Risk Factors for Young-Onset Dementia

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

Investigators identified 15 factors that affect risk for young-onset dementia.

Limited data are available on risk factors for young-onset dementia. In this study, researchers assessed 39 potential risk factors for young-onset dementia from data in the UK Biobank. Participants 65 years of age or older without a dementia diagnosis were included in the analysis. Potential risk factors were grouped into sociodemographic factors, genetic factors, lifestyle factors, environmental factors, blood marker factors, cardiometabolic factors, psychiatric factors, and other risk factors.

Among 359,052 participants, the mean age at baseline was 55 years and 55% were women. There were 485 incident all-cause young-onset dementia cases after a mean follow-up of 8 years. Incident young-onset dementia increased with age and was more common in men. Fewer years of formal education, lower socioeconomic status, the presence of two apolipoprotein E ℇ4 alleles, no alcohol use, alcohol use disorder, social isolation, vitamin D deficiency (1 mg/dL), lower handgrip strength, hearing impairment, orthostatic hypotension, stroke, diabetes, heart disease, and depression were associated with higher risk for young-onset dementia in fully adjusted models. Men with diabetes were more likely to have young-onset dementia than men without diabetes, and women with high C-reactive protein were more likely to have young-onset dementia than women with low C-reactive protein levels.

Astronaut captures stunning images of a snowy Grand Canyon

Posted by in category: space

In the final days of his six-month stint aboard the International Space Station (ISS), Danish astronaut Andreas Mogensen took some time out of his science work to snap some striking photos of a snow-covered Grand Canyon.

The images were captured from the station in recent days as it orbited Earth at an altitude of around 250 miles.

Researchers set new world record for CIGS solar cells

Posted by in categories: solar power, sustainability

Uppsala University is the new world record holder for electrical energy generation from copper indium gallium selenide (CIGS) solar cells. The new world record is 23.64% efficiency. The measurement was made by an independent institute, and the results are published in Nature Energy.

The record results from a collaboration between the company First Solar European Technology Center (formerly known as Evolar) and solar cell researchers at Uppsala University.

“The measurements that we have made ourselves for this solar cell and other solar cells produced recently are within the margin of error for the independent measurement. That measurement will also be used for an internal calibration of our own measurement methods,” says Marika Edoff, Professor of Solar Cell Technology at Uppsala University, who is responsible for the study.
