The success of clownfish families linked to high-quality habitats, not shared genes

In a study published today, scientists report that the long-term success of clownfish depends more on living in a good neighborhood than it does on good genes.

Few things to know before buying at-home genetic testing kits

At-home genetic testing kits, also known as direct-to-consumer or lab-to-consumer DNA tests, are growing in popularity - especially as holiday gifts.

Broadly expressed metabolic approach could make sarcoma susceptible to targeted therapies

Soft tissue sarcoma cells stop a key metabolic process which allows them to multiply and spread, and so restarting that process could leave these cancers vulnerable to a variety of treatments.

New way to thwart HIV infection at early stages

1.7 million. That's how many people are infected with the human immunodeficiency virus (HIV) each year worldwide. 1.7 million people who are condemned to lifelong antiretroviral therapy (ART) or risk developing fatal AIDS . Out of the 37.9 million people living with HIV (PLWH), 22.3 million have access to ART, allowing them to have an almost normal lifespan.

Newly developed personalized vaccine system could delay onset of pancreatic cancer

Researchers from Queen Mary University of London and Zhengzhou University have developed a personalized vaccine system that could ultimately delay the onset of pancreatic cancer. The study provides strong proof-of-concept for the creation of a vaccine for cancer prevention in individuals at high risk of developing this disease and to slow down tumor growth in patients who are affected by it.

Studying the genomes of hibernating mammals could improve understanding and treatment of obesity

A discovery about mammalian genomes and hibernation could aid understanding and treatment of obesity and metabolic disorders.

Fertility treatments cause epigenetic changes in mouse embryos, study finds

Though epigenetic disorders - diseases caused by faulty gene expression - are still rare overall, babies born using fertility treatments have up to an 11-fold higher risk of inheriting them.

Diabetes curriculum may help empower students to make healthy choices

For Lola McPherren, learning about diabetes is personal. The Juanita High School ninth-grader had a grandfather with diabetes. She recalled that he gave himself a shot of insulin before a meal, and that he also never really changed his diet to help control the disease. He died in February.

Glaucoma risk increased by air pollution

The more polluted the air, the higher the risk is that those who live in that area will develop glaucoma, says an interesting new study from the UK, published today in the journal Investigative Ophthalmology and Visual Science.

Researchers discover cellular origins of pediatric brain tumors

A research team led by Dr. Claudia Kleinman, an investigator at the Lady Davis Institute at the Jewish General Hospital, together with Dr. Nada Jabado, of the Research Institute of the McGill University Health Centre, and Dr. Michael Taylor, of The Hospital for Sick Children, discovered that several types of highly aggressive and, ultimately, fatal pediatric brain tumors originate during brain development.

New antiviral drug drives treatment resistance in influenza viruses

On January 31, 2019, an 11-year old boy in Japan went to a medical clinic with a fever. The providers there diagnosed him with influenza, a strain called H3N2, and sent him home with a new medication called baloxavir.

Discovery in C. difficile biology opens new window to developing treatments for dangerous infections

A process called sporulation that helps the dangerous bacterium Clostridium difficile (C. difficile) to survive inhospitable conditions and spread is regulated by epigenetics, factors that affect gene expression beyond the DNA genetic code, researchers at the Icahn School of Medicine at Mount Sinai report.

Scientists discover new approach to treating incurable leukemia in children

Acute lymphoblastic leukemia (ALL) is a form of blood cancer that primarily affects children and young people.

New electrochemical CRISPR biosensor can help improve diagnosis of diseases

The CRISPR/Cas technology can do more than alter genes. A research team at the University of Freiburg is using what are known as gene scissors - which scientists can use to edit genetic material - in order to better diagnose diseases such as cancer.

Article reveals new mechanism of programmed aging

Nature has sentenced humans to an inevitable death from the time of birth; the natural instrument of execution is the aging process. According to modern scientific notions, only two root causes of aging can be: stochastic physiological damage or the implementation of a special genetic program in the body.

Recent discovery about C. difficile could pave the way for new treatments

Researchers have found that sporulation, which helps the bacterium C. difficile survive and spread, is regulated by epigenetics.

Study shows how drinking patterns reprogram circadian metabolism in the liver

Drinking alcohol is a widespread habit in modern society and can have serious metabolic consequences. Recent studies have uncovered the interplay between nutrition, metabolism and circadian rhythms. But, until now, little has been done to understand the effects of alcohol consumption on circadian metabolism.

Discovery enables strategies to be developed for preventing malaria transmission

The bacteria that form the gut microbiota influence important processes of the human body, such as digestion, nutrient absorption, and defense against pathogens. The same type of relationship is present in most animals, including in the Anhopheles darlingi mosquito, the main vector of malaria in Brazil.
