Plus: This company is developing gene therapies for muscle growth, erectile dysfunction, and "radical longevity" For decades, lithium-ion batteries have powered our phones, laptops, and electric vehicles. But lithium's limited supply and volatile price have led the industry to seek more resilient alternatives. They work much like lithium-ion ones: they store and release energy by shuttling ions between two electrodes. But unlike lithium, a somewhat rare element that is currently mined in only a handful of countries, sodium is cheap and found everywhere. Read why it's poised to become more important to our energy future. Sodium-ion batteries are one of 10 Breakthrough Technologies this year.

It might seem a little convenient coming from a group of highly educated scientists. But researchers now say that geeks make better romantic partners than any muscle-bound meathead. In a new study, scientists from Oakland University claim that intelligent men have better relationship outcomes and are less likely to be abusive towards their partners. And, in good news for nerds, the researchers even claim that smarter men are less likely to suffer from erectile dysfunction. The scientists tested the intelligence of men in heterosexual relationships and then surveyed them for a range of different positive or negative relationship traits.

It's well known that spending too much time gaming could lead to weight gain and trouble sleeping. However, it could spell trouble in the bedroom, a study suggests. Researchers in China studied more than 200,000 men while they performed'leisure' activities like watching TV, going for a drive, and playing games on the computer. The team measured participants' sex hormones, as well as feelings of depression and anxiety. They found that every 1.2 hours spent playing video games or doing other leisure activities per day at the computer led to a three times greater risk of erectile dysfunction (ED).

While the 10-year survival rate for localized prostate cancer patients is very good (>98%), side effects of treatment may limit quality of life significantly. Erectile dysfunction (ED) is a common burden associated with increasing age as well as prostate cancer treatment. Although many studies have investigated the factors affecting erectile dysfunction (ED) after prostate cancer treatment, only limited studies have investigated whether ED can be predicted before the start of treatment. The advent of machine learning (ML) based prediction tools in oncology offers a promising approach to improve accuracy of prediction and quality of care. Predicting ED may help aid shared decision making by making the advantages and disadvantages of certain treatments clear, so that a tailored treatment for an individual patient can be chosen. This study aimed to predict ED at 1-year and 2-year post-diagnosis based on patient demographics, clinical data and patient-reported outcomes (PROMs) measured at diagnosis.
