Primary tropical forests are best but regrowing forests are also vital to biodiversity

Even after 40 years of recovery, secondary forests remain species and carbon-poor compared to undisturbed primary forests, a new study reveals

Even after 40 years of recovery, secondary forests remain species and carbon-poor compared to undisturbed primary forests, a new study reveals. However these secondary forests - forests regrowing in previously deforested areas - are still vitally important to biodiversity conservation and carbon storage, argue scientists.

Genes key to identifying drug resistant parasites in Brazil

Leishmaniasis is a parasitic disease transmitted to humans by the bite of the infected female sandfly. With 50,000 to 90,000 new cases worldwide each year

Researchers at the University of York have identified genes in a parasite that could help clinicians predict drug treatment outcomes for patients with visceral leishmaniasis in Brazil. The findings could lead to a new prognostic test that can predict which patients will respond well to drug treatment and which patients need alternative solutions.

When Is a Nova Not a ‘Nova’? When a White Dwarf and a Brown Dwarf Collide

An international team of astronomers found evidence that a white dwarf and a brown dwarf

Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers found evidence that a white dwarf(the elderly remains of a star like the Sun) and a brown dwarf(a failed star without the mass to sustain nuclear fusion) collided in a short-lived blaze of glory that was witnessed on Earth in 1670 asNovasub Capite Cygni (a New Star below the Head of the Swan), which is now known as CK Vulpeculae.

Amazon rainforest conservation victories spill losses to neighbors

In the state of Tocantins alone the conversion to agricultural land increased from 465 square miles to 3,067 square miles from 2007 to 2015

New research suggests that protecting the Amazon rainforest from deforestation may just be shifting the damage to a less renowned neighbor. The unintended consequences are profound.

The dog, when treated with insecticide, is man's best friend

A model predicts that treating dogs in a community with a systemic insecticide can reduce visceral leishmaniasis transmission in Brazil

Treating dogs at a community level with systemic insecticide could considerably reduce the transmission of visceral leishmaniasis in Brazil, according to a modelling study led by ISGlobal, an institution supported by "la Caixa" Foundation. The results, published in PLOS Neglected Tropical Diseases, will help define which kind of insecticide is needed and how to apply it to achieve maximum effectiveness.

The constructive role of noise

International research with the participation of the UC3M

Noise can induce spatial and temporal order in non-linear systems, which helps to detect and amplify weak external signals that are difficult to detect by conventional amplifiers, according to an international team composed of researchers from Germany, China and Spain in which the Universidad Carlos III de Madrid (UC3M) is a participant. The work, published in two articles of the Physical Review Letters magazine, explains that this effect can be used in the decoding and in the creation of extremely weak signals, without the need for a reference signal and in a much shorter time than with a conventional amplifier.

Newly discovered hummingbird species already critically endangered

The Blue-throated Hillstar is found only along bush-lined creeks in an area of about 100 square kilometers, and the researchers estimate there are no more than 750 individuals

In 2017, researchers working in the Ecuadorian Andes stumbled across a previously unknown species of hummingbird--but as documented in a new study published in The Auk: Ornithological Advances, its small range, specialized habitat, and threats from human activity mean the newly described Blue-throated Hillstar is likely already critically endangered.

California Academy of Sciences discovers new species of dazzling, neon-colored fish

Named for Aphrodite, Greek goddess of love and beauty, a new species of fish enchants Academy scientists; only known home is remote Brazilian archipelago

On a recent expedition to the remote Brazilian archipelago of St. Paul's Rocks, a new species of reef fish--striped a vivid pink and yellow--enchanted its diving discoverers from the California Academy of Sciences. First spotted at a depth of 400 feet beneath the ocean's surface, this cryptic fish inhabits rocky crevices of twilight zone reefs and is found nowhere else in the world. Upon discovery, the deep-diving team was so captivated by their finned find that they didn't notice a massive sixgill shark hovering above them in an exciting moment captured on camera. The new fish description published today in Zookeys.

Violence in pre-columbian Panama exaggerated, new study shows

An oft-cited publication said a pre-Colombian archaeological site in Panama showed signs of extreme violence. A new review of the evidence strongly suggests that the interpretation was wrong

Buried alive. Butchered. Decapitated. Hacked. Mutilated. Killed. Archaeologist Samuel K. Lothrop did not obfuscate when describing what he thought had happened to the 220 bodies his expedition excavated from Panama’s Playa Venado site in 1951. The only problem is that Lothrop likely got it wrong. A new evaluation of the site’s remains by Smithsonian archaeologists revealed no signs of trauma at or near time of death. The burial site likely tells a more culturally nuanced story.

Hookworms employ live fast/die young strategy in fur seal pup hosts

Researchers believe the hookworms' short lifespans have evolved to synchronize with the fur seals' reproductive cycles

Hookworms exploit a live fast/die young strategy in their South American fur seal pup hosts, report Morris Animal Foundation-funded researchers at the University of Georgia. As a result, they often kill their host, rather than finding a happy equilibrium. Scientists are concerned that this type of hookworm infection could eventually pose a risk to critically endangered populations of fur seals.

Birds retreating from climate change and deforestation in Honduras cloud forests

Bird diversity shifts upslope in tropical mountainous terrain

The cloud forests of Honduras can seem like an otherworldly place, where the trees are thick with life that takes in water straight from the air around it, and the soundscape is littered with the calls of animals singing back and forth. Otherworldly, yes, but scientists have found that the cloud forests are not immune to very down-to-earth problems of climate change and deforestation. A 10-year study of bird populations in Cusuco National Park, Honduras, shows that the peak of bird diversity in this mountainous park is moving higher in elevation. Additional land protection, unfortunately, may not be enough to reverse the trend, driven in part by globally rising temperatures. The study is published in Biotropica.

Old species learn new tricks…very slowly

Aaron O’Dea and colleagues show that when the Caribbean was cut off from the Pacific by the rise of the Panama land bridge, evolutionarily old species took longer to expand into new habitats than evolutionarily younger species did

A quick look at the fossil record shows that no species lasts forever. On average, most species exist for around a million years, although some species persist for much longer. A new study published in Scientific Reports from paleontologists at the Smithsonian Tropical Research Institute in Panama shows that young species can take advantage of new opportunities more easily than older species: a hint that perhaps older species are bound to an established way of life.
