The vibe was “very piratey,” Dr. Weber said. Dr. Telewski set to digging a neat, squared-off hole. But as they carved deeper and wider, there were no bottles to be found. When Dr. New organ found in world’s best-studied plant. The machinery of life is dazzlingly complex.
To try to make sense of it, researchers have spent decades focusing on so-called model organisms: creatures that are easy to study in the lab and share key features with many other forms of life. Pandemics and Traditional Plant-Based Remedies. A Historical-Botanical Review in the Era of COVID19. Introduction Pandemics have shaped the history of mankind, and plants were usually the first available therapeutic choice.
There is evidence of herbal preparations by Egyptians around 1500 BC, later improved by Greeks and Romans, and widely documented in official drug books known as Pharmacopoeias. Still in our days, traditional medicines based mostly on plants are the only therapeutic possibility for many people in developing countries (Akerele, 1993). But, also in the first world, with wide access to the most modern drugs, the use of plant-based traditional medicine is experiencing a revival, as it is seen as safer and healthier than synthetic drugs. Indeed, one advantage of traditional remedies over modern drugs is that their effects and margin of safety have been known for long. Plant Architecture and Its Evolutionary Implications. Another interesting finding borne from these models is that there doesn't seem to be strong correlations between architecture and phylogeny.
Although species within a specific genus often share similar architecture, there are plenty of exceptions. What's more, the same form can occur in unrelated species. Jepson Herbarium.

Scientists keep ignoring ugly plants. That’s a big problem. During Italy’s strict lockdown in March 2020, Martino Adamo had time to kill.
A plant researcher at the University of Turin, Adamo couldn’t go into the lab or out to the countryside for fieldwork, so he whiled away the hours with other projects. One day, he was sitting down to write the introduction to a paper on a rare plant, Tephroseris balbisiana, found in the Southwestern Alps. But he quickly realised that hardly any other scientists before him had published research about the plant. LW57 AUTUMNFINAL.
MoBot Discovered About 200 New Plants In 2020. The Missouri Botanical Garden proved crucial to plant conservation studies over the past year: All told, the organization discovered about 200 plant species, roughly 10% of what scientists identified worldwide in 2020.
Jim Miller describes it as a race against time. “We are racing against time to describe things before their habitats are destroyed or degraded. We know about 300,000 species of plants, but they are probably in excess of another 100,000 that still remain to be discovered and described,” the garden’s senior vice president of science explained on Wednesday’s St.
Louis on the Air. Miller joined the program alongside Missouri Botanical Garden President Peter Wyse Jackson to share examples of new discoveries and talk about the overarching view and particularities of this work. Tariq Stevart. How Woody Vines Do the Twist. “Whereas trees all tend to be the same shape, lianas are all over the place,” said Stefan Schnitzer, a botanist at Marquette University who was not involved in the study.
These strange stem variations give the vines an advantage. “Being asymmetrical helps you to anchor in the trees you’re growing on,” said Marcelo Rodrigo Pace, a botanist at Universidad Nacional Autónoma de México and a co-author of the study. “These lianas also have tendrils that let them grab pieces of stems and leaves and start growing.” This adaptation is “purely mechanical, architectural,” he said. The botany in Obama's official portrait represents his history. Ink Foraging in Central Park. On a recent drizzly Tuesday morning, a small group of ink enthusiasts—already rain-slicked, under umbrellas and ponchos—stood on Gapstow Bridge, in Central Park, admiring a brilliant-pink pokeweed bush.
The Park was the first stop on a five-hour foraging trip that would take them up to Hudson Heights, to collect foliage and trash, which they would cook, to make ink. Their guide, Jason Logan, the founder of the Toronto Ink Company, was in town for the launch of his book, “Make Ink: A Forager’s Guide to Natural Inkmaking.” At a reading in the West Village, he had asked the audience if anyone wanted to go foraging. Tiny Chinese seaweed is oldest green plant fossil ever found. Scientists have found in rocks from northern China what may be the oldest fossils of a green plant ever found: tiny seaweed that carpeted areas of the seafloor 1bn years ago and were part of a primordial revolution among life on Earth.
Researchers on Monday said the plant, called Proterocladus antiquus, was about the size of a rice grain and boasted numerous thin branches, thriving in shallow water while attached to the seafloor with a root-like structure. It may seem small, but Proterocladus – a form of green algae – was one of the largest organisms of its time, sharing the seas mainly with bacteria and other microbes. It engaged in photosynthesis, transforming energy from sunlight into chemical energy and producing oxygen. Earth’s biosphere depends heavily on plants for food and oxygen. The first land plants, thought to be descendents of green seaweeds, appeared about 450m years ago. Proterocladus is 200m years older than the previous earliest-known green seaweed.
Plant of the Month: Agave. The global tequila market will be worth $6.36 billion by the end of 2025. Yet 2020 marks the height of a worldwide tequila shortage that has been ramping up for more than two years, the result of unsustainable agave farming and harvesting practices. The international popularity of the liquor threatens the quantity, health, and biodiversity not only of the agave used for tequila, but all agave species and even bats.
The problem is that traditional agave farming could not keep pace with the ever-increasing global demand for tequila. As a consequence, genetically diverse, locally adapted, and traditionally cultivated agave farms were replaced by large-scale, commercial blue agave plantations, which often placed profit over crop diversity and sustainability. Produced primarily in the area surrounding the city of Tequila and in the Jalisco Highlands of central western Mexico, tequila is a spirit distilled from agave and thus a type of mescal. Which brings us to the shortage. Plant of the Month: Heliconia. Even among spectacular tropical beauties, heliconias stand out. Native mostly to Central and South America, this iconic herbaceous plant has been carried by horticulturalists and plant lovers around the world.
Heliconia’s sculptural bracts and stunning colors (reds, oranges, and yellows) have also captivated botanical artists. A painting of two heliconias in the Dumbarton Oaks Rare Book collection by the artist Margaret Mee showcases their distinctive shape and employs the opaque medium of gouache to convey their vibrant color. Mee was intimately familiar with her subject. The Prickly Meanings of the Pineapple. The pineapple, indigenous to South America and domesticated and harvested there for centuries, was a late comer to Europe. The fruit followed in its cultivation behind the tomato, corn, potato, and other New World imports. Delicious but challenging and expensive to nurture in chilly climes and irresistible to artists and travelers for its curious structure, the pineapple came to represent many things. Flowering plants may be 100 million years older than we thought.
By Ibrahim Sawal Flowering plants may have evolved 250 million years ago, more than 100 million years earlier than the oldest fossilised flowers so far found. Today, flowering plants – known as angiosperms – are the most diverse group of land plants. The oldest angiosperm fossils so far found are 135 million years old, and many researchers believe this is when the group originated. The fossil record suggests the group then became diverse by 130 million years ago. But how flowering plants became highly diverse so shortly after their emergence has long perplexed researchers, including Charles Darwin. Top 10 species new to science in 2020.

University of Oxford Botanic Garden and Arboretum. The pungency of chillies is due to a specialized metabolite, capsaicin, concentrated in tissues that surround the seeds inside the fruits. Capsaicin content is subjectively measured using Scoville heat units (SHU), i.e., how much a chilli extract must be diluted before its ‘heat’ is undetectable. It’s Called ‘Plant-Based,’ Look It Up. The terms “vegan” and “plant-based” are often used interchangeably, but there’s a growing effort to define just what it means to follow a plant-based lifestyle.
