Ancient Retroviruses Make Up 8% of Human Genome, Researchers Say

Like modern HIV, ancient human endogenous retroviruses (HERVs) had to insert their genetic material into their host’s genome to replicate. Possible sites of HML-2 expression. Image credit: Burn et al., doi: 10.1371/journal.pbio.3001826. Viruses insert their genomes into their hosts in the form of a provirus. There are around 30 different kinds of HERVs in people...

Finnish researchers lay the groundwork for flying drones

A new aerospace research and development (R&D) centre called Lift is the latest in a series of collaborative efforts to help develop drone technology – and a drone industry – in Finland. The project involves a community of experts, and one of the founding members is VTT Technical Research Centre of Finland.   Owned by...

Researchers reveal secret of aye-ayes’ long middle finger | Animals

With its big eyes, bushy tail and sensitive ears, the aye-aye may appear a cute, if quirky, creature. But now researchers have discovered it has a less endearing trait: it uses its long middle finger to pick its nose – and eat the mucus. Aye-ayes are – like humans – primates, but they are nocturnal,...

Pro-China social media campaign sought to influence U.S. voters, researchers say

A sprawling online propaganda campaign that pushes pro-China messaging has been trying to influence American voters, researchers say. Two companies that study large-scale online influence operations published research this week showing that a pro-China campaign was active and targeting the U.S. midterm elections as recently as this month. Researchers found fake accounts across the internet...

Researchers unveil local electronic structure of lanthanide-doped double perovskites

Schematic of electronic structure and luminescence mechanism in Cs2NaInCl6:Ln3+ double perovskites. Credit: Prof. Chen’s group Lead-free halide double perovskites (DPs) have evoked great interest due to their unique optical properties. Recently, lanthanide ion (Ln3+) with rich electronic energy levels have been proposed for tailoring the optical performance of DPs toward the near-infrared (NIR) regions. Among...

Fish feed additive banned in EU found in Tasmanian salmon at concerning levels, researchers say | Environment

A fish feed additive banned in the European Union out of concerns for health impacts in animals and humans has been found in Tasmanian salmon at concerning levels, say experts who are calling for tighter regulations. Dr Christian Narkowicz, an organic chemist, last year commissioned the National Measurement Institute to test salmon for residues of...

Researchers Use Quantum ‘Telepathy’ to Win an ‘Impossible’ Game

To win at the card game of bridge, which is played between two sets of partners, one player must somehow signal to their teammate the strength of the hand they hold. Telepathy would come in handy here. But telepathy isn’t real, right? That’s correct. For decades, however, physicists have suspected that if bridge were played...

With scanning ultrafast electron microscopy, researchers unveil hot photocarrier transport properties of cubic boron

Credit: Matter (2022). DOI: 10.1016/j.matt.2022.09.029 In a study that confirms its promise as the next-generation semiconductor material, UC Santa Barbara researchers have directly visualized the photocarrier transport properties of cubic boron arsenide single crystals. “We were able to visualize how the charge moves in our sample,” said Bolin Liao, an assistant professor of mechanical engineering...
