When the rapid adaptation of sales channels pays off‎

Greater agility in the sales system—that is, a company's ability to rapidly adapt its sales channels to changing market conditions—is associated with higher operating profit, but only under certain conditions. That is the result of an observational, survey-based study involving 356 predominantly European companies carried out by retail and marketing experts from the University of Cologne, the École des hautes études commerciales Paris (HEC Paris), the University of Mannheim and the University of Manchester.

Peptide alternative to antibiotics could combat antimicrobial resistance crisis‎

A University of Alberta research team has designed a promising alternative for treating antimicrobial-resistant infections, a pressing global health issue. In a paper recently published in Cell Biomaterials, the team describes preclinical testing results for its human-derived peptide treatment, D-GK17. The peptide is stable and nontoxic to humans and is synthesized to attack the surfaces of bacterial or fungal cells that create biofilms, a sticky matrix that is often impenetrable to antibiotic treatments.

Burned-home soils showed uneven lead, arsenic contamination after Los Angeles wildfires‎

A chemical analysis of residential soils and ash around California homes burned by the Eaton and Palisades wildfires in early 2025 revealed wide variation in contamination by potentially harmful elements, including lead, according to a study published in Environmental Science and Technology Letters on May 12. The researchers made their findings available to the Los Angeles Public Health Department over the course of the study.

New research identifies types of dishonesty that occur in a relationship—and their consequences‎

From "harmless" white lies to infidelity, dishonesty in romantic relationships is a complex phenomenon that takes on many forms. New research from the University of Copenhagen shows that while dishonesty between partners often fuels distrust and resentment, it may also, in some cases, help couples solve issues and repair their bond.

World's largest particle smasher halts for upgrade to boost hunt for dark matter‎

The world's most powerful particle accelerator will shutter operations Monday for four years of renovations to dramatically boost its collision capacity and the potential for unlocking one of the greatest mysteries of the universe: dark matter.

Lithium-doped carbon nanorings show promise for next-generation optical devices‎

Nonlinear optical materials are essential for advanced photonics and laser technologies, but researchers are still searching for ways to optimize organic, carbon-based alternatives. Using computational modeling, scientists demonstrated that adding a lithium atom to the outside of a carbon molecule made of 12 benzene rings creates a material with exceptionally strong optical responses.

Newly identified fossil sheds light on evolutionary history of saber-toothed cats‎

Fossils tucked away in a museum drawer and identified merely as "feline" are actually from a very ancient and enigmatic saber-toothed cat that inhabited North America more than 5 million years ago. Newly identified by a UC Berkeley paleontologist, the nearly complete skull helps clarify how these large-fanged felines evolved over millennia before going extinct about 10,000 years ago.

Laser-based 3D imaging system enables precise detection and quantification of methane leakage‎

A research team led by Prof. Zhang Zhirong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a high-performance laser-based three-dimensional methane gas cloud imaging telemetry system that enabled visualization of microleakages, accurate location of leakage sources and quantitative retrieval of emission rates.

New millisecond pulsar discovered with the Murchison Widefield Array‎

Using the Murchison Widefield Array (MWA), astronomers have discovered a new millisecond pulsar as part of the ongoing Southern-sky MWA Rapid Two-metre (SMART) survey. The discovery is reported in a research paper published June 17 on the arXiv preprint server. The work has also been accepted for publication in The Astrophysical Journal Letters.

New workflow transforms nonfunctional protein scaffolds into active enzymes‎

Enzymes are regarded as the key to sustainable chemistry. Despite major advances in protein design, creating artificial enzymes from scratch has so far remained a grand challenge. A research team at the University of Bayreuth, in collaboration with scientists from the University of Ottawa, has now demonstrated how nonfunctional protein scaffolds can be transformed into highly active enzymes. The researchers report their findings in Nature Chemical Biology.
