  1. New research shows that high levels of microplastics (MPs) are released from infant-feeding bottles (IFBs) during formula preparation. The research also indicates a strong relationship between heat and MP release, such that warmer liquids (formula or water used to sterilize bottles) result in far greater release of MPs. The work underlines the need for appropriate mitigation strategies and new plastic technologies.
  2. With a new material, the greenhouse gas carbon dioxide (CO2) can be specifically separated from industrial waste gases, natural gas, or biogas, and thereby made available for recycling. The separation process is both energy efficient and cost-effective.
  3. As the world grapples with COVID-19, the Ebola virus is again raging. Researchers are using supercomputers to simulate the inner workings of Ebola (as well as COVID-19), looking at how molecules move, atom by atom, to carry out their functions. Now, they have revealed structural features of the Ebola virus's protein shell to provide therapeutic targets to destabilize the virus and knock it out with an antiviral treatment.
  4. Gene editing for the development of new treatments, and for studying disease as well as normal function in humans and other organisms, may advance more quickly with a new tool for cutting larger pieces of DNA out of a cell's genome, according to a new study.
  5. Now that autumn is upon us, there is a large temperature gap between day and night. This is due to the temperature inversion caused by radiative cooling on the Earth's surface. Heat from the sun during the day causes its temperature to rise and when the sun sets during the night, its temperature cools down. Recently, a research team has demonstrated a daytime radiative cooling effect which exhibits lower temperatures than its surroundings even during the day.
  6. Membranes with microscopic pores are useful for water filtration. The effect of pore size on water filtration is well-understood, as is the role of ions, charged atoms, that interact with the membrane. For the first time, researchers have successfully described the impact water molecules have on other water molecules and on ions as part of the filtration mechanism. The researchers detail a feedback system between water molecules which opens up new design possibilities for highly selective membranes. Applications could include virus filters.
  7. Researchers have created the prototype for a hand-held device to measure a biomarker for cancer, paving the way for home-based cancer monitoring and to improve access to diagnostic testing.
  8. The lessons learned from a near infrared absorbing, bowl-shaped molecule made only from hydrogen and carbon atoms offers insights for future organic conductors.
  9. Researchers have applied photolithographic techniques from the computer chip industry to enzymatic DNA synthesis, and thus developed a new method to multiplex the superior DNA writing ability of Terminal deoxynucleotidyl Transferase TdT's.
  10. Thin tissue grafts and flexible electronics have a host of applications for wound healing, regenerative medicine and biosensing. A new device inspired by an octopus's sucker rapidly transfers delicate tissue or electronic sheets to the patient, overcoming a key barrier to clinical application.
