In the past biomaterials were developed that can be injected in the heart to start a healing process after a heart attack. Now a new type of biomaterial has been tested in animals that is transported to the damaged tissue (heart or brain, e.g.) by the blood.

Coffee with milk seems to have an anti-inflammatory effect, since it contains a combination of proteins and antioxidants that supplement each other to stimulate immune cells, a new study finds.

Perovskite solar cells are low-cost but very sensitive to temperature changes. Now solar cells based on perovskite enhanced by a polymer have been produced that can tolerate big temperature fluctuations.

In a new study with older women it was found that walking or other physical activity for half an hour per day reduces the risk of mild cognitive decline and dementia (by about a fifth to a third).

In a new study, more than 5000 untrained participants were shown ten of the most common gestures (of some 80 known in total) used by apes in twenty videos. They could understand them in more than half of the cases, way more than could be expected by chance.

With increasing amounts of the greenhouse gas CO2 in the atmosphere, capturing it becomes more important. Now a relatively cheap approach for carbon capture has been suggested, namely, to first convert the CO2 to methanol, which can then be the starting point for the conversion to other materials.

Dietary nitrate as found in beetroot juice can significantly increase the muscle force while exercising, a new study finds. It is assumed that the nitrate serves as a source of nitric oxide.

When medication is applied to the brain, e.g., potential Alzheimer gene therapy, then there is the problem that the brain's protection mechanism, the so-called blood-brain barrier, prevents the medication from reaching the brain's cells. Now a nano-particle based approach has been found that can overcome this barrier.

In a new five year study, time restricted eating could not be proved to be associated with weight loss; however, a small number of daily meals could be, as well as the reduction of the overall calorie intake.

An estimate says that in the USA in 2018, 47 kg of textiles were thrown away per person on average and only a small amount (13 percent globally) is recycled. There are new approaches to increase this, for instance, by enzymes that can degrade PET (polyethylene terephthalate) molecules.

In a new study it has been found that people who are exposed three to four times per week to green and/or blue spaces in urban environments less frequently take psychotropic, antihypertensive and asthma medication.

For the first time scientists managed to detour lightning by a high frequency laser. It is assumed that the intense laser pulses heat up the air forming a canal that has a higher conductivity thereby diverting the bolt. In the long run the approach may be used to protect infrastructure such as an airport.

Too much sitting is a problem for many people, even those who exercise regularly. A new study finds that a five minute exercise "snack" every half hour of sitting can offset its harmful effects.

People who feel guilty typically want to take remedial action such as apologizing. Their situation can also be improved by giving them a placebo pill. This is effective whether they are told that it is a real medication or openly told that it is a placebo.

The international Montreal agreement of 1987 to stop using CFCs (chlorofluorocarbons) is working and the ozone layer is recovering so that it should be fully restored over the Antarctic by 2066 and some 20 years earlier elsewhere (assumed the protection is maintained).

Many modern concrete buildings crumble, but Ancient Roman concrete buildings keep strong after millenia. Now there is an indication why this is so. The Roman concrete contains tiny lime clasts that seem to provide it with the capability to refill cracks before they spread.

A new study finds that adults who keep themselves well hydrated are healthier and live longer. They have fewer chronic conditions such as heart problems. A good level of fluid intake depends on different factors, one suggestion is that women should take in 1.5 to 2.2 litres daily and men 2 to 3 litres.

A new study comes to the conclusion that policy makers should understand that elephants need protection since they are of very great importance which goes far beyond their mere economical value. They are not only important in themselves, but also play important roles in the socio-ecological systems in which they live.
