Novel RNA- or DNA-based substances can protect plants from viruses, scientists show

1.3.2024   |   Press monitoring

Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study by the Martin Luther University Halle-Wittenberg (MLU). The researchers were able to fend off a common virus using the new active substances in up to 90% of cases. They also developed a method for finding substances...

Nanotweezers manipulate bacteriophages with minimal optical power, a breakthrough for phage therapy

28.2.2024   |   Press monitoring

Scientists at EPFL have developed a game-changing technique that uses light to manipulate and identify individual bacteriophages without the need for chemical labels or bioreceptors, potentially accelerating and revolutionizing phage-based therapies that can treat antibiotic-resistant bacterial infections. Phage therapy, the use of bacteriophages...

Radioactive fruit sugar lights up cancer and inflammation

26.2.2024   |   Press monitoring

A radioactive form of fructose, a natural sugar found in fruit, given to mice lit up areas of cancer and inflammation on a diagnostic medical scan. The researchers say the approach makes diseases easier to spot than current techniques and opens the door to new avenues of early detection. A positron emission tomography or PET scan often relies on...

Mosquito-spreading drones could slash the spread of disease

23.2.2024   |   Press monitoring

First of all, how could adding mosquitos to the environment reduce the spread of malaria and other mosquito-borne diseases? Well, it all comes down to a process known as "sterile insect technique" (SIT). In a nutshell, SIT involves rendering captive male mosquitos sterile, then releasing them into areas where wild female mosquitos are present....

Synthetic antibody could be key to a universal antivenom

21.2.2024   |   Press monitoring

Scientists have made a synthetic antibody that can prevent paralysis and death inflicted by the venom of elapids, a large family of mostly deadly snakes found around the world. The discovery has us slithering ever closer to developing a single, universal antivenom that could protect us against all venomous snakes. Australia, Asia, and Africa, in...

Grow a pair: Lab-grown testicles tackle infertility treatment

19.2.2024   |   Press monitoring

Researchers have created lab-grown testicle organoids that closely resemble the real thing. The breakthrough provides a promising model for research that may advance our understanding of the organs' development and translate into therapeutic applications for male infertility. Organoids, lab-grown 3D mini-organs derived predominantly from stem...

Vibrio natriegens: Low-cost microbe could speed biological discovery

16.2.2024   |   Press monitoring

Cornell University researchers have created a new version of a microbe to compete economically with E. coli – a bacteria commonly used as a research tool due to its ability to synthesize proteins – to conduct low-cost and scalable synthetic biological experiments. As an inexpensive multiplier – much like having a photocopier in a test tube – the...

Drug-loaded nanoparticles may prevent paralysis from spinal cord injury

14.2.2024   |   Press monitoring

Sustaining a spinal cord injury (SCI) is devastating enough, but the subsequent inflammation and the damage it causes to the spinal cord can worsen the clinical outcome. This secondary injury can develop over time and lead to paraplegia or quadriplegia that may not have been present at the time of the primary injury. Research has shown that in...

Bacterias natural self-destruct mechanism used to fight infections

12.2.2024   |   Press monitoring

A new study has demonstrated that a natural bacterial defense mechanism against invading viruses can be used as a weapon to combat bacterial infection. The finding opens the door to new anti-bacterial therapeutics, particularly important in the face of rising antibiotic resistance. When certain bacteria are infected by a virus, they initiate a...

Medical lab-on-a-chip runs 32 pathology tests at once

9.2.2024   |   Press monitoring

Diagnosing diseases early benefits patients and doctors. It enables treatment to slow disease progression and reduces the risk of complications, thereby improving long-term health outcomes. With early diagnosis in front of mind, a team from Helmholtz-Zentrum Dresden-Rossendorf (HZDR) research laboratory in Germany has used off-the-shelf...
