Iceotope study says liquid immersion is viable for hyperscale disk storage
Liquid cooling company Iceotope has conducted a study with Meta into the feasibility of using its technology to meet the cooling requirements of the high-density storage drives that are increasingly being deployed by hyperscale datacenter operators.indicates that immersion cooling offers benefits including reduced vibration and equalized temperature across a JBOD array, in addition to improved thermal management.
Rotating drives would not normally be considered for immersion-based cooling techniques as these typically call for all moving parts, such as fans, to be removed in order for a system to be completely submerged in coolant. Solid state drives are usually fitted instead. However, for some customers such as hyperscale operators and high-performance computing sites, the sheer volumes of data that they store and handle make it currently too costly to use just SSDs, and instead high-capacity hard drives are still very much in use. According to, more than 90 percent of the data in cloud datacenters is held on HDDs, and the remainder on SSDs.
As the volume of data generated keeps increasing, this means more storage is needed. Disk drive makers have been to deliver ever greater capacity, which translates into more power being used and therefore the heat they generate, Iceotope said. But the introduction of helium-filled hard drives over the last decade has not only improved disk performance , it means that the units are now sealed, opening the possibility of using liquid cooling with them.

Pandemic stress physically aged teens' brains, study findsA new study from Stanford University suggests that pandemic-related stressors have physically altered adolescents' brains, making their brain structures appear several years older than the brains of comparable peers before the pandemic. The study was published on Dec. 1, 2022, in Biological Psychiatry: Global Open Science.

Plasma metabolomic profiling of dietary patterns associated with glucose metabolism status: The Maastricht Study - BMC MedicineBackground Glucose metabolism has been reported to be affected by dietary patterns, while the underlying mechanisms involved remain unclear. This study aimed to investigate the potential mediation role of circulating metabolites in relation to dietary patterns for prediabetes and type 2 diabetes. Methods Data was derived from The Maastricht Study that comprised of 3441 participants (mean age of 60 years) with 28% type 2 diabetes patients by design. Dietary patterns were assessed using a validated food frequency questionnaire (FFQ), and the glucose metabolism status (GMS) was defined according to WHO guidelines. Both cross-sectional and prospective analyses were performed for the circulating metabolome to investigate their associations and mediations with responses to dietary patterns and GMS. Results Among 226 eligible metabolite measures obtained from targeted metabolomics, 14 were identified to be associated and mediated with three dietary patterns (i.e. Mediterranean Diet (MED), Dietary Approaches to Stop Hypertension Diet (DASH), and Dutch Healthy Diet (DHD)) and overall GMS. Of these, the mediation effects of 5 metabolite measures were consistent for all three dietary patterns and GMS. Based on a 7-year follow-up, a decreased risk for apolipoprotein A1 (APOA1) and docosahexaenoic acid (DHA) (RR 0.60, 95% CI 0.55, 0.65; RR 0.89, 95% CI 0.83, 0.97, respectively) but an increased risk for ratio of ω-6 to ω-3 fatty acids (RR 1.29, 95% CI 1.05, 1.43) of type 2 diabetes were observed from prediabetes, while APOA1 showed a decreased risk of type 2 diabetes from normal glucose metabolism (NGM; RR 0.82, 95% CI 0.75, 0.89). Conclusions In summary, this study suggests that adherence to a healthy dietary pattern (i.e. MED, DASH, or DHD) could affect the GMS through circulating metabolites, which provides novel insights into understanding the biological mechanisms of diet on glucose metabolism and leads to facilitating prevention strategy for type 2 diabetes.
