Study results on whale song suggest that the consensus response to the question of why humpbacks sing is wrong. The whales don’t sing to attract a mate (reproductive hypothesis), according to Eduardo Mercado III, a University at Buffalo professor of psychology. They’re singing to find other whales (sonar hypothesis), using mechanisms within their songs that may be comparable to those at work in the eyes of land animals as they examine their environment. “[This isn’t a] feather in the sonar hypothesis cap? It’s more like an arrow through the chest of the reproductive display hypothesis,” says Mercado.

Snow monkeys living in one of the world’s coldest regions survive by ‘going fishing’ – scooping live animals, including brown trout, out of Japanese rivers and eating them to stay alive, a new study reveals.

The Stifterverband and the German National Academy of Sciences Leopoldina have honoured haematologist, oncologist and immunologist Prof. Dr. Christoph Huber with a special edition of the Carl-Friedrich-von-Weizsäcker Prize. The award recognises Prof. Huber's contribution to research and knowledge translation in the field of cancer immunotherapy. His research provided an important foundation for the development of an mRNA vaccine against COVID-19, which proved such a vital tool for managing the pandemic. The Carl-Friedrich-von-Weizsäcker-Prize is endowed with 50,000 euros and honours researchers who have made a valuable scientific contribution to resolving key societal challenges.
A group led by Prof. Ke Yang of Peking University Cancer Hospital released real-world evidence evaluating outcomes of minimally invasive esophagectomy (MIE) compared with open esophagectomy (OE) in localized esophageal squamous cell carcinoma (ESCC) patients.

New research finds that Arctic krill have a biological response to changes in light. When it is lightest in the Arctic polar night, usually around the middle of the day known as midday twilight, the krill know to swim down to the bottom in order to hide from predators. When it is darkest in the Arctic polar night, that’s when they swim to the surface in search of bioluminescent food.

Biochemistry: Fundamentals and Bioenergetics is based on progressive experimental achievements of biochemists and biologists, biochemical information is updated day by day and documented in the form of a book. Biochemistry is continuously and steadily progressing at the laboratory level to life sciences. This textbook mainly aims to fulfill the requirement of undergraduates, postgraduates and research students having strong chemistry background with an ambition to enter into the biochemistry field. It is also helpful to instructors to get updates related to the field of biochemical sciences with little effort. The topics are explained, ranging from basics to a detailed knowledge in the area of biochemistry. To enable students to grasp the key points of chapters, keynotes have been included and a brief summary is given at the end of chapters. The editors and authors confirms that this book content has no conflict of interest.
The Food and Agriculture Organization (FAO) estimates that 25% of global food crops are contaminated with different types of fungal toxins, such as aflatoxins, highly toxic and carcinogenic substances produced by certain species of the fungus Aspergillus. New research published in Plant Disease reveals a deeper understanding of how members of this same fungus species can be used to reduce aflatoxins in crops.

The 15th volume of Advances in Organic Synthesis presents recent exciting developments in synthetic organic chemistry. The chapters are written by authorities in the field. The topics include a review of molecular halogens and Nhalamines in the context of their applications as acid- and metal-free catalysts, recent fluorination methods involving phase transfer catalysts, synthesis and applications of small fluorescent molecules, achievements in the synthesis of aromatic five-membered heterocycles containing one heteroatom, and lastly, a discussion about triazole synthesis under green conditions in basic ionic liquids.
University of Central Florida researchers have developed a device that detects viruses like COVID-19 in the body as fast as and more accurately than current, commonly used rapid detection tests. The optical sensor uses nanotechnology to accurately identify viruses in seconds from blood samples. Researchers say the device can tell with 95% percent accuracy if someone has a virus.

Chemical modification of solid surfaces by the use of additives is extremely important for a large variety of applications. For this reason, the book “Chemical modification of solid surfaces by the use of additive” summarizes these uses and gives an overview of recent developments of these syntheses and applications in this field.
Researchers have developed microbubbles to acoustically detect blood oxygen levels, since the microbubble shells are altered by structural hemoglobin changes in response to oxygen. The gas filling of the microbubbles causes them to oscillate and vibrate when ultrasound is applied, scattering energy and generating an acoustic response that can be detected by a clinical ultrasound scanner. Preliminary results show a strong correlation between oxygen concentration and the acoustic bubble response.
