At the end of the last ice age, algal blooms of the species Phaeocystis absorbed large quantities of carbon dioxide in the Southern Ocean and thus significantly slowed the rise of the greenhouse gas in the atmosphere. Credit: Gerhard Drebes Some 14,000 years ago, algal blooms in the Southern Ocean helped to massively reduce the global carbon dioxide content of the atmosphere—as has now been revealed by new analyses of ancient DNA published by a team from the Alfred Wegener Institute (AWI) in the journal Nature Geoscience. In the ocean around the Antarctic continent, these algal blooms had a significant…

Big Tech slumped, with Nvidia (NVDA) declining over 3% to end the week not long after releasing its highly anticipated earnings report. A key Fed-watched measure of inflation rose as expected in July, new government data showed Friday. The “core” Personal Consumption Expenditures index,…

So FTSE 250 firm Pets at Home (LSE: PETS) could seem like an obvious way to try and benefit from that long-term trend as an investor. But things are not always so simple in the stock market. Just because an area of business activity seems promising does not necessarily mean that all the companies operating in it will do well. Pets at Home has seen its share price tumble 26% over the past year. It is now…
Image source: Getty Images As an investor, I certainly like the passive income prospects offered by dividends. But while a dividend stock may dangle a juicy yield, that is never guaranteed to last. After all, a dividend can always be cut at any moment. That helps explain why, like any sensible investor, I diversify my portfolio across different investments. It also explains why I look at the source of a company’s dividend when investing. And then consider how sustainable it looks in the future. That is true for dividends of any size, although sometimes high-yield shares can present a specific…

(FFC), a Canadian joint venture between Canadian Nuclear Laboratories (CNL) and Kyoto Fusioneering.

Tesla (NASDAQ: TSLA) is a strange breed of stock. Leaving aside the eyebrow-raising antics of a, shall we say, ‘polarising’ CEO, the Austin-based firm sells cars but doesn’t resemble the other firms that sell cars. The electric vehicles (EV) behemoth boasts of an over $1trn market cap. It trades at 180 times earnings when other car firms are in the double or even single digits. It’s often said when discussing its elevated share price, but Tesla is a car company priced like a technology company. Why is this? Well, part of the stock’s premium comes from it having stolen a…
