Hormonal therapy to treat breast cancer is associated with a lower risk of Alzheimer's disease and dementia in women over 65, a study says. The retrospective analysis is based on data from more than 18,000 women with breast cancer in the US: two-thirds of them had received hormone therapy and one-third had not. The "protective effect" of hormone therapy declines with age and varies by ethnicity, adds the article published in JAMA Network Open.
Five out of ten potential treatments move from animal studies to human studies; four to randomised controlled clinical trials; and one in 20 moves on to approval by regulatory agencies, an analysis estimates. Concordance between positive results in animals and in clinical studies is 86%, according to the study, published in PLoS Biology, which pools the findings of 122 published studies on 54 different human diseases.
ESA's ExoMars and Mars Express missions have for the first time detected ice near the equator of Mars, specifically in the Tharsis volcanoes, an area of the planet where it was thought impossible to exist. According to the researchers, who publish the results in the journal Nature Geoscience, such findings are important for habitability and future human exploration.
According to a report published yesterday in The New York Times, most of the members of the Subcommission on Quaternary Stratigraphy had rejected the proposal to declare the beginning of the Anthropocene, thus showing their opposition to the idea that this is a new geological epoch. Other sources told El País that the result of the vote was not formally confirmed. If this proposal is defeated, the process could be restarted from scratch at a later date.
At an informative meeting organized by the Science Media Centre Spain, the coauthor of a paper published this week in the journal Cell discussed his findings with journalists. Although the study was conducted with mice, he is confident in being able to analyze human eggs to see if his conclusions could explain the loss of fertility that occurs in women with age.
An international team, led by a Spanish group, has published the mechanism that allows immature egg reserves (oocytes) to survive for many years, up to almost half a century in the case of humans. The research studies how oocytes are affected by protein aggregates similar to those that damage other cells such as neurons and can cause neurodegenerative diseases such as Alzheimer's disease. The finding of how these egg reserves are kept healthy may help to understand some causes of infertility. The results are published in the journal Cell.
This week, Spain’s Ministry of Health launched a process to develop a Royal Decree on the medical use of cannabis, assuring that it will be "a rigorous measure based on the best scientific evidence available.” The goverment is conducting a public consultation until 4 March to gather the opinions of citizens, civil society organisations, professional associations and scientific societies. In this explainer, we attempt to answer the main questions that arise regarding the medical use of cannabis.
A team of researchers has demonstrated how a non-invasive ultrasound technique can increase the movement of human sperm in the laboratory by up to 266%. Using microfluidic droplets to evaluate individual sperm cells, which had not been done before, they found that ultrasound exposure induced movement in immobile sperm and improved swimming speeds in mobile ones. The work is published today in the journal Science Advances.
In an anonymous online survey of dog owners in Denmark, 38% of respondents said they administered cannabinoid products - such as cannabidiol drops - to their pets without a prescription, even though their use is not legal in animals. Reasons given included pain, behavioural problems and allergies in their dogs. Some 2,000 people responded to the survey, the results of which are published in the journal PLoS ONE.
Fifteen years ago, the European Space Agency's (ESA) Mars Express probe revealed the presence of large deep deposits on Mars, in an area called the Medusae Fossae Formation (MFF), located at its equator. Now, new data from the probe's MARSIS radar indicate that the deposits are deeper than previously thought - up to 3.7 kilometers thick - and include both ice-rich and dusty layers. The results are published in Geophysical Research Letters.
