Airtight corn sacks help fight hunger during the COVID-19 pandemic
Airtight corn sacks help fight hunger during the COVID-19 pandemic
Optimised on-farm grain storage boosts food security in sub-Saharan Africa, as an ETH study in Kenya during the COVID-19 pandemic shows. As the end of the lean season approaches, things get tricky for many smallholder farmers in sub-Saharan Africa. It's the time of year between harvests - the last one was a long time ago, but the next one is not yet due.

Immune cells discovered in the lungs improve virus defense
Immune cells discovered in the lungs improve virus defense
A research team at the University of Basel has discovered immune cells resident in the lungs that persist long after a bout of flu. Experiments with mice have shown that these helper cells improve the immune response to reinfection by a different strain of the flu virus. The discovery could yield approaches to developing longer-lasting vaccinations against quickly-mutating viruses.

Electrically switchable qubit can tune between storage and fast calculation modes
Electrically switchable qubit can tune between storage and fast calculation modes
To perform calculations, quantum computers need qubits to act as elementary building blocks that process and store information. Now, physicists have produced a new type of qubit that can be switched from a stable idle mode to a fast calculation mode. The concept would also allow a large number of qubits to be combined into a powerful quantum computer, as researchers from the University of Basel and TU Eindhoven have reported in the journal -Nature Nanotechnology-.

Light-based processors boost machine-learning processing
Light-based processors boost machine-learning processing
An international team of scientists have developed a photonic processor that uses rays of light inside silicon chips to process information much faster than conventional electronic chips. The exponential growth of data traffic in our digital age poses some real challenges on processing power. And with the advent of machine learning and AI in, for example, self-driving vehicles and speech recognition, the upward trend is set to continue.

Goats enjoy mental gymnastics
Goats enjoy mental gymnastics
A study on shows that goats like to earn a reward by 'working' for it, even if they can get the same reward without making any effort. This finding could benefit humane husbandry. Goats respond positively to challenges rather than just turning away. In a project funded jointly by the Swiss National Science Foundation (SNSF) and the German Research Foundation (DFG), two breeding lines - dairy goats and dwarf goats - were offered a choice of two types of reward.

Perceiving prosthesis as lighter thanks to neurofeedback
Perceiving prosthesis as lighter thanks to neurofeedback
Transmitting sensory signals from prostheses to the nervous system helps leg amputees to perceive prosthesis as part of their body. While amputees generally perceive their prostheses as heavy, this feedback helps them to perceive the prostheses as significantly lighter, ETH researchers have shown. Leg amputees are often not satisfied with their prosthesis, even though the sophisticated prostheses are becoming available.

Effectiveness of protective measures in hospitals in Ticino
A study performed in Ticino in Spring 2020, on data of SARS-CoV-2 serological tests run on healthcare workers, shows that COVID-19 antibodies are detectable in up to 10% of the participants. Such a result are comparable with the ones of the Corona Immunitas study conducted on the Ticino population. More importantly, it shows that healthcare workers with exposure to COVID-19 patients have only a slightly higher absolute risk of seropositivity than those without, suggesting that the use of protective measures in hospitals aiming at reducing nosocomial viral transmission are effective.

How to mitigate the impact of a lockdown on mental health
How to mitigate the impact of a lockdown on mental health
The Covid-19 pandemic is impacting people's mental health. But what helps and hinders people in getting through a lockdown? A new study led by researchers at the University of Basel addressed this question using data from 78 countries across the world. The results hint at the pivots and hinges on which the individual's psyche rests in the pandemic.

Packaging database for fact-checking sustainability promises
Packaging database for fact-checking sustainability promises
Researchers have created a database of over 3,000 primary and secondary packaging items from the range of the retailer Denner as a basis for ensuring more environmentally friendly packaging. The presents are unwrapped, the takeaway is eaten and the latest online order has arrived - and now there is packaging everywhere.

Peeking inside 'mini-brains' could boost understanding of the human brain in health and disease
Peeking inside ’mini-brains’ could boost understanding of the human brain in health and disease
Revealing details of the internal structure of 'mini-brains' could help accelerate drug studies and may offer alternatives to some animal testing Geneva, Switzerland, 7 January 2021 - 'Mini-brains' are pin-head sized collections of several different types of human brain cell. They are used as a tool, allowing scientists to learn about how the brain develops, study disease and test new medicines.

Persistent lung damage after Covid-19
The nationwide study published today was initiated by Inselspital, Bern University Hospital with the collaboration of the University of Bern and has established for the first time: severe Covid-19 can result in prolonged impairment of oxygen uptake in the lungs even after four months. Long-term monitoring and treatment of these patients is urgent and important.

Wastewater treatment plants retain 96 percent of mercury
Wastewater treatment plants retain 96 percent of mercury
Each year, around 130 kilograms of mercury flow into Swiss wastewater treatment plants, which filter out the lion's share from the waste water. This is shown by a survey of almost thirty wastewater treatment plants conducted by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the Federal Office for the Environment (FOEN).

The wings of a “genetic bird” protect us against viruses
Researchers have demonstrated that every population can protect itself against a broad range of viruses thanks to the two most diverse HLA immune genes in humans. Do populations from different geographic regions have the same potential for defending themselves against pathogens and against viruses in particular? An analysis of human genomes, especially the HLA genes responsible for the so-called "adaptive" immune system, provide some possible answers to this question.

Neuronal circuits for fine motor skills
Writing, driving a screw or throwing darts are only some of the activities that demand a high level of skill. How the brain masters such exquisite movements has now been described in the journal "Nature" by a team of researchers at the University of Basel and the Friedrich Miescher Institute for Biomedical Research.

Researchers compute turbulence with artificial intelligence
Researchers compute turbulence with artificial intelligence
For the first time, researchers at ETH Zurich have successfully automated the modelling of turbulence. Their project relies on fusing reinforcement learning algorithms with turbulent flow simulations on the CSCS supercomputer "Piz Daint". The modelling and simulation of turbulent flows is crucial for designing cars and heart valves, predicting the weather, and even retracing the birth of a galaxy.
