It has been known for some time now that plants are able to communicate among themselves although vast majority of inter-plant communication still eludes us. Researchers from Wageningen University tried to decipher some of the mystery
The question of how life on Earth first emerged is one that humans have been asking themselves since time immemorial. While scientists are relatively confident about when it happened, there has been no definitive answer as to why it did. How did amino acids, the chemical building blocks of life, come together roughly four billion years ago to create the first protein molecules?
You might not really be sure you saw what you think you saw when the first one shows up. But you stare in the direction of the flicker of light and there it is again – the first firefly of the evening. If you are in good firefly habitat, soon there are dozens, or even hundreds, of the insects flying about, flashing their mysterious signals.
Many of us will have experienced that super friendly cat who seems to love being stroked one minute, only to bite or swipe at us the next. It might be easy at this point to blame it on the cat, but what’s likely happening here is that we’re just not stroking them right.
A nighttime arrival at Amsterdam’s Schiphol Airport flies you over the bright pink glow of vegetable production greenhouses. Growing crops under artificial light is gaining momentum, particularly in regions where produce prices can be high during seasons when sunlight is sparse.
The question of how life first emerged here on Earth is a mystery that continues to elude scientists. Despite everything that scientists have learned from the fossil record and geological history, it is still not known how organic life emerged from inorganic elements (a process known as abiogenesis) billions of years ago.
Chernobyl has become a byword for catastrophe. The 1986 nuclear disaster, recently brought back into the public eye by the hugely popular TV show of the same name, caused thousands of cancers, turned a once populous area into a ghost city, and resulted in the setting up of an exclusion zone 2600km² in size.
Coral reefs are home to so many species that they often are called “the rainforests of the seas.” Today they face a daunting range of threats, including ocean warming and acidification, overfishing and pollution. Worldwide, more than one-third of all coral species are at risk of extinction.
Have you have seen ants this year? In Britain, they were probably black garden ants, known as Lasius niger – Europe’s most common ant. One of somewhere between 12,000 and 20,000 species, they are the scourge of gardeners – but also fascinating.
The teasing temptation of a sugary treat can often get the better of us. But don’t worry, we’re not the only ones. The saccharine substance that our sweet tooth finds so hard to resist is also powerfully seductive to mosquitoes. And according to new research, in helping to keep the pests away from our blood-rich body parts, sugar may for once be good for our health.
Because of their delicate organic and decomposing nature, fossilize fungi are extremely rare. So rare, in fact, that a new discovery has just pushed back the earliest evidence of fungi by at least 500 million years – doubling their age.
The news is grim: According to a report compiled by hundreds of scientists from 50 countries, Earth is losing species faster than at any other time in human history. Thanks to climate change, coastal development and the impacts of activities such as logging, farming and fishing, roughly 1 million plants and animals are facing extinction.
The parasitic wasp can do something special. The insect is able to puncture rotten wood or a fruit and thus lay eggs in larvae that live in these kinds of places. The wasp uses a long tube for this. But this tube is so long that the animal cannot push it into the material itself. The secret is that this "needle", which consists of three separate parts, can pull itself forward.
Insects scuttle, chew and fly through the world around us. Humans rely on them to pollinate plants, prey on insects that we don’t get along with, and to be movers and shakers for Earth’s ecosystems. It’s hard to imagine a world without insects.
Panama disease, an infection that ravages banana plants, has been sweeping across Asia, Australia, the Middle East and Africa. The impact has been devastating. In the Philippines alone, losses have totalled US$400m. And the disease threatens not only the livelihoods of everyone in this US$44 billion industry but also the 400m people in developing countries who depend on bananas for a substantial proportion of their calorie intake.
Billions of migratory birds pass through the night sky each spring and fall. Birds use stars to orient their journey between summer breeding grounds and winter feeding grounds. The artificial lights produced by humans disrupt the migration of birds, often with fatal consequences.
