Your 3am Wake-Ups Might Have an Ancient Scientific Explanation
NEWS | 03 August 2026
(TrueCreatives/Canva)But what if this period of wakefulness isn't a malfunction – it's part of an ancient human sleep habit? Sleep runs in cycles of roughly 90 to 110 minutes, moving through light sleep, deep sleep, and rapid eye movement (REM) sleep. It only becomes a problem when the awakening drags on, or when it starts arriving at the same time, night after night. It could just be your circadian rhythm doing what it always does, waking or not, while your cortisol rises steadily anyway. In the meantime, rest assured that if you're awake and worrying at 3 am, you're certainly not alone, and there are a lot of biological reasons behind your wakefulness.

Sponge Foraging in Dolphins Does Something Unique to Their Genes
NEWS | 03 August 2026
It's a tricky task to learn because the sponge messes with the dolphins' echolocation abilities. The team examined nearly 30,000 sites across the dolphins' genomes where DNA methylation – a common epigenetic modification – can occur. DNA methylation acts like a dimmer control rather than an on-off switch. Scientists have traditionally thought that epigenetic changes switch genes either "on" or "off", but research shows those changes can also 'dial down' gene expression in a graded way. But research in roundworms suggests that epigenetic changes can also be inherited, transferred from one generation to the next.

Monday Microscope Mystery: What Is This Black-And-White Vista?
NEWS | 03 August 2026
True compound eyes, built from thousands of individual lenses called ommatidia, belong to insects, crustaceans, and some myriapods. Mites don't have them. When mites have eyes at all, they're simple eyes called ocelli – single-lensed structures, usually arranged in one to three pairs. And plenty of mites don't bother with eyes. This image was captured with a scanning electron microscope, which fires a beam of electrons at the sample rather than light, producing a super-detailed black-and-white image.

Unexpected Structure Detected in The Brains Of Humans And Mice With Alzheimer's Disease
NEWS | 03 August 2026
Alzheimer's disease is the most common form of dementia, which affects approximately 57 million people globally – a number that's projected to rise to more than 150 million by 2050. "This discovery identifies mitochondrial plaques as a previously unrecognized feature of Alzheimer's disease," says biochemist Paul Robbins from the University of Minnesota. Previous, indirect measurements in mice engineered with mutations to induce symptoms of Alzheimer's disease offered only "limited insight" due to inadequate sensitivity. "By understanding how these plaques form and contribute to disease progression, we may be able to develop new strategies to slow or even prevent Alzheimer's disease," says Robbins. As the researchers conclude, "combination treatments targeting both amyloid-beta plaques and mitochondrial plaques to address the mixed plaques hold great promise to provide better therapeutic outcomes in Alzheimer's disease."

There Might Be a Way to Observe Dark Matter Decaying Into Gravity Particles
NEWS | 03 August 2026
The rest is composed of unseen dark matter, which only interacts with gravity and seems essential for anchoring major celestial structures like galaxies and clusters of galaxies. Current attempts to detect dark matter, whatever it may be, include using vats of super-cold liquid xenon or probing the glowing heart of the Milky Way for explosively self-annihilating particles. Instead of seeking, say, exploding dark matter, researchers say that perhaps we should search for the signs of dark matter transforming into even more esoteric particles, such as the hypothetical gravitons that may imbue the Universe with gravity. As detailed in a paper published in the journal Physical Review D, a team of physicists suggests searching for the indirect signs of dark matter decaying into gravitational particles, which themselves may then transform into particles of light. (Dunsky et al., Physical Review D, 2026)Filaments also exhibit expansive magnetic fields that remain coherent, or uniform, across millions of light-years.

The Brain Seems to Rearrange Itself as Tinnitus Becomes Chronic
NEWS | 03 August 2026
While the phantom sound is thought to begin in the auditory system, the findings suggest that long-term tinnitus may eventually involve widespread changes across the brain. To learn more about the brain changes associated with long-term tinnitus, the researchers recruited people who have the condition, but no apparent hearing loss. The reason was simple: They wanted to isolate the brain changes associated with tinnitus itself. The two tinnitus groups showed striking differences, suggesting that patterns of brain activity change as tinnitus becomes chronic. Future longitudinal studies, they say, should track patients from onset to the chronic stage to see whether an individual's brain changes over time.

Scientists Tested 17 Human Artery Samples – And Found Microplastics in Every Single One
NEWS | 03 August 2026
Looking at 17 human arterial samples collected during surgical procedures, the researchers found microplastics present in all of the samples – and at concentrations relatively higher than those for plastics in blood. "We found that three types of arterial samples including coronary, carotid, and aortic arteries contained microplastics," write the researchers in their published paper. Arteries containing dangerous fatty plaques (the coronary and carotid artery samples) had around twice the level of microplastics than those without (the aortic artery samples) the researchers found – potential evidence linking microplastics to cardiovascular disease. "The proportion of microplastics in arterial samples may be related to the frequency of human exposure to these microplastics, which deserves further investigation," write the researchers. "This study provides valuable data for further hazard assessments of microplastics on human cardiovascular health," write the researchers.

There May Be 170 Million Black Holes Lurking in The Milky Way's Graveyard
NEWS | 03 August 2026
That makes it hard to know exactly how many invisible stellar-mass black holes our galaxy contains. Now, astronomers have simulated the Milky Way to find its hidden "Galactic Underworld", estimating that around 170 million stellar-mass black holes are scattered throughout our galaxy. Using what we know about how stars, black holes, and galaxies evolve, scientists can simulate the Milky Way over its 13.6-billion-year history. Spread across the Milky Way's 13.6-billion-year history, 170 million black holes works out to an average of roughly one new stellar-mass black hole every 80 years. Heavier black holes, by contrast, form with more material falling back onto the black hole, damping the kick.

Earth's Inner Core Could Be Full Of Extreme Hydrogen Unlike Anything on The Surface
NEWS | 03 August 2026
The first is the hexagonal close-packed (HCP) arrangement:Earth's inner core might be composed of a hexagonal close-packed (HCP) phase of iron. In terms of total hydrogen, a radial concentration gradient seems to exist in the inner core, with the hydrogen composition "dropping sharply" while crossing the boundary from Earth's outer core and traveling toward the center of the inner core. (Wu et al., PNAS, 2026)This radial hydrogen gradient may drive superionic hydrogen toward the inner core boundary, where it loses its superionic status and re-partitions into a liquid mix to enrich the outer core. This result suggests that the hydrogen exchange between the inner and outer core is not limited to the direct partitioning that occurs as the inner core crystallizes. The exchange also occurs via a continuous redistribution of superionic hydrogen, with the inner core continuing to grow at a rate of 1 millimeter per year.

Are Artificial Sweeteners Really Worse For Your Brain Than Sugar? An Epidemiologist Explains
NEWS | 03 August 2026
The headlines have been claiming for months that artificial sweeteners speed up cognitive decline. "This is all made especially remarkable given that it doesn't really show any issues from artificial sweeteners at all." – epidemiologist Gideon Meyerowitz-KatzThis is all made especially remarkable given that it doesn't really show any issues from artificial sweeteners at all. Despite decades of fearmongering when it comes to artificial sweeteners, the reality is that they are very well-tested and generally not harmful. Artificial sweeteners get a bad rap, but the data show quite convincingly that they are, at least, better for you than sugar.

'Most Isolated Environments': Microplastics Are Finding Their Way Down to Deep-Sea Hydrothermal Vents
NEWS | 03 August 2026
Our planet clearly has a microplastics problem: These tiny synthetic fragments are finding their way into ancient rocks, human bones, and almost every species of animal on Earth. Researchers led by a team from the Korea Research Institute of Bioscience and Biotechnology (KRIBB) have found microplastics in snails and mussels living around deep-sea hydrothermal vents. "Plastic pollution has now spread even to deep-sea hydrothermal vent ecosystems that were once considered among the most isolated environments on Earth," says marine biologist Se-Joo Kim, from KRIBB. The snails and mussels in the Indian Ocean had significantly higher concentrations of microplastics in their bodies than those in the southwestern Pacific. The research has been published in Water Research.

Hell-World Venus May Have Once Had Oceans Across 90% of Its Hot, Dry Surface
NEWS | 03 August 2026
Most of the available data today comes from NASA's Magellan probe, which spent several years in the early 1990s using radar to map Venus's surface from planetary orbit. Those images revealed a rugged landscape shaped by volcanism – that Venus is a volcanic world is without question, with over 85,000 volcanic features identified to date. What Ghail and his colleagues wondered was whether some of those putatively volcanic features might actually be marine in origin. The researchers estimate water may once have covered around 90 percent of Venus's surface, holding roughly 40 percent as much water as Earth's oceans. The researchers posit that many of these channels instead resemble submarine channels on Earth, carved by dense currents flowing beneath the ocean's surface.

New Evidence That Microplastics Can Cross Placental Barrier And Alter Hormone Production
NEWS | 03 August 2026
But whether the presence of plastic particles actually disrupts human fetal development remains unknown. Meanwhile, "existing human placental in vitro models do not fully capture the complex maternal-fetal interactions in steroidogenesis and structural arrangement," the authors write. So, they developed a 'petri dish' model made from three layers of different kinds of living human cells. Endocrinol., 2026)Fluorescence microscopy revealed there were more of these plastic particles embedded throughout the first two cell layers, though not the H295R cells.
