Did Iron Suppress Eukaryote Emergence and Early Radiation?
The last eukaryotic common ancestor (LECA) is widely thought to have been an oxygen-respiring organism, arising through endosymbiosis when a free-living bacterium became the mitochondrion.
One Of Earth’s Most Abundant Organisms Is Surprisingly Fragile
A group of ocean bacteria long considered perfectly adapted to life in nutrient-poor waters may be more vulnerable to environmental change than scientists realized.
Tricorder Tech: Cosmic Radiation Aboard Artemis II Orion Will Be Monitored by Six Specialized Chips Supplied by ADVACAM
When, in February March 2026, the massive SLS rocket lifts off from the launch pad at NASA’s Kennedy Space Center in Florida with four astronauts on board, six chips designed […]
The SPIRou Legacy Survey: Detection Of A Nearby World Orbiting In The Habitable Zone Of Gl725B
M dwarfs are prime targets in the search for exoplanets because of their prevalence and because low-mass planets can be better detected with radial velocity (RV) methods. In particular, the […]
Sculpting Of Martian Brain Terrain Reveals The Drying Of Ancient Mars
The Martian brain terrain (MBT), characterized by its unique brain-like morphology, is a potential geological archive for finding hints of paleoclimatic conditions during its formation period.
Millimeter And Submillimeter Spectroscopy Of Methylallene, CH3CHCCH2
Small polycyclic aromatic hydrocarbons and somewhat larger cyano derivatives were detected in the cold dark cloud TMC-1 recently. Their formation from smaller hydrocarbons is not well understood, in part because […]
The Effect of Tidal Heating and Volatile Budgets on the Outgassed Atmosphere of 55 Cancri e
55 Cancri e is a ∼8 Gyr rocky world (1.95 R⊕, 8.8 M⊕) orbiting a K-type star. JWST observations suggest a carbon-dominated atmosphere (CO2/CO) over a global magma ocean (>3000 […]
An Unusual Dust Storm Reveals How Mars Lost Some Of Its Water
The current image of Mars as an arid and hostile desert contrasts with the history revealed by its surface. Channels, minerals altered by water, and other geological traces indicate that […]
This Student Made Cosmic Dust In Her Lab. What She Found Could Help Us Understand How Life Started On Earth
A Sydney PhD student has recreated a tiny piece of the Universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how […]
