Scientists Rediscover a Rare, Wild Species That Could Save Coffee From Climate Change

Scientists Rediscover a Rare, Wild Species That Could Save Coffee From Climate Change

As the climate crisis  in temperature and rainfall patterns around the world, one of the many crops under threat is . Now scientists have identified a coffee-making plant that could be more robust against the rigors of the shifting seasons. The plant is stenophylla coffee or , a wild and relatively rare species found in Upper West Africa. Compared with the more commonly used coffee plants, it's better equipped to handle climate shifts.What's more, it has a similar flavor to high-quality Arabica coffee made from the arabica () plant, so it should keep connoisseurs of the hot beverage...

This Guy on YouTube Actually Cooked Meat by Slapping It... a Lot

This Guy on YouTube Actually Cooked Meat by Slapping It... a Lot

Ever wondered if you can cook a chicken solely from the heat generated by slapping it? So did YouTuber Louis Weisz, and the verdict is... yes. Yes, you can.As you can see from the video embedded below, the endeavor took plenty of work – two months' worth in total – from testing out the theory to constructing a super-speedy (and customizable) chicken slapper to actually getting the bird cooked. But in the end, Weisz did indeed come out with a cooked chicken at the end of it: a triumph of persistence if not really a practical option for your next camping trip.Two key considerations along the...

After 50 Years, Physicists Confirm The Existence of an Elusive Quasiparticle

After 50 Years, Physicists Confirm The Existence of an Elusive Quasiparticle

Through painstaking work, scientists have found evidence of a that was first imagined as a hypothesis : the odderon.The odderon is a combination of subatomic particles rather than a new fundamental particle – but it does act like the latter in some respects, and the way it fits into the fundamental building blocks of matter makes the discovery a huge moment for physicists. The odderon was finally revealed through a detailed analysis of two groups of data, hitting the 5 sigma chance of probability researchers use as a threshold. "This means that if the odderon did not exist, the probability...

Semi-Transparent Solar Cells Can Power Greenhouses Without Stunting Plant Growth

Semi-Transparent Solar Cells Can Power Greenhouses Without Stunting Plant Growth

Greenhouses fitted with semi-transparent solar cells can generate electricity without affecting the growth and health of the plants inside, according to a new study, suggesting we could build energy-neutral greenhouses without harming crops. Researchers tested groups of red leaf lettuce under different types of glass and different wavelengths of light, keeping all other variables the same – including temperature, CO2 concentration, and supplies of water and fertilizer.The lettuce grown under solar cells showed no major difference in any key measurement, including antioxidants, CO2...

How to Tell Which Emails Quietly Track You

How to Tell Which Emails Quietly Track You

now: political parties, your book club, , the social networks you're signed up to, your parents, that online store that you only bought one item from a decade ago, and many, many more.What do a lot of those email senders have in common? They want to know whether the messages they send you are being opened, and there are a variety of tools available to help them do just that—tools that aren't all that hard to use.A tracking pixel, embedded somewhere in the email, is how most people monitor whether an email gets opened. Once the tiny, hidden single-pixel image is loaded, it reports back to...

Engineers Have Proposed The First Model For a Physically Possible Warp Drive

Engineers Have Proposed The First Model For a Physically Possible Warp Drive

The idea of a warp drive taking us across large areas of space faster than the speed of light has long fascinated scientists and sci-fi fans alike. While we're still a very long way from jumping any universal speed limits, that doesn't mean we'll never ride the waves of warped space-time. Now a group of physicists have put together the first proposal for a physical warp drive, based on a concept devised back in the '90s. And they say it shouldn't break any of laws of physics.Theoretically speaking, warp drives bend and change the shape of space-time to exaggerate differences in time and...

How to Set Up a 4G LTE Wi-Fi Network as an Alternative to Broadband

How to Set Up a 4G LTE Wi-Fi Network as an Alternative to Broadband

us, especially in rural areas, over cable or DSL (or heaven forbid, satellite) aren't as reliable or as fast as we would like—if they're even available at all. But the increase in speed and capacity of 4G LTE () networks has opened up another option.Traditional hurdles that made this less than an ideal solution—data caps, expense, bandwidth, coverage, compatible hardware—are slowly becoming less of an issue as the technology improves, and it's now very possible to switch completely from standard broadband to 4G LTE broadband—with a few caveats and conditions.How 4G LTE Internet WorksThe...

Watch a Billion Years of Shifting Tectonic Plates in 40 Mesmerising Seconds

Watch a Billion Years of Shifting Tectonic Plates in 40 Mesmerising Seconds

The tectonic plates that cover Earth like a jigsaw puzzle move about as fast as our fingernails grow, but over the course of a billion years that's enough to travel across the entire planet – as a fascinating new video shows. In one of the most complete models of tectonic plate movements ever put together, scientists have condensed a billion years of movement into a 40-second video clip, so we can see how these giant slabs of rock have interacted over time.As they move, the plates affect climate, tidal patterns, animal movements and their evolution, volcanic activity, the production of...

Astronomers Trace Wild 22-Million-Year Journey of a Meteorite That Crashed to Earth

Astronomers Trace Wild 22-Million-Year Journey of a Meteorite That Crashed to Earth

The crashed into Earth in the Kalahari Desert on 2 June 2018 – and now scientists have been able to trace it back 22 million years to the place where it originated from. This is the first time a meteorite's entire voyage to Earth has been charted in this way, and it's only the that we've ever had the opportunity to observe an asteroid in space before it enters the atmosphere and becomes a meteor.Based on those early observations, analysis of the recovered meteorite fragments, and various other factors, a new study pinpoints the origin of 2018 LA as – the Solar System's second largest...
