Each year, pests eat more than one-fifth of the crops grown around the world. Many farmers turn to insecticides to protect their harvest, but some opt for a gentler approach: They perfume their crops with behavior-influencing chemicals called pheromones that can confuse insects and prevent them from finding mates. But the high price of pheromones—commercial products can cost $400 per hectare—has prevented the widespread adoption of the tactic. Now, a new, cheaper method of…

One of the easiest and most effective editing tools you can use on iPhone and iPad is the crop tool. Cropping photos changes the size and shape, helping you create media for specific outlets like Instagram or TikTok, as well as removing unwanted elements from the edge of your shot. This can be done on photos you've taken on your device, or on photos you're editing from a different camera like a DSLR. Here's everything you need to know. How to automatically crop photos in Photos on iPhone and iPadLaunch the Photos…

Canon launched the EOS R7 and R10 APS-C RF-S mount cameras earlier this year, finally introducing lens compatibility between crop-sensor and full-frame mirrorless cameras. That puts the future of its current APS-C EOS-M line in doubt, however. Today’s review is all about the higher-end $1,500, 32-megapixel EOS R7. At that price, it goes up against rival APS-C models like Fujifilm’s X-T4 and the Sony A6600, but also Panasonic’s $1,700 Micro Four Thirds GH5-II and even full-frame cameras like Nikon’s $1,300 Z5.

Planting more crops isn't the only way to feed a growing population. Cutting air pollution could go a long way towards increasing crop production while saving precious land and money, according to new research.  If the world cuts the emissions of just one type of air pollutant in half, estimates suggest winter crops could yield about 28 percent more in China and up to 10 percent more in other parts of the world. The pollutants in question are oxides of nitrogen, a family of invisible, poisonous gasses produced by car…

Because seeds may contain yield-reducing fungi, bacteria or viruses, they're often chemically treated before they're sold to farmers. A new mobile system, however, substitutes microbe-killing electrons for harsh and eco-unfriendly chemicals.The problem with existing chemical treatments lies in the fact that the fungicides and antibacterial compounds deposited onto the seeds may be harmful both to farmers, and to the environment in which the seeds are planted.As far back as the 1980s, scientists began looking into using…
