Water has varied in temperature for as long as water has existed and it seems evolution has provided coral reefs a recovery mechanism after variation results in 'bleaching' - when corals expel algae and turn white. It can have some impact beyond algae because about 275 million people live near a coral reef and they can be tourist attractions and help support fishing industries.

In 2018, two years after the government protected Chagos Archipelago underwent bleaching, the reef coral cover and carbonate production were down by more than 70 percent. Yet by last year, they were found to have rebounded nicely. 

South-East Asia is a substantial consumer of rice but also accounts for about 40 percent of international rice exports. Before population plateaus some time after 2050, and as globalization makes the world more prosperous, there will likely be 18 percent higher demand for rice in the region.

Bad dietary habits start young, as do most bad habits, from smoking to drug use. Good habits tend to be the same. It is known that movement on a regular basis keeps kids healthy but a new study found that physical fitness is also linked to concentration and health-related quality of life for primary school pupils.

Though activists will highlight mass shootings as a gun problem rather than a criminal act, as in a Sacramento, California shooting a few days ago, legal California gun ownership has had an inverse relationship to crime and deaths. More guns than ever are owned but there are fewer gun deaths per capita.

A recent trial of lamivudine, a reverse transcriptase inhibitor used in HIV therapy, found that it stopped disease progression in patients with fourth-line metastatic colorectal cancer. 

The trial included 32 patients with advanced metastatic colon cancer whose disease progressed despite four lines of previous cancer treatments. The first nine patients received the standard HIV-approved dose of lamivudine. After adjusting the dosing four-fold, another 23 patients received lamivudine therapy where it was highly tolerated.

In an Instagram post, the family of Bruce Willis revealed that the actor has been diagnosed with aphasia, and the cognitive decline resulting means he is stepping away from his acting career.

Aphasia is devastating for an actor because all three kinds - Broca's aphasia, Wernicke's aphasia, and global aphasia - mean a loss of communications ability. And when an actor has to struggle to communicate at all, they are losing the ability to act.
