Mob mentality rules jackdaw flocks
Jackdaws are more likely to join a mob to drive off predators if lots of their fellow birds are up for the fight, new research shows.

Earthquake in the cell
Nuclear abnormalities such as nuclear blebs and micronuclei have devastating consequences for the genetic material and are associated with cancer or ageing. Scientists now revealed that the epigenetic enzyme MOF is crucial for the morphological integrity of the mammalian nucleus. Moreover, the study characterized the epigenetic landscape of nuclear abnormalities and discovered a formerly unknown epigenetic mechanism that seems to protect cells from additional damage.
Read moreGene responsible for lutein esterification in bread wheat identified
Researchers have identified and confirmed the gene responsible for lutein esterification in bread wheat. The activity of this gene controls the timing of esterification in grain, which is related to storage and nutritional qualities of bread wheat and other grains.

Engineers have shown that the length of collagen fibers has a roll to play in the ability of normal cells to become invasive.

For the first time ever, a professor has observed a crystallized iron product called hemozoin being made in mammals, with widespread implications for future research and treatment of blood disorders. Findings could be used to treat sickle cell disease and malaria patients, while opening up diverse research avenues across immunology, parasitology, neuroscience, microbiology, and even urology.
Read moreSquid-inspired robots might have environmental, propulsion applications
Inspired by cephalopods, scientists developed an aquatic robot that mimics their form of propulsion. These high-speed, squidlike robots are made of smart materials, which make them hard to detect, while maintaining a low environmental footprint. Physicists used numerical simulations to illustrate the physical mechanisms and fluid mechanics of a squid's swimming method. By using this form of locomotion, the new device can achieve impressive speeds, just like its animal inspiration.

Scientists have gained a new understanding of how tiny, ultra-resilient invertebrates known as tardigrades, or 'water bears,' are protected in extreme conditions. Tardigrades are found in water environments around the world — including mountainous, deep sea and Antarctic environments. The researchers discovered that a tardigrade protein named Dsup binds to chromatin — DNA inside cells — and forms a protective cloud against extreme survival threats such as radiation damage.

Jellyfish are animals that possess the unique ability to regenerate body parts. A team of scientists has now revealed the cellular mechanisms that give jellyfish these remarkable 'superpowers.'

Negative perception of a regulatory authority diminishes the honesty of those regulated. This is the conclusion of an experiment with EU-skeptic commercial fishermen and Brexit voters. The findings can help to assess the effectiveness of unmonitored EU fisheries regulations.
Read moreA closer look at monogamy and polygamy in brood parasitic birds
Researchers have discovered that cowbirds conform to Bateman's Principle, despite investing no energy into parental care. Surprisingly, 75% of the cowbirds in the system were monogamous. Future research will expand upon these findings and broaden the understanding of how cowbirds might select the nests they parasitize, what role the males could play to assist the females, and why monogamy could be such a benefit.
