Satellites reveal speed-up of Antarctic glaciers. On average, the glaciers - giant blocks of moving ice - travel at around 1km a year. But a new study has found a seasonal variation to the speed of the ice flow, which increases by up to 22% in summer when temperatures are warmer. (leeds.ac.uk)

New research has revealed that people with insomnia are 69% more likely to have a heart attack compared to those without sleep disorders during an average nine years of follow-up. by Wagamaga in science

A new study published in the journal Clinical Cardiology has found that individuals who suffer from insomnia are at a higher risk of having a heart attack.

The study revealed that people with insomnia are 69% more likely to have a heart attack compared to those without sleep disorders during an average nine years of follow-up.

The comprehensive review study conducted by a team of experts included a systematic literature review of 1,226 studies comprising data for 1,184,256 adults with an average age of 52.

Among those, 13% had insomnia. During the nine-year follow-up period, 2,406 of those with insomnia experienced heart attacks, as well as 12,398 of those in the non-insomnia category.

The study also found that individuals who sleep five or fewer hours per night have the greatest risk of experiencing a heart attack.

Rupert Murdoch testified that Fox News hosts ‘endorsed’ stolen election narrative. Fox executives say the claims made about Dominion on air were false – part of the voting machine company’s effort to prove the network either knew the statements it aired recklessly disregarded their accuracy by Wagamaga in conspiracy

S.S An unsurprising article which shows how Fox spread misinformation to their gullible viewers.

Newly released court documents reveal that Rupert Murdoch, the billionaire owner of Fox News, acknowledged under oath that several Fox News hosts endorsed Donald Trump’s lie that the 2020 election was stolen from him.

The mogul made the admission during a deposition in the $1.6bn defamation lawsuit brought against the network by the voting machine company Dominion Voting Systems, which has accused Fox News and its parent company, Fox Corporation, of maligning its reputation. In his deposition, Murdoch said that the hosts Maria Bartiromo, Lou Dobbs, Sean Hannity and Jeanine Pirro “endorsed” the false narrative promoted by Trump.

12 exotic bacteria found to passively collect rare earth elements from wastewater. Biosorption of REEs by cyanobacteria is possible even at low concentrations of the metals. The process is also fast: for example, most cerium in solution was biosorbed within five minutes of starting the reaction. by Wagamaga in science

[–]Wagamaga[S] 35 points36 points  (0 children)

Rare earth elements (REEs) are a group of 17 chemically similar metals, which got their name because they typically occur at low concentrations (between 0.5 and 67 parts per million) within the Earth’s crust. Because they are indispensable in modern technology such as light emitting diodes, mobile phones, electromotors, wind turbines, hard disks, cameras, magnets, and low-energy lightbulbs, the demand for them has increased steadily over the past few decades, and is predicted to rise further by 2030.

As a result of their rarity and the demand they are expensive: for example, a kilo of neodymium oxide currently costs approximately €200, while the same amount of terbium oxide costs approximately €3,800. Today, China has a near-monopoly on the mining of REEs, although the discovery of promising new finds (more than one million metric tons) in Kiruna, Sweden was announced with great fanfare in January 2023.

Circular economy

The advantages of moving from a wasteful ‘linear’ economy to a ‘circular’ economy, where all resources are recycled and reused, are obvious. So could we recycle REEs more efficiently, too?

In Frontiers in Bioengineering and Biotechnology, German scientists showed that the answer is yes: the biomass of some exotic photosynthetic cyanobacteria can efficiently absorb REEs from wastewater, for example derived from mining, metallurgy, or the recycling of e-waste. The absorbed REEs can afterwards be washed from the biomass and collected for reuse.

“Here we optimized the conditions of REE uptake by the cyanobacterial biomass, and characterized the most important chemical mechanisms for binding them. These cyanobacteria could be used in future eco-friendly processes for simultaneous REE recovery and treatment of industrial wastewater,” said Dr Thomas Brück, a professor at the Technical University of Munich and the study’s last author.

A recent study published in the journal Sleep suggests that the simple act of wearing an eye mask to block out light while sleeping can improve cognitive function the next day. In two experiments, the researchers found that participants who slept with an eye mask showed enhanced episodic memory encoding and alertness the following day.

As sleep studies continue to demonstrate, good sleep is vital for the healthy functioning of our brains and bodies. For example, too little sleep or a lack of quality sleep can negatively impact our alertness during daily activities. Studies also demonstrate that one driver of disrupted sleep is ambient light.

The sleep-wake cycle is regulated by the earth’s cycle of light and dark, with the morning sunlight signaling us to be alert and the darkness of night signaling us to fall asleep. But sunlight is not the only source of light that can impact our sleep — ambient sources of light like streetlights and light from electronics can also reach our retinas and affect our sleep.

“Moving to the United Kingdom meant not being able to sleep for a simple reason: houses in Cardiff don’t have shutters!” said study author Viviana Greco, a PhD candidate at Cardiff University Brain Research Imaging Centre and freelance associate editor at Researcher. “Most houses in Cardiff area have only curtains and even blackout curtains are not enough to provide complete darkness.”

“This was particularly problematic during the summer months when the sun rises as early as 4am, making it difficult to sleep. As sleep scientists, we understand the importance of getting enough sleep, and waking up at 4am every day was not ideal. We became then curious to know whether wearing an eye mask overnight to block ambient light could be an easy solution!”

Scalable and switchable CO2-responsive membranes. The membrane can be applied to various oil/water systems, including immiscible mixtures, and pollutant-containing emulsions, demonstrating high separation efficiency (>99.9%), recyclability, and self-cleaning performance by Wagamaga in science

Smart membranes with responsive wettability show promise for controllably separating oil/water mixtures, including immiscible oil-water mixtures and surfactant-stabilized oil/water emulsions. However, the membranes are challenged by unsatisfactory external stimuli, inadequate wettability responsiveness, difficulty in scalability and poor self-cleaning performance. Here, we develop a capillary force-driven confinement self-assembling strategy to construct a scalable and stable CO2-responsive membrane for the smart separation of various oil/water systems. In this process, the CO2-responsive copolymer can homogeneously adhere to the membrane surface by manipulating the capillary force, generating a membrane with a large area up to 3600 cm2 and excellent switching wettability between high hydrophobicity/underwater superoleophilicity and superhydrophilicity/underwater superoleophobicity under CO2/N2 stimulation. The membrane can be applied to various oil/water systems, including immiscible mixtures, surfactant-stabilized emulsions, multiphase emulsions and pollutant-containing emulsions, demonstrating high separation efficiency (>99.9%), recyclability, and self-cleaning performance. Due to robust separation properties coupled with the excellent scalability, the membrane shows great implications for smart liquid separation.
