Could acid-neutralising life-forms make habitable pockets in Venus’ clouds?
A new study shows it's theoretically possible. The hypothesis could be tested soon with proposed Venus-bound missions. If life is there, how does it propagate in an environment as dry as the clouds of Venus? Paul Rimmer It's hard to imagine a more inhospitable world than our closest planetary neighbour.

’Wonder material’ phosphorene nanoribbons live up to hype in first demonstration
Phosphorene nanoribbons have been incorporated into new types of solar cells, dramatically improving the cells' efficiency, in a new study led by UCL and Imperial College London researchers. Phosphorene nanoribbons (PNRs) are ribbon-like strands of the 2D material phosphorous, which, similar to graphene, are made of single-atom-thick layers of atoms.

Could life be making its own habitable environment in the clouds of Venus?
Scientists have proposed a new theory which suggests that possible lifeforms in the clouds of Venus could be setting off a cascade of chemical reactions that is making the environment much more habitable. This self-sustaining chain of events could also explain many of the strange anomalies present in the planet's upper atmosphere that have been puzzling scientists for decades.

Link found between gum disease and other illness such as mental health and heart conditions
A University of Birmingham-led study shows an increased risk of patients developing illnesses including mental ill-health and heart conditions if they have a GP-inputted medical history of periodontal (gum) disease. Experts carried out a first of its kind study of the GP records of 64,379 patients who had a GP-inputted recorded history of periodontal disease, including gingivitis and periodontitis (the condition that occurs if gum disease is left untreated and can lead to tooth loss).

Drug could more effectively treat patients hospitalised with COVID-19 pneumonia, early stage research finds
A proof-of-concept trial led by the University of Birmingham and University Hospitals Birmingham NHS Foundation Trust has identified a drug that may benefit some patients hospitalised with COVID-19 pneumonia. The CATALYST trial tested UK-based bio-pharmaceutical company Izana Bioscience's namilumab (IZN-101) as a potential therapeutic to treat patients who are hospitalised with COVID-19 pneumonia, and receiving 'usual' care, as well as having high levels in their blood of a marker of inflammation known as C reactive protein (CRP).

Sauropod dinosaurs were restricted to warmer regions of Earth
Giant, long-necked sauropods, thought to include the largest land animals ever, preferred to live in warmer regions on Earth, suggesting they may have had a different physiology from other dinosaurs, finds a new study led by researchers at UCL and the University of Vigo. The study, published in the journal Current Biology , investigated the enigma of why sauropod fossils are only found at lower latitudes, while fossils of other main dinosaur types seem ubiquitously present, with many located in the polar regions.

Omicron may cause 100,000 cancelled operations in England this winter
An additional 100,000 elective operations could be cancelled in England this winter as a result of the Omicron wave leading to increased hospital admissions, a new study reveals. The modelling study, published as a peer-reviewed research letter in The Lancet, finds that the number of elective operations performed each week is closely related to the number of patients in hospital with COVID-19.

Theropod dinosaur jaws became stronger as they evolved - study
Theropod dinosaurs evolved more robust jaws through time allowing them to consume tougher food, a new study reveals. Researchers used digital modelling and computer simulation to uncover a common trend of jaw strengthening in theropods - expanding the rear jaw portion in all groups, as well as evolving an upturned jaw in carnivores and a downturned jaw in herbivores.

Psychological impact of pandemic on UK nursing and midwifery workforce
Extremely concerning levels of psychological distress are reported in results from a longitudinal study of the UK nursing and midwifery workforce during COVID-19 led by the University of Warwick. The findings could help how staff are supported in healthcare services now and in future. The results from surveys of the UK nursing and midwifery workforce taken at three time points during the first wave of the pandemic in 2020 have found concerning levels of psychological distress, including experiences consistent with post-traumatic stress disorder (PTSD), stress, and anxiety in respondents.

Gentrification changes the personality make-up of cities in just a few years
Massive study of almost two million US residents reveals rising housing costs may drive increases in "openness" of character among both long-term and new inhabitants of a city. Substantial personality shifts within cities can and do occur within a couple of years Jason Rentfrow Rising house prices may change the personality make-up of US cities within a few years, with residents becoming increasingly open-minded - not just as wealthier people move in, but also among longer-term locals.

New approach to predicting battery failure could help maintain electricity for millions around the world
The new method of predicting battery failure is 15 - 20% more accurate than current approaches. Millions of people around the world lack access to electricity. Decentralised solar-battery systems are key for addressing this whilst avoiding carbon emissions and air pollution, but are hindered by relatively high costs and rural locations that inhibit timely preventative maintenance.
