Dear olivier hartmanshenn,

Here is your customized Science X Newsletter for week 19:

	Study reveals stark differences in life expectancy across US states over the past century A sweeping new study led by researchers at the Yale School of Public Health (YSPH) reveals striking disparities in life expectancy across U.S. states and the District of Columbia over the past century.
	New quantum theory of gravity brings long-sought 'theory of everything' a crucial step closer At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the goal of generations of physicists, who have struggled to reconcile the incompatibility of two cornerstones of modern physics: quantum field theory and Einstein's theory of gravity.
	ALICE detects the conversion of lead into gold at the Large Hadron Collider In a paper published in Physical Review C, the ALICE collaboration reports measurements that quantify the transmutation of lead into gold in CERN's Large Hadron Collider (LHC).
	Study of a 16th-century Ethiopian monk's account provides insights into ancient Dongola A recent study by researchers Dr. Dorota Dzierzbicka and Dr. Daria Elagina re-examined and translated a rare first-hand account of a 16th-century Ethiopian monk visiting old Dongola, Sudan.
	AI and brain activity reveal how we perceive faces from other racial groups differently University of Toronto Scarborough researchers have harnessed artificial intelligence (AI) and brain activity to shed new light on why we struggle to accurately recognize faces of people from different races.
	Alternative black hole models suggest quantum effects may erase need for singularities Ever since general relativity pointed to the existence of black holes, the scientific community has been wary of one peculiar feature: the singularity at the center—a point, hidden behind the event horizon, where the laws of physics that govern the rest of the universe appear to break down completely. For some time now, researchers have been working on alternative models that are free of singularities.
	A snapshot of relativistic motion: Special relativity made visible When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special theory of relativity. The object then has a different length than when it is at rest, and time passes differently for the object than it does in the laboratory. All this has been repeatedly confirmed in experiments.
	Natural short sleepers have a genetic mutation, finds new study Not everyone needs 8 hours of sleep to function properly. Some people can feel well-rested and show no negative effects of sleep deprivation, even after just 4 hours of sleep, which is likely the result of a genetic mutation.
	A recently-discovered termite terminator is better, more targeted and won't harm humans Drywood termites, the ones that hide in wooden structures, molt about seven times in their lives. UC Riverside researchers have found that a chemical preventing them from growing new exoskeletons will also end their infestation of your home.
	Mass spectrometry method identifies pathogens within minutes instead of days Traditionally, bacterial diseases are diagnosed by the tedious isolation of pathogens and the creation of bacterial cultures. Waiting times of several days are the rule here. Only then can targeted treatment of the disease begin.
	Household drinking water identified as key pathway for bacterial transmission Worldwide, more than 500,000 children under age 5 die each year from gastrointestinal bacterial infections, largely in communities with limited access to safe drinking water, sanitation and hygiene infrastructure. But to alleviate this public health threat, scientists need to better understand how these pathogens spread.
	World's wealthiest 10% have contributed to two-thirds of global warming since 1990, study finds Wealthy individuals have a higher carbon footprint. A new study published in Nature Climate Change quantifies the climate outcomes of these inequalities. It finds that the world's wealthiest 10% are responsible for two-thirds of observed global warming since 1990 and the resulting increases in climate extremes such as heat waves and droughts.
	Private Japanese lunar lander enters orbit around moon ahead of a June touchdown A private lunar lander from Japan is now circling the moon, with just another month to go before it attempts a touchdown.
	Minimally invasive disc injection reduces pain and improves function in chronic back pain, feasibility study finds VIVEX Biologics, Inc. sponsored research reports positive outcomes for patients with chronic lumbar discogenic pain treated using a single intradiscal injection of VIA Disc NP, an allogeneic nucleus pulposus product derived from cadaveric disc tissue.
	Bird flu in cats points to risk of another pandemic It's spring, the birds are migrating and bird flu (H5N1) is rapidly evolving into the possibility of a human pandemic. Researchers from the University of Maryland School of Public Health have published a comprehensive review documenting research on bird flu in cats and calling for urgent surveillance of cats to help avoid human-to-human transmission.
	Origins of language: Wild chimps mirror linguistic structures in human language Humans are the only species on Earth known to use language. They do this by combining sounds into words and words into sentences, creating infinite meanings.
	Physicists discover an unusual chiral quantum state in a topological material Chirality—the property of an object that is distinct from its mirror image—has long captivated scientists across biology, chemistry, and physics. The phenomenon is sometimes called "handedness," because it refers to an object possessing a distinct left- or right-handed form. It is a universal quality that is found across various scales of nature, from molecules and amino acids to the famed double-helix of DNA and the spiraling patterns of snail shells.
	Okra and fenugreek extracts remove most microplastics from water, finds research The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer. Previously, researchers proposed using these sticky natural polymers to clean up water. Now, they report in ACS Omega that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics in ocean water, freshwater and groundwater.
	Shingles vaccine lowers the risk of heart disease for up to eight years, study finds People who are given a vaccine for shingles have a 23% lower risk of cardiovascular events, including stroke, heart failure, and coronary heart disease, according to a study of more than a million people published in the European Heart Journal.
	Nanoplastics generated from real-world plastic waste readily adsorb heavy metal ions, study reveals Some 460 million metric tons of plastic are produced globally each year, out of which a staggering 91% of plastic waste is never recycled—with 12% incinerated and 79% left to end up in landfills and oceans and linger in our environment.
