NewsNew blood test cuts infection diagnosis time from months to hours
Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours.

NewsPowerful new AI can predict people’s attitudes to vaccines
A powerful new tool in artificial intelligence is able to predict whether someone is willing to be vaccinated against COVID-19. The predictive system uses a small set of data from demographics and personal judgments such as aversion to risk or loss.

NewsBacteria subtype linked to growth in up to 50% of human colorectal cancers
A new study suggests that a subtype of Fusobacterium nucleatum underlies colorectal cancer growth in humans and could be useful in screening and treatments.

NewsExperts warn climate change will fuel spread of infectious diseases
A team of infectious diseases experts called for more awareness and preparedness in the medical field to deal with the impact of climate change on the spread of diseases. Their article, published in JAMA, raises the alarm about the emergence and spread of harmful pathogens. The authors ...

NewsProtein found in human sweat may protect against Lyme disease
Researchers also found that a variant of the protein is not as protective against the bacterium and increases susceptibility to the disease.

NewsSARS-CoV-2 spike protein sensitizes pain receptors in mice
A study aiming to investigate whether the spike protein of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) can sensitize nociceptors and promote pain-like behaviors in mice was presented at the 102nd General Session of the IADR.

NewsResearchers investigate how freshwater diatoms stay in the light
Scientists sampled the ice-covered (in 2019) and ice-free (in 2020) winter waters of Lake Erie to learn how diatoms are responding to changing environmental conditions.

NewsRapid specific detection of oral pathogens using CRISPR-based diagnostics
A study aiming to develop a low-cost, rapid detection technique for the widescale detection and screening of oral microorganisms suitable for point-of-care settings was presented at the 102nd General Session of the IADR.

NewsTeardrops target multiple COVID variants through the twist in the spike protein
Particles that gum up the keys that the virus uses to enter cells could one day be an effective COVID treatment whenever vaccines and other treatments fall short.

NewsResearchers explore role of salps as predators of marine microbes
Salps play a major role in controlling the abundances and function of microbial communities in the vast nutrient-poor open ocean, with global implications, a new study reveals.

NewsResearchers support increased genomic sequencing of dengue for more effective prevention
Molecular epidemiologic data from whole-genome sequencing of dengue serotypes could enhance dengue outbreak preparedness, researchers say.
-
NewsDrug candidate may ‘unmask’ latent HIV-infected cells, mark them for destruction
Scientists have identified drug candidates that show promise to reverse the ability of HIV to escape detection by the immune system.
-
NewsClimate change alters the hidden microbial food web in peatlands
A study of protists shows that a neglected part of the peatlands’ microbial food web is sensitive to climate change, and in ways that are currently not accounted for in models that predict future warming.
-
NewsDaff-derived Alzheimer’s drug fermented with help from AI and bacteria moves closer to reality
An innovative approach uses artificial intelligence and biosensors to pave the way for faster drug development.

NewsStudy reveals how hydrogen supplied energy at life’s origin
A new report uncovers how hydrogen gas provided energy in the past, at the origin of life 4 billion years ago.
-
NewsGut bacteria make neurotransmitters to shape the newborn immune system
Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.
-
NewsNewborn piglets serve as a model for studying influenza
A multidisciplinary team of researchers has studied newborn piglets to better understand the progression of influenza infections.
-
NewsResearchers report rise in global fungal drug-resistant infections
Epidemiological data indicates that a rise in severe fungal infections has resulted in over 150 million cases annually and almost 1.7 million fatalities globally.
-
NewsStudy details how low humidity could be a boon for viruses
In reaction to the threat of COVID-19 and other viral, airborne respiratory infections, experts have recommended increased ventilation in hospitals, nursing homes, schools, and other public buildings. However, new research from Stanford University suggests that excess ventilation can reduce relative humidity in a way that could counteract ...

NewsMutation linked to neurological disorders delivers double-pronged attack at cellular level
A mutation linked to neurological disorders knocks out not just one protein involved in translating the genetic code, but the entire cellular translation machinery. That’s the discovery of a team from the University of Maryland who were investigating how editing defects in threonyl-tRNA synthetase (ThrRS) work at ...
