Maternal instincts lead to social life of bees Posted: 26 Feb 2021 09:12 AM PST The maternal care of offspring is one of the behavioral drivers that has led some bee species to have an ever-expanding social life over the history of evolution, new research has found. By virtue of being in a social group the genome itself may respond by selecting more social, rather than non-social genes. The behavior and social environment come first setting the stage for future molecular evolution.

Largest cluster of galaxies known in the early universe Posted: 26 Feb 2021 07:38 AM PST A study has found the most densely populated galaxy cluster in formation in the primitive universe. The researchers predict that this structure, which is at a distance of 12.5 billion light years from us, will have evolved into a cluster similar to that of Virgo, a neighbor of the Local Group of galaxies to which the Milky Way belongs.

Targeted spraying to prevent malaria in low-transmission setting halves cost of current practice Posted: 26 Feb 2021 07:38 AM PST Furthermore, the targeted Indoor Residual Spraying (IRS) intervention was safe, less costly, and more cost-effective compared with standard 'blanket' IRS, meaning savings could potentially be reallocated to other malaria control and elimination activities.

Dinosaur species: 'Everyone's unique' Posted: 26 Feb 2021 07:38 AM PST 'Everyone's unique' is a popular maxim. All people are equal, but there are of course individual differences. This was no different with dinosaurs. A study has now revealed that the variability of Plateosaurus trossingensis was much greater than previously assumed. The paleontologists examined a total of 14 complete skulls of this species, eight of which they described for the first time.

How photoblueing disturbs microscopy Posted: 26 Feb 2021 07:38 AM PST An undesirable effect can occur in super-resolution fluorescence microscopy: photoblueing. A new article shows how it can be prevented or made useful for research.

Can a robot operate effectively underwater? Posted: 26 Feb 2021 07:38 AM PST Researchers find sea stars' shape plays an important role in their ability to withstand dynamic water forces and remain attached to surfaces. Understanding such shape shifting could help design underwater robots that can similarly adapt to extreme hydrodynamic environments.

Early-warning for seizures could be a game-changer for epilepsy patients Posted: 26 Feb 2021 07:38 AM PST A research team has developed mathematical model to predict seizures that will give epilepsy patients an accurate warning five minutes to one hour before they are likely to experience a seizure.

Social media use driven by search for reward, akin to animals seeking food Posted: 26 Feb 2021 07:38 AM PST Our use of social media, specifically our efforts to maximize 'likes,' follows a pattern of 'reward learning,' concludes a new study by an international team of scientists. Its findings reveal parallels with the behavior of animals, such as rats, in seeking food rewards.

Retroviruses are re-writing the koala genome and causing cancer Posted: 26 Feb 2021 07:38 AM PST Koalas are facing multiple environmental and health issues which threaten their survival. Along with habitat loss - accelerated by last year's devastating bush fires - domestic dog attacks and road accidents, they suffer from deadly chlamydial infections and extremely high frequency of cancer. Scientists now demonstrate that a retrovirus invading the koala germline explains the high frequency of koala cancer.

Microbes deep beneath seafloor survive on byproducts of radioactive process Posted: 26 Feb 2021 07:38 AM PST Researchers found that microbes living in ancient sediment below the seafloor are sustained primarily by chemicals created by the natural irradiation of water molecules. Results of this research may have implications for life on Mars.
