The protein catalogue gives a dynamic picture of the mitochondria, beyond what was known from humans and yeast. Credit: Dr David Furness/Keele University/SPLScientists have mapped in unprecedented detail the proteins that make up the mitochondria in six organisms — five single-celled parasites and one plant — spanning the eukaryotic tree of life. The findings, described in nine papers published in Cell, Cell Press Blue, Molecular Cell and Current Biology on 1 October1–9, reveal dozens of proteins that are not found in humans but are shared among parasites, including some that cause malaria or sleeping sickness. The findings might help scientists to devise new treatments for these illnesses. The work has also stirred a long-running debate about the origin of the mitochondrion. Cells are swapping their mitochondria. What does this mean for our health? Best known as the powerhouse of the eukaryotic cell because it produces energy, the mitochondrion has its own tiny DNA, which is distinct from that of the cell’s nucleus. But both mitochondrial and nuclear DNA encode the proteins that make up this organelle.

Sleep difficulties are especially common during middle age, including among women in their 40s and 50s. New research suggests that an aromatic oil made from the roots of Hinoki (Chamaecyparis obtusa), also known as Japanese cypress, could offer a simple way to support better sleep at home. In a study published September 1, 2026, in the Journal of Wood Science, researchers tested Hinoki root essential oil and found several encouraging signs. Participants experienced fewer awakenings during the night, reported feeling better in the morning, and showed brain wave patterns associated with a smoother transition into sleep.

What researchers uncovered through lab testing and surveillance footage, prosecutors said, was a plot by his fellow graduate student to intentionally poison him.

Omar’s legal team says the search violated safeguards designed to protect constitutional rights of members of Congress. Lawyers for Democratic United States Representative Ilhan Omar of Minnesota have demanded the return of property seized in a federal raid of her Washington, DC home, accusing the US Department of Justice of conducting a politically motivated investigation and failing to follow judicial instructions during the search. “The political motivations behind this pre-election investigation and search are clear as day,” Omar’s lawyers wrote in a letter sent to federal prosecutors on Friday and obtained by The Associated Press news agency.
