The mass death of sea creatures in Russia’s Kamchatka region was caused by toxins from microalgae rather than man-made pollution, a senior Russian scientist said on Monday, citing preliminary findings of an investigation.
Locals on the volcanic peninsula in the Pacific raised the alarm in September as surfers experienced stinging eyes and sea creatures, including octopuses, seals and sea urchins, were found dead on the shore.
Scientists suggested that up to 95 percent of marine life living along the seabed in the affected area had died.
Conservation activists had raised concern that the source of the pollution could be a Soviet era storage ground for poisonous chemicals on Kamchatka that might have seeped out into the sea.
“I am sure that we are facing a large-scale phenomenon, but not an uncommon one for Kamchatka, called harmful blooming algae,” the vice president of Russia’s Academy of Sciences, Andrei Adrianov, told journalists

- Several bird species in the Bahamian islands were lost or displaced after humans arrived
- Researchers say the human impact is the “most likely culprit” for the losses
- The others that survived are said to be more resilient but they still need to be protected
Did the early humans really have a more harmonious relationship with the environment? A new study found that human arrival in the Bahamian islands actually led to the loss and displacement of several bird species.
Humanity today is facing an extinction crisis, which many believe is caused by human actions quite unlike the previous mass extinctions that were caused by natural events. These actions include overfishing, deforestation, pollution and the burning of fossil fuels.
Does this necessarily mean those earlier humans without the tools for massive deforestation and harnessing fossil fuels were more harmonized with the environment? According to a new study, maybe

The finding may explain why nearly half of people who get COVID-19 experience few or no symptoms, even though they are able to spread the disease, according to the study’s corresponding author Rajesh Khanna, PhD, a professor in the College of Medicine — Tucson’s Department of Pharmacology.
“It made a lot of sense to me that perhaps the reason for the unrelenting spread of COVID-19 is that in the early stages, you’re walking around all fine as if nothing is wrong because your pain has been suppressed,” said Dr. Khanna. “You have the virus, but you don’t feel bad because you pain is gone. If we can prove that this pain relief is what is causing COVID-19 to spread further, that’s of enormous value.”
The paper, “SARS-CoV-2 Spike protein

Obstructive sleep apnea (OSA) is a chronic sleep condition affecting more than one billion people worldwide. Evidence suggests OSA can alter the gut microbiome (GM) and may promote OSA-associated co-morbidities, including diabetes, hypertension and cognitive problems. Researchers from the University of Missouri School of Medicine and MU Health Care have discovered how OSA-related sleep disturbances affect the gut microbiome in mice and how transplanting those gut bacteria into other mice can cause changes to sleep patterns in the recipient mice.

David Gozal, MD, the Marie M. and Harry L. Smith Endowed Chair of Child Health at the MU School of Medicine, said the study shows the gut microbiome plays a major role in sleep regulation. This ultimately could translate into treatments that target the gut microbiome in humans with OSA.
“By manipulating the gut microbiome, or the byproducts of the gut microbiota, we would be in a position to prevent
