Personalizing treatment for severe limb injuries
- ScienceDaily
- 22/1/10 20:53
Scientists have developed an innovative technique using small wearable sensors to gather data on how people -- who have suffered from a traumatic hand amputation -- use a prothesis versus a transplanted hand in everyday life. So far, the data shows people with a transplanted hand demonstrate a more balanced use of their hands than those who use a prothesis.
The ‘surprisingly simple’ arithmetic of smell

- 22/1/10 20:52
Consuming more than 7 grams (>1/2 tablespoon) of olive oil per day is associated with lower risk of cardiovascular disease mortality, cancer mortality, neurodegenerative disease mortality and respiratory disease mortality, according to a new study. The study found that replacing about 10 grams/day of margarine, butter, mayonnaise and dairy fat with the equivalent amount of olive oil is associated...
Gauging the resilience of complex networks
- ScienceDaily
- 22/1/10 19:27
Whether a transformer catches fire in a power grid, a species disappears from an ecosystem, or water floods a city street, many systems can absorb a certain amount of disruption. But how badly does a single failure weaken the network? And how much damage can it take before it tips into collapse?
New approach can help identify young children most at risk for obesity
- ScienceDaily
- 22/1/10 19:27
Newly developed risk scores synthesize genetic information into an easy-to-interpret metric that could help clinicians identify young children most at risk of developing obesity. The study used a novel statistical methods to establish scoring criteria using data collected from children from birth to three years of age.
New neural circuits discovered that regulate spatial learning and memory in the brain’s hippocampal formation
- ScienceDaily
- 22/1/10 17:41
A research team has discovered new neural circuits that regulate spatial learning and memory in the brain's hippocampal formation. The team identified novel functional roles of new circuit connections between the venal CA1 region and dorsal CA3 regions of the hippocampus and demonstrated that genetic inactivation of this projection impairs object-related spatial learning and memory, but does not...
Researchers develop optical biopsy system that detects liver cancer
- ScienceDaily
- 22/1/10 17:41
Researchers have developed an optical biopsy system that can distinguish between cancerous and healthy liver tissue. The technology makes use of diffuse reflectance spectroscopy and lifetime fluorescence measurements to evaluate makers of cellular metabolism that differ between healthy and cancerous cells. The system has higher accuracy than traditional biopsies, possibly making liver cancer...
Water scarcity may spur improvements at manufacturing facilities
- ScienceDaily
- 22/1/10 17:41
As climate change continues and the incidences of drought rise, water is increasingly becoming scarce for manufacturing. But a new study suggests that there is a silver lining -- companies that use water may pivot to become efficient and more eco-friendly during periods of water scarcity.
Astronomers identify potential clue to reinonization of universe
- ScienceDaily
- 22/1/10 17:41
Astronomers have identified a potential clue to how the universe became reionized after the Big Bang. The researchers identified a black hole, a million times as bright as our sun, that may have been similar to the sources that powered the universe's reionization.
Unexpected benefits from food competitors
- ScienceDaily
- 22/1/10 17:41
A research team has found that gravid tobacco hawkmoths (Manduca sexta) show an unusual preference for Datura plants that are already infested with leaf beetles when laying their eggs. The beetles and their larvae actually compete with tobacco hornworms, the larvae of Manduca, for food. Plants infested by beetles change their odor profile and increase the production of the substance alpha-copaene,...
Ocean physics explain cyclones on Jupiter
- ScienceDaily
- 22/1/10 17:41
Images from NASA's June Spacecraft have given oceanographers the raw materials for a new study that describes the rich turbulence at Jupiter's poles and the physical forces that drive the large cyclones.
Recent growth and sudden declines in Antarctic sea ice to be unique changes since the early 20th century
- ScienceDaily
- 22/1/10 17:41
Researchers show that the increase of sea ice surrounding Antarctica since 1979 is a unique feature of Antarctic climate since 1905 -- an observation that paints a dramatic first-ever picture for weather and climate implications on the world's southernmost continent.
Vaccinated women pass COVID-19 antibodies to breastfeeding babies, study finds

Women vaccinated against COVID-19 transfer SARS-CoV-2 antibodies to their breastfed infants, potentially giving their babies passive immunity against the coronavirus, according to new research.
Measuring trust in AI
- ScienceDaily
- 22/1/10 16:33
Prompted by the increasing prominence of artificial intelligence (AI) in society, researchers investigated public attitudes toward the ethics of AI. Their findings quantify how different demographics and ethical scenarios affect these attitudes. As part of this study, the team developed an octagonal visual metric, analogous to a rating system, which could be useful to AI researchers who wish to...
