Paper filter from local algae could save lives in Bangladesh

Paper filter from local algae could save lives in Bangladesh

Press releases   •   Aug 19, 2019 06:30 BST

​The problem of access to safe drinking water in most parts of Bangladesh is a persistent challenge. Now, a team of scientists shows that a locally growing and previously unexploited green macroalgae species could be used to extract cellulose nanofibers, which can then be formed into paper sheets with tailored pore size that are utilized for point-of-use water treatment.

Tiny droplets open the doors to in-flight imaging of proteins

Press releases   •   May 03, 2019 19:00 BST

For the first time, researchers have demonstrated the creation of a beam of nanodroplets capable of delivering a variety of biological samples, from cell organelles to single proteins, virtually free from any contaminations, to the focus of an X-ray laser which can be used to image them.

Hard-to-detect antibiotic resistance an underestimated clinical problem

Press releases   •   Feb 11, 2019 16:00 GMT

When antibiotics are used to treat bacteria susceptible to them, the treatment usually works. Nevertheless, the antibiotic chosen is sometimes ineffective. One of the reasons for this is heteroresistance, a phenomenon explored in depth by Uppsala and Emory University researchers in a new study.

The 210-million-year-old Smok was crushing bones like a hyena

The 210-million-year-old Smok was crushing bones like a hyena

Coprolites, or fossil droppings, of the dinosaur-like archosaur Smok wawelski contain lots of chewed-up bone fragments. This led researchers at Uppsala University to conclude that this top predator was exploiting bones for salt and marrow, a behavior often linked to mammals but seldom to archosaurs.

Figure - When the size of the droplets is much larger than the sample (top) any impurities in the surrounding solution will dry out on top the sample. As the initial droplet size is reduced, to match the size of the sample, this problem vanishes.
