A critical process in the infection cycle of viruses has been revealed for the first time in dynamic detail using pioneering plant-based technology.
Evidence about the process of virus maturation revealed in the research could help us develop new methods for treating viral infections.
Maturation plays a critical role for all animal and bacterial viruses and is required to produce infectious virions or particles. Though the outlines of the process have been determined for many groups of viruses, detailed mechanistic studies have not been reported. ....

A peptide that allows cannabis-derived drugs to relieve pain without side effects

N international team, led by researchers from UPF David Andreu and Rafael Maldonado, has developed a peptides family that allows delta-9-tetrahydrocannabinol (THC), the main component of Cannabis sativa, to fight pain in mice without side effects. ....

Scientists have made a major breakthrough in the study of embryonic development and how it can be impacted by external factors such as climate change.
Researchers at the University of Plymouth have developed a cutting edge technique which enables them to instantly examine the biological traits and behaviours of developing embryos as an energy signature, rather than focusing on individual characteristics.
The method, outlined in a study published in ....

"A Verifiable and Fair Attribute-based Proxy Re-encryption Scheme for D" by Chunpeng Ge, Willy Susilo et al.

Abstract
To manage outsourced encrypted data sharing in clouds, attribute-based proxy re-encryption (ABPRE) has become an elegant primitive. In ABPRE, a cloud server can transform an original recipient s ciphertext to a new one of a shared user s. As the transformation is computation consuming, a malicious cloud server may return an incorrect re-encrypted ciphertext to save its computation resources. Moreover, a shared user may accuse the cloud server of returning an incorrect re-encrypted ciphertext to refuse to pay the cost of using the cloud service. However, existing ABPRE schemes do not support a mechanism to achieve verifiability and fairness. In this paper, a novel verifiable and fair attribute-based proxy re-encryption (VF-ABPRE) scheme is introduced to support verifiability and fairness. The verifiability enables a shared user to verify whether the re-encrypted ciphertext returned by the server is correct and the fairness ensures a cloud server escape from malicious a ....

Just gist: Big data and pandemics in seven key points
EMBL Science and Society panel examines opportunities and limitations for big data in addressing present and future pandemics
The use of data has played a central role in the COVID-19 pandemic, but it should come as no surprise that researchers are already looking at ways to improve data acquisition, management, and access. EMBL’s most recent Science and Society seminar, ‘Harnessing Big Data to Monitor and Tackle Pandemics‘, featured a panel of three speakers who shared their experiences and conclusions about these topics.
Ilaria Capua, Director of the One Health Center of Excellence at the University of Florida, explained why the concept of ‘circular health’ could transform what we know about pandemics and how we address them. Enrico Bucci, Director of the System Biology programmes at Temple University in Philadelphia, discussed the limitations of big data and the idea of long-term pandemic ....
