NewsAntibiotics do not reduce risk of dying in adults hospitalised with common respiratory infections, suggests study
Most patients admitted to hospital with acute viral respiratory infections are given antibiotics. Now new research to be presented at this year’s ECCMID in Copenhagen suggests that prescribing antibiotic therapy to adults hospitalised with common viral respiratory infections such as influenza is unlikely to save lives.

NewsResearchers discover previously unknown Achilles heel of Covid virus
Scientists concluded that only a survey of neutralising antibodies can inform us about protection against new Covid infections, then disovered a previously unknown weak point of the virus when analysing specific characteristics of those antibodies.

FeaturesCannabis: The new antiviral hero?
Despite its long history of use, the plant remains largely misunderstood and stigmatised in many parts of the world.

NewsViruses that kill cancer cells show promise for triple-negative breast cancer when combined with chemo
Researchers have shared positive results from a phase 2 clinical trial of an oncolytic virus combined with standard chemotherapy in patients with early stage triple-negative breast cancer.

NewsScientists find two separate reservoirs of latent HIV in patients
Scientists have shown that, addition to HIV’s ability to lay dormant in the blood/lymphoid system, the virus may also lay dormant in the central nervous system, delineating another challenge in creating a cure.

NewsVirologists call for ‘rational discourse’ on gain of function research
The study of viruses is under renewed scrutiny, say more than 150 experts in a commentary whose authors call on policymakers to recognize the need for more rational discourse around the future of virology, ahead of a meeting of the National Science Advisory Board for Biosecurity .

NewsComputer model of influenza virus shows universal vaccine promise
Researchers have created an atomic-level computer model of the H1N1 virus that reveals new vulnerabilities, suggesting possible strategies for the design of future vaccines and antivirals against influenza.
-
NewsStunningly detailed blueprint revealed of viral genome replication machinery
Scientists have shed new light on the crucial early stages of RNA virus infection and their control.
-
NewsResearchers develop electrochemical biosensor for flu antibody detection
A new testing method uses an electrochemical cell-free biosensor that can directly detect antibodies against diseases such as influenza in blood serum.
-
NewsChange in genetics of SARS-CoV-2 evolved to counter weakness caused by the virus’s initial mutation
Researchers at Johns Hopkins Medicine say their new studies suggest that the first pandemic-accelerating mutation in the SARS-CoV-2 virus, which causes COVID-19, evolved as a way to correct vulnerabilities caused by the mutation that started the SARS-CoV-2 pandemic.
-
OpinionManufacturing certainty on the origin of Covid-19 is damaging to science
Alina Chan reveals why it’s dangerous to insist that the lab leak theory is dead in the water.

NewsSimple nasal swab can provide early warning of emerging viruses
Testing for the presence of a single immune system molecule on nasal swabs can help detect stealthy viruses not identified in standard tests, Yale researchers have found.

NewsOlfactory viral inflammation linked to accelerated onset of Alzheimer’s disease
Viruses can inflame and disrupt connections between the olfactory system, which governs the sense of smell, and the part of the brain associated with memory and learning, possibly accelerating the onset of Alzheimer’s disease, according to a new study.

NewsScientists identify infection-halting compound that can target hosts, not viruses
Researchers at UBC’s Life Sciences Institute have identified a compound that shows early promise at halting infections from a range of coronaviruses, including all variants of SARS-CoV-2 and the common cold.
-
NewsPhase 2 trial of Ebola vaccines yields promising results
An international team of scientists has published the results of a large-scale randomized clinical trial in West Africa which confirms the safety of three vaccine regimens for Ebola and suggests an immune response is induced and maintained for up to 12 months.

NewsResearchers infect ‘brain in a dish’ in pursuit of Zika antivirals
A University of Queensland-led project has used a ‘brain in a dish’ to study the effects of the Zika virus, taking research a step closer towards developing drugs to combat the infection.
-
NewsPotential drug takes aim at emerging Chikungunya virus
Researchers are developing what could become the first-ever treatment against the debilitating joint pain that can last months or years after becoming infected with the emerging Chikungunya virus.

News New virus discovered in Swiss ticks
Researchers from the Institute of Virology at the University of Zurich (UZH) have detected the Alongshan virus (ALSV) for the first time in ticks in Switzerland.

NewsResearchers find new viral entryway into host cells for Covid-19
A University of Ottawa-led team has found a new viral entry for SARS-CoV-2, suggesting it may be able to use proteins to infect a wider range of cells.

NewsImmune response discovery solves mystery of why colds are more common when it’s cold
Scientists say a newly discovered immune response inside the nose is suppressed by colder temperatures, offering evidence for why colds, flu and COVID-19 are more common in cooler months.
