Gold nanoparticles distinguish two forms of tryptophan in lab
The two tryptophan forms produced different colors and particle arrangements, while absorbance at one wavelength tracked the share of d-tryptophan in test mixtures.

Computer Models Identify Distinct Bone Targets for Four Epilepsy Drugs
A network analysis linked four conventional antiepileptic drugs to different osteoporosis-related protein hubs. Docking and molecular-dynamics results added detail, but the findings remain preliminary signals rather than clinical evidence.

Nickel Thiophene Hybrid Binds Most Strongly to Copper Oxide
In a laboratory comparison, NiPc-OTh showed the strongest measured interaction with Cu2O, while thiophene-anchored variants recorded higher CO activity on carbon nanotubes than unanchored NiPc.

Zingiberene formulation tied to higher mineral markers in rats
A rat study found higher serum calcium, phosphate and alkaline phosphatase in fracture groups receiving free zingiberene or a zingiberene-selenium formulation than in fracture controls. The formulation's alkaline phosphatase reading was higher than free zingiberene's, but magnesium did not differ significantly between treatments.

Hydrogel carrying glycopeptide linked to faster wound healing in mice
A hydrogel carrying Lycium barbarum glycopeptide released more cargo under acidic lab conditions and was associated with faster wound closure in mice, but the study did not establish long-term safety or performance in other wound models.

New model maps how small molecules bind disordered proteins
A model built from fleeting residue contacts produced affinity estimates for Aβ42 and alpha-synuclein systems, but its validation remained imperfect.

Review maps how hybrid light-matter systems move energy and charge
A literature-based Feature Article traces how polaritonic systems exchange energy, carry excitations and show reported changes in charge mobility, while highlighting gaps in the models used to describe them.

Cyanobacteria-made catalyst breaks down more crystal violet
A catalyst made with cyanobacterial extract achieved higher reported crystal violet degradation and total organic carbon removal than chemically synthesized NiO/CoO, though the tests used prepared dye solutions rather than real wastewater.

Study reports fast reactions with walnut-shell biochar in water
Amine-functionalized biochar made from walnut shells produced high reported yields for two reaction types in water at room temperature, but the study was small and descriptive.

Leaf-made zinc oxide nanoparticles show strong corrosion inhibition
The study compared Bauhinia purpurea leaf-extract-mediated zinc oxide nanoparticles made by co-precipitation and sol-gel synthesis in carbon-steel corrosion tests, with lower dissolved iron reported at 100 ppm than in the blank.

Alkali-intercalated WTe2 shows a new structure and narrow gaps
Intercalated WTe2 compounds containing potassium, rubidium or cesium showed a lower-symmetry crystal arrangement and progressively wider spacing between layers. Optical analysis and DFT calculations indicated narrow gaps, while temperature-dependent electrical measurements reported semiconducting behavior for Rb0.5WTe2 crystals.

Preprint links native defects to α-MnO₂’s electronic and optical behavior
A computational preprint models native interstitial, vacancy and antisite defects in ground-state C2-type antiferromagnetic α-MnO₂. It reports the oxygen vacancy as the most stable neutral defect, strong donor–acceptor compensation and defect-related sub-gap optical features, while stressing that equilibrium carrier type and real-world defect populations remain unestablished.
