Chemists give chance a helping hand
Chemists give chance a helping hand
Whether they are synthetic materials such as PET and Teflon, medicines or flavourings, life without synthetically produced compounds is barely conceivable in our everyday lives today. The chemical industry depends on efficient, long-term methods of producing synthetically derived molecules. For this purpose, chemists often use catalysts, i.e. additives with which they can facilitate and control chemical reactions.

Scientists alarmed by bark beetle boom
Scientists alarmed by bark beetle boom
Bark beetles are currently responsible for killing an unprecedented number of trees in forests across Europe and North America. Researchers are therefore urging to step up research into bark beetles - also in view of climate change. "Bark beetles lay waste to forests" - "Climate change sends beetles into overdrive" - "Bark beetles: can the spruce be saved?": These newspaper headlines of the past weeks covered the explosive growth of bark beetle populations and its devastating impact on timberlands.

It is becoming much more common for patients to be treated with several different medications. It is often necessary for the patient to take them at fixed intervals - a limitation that makes everyday life difficult and increases the risk of doses being skipped or forgotten.

Millions of war survivors worldwide suffer from mental illness
Psychologists at Münster University estimate the prevalence of post-traumatic stress disorder and depression after wars in the total population Wars leave their marks on people - the physical damage is usually obvious, but the scars a war can leave in the psychological well-being of survivors often remain beneath the surface.

Spinach Extract Improves Athletic Performance
Freie Universität Berlin Contributes to Research Project Backed by the World Anti-Doping Agency No 193/2019 from Jun 25, 2019 According to a study conducted by a group of international researchers, including experts from Freie Universität Berlin, a chemical extract from spinach plants can be used to boost the performance of competitive athletes.

(Not only) the wind shows the way
(Not only) the wind shows the way
06/24/2019 When the South African dung beetle rolls its dung ball through the savannah, it must know the way as precisely as possible. Scientists have now discovered that it does not orient itself solely on the position of the sun. The South African dung beetle Scarabaeus lamarcki has - to put it mildly - an interesting technique to ensure its offspring a good start in life.

Cell Division at High Speed
Cell Division at High Speed
06/19/2019 When two proteins work together, this worsens the prognosis for lung cancer patients: their chances of survival are particularly poor in this case. In malignant tumours, the cells usually proliferate quickly and uncontrollably. A research team from the Biocenter of Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, has discovered that two important regulators of cell division can interact in this process.

Tox
Tox "exhausts" immune cells
Normally, the immune system goes into a state of maximum alert following a viral infection. It triggers the activation of a variety of immune cells such as T and B cells. These procreate in large numbers, and aggressively combat the infected cells. However, if the immune system does not manage to defeat the virus, then immune cells appear with highly inhibited functions.

Spotting fake videos with artificial intelligence
Spotting fake videos with artificial intelligence
Last year a video clip featuring Barack Obama created quite a stir. It seemed to show the ex-president calling his successor Donald Trump "a total and complete dipshit". Ultimately, the people behind the clip admitted that it was no more than a highly convincing fake. It is now possible to perform this kind of trickery even in real time.

Exciting Plant Vacuoles
Exciting Plant Vacuoles
06/14/2019 Researchers have filled two knowledge gaps: The vacuoles of plant cells can be excited and the TPC1 ion channel is involved in this process. The function of this channel, which is also found in humans, has been a mystery so far. Many plant processes are not different from humans: Cells and tissues in grain plants, including maize also communicate through electrical signals.

Why does dandelion never fall ill?
Why does dandelion never fall ill?
Researchers at Münster University find out that dandelion possesses enzymes that have untypical abilities for plants / Study in "Angewandte Chemie' Plants possess enzymes called polyphenoloxidases, which can oxidize certain chemical compounds and thus produce the typical brown colour that we know, for example, from freshly cut apples.

Immortal quantum particles
Immortal quantum particles
As the saying goes, nothing lasts forever. The laws of physics confirm this: on our planet, all processes increase entropy, thus molecular disorder. For example, a broken glass would never put itself back together again. Theoretical physicists at the Technical University of Munich (TUM) and the Max Planck Institute for the Physics of Complex Systems have discovered that things which seem inconceivable in the everyday world are possible on a microscopic level.

Bitcoin causing CO2 emissions comparable to Hamburg
Although Bitcoin is a virtual currency, the energy consumption associated with its use is very real. For a Bitcoin transfer to be executed and validated, a mathematical puzzle must be solved by an arbitrary computer in the global Bitcoin network. The network, which anyone can join, rewards the puzzle solvers in Bitcoin.

Reducing soft drink consumption effectively
The negative effects of sugary drinks have prompted the World Health Organization (WHO) to call on politicians, business leaders and society as a whole to design and implement effective ways to wean consumers off their predilection for soft drinks and to support healthier beverage choices. But what measures are most likely to reduce soft-drink consumption? In collaboration with the Cochrane Network, researchers based at TUM and LMU set out to answer this question.

"Interdisciplinary research takes time"
It seems that new scientific institutions and research projects are all about "interdisciplinarity". Is it all hype? It is not all hype, not at all. We are increasingly encountering issues that cannot be resolved using the methods of any one discipline. As a matter of fact, interdisciplinarity was already enabling major leaps forward even before it was intentionally promoted: After the Second World War, several physicists transferred to biology in the wake of the atomic bomb shock.

Checkmate for hepatitis B viruses in the liver
Infections with HBV are a global health problem. According to the World Health Organisation (WHO), more than 260 million people worldwide are chronically infected with the virus. Vaccination prevents new HBV infections, but for people who are chronic carriers of the virus, a cure has not yet been found.

Dwarf planet Ceres: a new form of volcanism found
An international research team solves the mystery of how the mountain Ahuna Mons on Ceres was probably formed / Study in "Nature Geoscience" The scientists could hardly believe their eyes when they first saw this formation on the images acquired by their Framing Camera on board the Dawn space probe: a symmetrical mountain over 4000 metres tall and with steep, smooth sides rising over the crater-strewn surface of.

Do Video Games Drive Obesity?
Are children, teenagers and adults who spend a lot of time playing video games really more obese? A meta study conducted with the University of Würzburg has looked into this question. The cliché is true - but only for adults. A chubby teen lolling on the sofa for hours on end, the game controller in one hand, a bag of crisps at his side and a bottle of coke on the coffee table.

Magnetism discovered in the Earth’s mantle: New findings on the Earth’s magnetic field
New findings on the Earth's magnetic field: researchers show that the iron oxide hematite remains magnetic deep within the Earth's mantle / Study published in "Nature" journal The huge magnetic field which surrounds the Earth, protecting it from radiation and charged particles from space - and which many animals even use for orientation purposes - is changing constantly, which is why geoscientists keep it constantly under surveillance.
