No, that is a New Zealand pohutukawa (Metrosideros excels) and it blooms for Christmas, not Easter.
This flower is the flower of the Metrosideros excelsa, the tree is also called pōhutukawa tree and New Zealand Christmas tree.
According to its wikipedia page the tree:
The tree flowers from November to January with a peak in mid to late December (the Southern Hemisphere summer), with brilliant crimson flowers covering the tree, hence the nickname ...
No, Aloe Vera doesn't help prevent or heal sunburn.
I have to admit to being surprised by this. I was expecting to see a (small) effect.

To repeat Oddthinking's answer, that is a simple NO. The mustard seed is far from the smallest. That distinction belongs to the Orchid. With over 26,000 species, many having seeds no larger than grains of dust from 0.4mm to 0.2mm in size. This document (PDF) actually gives a pretty full accounting of Orchid seeds.
According to the US Department of Agriculture, Forest Service publication THE EFFECTS OF URBAN TREES ON AIR QUALITY
Trees remove gaseous air pollution primarily by uptake via leaf stomata,
though some gases are removed by the plant surface. Once inside the leaf, gases diffuse into intercellular
spaces and may be absorbed by water films to form acids ...
Several sources put mustard seeds as between 1 and 2 or 3 mm in diameter.
During the hulling of white mustard seeds and rapeseeds,
1.4 mm to 2.8 mm in diameter, on a disk equipped with blades [...]
Meanwhile, begonia seeds, as an example, are much smaller:
Species description Begonia fangii [...] Seeds many, brown, ellipsoid, 0.5-...
There are two pathways in photosynthesis.
Light reactions where O2 is released by splitting H2O.
Dark reaction (Calvin Cycle) where CO2 is used to make sugars
The energy to drive these reactions come from sunlight. CO2 is absorbed via stomata, and O2 is released by the same stomata.
In CAM photosynthesis, or Crassulacean-Acid metabolism, the plant ...
The Dracaena cinnabari (Socotra dragon tree or dragon blood tree) is well known for having a distinct red sap or resin and there are a number of other plants that also exhibit similar "Dragons's Blood". As noted in the Wikipedia article on Dragon's Blood:
The dragon's blood known to the ancient Romans was mostly collected
from D. cinnabari, and is ...
Gympie-Gympie is said to have the most painful sting of any plant in Australia with reference to this source.
Can the pain last for years?
Answer: Partly yes up to one year referring to research by Marina Hurley in 2000. The stinging sensation can be felt up to a year since human bodies cannot break down silicon.
The hairs are often so small that the ...
Chlorine does evaporate, so if exposed to air (e.g. in a bucket) in warm water (especially under UV light or sunlight) it will probably mostly dissipate overnight.
Both fluoride and chloramine will not similarly dissipate, if you want them removed you need to filter them out (e.g. with activated carbon) or distill the water.
Can You Remove Fluoride ...
The UN Food and Agricultural Organisation (FAO)'s forest report State of the World’s Forests states that forests cover 4 billion hectares of the Earth's surface:
Forests currently cover about 4 billion hectares, about 31 percent of
the earth’s land surface (FAO, 2010b).
It also provides a graph of human deforestation over the past 200 years:
As can be ...
Not impossible, but highly unlikely
The technology described does exist. Scientifically this is called Plant Microbial Fuel Cell. However Bioo's claims of 40 W/m² seem greatly exaggerated.
People involved in e-Plant, a Dutch company which already has similar product on the market have published a number of scientific papers in Biotechnology for Biofuels ...
Cleve Backster's work was unreproducible by himself or others, and has been discarded as a working hypothesis.

Vi Hart (Wikipedia biography) has produce a three part series of videos describing this phenomenon, called Doodling in Math: Spirals, Fibonacci, and Being a Plant.
It explores the nature of spirals, Fibonacci and the patterns seen in plants.
The third part in the series describe how this phenomena can be explained with a simple model of growth hormone.
As mentioned in the comments, the fact that The Times published this story, with a photograph of said plant, is already compelling evidence that it happened, but of course it's possible they have been fooled. If we're not willing to take The Times nor Mr. Latimer's word as evidence, we really have no way to prove that he's telling the truth, as we haven't ...
The show 'Monster Inside Me' actually has documentation of an older man with respitory problems who did asperate a raw pea and it did germinate and start to grow inside his lung. It was removed on the 3rd Bronchisotomy trying to get a biopsy. All germination requires is moisture, warmth and oxygen. Any seed could do this, although it would not get very ...
This is a well known urban legend.
This letter published on Chest Journal addresses the issue
Trees Don't Grow in the Lungs! - Chua and Mehta, 2009
We would like to bring to the attention of readers that trees do not grow in humans. To the best of our knowledge, there has never been a single report in the medical literature of seeds and/or plants ...
There was a joint Hungarian-German study on the subject led by Dr. Gábor Horváth at Eötvös University in Budapest, Hungary.
A team of physicists, troubled by the lack of scientific evidence for the phenomenon, set out to test the theory that water droplets on leaves can act like mini magnifying lenses, focusing the sun's rays and leaving a leaf's surface ...
In this paper from 2006, it states
In the present study, the existence of negative and positive feedback
regulation of ethylene biosynthesis is demonstrated in banana pulp and
peel tissues, respectively.
So, ethylene synthesis occurs in both the fruit and peel, and if there is any in the stem, it's likely irrelevant since the majority of the ...
No, but one should not expect a literal interpretation of of parable.
It is a good idea to use an interlinerar bible when reading translated works. A concordance or other search tool that allows you to search in multiple languages can also be useful to determine the best translation. In this particular instance, the translation you quoted above seems fairly ...
The Wikipedia page has since been rephrased to contain the following, more accurate, paragraph:
The maize plant is often 3 m (10 ft) in height, though some natural strains can grow 13 m (43 ft). The stem is commonly composed of 20 internodes of 18 cm (7.1 in) length. A leaf, which grows from each node, is generally 9 cm (4 in) in width and 120 cm (4 ft) ...

Fibonacci Numbers and Nature
Look at the 'Leaf arrangements' sections . You can clearly see that the leave arrangements and the turn of leaves both follow Fibonacci sequence and also note the section 'Always Fibonacci? ' You will find that Nature is too unpredictable to always follow Fibonacci number.
How good is the evidence presented in the thesis?
The thesis does not draw upon molecular phylogeny evidence. Like DNA evidence in court, DNA phylogeny is considered to be much more compelling evidence than 1000 year old witness accounts. Most scientific studies to determine when speciation occured is nowdays done by molecular analysis rather than ...
This meta-analysis read 147 original scientific papers about GMO crops. On average those papers found a 22% increase in crop yields and a 37% decrease in pesticide use for GMO vs non-GMO crops.
The meta analysis has been quite highly cited and the citing papers I looked at, (1 2), repeat the conclusions of the meta-analysis uncritically. The meta-...
Caffeine on insects
That "caffeine kills insects" is an old myth:
"I find it considerably interesting and even amusing," said Bussey Professor of Biology Carroll M. Williams. "Caffeine may be an insecticide, but it is not a very powerful agent."
The study also determined that caffeine combined with other insecticides increases their killing power. ...
Artificial banana flavor was derived from natural banana flavor; bananas, both Gros Michel and Cavendish, as well as other varieties including "wild" bananas, contain isoamyl acetate, amyl acetate and related compounds which result in their smell and taste.
The synthesis of isoamyl acetate from other sources (namely the reaction of isopentanol aka amyl ...
In coniferous regions, it is possible for conifers to be a major source of particulate emissions. A good study is Characterization of a large biogenic secondary organic aerosol event from eastern Canadian forests Atmos. Chem. Phys., 10, 2825–2845, (2010).
Here we present evidence for the formation of the most

From Involvement of receptor potentials and action potentials in mechano-perception in plants Australian Journal of Plant Physiology (2001) volume 28, page 567-576:
Plants are always exposed to various external stimuli, such
as light, gravity, chemicals, temperature and mechanical
stress. The sensitivity of plants to these stimuli is as high as
No. Not directly and not without serious doubts. There were botanical misidentifications in taxonomy of the plant and for the aetiology of the consequences of a sting as well.
The worst urticaria species known contains chemicals that may well kill a human, but while indeed extremely painful the mode of delivery and concentrations make that not very ...
