Top science# 4 We’ve measured the size of Venus’s planetary core for the first time:

Top science# 5 A recent study reported an alarming answer: In the six months after an infection, one in three people had experienced a psychiatric or neurological diagnosis. But it’s not clear whether the virus causes these disorders directly.:

The vast majority of those diagnoses were depression and anxiety, “disorders that are extremely common in the general population already,” points out Jonathan Rogers, a psychiatrist at University College London. © ScienceNews. May 4 2021 Reported Here.

Top science# 7 A wristband that turns body heat into electricity can power an LED:

The researchers hope to improve performance by increasing the size of the TEG on the wristband and integrating a voltage converter to enable it to power larger electronics – though they point out that doing so will require increasing the size of the whole device. © newscientist.

Top science# 19 A fossil of an organism that lived a billion years ago is the oldest to have two recognisable types of cells making up its inside and outside:

It may have been one of the first life forms built that way, making it a crucial step towards modern organisms like animals that also have a skin that is distinct from the cells inside the body. © newscientist. May 4 2021 Reported Here.


Top science# 20 Lingering questions — what the virus actually does to the brain, who will suffer the most, and for how long — are still unanswered, and probably won’t be answered for a long time.:
