Comments Off on BMW confirms the i4 electric sedan will arrive by 2025

Ever since the i3 and i8 were released in 2014, we’ve been wondering what BMW’s next model would be for its electric i sub-brand. Now the automaker has confirmed it will introduce a new electric sedan — the i4 — by 2025. And it will be one of 25 new electrified vehicles they will launch by 2025. Even though 2025 is still a few years away, we’ve already seen a preview of the BMW i4, which will take inspiration from the i Vision Dynamics concept that made its debut last year. It is an aggressively styled sedan that’s about the same size as BMW’s popular 3 Series. If the i4 stays within that size range, it will be a direct rival to the Tesla Model 3.

It can also reach 62 mph in a quick four seconds on its way to a top speed over 120 mph. Can you say power? BMW has already confirmed that a new MINI electric car and an electrified version of the X3 SUV, called the iX3 will arrive before the i4, so there’s still plenty to look forward to. + BMW All images © BMW

Simple genetic modification causes crops to need 25% less water

Comments Off on Simple genetic modification causes crops to need 25% less water

Scientists have discovered that a simple genetic modification may result in crops needing up to 25 percent less water than unaltered plants to produce the same yield. An international team led by scientists at the University of Illinois identified a specific protein called Photosystem II Subunit S (PsbS), which can be altered to encourage a plant to partially close its stomata, the small pores that facilitate gas exchange between plants and their environment. The scientists hypothesized that the closing of stomata would allow plants to retain more water without sacrificing its need for carbon dioxide, the atmospheric concentration of which has increased by 25 percent in less than a century. Stephen Long, study co-author and director of Realizing Increased Photosynthetic Efficiency (RIPE), the international research project behind the study, said in a statement: “Evolution has not kept pace with this rapid change, so scientists have given it a helping hand”. As the world adapts to climate change , less water-intensive crops could be a game changer. “This is a major breakthrough,” explained Long. “Crop yields have steadily improved over the past 60 years, but the amount of water required to produce one ton of grain remains unchanged—which led most to assume that this factor could not change. Proving that our theory works in practice should open the door to much more research and development to achieve this all-important goal for the future.” Related: How fungi made Earth’s atmosphere livable – new study Approximately 90 percent of the world’s freshwater supply is used for agricultural purposes. As populations grow and resources become strained, more efficient plants could be a simple yet effective tool to sustain healthy communities. The research team published their positive results on the modification of a tobacco plant; their next step is to do the same for food crops. “Making crop plants more water-use efficient is arguably the greatest challenge for current and future plant scientists,” said study co-author Johannes Kromdijk in a statement . “Our results show that increased PsbS expression allows crop plants to be more conservative with water use, which we think will help to better distribute available water resources over the duration of the growing season and keep the crop more productive during dry spells .” Via New Atlas Images via University of Illinois
