National estimates of gender-affirming surgery

JAMA Network Open

2023-08-23
(Press-News.org) About The Study: In this study of 48,000 patients, gender-affirming surgery increased significantly in the U.S., nearly tripling from 2016 to 2019. Breast and chest surgery was the most common class of procedures performed overall. The number of genital surgical procedures performed increased with increasing age.  

Authors: Jason D. Wright, M.D., of the Columbia University College of Physicians and Surgeons in New York, is the corresponding author.

Health claims and doses of fish oil supplements

2023-08-23
About The Study: The results of this study suggest that the majority of fish oil supplement labels make health claims, usually in the form of structure/function claims, that imply a health benefit across a variety of organ systems despite a lack of trial data showing efficacy. Significant heterogeneity exists in the daily dose of eicosapentaenoic acid + docosahexaenoic acid in available supplements, leading to potential variability in safety and efficacy between supplements. Authors: Ann Marie Navar, M.D., ...

Study: Atmospheric circulation weakens following volcanic eruptions

2023-08-23
The Pacific Ocean covers 32% of Earth’s surface area, more than all the land combined. Unsurprisingly, its activity affects conditions around the globe. Periodic variations in the ocean’s water temperature and winds, called the El Niño–Southern Oscillation, are a major meteorologic force. Scientists know that human activity is affecting this system, but are still determining the extent. A new study in Nature has revealed that the atmospheric component of this system — ...

How artificial intelligence gave a paralyzed woman her voice back

2023-08-23
Researchers at UC San Francisco and UC Berkeley have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.    It is the first time that either speech or facial expressions have been synthesized from brain signals. The system can also decode these signals into text at nearly 80 words per minute, a vast improvement over commercially available technology.     Edward Chang, MD, chair of neurological surgery at UCSF, who has worked on the technology, known as a brain computer interface, or BCI, for more than a decade, hopes this latest research breakthrough, appearing Aug. 23, 2023, ...

Wildlife overflow enriches biodiversity beyond park boundaries

Wildlife overflow enriches biodiversity beyond park boundaries
2023-08-23
New research has discovered the power of large national parks to not only enhance bird diversity inside their borders but boost mammal diversity in nearby unprotected areas. The University of Queensland’s Dr Matthew Luskin said the study, which involved using more than 2,000 cameras and bird surveys across Southeast Asia, reveals for the first time the benefit of expanding protected land areas around the globe beyond park boundaries. “Protected area expansions are often a difficult and expensive process, but our results show they are absolutely worth it,” Dr Luskin said. “We ...

Graphene: More magic starts when flatness ends

2023-08-23
Researchers from The University of Manchester and the University of Warwick finally solved the long-standing puzzle of why graphene is so much more permeable to protons than expected by theory. A decade ago, scientists at The University of Manchester demonstrated that graphene is permeable to protons, nuclei of hydrogen atoms. The unexpected result started a debate in the community because theory predicted that it would take billions of years for a proton to permeate through graphene’s dense crystalline structure. This had led to suggestions that protons permeate not through the crystal lattice itself, ...

Researchers fully sequence the Y chromosome for the first time

Researchers fully sequence the Y chromosome for the first time
2023-08-23
What was once the final frontier of the human genome — the Y chromosome — has just been mapped out in its entirety.    Led by the National Human Genome Research Institute (NHGRI), a team of researchers at the National Institute of Standards and Technology (NIST) and many other organizations used advanced sequencing technologies to read out the full DNA sequence of the Y chromosome — a  region of the genome that typically drives male reproductive development. The results of a study ...

New research shows how cancer rewires a key immune pathway to spread

New research shows how cancer rewires a key immune pathway to spread
2023-08-23
A study led by researchers at Memorial Sloan Kettering Cancer Center (MSK) and Weill Cornell Medicine discovered a new relationship between cancer cells and the immune system, and shows how cancer can selfishly hijack a normally helpful immune pathway. Usually, activation of this key immune pathway — called the STING pathway — triggers a strong inflammatory response that protects the body from foreign and unhealthy cells. But prolonged activation of the same pathway leads to a desensitization and ultimately to a “rewiring” of cellular signaling, which aids and abets cancer’s spread, the researchers found. “You might think of ...

Adding immunity to human kidney-on-a-chip advances cancer drug testing

Adding immunity to human kidney-on-a-chip advances cancer drug testing
2023-08-23
By Benjamin Boettner (Boston) — A growing repertoire of cell and molecule-based immunotherapies is offering patients with indomitable cancers new hope by mobilizing their immune systems against tumor cells. An emerging class of such immunotherapeutics, known as T cell bispecific antibodies (TCBs), are of growing importance with several TCBs that the U.S. Food and Drug Administration (FDA) approved for the treatment of leukemias, lymphomas, and myelomas. These antibody drugs label tumor cells with one of their ends, and attract immune cells with another end to coerce them into tumor cell killing. One major challenge in the development of TCBs and other immunotherapy ...

Fungus gnats as pollinators not pests

Fungus gnats as pollinators not pests
2023-08-23
Many plants and crops rely on insects to pollinate them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded ...
