Experimental compound, which has received orphan drug and pediatric rare disease designations from the FDA, displays effectiveness in treating symptoms of Autism and Alzheimer’s disease

An experimental drug called NAP has been found effective in treating a broad spectrum of symptoms related to autism, intellectual disability, and Alzheimer's disease. Researchers discovered that NAP normalizes brain function in mice modeling ADNP syndrome, a rare disorder linked to these conditions.

Prescribing the abortion pill without restrictions is safe and effective: UBC-led study

A UBC-led study found no increase in abortion-related health complications after Canada removed mifepristone restrictions. The study examined 315,000 abortions in Ontario between 2012 and 2020 and showed that abortion continued to be safe and effective with mifepristone prescribed without restrictions.

‘Would you like a little ice with your exoplanet?’ For Earth-like worlds, that may be a tall order

A team of scientists simulated over 200,000 hypothetical Earth-like worlds to understand the types of environments astronomers can expect to find on real exoplanets. They found that in 90% of cases with liquid water on the surface, there are no ice sheets, but rather permanent ice belts along the equator.

Fish help control crown-of-thorns starfish numbers on Great Barrier Reef

A new study from Australian Institute of Marine Science reveals that reef fish such as emperors, tropical snappers, and rockcods play a crucial role in controlling crown-of-thorns starfish numbers on the Great Barrier Reef. By removing these fish species, the abundance of coral-eating starfish increases.

Twitter reveals dynamics of stories surrounding Trump’s presidency

A computational analysis of billions of tweets has uncovered high-resolution timelines of the major stories surrounding Trump's presidency from 2016 to 2021. The study found that turbulence in these stories varied over time, with dominant narratives emerging for longer periods during certain periods.

The paradox of big data spoils vaccination surveys

Researchers from Harvard University and others have found that large-scale COVID-19 vaccination surveys were off by up to 17 percentage points due to systematic biases in the data. The 'Big Data Paradox' highlights how big data sets can minimize one type of error while magnifying another, leading to misleading results.

Talk therapy by US psychiatrists declined by half since 1990s

A study found that the percentage of psychiatrist visits involving psychotherapy dropped to 21.6% between 1996 and 2016, with rural and Black/Hispanic patients experiencing significant declines. The shift towards medication management is attributed to economic factors and a national shortage in psychiatric services.

Nature or nurture: How does an animal get its microbiome?

Researchers have found that sharks acquire their microbiome through three methods: the mother passing on microbes to her offspring via egg case, social interactions with other sharks, and recruiting microbes from their environment. This study provides new insights into the development of animal microbiomes and their importance in under...
