Recent reporting, background, and summaries from the science desk.
Researchers at the University of Helsinki have uncovered an "oxygen tug of war" within plant cells, where mitochondria actively draw oxygen from chloroplasts, significantly altering photosynthesis and reactive molecule production. This groundbreaking discovery reveals a novel mechanism for how plants respond to stress and regulate oxygen, offering crucial insights that could lead to improved crop varieties.
A groundbreaking brain-imaging study reveals ketamine rapidly alleviates treatment-resistant depression by reshaping a crucial brain receptor vital for neuronal communication. This pivotal change occurs in brain regions linked to mood and reward, directly correlating with symptom improvement and paving the way for more personalized therapies.
A CBS News segment, "Zoomin' with Zoe," presents compelling scientific evidence for climate change, revealing NASA data that confirms a consistent and rapid global warming trend since 1970. This unprecedented pace of change poses significant threats to global ecosystems, biodiversity, and various species, demanding urgent attention.
Chinese scientists have reportedly made a groundbreaking discovery using a lunar clock, revealing that time on the Moon behaves unexpectedly and deviates from Einstein's theory of relativity. This significant finding challenges our fundamental understanding of physics and could lead to new insights into the nature of time and gravity.
A new study from a German climate institute reveals that global warming has significantly accelerated in the past decade, confirming long-held scientific concerns. This alarming acceleration suggests a key Paris Agreement target could be surpassed before 2030, demanding urgent and intensified global action.
Scientists have uncovered over 200 metabolic enzymes directly on human DNA, revealing a previously unknown "mini-metabolism" within the cell's nucleus that challenges traditional biological understanding. This groundbreaking discovery suggests these enzymes influence crucial processes like gene expression and DNA repair, potentially revolutionizing our approach to cancer treatment and understanding drug resistance.
Scientists have successfully synthesized "half-Möbius molecules," a groundbreaking new topological structure previously unknown in chemistry. These unique molecules are defined by a distinct 90-degree twist per revolution and require four circumnavigations to return to their origin, opening exciting new possibilities for molecular research.
Scientists have identified Aurora-related kinase 1 (ARK1) as a crucial protein for the malaria parasite's reproduction, demonstrating that disabling it effectively halts the disease's spread in both human and mosquito hosts. This groundbreaking discovery offers a promising new target for developing highly specific antimalarial drugs that could revolutionize treatment by attacking the parasite without harming human cells.
Researchers have accidentally discovered a bioengineered algae strain that effectively removes microplastics from water, offering a promising new solution to widespread plastic pollution. This innovative algae works by clumping onto microplastics, causing them to sink for easier collection and potential recycling.
A new study reveals that the incredibly tough bacterium *Deinococcus radiodurans* can survive extreme impact forces, mimicking those of asteroid collisions, even at pressures up to 3 GPa. This groundbreaking discovery significantly bolsters the theory of panspermia, suggesting life could potentially hitchhike between planets after major cosmic events.
A spectacular "blood moon" total lunar eclipse is set to grace the skies on March 3, 2026, offering a stunning celestial show visible across North America, Australia, New Zealand, and eastern Asia. This significant event marks the first lunar eclipse of the year and the last total eclipse until December 2028, with some regions even getting a rare glimpse of a selenelion.
Astronomers have unveiled an astonishingly detailed image of the Milky Way's heart, captured by the ALMA Telescope in Chile, revealing an intricate web of cosmic gas filaments. This unprecedented view will allow scientists to explore star formation in extreme conditions near our galaxy's supermassive black hole and uncover its hidden chemistry.
