These tiny frogs, known as pumpkin toadlets, live in the Brazilian Atlantic Forest and have fluorescent skeletons. For a new study published in Scientific Reports, scientists studied how this species mated, but when they placed one of these toads under UV lights, they discovered its bones were glowing. Moreover, after examining their anatomy, the group of experts found that these frogs can't hear their own mating calls because they lack a middle ear bone, so scientists concluded that the pumpkin toadlets use their fluorescent skeletons to communicate with each other.

The Trump administration moves a step forward into listing giraffes under the Endangered Species Act. For years, biologists across the country have warned that this species is at growing risk of extinction from habitat loss, poaching, and other threats. In 2017, environmental and conservation groups petitioned for the giraffes to be protected under this act, and after receiving no response from the government for two years, they sued this past December. At last, on Thursday morning, the US Fish and Wildlife Service determined there is substantial information that listing may be warranted for giraffes. Now, there will be a more in-depth review that could lead to giraffes being included in the Endangered Species Act.

Environmental activist group, Extinction Rebellion, protested in front of the London Stock Exchange and banks across the city. For weeks, the activist group has refused to stand down as it continues to cause civil disruption in London; their goal is to get the government's attention so that new laws regarding climate change can be put in place. In the latest protest, Extinction Rebellion targeted the financial industry because they're not telling the truth and they're secretly funding climate and ecological destruction. Moreover, the environmental advocates reaffirmed that their goal was for the people working in this sector to understand the severe impact that their actions will have in the future of our planet.

Thousands of emperor penguin chicks disappeared in Antarctica in 2016, and now its population has suffered a steep decline. After experts from the British Antarctic Survey looked at some satellite images, they were able to determine that the piece of ice where eggs used to hatch melted three years ago melted. Emperor penguins need sea-ice that remains solid for most of the year while they find mates, breed, and raise their chicks. However, no penguins have returned to the hatching area since the ice vanished. New studies show emperor penguins in Antarctica have disappeared from the Brunt Ice Shelf, and if sea-ice continues melting as computers predict, almost 70% of its population will in less than one hundred years.

On Mars, in an area known as Cerberus Fossae, NASA was able to capture an image of a landslide. This area, according to experts from the University of Arizona, is the youngest fault system on Mars described as a steep-sided set of troughs cutting volcanic plains to the east of Elysium Mons. Scientists were able to capture this image in Cerberus Fossae, thanks to the HiRISE camera on the Mars Reconnaissance Orbiter that has been orbiting Mars for more than a decade. Researchers across the world are fascinated because this news comes at the same time that scientists were able to detect the first marsquake.

In 2018, the world lost an area of rainforest equivalent to the size of England. A new study by scientists from the Global Forest Watch has revealed that humanity destroyed 30 million acres of tropical forest last year. Moreover, the scientists were able to determine that the previous year's loss has been the third largest decline since global satellite data became available in 2001. The most significant rainforest loss occurred in Brazil, the Democratic Republic of Congo, Indonesia, Colombia, and Bolivia. Forests absorb about 30% of human-made greenhouse gas emissions, just over 11 billion tonnes of CO2 a year; losing rainforests means more carbon is released into the atmosphere and fewer trees will be left to absorb greenhouse gas emissions.

New measurements from NASA's Hubble Space Telescope confirm the universe is expanding about nine percent faster than expected. Scientists used the Hubble's calculations, and another set of observations, made by the Araucaria Project to have a better understanding of the cosmic distance ladder, which is used to determine distances within the Universe, and how fast the cosmos expands over time. However, their calculations were different from the early universe expansion observations made by the European Space Agency. The team of professionals will continue working on reducing the disparity of the estimates and have admitted that new physics might be necessary to determine how fast the universe is expanding.

A video shows just how hard it is to walk after coming back from a trip to outer space. A NASA astronaut, Drew Feustel, spent almost 200 days in microgravity at the International Space Station, and when he came back to Earth, he posted a video where he can be seen stumbling as he attempts to walk. Since humans weren't made to withstand microgravity, they suffer from muscles atrophy and loss of bone density while in space; and once astronauts are back on Earth, they struggle to walk due to these factors and a severe case of vertigo. At the moment, astronauts in the ISS have to exercise two hours a day to fight against the effects of microgravity.

While some cities across the US are banning single-use plastics, The governor of Oklahoma has approved a ban on taxing plastic bags. The proposal for this bill came after officials in Norman considered imposing a 5-cent tax on plastic bags to fight pollution. However, this idea was halted now that the legislation to ban this tax has been approved in the Senate. Retailers and container manufacturers supported this bill since the taxing could have increased the cost of groceries and packaged foods.

A new study has determined that seven of the ten most polluted cities in the US are in California. These findings come after the American Lung Association released a new report on Wednesday that revealed emissions from cars and trucks are the top source of air pollution. Moreover, last year's wildfires increased particle pollution levels across the state, making it difficult for many people to breathe. Clean air advocates are pushing for changes across this state such as reducing the amount of vegetation that causes wildfires and using more efficient ways of transportation, which would contribute to reducing the levels of air pollution.

Flower poppies bloomed in the Santa Monica Mountains after last year's wildfire scorched the area. This type of flower blooms after a major fire has occurred, and since one year has passed since the Woolsey fire swept through Southern California, park rangers were expecting to see them bloom. Ana Beatriz Cholo works in the Santa Monica Mountains, and recently, she decided to set out on an excursion to see if she could find these poppies. Early this week, Cholo found the rare Papaver californicum, commonly known as fire poppies which come in orange, red and brick red. Moreover, these flowers are fleeting since they bloom for a day or two and wait until another blaze comes to bloom again.

A group of Irish zoologists has uncovered two new bird species in the Wakatobi Archipelago of Sulawesi, Indonesia. For the past two decades, zoologists at Trinity College Dublin have been working with the Halu Oleo University in cataloging Sulawesi's unique biodiversity. In their work, the researchers have used modern techniques to analyze species separation by comparing animals based on genetic factors, body size, and differences in the birds' song. The Zoological Journal of the Linnean Society published that the researchers had discovered two new bird species, the Wakatobi white-eye, and the Wangi-Wangi white-eye. Zoologists believe this discovery could lead them to have a better understanding of how new species emerge.

The founder of Bee Saviour Behaviour, Dan Harris, was worried about how bees run out of energy due to their fast metabolism and die. Although there is a simple way to help them by giving them a sugary solution to drink, this technique is only used in farms. That's why Harris decided to create a method that people could use to help bees wherever they are. For three years, Harris worked to develop a saving kit that consists of a recycled bank card with three holes containing water and pure fondant sugar. He has started a crowdfunding campaign for the manufacturing of these kits so that more cards can be made in time for the summer.

German scientists have 3D printed see-through human organs that could be transplanted into the body in the future. A team of researchers at the University in Munich developed a technique that uses a solvent to make organs transparent; afterward, the organs get scanned by a microscope that allows researchers to capture the entire structure, including the blood vessels and every single cell. Then, after completing these steps, the data is loaded to a 3D printer with stem cells which act as 'ink' and are injected into the correct position to make the organ function. In the past, 3D-printed organs lacked detailed cellular structures, meaning the work of these scientists is a step forward for 3D printing in the medical field.

The government has revoked hunting licenses and now killing pest birds is illegal in England. In the past, the government had issued a list of 16 birds it was permissible to kill under general license so that farmers could protect their livestock. In the meantime, if people want to shoot these 'pest' birds, they must apply for an individual permit. The decision comes after the Wild Justice activist group pushed to change the legislation regarding pest birds killings and to execute proper wildlife conservation laws in the UK. Farmers have complained about this measure saying it couldn't have come at a worse time, and they expect to be consulted now that a better licensing system is being designed.
