Neuroscientists from around the world have worked in parallel to map, for the first time, the entire brain activity of mice while they were making decisions. This achievement involved using electrodes inserted inside the brain to simultaneously record the activity of more than half a million neurons distributed across 95 percent of the rodents’ brain volume.

Thanks to the image obtained, the researchers were able to confirm an already theorized architecture of thought: that there is no single region exclusively in charge of decisionmaking and instead it is a coordinated process among multiple brain areas.

Ice formation on propeller blades or aircraft wings can cause major problems. It can limit flight time, increase costs and pose safety and environmental risks.
That is why researchers at SINTEF have developed a new coating material that makes ice removal both more efficient and cheaper—without harming the environment.

Today, ice is usually removed using electrical heating, either with permanent heating systems in the rotor blades, or by temporarily applying chemical de-icing agents. The challenge is that these methods do not provide sufficient protection against the formation of new ice. As a result, they have to be repeated several times, leading to high maintenance costs.

The industry is therefore eyeing the new anti-icing method that SINTEF is developing, according to researcher Christian Karl, who is part of the research team on the project called IceMan. "This is a more effective and long-lasting method for removing ice on technical surfaces. We're seeing that more and more industrial sectors, like wind energy, aerospace, automotive and marine technology, have turned their attention to our solution."

The coating is based on polyurethane, a type of polymer material, and can be sprayed or brushed directly onto the surfaces, giving them ice-repellent properties and slowing down ice formation. The study is published in the Journal of Nanoparticle Research.

"In practice, this will mean that supercooled water droplets that land on the rotor blades won't be able to freeze onto the surface. The water will bead up and roll off the surface before it has time to freeze. If, contrary to expectations, it remains there, it will adhere less well and be easier to remove," says the SINTEF researcher.

Research colleague Monika Pilz led the project. She says that the additives are environmentally friendly and are made in such a way that they can easily be scaled up and used in industry settings.

Scientists have used a gravitational wave detector to "hear" two black holes getting bigger as they merged into a single, gigantic entity.

The detection, made by the Laser Interferometer Gravitational-wave Observatory (LIGO) on Jan. 14, provides the best evidence yet for a theory put forth by famed physicist Stephen Hawking more than half a century ago, but which was never proven in his lifetime.

Now with a decade of experience under their belts, LIGO collaborators have made many improvements to the detectors — such that black hole mergers are now spotted about once every three days instead of once a month, according to a statement from Caltech, which jointly operates LIGO along with MIT.

During the event detected Jan. 14, LIGO witnessed two black holes merging, with the resulting black hole measuring significantly bigger than the two objects entering into the collision.

Before the merger, the combined surface area of the two black holes was about 93,700 square miles (243,000 square kilometers) — roughly the size of Oregon. After the merger, by contrast, the newly formed and single black hole had a surface area of roughly 154,500 square miles (400,000 square km) — about the size of California. In other words, the newly merged black hole was larger than the sum of its parts.

The Atlas blue butterfly, also known as Polyommatus atlantica, has been genetically confirmed as having the highest number of chromosomes out of all multicellular animals in the world.

This insect boasts 229 pairs of chromosomes, while many of its close relatives have only 23 or 24 pairs. Researchers at the Wellcome Sanger Institute and the Institute of Evolutionary Biology (IBE: CSIC-UPF), Barcelona, have revealed that these chromosomes have been broken up over time, instead of duplicated.

The first genomic study of this butterfly, published in Current Biology, allows experts to begin to explore the evolutionary reasons behind this extreme number of chromosomes.

Chromosome changes are also seen in human cancer cells, and therefore, understanding this process in different species could help inform cancer research.

This is the first time that the Atlas blue butterfly has been sequenced. From this, experts have produced a gold-standard reference genome for this species, allowing researchers to compare this extreme genome to other butterflies and moths to understand more about how species form and change over time.

Evolution and the development of new species happen over millions of years, making it hard to study practically. Instead, experts can use the DNA of a species and compare this to others in the same family to understand which genes and traits have been kept and which have been lost and then make informed guesses as to why.

Cells bumping against one another use electricity to identify which of their neighbors has the least energy to expel them. The King's College London study in partnership with the Francis Crick Institute provides insight into diseases including cancer and stroke, where cellular energy levels can be disrupted, preventing the maintenance of healthy cell numbers.

Epithelial cells, which line all organs in the body, turnover rapidly to maintain a tightly packed protective layer. They undergo a process called extrusion to eliminate excess or damaged cells, essential for balancing cell division and cell death.
Extrusion is a fundamental process, common in living organisms from sea sponge to humans, that drives most epithelial cell death. When it goes wrong and the balance of healthy cells is disrupted, it can lead to disease.

Earlier work by the group led by Professor Jody Rosenblatt at King's College London discovered that extrusion is mechanical—when too many epithelial cells accumulate, crowding triggers some to be physically squeezed out, causing them to die.

The scientists were unsure if the crowded cells selected to extrude were randomly selected, or some were specifically targeted. This latest discovery, published in Nature, reveals that crowding selectively targets the weakest, energy-poor cells for death.

Epithelial cells spend a remarkable amount of energy establishing and maintaining an electrically charged surface or membrane. While this electrical potential is well known in nerve cells, its role in other cell types has been largely overlooked.

Crispr gene-editing technology has demonstrated its revolutionary potential in recent years: It has been used to treat rare diseases, to adapt crops to withstand the extremes of climate change, or even to change the color of a spider’s web. But the greatest hope is that this technology will help find a cure for a global disease, such as diabetes. A new study points in that direction.

For the first time, researchers succeeded in implanting Crispr-edited pancreatic cells in a man with type 1 diabetes, an autoimmune disease where the immune system attacks insulin-producing cells in the pancreas. Without insulin, the body is then unable to regulate blood sugar. If steps aren’t taken to manage glucose levels by other means (typically, by injecting insulin), this can lead to damage to the nerves and organs—particularly the heart, kidneys, and eyes. Roughly 9.5 million people worldwide have type 1 diabetes.

In this experiment, edited cells produced insulin for months after being implanted, without the need for the recipient to take any immunosuppressive drugs to stop their body attacking the cells. The Crispr technology allowed the researchers to endow the genetically modified cells with camouflage to evade detection.

Researchers have developed a tiny device that extinguishes one of the biggest heat sources in quantum computers, cutting their running costs and potentially bringing these machines closer to commercial reality.

Most quantum computers operate at temperatures close to absolute zero (459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius) using specialized cooling equipment to maintain the delicate quantum states of qubits — the core processing units of quantum systems.

Cryogenic amplifiers are also used in quantum computers to boost the extremely weak signals qubits emit at these ultra-low temperatures. This makes it possible to accurately measure their quantum states — which is needed in order to understand what the quantum computer is actually doing.

The challenge with existing amplifiers used to measure qubit behaviour — or any electronics used in quantum computers, for that matter — is that they generate heat. This means the quantum systems require additional cooling systems that add bulk and cost, both of which present major barriers to making quantum systems practical and scalable.

Now, Qubic, a Canadian startup, has devised a cryogenic traveling-wave parametric amplifier (TWPA) made from unspecified "quantum materials" that enables an amplifier to operate with virtually zero heat loss, representatives from the company said in a statement.

They added that this device reduced thermal output by a factor of 10,000 — down to practically zero.

Developed over more than a decade at the University of the Sunshine Coast (UniSC) as part of a global collaborative effort, the vaccine is designed to protect the tree huggers from chlamydia, a bacterial infection that’s been devastating their populations for decades. Chlamydia spreads rapidly among wild populations, causing painful urinary tract infections, infertility, blindness, and even death. But now, a breakthrough single-dose vaccine could turn the tide for the species.

📡Discovery of Protoplanetary Disk Caught in Explosion Driven by Stellar Jet. 🤯
This finding suggests that the disk, which serves as a seedbed for planets, is exposed to a harsher environment than previously thought.

Looking like a cosmic double-bladed lightsaber, Webb captured enormous jets of gas 8 light-years across erupting from a massive baby star. This rare sighting is helping us better understand how massive stars form.

What IS a "potential biosignature" anyway? For a complete review and deep dive into the recent announcement, check out this special edition of the Mars Report:

Magnetic fields that originated during the earliest moments of the Universe may have been billions of times weaker than the pull of a household fridge magnet, with strengths on the scale of the magnetism produced by neurons in the human brain. Despite being so faint, measurable evidence of these fields can still be detected in the cosmic web, the vast network of structures linking galaxies across the Universe.

This conclusion comes from a study involving about 250,000 computer simulations carried out by researchers at SISSA (the International School for Advanced Studies in Trieste) in collaboration with teams from the Universities of Hertfordshire, Cambridge, Nottingham, Stanford, and Potsdam.

Vitamin D supplements may help safeguard the protective caps on our chromosomes that influence the pace of aging, raising hopes that the “sunshine vitamin” could support healthier longevity, according to a recent study.

Researchers reported that taking 2,000 IU (international units, a standard vitamin measurement) of vitamin D each day helped preserve telomeres, the small structures at the ends of chromosomes that act like the plastic tips of shoelaces, shielding DNA from damage during cell division.

Each of our 46 chromosomes ends with a telomere, which gradually shortens every time a cell divides. Once telomeres become critically short, cells lose the ability to divide and ultimately die.

Shortened telomeres have been associated with several major age-related conditions, including cancer, heart disease, and osteoarthritis. Factors such as smoking, chronic stress, and depression appear to accelerate this process, while inflammatory processes in the body also contribute to telomere loss.
