Investment risk for energy infrastructure construction is highest for nuclear power plants, lowest for solar

The average energy project costs 40% more than expected for construction and takes almost two years longer than planned, finds a new global study. One key insight: The investment risk is highest for nuclear power plant construction and lowest for solar. The researchers analyzed data from 662 energy projects built between 1936 and 2024 in 83 countries, totaling $1.358 trillion in investment. Read more ›

Genomic data shows widespread mpox transmission in West Africa prior to 2022 global outbreak

Historically, most human mpox infections have resulted from zoonotic transmission --m eaning from animals to humans -- and these spillovers have rarely led to human-to-human transmission. But during the 2022 global outbreak, mpox began spreading readily between people. A new study now shows the virus was circulating long before then. Read more ›

Not one, but two massive black holes are eating away at this galaxy

Astronomers searching for massive black holes shredding stars found one in an unusual place -- 2,600 light years from the core of a galaxy. The roque black hole may be from an earlier merger with another galaxy, or have been tossed out of the core after interacting with two other black holes. This is the first ever optically discovered off-nuclear tidal disruption event. Eventually, the two could merge and produce... Read more ›

Waist-to-height ratio predicts heart failure incidence

Risk of heart failure (HF) has been shown to increase as body mass index (BMI) increases; however, BMI has limitations as an obesity measure. Over median follow-up of 13 years, waist-to-height ratio (WtHR) was found to significantly predict incident HF in almost 2,000 individuals in the Malm Preventive Project. WtHR may be a better metric than BMI to identify patients with HF who could benefit from targeted obesity interventions. Read more ›

Survival trick: Pathogen taps iron source in immune cells

The body defends itself against pathogens by depriving them of vital iron. However, this strategy doesn't always succeed against Salmonella. Researchers have discovered that these bacteria specifically target iron-rich regions within immune cells to replicate. Their findings on how pathogens evade the immune defense are important for fighting infections. Read more ›

After cardiac event, people who regularly sit for too long had higher risk of another event

People who were less active, with a daily average of more than 14 hours of sedentary behavior, were more than twice as likely to have another cardiac event, including heart attack, surgery to treat heart issues (coronary revascularization), or to be hospitalized again within a year after the first cardiac event.

Researchers take AI to 'kindergarten' in order to learn more complex tasks

We need to learn our letters before we can learn to read and our numbers before we can learn how to add and subtract. The same principles are true with AI, a team of scientists has shown through laboratory experiments and computational modeling. In their work, researchers found that when recurrent neural networks (RNNs) are first trained on simple cognitive tasks, they are better equipped to handle more difficult and... Read more ›
