  The principles of acoustic ejection mass spectrometry: an interview with Chang Liu /  I principi della spettrometria di massa ad espulsione acustica: un'intervista a Chang Liu Segnalato dal Dott. Giuseppe Cotellessa /  Reported by Dr. Giuseppe Cotellessa What is  acoustic ejection mass spectrometry (AEMS)  and how does it work? There are two critical parts in the AEMS technology. The first part is the Acoustic Droplet Ejection (ADE) module, which uses the focused acoustic energy to non-contact eject sample droplets out of the standard microplates. Another part of the AEMS system is the Open-Port Interface (OPI), which is positioned above the microplate. The continuous liquid flow in OPI captures the acoustically dispensed sample droplets and delivers it to the standard ESI-MS for the high-throughput readout. The integration of ADE with OPI is a like a perfect marriage. We bring the fast, precisely controlled, low-volume sampling to the direct liquid transferring sampling interfac

 Does coronavirus spread more easily in cold temperatures? Here’s what we know /  Il coronavirus si diffonde più facilmente a basse temperature? Ecco cosa sappiamo Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Giuseppe Cotellessa Why is the reported number of COVID-19 cases  rising across Europe  now? Many countries ended their full lockdowns at the start of the summer, but it wasn’t until the autumn that most places began to see a significant increase in the spread of the virus again. The re-opening of schools and universities led to greater mixing of individuals from different households, but could the fall in outside temperatures also be playing a part? We know that more people get colds and flu  in the winter  (the colds can be caused by types of coronavirus), but there are several potential reasons for this. It’s often attributed to the fact that people  spend more time indoors  when it’s colder, coughing, sneezing and breathing on each other. You are more likely to c

A lint-free wipe with 19 per cent fibre density sanitised up to 82 per cent of escaped respiratory droplets by volume. Such fabrics do not

Giuseppe Cotellessa /  Reported by Dr. Giuseppe Cotellessa The landmark event, which came after seven years of construction and £55m in EPSRC funding, brings the UK closer to building its first fusion power plant by 2040. In a statement, UKAEA CEO, Professor Ian Chapman, said: “ MAST Upgrade   will take us closer to delivering sustainable, clean fusion energy. This experiment will break new ground and test technology that has never been tried before. It will be a vital testing facility on our journey to delivering the STEP fusion power plant.” Fusion energy is achieved by fusing hydrogen particles in a hot gas – plasma – to unlock large amounts of energy. It is seen as having the potential to deliver abundant, inherently safe low-carbon electricity, but operating fusion technologies requires the exact control of extreme heat, gas and powerful magne

Giuseppe Cotellessa /  Reported by Dr. Giuseppe Cotellessa È morto in ospedale a  Rovigo , la notte scorsa, Giacomo Magaraggia figlio del noto politico rodigino Roberto, ex presidente della società partecipata As2. Giacomo, che aveva solo 34 anni, era stato colpito da febbre e da un malore. Nella notte tra venerdì 30 e sabato 31 ottobre, la situazione è precipitata e nonostante le cure della terapia intensiva non si è ripreso. Secondo le verifiche fatte in ospedale, a seguito dei  protocolli Covid che prevedono il tampone in caso di febbre, non era positivo al virus che prevedono il tampone in caso di febbre ENGLISH Giacomo Magaraggia, son of the well-known politician from Rovigo, Roberto, former president of the subsidiary company As2, died last night in the hospital in Rovigo.

Epigenetic Clock Developed to Help Study Brain Aging and Dementia /  Orologio epigenetico sviluppato per aiutare a studiare l'invecchiamento cerebrale e la demenza Segnalato dal Dott. Giuseppe Cotellessa /  Reported by Dr. Giuseppe Cotellessa While most of us are probably familiar with the concept of the circadian body clock, which dictates our rhythms of sleep or wakefulness, a relatively new concept known as the epigenetic clock could inform us about how swiftly our bodies age, and how prone we are to diseases of old age. Scientists at the University of Exeter have now developed a new epigenetic clock specifically for the human brain. Developed using human brain tissue samples, the new model is claimed to be far more accurate for the human brain than previous versions that were based on blood samples or other tissues. The researchers hope that it will provide new insights into how accelerated aging in the brain could be associated with brain disorders such as Alzheimer’s disease
