A haplotype-based breeding framework for the precise pyramiding of elite QTL alleles: a lettuce case study

The efficient pyramiding of favorable alleles underlying complex traits remains a major challenge in crop breeding as most quantitative trait loci (QTLs) have not been resolved to causal genes, limiting their direct application in marker-assisted breeding. Although haplotypes provide more informative genetic units than individual markers, existing haplotype-based studies have largely focused on…

IIM Indore Study Finds ‘Good Enough’ Decisions Can Reduce Uncertainty In Short-Term Projects

Indore (Madhya Pradesh): In a finding that could reshape how managers make decisions in uncertain and rapidly changing business environments, a new study by Indian Institute of Management Indore has found that choosing a “good enough” solution rather than constantly pursuing the optimal one can substantially reduce uncertainty…

Flightless beetles evolved distinct snail-hunting shapes on Japan's largest island

Islands are widely recognized as natural laboratories of evolution. The ocean restricts movement among islands, allowing isolated populations to adapt to different environments and, at times, diverge into new species.

Scientists map the microscopic roots of chaos in dusty plasma using supercomputer simulations

Research Matters Staff Writer(s) Jammu 17 Aug 2026 Researchers have achieved a breakthrough in understanding the chaotic world of turbulence by tracking the movement of millions of individual particles in a specialised state of matter known as dusty plasma.

Scientists map microscopic origins of turbulence in dusty plasma using supercomputer simulations.
Understanding dusty plasma turbulence could improve plasma containment in nuclear fusion reactors.
