Structural Approach to Cancer

This year, more than 60,000 adults in the United States will be diagnosed with pancreatic cancer and, statistically, as few as 10 percent will survive five years after diagnosis, according to the American Cancer Society. Because pancreatic cancer is hidden deep within the body and often symptomless, it’s frequently diagnosed […]

Scientists identify small-molecule cocktail to improve stem cell use in research and disease treatments

Researchers at the National Institutes of Health have devised a four-part small-molecule cocktail that can protect stem cells called induced pluripotent stem cells (iPSCs) from stress and maintain normal stem cell structure and function. The researchers suggest that the cocktail could enhance the potential therapeutic uses of stem cells, ranging […]

Traffic-related pollution linked to early markers for cardiovascular disease in children

Daily exposure to auto emissions during childhood may set the stage for cardiovascular disease in later life, according to a USC Children’s Health Study that followed 70 children into young adulthood. The research, published in the journal Environmental Health, used ultrasound to examine the carotid arteries in participants at age 10 […]

New drug class gives hope to some ovarian cancer patients

A study published in Nature Communications shows that the drug rucaparib has been effective in treating certain types of ovarian cancers if used early in treatment, after a diagnosis, and before the cancer cells build up a resistance to chemotherapy. Rucaparib is in a relatively new class of drugs – Poly(ADP-ribose) polymerase or […]

Chemical ‘nose’ sniffs critical differences in DNA structures

Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they’ve been extremely difficult to detect — until now. Using what they describe as a “chemical nose,” UC Riverside chemists are able to “smell” when bits of DNA are folded in unusual ways. […]

Researchers develop new smell test for Parkinson’s, Alzheimer’s and COVID-19

A new smell test developed by Queen Mary University of London researchers has been found to be easy to use in patients with Parkinson’s disease, and could also be helpful in diagnosing COVID-19 in the broader population. Smell tests have the potential to support the diagnosis of certain neurological conditions, […]

Prior SARS-CoV-2 infection rescues B and T cell responses to variants after first vaccine dose

A single dose of vaccine boosts potent responses against SARS-CoV-2 coronavirus variants in those with previous COVID-19, a study has found. In those who have not previously been infected and have so far only received one dose of vaccine the immune response to variants of concern may be insufficient. The […]

Genetics, not environment of the uterus, controls abnormal development

Yale researchers have shown that developmental abnormalities, including those that lead to pregnancy loss and autism, are controlled by the genetics of the fetus and placenta — and not the mother’s intrauterine environment. The findings are reported in the online edition of the journal Placenta. One out of every 33 […]

Project to read genomes of all 70,000 vertebrate species reports first discoveries

It’s one of the most audacious projects in biology today—reading the entire genome of every bird, mammal, lizard, fish, and all other creatures with backbones. And now comes the first major payoff from the Vertebrate Genomes Project (VGP): near complete, high-quality genomes of 25 species, including the greater horseshoe bat, […]

The micro-environment of breast cancer in three dimensions

Cancerous tumors thrive on blood, extending their roots deep into the fabric of the tissue of their host. They alter the genetics of surrounding cells and evolve to avoid the protective attacks of immune cells. Now, Penn State researchers have developed a way to study the relationship between solid, difficult-to-treat […]

Ingredient in Indian Long Pepper Shows Promise Against Brain Cancer in Animal Models

Penn scientists use cryo-electron microscopy to illuminate how piperlongumine works against glioblastoma. Piperlongumine, a chemical compound found in the Indian Long Pepper plant (Piper longum), is known to kill cancerous cells in many tumor types, including brain tumors. Now an international team including researchers from the Perelman School of Medicine […]

Breaking the egg barrier: A sperm story

Sperm doesn’t shift into high gear in mammals just to show off, new research shows. It originally needed that extra speed to break the egg barrier. Later on, evolution enabled sperm to use its souped-up swimming to navigate tricky reproductive pathways even before reaching the egg. That is the finding […]
