☆ Perimenopause may spike risk of depression, study finds
▼ + stars: | 2024-04-30 | by ( Kristen Rogers | ) edition.cnn.com time to read: +6 min

Now, a new study has quantified the risk of depression during the transition, known as perimenopause — showing that women in this stage are about 40% more likely to experience the mental health condition than premenopausal women. The authors conducted the study — which is a review of seven studies totaling 9,141 women — to provide an estimate for the risk of developing clinical, diagnosed depression or depressive symptoms at different menopausal stages. The authors didn’t find a significant difference in risk of depression for postmenopausal women compared with premenopausal women. Badawy is now an associate graduate mental health worker at the Barnet, Enfield and Haringey Mental Health NHS Trust in London. And doctors should develop and maintain relationships with mental health providers to whom they can refer patients diagnosed with depression.

☆ Teen vaping linked with toxic lead exposure, study finds
▼ + stars: | 2024-04-29 | by ( Kristen Rogers | ) edition.cnn.com time to read: +6 min

Now, a new study, building upon previous evidence, has found that among teens, vaping often may spike the risk of exposure to lead and uranium — potentially harming brain and organ development in young people. However, chronic exposure to metals, “even at low levels, can lead to detrimental health impacts, affecting cardiovascular, renal, cognitive and psychiatric functions,” she added. The study was conducted at one point in time, so the authors couldn’t control for chronic or long-term exposure. The authors acknowledged that their study is observational, meaning it didn’t find a causal relationship between vaping and toxic metal levels. But knowing why this preference led to higher uranium exposure requires more research.

And perhaps best of all, money — from selling the electricity generated by the wind turbines studding the flat green fields stretching out to the North Sea. A slice of the cash goes to the villagers themselves, with the local buy-in making this windy farming enclave near the border with Denmark a showcase for ways to push ahead with renewable energy projects. The S&P Global Clean Energy Index of shares in companies with clean energy-related businesses has fallen 26% over the past year, even as broader market indexes have surged to records. In sub-Saharan Africa, where half the population lacks access to electricity, renewable projects face even steeper challenges with financing.

As the climate crisis continues to pose a global threat, top economists are debating its effect on the U.S. economy. Mark Zandi, chief economist at Moody’s Analytics, projects "physical risks" will be the biggest economic cost over the next 10 to 20 years. Zandi also projects transition costs associated with moving from a fossil fuel-dominated economy to one driven by green energy will put a weight on the U.S. economy. Nouriel Roubini, an economics and international business professor at New York University, says there will be pressure from stakeholders and society to make a green transition. Watch the video above to see how top economists predict the climate crisis will affect the U.S. economy.

Could President Biden, who claims to have labor-friendly policies, be the one to turn the tide by appealing to the White working class and giving his party a much-needed electoral boost in the process? After all, issues affecting poor White voters, such as health care, higher education and increased access to childcare have long been traditional Democratic priorities. That gaffe echoed Obama’s off-the-cuff remark in 2008 that “bitter” low-income voters “cling to guns or religion” — comments that didn’t endear him to the White working class, either. Some White voters of modest means perceive Democrats as being determined to secure equality for minority groups at their expense. And working-class White Americans tended for some reason not to perceive Obamacare — the president’s signature social policy achievement — as immediately benefiting them.

☆ White dwarf star has metal scar after gobbling planetary fragment
▼ + stars: | 2024-02-26 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —Astronomers have spotted an unusual sign that a dead star feasted on a fragment of a planet orbiting it: a metal scar on the star’s surface. The observation revealed a metallic feature on the star’s surface that the researchers determined was related to a change detected in the star’s magnetic field. The strength of the metal detection also synced with changes observed in the star’s magnetic field, which led the team to determine that the metal scar was located on one of the star’s magnetic poles. The star’s magnetic field pulled the metals toward the star, which led to the presence of the scar, the finding has suggested. But WD 0816-310 presents an entirely different scenario orchestrated by the star’s magnetic field.

All five adults had growth hormone deficiency as children and received pituitary growth hormones prepared in a specific way from cadavers. The treatment approach was discontinued after cases of a rare brain disorder called Creutzfeldt-Jakob disease were found to be associated with the administration of contaminated human growth hormone from cadavers. Although Alzheimer’s is not a prion disease, some separate research suggests that the two proteins that are hallmarks in Alzheimer’s disease — amyloid beta and tau — behave like prions. “This study suggests that in very rare circumstances Alzheimer’s disease may be transmitted between humans via human growth hormone from deceased donors. “I’m also intrigued by how these results may inform potential therapeutic targets and strategies in the future,” Isaacson said, regarding Alzheimer’s disease.

Scientists based in Australia have found that mouse-sized male antechinus trade sleep to leave more time for reproductive activities during mating season, with one male who was monitored halving his sleep time during that period. Non-breeding dusky antechinus spend an average of 15.3 hours of the day asleep, according to the researchers. “Sleep restriction in breeding male antechinus is likely to be an adaptive behavioral response driven by strong sexual selection,” the paper said. To study the semelparous marsupials, researchers examined two antechinus species: dusky antechinus (Antechinus swainsonii) and wild agile antechinus (Antechinus agilis) both captive and wild. Lesku said researchers would next like to examine how male antechinus deal with restricting their sleep for three weeks.
