Un-decryptable — set of computer scientists has taken a major step toward this goal with the release today of EverCrypt, a set of digital cryptography tools. The researchers were able to prove ( in the sense that you can prove the Pythagorean theorem) that their approach to online security is completely invulnerable to the main types of hacking attacks that have felled other programs in the past.
~ But did they only achieve this by very strictly limiting the operational parameters?
Better solid-state batteries — Scientists in Japan have developed a complex hydride lithium superionic conductor that could result in all-solid-state batteries with the highest energy density to date.
All-solid-state batteries incorporating a lithium metal anode have the potential to address the energy density issues of conventional lithium-ion batteries. But until now, their use in practical cells has been limited by the high resistance of lithium ion transfer within anode materials.
~This should open up new fields in solid electrolyte materials.
Better pesto — Machine learning has been used to create basil plants that are extra-delicious. The effort reflects a broader trend that involves using data science and machine learning to improve agriculture.
~ I’ll wait till the machine learning learns to harvest my basil and make the pesto.
Bone loss mechanisms in post-menopausal women — Japanese researchers have found that blood serum levels of Sema3A decrease in premenopausal women as they get older and drop even further once women reach menopause, linked to oestrogen loss, and this appears to be the mechanism for weakened bones.
~ See how I didn’t use ‘Osteoporosis breakthrough’?
Even an hour of walking a week can help older adults with ailing knees — Researchers looked at data from an earlier project studying thousands of middle-aged and elderly Americans with knee osteoarthritis, the Osteoarthritis Initiative, which began in 2004. Exercise helps prevent conditions of knee osteoarthritis and improve symptoms, reduces pain, and slows down the disease’s progression.
~ I’ve always been of fan of ‘more movement, less worrying about food’.
‘New’ Californian mammoths — Mammut pacificus, a new species of mastodon specific to a small segment of the North American West, is the first new mastodon species to be recognised in 50 years.
~ There have been known examples, just not recognised as distinctive.
Four-legged Peruvian whale — The discovery of a fossilised, 42-million-year-old, four-legged whale is shedding new light on the evolution and geographical spread of these aquatic mammals.
~ The ancestors of modern whales and dolphins evolved from a small, four-limbed hoofed animal that lived in south Asia around 50 million years ago during the Eocene.
Trees almost at the Pole — Using sedimentary records and plant fossils, researchers have found that temperatures near the South Pole were about 20C higher than now in the Pliocene epoch, from 5.3m to 2.6m years ago. Then, a variety of beech and possibly conifer trees grew at Oliver Bluffs, 300 miles from the South Pole.
~ So plants may colonise that area again, at current rates.
