During the pandemic, I have gone from uttering a few words of encouragement to myself to full-blown arguments. I’m not the only one. I asked psychologists what purpose this serves“We should probably go out now,” I say to Danny as I vegetate in front of the TV. “Yeah, we should, but I can’t be arsed,” Danny replies, sitting in an identical pose. “C’mon, we need the exercise; can’t...

Deep Time project investigated how a lack of external contact would affect sense of time – and two thirds wanted to stay longerFifteen people have emerged from a cave in south-west France after 40 days underground in an experiment to see how the absence of clocks, daylight and external communications would affect their sense of time.With big smiles on their pale faces, they left their voluntary...
Companies may seek to dismantle prejudice among their employees – but psychologists question whether these courses effect lasting changeHere’s a fact that cannot be disputed: if your name is James or Emily, you will find it easier to get a job than someone called Tariq or Adeola. Between November 2016 and December 2017, researchers sent out fake CVs and cover letters for 3,200 positions....
Celestial event due to take place shortly before sunset on Tuesday and will be visible until next morningA pink supermoon is set to brighten the night skies over the UK next week, though there will not be any noticeable difference in colour, as the name might suggest.The full moon in April is also known as the “pink moon” as it is named after pink flowers, known as phlox, which bloom in the...
Marine archaeologist unearths evidence suggesting biblical king’s riches were based on voyages he funded with Phoenician alliesKing Solomon is venerated in Judaism and Christianity for his wisdom and in Islam as a prophet, but the fabled ruler is one of the Bible’s great unsolved mysteries.Archaeologists have struggled in vain to find conclusive proof that he actually existed. With no...
The government has hit both its self-imposed targets so far. How will it go the rest of the way?More than half of the UK population has now received at least a first dose of vaccine against Covid-19. By Friday evening 33,388,637 people had received one of the Pfizer, AstraZeneca or Moderna vaccines. Here’s how it was done, and what is still left to do. Continue...
Malaria has still not been eradicated in the poorest countries, but that could be about to changeAnother vaccine from Oxford’s Jenner Institute and one that may have a greater impact than that against Covid-19. Results from trials of its malaria vaccine, R21, show it to be 77% effective. If replicated in larger scale trials, it would be a remarkable breakthrough. Malaria kills more than 400,000...

Researchers have developed the first LiDAR-based augmented reality head-up display for use in vehicles. Tests on a prototype version of the technology suggest that it could improve road safety by 'seeing through' objects to alert of potential hazards without distracting the driver.
The team identified a fundamental pattern in the work of the human proteins and determined the structure of their complex with a functional fragment of the papillomavirus oncoprotein. Using these data, the team suggested a way to affect the stability of the studied protein complex, which could be further developed into a therapeutic approach against papillomavirus infections.
Hazelnut is widely grown for its rich oleic acid content and flavor. However, owing to the unavailability of high-quality genetic resources for hazelnut, crop improvement has remained a significant challenge. A new study published in Horticulture Research presents a high-quality whole genome analysis of Chinese hazelnut, along with identification of several genes underlying economically important...
Scientists at Tokyo Institute of Technology (Tokyo Tech) have pioneered a novel method for producing supramolecular protein assemblies from protein crystals. Their approach involves strategically introducing mutations in a protein monomer to create disulfide bonds (S-S) between the building blocks of protein crystals at very specific sites. After isolating the protein crystals from the cells and...
New research suggests efforts to rewild a landscape must take geography and geology into account--an approach that could be applied globally to help conservation biologists save wild ecosystems. The results will be presented at the European Geosciences Union (EGU) General Assembly 2021, which is taking place from 19-30 April 2021.
Researchers using a new method involving the mineral barite have dated the first emergence of continental crust to 500 million years earlier than previously thought. The results will be presented at the European Geosciences Union (EGU) General Assembly 2021, which is taking place from 19-30 April 2021.
Researchers investigated the high-loss free space high-precision time-frequency dissemination experiment between remote locations, simulating the high-precision time-frequency high-orbit satellite-ground links in the channel loss, atmospheric noise, and transmission delay effects.
The discovery is a step forward towards the creation of smart drugs that will neutralize the proteins and prevent disease, without the use of antibiotics
Researchers in Japan have established sustainable cell lines in a coral - a success which could prove to be a pivotal moment for gaining a deeper understanding of the biology of these vital marine creatures. Seven out of eight cell cultures, seeded from the stony coral, Acropora tenuis, have continuously proliferated for over 10 months. The results were published in Marine Biotechnology on the...
