Retro-Bit has announced that the next in their line of retro reproductions/reissues/special editions is 1995’s Majyūō (sometimes translated as Majuu Ou). Previously only released in Japan on the Super Famicom, Retro-Bit will be localizing the game for the first time in an official capacity. It’s being localized as Majyūō – King of Demons, which feels pretty appropriate. This is perhaps Retro-Bit’s raddest deep cut yet. You play as Abel, who is trying to save his daughter from demons. He starts off as this regular-looking…

Recent research highlights a significant lack of awareness among young male gym-goers regarding the impact of their lifestyle, particularly protein supplement use, on fertility. The study underscores the need for better understanding and education about male reproductive health and the risks associated with certain gym supplements.Three out of four people would alter their exercise routines or supplement usage if they were aware of its long-term impacts.Many young men who frequent the gym are often not fully informed…

Researchers at Michigan State University have discovered that the cytoplasmic droplet in sperm is crucial for storing proteins vital for fertility, controlled by a protein trafficking system influenced by the SYPL1 gene. This breakthrough could have significant implications for fertility research and control.Researchers at Michigan State University have unraveled the enigma of a lesser-understood sperm structure known as the cytoplasmic droplet (CD). The CD, characterized by an enlarged cytoplasm—a viscous, gelatinous…

Rutgers University research teams have discovered key factors in predicting egg cell viability and identified a gene mutation linked to miscarriage, providing valuable insights for improving IVF success and understanding female infertility.Two studies led by Rutgers provide insights into the success and failure of egg cells.Scientists researching the challenge of high miscarriage rates have been exploring whether it’s possible to determine if an egg cell will develop successfully into an embryo or if there is a marker…

The purpose of the current trial is to assess the gel’s safety and longevity, not how well it prevents pregnancy. Participants were asked to use a back-up form of birth control while being enrolled in the trial.The gel is designed to dissolve at the end of its lifetime, so the men will be followed for two years to determine how long it takes for that to happen. Eisenfrats says the goal is to have a product that lasts one to two years.But men might want to restore their fertility before that time frame, so Contraline wants…

Recent research indicates that higher lifetime estrogen exposure, marked by longer pregnancy and reproductive periods, may reduce the risk of cerebral small vessel disease in postmenopausal women, pointing to the significance of reproductive history in brain health management. New research, recently published in Neurology, the medical journal of the American Academy of Neurology, suggests that individuals with higher lifelong estrogen exposure might be at a reduced risk for cerebral small vessel disease. This condition,…

Scientists revealed its developmental mechanism for the first time.A research team, led by Professor Toru Miura from the University of Tokyo, shows how the expression of developmental genes in the Japanese green syllid worms, Megasyllis nipponica, helps form their swimming reproductive unit called stolon.The Unique…

Meanwhile, Hanna’s team in Israel was growing mouse embryo models in a similar way, as they described in a paper in Cell that was published shortly before the paper from Zernicka-Goetz’s group. Hanna’s models too were made solely from embryonic stem cells, some of which had been genetically coaxed to become TSCs and XEN cells. “The entire synthetic organ-filled embryo, including extra-embryonic membranes, can all be generated by starting only with naive pluripotent stem cells,” Hanna said.Hanna’s embryo models, like those…

The new paper is the result of herculean computational analyses, involving researchers in Germany, Spain, and the United Kingdom, to better understand the role ancient retroviruses play in early embryonic development—how they harm, and how they help. It sprang from work Singh had done as a PhD student at the Max Delbrück Center in Berlin, when he gathered datasets from 11 studies to painstakingly trace individual embryonic stem cells from fertilization to implantation.He ran an analysis that grouped cells based on the…

According to WHO guidelines, if a doctor conscientiously objects to providing an abortion, then that country’s health system must refer a patient to an alternative health care provider. But mandatory referrals are a poor fix and conscientiously objecting health care professionals are also often reluctant to reliably refer patients to someone who will provide necessary care. Hoctor says this systemic failure to ensure backup providers is one of the main reasons behind poor access in certain European countries, including…
