How Do Women Compete For Partners?

Posted by in categories: biological, sex

Joyce Benenson is a lecturer of Human Evolutionary Biology at Harvard University who’s research focuses on human social structures and sex differences in competition and cooperation. We’re often told that men are more competitive, more status-driven and more ruthless with rivals for potential mates. In reality doesn’t seem to be true, the difference is that women’s competition takes a more subtle, cynical and sophisticated route to drive away their competitors. Expect to learn how women compete for status, why women exclude more than men, why women who promote an egalitarian world are less charitable than you might think, how you can interfere with a rivals’ relationship without getting caught, the usefulness of gossip as an enforcement mechanism and much more…

Startup Working on Space Babies, But the Risks Are Grim

Posted by in categories: sex, space

If humans intend to conquer the stars and spread civilization beyond Earth, we really need to figure out sex: can humans conceive and have babies in places such as Mars, where factors like high amounts of radiation and lower gravity could wreck the adult body, nevermind potentially hindering natural conception and deforming growing fetuses?

A growing number of researchers and entrepreneurs want to tackle those questions. Take this startup called Spaceborn United, which we’ve blogged about previously.

The company is still hard at work, according to new reporting from AFP, with the aim of having a baby naturally conceived and born on Mars in the future.

Higher Risk of Alzheimer’s in Women Linked to Immunity and Metabolism

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

Cleveland Clinic researchers analyzed genes and brain tissue of patients with Alzheimer’s and found that differences in brain immunometabolism – the interactions between the immune system and the ways cells create energy – may contribute to women’s increased risk for the disease and its severity.

The findings, published in Alzheimer’s and Dementia, offer important insight into developing sex-specific treatment and prevention options for Alzheimer’s disease, the sixth-leading cause of death in the United States.

“Our immune systems depend on communication between different cell types in our bodies, which are fueled by energy created from unique metabolic processes,” said Justin Lathia, Ph.D., vice chair of the Department of Cardiovascular and Metabolic Sciences and co-author on the paper. “As sex influences both the immune system and metabolic process, our study aimed to identify how all of these individual factors influence one another to contribute to Alzheimer’s disease.”

Key processes required for the different stages of fungal carnivory by a nematode-trapping fungus

Posted by in categories: food, sex

Nutritional deprivation triggers a switch from a saprotrophic to predatory lifestyle in soil-dwelling nematode-trapping fungi (NTF). In particular, the NTF Arthrobotrys oligospora secretes food and sex cues to lure nematodes to its mycelium and is triggered to develop specialized trapping devices. Captured nematodes are then invaded and digested by the fungus, thus serving as a food source. In this study, we examined the transcriptomic response of A. oligospora across the stages of sensing, trap development, and digestion upon exposure to the model nematode Caenorhabditis elegans. A. oligospora enacts a dynamic transcriptomic response, especially of protein secretion–related genes, in the presence of prey. Two-thirds of the predicted secretome of A. oligospora was up-regulated in the presence of C. elegans at all time points examined, and among these secreted proteins, 38.5% are predicte.

What OpenAI shares with Scientology

Posted by in categories: robotics/AI, sex

Ms. McCauley and Ms. Toner [HF — two board members] have ties to the Rationalist and Effective Altruist movements, a community that is deeply concerned that A.I. could one day destroy humanity. Today’s A.I. technology cannot destroy humanity. But this community believes that as the technology grows increasingly powerful, these dangers will arise.

McCauley and Toner reportedly worried that Altman was pushing too hard, too quickly for new and potentially dangerous forms of AI (similar fears led some OpenAI people to bail out and found a competitor, Anthropic, a couple of years ago). The FT’s reporting confirms that the fight was over how quickly to commercialize AI

The back-story to all of this is actually much weirder than the average sex scandal. The field of AI (in particular, its debates around Large Language Models (LLMs) like OpenAI’s GPT-4) is profoundly shaped by cultish debates among people with some very strange beliefs.

Twitter CEO Says She Wishes Elon Musk’s AI Would Talk About Sex With Her Kids

Posted by in categories: Elon Musk, humor, robotics/AI, sex

Twitter CEO Linda Yaccarino regrets that she was not able to use her boss Elon Musk’s wildly vulgar AI chatbot to teach her kids about sex. You know, regular stuff for an exec to say publicly!

To back up for a second: Grok, as the AI is called, was released this weekend to a small group of test users. Whereas other chatbots like OpenAI’s ChatGPT and Google’s Bard have been criticized by many on the right for being too liberal, Grok is specifically designed to be anti-“woke,” like a seasoned Twitter troll; it has the humor of a 13-year-old boy, and yet somehow a 53-year-old man. Unsurprisingly, the limited users with access quickly took to X-formerly-Twitter to share the AI’s sometimes tame-ish, sometimes deranged outputs with their followers.

One of those posts, shared to X on Tuesday by Babylon Bee staffer Ashley St. Clair and reshared by Musk, featured Grok’s response to the question of how babies are made.

Genetic variant in CACNA1C is associated with PTSD in traumatized police officers

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

In this study we aimed to detect epigenetic and genetic loci associated with PTSD in a homogeneous cohort of traumatized police officers. Both a genome-wide and hypothesis-driven replication approach did not result in DMPs between PTSD patients and trauma-exposed controls. GSE analysis on the top 100 DMPs showed, however, a plausible association of the dopaminergic neurogenesis pathway with PTSD. Furthermore, we observed one DMR located at the PAX8 gene suggesting consistent hypermethylation in PTSD patients. Genetic analyses yielded three CpG-SNPs significantly associated with PTSD. Of these, one CpG-SNP, located at the CACNA1C locus, was also significantly associated with PTSD in an independent replication sample of trauma-exposed children. Notably, this result shows that the Illumina 450K array is not restricted to epigenetic surveys but can provide informative genetic data as well.

Although our sample was small, it was highly homogenous as all participants were former or current police officers, and cases and controls were matched for sex, age, education, and years of police service. All participants reported multiple prior traumatic events, without significant group differences in reported types of traumatic experiences. PTSD patients fulfilled current diagnostic criteria for PTSD, while our trauma-exposed controls had minimal PTSD symptoms and did not report lifetime PTSD or other trauma-related psychiatric disorders. Thus our controls were apparently resilient to adverse mental health outcome of trauma. This study design, including extreme phenotypes following similar trauma load, was considered to favor detection of PTSD-associated loci, as also suggested by others [22]. Nevertheless, our genome-wide survey clearly remains limited in statistical power.

Immune system aging can be revealed by CT scan of thymus, research suggests

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

The thymus, a small and relatively unknown organ, may play a bigger role in the immune system of adults than was previously believed. With age, the glandular tissue in the thymus is replaced by fat, but, according to a new study from Linköping University, the rate at which this happens is linked to sex, age and lifestyle factors. These findings also indicate that the appearance of the thymus reflects the aging of the immune system.

“We doctors can assess the appearance of the thymus from largely all chest CT scans, but we tend to not see this as very important. But now it turns out that the appearance of the thymus can actually provide a lot of valuable information that we could benefit from and learn more about,” says Mårten Sandstedt, MD, Ph.D., at the Department of Radiology in Linköping and Department of Health, Medicine and Caring Sciences, Faculty of Medicine and Health Sciences, Linköping University.

The thymus is a gland located in the upper part of the chest. It has been long known that this small organ is important for immune defense development in children. After puberty, the thymus decreases in size and is eventually replaced by fat, in a process known as fatty degeneration. This has been taken to mean that it loses its function, which is why the thymus has for a long time been considered as being not important in adult life.

AI Can Screen for Diabetes

Posted by in categories: biotech/medical, food, health, mobile phones, robotics/AI, sex, time travel

In America, roughly 40 million Americans have diabetes and about 95% of them have type 2 diabetes. Type 2 diabetes occurs when the body cannot correctly process sugar and fuel cells. More specifically, the body does not produce enough insulin to break down sugar into glucose for the cells to use. In this case, treatment includes insulin shots or a pump in addition to a strict diet excluding sweets or high fat meals. Treatment limitations disrupt patient quality of life. Some researchers have been working on better detection for diabetic retinopathy with artificial intelligence (AI), but research is limited on how to better detect diabetes itself. Thus, many researchers are working to detect diabetes early on and discover better treatments.

Klick labs, located in multiple cities across the world, is trying to detect type 2 diabetes by having a patient speak into a microphone for 10 seconds. Klick labs believes this technology can better detect diabetes and help patients get treatment earlier. The study was published in Mayo Clinic Proceedings: Digital Health, which details how patients spoke for 10 seconds and combined with health data, including age, sex, height, and weight, created an AI model that discerns whether a person has type 2 diabetes or not. After further tests, scientists determined it has 89% and 86% accuracy for women and men, respectively.

In the study, Klick Labs collected voice recordings of 267 people, either non-diabetic or diabetic. The participants were asked to record a phrase into their smartphones six times a day for a total of 2-weeks. Over 18,000 recordings were taken and analyzed to distinguish 14 acoustic features that helped distinguish non-diabetic to type 2 diabetic individuals. The research highlights specific vocal variations in pitch and intensity that could lead to how the medical community screens for early-onset diabetes. A major barrier to early detection includes time, travel, and cost, which many people do not have. Voice diagnosis can help eliminate those barriers and improve detection and treatment in diabetic patients.
