Photos   A rare and bewildering intermediate between crystal and glass can be the most stable arrangement for some combinations of atoms, according to a study from the University of Michigan.   The findings come from the first quantum-mechanical simulations of quasicrystals—a type of solid that scientists once thought couldn't exist. While the atoms in quasicrystals are arranged in a lattice, as in a crystal, the pattern of atoms doesn't repeat like it does in conventional crystals. The new simulation method suggests quasicrystals—like crystals—are fundamentally ...

(WASHINGTON, June 13, 2025) – Women with breast cancer who were also carriers of the BRCA1 or BRCA2 mutation and received textured breast implants as part of their reconstructive surgery after mastectomy were 16 times more likely to develop breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), a rare T-cell lymphoma, compared with similar women without these genetic mutations, according to a study published today in Blood Advances. “Our findings show that BRCA1 and BRCA2 mutations are a significant risk factor for developing this type of lymphoma, confirming earlier suggestions of a possible role. It’s possible ...

Tsunamis and earthquakes pose devastating threats to coastal communities worldwide. However, beyond the immediate destructive power of these events, the negative impact of the disaster waste they produce is sometimes overlooked. For example, when the 2011 Great East Japan Earthquake struck, approximately 23 million tons of waste were generated, severely hindering post-disaster recovery processes. Similarly, the 2024 Noto Peninsula Earthquake produced 2.7 million tons of waste—equivalent to seven years of normal waste disposal. Thus, rapid processing of disaster waste is essential for restoring community functionality, making it a critical ...

Study suggests that appetite for bushmeat – rather than black market for scales to use in traditional Chinese medicine – may be driving West Africa’s illegal hunting of one of the world’s most threatened mammals.   Interviews with hundreds of hunters show pangolins overwhelmingly caught for food, with majority of scales thrown away. Survey work shows pangolin is considered the most palatable meat in the region. The vast majority of pangolin hunting in African ...

Even the best products won’t meet expectations if they are packed poorly — packaging matters. The same goes for drug delivery. Osaka Metropolitan University researchers have uncovered the critical role played by solvents in how effectively drugs can be loaded into metal–organic frameworks (MOFs), a promising class of drug carriers. Their findings shed light on a previously overlooked part of the loading process, with the potential to boost the efficiency of how medications are delivered inside the body. To treat diseases effectively, it’s not just the medicine that counts — but also how that medicine is delivered into our ...

Among the tens of thousands of ant species, incredible ‘intelligent’ behaviors like crop culture, animal husbandry, surgery, ‘piracy’, social distancing, and complex architecture have evolved. Yet at first sight, the brain of an ant seems hardly capable of such feats: it is about the size of a poppy seed, with only 0.25m to 1m neurons, compared to 86bn for humans. Now, researchers from Israel and Switzerland have shown how ‘swarm intelligence’ resembling advance planning can nevertheless emerge from the concerted operation of many of ...

Vaccinated patients hospitalized with COVID-19 who developed acute kidney injury had better outcomes than unvaccinated patients with the same condition, new research suggests. The study found vaccinated patients were less likely to stay on dialysis after discharge, and more likely to survive, than unvaccinated patients. Acute kidney injury, or AKI, is common among people infected with COVID-19, with rates running as high at 46%. It can lead to a mild decrease in kidney function or, if severe enough, to dialysis. The long-term renal and survival outcomes of these patients, however, has not been ...

New research from Adelaide Business School at the University of Adelaide provides a framework for understanding the growing consumer interest in no, low and mid (NLM) alcohol wines. Dr Hannah Ford’s comprehensive scoping review, published in Journal of Marketing Management , suggests that consumer adoption of NLM wines is influenced by a range of factors, while wine businesses themselves play a pivotal role. “The global wine industry is evolving rapidly in response to growing health-conscious and moderation-driven drinking trends,” Dr Ford explains. “The review proposes that appeal to NLM wines is influenced ...

Aichi, Japan--Researchers from the Institute for Molecular Science (IMS)/SOKENDAI and Kyushu University have uncovered the molecular mechanism that drives the "ticking" of the circadian clock in cyanobacteria. Their study reveals how a clock protein called KaiC controls chemical reactions with remarkable precision, acting like the hand of a clock that waits, then moves at just the right moment. The findings were published in PNAS Nexus on April 28, 2025. To adapt to Earth's daily rotation, most living organisms, from simple, single-celled bacteria to complex, multicellular ...

A surgeon can excise breast cancer from the body, but even the most skilled scalpel may not be able to remove every cell — especially when the cells have spread from the original disease site elsewhere in the body. This proliferation and migration of breast cancer cells involves many still unknown molecular means, but researchers at Hiroshima University have elucidated at least one mechanism. With the discovery, they may have also uncovered how short chains of protein building blocks could serve as a novel anticancer drug.  The team published their findings on April 9 in the British Journal of Pharmacology. ...
