COVID-19: genetic network analysis provides ‘snapshot’ of pandemic origins

COVID-19: genetic network analysis provides ‘snapshot’ of pandemic origins

Google Tag ManagerPhylogenetic network analysis has the potential to help identify undocumented COVID-19 infection sourcesPeter ForsterResearchers from Cambridge, UK, and Germany have reconstructed the early “evolutionary paths” of COVID-19 in humans – as infection spread from Wuhan out to Europe and North America – using genetic network techniques.By analysing the first 160 complete virus genomes to be sequenced from human patients, the scientists have mapped some of the original spread of the new coronavirus through its mutations, which creates different viral lineages.“There are too many...

3D printed corals could improve bioenergy and help coral reefs

Google Tag ManagerWe hope that our technique will be scalable so it can ultimately reduce greenhouse gas emissions that are responsible for coral reef deathDaniel WangpraseurtResearchers from Cambridge University and University of California San Diego have 3D printed coral-inspired structures that are capable of growing dense populations of microscopic algae. Their , reported in the journal Nature Communications, open the door to new bio-inspired materials and their applications for coral conservation.In the ocean, corals and algae have an intricate symbiotic relationship. The coral...

‘Wild West’ mentality lingers in US mountain regions

‘Wild West’ mentality lingers in US mountain regions

Google Tag ManagerThis psychological fingerprint for mountainous areas may be an echo of the personality types that sought new lives in unknown territoriesFriedrich GötzWhen historian Frederick Jackson Turner presented his famous thesis on the US frontier in 1893, the “coarseness and strength combined with acuteness and acquisitiveness” it had forged in the American character.Now, well into the 21st century, and researchers led by the University of Cambridge have detected remnants of the pioneer personality in US populations of once inhospitable mountainous territory, particularly in the...

AI shows how hydrogen becomes a metal inside giant planets

AI shows how hydrogen becomes a metal inside giant planets

Google Tag ManagerThe existence of metallic hydrogen was theorised a century ago, but what we haven’t known is how this process occursBingqing ChengDense metallic hydrogen – a phase of hydrogen which behaves like an electrical conductor – makes up the interior of giant planets, but it is difficult to study and poorly understood. By combining artificial intelligence and quantum mechanics, researchers have found how hydrogen becomes a metal under the extreme pressure conditions of these planets.The researchers, from the University of Cambridge, IBM Research and EPFL, used machine learning to...

Focus on COVID-19 deaths in under-65’s for better insights into infection rates across populations, say researchers

Focus on COVID-19 deaths in under-65’s for better insights into infection rates across populations, say researchers

Google Tag ManagerMost deaths are in older people, but they are the least comparable across countries.Megan O’DriscollThe , conducted by scientists at the University of Cambridge and the Institut Pasteur, was published today in the leading journal Nature. It highlights how large COVID-19 outbreaks in European nursing homes, and the potential for missing deaths in some Asian and South American countries, have skewed COVID-19 death data for older age groups, rendering cross-country comparisons of the scale of the pandemic inaccurate.The researchers say that reporting of deaths from COVID-19...

New drone technology advances volcanic monitoring

New drone technology advances volcanic monitoring

Google Tag ManagerThese aerial measurements are pushing the frontiers of the current state-of-the-art in volcano monitoringEmma LiuThe team, involving 20 researchers from seven countries, used long-range drones kitted out with a range of lightweight sensors to study the Manam volcano - one of the most active volcanoes in Papua New Guinea.Their , published in the journal Science Advances, show how combined measurements from the air, earth and space can be used to understand volcanic contributions to the global carbon cycle, key to sustaining life on Earth.One of the best ways to detect signs...

How machine learning can help to future-proof clinical trials in the era of COVID-19

How machine learning can help to future-proof clinical trials in the era of COVID-19

Google Tag ManagerIt is my hope that machine learning will not only improve the execution and evaluation of clinical trials in the COVID-19 era, but also well beyond thatMihaela van der SchaarIn an published in Statistics in Biopharmaceutical Research, an international collaboration of data scientists and pharmaceutical industry experts – led by the Director of the , Professor of the University of Cambridge – describes the impact that COVID-19 is having on clinical trials, and reveals how the latest machine learning (ML) approaches can help to overcome challenges that the pandemic...

Astronomers discover the first ‘ultrahot Neptune’: one of nature’s improbable planets

Astronomers discover the first ‘ultrahot Neptune’: one of nature’s improbable planets

Google Tag ManagerThis planet is particularly exciting because of its peculiarity: how did this planet come to arrive on such a short period orbit and why does it still possess an atmosphere?Ed GillenThe planet orbits so close to its star that its year lasts only 19 hours, and stellar radiation heats the planet to over 1700 degrees Celsius.At these temperatures, heavy elements like iron can be ionised in the atmosphere and molecules disassociated, providing a unique laboratory to study the chemistry of planets outside the solar system.Although the planet weighs twice as much as Neptune, it...

Many ventilation systems may increase risk of COVID-19 exposure, study suggests

Many ventilation systems may increase risk of COVID-19 exposure, study suggests

Google Tag ManagerAs winter approaches in the northern hemisphere and people start spending more time inside, understanding the role of ventilation is critical to estimating the risk of contracting the virus and helping slow its spreadPaul LindenA team from the University of Cambridge found that widely-used ‘mixing ventilation’ systems, which are designed to keep conditions uniform in all parts of the room, disperse airborne contaminants evenly throughout the space. These contaminants may include droplets and aerosols, potentially containing viruses.The research has highlighted the...

Melting Ice Reveals Lost Viking Mountain Pass | Department of Archaeology

Melting Ice Reveals Lost Viking Mountain Pass | Department of Archaeology

Search site Submitted by on Thu, 16/04/2020 - 08:35.The retreating mountain glaciers of Norway have revealed a host of rare archaeological finds and uncovered a lost mountain pass at Lendbreen in Innlandet County. The finds tell a remarkable story of high-altitude travel and long distance exchange c. 300 – 1500 AD with a peak in usage c. 1000 AD during the Viking Age. A team of archaeologists from Norway and Cambridge have published details of these artefacts today in the journal .“A lost mountain pass melting out of the ice is a dream discovery for glacial archaeologists,” says Lars Pilø,...
