Lab animals deficient in vitamin D crave and become dependent on opioids, which is curbed when normal levels of the vitamin are restored. Human health records indicate that people with low vitamin D are more likely to use and misuse opioids. Study results suggest a potential role for vitamin D supplementation in fighting opioid addiction.
New discovery shows human cells can write RNA sequences into DNA

In a discovery that challenges long-held dogma in biology, researchers show that mammalian cells can convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells.
Edge of Pine Island Glacier's ice shelf is ripping apart, causing key Antarctic glacier to gain speed

Pine Island Glacier's ice shelf lost about one-fifth of its total area between 2017 and 2020, in three dramatic collapses. Meanwhile the glacier sped up by 12 percent. The rest of the ice shelf, the authors say, could disappear much sooner than previous studies had suggested.

Gene expression patterns associated with pandemic viral infections provide a map to help define patients' immune responses, measure disease severity, predict outcomes and test therapies -- for current and future pandemics.
An omega-3 that's poison for tumors
- ScienceDaily
- 21/6/11 17:08
3D tumors that disintegrate within a few days thanks to the action of a well-known omega-3 (DHA, found mainly in fish) -- this is a promising discovery. Hungry for fatty acids, tumor cells in acidosis gorge themselves on DHA but are unable to store it correctly and literally poison themselves. The result? They die.
A better understanding of 'wet markets' is key to safeguarding human health, biodiversity
- ScienceDaily
- 21/6/11 14:56
The term 'wet market' is often laced with negative undertones, especially in light of the COVID-19 pandemic, but the majority of these markets -- like the one featured above in Taipei, Taiwan -- pose very little risks to human health and biodiversity, according to a new study.
Fashion for pointy shoes unleashed plague of bunions in medieval Britain
- ScienceDaily
- 21/6/11 14:56
Researchers analysing skeletal remains in the city of Cambridge find a dramatic increase in 'hallux valgus' around the time that pointed shoes became de rigueur in the 1300s. They also uncover a link between this minor deformity and increased risk of fractures.

Astronomers have spotted a giant 'blinking' star towards the centre of the Milky Way, more than 25,000 light years away.
Star's death will play a mean pinball with rhythmic planets
