Oceans’ surface waters near the equator are warmer because of El Niño, the National Oceanic and Atmospheric Administration (NOAA) said in a statement. While El Niño is not caused by global warming, its manifestation — which ranges from heavy rainfall to droughts — can be heightened by increasing temperatures worldwide. The natural recurring phenomenon, which takes place every 2-7 years, can also play a role in predicting hurricane activity, the statement notes.
New records in temperatures: Locations around the world that are already subject to elevated temperatures can record new highs because of El Niño, NOAA scientist Michelle L’Heureux was quoted as saying. The last time El Niño took place was in 2019 but its recorded effects were not significant, Space.com notes.
Importantly, this round is bringing fresh “economic destruction” to an already wobbly global economy that is still reeling from the effects of the covid-19 pandemic and Russia’s war in Ukraine, Bloomberg says. “Combined with more extreme weather and hotter temperatures due to accelerated climate change, the stage is now set for the world’s costliest El Niño cycle since meteorologists started keeping track,” the business information service says.
A complement peptide in an experimental nasal drop could help stroke patients recover faster, a study published in the Journal of Clinical Investigation reveals. Even though the treatment has only been tested on mice, it has shown that the peptide successfully increased the number of connections in the nerve cells inside the rodents’ brains — improving their functionality, among other advantages.
The drops can be administered seven days after a stroke, which could open up a new avenue for recovery for stroke victims who have missed their window for thrombolysis (an injection to break up blood clots) or thrombectomy (surgery to remove clots), as the peptide has proven to cause more damage than good if given earlier, according to the researchers. This study also forms part of a larger project that the scientists are working on to understand how this peptide can do more than just heal the impact of a stroke, but to prevent it, as well.
