For animals such as fish and insects that can’t control their body temperature, heat waves could be particularly detrimental. “Changes in air temperature will affect brain temperature,” says Baird. A hotter brain could hinder the functioning of nerves, and that, she says, “might affect sensing, memory, and learning.” Cross section shows band of cells in ..

Stanley Plotkin, 93, was instrumental in developing a number of vaccines over the course of his career. He recently said that he’s “beginning to regret having lived so long—because we’re going downhill.” How could we possibly have gotten here? Maybe we’ve always been here. It turns out that the anti-vaccine arguments currently flooding the Internet ..
Grants meet the culture war The document makes clear what sorts of things might be considered administration priorities and national interest—and they’re largely a war on woke. For example, the Trump administration canceled PEPFAR, a program meant to limit the spread of HIV in Africa; it’s a step that is estimated to lead to hundreds ..
The team also found that the immortality of severed tissues is, to the best of our knowledge, unique to P. fabricii. The researchers conducted comparative experiments on explanted tissues from related sea cucumber species, and none showed equivalent tissue survival. Zombie cucumbers Back in 1951, doctors at Johns Hopkins Hospital in Baltimore took a sample ..
Until recently, however, most evidence linking small sperm RNAs to environmental challenges and subsequent effects in offspring has been correlational. Attempts to pin down causality—by injecting RNAs directly into embryos—have often used far higher RNA concentrations than typically found in sperm. In fact, there was no proof that the RNA fragments even make it inside ..
The impact of 63.5 million cubic meters of rock hitting the fjord released forces large enough to be registered globally. The seismic waves that cascaded across the planet were recorded by sensor stations worldwide and were equivalent in energy to a magnitude 5.4 earthquake. The sloshing water within the fjord established a 66-second long-period seiche, ..
Like any other manufactured chip, the wiring that connects the quantum dots is locked into place during the chip’s manufacture. Since different error correction schemes require different connections among the qubits, this forces us to commit to specific error-correction schemes during manufacturing. If a better scheme is developed after a chip is made, it’s probably ..

The actual shipwrecks of the HMS Erebus and the HMS Terror were not found until 2014 and 2016, respectively. Thanks to the cold water temperature, lack of natural light, and the layers of silt covering many of the artifacts, the ship and its contents were in remarkably good condition. Even some of the windowpanes were ..
Pollen isn’t the only allergen impacted by climate change. Increased humidity, heat, and flooding also create ideal conditions for mold to flourish in places where it was previously rare. That can cause mold allergies to flare up, especially in the aftermath of climate-driven disasters like hurricanes, or for patients living in older buildings, basement units, ..
