"Researchers have developed a skin-permeable polymer that can deliver insulin into the body, which they say could one day offer an alternative to injections for diabetes management. The skin's structure presents a formidable barrier to the delivery of large drugs but in this work a team show that their polymer can penetrate though the different layers without causing damage. Insulin attached to this polymer was able to reduce blood glucose levels in animal models for diabetes at a comparable speed to injected insulin."
"The human brain responds in a similar way to both familiar and unfamiliar languages, but there are some key differences, according to new research - a finding that may explain why learning a language can be difficult. A study looking involving 34 people showed that listening to an unfamiliar language triggers similar neural activity to listening to their native tongue."
Researchers developed a skin-permeable polymer that can deliver insulin through intact skin by penetrating multiple layers without causing damage. Insulin conjugated to the polymer lowered blood glucose in diabetic animal models at speeds comparable to injected insulin. Long-term safety remains untested and further research is required before clinical application. Additional segments report that extreme drought could become a major challenge after a huge volcanic eruption and that a bacterium can be engineered to produce a colour-changing pigment. A neuroimaging study found similar neural responses to familiar and unfamiliar languages, with subtle differences when listeners understand the language. Briefing notes suggest greenhouse-gas emissions may peak around 2030 and mention evidence of ancient dog breeding.
