Plant Species in Danger of Disappearing

Guest Post by Jennifer Lynch

Plants don’t get enough credit in our world. They’re seen as lifeless decorations or a way to recycle cow manure. But plants have a magic all their own. A bouquet of flowers can patch up a couple after a fight, while a man-eating plant can play the villain in a movie or musical. Plus, they fill that minorly important role of producing food and oxygen. So while they help keep us alive, here are eight plant species that could probably use our help to survive.

  1. Hawaiian gardenia

    This small tree with white flowers is found on the islands of Lanai and Oahu in Hawaii and is also known as Nanu, though it probably has nothing to do with Mork. The trees grow to about 16 feet tall with shiny oval leaves, and the flowers have six petals. You’ve probably seen the flowers, or one of the other two types of gardenias in Hawaii, used in leis. There are thought to only be 15 or 20 trees left today, and those numbers are decreasing. Once common and found on all the main islands, the Hawaiian gardenia was used by Hawaiians for wood, dyes, and landscaping purposes.

  2. Poke-me-boy

    Though its name sounds like a Facebook come-on, the poke-me-boy is actually a spiny tree in the bean family found only on the British Virgin Islands, specifically on the island of Anegada. It produces fuzzy, yellow flowers between its long thorns. As the poke-me-boy’s tiny island habitat becomes more developed for residences and tourism, the plant is suffering quick losses. Fire is often used to clear land, and the trees are continuously under threat of natural disasters. Hurricanes, earthquakes, and floods threaten the poke-me-boys, which live barely above sea level. There are also many roaming animals on the one-town island that often trample or graze on the plant.

  3. Cabbage on a stick

    Cabbage on a stick is pretty much what it sounds like: a tuft of leaves that looks like a head of cabbage sitting on top of a thick stick. It’s also known as alula. In the wild, this plant is only found on the Hawaiian island of Kauai and without the work of botanists, it would be extinct. Because the only insect that could pollinate the cabbage on a stick, a type of hawk moth, doesn’t exist anymore, the plant species can only reproduce if humans hand-pollinate it. Botanists repelled down cliffs to reach the existing alula, pollinate it, and bring some back with them to grow in nurseries. Cabbage on a stick is still critically endangered in the wild, but can be found in plant conservatories around the world.

  4. Mun ebony

    Mun, or moon, ebony is from the same family as the black, shiny stuff that goes so well with ivory in song. But mun ebony is often striped and even more rare than black ebony. It’s found in Vietnam and possibly Laos, and is just as dense as its famous cousin. Because of its heaviness and fine texture that allows it to be polished, it has been very popular to make instruments, tools, and sculptures from it. The export of mun ebony is now banned, and some parks are protecting the ebony within them, but it may not be enough to keep ebony from disappearing into the hands of merchants and woodworkers.

  5. Golden barrel

    This plant is also known as mother-in-law’s cushion, which would be sweet except that the golden barrel is a cactus. Even though this prickly sphere is one of the most popular kinds of cacti in cultivation, it is nearing extinction in the wild. It’s found in Central Mexico, but its habitat was severely reduced in the ’90s by the construction of a dam and reservoir. The golden barrel cactus is grown all over the world in nurseries, but people continue to take the cacti illegally from the wild. Experts estimate that this plant could be extinct in the wild within 30 years. And once it’s gone, where will the in-laws sit?

  6. Virginia round-leaf birch

    This birch, the most endangered tree in North America, has already come back from the dead once. After it was first discovered in 1918, experts thought it had become extinct when they couldn’t find any more, until more birches were discovered in 1975. The tree is found in Virginia, and while there are more than 900 found in the wild as of 2006, this birch is only known to have naturally reproduced once, in the ’80s. This means the round-leaf birch is dependent on human aid to keep the species going. And humans are also a major threat to the tree; vandals and thieves have historically been attracted to the trees and seedlings, presumably because of their rarity. This is why we can’t have nice things.

  7. Large-leaved pitcher plant

    When you first see the large-leaved pitcher plant, you might think it’s just a vase of water conveniently growing in the jungle. But get too close and it could eat you — well, if you’re a bug. The pitcher plant is one kind of carnivorous plant, and this is one of the largest versions, with the pitcher often growing more than a foot deep. It’s only found on one mountain in Borneo, though, so this species faces the threat of extinction. Pitcher plants lure insects into their fluid-filled pitchers, where the insects drown and are ingested. Large-leaved pitcher plants were recently found to have the exact dimensions as tree shrews in the area, but even though the plants probably could trap and kill the rodents, it’s more likely that they are engineered to catch the shrew’s droppings for food. It’d be a pity to lose one of the only plants that gathers its own fertilizer.

  8. Capa rose

    The capa rose by any other name would probably not seem like a rose at all. It’s actually part of a family of small trees that produce small, star-shaped flowers and bright purple berries. It only grows in Puerto Rico and has trouble reproducing naturally. Deforestation and development of land for agriculture are causing its habitat to shrink even further. The capa rose’s habitat is under U.S. jurisdiction, and the Forest Service chose not to list its habitat as critical because they would have to publish details on the plant’s location, basically providing a map for people who want to collect the plant illegally.

Water Flowing On Mars

Observations from NASA’s Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars.Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars’ southern hemisphere.

“The best explanation for these observations so far is the flow of briny water,” said Alfred McEwen of the University of Arizona, Tucson. McEwen is the principal investigator for the orbiter’s High Resolution Imaging Science Experiment (HiRISE) and lead author of a report about the recurring flows published in the journal Science.

Some aspects of the observations still puzzle researchers, but flows of liquid brine fit the features’ characteristics better than alternate hypotheses. Saltiness lowers the freezing temperature of water. Sites with active flows get warm enough, even in the shallow subsurface, to sustain liquid water that is about as salty as Earth’s oceans, while pure water would freeze at the observed temperatures.

Some Most Notable Science Fair Projects

Guest Post by Kaitlyn Cole

While science fair projects still typically consist of paper mache volcanoes, LEGO robots, and crystals grown in a jar, many students these days are going above and beyond the staples, taking on projects that would even be awe-inspiring as a college thesis. From exploring the effectiveness of cancer treatments to revolutionizing the disposal of plastics, these students prove you don’t have to be an adult to have amazing, world-changing ideas about science. Take a look at these 20 amazing science fair projects we’ve listed here. They may just inspire you to step up your game in your own college-level science courses.

  1. Nuclear Fusion Reactor, Thiago Olsen:

    With a budget of only $3,500, this Michigan high school student built a nuclear fusion reactor in his garage when he was only 15 years old. How did he do it? He studied physics textbooks, used vacuum pump manuals, and surfed the web for the best deals on parts. While his device is not self-sustaining and produces fusion only on a small scale, it’s a pretty impressive feat for any teenager.

  2. Diesel Hybrid Car, West Philadelphia High School:

    Working as a team at West Philadelphia High School, students constructed a diesel-hybrid race car that can go from 0-60 in just four seconds. If that speed wasn’t already impressive enough, the vehicle also gets more than 60 miles to the gallon. The students constructed it for entry into the Automotive X contest, with a grand prize of $10 million — the only high schoolers in the nation to do so. They are reworking their design to improve their chances of winning, and hope to get the car up to 100 MPG.

  3. Chemical-Sniffing LEGO Robot, Anna Simpson:

    Many a science fair project involve LEGOs, but few on the level that Anna Simpson’s does. Her robot, built of the plastic blocks, is capable of sniffing out toxic chemicals and other hazards, keeping humans at a safe distance. Simpson’s work won her the California State Science Fair and could have a number of industrial and public safety applications if adapted.

  4. Spacecraft Navigation Software, Erika DeBenedictis:

    This bright, young rising star in the scientific community came up with some ingenious software for helping spacecraft move faster and use less fuel while navigating the many obstacles in the vacuum of space. Her amazing software won a substantial award from the Intel Foundation, and more than likely will help assure her a future career at NASA.

  5. Plastic-Eating Microbes, Daniel Burd:

    Plastic that is simply dumped into landfills can take centuries to decompose, if it ever really does, but this young thinker came up with a better way. Burd beat out leading scientists to discovering a microbe that eats plastic, increasing the rate of decomposition by more than 40%. This project won him the Canada-Wide Science Fair and garnered a fair amount of international media attention as well.

  6. Space Exploration Balloon, IES La Bisbal School:

    The students at this Spanish school produced a science fair project that was out of this world — literally. A team of four students sent a camera-operated weather balloon into the stratosphere, snagging atmospheric readings and stunning photographs more than 20 miles above the Earth’s surface.

  7. Cancer and Chicken Marinades, Lauren Hodge:

    At just 14 years old, Lauren Hodge is getting a jumpstart on a science career with this amazing project, which won her an award at the international Google Science Fair competition. So what did she find? Some chicken marinades block carcinogenic compounds from forming when chicken is grilled — a process known to raise the level of carcinogens in meat. Among the marinades she tested, lemon juice was the most successful, so consider these stellar findings the next time you’re hosting a backyard BBQ.

  8. Image-Based Search Engine, David Liu:

    While most search engines work at dissecting the web’s textual information, David Liu’s pet project is all about creating one that looks at images instead. While he is still working to perfect his software, Liu’s search engine is already being used in the real world, analyzing satellite images and making relevant web searches much more effective. An impressive feat for a 17-year-old.

  9. Problems with Ovarian Cancer Treatment, Shree Bose:

    Taking top prize at the Google Science Fair, Bose will get to spend several weeks studying marine life in the Galapagos Islands. The work that netted her this prize is awe-inspiring coming from a teenager. Bose uncovered a number of problems with popular ovarian cancer treatments and drugs, producing a report that would be more at home in a medical journal than a high school classroom. Hopefully, this will influence some changes in how treatment is doled out to suffering patients.

  10. Computer Speed Enhancing Software, Kevin Ellis:

    Slow computers are the bane of every office worker’s existence, but with the work of Kevin Ellis, an unresponsive machine may be a thing of the past. Rather than upgrading computers with more memory, Ellis has developed software that analyzes how programs are running and spreads out their needs over all the CPUs to make everything more quickly. His amazing software netted him $50,000 and the rest of the world a way to speed up computers that may have otherwise been tossed out.

  11. Quantum Computing for Difficult Computational Problems, Yale Fan:

    Despite his name, this young genius chose Harvard over Yale to continue working on his education. Part of what got him there, undoubtedly, was this impressive bit of science. Yale’s research project, titled “Adiabatic Quantum Algorithms for Boolean Satisfiability” analyzed the applications of quantum computing for solving some of the most complex and difficult computational problems. Most adults don’t have half an idea what that even means, so it’s all the more impressive that this teen was already studying it in high school.

  12. Photodynamic Cancer Therapy, Amy Chyao:

    The definitive cure for cancer is still undoubtedly a long way off, but young researchers like Amy Chyao are certainly helping in the fight with innovative new ideas. Amy’s science project used photodynamic therapy to target and kill cancer cells. The project was so promising, it garnered her the Intel International Science and Engineering Fair award in 2010.

  13. Antarctic Submersible, Ryan Garner and Amanda Wilson:

    These two teens have come up with an amazing way to do research on climate change. With a budget of $5,000, the pair built an underwater rover designed to take on the challenges of some of the harshest conditions in the world — like those at the Antarctic Circle. Equipped with a camera, the device can explore and take measurements, and is currently being used by the University of California-Santa Barbara to study marine life.

  14. Nuclear Weapon Detector, Taylor Wilson:

    Sixteen year-old Taylor Wilson began his nuclear detection project at the age of only 11. Supported by his parents and a grant from Homeland Security, he eventually created a device that can reliably detect nuclear weapons and explosive materials as vehicles pass through his drive-through sensor.

  15. Teaching Robots to Speak English, Luke Taylor:

    South African Luke Taylor submitted this amazing project to Google’s Science Fair, which lets humans communicate more easily with robots. His software translates the English language into code that the robot can then understand and execute — allowing just about anyone, anywhere to program one to perform a variety of functions. Even more impressive? Taylor is just 13 years old.

  16. Better Password Technology, Jacob Buckman:

    How many of your online passwords are truly secure? If you’re like most people, probably not many. This young man may have come up with a solution, monitoring the biometrics of how people type to create a more secure way of gaining online account access. He discovered that passwords using the length of time between keystrokes and the length of time keys were held down could be just as accurate and potentially more secure than traditional passwords.

  17. Asthma and Air Quality, Naomi Shah:

    Taking home top prize in her age group at the Google Science Fair, Shah’s work takes a critical look at the air quality in the world today — and the impact it can have on those suffering from breathing disorders like asthma. She created a mathematical model that helps quantify the effects of air quality on symptoms. And had a few harsh words about the U.S. Clean Air Act as well, based on her findings.

  18. Mind Controlled Prosthetic Limbs, Anand Srinivasan:

    It’s hard to believe that this awe-inspiring science project came from the mind of a 14-year-old. Hooking his brain up to an EEG scanner, Srinivasan worked to test out a new method of improving mind-controlled prosthetic limbs. He found that data from the EEG could help with data classification and signal processing when using them, providing a better and more efficient user experience.

  19. Managing the Power of Household Devices, Ankush Gupta:

    You likely have a lot of vampires in your home, and not the sexy Hollywood kind either. These are energy vampires, and they’re sucking up and wasting energy that you’re still paying for. Gupta has come up with a solution with this amazing science project using demotic technology. By monitoring energy use around the home, Gupta’s system allows users to manage the power states of computers and other devices around the home to reduce energy usage and save money

    • Reducing CO2 Emissions, Jun Bing and Alec Wang:

      Using a process known as acid base neutralization, Bing and Wang developed a device capable of sequestering carbon dioxide gas released from cars (and other sources) that burn fossil fuel. Not only does it remove the harmful substance from the air, but also collects in a way so it can be stored, used, or sold.
