Bill Gates doesn't make vaccines. There are now 176 vaccines from many different countries, thirty four of those already in clinical trials and eight in phase 3. Some may be approved soon, and none are made by the Bill and Melinda Gates foundation.

The Bill and Melinda Gates foundation does provide funding for some vaccines. In particular they are amongst the funders for the vaccine alliances GAVI and COVAX, the vaccine pillar of the “Access to COVID19 Tools” ACT accelerator.

In late March of 2020, the Food and Drug Administration gave Emergency Use Authorization (EUA) for the malaria drug hydroxychloroquine as a treatment for COVID-19. The drug is already used off-label for diseases like arthritis and given how it behaves with human biology, it is plausible it might work on some with COVID-19. A peer-reviewed study found just that - but it was only epidemiology, and that is not how drug approval ever happens, any more than epidemiology alone should be how regulations happen at EPA or any policy-making group. 
The Andromeda galaxy, our nearest large galactic neighbor, has been found to have a nearly invisible halo of diffuse plasma that extends about halfway to our Milky Way.

That's 1.3 million light-years, and it may go 2 million light-years in some parts, which means Andromeda's halo is already touching our own. The halo has a layered structure, with two main nested and distinct shells of gas. These reservoirs of gas contain fuel for future star formation within the galaxy, as well as outflows from events such as supernovae. 
With racial tension erupting again, parents may be wondering the appropriate age to discuss what kids see in news accounts or in protests at sporting events. 

Psychologists believe that some infants are aware of race and children are capable of thinking about all sorts of complex topics at a very young age. They must, because they see older, bigger people doing things that may seem almost magical, and it becomes important to make sense of their world and so they will come up with their own ideas about how things work. But if they only see news on television, with two sides rioting and committing violence in the name of opposing the others' fascism, the ideas kids come up with may be inaccurate or even detrimental.

The false vacuum collapse is about a remote possibility, not just billions of years in the future, so far in the future that all the stars in the night sky have run out of fuel, long before.

There is no realistic possibility at present, or for billions of years, and it is of no concern.

You've probably gotten a summer cold, perhaps even the flu, even though the weather is warm.

SARS-CoV-2, the 2019 form of coronavirus that caused the COVID-19 pandemic, is in the same family as the common cold, so it is correct that heat will kill it, but just like colds and flu, weather is not a magic bullet.

Some do believe that with summer heat social distancing means less but that isn't reliable. False confidence can have adversely shaped risk perception and put people you know in the .03 with devastating risk factors in greater jeopardy.

People often adopt vegetarian or even vegan diets because they are told it will make them healthier, but the same epidemiological correlation that tried to link butter with heart disease claimed trans fats would prevent it, and now statistical links claim just the opposite. 
Muons are very special particles. They are charged particles that obey the same physical laws and interaction phenomenology of electrons, but their 207 times heavier mass (105 MeV, versus the half MeV of electrons) makes them behave in an entirely different fashion.

For one thing, muons are not stable. As they weigh more than electrons, they may transform the excess weight into energy, undergoing a disintegration (muon decay) which produces an electron and two neutrinos. And since everything that is not prohibited is compulsory in the subnuclear world, this process happens with a half time of 2 microseconds.
Researchers are on the hunt for a COVID-19 vaccine to eliminate the need for mask wearing and current limits on interpersonal gatherings (except protests), but a new model says it still may not help the world exit a lingering economic depression.
One problem with studies that create an outcome and then find data to support it is they don't have real world application. International Agency for Research on Cancer epidemiologists, for example, have been caught creating a desired warning label for chemicals and then hand-picking studies to support that goal - the opposite of what scientists do. Harvard TS Chan School of Public Health is frequently criticized for data dredging, where they take questionnaires with so many foods and outcomes they are sure to be able to link something and claim it has statistical power.

Yet in the real world, weedkillers don't cause cancer, neonicotinoids don't kill bees, and there are no "miracle vegetables."
