Back in the good old days, most deaths were due to infectious diseases. Today, thanks to modern technology,life expectancy has increased and the pattern of deaths has changed. 

According to the CDC, today’s top ten leading causes of death only include two due toinfection. Both are infections of the lungs  - one is a mixture of infections (#3) and the other is influenza plus pneumonia (#8).

A group of Russian physicists, with the contribution from their Swiss colleagues, developed a way to use the therapeutic effect of heating or cooling the tissues due to the magnetocaloric effect. The article with the results of the work was published in the latest issue of the International Journal of Refrigeration.

A team of the Lomonosov Moscow State University scientists proposed a new way to use the magnetocaloric effect for the targeted delivery of drugs to the implants. Vladimir Zverev, one of the authors (Lomonosov Moscow State University, Faculty of Physics) claims that this is a unique method that uses a negative magnetocaloric effect.

Washington, DC--Women risk having their vitamin D levels fall when they stop using birth control pills or other contraceptives containing estrogen, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

Vitamin D is a hormone involved in the immune system and managing calcium levels in the blood. Proper calcium levels are necessary for bone health.

Mucous membrane pemphigoid is an autoimmune disease that causes inflammation and scarring in mucosal tissues. Affected individuals frequently exhibit scarring in the eye, which can lead to blindness in as many as 20% of patients. In this issue of JCI Insight, two related studies report on the underlying cause of fibrosis in the eye and implicate an important role for vitamin A metabolism. A group of researchers led by John Dart at UCLA show that the enzyme aldehyde dehydrogenase (ALDH), which produces the vitamin A metabolite retinoic acid, is elevated in mucous membrane tissue in the eye from mucous membrane pemphigoid patients.

A new study reveals that those who affiliate with the Democratic Party have different views than those who vote Republican on the following issues: the likelihood of floods occurring, adopting protection measures, and expectations of disaster relief from the government. The study was jointly conducted by VU University in Amsterdam, Utrecht University School of Economics in The Netherlands, and the Center for Risk Management and Decision Processes at the Wharton School of the University of Pennsylvania in Philadelphia, USA.

A joint University of Adelaide-Shanghai Jiao Tong University study has provided the first broad picture of the evolution and possible functions in the plant of pollen allergens.

Published in the journal Plant Physiology, the researchers believe their work may help with medical research into the reduction or prevention of allergic diseases such as asthma and allergic rhinitis (hay fever).

"During the past four decades, allergic diseases have become a global health problem," says project leader Professor Dabing Zhang, who leads the University of Adelaide and Shanghai Jiao Tong University Joint Laboratory for Plant Science and Breeding.

Cancer treatments based on laser irridation of tiny nanoparticles that are injected directly into the cancer tumor are working and can destroy the cancer from within. Researchers from the Niels Bohr Institute and the Faculty of Health Sciences at the University of Copenhagen have developed a method that kills cancer cells using nanoparticles and lasers. The treatment has been tested on mice and it has been demonstrated that the cancer tumors are considerably damaged. The results are published in the scientific journal, Scientific Reports.

For a cell in an embryo, the secret to becoming part of the baby's body instead of the placenta is to contract more and carry on dancing, scientists at EMBL have found. The study, published today in Nature, could one day have implications for assisted reproduction.

After a sperm cell fertilises an egg cell, that fertilised egg divides repeatedly, forming a ball of cells. Shortly before the embryo implants in the womb, some of those cells move inwards. These are the cells that will develop into all the baby's body parts. The cells left on the surface will become the placenta, connecting the embryo to the mother's uterus.

PHILADELPHIA - Reprogramming of the molecular pathways underlying normal metabolism is essential for T cell infection-fighting function and for the immune system to form a "memory" of the microbes it has already encountered. But exactly how metabolism in exhausted T cells is maintained in chronic infections and cancer is a missing element in this line of research. Now, a new study suggests that tweaking metabolic steps in combination with checkpoint blockade drugs may improve some cancer therapies, according to new research from the Perelman School of Medicine at the University of Pennsylvania. The team published their findings this week in Immunity.
