Predator interactions chiefly determine where Prochlorococcus thrive
- ScienceDaily
- 22/1/3 23:22
Where the microbe Prochlorococcus lives is not determined primarily by temperature, as previously thought. A study finds a relationship with a shared predator actually sets the microbe's range. The findings could help scientists predict how Prochlorococcus populations will shift with climate change.
Bringing the sun into the lab
- ScienceDaily
- 22/1/3 20:56
Why the sun's corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A 'hot' trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves travel at the same speed. In an experiment using the molten alkali metal rubidium and pulsed high magnetic fields, researchers...
Lymphoma cell metabolism may provide new cancer target
- ScienceDaily
- 22/1/3 20:56
Aggressive and relatively common lymphomas called diffuse large B cell lymphomas (DLBCLs) have a critical metabolic vulnerability that can be exploited to trick these cancers into starving themselves, according to a new study.
Choline during pregnancy impacts children’s sustained attention

- 22/1/3 20:55
Seven-year-old children performed better on a challenging task requiring sustained attention if their mothers consumed twice the recommended amount of choline during their pregnancy, a new study has found.
When mom talks, are infants with ASD listening?
- ScienceDaily
- 22/1/3 20:55
Researchers pinpoint the regions of the brain and neural mechanisms responsible for normal or impaired development of a child's response to baby talk and why infants with autism do not typically respond well.
Anthropologists study the energetics of uniquely human subsistence strategies
- ScienceDaily
- 22/1/3 20:55
Among our closest living relatives -- the great apes -- we humans are unique: We have larger brains, reproduce more quickly and have longer life spans. These traits are obviously valuable, but the extra energy required to sustain them is quite significant. So how did we manage to afford them?
Gene involved in sense of smell could play a role in the spread of breast cancer to the brain
- ScienceDaily
- 22/1/3 20:54
An olfactory receptor typically associated with the sense of smell may also trigger breast cancer cells to metastasize through a signaling pathway to the brain, bones and lung. Future research could potentially lead to an inhibitor of OR5B21 to prevent cellular invasion and metastasis, thus prolonging the lives of breast cancer patients.
COVID-19 patients have severely increased levels of oxidative stress and oxidant damage, and glutathione deficiency, study finds
- ScienceDaily
- 22/1/3 18:17
Patients hospitalized with COVID-19 had significantly increased levels of oxidative stress and oxidant damage, and markedly reduced levels of glutathione, the most abundant physiological antioxidant, according to a new study.
Researchers develop a model of yeast nuclear pore complex
- ScienceDaily
- 22/1/3 18:17
Using rapid plunge freezing and cryo-EM (electron microscopy) with computational methods, researchers have produced a comprehensive model of the yeast NPC (nuclear pore complex) which reveals the interconnected architecture of its core scaffold.
New method to complete genetic data
- ScienceDaily
- 22/1/3 18:17
Genome sequencing is now much cheaper than it was, but still accounts for a large part of the costs in animal and plant breeding. One trick to reduce these costs is to sequence only a very small and randomly selected part of the genome and to complete the remaining gaps using mathematical and statistical techniques. Researchers have developed a new approach to do this.
More insight into how vision works
- ScienceDaily
- 22/1/3 18:17
Scientists have shed light on an important component of the eye: a protein in the rod cells of the retina which helps us see in dim light. Acting as an ion channel in the cell membrane, the protein is responsible for relaying the optical signal from the eye to the brain. If a genetic disorder disrupts the molecular function in a person, they will go blind. Scientists have deciphered the protein's...

A research collaboration can read out optically previously indistinguishable spin states by using a newly developed spectroscopy method.
3D semiconductor particles offer 2D properties
- ScienceDaily
- 22/1/3 18:17
Researchers have discovered that the junctures at the facet edges of 3D semiconductor particles have 2D properties, which can be leveraged for photoelectrochemical processes -- in which light is used to drive chemical reactions -- that can boost solar energy conversion technologies.
Neuroprotective mechanism altered by Alzheimer's disease risk genes
- ScienceDaily
- 22/1/3 18:17
Researchers have discovered that gene variants associated with risk of developing Alzheimer's disease disturb the brain's natural protective mechanism against the condition.
Lychee genome tells a colorful story about a colorful tropical fruit
- ScienceDaily
- 22/1/3 18:17
Radiant and flavorful, lychees were so beloved that they were domesticated not just once in ancient times, but independently in two different regions of China, a study finds.
Researchers identify biomarker for depression, antidepressant response

Researchers have identified a biomarker in human platelets that tracks the extent of depression.
Self-healing nanomaterials usable in solar panels and other electronic devices
- ScienceDaily
- 22/1/3 16:46
The field of self-repairing materials is rapidly expanding, and what used to be science fiction might soon become reality, thanks to scientists who developed eco-friendly nanocrystal semiconductors capable of self-healing. Their findings describe the process, in which a group of materials called double perovskites display self-healing properties after being damaged by the radiation of an electron...
