A man who was diagnosed with HIV in 1988 and had to take antiviral medication for many years, has received a bone marrow transplant to treat his leukaemia. Since the donor was HIV resistant, the man is now in remission. There is hope that this may prove to be another puzzle stone in finding a cure for HIV.

A new study finds that the flavanols in cocoa reduces high blood pressure and arterial stiffness. Unlike many standard blood pressure medication, the effect is measurable only if the blood pressure is actually too high.

In a new study with more than 100,000 Americans older than 30, it was found that mortality is lowest when they exercise between 150 and 600 minutes per week (or are involved in vigorous activity between 75 and 150 minutes).

Scientists wondered whether woodpeckers have a shock absorber in order to protect their brains from the shock when they repeatedly pound their beaks against trees. New research has now found that they do not have, but that their brains can withstand the shocks without suffering a concussion.

A new study finds that ants make collective decisions - for instance, to flee rising temperatures - just as decisions are made by neural networks such as human brains or artificial neural networks.

In a study with 137 children between 6 and 10 years it was found that they uniformly prefer natural foods, such as apples, over lab-grown options with no difference as to the age of the children.

A new mattress has been developed that adjusts temperature so that people can fall asleep some 50 percent faster by cooling and heating at appropriate times. It reflects part of the 24-hour rhythm when the body temperature declines at night.

The first black hole outside the Milky Way, namely in the Large Magellanic Cloud, has been detected. It has a mass of more than nine times that of the Sun and forms a system with a star of about 25 times the mass of the Sun.

In a proof of principle experiment with mice it was found that by exchanging the blood of affected animals the build-up of Alzheimer's disease causing substances can be reduced by 40 to 70 percent. This may lead to a new therapy possibility for Alzheimer patients.

5 good climate news: 1. Wind energy production is to expand tenfold until 2035. 2. Solar energy is expanded more than expected in China so that the CO2 emission peak may be reached in 2026 instead of 2030. 3. The price of gas is so high that renewable energies are much more competitive. 4. The high energy prices are making it very attractive to become exporters of renewable energy, for instance, in form of hydrogen. 5. There are much improved technologies on the horizon to store energy.

A new study with 350000 people over 10 years finds that people who have time to exercise only on weekends are doing fine as long as they do at least 150 minutes a week of moderate intensity exercise such as brisk walks, cycling, or playing tennis. Alternatively people should do at least 75 minutes of vigorous activity like running, swimming, or playing a game of football.

A major problem in going carbon neutral is to store energy, for instance, heat from the summer to the winter. Now researchers have developed a "sand battery" that can store heat at some 500 degrees Celsius for several months.
