Here is your customized Science X Newsletter for week 29:

	Clinical trial shows taking blood pressure medication at night improves nocturnal and daytime control Research led by Sichuan University in China has revealed that bedtime antihypertensive medication dosing improves nocturnal blood pressure control over morning dosing in patients with hypertension.
	Scientists achieve first experimental observation of the transverse Thomson effect In a new Nature Physics paper, researchers report the first experimental observation of the transverse Thomson effect, a key thermoelectric phenomenon that has eluded scientists since it was predicted over a century ago.
	Neanderthal gene variant lowers muscle enzyme activity in modern humans The enzyme AMPD1 plays a key role in muscle energy production and normal muscular function. Loss of AMPD1 activity due to genetic mutations is the most common cause of metabolic myopathy in Europeans, occurring at a frequency of 9% to 14%.
	Psychologists introduce third path to 'good life'—one full of curiosity and challenge New research suggests that psychological richness—a life of perspective-changing experiences—may matter just as much as happiness or meaning.
	Robots now grow and repair themselves by consuming parts from other machines Today's robots are stuck—their bodies are usually closed systems that can neither grow nor self-repair, nor adapt to their environment. Now, scientists at Columbia University have developed robots that can physically "grow," "heal," and improve themselves by integrating material from their environment or from other robots.
	Higher anticholinergic use linked to faster decline in mobility and strength Kaiser Permanente Washington scientists report that higher cumulative anticholinergic exposure predicted a faster decline in gait speed and grip strength among older adults.
	Mammals have evolved into ant eaters 12 times since the dinosaur age, study finds Mammals have developed some unusual eating habits over the past 100 million years, but a new study has uncovered the surprising lengths to which some have gone to satisfy one of the more peculiar—a taste for ants and termites.
	Childhood trauma shapes adult stress appraisal and mental health outcomes, research reveals University of Leeds psychologists report that stress appraisal and perceived stress act as key conduits linking childhood trauma to adult depression, anxiety, defeat, and entrapment.
	Rethinking the Big Bang: Gravity and quantum ripples may explain cosmic origins A team of scientists led by expert Raúl Jiménez, ICREA researcher at the University of Barcelona's Institute of Cosmos Sciences (ICCUB), in collaboration with the University of Padua (Italy), has presented a revolutionary theory about the origins of the universe. The study, published in the journal Physical Review Research, introduces a radical change in the understanding of the first moments after the Big Bang, without relying on the speculative assumptions that physicists have traditionally assumed.
	New study links human ribcage shape to climate Ötzi the Iceman may have come to an unfortunate end while crossing the Alps more than 5,000 years ago, but thanks to his well-preserved remains, he's still helping us understand our past. A new digital reconstruction of the mummy's ribcage is providing fresh insights into modern human evolution.
	First electronic–photonic quantum chip created in commercial foundry In a milestone for scalable quantum technologies, scientists from Boston University, UC Berkeley, and Northwestern University have reported the world's first electronic–photonic–quantum system on a chip, according to a study published in Nature Electronics.
	Higher copper intake correlates with better cognitive performance in older adults, data suggest Cognitive impairment is increasing globally. All stages of dementia are marked by declines in memory and executive function. Previous research has examined whether micronutrient levels may relate to cognitive resilience.
	Obesity more likely caused by high calorie diet than lack of exercise It's common knowledge that obesity is a global epidemic, particularly in industrialized countries, and that it is a major cause of disease and poor overall health. However, there has been a tug-of-war in the debate of whether the main cause of obesity is diet or a lack of exercise.
	'Large' furry creatures found in Mexico rain forest in first-of-its-kind sighting Along the banks of the Lacantún River, a hollow tree hid two creatures never before reported in Mexico.
	Blades of light: A tabletop method for generating megatesla magnetic fields Researchers at The University of Osaka have developed a novel method for generating ultra-high magnetic fields via laser-driven implosions of blade-structured microtubes. This method achieves field strengths approaching one megatesla—a breakthrough in compact, high-field plasma science.
	The dark side of time: Scientists develop nuclear clock method to detect dark matter using thorium-229 For nearly a century, scientists around the world have been searching for dark matter—an invisible substance believed to make up about 80% of the universe's mass and needed to explain a variety of physical phenomena. Numerous methods have been used in attempts to detect dark matter, from trying to produce it in particle accelerators to searching for cosmic radiation that it might emit in space.
	Nearly a billion people will be affected by a scarcity of water by 2100, researchers say In an analysis of the best available Earth systems models, Northeastern researchers found that by the turn of the next century, 850 million people will feel the effects of declining runoff from the world's major rivers.
	New study tackles dynamics of common—and difficult—sailing maneuver Tacking—a maneuver used to sail a boat against the wind, changing direction in a zig-zag fashion—is one of the most difficult but necessary sailing maneuvers. While tacking is common, the movement of the sails and wind forces during the turn are not well understood.
	White shark spotted 40 feet off Cape Cod beach Phones with the Sharktivity app were buzzing on the regular for the first time this season on July 15.
	Scientists unravel how a tiny region of the brain helps us form distinct memories Life may unfold as a continuous stream, but our memories tell a different story. We do not recall the past as one long, unbroken text. Instead, we remember it as a series of meaningful events, like how sentences are structured with grammar and punctuation. Like any narrative, this organization gives our experiences shape and coherence, helping us make sense of what and when things happen.
