Study seeks to answer whether effects of 'abortion pill' can be reversed
- ScienceDaily
- 19/12/5 23:13
Women who initiate medical abortion but opt to stop in the middle of treatment may be at risk for serious blood loss, a study finds. Researchers found this is true even for women who use an experimental treatment that claims to 'reverse' the effects of the abortion pill. The study provides important insights into the safety of using high doses of progesterone during early pregnancy to try to stop...

As China rapidly adopts clean energy, use of traditional stoves persists
- ScienceDaily
- 19/12/5 21:53
Old habits are hard to break. A new study of replacement of traditional wood and coal burning stoves with clean energy in China suggests that, without a better understanding of the reasons behind people's reluctance to give up traditional stoves, it will be difficult for policies in China and elsewhere in the world to succeed in encouraging this shift towards clean energy.

- ScienceDaily
- 19/12/5 21:53
The discovery of how a 'beam' in human bone material handles a lifetime's worth of wear and tear could translate to the development of 3D-printed lightweight materials that last long enough for more practical use in buildings, aircraft and other structures.
Open source EEG visualization tool

- 19/12/5 21:53
Researchers have developed a free open source computer program that can be used to create visual and quantitative representations of brain electrical activity in laboratory animals in hopes of developing countermeasures for opioid use disorder.
Cellphone distraction linked to increase in head injuries
- ScienceDaily
- 19/12/5 21:53
Head and neck injuries incurred while driving or walking with a cellphone are on the rise -- and correlates with the launch of the iPhone in 2007 and release of Pokémon Go in 2016, a new study found.
NASA's OSIRIS-REx mission explains Asteroid Bennu's mysterious particle events
- ScienceDaily
- 19/12/5 20:51
Shortly after NASA's OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission's science team revealed that the asteroid could be active, or consistently discharging particles into space.
Developing a digital twin of a vehicle
- ScienceDaily
- 19/12/5 20:51
In the not too distant future, we can expect to see our skies filled with unmanned aerial vehicles delivering packages, maybe even people, from location to location. Researchers are developing 'digital twins' that combine computational models and machine learning to predict vehicle health and enable autonomous decision-making at the edge.
Recycling nutrient-rich industrial waste products enhances soil, reduces carbon

Recycling biotechnology byproducts can enhance soil health while reducing carbon emissions and maintaining crop yields.
Behavioral interventions may be as effective at reducing food intake as anorectic drugs
- ScienceDaily
- 19/12/5 20:18
Simulations predict that behavioral interventions such as imposing strict no-food restrictions after meals can be as effective as strong anorectic drugs in reducing food intake in rodents, according to a study.
Rats exchange information about danger in a reciprocal fashion

Organizations aren't moving quickly enough on cyber security threats linked to the drive toward using personal mobile devices in the workplace.
Newly engineered peptide shows potential as long-acting anti-HIV drug
- ScienceDaily
- 19/12/5 20:17
A newly engineered peptide called IBP-CP24 has the potential to be further developed as a long-acting anti-HIV drug that can be used alone or in combination with a broad neutralizing antibody for the treatment and prevention of HIV-1 infection, according to a new study.
Dull teeth, long skulls, specialized bites evolved in unrelated plant-eating dinosaurs
- ScienceDaily
- 19/12/5 20:17
Herbivorous dinosaurs evolved many times during the 180 million-year Mesozoic era, and while they didn't all evolve to chew, swallow, and digest their food in the same way, a few specific strategies appeared time and time again. An investigation of the skulls of 160 non-avian dinosaurs revealed the evolution of common traits in the skulls and teeth of plant-eating members of otherwise very...
Nervous system doesn't merely detect Salmonella, it defends the body against it

Study in mice shows the nervous system not only detects the presence of Salmonella in the gut but actively stops the organism from infecting the body.
Root of childhood kidney cancer discovered
- ScienceDaily
- 19/12/5 20:17
A fundamental change in our understanding of the childhood kidney cancer Wilms' tumor is on the horizon, after the discovery of its earliest genetic root by scientists. By comparing genome sequences from normal kidney tissue and tumors, the team identified patches of normal-looking kidney tissue that in fact carried DNA changes that cause Wilms' tumor.

Tropical species are six times more sensitive to forests being broken up for logging or farming than temperate species, says new research.
Clinical study finds eating within 10-hour window may help stave off diabetes, heart disease
- ScienceDaily
- 19/12/5 20:17
Researchers have found that a 10-hour time-restricted eating intervention, when combined with traditional medications, resulted in weight loss, reduced abdominal fat, lower blood pressure and cholesterol for participants. The pilot study could lead to a new treatment option for metabolic syndrome patients who are at risk for developing life-altering and costly medical conditions such as diabetes.
Three types of cells help the brain tell day from night

- 19/12/5 20:17
Researchers report the discovery of three cell types in the eye that detect light and align the brain's circadian rhythm to our ambient light. The study marks the first direct assessment in humans of light responses from these cells, called intrinsically photosensitive retinal ganglion cells (ipRGCs) -- and the implications for health are substantial.

Technique shows how individual cancer cells react to drugs
- ScienceDaily
- 19/12/5 20:17
sci-Plex, a new cell-response screening method, pools genetically different cells and shows what happens to individual cells when the sample is treated, such as with cancer drugs.
