Animals are key to restoring the world's forests
Animals are key to restoring the world’s forests
By dispersing seeds, animals can rapidly reestablish plant diversity in degraded forests As UN climate talks close in Egypt and biodiversity talks begin in Montreal, attention is on forest restoration as a solution to the twin evils roiling our planet. Forests soak up atmospheric carbon dioxide and simultaneously create habitat for organisms.

New function of the CRISPR gene scissors discovered
New function of the CRISPR gene scissors discovered
Protein scissors activate defense function, a study shows For several years now, the CRISPR/Cas9 gene scissors have been causing a sensation in science and medicine. This new tool of molecular biology has its origins in an ancient bacterial immune system. It protects bacteria from attack by so-called phages, i. e.

Vegetation-free patches encourage ground-nesting wild bees
Vegetation-free patches encourage ground-nesting wild bees
Göttingen researchers investigate ways to improve conservation management of wild bees on calcareous grasslands Relatively little is known about the nesting requirements of ground-nesting wild bees, although nesting sites are of central importance for most wild bee species. There are almost 600 wild bee species in Germany and 75 per cent nest in the soil.

Protein Spheres Protect the Genome of Cancer Cells
Protein Spheres Protect the Genome of Cancer Cells
Hollow spheres made of MYC proteins open new doors in cancer research. Würzburg scientists have discovered them and report about this breakthrough in the journal "Nature". MYC genes and their proteins play a central role in the emergence and development of almost all cancers. They drive the uncontrolled growth and altered metabolism of tumour cells.

Unexpected cognitive deteriorations in epilepsy
Unexpected cognitive deteriorations in epilepsy
Study by the University of Bonn: Surgical tissue indicates rare secondary disease In severe epilepsies, surgical intervention is often the only remedy - usually with great success. While neuropsychological performance can recover in the long term after successful surgery, on rare occasions, unexpected declines in cognitive performance occur.

Zombie viruses on a hijacking trip
Zombie viruses on a hijacking trip
Ancient dormant sequences in the genome impact embryonic development in unexpected ways The mammalian genome contains retroviral sequences that are in an undead but mostly "harmless" state. An international research team recently discovered how some of these retroviral gene fragments affect embryonic cells if they are unleashed.

Poor diet harms blood vessels
Poor diet harms blood vessels
Over the last few decades, the number of obesity sufferers has continued to increase and is now one of the leading causes of death worldwide - 650 million adults are classified as obese. The World Health Organization (WHO) defines obesity as the accumulation of excess fat in the body, which poses risks to healthy living.

Genes and tongues are not always tied together
Genes and tongues are not always tied together
A global database helps explore the complex history of our genes and languages Does the history of our languages match the history of our genes? Charles Darwin thought yes, others said no. An interdisciplinary team of researchers from the Max Planck Institute for Evolutionary Anthropology, the University of Zurich and Harvard University has put together GeLaTo, a global database linking linguistic and genetic data.

Hominins were cooking fish already in the early Paleolithic period about 780,000 years ago
Hominins were cooking fish already in the early Paleolithic period about 780,000 years ago
Ancient fish teeth discovered at the archaeological site of Gesher Benot Ya'aqov in Israel provide earliest evidence of our prehistoric ancestors deliberately cooking foodstuff Nutrition and the ability to prepare foodstuffs helped facilitate the evolution of the human species. Considered particularly relevant to the development of the genus Homo in this context are the processes of cooking.

New target for Alzheimer's therapies found
New target for Alzheimer’s therapies found
The protein medin is deposited in the blood vessels of the brains of Alzheimer's patients along with the protein amyloid-β. DZNE Re-searchers have discovered this so-called co-aggregation. They have now published their observation in the renowned journal Na-ture. "Medin has been known for over 20 years, but its influence on diseases was previously underestimated.

Tumors: forecasting the risks of brain surgery
Accurately predicting possible post-surgical effects on speech Can surgeons quantify the risk of aphasia when removing a brain tumor? To find out, researchers at Klinikum rechts der Isar of the Technical University of Munich (TUM) are analyzing the brain as a network. In a current study with 60 patients, they already achieved an accuracy rate with three quarters of their predictions.

Gene plays important role in embryonic development
Study at the University of Bonn identifies gene that can cause malformations if altered An international study led by the medical Faculty of the University of Bonn has identified a gene that plays an important role in the development of the human embryo. If it is altered, malformations of various organ systems can result.

Molecular monitoring of RNA regulation
Molecular monitoring of RNA regulation
New biological tool for tracking cellular processes The better we understand cellular processes such as RNA regulation, the better molecular therapies can be developed. Until now, it has been especially difficult to track the regulation of non-coding RNA, which is RNA that is not further converted into proteins.

Synthetic peptides may suppress formation of harmful deposits
Synthetic peptides may suppress formation of harmful deposits
Alzheimer's disease and type 2 diabetes In Alzheimer's disease, the degeneration of brain cells is linked to formation of toxic protein aggregates and deposits known as amyloid plaques. Similar processes play an important role also in type 2 diabetes. A research team under the lead of the Technical University of Munich has now developed "mini-proteins", so-called peptides, which are able to bind the proteins that form amyloids and prevent their aggregation into cytotoxic amyloids.

Inspired by nature: Making bacteria ’mute’
Nanoparticles of cerium dioxide intervene like natural enzymes in biological processes and alter signal molecules / Formation of biofilms is prevented Bacteria love moist surfaces. Once they have settled there, they do not live as solitary organisms but form larger communities that are surrounded by a protective film.

Lasting reciprocity promotes cooperation
Lasting reciprocity promotes cooperation
The behavioral strategy allows for mistakes and thus promotes cooperation Understanding mutual cooperation is a key element in understanding how people work together. Whether it is friends doing favors for each other, animals exchanging food or aid, or nations coordinating policies, these are all essentially cooperative interactions.
