To our knowledge this is the first authentication study in cacao using molecular markers the researchers state.
The researchers found that the electrostatic properties of the glue that coats spider webs causes them to reach out to grab all charged particles from pollen and pollutants to flying insects.
This explains how webs are able to collect small airborne particles so efficiently and why they spring towards insects.
'Electrical attraction drags these particles to the webs so you could harvest and test webs to monitor pollution levels--for example to check for pesticides that might be harming bee populations.'
and would include any particles and chemicals that are drawn electrically to the web. We already know that spiders spin different webs
What we have found is a molecular mechanism in plants which stabilises the levels of specific proteins that restrict growth in changing environmental conditions.

they bind fatty molecules together. Fragrances are made usually of fats, also called lipids. These ambergris molecules are lipophilic-meaning they like lipids.
So they can bind the lipids in the fragrance together and make sure they stick together and to skin.

RNA molecules that kill parasites by disrupting the way their genes are expressed, Technology Review explains.
who started his career as a molecular biologist before becoming the economics minister of the Republic of Georgia and finally a biotech entrepreneur.
However, the conventional method of producing hydrogen gas relies on energy from fossil fuels to separate the atoms from other molecules like water.
Molecular Farming: HIV drug made in GM tobacco enters clinical trialstoday in London, UK regulators announced the approval of Europe's first clinical trial of an anti-HIV product produced in genetically modified tobacco plants.
Advocates of this emerging field â oe called molecular farming â oe say that protein drugs could be made more efficiently and cheaply inside GM CROPS,
The plasmids are tiny DNA molecules, separate from chromosomal DNA, and were transferred at a rate four times higher than usual thanks to the technique.

Where we mimic the cooling effect of a massive volcanic eruption by putting a lot of sulfur dioxide particles into the atmosphere to block sunlight.
The problem is that the instant those particles go away you get a redoubled warming and it has all kinds of unintended consequences.
Geraldine Thomas, Professor of Molecular Pathology at the Imperial College in London, and the scientific director of the Chernobyl Tissue bank, was asked to assess likely health effects from Fukushima after her extensive work on thyroid cancer cases in Russia.
identifying if a single molecule of explosive is present. MIT researchers created a carbon nanotube with a bee venom-based sensor,
when the bee venom peptides target molecules found in explosives. Since the proteins reacted differently,
depending on the types of molecules found in explosives, the scientists identified a finger print that is unique for each of the explosive chemicals they exposed it to,
creating other molecule types, and those derivatives could also be identified with this type of sensor.
Because molecules in the environment are constantly changing into other chemicals, we need sensor platforms that can detect the entire network and classes of chemicals, instead of just one type.
In the future, let's hope a single-molecule sensor can stop someone like Umar Farouk Abdulmutallab A k a. the underwear bomber from slipping through security.
and the cost of synthesising the molecule has fallen also. Rob Carlson, the founder of a firm called Biodesic, started tracking the price of synthesis a decade ago.
The falling cost of DNA synthesis suggests that there will be automated oeprinters for the molecule before long.
In quantum mechanics, a particle, such as an electron circling the nucleus of an atom, does not have an actual location or physical state.
All that can be said of it is a set of equations that describe its probability of being given in a place with a given energy
Two particles whose vibrations are the same in all dimensions are said to occupy the same quantum state.
Ashton Bradley and his colleagues at the Australian Research Council quantum-optics lab have shown that it possible to teleport an atom.
To demonstrate, Australian researchers made a Bose-Einstein condensate (BEC) of rubidium atoms. A BEC is a substance that occurs
it can instantly freeze certain particles it comes in contact with. The researchers then aimed a beam of rubidium atoms at the condensate.
Instantly chilled, the atoms in the beam also dropped to their lowest state, getting rid of the extra energy by giving off a burst of light.
Astonishingly, that light contains all the quantum information needed to reconstitute the atom. Aim it at another BEC,
and whatever atom it strikes takes on the quantum state of the original atom. In effect, an atom at the transmitting end has disappeared
and been reconstituted at the receiving end. There is still an atom at each end but the quantum oeidentity has moved from one to the other.
It is a long way from teleporting a few individual atoms to sending people from the Enterprise to a planet surface.
But, while it may take decades to transmit something as complicated as a virus or a single molecule of DNA,
it should be possible eventually theoretically to send a human being from one place to another through a matter transmitter.
