Zika and yellow fever-vaccines without eggs

26.9.2018   |   Press monitoring

A team led by researchers from the Max Planck Institute for Dynamics of Complex Technical Systems in Magdeburg is developing methods with which viruses for vaccines can be replicated in significantly higher concentrations than before. The researchers produce the pathogens in cell cultures in small bioreactors. The production of vaccines currently...

Mosquitoes that can carry malaria eliminated in lab experiments

24.9.2018   |   Press monitoring

The team from Imperial College London were able to crash caged populations of the malaria vector mosquito Anopheles gambiae in only 7-11 generations. This is the first time experiments have been able to completely block the reproductive capacity of a complex organism in the laboratory using a designer molecular approach. The technique, called...

Scientists grow human esophagus in lab

21.9.2018   |   Press monitoring

Scientists working to bioengineer the entire human gastrointestinal system in a laboratory now report using pluripotent stem cells to grow human esophageal organoids. The study is the latest advancement from researchers at the Cincinnati Children's Center for Stem Cell and Organoid Medicine (CuSTOM). The center is developing new ways to study...

Nitrogen fixation engineering in cereal crops moves a step closer

19.9.2018   |   Press monitoring

One of the major factors that limit crop growth is the availability of nitrogen, but only bacteria and other single-celled microbes called archaea can take nitrogen from the air and fix it into a form that can be used by plants. The process carried out by these microbes is known as biological nitrogen fixation. Legumes obtain nitrogen from...

Stem cells from baby teeth patch up dental injuries in clinical trial

14.9.2018   |   Press monitoring

Your teeth are one of the only parts of your body that can't naturally repair themselves – so when a kid injures a permanent tooth at a young age, they're stuck with that for life. But a new clinical trial has shown promising results in using dental stem cells derived from a patient's baby teeth to bring a "dead" tooth back to life. The...

Unleashing TIGER on small RNAs

12.9.2018   |   Press monitoring

Efforts to explore the landscape of small RNAs (sRNAs) – short RNA molecules that are poorly understood – often use high-throughput sequencing (sRNA-seq). These efforts are hampered by a lack of tools to identify, quantify and analyze all the different sRNAs in sRNA-seq datasets. Kasey Vickers, PhD, and colleagues have now developed a new...

Superbugs jumping frequently between humans and animals

10.9.2018   |   Press monitoring

MRSA staphylococcus is an example of a superbug. These bacterial strains are resistant to most antibiotics and can cause serious infections. "In the case of MRSA, these bacteria have also spread in hospitals almost worldwide," says Jukka Corander, professor at the University of Helsinki, a member of an international research team that mapped...

Neutrophil nanosponges soak up proteins that promote rheumatoid arthritis

7.9.2018   |   Press monitoring

Engineers at the University of California San Diego have developed neutrophil "nanosponges" that can safely absorb and neutralize a variety of proteins that play a role in the progression of rheumatoid arthritis. Injections of these nanosponges effectively treated severe rheumatoid arthritis in two mouse models. Administering the nanosponges...

Scientists decode opium poppy genome

5.9.2018   |   Press monitoring

Scientists have determined the DNA code of the opium poppy genome, uncovering key steps in how the plant evolved to produce the pharmaceutical compounds used to make vital medicines. The discovery may pave the way for scientists to improve yields and the disease resistance of the medicinal plant, securing a reliable and cheap supply of the most...
