Poorest children have worse health and educational outcomes in adolescence

A new report reveals that children born into the poorest fifth of families in the UK are 12 times more likely to experience poor health and educational outcomes by age 17. This clustering of adverse outcomes is linked to early childhood disadvantage, with modest reductions seen when lifting families out of poverty.

Climate change threatens global fisheries

A major study found that climate change could decline the diet quality of fish by up to 10% as zooplankton communities shift towards more carnivorous groups. This could exacerbate declines in fish biomass, with potential implications for human societies relying on fisheries for food and livelihoods.

Researchers of Tokyo Metropolitan Institute of Medical Science and National Institute of Mental Health proposed that the pathological mechanism of intellectual disability caused by RP58/ZBTB18 haploinsufficiency may be a disorder of excitatory synapses

A new mouse model of RP58/ZBTB18 haploinsufficiency shows impaired motor learning, working memory, and cognitive flexibility. The study suggests that excitatory synaptic defects underlie intellectual disability caused by RP58/ZBTB18 haploinsufficiency.

New survey finds COVID-19 pandemic changed public’s view of obesity

A new survey found that nearly a third of Americans worry more about obesity due to COVID-19, with 28 million people considering weight loss methods. The survey also showed that nearly 90% with obesity have tried to lose weight at some point in their lives, but many underestimate the effectiveness of treatments like weight-loss surgery.

Big firms are failing to reduce unconscious bias against disabled people

A new study found that working for a big company or in an HR role does not lower the likelihood of showing unconscious bias against disabled people at work. Despite large firms' efforts to address EDI and unconscious bias through training, levels of implicit bias remain roughly the same across different sized companies.

Mercury emission estimates rarely provide enough data to assess success in eliminating harmful global gold mining practice

A study analyzed 25 countries' baseline mercury emission estimates and found that they rarely provide enough information to determine whether changes are due to actual change or data uncertainty. This lack of transparency hinders efforts to draft meaningful mercury reduction targets in national action plans.

Surprisingly simple explanation for the alien comet 'Oumuamua's weird orbit

Researchers Jennifer Bergner and Darryl Seligman suggest that 'Oumuamua's acceleration can be explained by the outgassing of hydrogen gas as the comet warmed up in the sunlight. The comet's small size allowed for a significant effect, with the tiny push from hydrogen spurted out of ice altering its gravitational deflection around the sun.
