In the light of climate change, scientists have started to study a collection of 12000 specimens of wheat in the Natural History Museum, London, UK, that date back up to 300 years. For the most promising samples, their genomes will be sequenced. Goal is to find the varieties that are most resilient to climate change.

Hydrogen is a key gas to end our dependency on energy production generating the green house gas carbon dioxide. Now a new catalyst from inexpensive materials, copper and iron, has been found that can be used under illumination to produce hydrogen from ammonia.

In the 19th century it was assumed that the Roman emperor Sponsianus was just fictional and that coins found with his face were fakes. Now scientists find that the scratch marks on the coins prove that they were actually in circulation some 2000 years ago and that the emperor actually existed.

Tea and other foods and beverages that contain flavonoids are good for health in later life a study with more than 800 elderly women found. A particular aspect is that the largest artery in the body shows less calcification in people consuming a high level of flavonoids than that in other persons. Calcification is a predictor of risks such as heart attack, stroke, and dementia.

For 30 years Friends of Trees have planted trees along streets of Portland, Oregon, USA. A study finds now that this has lead to a significantly reduced mortality (of 20 percent for non-accidental deaths) for people living in neighbourhoods with trees planted 15-30 years before.

In diabetes type 1 the immune system attacks cells in the pancreas. In the USA, a drug, teplizumab, has been approved that can prevent this and delay the onset of type 1 diabetes by two years after a single treatment.

Studying efforts to restore prairies it has been found that although the general rule that more biodiversity is good is true, things are in general very complicated and very similar approaches can have different outcomes. For this reason it is advised to look at history to allow restoration efforts to have success.

Scientists found that leprosy bacteria have the ability to make an armadillo's liver grow to almost double its size in order to have more tissue to infect. The cells are healthy and fully functional. If understood how the bacteria do this this might open a path to regenerate liver cells.

At an archaeological site in Israel the remains of a fish were found and now dated to be around 780,000 years old, assumed to be cooked by prehistoric humans. This is much older then previous evidence for cooking some 170,000 years ago.

A vision for the future of Amazonia is described in which a different economic system is established that allows a life in harmony with nature including renewable energy systems and regenerative entrepreneurship that focuses on nature and the people living in Amazonia. This would mean a significant hope for the planets green heart.

For the first time, red blood cells that were lab grown from stem cells, have been transfused to another person. If proved safe and effective the approach opens the way to the treatment of illnesses such as sickle cell and dealing with shortages of blood donors, in particular for rare blood types.

Recursion is an important concept in learning the grammar of a language. New experiments point in the direction that crows can learn this concept as well by receiving rewards for forming well formed bracket expression such as {([])} to a depth of 3 rather than ill-formed ones such as {([)}].

In order to detect structural problems with a bridge it can be equipped with sensors that measure the vibrations when a car drives over it. Now it has been found that the same information can be collected from measurements of mobile phones that are in the cars.

In new research it is found that in some cancers a primary tumour communicates with distant site metastases and controls their growth. Once the primary tumour is removed by surgery the metastases become more dangerous and grow in an uncontrolled way. A substance has been isolated that may inhibit metastases from growing.
