The conservation effort to save sea turtles seems to pay off and in general the number of the different species are all increasing. It is an example that conservation efforts can work.

Artificial photosynthesis has been improved to the point that it is more efficient than natural photosynthesis. This offers a route to carbon neutral fuels.

When blood is sent to a lab for analysis the result may take days. A new blood testing approach is under development which allows to make some tests based on sound waves. The results could be available within 10 minutes.

In a study a roadmap has been worked out how in 139 countries (among them the biggest CO₂ polluters) the energy supply can be transformed to 100 percent renewable energy production (that is, energy from wind, water, and solar). This will also create 24 million long-term jobs.

Writers probably knew it all along, but now there is psychological evidence. Expressive writing about a stressful task can reduce the actual stress in the upcoming task and people worry less about their performance.

The introduction of zero plays an important role in the history of mathematics. In a 1800 year old Indian text now the probably oldest known written zero has been detected. This means that zero has been in use for 500 years more than previously thought.

Squirrels use sophisticated strategies to hide nuts so that they can find them again but that they are still hidden from other squirrels. They also distinguish between different quality ranges for their nuts.

Some exemplars of a giant tortoise, chelonoidis nigra abingdonii, thought to be extinct since 2012, have been found on some Galapagos island. There is now another chance for their survival.

Listening to happy music seems to stimulate creativity. In psychological experiments 155 participants were split in groups listening to happy, calm, sad, or anxious music, or to silence. Those listening to happy music performed best in certain tasks and came up with the most creative solutions.

A tiny power generator has been built which is able to generate electricity from the flow of blood in blood vessels.

Scientists have succeeded to transform standard human skin cells into motor neurons without having to go through a stem cell state. This may lead to a treatment of motor neuron related illnesses such as spinal muscular atrophy.

Scientists managed to extend the lifespan of fruitflies by taking out damaged mitochondria (power cells) in middle aged fruitflies. Potentially this could be transfered to humans and the onset of age-related illnesses such as Altzheimer's disease could be delayed.

Bacteria are often viewed as isolated beings. However, as has been found out they live often in colonies and can even communicated with each other using electrical signal based on potassium ions not unlike the communication between neurons in a human brain. The findings may lead in the long run to new ways of treating bacterial infections.

A new cooling system is under development which works by sending heat of liquids by radiation into space. This is more energy efficient than traditional cooling with electricity.

When operating a surgeon wants to remove all of the cancerous cells but as few of the healthy ones as possible. A new pen which makes use of a mass spectrometer can determine with an accuracy of 96% whether cells are cancerous or not in 10 seconds.

The zika virus has been found effective against aggressive tumours in mice. The virus that causes bad brain damage in babies may offer a new treatment against hard-to-treat brain cancer in adults.

In brains affected by Alzheimer's disease, abnormal tau proteins lead to an influx of calcium in the neurons, which then does serious damage also by making more tau proteins abnormal. There is now some understanding why this cascade of bad events can be stopped by HDAC6 inhibitors. This understanding may lead to an effective medication against Alzheimer's disease.

Wind energy is not only clean but also cheap. It can currently be produced at 2 US cents per kilowatt-hour and prices are still falling.

A 1800 kg bomb of World War II, which was found earlier the week, has successfully been defused in Frankfurt, Germany. More than 60,000 people had to leave their homes during the defusion, since if it had gone wrong, the explosion would have been very big and destroyed many houses.

Bats are known for using echolocation. However, as has been studied now humans are also able to learn echolocation by making clicking sounds with the mouth and listening to the reflected sound waves.

A new X-ray laser which is in a more than 3km long tunnel and cost around one billion Euros has been taken into operation in Hamburg, Germany. It will be able to take pictures with a very high precision of tiny objects such as proteins.
