A three-year experiment suggests aspen trees may retain chemical traces of previous droughts in their leaves, according to University of Utah biologists. The findings appear to challenge the assumption that trees only record droughts in their growth rings.
A study found that Arabidopsis plants use a bacterial partner to extract iron from soil. The process involves specific root adaptations that may aid nutrient uptake in poor soils.
Researchers observed that certain plant enzymes can differentiate between enantiomers of molecules like menthol and limonene, which have nearly identical structures but different effects.
Scientists identified a marine microbe with the smallest genome yet, which may be able to replicate and express its genetic information.
Researchers used a landscape metaphor to model how embryonic stem cells specialize. Experimental data supports and complicates earlier theoretical ideas.
A study suggests that the sea cucumber Pelagothuria natatrix may play a role in the ocean's carbon cycle. The research, published in Ecology, indicates that these creatures may influence carbon transport in the deep sea.
A study suggests that 3D genome entanglement in coleoid cephalopods could contribute to their advanced nervous systems. The researchers observed patterns in DNA organization that differ from other species.
A study suggests cows can give birth to healthy calves without interferon tau, a protein previously believed necessary for pregnancy. The findings challenge long-held assumptions about early pregnancy in cattle.
A review of 22 studies found that ozone and nitrogen oxides may reduce the ability of bees and moths to detect flower scents. The findings suggest that air pollution could interfere with pollination processes.
Researchers identified three new giant waterlily species in recent years, including one discovered through social media and satellite imagery. The Colombian giant waterlily has pads up to 2 meters wide.
Fossil evidence near Drumheller suggests a small raptor or a juvenile Albertosaurus may have fed on an apex predator. The findings are based on bite marks found on an Albertosaurus skeleton.
Researchers developed a computational model that simulates DNA packaging at a scale more than ten times larger than previous methods. The model tracks how DNA wraps around histones and forms chromatin structures.
The study suggests that in some ant colonies, young workers may start foraging earlier than expected, possibly influenced by colony demands. The researchers observed this behavior in a controlled laboratory setting.
The European nightjar's wings may be adapted for long-distance travel but may limit its ability to maneuver during hunting. The study suggests this could be a trade-off in its flight mechanics.
Genetic analysis suggests some coffee seeds labeled as Sidra may actually be Batian. The study examined a batch of seeds and found genetic profiles inconsistent with their commercial labels.
Gemsbok antelope populations in New Mexico have expanded over 100 kilometers since their introduction in the 1960s and 1970s. The study suggests their range may continue to grow under changing climate conditions.
Researchers observed bogong moths migrating in large numbers during the 2000 Sydney Olympics. The study suggests their movement patterns are consistent with annual migration to the Australian Alps.
Scientists trained sea lions and seals to respond to hearing tests, aiming to understand how human-made noise affects their hearing. The study is ongoing and has not yet drawn definitive conclusions.
Blue damselfish in Okinawa's urban waters show altered gene activity, suggesting potential health impacts from human-impacted environments.
Researchers found that slowing movement and using specific lighting increases visibility of insects during spring. The study suggests these methods may help observers spot more species.
Researchers identified a genetic switch associated with the compound eye structure in butterflies, which may influence their ability to detect a wide range of colors. The study suggests this adaptation could enhance visual acuity in specific light conditions.
A study found that larger dogs may age more rapidly at an epigenetic level, as indicated by chemical tags on their DNA. The results are based on observations of a limited number of dogs and require further research.
