Bioengineers have developed a way to grow engineered skin in three-dimensional shapes, including a seamless 'glove' of skin that could be slipped onto a severely burned hand.
Warmer climate may drive fungi to be more dangerous to our health
- ScienceDaily
- 23/1/31 22:05
A new study finds that raised temperatures cause a pathogenic fungus known as Cryptococcus deneoformans to turn its adaptive responses into overdrive. Heat increases its number of genetic changes, some of which might presumably lead to higher heat resistance, and others perhaps toward greater disease-causing potential.
Researchers take a step toward novel quantum simulators
- ScienceDaily

If scaled up successfully, the team's new system could help answer questions about certain kinds of superconductors and other unusual states of matter.
With rapidly increasing heat and drought, can plants adapt?
- ScienceDaily
- 23/1/31 22:05
As deserts expanded their range over the past 5-7 million years, many plants invaded the new biome and rapidly diversified, producing amazing adaptations to drought and heat. Can plants continue to adapt to increasing aridity caused by climate change? A new study that addressed the origins of desert adaptation concluded that one group of desert plants, rock daisies, came preadapted to aridity,...
Aquatic organisms respond to flooding and drought disturbance in different ways
- ScienceDaily
- 23/1/31 19:10
Populations of various species of aquatic insects and other invertebrates respond to flooding and waterway drying due to drought in different ways that can be anticipated, according to a new study that employed a novel method to assess the stability of stream ecosystems.
Deer browsing is just one of many factors shaping North American forests
- ScienceDaily
- 23/1/31 19:10
In a new study, a research team discovered evidence that browsing by white-tailed deer had relatively little long-term impact on two tree species in a northern forest.
New live bacterial product for stubborn superbug improves quality of life
- ScienceDaily
- 23/1/31 19:09
The stubborn superbug Clostridium difficile, or C. diff, may have met its match. A esearcher is reporting the first well-controlled study to demonstrate the effectiveness of a new medicine for patients with the debilitating recurrent infection and disease.
How sound waves trigger immune responses to cancer in mice
- ScienceDaily
- 23/1/31 19:09
When noninvasive sound waves break apart tumors, they trigger an immune response in mice. By breaking down the cell wall 'cloak,' the treatment exposes cancer cell markers that had previously been hidden from the body's defenses, researchers have shown.
Biorefinery uses microbial fuel cell to upcycle resistant plant waste
- ScienceDaily
- 23/1/31 19:09
Researchers have developed a sustainable, inexpensive two-step process that can upcycle organic carbon waste -- including lignin, a difficult-to-breakdown material that gives plants their structure. By processing waste through a microbe-driven biorefinery, the researchers turned lignin into carbon sources that could be used in high-value, plant-derived pharmaceuticals and antioxidant...
Scientists release newly accurate map of all the matter in the universe
- ScienceDaily
- 23/1/31 19:09
A group of scientists have released one of the most precise measurements ever made of how matter is distributed across the universe today.
How to make hydrogels more injectable
- ScienceDaily
- 23/1/31 18:44
A new computational framework can predict the structures, properties, and performance of granular hydrogels. The new model could one day make it easier to design the right gel for a particular biomedical application.
More variability helps learning

Variable stimuli influence learning processes in the visual system.
Understanding plants can boost wildland-fire modeling in uncertain future
- ScienceDaily
- 23/1/31 18:44
A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.
New vaccine targets life-threatening fungal infections, a growing health concern
- ScienceDaily
- 23/1/31 18:44
A new vaccine could be the first clinically approved immunization to protect against invasive fungal infections, a growing concern as antifungal drug resistance increases. Fungal infections cause more than 1.5 million deaths worldwide each year and cost billions. They also double hospitalization costs, double the length of hospital stays and double the risk of death in hospitalized patients,...
'Ghostly mirrors' for high-power lasers
- ScienceDaily
- 23/1/31 18:44
Laser-driven 'mirrors' capable of reflecting or manipulating light have been produced.
When bugs swipe left
- ScienceDaily
- 23/1/31 18:44
A single protein called Gr8a is expressed in different organs in male and female flies and appears to play an inhibitory role in mating decision-making. The findings point to one of the ways that flies could put up behavioral barriers to protect against mating with the wrong kind of partner.
Migraine associated with increased risk for pregnancy complications
- ScienceDaily
- 23/1/31 18:44
Women are disproportionately affected by migraine, especially during their reproductive years. However, the relationship between migraine and adverse pregnancy outcomes has not been well understood. A new study analyzed data from thousands of women from the Nurses' Health Study II to assess the relationship between migraine and pregnancy complications.
Can a computer teach babies to count?
- ScienceDaily
- 23/1/31 18:44
A recent study of 81 babies between 14 and 19 months old found the same outcome: When these babies watched a video where they were shown pictures of toy cars and toy pigs and listened to someone count out loud prior to the toys being hidden in a box -- similar to an earlier study done in person -- the babies looked longer when the box was lifted and some of the objects disappeared. When there was...
Transforming the way cancer vaccines are designed and made
- ScienceDaily
- 23/1/31 18:44
A new way to significantly increase the potency of almost any vaccine has been developed. The scientists used chemistry and nanotechnology to change the structural location of adjuvants and antigens on and within a nanoscale vaccine, greatly increasing vaccine performance in seven different types of cancer. The architecture is critical to vaccine effectiveness, the study shows.

Moderate and intense physical activity favors good sleep
- ScienceDaily
- 23/1/31 16:19
Proper sleep is critical for the maintenance of good health, and vice versa -- a healthy lifestyle has been found to improve sleep quality. To better examine the relationship between physical activity and sleep, a team of researchers conducted a comprehensive study among middle-aged Japanese people. By outlining the factors improving sleep quality, this line of research can hopefully help in...
