The 'Graying' of T Cells

The elderly suffer more serious complications from infections and benefit less from vaccination than the general population. Scientists have long known that a weakened immune system is to blame but the exact mechanisms behind this lagging immunity have remained largely unknown. Now research led by investigators at Harvard Medical School […]

NIH scientists find that breast cancer protection from pregnancy starts decades later

In general, women who have had children have a lower risk of breast cancer compared to women who have never given birth. However, new research has found that moms don’t experience this breast cancer protection until many years later and may face elevated risk for more than 20 years after […]

New cervical cancer test has 100 per cent detection rate

A new test for cervical cancer was found to detect all of the cancers in a randomised clinical screening trial of 15,744 women, outperforming both the current Pap smear and human papillomavirus (HPV) test at a reduced cost, according to a study led by Queen Mary University of London. The […]

Regrowing damaged nerves hinges on shutting down key genes

Neurons in the brain and spinal cord don’t grow back after injury, unlike those in the rest of the body. Cut your finger, and you’ll probably be back to using it in days or weeks; slice through your spinal cord, and you likely will never walk again. Now, working in […]

Study links frequent red meat consumption to high levels of chemical associated with heart disease

Researchers have identified another reason to limit red meat consumption: high levels of a gut-generated chemical called trimethylamine N-oxide (TMAO), that also is linked to heart disease. Scientists found that people who eat a diet rich in red meat have triple the TMAO levels of those who eat a diet […]

Moderate or severe sleep apnea doubles risk of hard-to-treat hypertension in African-Americans

African-Americans with moderate or severe sleep apnea are twice as likely to have hard-to-control high blood pressure when their sleep apnea goes untreated, according to a new study funded mainly by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. The findings, which researchers […]

Why Many Older Patients with Low Risk Still Want Colorectal Cancer Screenings

It’s a simple message, but as screening recommendations for colorectal and other cancers become more complicated, what happens when the message becomes “maybe get screened” or even “stop screening”? A new study in JAMA Network Open finds nearly one-third of veterans who underwent recommended screening colonoscopies were uncomfortable with the idea of […]

Why Every Pancreatic Cancer Patient Should Consider Genetic Testing

Genetics may play a larger role in pancreatic cancer than previously thought, an expert panel has found. It’s led to the American Society of Clinical Oncology recommending that genetic testing be offered to anyone diagnosed with pancreatic cancer. The goal: to help identify family members who might be at greater risk. “It […]

CCNY-Yale researchers make shape shifting cell breakthrough

A new computational model developed by researchers from The City College of New York and Yale gives a clearer picture of the structure and mechanics of soft, shape-changing cells that could provide a better understanding of cancerous tumor growth, wound healing, and embryonic development. Mark D. Shattuck, professor of physics at City […]

Researchers use zinc to target insulin-producing cells with regenerative drug

An insulin injection can manage diabetes symptoms, but actually curing the disease would mean healing cells in the pancreas that produce insulin, a hormone that regulates the amount of sugar in blood. One promising approach may be to stimulate the regeneration of those cells with drugs. But there’s a major […]

Receiving genetic information can alter a person’s risk

Millions of people in the United States alone have submitted their DNA for analysis and received information that not only predicts their risk for disease but, it turns out, in some cases might also have influenced that risk, according to a recent study by researchers at Stanford University. The team, […]

Rift Valley Fever is Catastrophic to Developing Fetuses

Like Zika, infection with Rift Valley fever virus can go unnoticed during pregnancy, all the while doing irreparable – often lethal – harm to the fetus. The results of a new study, led by researchers at the University of Pittsburgh Center for Vaccine Research (CVR), underscore the importance of disease prevention for […]

How does cancer spread?

How does cancer spread? While studying human brain tumour cells, a team of scientists at the Research Institute of the McGill University Health Centre (RI-MUHC) found some answers to this crucial, yet so far unanswered question. They looked at a gene called EGFRvIII, which is present in patients with glioblastoma – […]

New method for studying ALS more effectively

The neurodegenerative disease ALS causes motor neuron death and paralysis. However, long before the cells die, they lose contact with the muscles as their axons atrophy. Researchers at Karolinska Institutet have now devised a new method that radically improves the ability to study axons and thus to better understand the […]

Breast Cancer Recruits Bone Marrow Cells to Increase Cancer Cell Proliferation

Tel Aviv University researchers have discovered that breast cancer tumors boost their growth by recruiting stromal cells that originate in bone marrow. While the recruitment of bone marrow-derived fibroblasts lowers the odds of surviving breast cancer, the study suggests that targeting these cells with new therapies could be an effective way […]

Infections in children tied to subsequent mental illness risk in new study

High temperatures, sore throats and infections during childhood can increase the risk of also suffering from a mental disorder as a child or adolescent. This is shown by the first study of its kind to follow all children born in Denmark between 1 January 1995 and 30 June 2012. The […]

New gene editing tool drives stem cell services and discovery

At just two-and-a-half years old, the University of Wisconsin–Madison Human Stem Cell Gene Editing Service is already contemplating expansion. The increased demand has tracked the growth of research projects on campus using a new gene editing tool called CRISPR-Cas9. The service derives and genetically engineers pluripotent stem cell lines for […]

Can exercise delay dementia symptoms?

After reading studies that showed aerobic exercise can improve cognition in healthy adults, School of Nursing researcher Fang Yu wondered how exercise could affect people with Alzheimer’s disease and other dementias. For the last 15 years, Yu has been exploring that question from a variety of perspectives. She thinks non-pharmacological […]

Study points to optimal blood pressure treatment for stroke patients

Aggressive treatment of hypertension in stroke patients could do more harm than good in the long term, according to a new study from researchers at the University of Georgia. Sixty percent of stroke patients admitted to U.S. emergency rooms have elevated blood pressure, and many studies say that having high blood […]

A better look at how cells move

A new computational model clarifies the structure and mechanics of soft, shape-changing cells, potentially giving scientists a better understanding of cancerous tumor growth, wound healing, and embryonic development. Led by Corey O’Hern, a Yale professor of mechanical engineering and materials science, physics, and applied physics, the researchers developed an efficient computational […]

Elevated hormone flags liver problems in mice with methylmalonic acidemia

Researchers have discovered that a hormone, fibroblast growth factor 21 (FGF21), is extremely elevated in mice with liver disease that mimics the same condition in patients with methylmalonic acidemia (MMA), a serious genomic disorder. Based on this finding, medical teams treating patients with MMA will be able to measure FGF21 levels to […]

MIT engineers repurpose wasp venom as an antibiotic drug

The venom of insects such as wasps and bees is full of compounds that can kill bacteria. Unfortunately, many of these compounds are also toxic for humans, making it impossible to use them as antibiotic drugs. After performing a systematic study of the antimicrobial properties of a toxin normally found […]
