Fruit flies offer clues to how brains make reward-based decisions
- ScienceDaily
- 23/9/22 20:12
New research finds fruit flies make decisions based on their expectations about the likelihood of a reward and pinpoints the site in the fly brain where these value adjustments are made, enabling researchers to directly test a theory about how the brain enables this behavior on the level of neural circuits.
Probing the deep genetic structure of Africa
- ScienceDaily
- 23/9/22 20:12
Using ancestry decomposition techniques an international research team has revealed a deeply divergent ancestry among admixed populations from the Angolan Namib desert. This unique genetic heritage brings the researchers closer to understanding the distribution of genetic variation in the broader region of southern Africa before the spread of food production.
Jellyfish, with no central brain, shown to learn from past experience
- ScienceDaily
- 23/9/22 17:08
Even without a central brain, jellyfish can learn from past experiences like humans, mice, and flies, scientists report for the first time. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study challenges previous notions that advanced learning requires a centralized brain and sheds light on the evolutionary roots of learning and memory.

Trigonelline derived from coffee improves cognitive functions in mice
- ScienceDaily
- 23/9/22 17:08
Trigonelline is derived from coffee; researchers have found that it improves spatial learning and memory in senescence-accelerated mice. The study also suggested that this effect results from inhibiting neuroinflammation and restoring neurotransmitter levels in the brain.
Astronomers discover newborn galaxies with the James Webb Space Telescope
- ScienceDaily
- 23/9/22 17:08
With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the Universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed. But for the first time...
Migratory birds can be taught to adjust to climate change
- ScienceDaily
- 23/9/22 17:08
One result of climate change is that spring is arriving earlier. However, migratory birds are not keeping up with these developments and arrive too late for the peak in food availability when it is time for breeding. By getting the birds to fly a little further north, researchers have observed that these birds can give their chicks a better start in life.
Astronomers find abundance of Milky Way-like Galaxies in early Universe, rewriting cosmic evolution theories
- ScienceDaily
- 23/9/22 17:07
Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research.
Same genes behind heart muscle disorders in humans and Dobermanns
- ScienceDaily
- 23/9/22 17:07
Researchers have made a significant finding in determining the genetic background of dilated cardiomyopathy in Dobermanns. This research helps us understand the genetic risk factors related to fatal diseases of the heart muscle and the mechanisms underlying the disease, and offers new tools for their prevention.
Carbon source found on surface of Jupiter's moon Europa

Astronomers using data from NASA's James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Europa.
A network that spreads light and the role of thalamus in our brain
- ScienceDaily
- 23/9/22 17:07
New research using ultra-high field 7 Tesla MRI, provides a better understanding of how light stimulates our brain and could provide new insights into how it works.
Why are you better at recognizing upright faces? Clues from a person who sees the world differently
- ScienceDaily
- 23/9/22 17:07
When you see a familiar face upright, you'll recognize it right away. But if you saw that same face upside down, it's much harder to place. Now researchers who've studied Claudio, a 42-year-old man whose head is rotated back almost 180 degrees such that it sits between his shoulder blades, suggest that the reason people are so good at processing upright faces has arisen through a combination of...

Conversations with plants: Can we provide plants with advance warning of impending dangers?
- ScienceDaily
- 23/9/21 21:45
Plant scientists have engineered a light-controlled gene expression system (optogenetics system) from a prokaryotic system into a eukaryotic system that is tailored for plants.
AI helps bring clarity to LASIK patients facing cataract surgery
- ScienceDaily
- 23/9/21 21:45
Scientists develop computer models of patients' eyes to identify the ideal intraocular lenses and visual simulators for patients to experience how they will see with them.
We could sequester CO2 by 're-greening' arid lands, plant scientists say
- ScienceDaily
- 23/9/21 21:45
Reducing CO2 levels in the atmosphere will take more than cutting emissions -- we will also need to capture and store the excessive volumes of already-emitted carbon. A team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem.
This parasitic plant convinces hosts to grow into its own flesh--it's also an extreme example of genome shrinkage
- ScienceDaily
- 23/9/21 21:45
Balanophora shed one third of its genes as it evolved into a streamlined parasitic plant -- an extreme degree of genome shrinkage even among parasites. Along the way this subtropical plant developed the ability to induce the host plant to grow into the parasite's own flesh -- forming chimeric organs that mix host and parasite tissues.
Dinosaur feathers reveal traces of ancient proteins

Palaeontologists have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution.
How climate warming could disrupt a deep-rooted relationship
- ScienceDaily
- 23/9/21 21:44
Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their...
No shortcuts: New approach may help extract more heat from geothermal reservoirs
- ScienceDaily
- 23/9/21 21:44
Geothermal heat offers a promising source of renewable energy with almost zero emissions, but it remains a relatively expensive option to generate electricity. A new technique may help prevent 'short-circuits' that can cause geothermal power plants to halt production, potentially improving the efficiency of geothermal power, the researchers said.
