Brain Alterations Make It Difficult for Parkinson’s Disease Patients to Turn While Walking

The ability to turn while walking is impaired among patients with Parkinson's disease. This difficulty is also associated with freezing of gait and falls, which can have devastating medical consequences in an older population. A new Tel Aviv University study advances the understanding of turns in Parkinson's patients, providing new insights into […]

This New Biochip Can Detect Beginning Stages of Disease in Your Body

Some of the deadliest cancers have mostly silent symptoms. By the time people go to their doctors because of worrisome changes, cancer may have already reached a late stage, giving physicians limited treatment options. Scientists are always looking for ways to detect cancer and other diseases through tests that show […]

A step toward recovering reproduction in girls who survive childhood cancer

Leukemia treatments often leave girls infertile, but a procedure developed by researchers at the University of Michigan working with mice is a step toward restoring their ability to be biological mothers. Ovarian follicles are the “nests” that carry eggs and support them to grow and become viable. The researchers demonstrated […]

A New Biological Aging Clock: Ribosomal DNA

Chronological aging is easy to track – birthdays. Biological aging can be obvious too – graying hair, sagging skin, and other inexorable signs of impending decrepitude. But measuring biological aging isn’t as easy as noting the passage of time. The best-studied measure of biological age is the shrinking of chromosome tips, or telomeres, […]

Lifespan Links

Scientists have known for decades that caloric restriction leads to a longer lifespan. It has also been observed that chronic inflammation increases with age. But any relationship between the two had remained unexplored. But in a new study, published in Cell Metabolism,  Harvard Medical School researchers at Joslin Diabetes Center have uncovered […]

Immunotherapy Kicks, Kills HIV by Exploiting a Common Virus

In a first on the quest to cure HIV, University of Pittsburgh Graduate School of Public Health scientists report in EBioMedicine that they’ve developed an all-in-one immunotherapy approach that not only kicks HIV out of hiding in the immune system, but also kills it. The key lies in immune cells designed to recognize an […]

Witnessing the dance of RNAs around droplets of cellular degradation machinery

If a picture’s worth a thousand words, a video is perhaps worth much more. For the first time, scientists have observed a dynamic localization of a single RNA with processing bodies—the membraneless organelles present in the cytoplasm of nearly all mammalian cells that play an important role in RNA regulation. […]

DTU develops breast cancer scanning equipment

DTU has entered into collaboration with the UK company Kromek aimed at developing a scanner that can improve breast cancer diagnostics. Advanced technology developed for space research often has great potential in other fields. The new industrial research and development partnership between DTU Space and the UK company Kromek Group plc is a good […]

Older women have the highest risk of dying from cervical cancer

New research from Aarhus University and Aarhus University Hospital shows that women aged 65 and older have a higher risk of dying from cervical cancer than previously thought – although this age group is not covered by the Danish screening programme. Denmark has one of highest incidences of cervical cancer […]

Alzheimer’s Diagnosis, Management Improved by Brain Scans

A first-of-its-kind national study has found that a form of brain imaging that detects Alzheimer’s-related “plaques” significantly influenced clinical management of patients with mild cognitive impairment and dementia. The study revealed that providing clinicians with the results of positron emission tomography (PET) scans that identify amyloid plaques in the brain […]

The Doctor and the Machine

A 49-year-old man notices a painless rash on his shoulder but doesn’t seek care. Months later, during a routine physical, his doctor notices the rash and diagnoses it as a benign skin condition. More time passes, and during a routine screening test, a nurse points out the rash to another […]

Computational model of a human kinase may provide insights for cancer treatment

Researchers have developed a computational model for human MEK1, a protein with potential as a drug target for a variety of human cancers. The initiation and progression of cancer cells occur when molecular signals involved in cellular proliferation go awry. MEK1 plays an essential role in signaling within both healthy […]

Urine Test to Evaluate Immunotherapy Success Gets $1.8 Million NIH Research Grant

New immunotherapies can dramatically defeat cancer. But more often, cancer evades them, and doctors need to know quickly when that happens, so they can adjust treatment. An experimental urine test to detect immunotherapy effectiveness very early has received a major funding boost. The National Institutes of Health has granted $1.8 […]

Scientists prod immune cells to attack pancreatic cancer

It's possible to prod immune cells to attack and kill pancreatic cancer cells, according to a report from scientists at the University of Washington School of Medicine and the Fred Hutchinson Cancer Research Center in Seattle.  Their findings challenge the commonly held view that pancreatic cancer does not elicit an immune system response that […]

Scientists create world’s first gene-edited lizards

A group of University of Georgia researchers led by geneticist Douglas Menke has become the first in the world to successfully produce a genetically modified reptile—specifically, four albino lizards—using the CRISPR-Cas9 gene-editing tool. The team’s results, which appeared online, have been submitted for peer review. “Reptiles are very understudied in terms […]

How Immune Cells Help Tumors Escape Body's Defenses

New research from the University of Pittsburgh School of Medicine and the UPMC Hillman Cancer Center sheds light on how tumors use the body’s regulators of immunity for their own benefit. Published in Nature Immunology, the findings could be used to develop the next generation of immune therapies to fight various cancers. “While cancer immunotherapy […]

Metastatic prostate cancer may have its own biomarker, UB research finds

Prostate cancer can grow slowly and pose little threat to patients, or it can metastasize quickly, causing severe pain and death. But as of now, it’s nearly impossible to determine which type of cancer a patient has during the early stages. Now, University at Buffalo researchers and scientists from Moscow […]

Laser Technology Helps Researchers Scrutinize Cancer Cells

Devising the best treatment for a patient with cancer requires doctors to know something about the traits of the cancer from which the patient is suffering. But one of the greatest difficulties in treating cancer is that cancer cells are not all the same. Even within the same tumor, cancer […]
