How a plant's refusal to self-pollinate could help India grow more of its own cooking oil

Most people assume plants reproduce through whatever pollen happens to land on them. This is not true. A collaborative research initiative involving the Indian Institute of Technology Gandhinagar (IITGN) has mapped and functionally ...

Scottish 'pregnant grandmother' microbe bursts open after growing offspring within

Scientists have revealed a bizarre microscopic creature that reproduces in a way reminiscent of the horror film" Alien." The microbe grows one or more new cells inside its own body before the outer "mother" cell ruptures ...

First switchable graphene nanoribbon that twists on demand

Researchers at Nagoya University have built a graphene nanoribbon that can switch the direction of its twist using a natural solvent. Graphene nanoribbons are thin, ribbon-shaped structures made of fused carbon rings. Twisted ...

New enzyme mechanism explains how sulfur-reducing bacteria process elemental sulfur

Sulfur-reducing bacteria of the phylum Desulfobacterota play a crucial role in the global biogeochemical sulfur cycle. Species such as Geobacter sulfurreducens use elemental sulfur as a terminal electron acceptor during anaerobic ...

Hidden DNA in medieval gospels reveals history of deadly livestock virus

Some of Europe's most well-known historic manuscripts, including the York Gospels, have proven to be biological time capsules for uncovering the 3,500-year history of the sheeppox virus (SPPV).

New model explains how bacterial promoter elements set gene activity and regulation

Bacterial promoters are DNA sequences that recruit RNA polymerase to initiate transcription, primarily through two elements called −10 and −35. However, the contributions of these elements to promoter evolution and regulation ...

'Pac-Man' enzyme breaks down bioplastics and penicillin in laboratory tests

In the ocean, plastic waste collects to form large garbage patches that endanger marine life. This is partly because the synthetic plastic polymers used today can only be broken down biologically—that is, by microorganisms—at ...

Mammalian genes can combine to make previously unknown mRNAs and proteins

For decades, scientists have understood that each of the roughly 20,000 genes in the human body carries instructions for a single kind of protein. Now, researchers at Harvard Medical School have discovered that instructions ...
