A new study finds that coral reefs are more vulnerable to weakening due to ocean acidification and global warming, especially in developing countries. Effective local management efforts can help maintain coral resilience while carbon emissions are stabilized.
Scientists from Scripps Research Institute have discovered a new type of RNA molecule, called riboswitches, that can turn genes on or off in response to cellular energy needs. These findings may have implications for designing new antibiotics against harmful bacteria.
Researchers found up to 500,000 tons of gaseous hydrocarbons emitted into the deep ocean during the Deepwater Horizon oil discharge, leading to small-scale zones of oxygen depletion. The study highlights the difficulty in separating gas-induced oxygen depletion from that due to liquid hydrocarbons.
Scientists have discovered a genetic partnership between two proteins that enables nerve cells to connect correctly in the brain. The study suggests that similar mechanisms may play a role in human brain development and could lead to new therapies for developmental disorders.
Researchers recreated ancient Egyptian artificial toes and tested them on volunteers, finding they could help with walking. The toes date from before 600BC, predating the Roman Capula Leg as the earliest known practical prosthesis.
A study published in Neurology found that men who eat berries regularly have a lower risk of developing Parkinson's disease. Flavonoids, particularly anthocyanins from berries, were associated with a reduced risk in both men and women.
A study published in The Arts in Psychotherapy found that women with anorexia or bulimia draw themselves with distinct characteristics, including a larger neck and emphasized mouth. Self-figure drawings can be used as a tool for assessing eating disorders and may help individuals open up to therapists about their struggles.
UBE4B is a molecule that binds to p53 and MDM2, allowing them to degrade the tumor-suppressing protein p53 in cancer cells. This discovery could lead to novel anti-cancer therapies and improve prognosis for cancer patients.
Researchers at Northwestern University have discovered the first evidence of a human DNA fragment in a bacterial genome, specifically Neisseria gonorrhoeae. This finding offers insight into the bacterium's ability to adapt to its human host and could lead to new strains of the disease.
Researchers at Johns Hopkins University and Brookhaven National Laboratory measured superconducting fluctuations in a superconductor, finding they disappear 10-15 Kelvin above the transition temperature. This suggests electron pairs lose coherence rather than break apart at Tc, driving the transition to a non-superconducting state.
