Non-Hermitian geometry reveals when quantum amplification depends only on start and end points

In quantum mechanics, the geometry of quantum states has emerged as a powerful framework for understanding phenomena ranging from electrical conductivity to superconductivity. One research direction aims to extend these geometric concepts to non-Hermitian quantum mechanics—where systems can exchange energy with their environment—including the generalization of the Berry phase, a key geometric quantity, to the non-Hermitian case.

However, many geometric properties unique to non-Hermitian quantum mechanics remain poorly understood.

“We knew geometry played a central role in ordinary quantum mechanics, but what genuinely new geometric effects might emerge in the non-Hermitian case was far from clear,” explains Tomoki Ozawa, a theoretical physicist at AIMR. “We wanted to identify geometric phenomena that are truly intrinsic to non-Hermitian quantum mechanics.”

New oral heart failure drug appears to be safe and well tolerated in 58-patient early clinical trial

An early clinical study shows that a new oral drug is safe and well tolerated in patients with chronic heart failure. The study, led by researchers at Karolinska Institutet, has been published in The Lancet.

Heart failure with reduced pumping capacity means that the heart struggles to pump blood effectively around the body. Despite current treatments, many patients’ conditions worsen over time, and existing drugs that strengthen the heart’s contractions can cause serious side effects, such as heart rhythm disturbances and effects on blood pressure.

In the study, researchers investigated a new drug, AC01, which targets the body’s ghrelin receptor. Ghrelin is a hormone that influences metabolism and growth hormone release, and its receptor is also found in heart muscle. AC01 is intended to strengthen the heart’s pumping ability through a different biological mechanism from traditional heart-stimulating drugs, thereby reducing the risk of side effects.

One of the most popular ideas in physics right now is something named “ER = EPR.” This theory has it that entangled particles are actually linked by tiny, tiny wormholes. Recently, a group of physicists tested the idea – let’s take a look at their findings.

Breastfeeding may protect against ADHD symptoms

A new study from the University of Bergen shows an association between breastfeeding up to 6 months of age and a reduced risk of ADHD symptoms from ages 3 to 8.

Breast milk is the primary source of nutrition for infants. It is uniquely tailored for the child and contains numerous components beneficial for growth and brain development, including long-chain fatty acids, amino acids, antibodies and beneficial bacteria.

“It is well established that psychiatric symptoms and disorders can be influenced by both genetic and environmental factors,” says Berit Skretting Solberg, psychiatrist and researcher at the Department of Biomedicine, University of Bergen, and senior consultant at Betanien Hospital.

First use of precision editing to study human embryo development reveals role of master gene

Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique can be used to alter a single gene in human embryonic cells, enabling the study of very early human development in unparalleled detail. The study is published in the journal Nature.

Wikipedia Co-Founder Has Been Banned from Editing the Site

It’s important to mention that Sanger had started the WikiProject Intellectual Diversity project to reinforce Wikipedia’s original purpose, which was to provide knowledge neutrally and transparently, especially because, in later years, some people have thought that the site leans toward left-wing ideas.

Sanger said that he feels more sorry for Wikipedia because he was trying to fix the site, but it was overrun by bias and censorship. He wrote about the whole thing for The Free Press, but you can read it only if you are willing to pay the subscription fee.

‘Who is going to pay us when we’re replaced by robots?’ The Indian factory workers told to film themselves for AI

As Lalita sat stitching shirts and trousers, the camera recorded everything: the rhythm of her hands guiding cloth through the sewing machine; the precision with which she aligned collars and seams; the speed at which her fingers corrected folds and imperfections; even interactions with colleagues. ‘We found it funny at first, because of how we all looked with that headgear,’ she says.

But the atmosphere on the factory floor soon started to change. Worried that their productivity was being monitored, workers became more conscious of their movements. Conversations that would ordinarily unfold across sewing lines grew quieter. Some paid greater attention to their work, wary that every mistake, pause or distraction could be captured on camera.

What Lalita and her colleagues did not know was that their daily routines were being captured as part of a growing effort by companies in India to collect first-hand data from factory floors, information increasingly valuable in the race to automate industrial work.

First-person recordings of human movements and interactions are called egocentric data and are vital for training robots that might one day replace humans on the production line.

When workers had cameras attached to them, they found it funny at first. But novelty soon turned to concern.

The #1 most-wanted particle in physics is the graviton, a quantum of gravity. If physicists were to prove that gravitons exist, they would unambiguously prove that Einstein’s theory is ultimately wrong and must be replaced by a more complete theory that gives quantum properties to space and time. In a recent paper, a physicist came up with an ingenious experiment that could prove that gravitons do exist. Let’s take a look.

Faster aging in younger generations linked to rise in early-onset cancer

A new study led by researchers at Washington University School of Medicine in St. Louis provides evidence that younger generations are indeed aging faster biologically than their older counterparts. The causes remain under investigation around the world, including global efforts led by research members of Siteman Cancer Center, based at Barnes-Jewish Hospital and WashU Medicine, and Cancer Grand Challenges, a global initiative co-founded by the National Cancer Institute and Cancer Research U.K.; but importantly, the new research links this accelerated aging to an increased risk of early-onset cancers in younger generations. In general, early-onset cancers are those diagnosed at age 55 or younger.

The larger the gap between biological age — that is, how old our bodies appear to be — and chronological age — which is how many years we have actually lived — the higher the cancer risk, according to the researchers. They found that people in more recent birth cohorts had larger age gaps than those in older birth cohorts, which may help explain the rise in early-onset cancer in recent generations.

Their study also identified links between faster aging in particular organ systems and increased risks for certain cancers. For instance, an immune system that appears older than its actual age was associated with early-onset lung cancer. Similarly, fat tissue that appears older than its chronological age was associated with early-onset colorectal cancer.
