More adaptable crops are needed to address global hunger and worsening challenges in food production. Researchers have now developed new genetic blueprints for two types of groundcherry. Their work can help unlock the potential for orphan crops like groundcherry to strengthen global food supplies. It may also help reveal how plants evolve and develop new traits.

New research changes our understanding of seasonal thawing in parts of Antarctica, as scientists have learned that summer thawing occurs nearly a month earlier, and stays thawed for a full two months longer than previously believed.

Researchers have developed and validated a machine learning--based method to predict which patients with early-stage melanoma are most likely to experience a cancer recurrence.

A first-of-its-kind study reveals alarming findings about the level of microplastic pollution on Israel's beaches.

A study warns that safety flag systems differ even between beaches in close proximity to each other, and that this lack of uniformity may be due to an outdated legal framework and the absence of an agreed system between different organizations. They propose that a specific guide to beach safety flags and signage as part of an agreed national safety plan could be a solution.

Bizarre quantum properties of black holes -- including their mind-bending ability to have different masses simultaneously -- have been confirmed by physicists.

New research into the drivers of mangrove loss over the past 20 years has revealed that most of the degradation can be attributed to socio-economic and biophysical factors, with mangrove cover increasing in some areas.

Scientists have managed for the first time to create a unidirectional device that significantly increases the quality of a special class of transmitted signals in optical communications: optical vortices. By transmitting selective optical vortex modes exclusively unidirectionally, the developed device largely reduces detrimental backscattering to a minimum. The scientists emphasize the great...

Scientists reveal another factor implicated in the aging process -- a class of lipids called SGDGs (3-sulfogalactosyl diacylglycerols) that decline in the brain with age and may have anti-inflammatory effects. The research helps unravel the molecular basis of brain aging, reveals new mechanisms underlying age-related neurological diseases, and offers future opportunities for therapeutic...

Engineering researchers have developed a new self-healing composite that allows structures to repair themselves in place, without having to be removed from service. This latest technology resolves two longstanding challenges for self-healing materials, and can significantly extend the lifespan of structural components such as wind-turbine blades and aircraft wings.

Researchers have developed a computational method to map the architecture of human tissues in unprecedented detail. Their approach promises to accelerate studies on organ-scale cellular interactions and could enable powerful new diagnostic strategies for a wide range of diseases.

Researchers have found that a system based on ion-sensitive field effect transistors -- a tiny electrical circuit that is activated by a change in pH -- and enzymatic chemical signal amplification can accurately detect EGFR on breast cancer cells. This technology has the potential to be used with multiple markers simultaneously to assess cancer patient status from liquid biopsy samples.

Researchers and others report that more than one-third of the COVID-19 patients who did not receive any treatment experienced complete resolution of symptoms for at least two consecutive days, but then subsequently reported a return of symptoms.

Engineers and scientists have discovered a low-energy, one-step photocatalytic method for converting the problematic industrial pollutant hydrogen sulfide -- a gas with the unmistakable odor of rotten eggs -- into valuable hydrogen gas and sulfur.

A team of quantum physicists has established a new method to observe vortices in dipolar quantum gases. These quantum vortices are considered a strong indication of superfluidity, the frictionless flow of a quantum gas, and have now been experimentally detected for the first time in dipolar gases.

There has long been an assumption that a connection exists between affective polarization and anti-democratic attitudes. A new study tests several depolarization interventions and finds that, while they depolarize, they do not affect anti-democratic attitudes.

Researchers have created a newborn hearing screening system that uses cheap earbuds and a smartphone instead of an expensive commercial device.

Twilight observations have enabled astronomers to spot three near-Earth asteroids (NEA) hiding in the glare of the Sun. These NEAs are part of an elusive population that lurks inside the orbits of Earth and Venus. One of the asteroids is the largest object that is potentially hazardous to Earth to be discovered in the last eight years.

A new protocol extends live imaging time for C. elegans larvae and adults using light sheet fluorescence microscopy from 20 minutes to more than 2 hours, while avoiding heat stress in the specimen.

Hair loss is undesirable for many men -- and women -- because one's hairstyle is often closely tied to their self-confidence. And while some people embrace it, others wish they could regrow their lost strands. Now, researchers have used artificial intelligence (AI) to predict compounds that could neutralize baldness-causing reactive oxygen species in the scalp. Using the best candidate, they...

Despite the broad recognition of mimicry among bumble bees, distinct North American mimicry rings have yet to be defined, due in part to the prevalence of intermediate and imperfect mimics in this region. Scientists employ a generalization approach using human perception to categorize mimicry rings among North American bumble bees. They then then map species distributions on North American...

Climate change will increase opportunities to see rainbows, according to a new study. The study's authors estimate that by 2100, the average land location on Earth will experience about 5% more days with rainbows than at the beginning of the 21st century.

An international study shows that the number of atmospheric aerosol particles measured at observation sites across Europe has, on average, declined since the beginning of the 2000s. The declining trend was also observed by the climate models studied, but on average the relative decrease was lower in the models than in the ground measurements. There are clear differences between different models in...

Researchers have determined the three-dimensional structure of the proteolytic enzyme PAPP-A. The results may allow us to better understand the basic biology that regulates linear growth of vertebrates. The same regulatory mechanisms are also involved in several age-related diseases, and thus, the research is an important step towards the development of novel types of drugs.
