Is odor the secret to bats' sex appeal?

Odors come from very different parts of bats' bodies, from their heads and mouths to their wings or genitalia

When falling in love, humans often pay attention to looks. Many non-human animals also choose a sexual partner based on appearance. Male birds may sport flashy feathers to attract females, lionesses prefer lions with thicker manes and colorful male guppies with large spots attract the most females. But bats are active in the dark. How do they attract mates? Mariana Muñoz-Romo, a senior Latin American postdoctoral fellow at the Smithsonian Tropical Research Institute (STRI) and National Geographic explorer, pioneers research to understand the role of odors in bat mating behavior.

First DNA extracted from modern, ancient and fossil tropical shells

The next time you eat seafood, think about the long-term effects. Will consistently eating the biggest fish or the biggest conch, mean that only the smaller individuals will have a chance to reproduce?

In Wonderland, Alice drank a potion to shrink herself. In nature, some animal species shrink to escape the attention of human hunters, a process that takes from decades to millennia. To begin to understand the genetics of shrinking, scientists working at the Smithsonian Tropical Research Institute (STRI) in Panama successfully extracted DNA from marine shells. Their new technique will not only shed light on how animals from lizards to lemurs shrink, it will reveal many other stories hidden in shells.

Are eastern pacific corals climate change survivors?

A tech entrepreneur who dreamed of becoming a marine biologist teams up with STRI researchers and young Latin American biologists to find out if some coral reefs are more resilient than others

 

Coral reefs cover 1% of the Earth’s surface – but are home to 25% of the world’s marine species. Reefs are under threat from climate change, but a team of researchers from STRI has embarked on a four-year quest to solve a tantalizing mystery: why do some corals in the Tropical Eastern Pacific seem to be more resistant to the damaging effects of climate change than corals elsewhere? By unlocking the secrets of these “super-corals,” they hope to help rescue and restore coral reefs worldwide.

How larger brains can predict social behaviours

Team of researchers, co-led by IGC principal investigator Rui Oliveira, discovered that the size of the brain is important for complex social decision making

Eager to understand how the environment can impact animal cognitive performance, a team of researchers discovered that, in cleaner fish from the Great Barrier Reef, the size of the brain is important for complex social decision making. The study published in Nature Communications suggests that large forebrains (the forward-most portion of the brain) enable individuals to adapt better to local environmental conditions, important data to add to the study of coral reef ecosystems.

Sepsis: new evidence to understand and fight the disease

Study published in the journal Cell Host & Microbe reveals new mechanisms that confer resistance against sepsis and sheds light on key aspects of hominid evolution

Researchers discover that the loss of a specific molecule may explain how primates evolved to be able to resist to bacterial infections leading to sepsis. The study published in the prestigious scientific journal Cell Host & Microbe reveals that, in mice, the absence of this molecule (the α-Gal glycan) from the antibodies structure increases the ability to the same antibody to kill bacteria. This evolutionary advantage emerged with a cost, the reproductive decline. These findings shed light on key aspects of hominid evolution and reveal new mechanisms that confer resistance against sepsis, crucial to understand and fight the disease.

Male bats with high testosterone levels have large forearm crusts

Male Fringe-Lipped bats smear a sticky, odorous substance on their forearms. When this was discovered, researchers guessed that it might play a role in mating

Males may put a lot of effort into attracting females. Male peacocks flaunt eye-catching trains, but male bats, because they are active at night, may rely on females’ sense of smell to draw them in. Three years ago, Victoria Flores, a predoctoral fellow at the Smithsonian Tropical Research Institute (STRI) in Panama, discovered that male fringed-lipped bats often have a sweet-smelling, crusty substance on their forearms. Because only males had crusts and primarily exhibited these crusts during the putative reproductive season, Flores speculated that crusts might play a role in mating. Now Mariana Muñoz-Romo, postdoctoral fellow at STRI and National Geographic Explorer, and her colleagues have evidence to prove it.

As oceans warm and become more acidic and oxygen-poor, Smithsonian researchers asked how marine life on a Caribbean coral reef copes with changing conditions

“During my study, water temperatures on reefs in Bocas del Toro, Panama, reached an alarming high of almost 33 degrees C (or 91 degrees F), temperatures that would make most of us sweat or look for air conditioning—options not available to reef inhabitants,” said Noelle Lucey, post-doctoral fellow at the Smithsonian Tropical Research Institute (STRI).

The CoronaSurveys Project, among the finalists for the COVID-19 Symptom Data Challenge

Recognition of months of work studying the prevalence of coronavirus in real time

Over 150 researchers and 50 organisations participated in the call for proposals entitled the COVID-19 Symptom Data Challenge, sponsored by Facebook Data for Good, with the participation of Delphi Group-Carnegie Mellon University (CMU), the Joint Program on Survey Methodology-University of Maryland (UMD), the Duke Margolis Center for Health Policy, and Resolve to Save Lives, an initiative by Vital Strategies.


Organised by Catalyst @Health 2.0, on Wednesday the 16th the announcement was made that the award went to the project DeepOutbreak (Georgia Tech), during a ceremony which saw the participation of renowned people including Dr Tom Frieden (President and CEO of Resolve to Save Lives); Dr Mark McClellan (Director of the Duke-Margolis Center for Health Policy); Farzad Mostashari, CEO of Aledade; Kang-Xing Jin, Head of Health at Facebook, and specialist health and technology journalist Christina Farr (NBC). During the event, the finalists pointed out the most noteworthy issues from their research studies.


CoronaSurveys won 5000 dollars in recognition of its status as a finalist, thanks to the results obtained in recent months for the real-time collection, via simple anonymous surveys, of the number of COVID-19 cases in the world and innovations like collecting data on vaccination. Great collaborative work based on an indirect reporting method called Network Scale-up, which leads to extremely precise estimates from a moderate number of responses. The survey is available in 60 languages from countries round the world (150 of them regional), with data and estimates available for use by political leaders and the scientific community.


As pointed out by Antonio Fernández Anta, Research Professor at IMDEA Networks and project promoter since March 2020, along with an extensive team of university researchers and research centres: ‘Participation in Data Challenge has been a unique experience. On the one hand, it has obligated the CoronaSurveys team to start up a working line on prediction and early warning, which we hope will be extremely useful. On the other, it has let us give widespread visibility to the combination of obtaining indirect information and applying the Network Scale-up Method as a technique with many advantages for its application to public health.’

Smithsonian scientist clears up Panamanian urban legend

How did canal grass arrive in Panama? STRI staff scientist Kristin Saltonstall compared the DNA of sugar cane relatives from around the world to find out

Urban legends about the origins of canal grass in Panama abound, but the Smithsonian has new evidence that puts the question to rest. Canal grass is an invasive weed, native to Asia. Because its tiny seeds blow in the wind, it readily invades clearings and spreads to form impenetrable stands by budding from tillers and rhizomes. Once established, canal grass is challenging to eliminate. Fire burns the tops and stimulates the roots. Glassy hairs edging its leaf blades cut skin and dull machetes.

Early human landscape modifications discovered in Amazonia

No evidence of extensive savannah formations during the current Holocene period

In 2002 Professor Alceu Ranzi (Federal University of Acre) and Prof. Martti Parssinen (University of Helsinki) decided to form an international research team to study large geometric earthworks, called geoglyphs, at the Brazilian state of Acre in South-western Amazonia. Soon it appeared that a pre-colonial civilization unknown to international scholars built there geometric ceremonial centers and sophisticated road systems. This civilization flourished in the rainforest 2,000 years ago. The discovery supported Prof. William Balee´s (Tulane University) theory of early human impacts on the current Amazonian tropical forest composition that radically altered the notion of the pristine Amazon rainforest.
