new brain cells are produced in the adult amygdala, a region of the brain important for processing emotional memories. Disrupted connections in the amygdala, […]

Scientists identify a new way to activate stem cells to make hair grow

UCLA researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research, led by scientists Heather Christofk and William Lowry, may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss […]

Link between biological clock and aging revealed

Scientists studying how aging affects the biological clock’s control of metabolism have discovered that a low-calorie diet helps keep these energy-regulating processes humming and the body younger. In a study appearing today in the journal Cell, Paolo Sassone-Corsi, director of the Center for Epigenetics & Metabolism at the University of […]

Novel Stem Cell-Derived Model Created of Inflammatory Neurological Disorder

An international team of scientists, led by University of California San Diego School of Medicine researchers, has created a human stem cell-based model of a rare, but devastating, inherited neurological autoimmune condition called Aicardi-Goutieres Syndrome (AGS). In doing so, the team was able to identify unusual and surprising underlying genetic […]

Scientists restore youthful plasticity to the brains of adult mice

Like much of the rest of the body, the brain loses flexibility with age, impacting the ability to learn, remember and adapt. Now, scientists at University of Utah Health report they can rejuvenate the plasticity of the mouse brain, specifically in the visual cortex, increasing its ability to change in […]

Blocking a key enzyme may reverse memory loss

In the brains of Alzheimer’s patients, many of the genes required to form new memories are shut down by a genetic blockade, contributing to the cognitive decline seen in those patients. MIT researchers have now shown that they can reverse that memory loss in mice by interfering with the enzyme […]

Scientists prevent neurodegeneration-associated protein clumping in lab study

Scientists report in a new study that by imitating a natural process of cells, they prevented the formation of protein clumps associated with amyotrophic lateral sclerosis (ALS) and frontotemporal dementia. In lab cultures of human and yeast cells, the scientists stopped the harmful clumping of FUS proteins by exposing them […]
