Whales are recovering from near extinction, but industrial fishing around Antarctica competes for their sole food source
The Southern Ocean encircling Antarctica is the world's largest feeding ground for baleen whales—species like humpbacks that filter tiny organisms from seawater for food. In the 20th century, whalers killed roughly 2 million large whales in the Sou.....»»
Opinion: Researchers don"t take enough account of variation in biology—doing so could unlock new understanding
The natural world is filled with variety. Ecological systems can look very different in different parts of the Earth. Every species has genetic variation, which means individuals can look and behave very differently. Diseases can affect people differ.....»»
Researchers sequence the genome of the spur-thighed tortoise
Like many threatened land turtle species, the spur-thighed tortoise had no complete genome. Now for the first time, researchers from the Ecology departments at Miguel Hernández University of Elche (UMH) and the University of Alicante (UA) have succe.....»»
How viruses move through insects for transmission of diseases
Viruses are master parasites that have adapted to infect many host species. Some viruses even use multiple hosts to spread their infections—such as arboviruses that use insects to move their infections to mammalian hosts like humans. Understanding.....»»
Iron-doped carbon-based nanoparticles boost cancer treatment with enhanced precision and safety
Recently, a collaborative research team led by Prof. Wang Hui and Prof. Qian Junchao from Hefei Institutes of Physical Science of the Chinese Academy of Sciences designed a catalytically active, photoresponsive, Fe-doped carbon nanoparticle (FDCN) fo.....»»
Genetic analysis reveals new giant fanged frog species in Philippines that is nearly identical to even larger species
Researchers from the University of Kansas have published findings in the journal Ichthyology & Herpetology describing a new species of fanged frog, named Limnonectes cassiopeia, from the Philippine island of Luzon......»»
The case for adding iron to the ocean for carbon dioxide removal
While the urgent reduction of carbon dioxide (CO2) and other greenhouse gas emissions is needed as the primary activity to curb climate change, there is broad agreement for the need to remove CO2 already in the atmosphere. Given its outsized role in.....»»
Farming at the edges of nature reserves is helping exotic species invade New Zealand, finds study
Native shrublands were once common across the Canterbury Plains, but over time, conversion of land to other uses, including irrigated pasture, has contributed to their gradual decline. Now, a new study by scientists at Manaaki Whenua—Landcare Resea.....»»
Video evidence: Japanese eels escape from their predator"s stomach
Many prey species have defensive tactics to escape being eaten by their would-be predators. But a study published in Current Biology on September 9, 2024 has taken it to another level by offering the first video evidence of juvenile Japanese eels esc.....»»
Why do materials get stronger when they are deformed? Research sheds light on universal mechanisms of work hardening
The earliest blacksmiths in the Bronze and Iron Ages figured out that when they deformed metal through bending or hammering, it became stronger. This process, known as work or strain hardening, is still used widely in metallurgy and manufacturing tod.....»»
To save its tigers, India has relocated thousands of people—it could enlist their help instead
British colonialism turned India's tigers into trophies. Between 1860 and 1950, more than 65,000 were shot for their skins. The fortunes of the Bengal tiger, one of Earth's biggest species of big cat, did not markedly improve post-independence. The h.....»»
Bunyip birds and brolgas: How can we better protect species important to Indigenous people?
Kamilaroi Country lies in far northwest New South Wales, past Tamworth and crossing over the Queensland border. Here, the bunyip bird (Australasian bittern, Botaurus poiciloptilus), and the brolga (Grus rubicunda or burraalga in Kamilaroi) have been.....»»
Protecting just 0.7% of world"s land could help save a third of unique and endangered species
Conservation efforts directed towards just 0.7% of the world's land mass could help protect one third of the world's threatened and unique tetrapod (four-limbed vertebrate) species, new research by Imperial College London, On the Edge, and ZSL has sh.....»»
