| Large swarms of locusts cause devastation in parts of Africa and of Pakistan by eating the crops. China plans to send 100,000 ducks to help Pakistan fight them. A single duck can eat more than 200 locusts a day and may be more effective than pesticides. |

| In general animals need oxygen to breathe, and it was the general assumption that this is the case for all animals. However, now an animal has been discovered that does not need oxygen. It is not clear yet how the animal generates energy. The animal is a small 10-celled parasite living on salmon muscle. |

| In the UK red squirrels are threatened to be replaced by non-native grey squirrels. However, a predator to both species, the pine marten, may be an ally of the red squirrel in this battle, since red squirrels can sniff out the danger better than their grey cousins. |

| Modern chemotherapy tries to hit cancer cells but avoid healthy cells. Now nanoparticles have been developed that interact preferentially with cancer cells and can this way be used for diagnostic cancer imaging. In the long run the technique may be used to transport chemical agents to the cancer cells. After a few days the nano-cells are eliminated via the kidneys. For this they must have the right size. |

| The thymus gland changes a lot through the human lifespan and plays an important role in the formation of immune T cells. Now a detailed mapping of the gland has been achieved. This may result in new cancer immunotherapies in the long run. |

| In a 23-day survey 55 blue whales were counted in the waters around South Georgia. This high number is unprecedented in the last decades and can be seen as a success of the ban of commercial whaling. |

In the Shanidar Cave in Kurdish Iraq, the skeleton of a middle- to older-aged Neanderthal has been found. It is thought that the skeleton is more than 70,000 years old. It is the first found of this kind in a decade. |

| Some plants are genetically diverse and can adapt better to different environments, in particular in the light of climate change. This is the case, for instance, for the plantain, a small plant native to Europe. |
When you smell your lover's scent then you have a better chance of sleeping well even when your partner is not present but only their used t-shirt with their scent. |

| The prevailing theory how planets formed was that many objects crashed into each other. Studying objects in the Kuiper belt now there is evidence that the creation was less violent but happened by objects clumping together. |

New research has shown that bumblebees can carry 60 to 80 percent of their own weight in nectar (that is flying, just imagine doing it walking yourself) using a second mode of flying that allows them to conserve energy. It is not yet fully understood how they do it. |

| An anti-solar cell is under development that works by sending from a warmer environment light into cold space. These so-called thermoradiative cells can produce electricity also at night - unlike standard solar cells. |

| In a recent study a class of antioxidants called flavonols have been studied in patients and it has been found that a diet rich in flavonols significantly reduces the risk of developing Alzheimer's disease. In particular the flavonol called kaempferol, which is found in kale, beans, tea, spinach, and broccoli, can half the risk. |
