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.
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.
Gum disease increases risk of other illness such as mental health and heart conditions
Share this page Share on Twitter Share on facebook Share on linkedin Share on email 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).

Turbocharged data analysis could prevent gravitational wave computing crunch
A new method of analysing the complex data from massive astronomical events could help gravitational wave astronomers avoid a looming computational crunch. Researchers from the University of Glasgow have used machine learning to develop a new system for processing the data collected from detectors like the Laser Interferometer Gravitational-Wave Observatory (LIGO).

Covid-19 vaccine protection wanes after three months
Related Links Link to the study in the Lancet Covid-19 vaccine protection wanes after three months, study suggests The protection offered by the Oxford-Astra Zeneca Covid-19 vaccine declines after three months of receiving two doses, a study says. The findings - drawn from datasets in two countries - suggest that booster programmes are needed to help maintain protection from severe disease in those vaccinated with Oxford-Astra Zeneca, experts say.

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.

The NASA-led James Webb Space Telescope, which includes hardware designed and built at UCL and which will image the very first stars to shine in the Universe, is scheduled to be launched into space later this month. The telescope, one of the great space observatories following Hubble, will be launched on-board the Ariane rocket from Europe's spaceport in French Guiana on or after Friday 24 December.
How did lockdown affect people’s sex lives in Britain?
Lockdown affected people's sex lives in a variety of different ways with young people and those not living with a partner reporting the greatest changes, according to researchers from UCL, the University of Glasgow and the National Centre for Social Research (NatCen). The peer-reviewed paper, which is the largest national study of sexual behaviours since the beginning of the pandemic, is published today in BMJ Sexually Transmitted Infections.

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.

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.

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.

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.
Researchers in the UK and China have developed an artificial intelligence (AI) model that can diagnose COVID-19 as well as a panel of professional radiologists, while preserving the privacy of patient data. By working with other countries, we can do so much more than we can alone Michael Roberts The international team, led by the University of Cambridge and the Huazhong University of Science and Technology, used a technique called federated learning to build their model.
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.

New insights into impact of immune-suppressing treatments on COVID-19 vaccine effectiveness
Treatments used to help people with multiple sclerosis (MS) manage their condition can reduce the effectiveness of COVID-19 vaccines, according to a new study led by Cardiff University. Disease-modifying therapies (DMTs) are a group of treatments that suppress the body's immune system and are used by people with MS and other conditions such as cancer and rheumatoid disease.

The technologies behind one of the biggest scientific breakthroughs of the century - the detection of gravitational waves - are now being used in the long-standing search for dark matter. Thought to make up roughly 85% of all matter in the Universe, dark matter has never been observed directly and remains one of the biggest unsolved mysteries in modern physics.
