Recent studies in
Washington State,
US, have been unable
to show a significant
correlation between
culling wolf populations,
and reducing attacks on
livestock. Non-lethal
deterrence - fences, dogs,
flapping red flags - are
more effective. Of course,
the claims are being
disputed.

PREDATORS:
DOESN’T WORK

Stars are mostly hydrogen,
helium and maybe a few
specks of other elements
no heavier than iron. So
how does gold ever get
made? New research
suggests via neutron star
collisions. How much
gold? Three to 13 Earth
masses of gold. Bling.

A VERY HIGH PERSPECTIVE


Thanks to farming software business Granular, farmers will soon be able to monitor
their crops from space. Satellite imagery provider Planet will give Granular’s customers
access to daily images from 200 satellites. It’s enormously valuable data that can give
new insight into crop management.

The biggest risk to cryptocurrency users
remains having their coins or tokens stolen.
Cryptocurrency management systems are
called wallets, but function more like a keyring,
allowing the user to authorise transactions.
Software wallets running on a PC can be
compromised via keyloggers. Hardware wallets,
in contrast, are single-purpose computers that
“air gap” a user’s cryptocurreny private keys.
Prague-based Satoshi Labs created the Trezor
hardware wallet a couple of years ago, but its
interface is more “hacker” than “home user”.
Now the company has launched the
Trezor T, a full-colour touchscreen device its
developers hope will bring Bitcoin and other
cryptocurrencies to (even more of) the masses.

While it’s pricey at $250, the Trezor T is also
essentially uncrackable, thanks to sophisticated
USB management, and it supports eight
different cryptocurrencies so far.
Still not convinced? Satoshi Labs won’t
mind: the first production run is already sold
out. preorder.trezor.io
