New research has found that venetoclax, a medication currently approved for leukemia, has benefits for patients with multiple myeloma when used in combination with another drug. This discovery offers a new avenue of treatment options for the currently incurable disease.

Researchers have provided fresh insight into the dangers some common household chemicals pose to brain health. They suggest that chemicals found in a wide range of items, from furniture to hair products, may be linked to neurological conditions.

Scientists have discovered how honeybees can decipher dances by their hive mates that relay directions to food.

Coastal seas form a complex transition zone between the two largest CO2 sinks in the global carbon cycle: land and ocean. Ocean researchers have now succeeded for the first time in investigating the role of the coastal ocean in a seamless model representation.

Physicists are also interested in fish -- above all when they are researching the formation of structures. A research team has examined the schooling behavior of zebra danio (Danio rerio, also known as 'zebrafish') using methods from the field of multi-particle physics. They explain that groups of just three fish already move in a similar way to large schools while, by contrast, two fish display completely different behavior.

Research has often focused on how teachers and educators can best instruct and accommodate students with disabilities. However, are the methods used to teach students with disabilities effective and inclusive for all students?

A real-world study has shown that the use of cool paint coatings in cities can help pedestrians feel up to 1.5 degrees Celsius cooler, making the urban area more comfortable for work and play.

A team of scientists has developed a novel antibiotic named COE-PNH2 that is capable of combating hard-to-treat mycobacterial lung infections. Such infections, which are notorious for resisting conventional treatment, pose a serious health threat, especially to the elderly and those with underlying conditions.

Beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while -- but over time, the color changes and needs to be renewed. Now, special titanium oxide nanoparticles have been developed that can be added to ordinary, commercially available wall paint to establish self-cleaning power: The nanoparticles are photocatalytically active, they can use sunlight not only to bind substances from the air...

While Hollywood and Silicon Valley love the limelight, California is an agricultural powerhouse, too. Agricultural products sold in the Golden State totaled $59 billion in 2022. But rising temperatures, declining precipitation and decades of over pumping may require drastic changes to farming. Legislation to address the problem could even see fields taken out of cultivation.

Humans pass on more viruses to domestic and wild animals than we catch from them, according to a major new analysis of viral genomes.

More efficient use of phosphorus could see limited stocks of the important fertilizer last more than 500 years and boost global food production to feed growing populations. But these benefits will only happen if countries are less wasteful with how they use phosphorus, a study shows. Around 30-40 per cent of farm soils have over-applications of phosphorus, with European and North American countries over-applying the most.

Scientists have discovered a gene mutation is responsible for causing psoriasis -- a chronic inflammatory skin disease that causes patients to develop red, scaly and itchy patches across their body. According to researchers, if two copies of this mutated gene (known as IKBKB) are present, patients with psoriasis may go on to develop psoriatic arthritis, leaving them with joint pain, stiffness and swelling. It's hoped the findings will lead to improved diagnosis and treatment for patients with psoriasis... Читать дальше...

Conventional quantum algorithms are not feasible for solving combinatorial optimization problems (COPs) with constraints in the operation time of quantum computers. To address this issue, researchers have developed a novel algorithm called post-processing variationally scheduled quantum algorithm. The novelty of this innovative algorithm lies in the use of a post-processing technique combined with variational scheduling to achieve high-quality solutions to COPs in a short time.

Annealing processors are crucial for solving combinatorial optimization problems. However, they face scalability challenges due to the complexity of required architecture. TUS researchers have now designed a scalable, fully-coupled processor with 4096 spins and parallel processing capabilities. It demonstrates superior performance and power efficiency compared to traditional devices. The research team aims to develop a 2050-level quantum computer computing system by 2030, potentially revolutionizing... Читать дальше...

Biologists use a novel method of simultaneous acoustic tagging to gain insights into the link between whale communication and behavior

A new study reveals how fire suppression ensures that wildfires will burn under extreme conditions at high severity, exacerbating the impacts of climate change and fuel accumulation.

A small-bird species, the Japanese tit (Parus minor), uses wing movements as a gesture to convey the message 'after you,' according to new research. When a mating pair arrives at their nest box with food, they will wait outside on perches. One will then often flutter its wings toward the other, apparently indicating for the latter to enter first. The researchers say that this discovery challenges the previous belief that gestural communication is prominent only in humans and great apes, significantly... Читать дальше...
