Worlds fastest genome sequencer diagnoses genetic disease in hours
17.1.2022 | Press monitoring
A research effort led by Stanford scientists set the first Guinness World Record for the fastest DNA sequencing technique, which was used to sequence a human genome in just 5 hours and 2 minutes. A new ultra-rapid genome sequencing approach developed by Stanford Medicine scientists and their collaborators was used to diagnose rare genetic...
Synthetic gene circuits that improve stem cell quality
14.1.2022 | Press monitoring
Because iPS cells can be made into just about any cell type in the body, they have great promise for cell therapies. One major problem, however, is that not all reprogramming cells successfully become iPS cells, resulting in an unwanted cell mixture. Further, when differentiating iPS cells, some cells are only partially differentiated, again...

Oxford cancer blood test detects tumors and metastasis early
12.1.2022 | Press monitoring
Being able to go into a doctor’s office for a routine blood test to check for cancer would save countless lives, so of course the idea has attracted much scientific study. Different tests have searched for different biomarkers associated with cancer, such as elevated levels of certain proteins, DNA mutations, RNA profiles of blood platelets,...
Superbug MRSA arose in hedgehogs long before clinical use of antibiotics
10.1.2022 | Press monitoring
Staphylococcus aureus first developed resistance to the antibiotic methicillin around 200 years ago, according to a large international collaboration including the University of Cambridge, the Wellcome Sanger Institute, Denmark's Serum Statens Institut and the Royal Botanic Gardens, Kew, which has traced the genetic history of the bacteria. They...
Zoo experiments detect dozens of animals from airborne DNA
7.1.2022 | Press monitoring
Animals are constantly shedding DNA into their environment, traces of which can then be detected in soil and water – and now, perhaps even air. Two new studies collected air samples from zoos and were able to identify a range of animals living in and around the facilities, which could eventually be used as a non-invasive way to track...

Lychee genome tells a colorful story about a colorful tropical fruit
5.1.2022 | Press monitoring
Lychees have been grown in China since ancient times, with records of cultivation dating back about 2,000 years. Fresh lychees were an object of such desire that in the Tang Dynasty, one emperor set up a dedicated horse relay to deliver the fruits to the imperial court from harvests made far to the south. Now, scientists have used genomics to...

Slug-slime-inspired biomaterial speeds repair of injured tendons
3.1.2022 | Press monitoring
Injured tendons are notoriously tricky to repair. Researchers at Harvard’s Wyss Institute have now developed a two-faced biomaterial that can improve healing, with one side that firmly sticks to tendons, while a low-friction outer surface keeps it gliding against other tissues. Better yet, they can be loaded with slow-release drugs to reduce...
Speeding up directed evolution of molecules in the lab using a new robotic platform
31.12.2021 | Press monitoring
Natural evolution is a slow process that relies on the gradual accumulation of genetic mutations. In recent years, scientists have found ways to speed up the process on a small scale, allowing them to rapidly create new proteins and other molecules in their lab. This widely-used technique, known as directed evolution, has yielded new antibodies...

Intestine organoid grown in lab to study why bats live with viruses but dont get sick
29.12.2021 | Press monitoring
Experiments attempting to explain why bats can be infected with many viruses at a time without succumbing to diseases such as COVID-19 – knowledge that could help us to reduce the threat to humans of infectious disease – have struggled until now with the fact that live wild bats make poor research subjects. To overcome this obstacle, for the...
Bacterial battle: How protective cultures can protect us from food-borne pathogens in cheese
27.12.2021 | Press monitoring
Cheese is a simple product. It usually only consists of milk, enzymes, salt, and bacteria that give the cheese its form and flavor. But this simplicity, free of preservatives found in other foods, leaves it vulnerable to hosting pathogens. In the cheese production process, cheese makers use starter bacterial cultures to turn milk into cheese. In...
