Having 35 copies of the CAG triplet in the gene that causes Huntington’s disease is not a problem. Inheriting 40 could be a sign that goes unnoticed for decades, until reaching 80. From there, the process accelerates and neural death occurs when reaching 150 repeats. Huntington’s disease neurodegeneration is not determined by what, but by how much, according to a study conducted at the Broad Institute.

An experimental tuberculosis (TB) vaccine with a dual mission – self-destruction after inducing immunity – improved the design of the Bacillus Calmette-Guérin (BCG) immunotherapy, a vaccine also used against cancer. Scientists at the University of Pittsburgh engineered this strain with a double break, which is effective and safer after an intravenous administration, according to their results in nonhuman primates and mice.

Around the end of every year, the media reports on pregnancy and women who give birth on the last and first days of the new year. They tell their stories, the names of their babies and the cities where they were born. While 2024 was coming to an end, gynecologists and other researchers finalized their publications to improve the health of women and their babies. The formation of the placenta or the study of preeclampsia are some of the first and last stories that greet and say goodbye to 2024. Those of 2025 will be born soon.

Among the most profound results presented at the 2024 European Society for Medical Oncology Congress were the 10-year data from the Checkmate-067 and Keynote-006 trials of Opdivo and Keytruda as first-line agents in advanced or metastatic melanoma in which 10-year overall survival topped 40%. The success of checkpoint blockade, however, has not extended to all tumor types, but in 2024, molecular studies have led to advances in gene therapies and a multitude of approaches that have opened the door to hope.

In the 1970s, scientists from several countries proposed to reconstruct, one by one, all the neurons in the brain as they appear under an electron microscope. They started with a small worm. Caenorhabditis elegans has only 302 neurons. It took 16 years. How much time would be required to repeat this arduous task for the 100 billion neurons in the human brain?

First, the good news about pandemics – and in 2024, there was big “good news.” Science Magazine named lenacapavir (Gilead Sciences Inc.) as the Breakthrough of the Year. In two separate trials, lenacapavir prevented HIV transmission with 100% efficacy in cisgender African women and 99.9% efficacy in men and gender-diverse persons when administered twice a year.
