Sexual dimorphism in skin immunity is mediated by an androgen-ILC2-dendritic cell axis

Posted by in category: sex

NIAID researchers have found that male mice have weaker immune responses to infection and microbial colonization of the skin than female mice because male sex hormones reduce the density and activation of key immune cells in skin. The findings are published in the journal Science.

Scientists are growing animals in artificial wombs. Humans might be next

Posted by in categories: biotech/medical, sex

A person who lost their uterus to cancer, for example, could have an embryo created in the lab, like in IVF, but implant it in an artificial womb for gestation, rather than using a human surrogate, which is an ethically fraught practice.

By eliminating the need for surrogacy, artificial wombs could also make it easier for gay couples to have biological children. Further on the horizon, if scientists can replicate their success creating embryos from the DNA of same-sex mice in people, any two people might one day be able to have biological children related to both of them.

Scientists Find Link Between ADHD, Depression and Hypersexuality

Posted by in categories: biotech/medical, neuroscience, sex

Although the interplay between sex and mental health is well-studied, a new study suggests there may be a complex correlation between seemingly disparate disorders.

In a new paper published in the Journal of Affective Disorders Reports, a group of Italian psychology researchers say they’ve found a correlation between attention-deficit/hyperactivity disorder (ADHD), depressive symptoms, hypomania (the clinical term for “mania” or high energy) and hypersexuality, or an intense preoccupation with sexual thoughts and acts — and that people who experience these sets of symptoms may use sex as a sort of “self-medication.”

Study coauthors Giacomo Ciocca, a sexual psychology assistant professor at Rome’s Sapienza University, and Davide Doroldi, a clinical psychologist, told PsyPost that they were inspired to look into the possible link after observing higher rates of hypersexuality among people with ADHD.

Genetic variants, neurocognitive outcomes, and functional neuroimaging in survivors of childhood acute lymphoblastic leukemia

Posted by in categories: biotech/medical, genetics, sex

A study involving long-term acute lymphoblastic leukemia (ALL) survivors found certain genetic variants related to the folate pathway, glucocorticoid regulation, and other factors were associated with impaired attention, motor skills, memory, and more. Read the article here:

Genetic predispositions may modulate risk for developing neurocognitive late effects in childhood acute lymphoblastic leukemia (ALL) survivors.

AI Determines Sex of Person From Brain Scans

Posted by in categories: biotech/medical, life extension, robotics/AI, sex

Summary: Researchers developed an artificial intelligence model that accurately determines the sex of individuals based on brain scans, with over 90% success. This breakthrough supports the theory that significant sex differences in brain organization exist, challenging long-standing controversies.

The AI model focused on dynamic MRI scans, identifying specific brain networks—such as the default mode, striatum, and limbic networks—as critical in distinguishing male from female brains.

This research not only deepens our understanding of brain development and aging but also opens new avenues for addressing sex-specific vulnerabilities in psychiatric and neurological disorders.

Scientists unlock key to reversible, non-hormonal male birth control

Posted by in categories: biotech/medical, genetics, sex

The team found that administering an HDAC inhibitor orally effectively halted sperm production and fertility in mice while preserving the sex drive.

Researchers are grappling with the challenge of developing effective male contraceptives as existing attempts to block sperm production, maturation, or fertilization have fallen short, either offering incomplete protection or leading to severe side effects.

Now, a team of researchers at the Salk Institute in the US has developed a novel approach to halting sperm production, which is both non-hormonal and reversible, marking a significant advancement in male contraception research.

This ‘guardian’ molecule may make women more vulnerable to autoimmune diseases

Posted by in categories: bioengineering, biotech/medical, genetics, sex

Women are more likely than men to have conditions such as lupus, rheumatoid arthritis, and autoimmune hepatitis (depicted above in a cellular micrograph), in which their immune response attacks healthy, functioning parts of their body. Yet the reason behind this sex-based imbalance has long eluded scientists. Now, a study published last week in proposes that a molecule associated with the X chromosome may be partly to blame. Researchers noticed that many of the proteins commonly targeted by the immune system in people with autoimmune diseases had something in common: They help a molecule called Xist carry out its function. Xist molecules act a bit like quality control inspectors for women’s extra X chromosomes, preventing them from producing a toxic amount of proteins. The scientists suspect that when immune cells encounter large bunches of these Xist-related proteins—for instance, when a dead cell spills them into the bloodstream—they may react by making antibodies to attack them throughout the body. To test the idea, the team studied genetically engineered mice in which both males and females produced Xist. Like their female counterparts, these males were also at an increased risk of developing severe cases of lupus. The researchers also found that people with autoimmune disorders had more antibodies for Xist-related proteins in their blood. Still, Xist molecules may not be the only factor at play: Experts note that some people produce these Xist-related antibodies without developing autoimmune disorders, reports.
