Interested in nature, Valerie Varnuska of Westbury, NY, spends some of her time exploring outdoors. Given her interest, she enjoys hiking and protecting the environment around her. To this end, Valerie Varnuska stays abreast of news relating to nature topics. In September 2021, "Nature," a weekly international journal promoting science and technology, released a new analysis of the carbon dioxide emissions from the bush fires in southeastern Australia. These bushfires burned through late 2019 to early 2020 and covered over 74,000 square kilometers of eucalyptus forests in the area. In total, the fires burned an area larger than Sri Lanka. Global databases and satellite data results show estimates that the fires had released about 275 million tons of carbon dioxide. However, a new analysis states this amount was actually 715 million tons, which is over double the estimated amount and more than 80 times the average amount released by fires in southeast Australia. Despite the m...

   Valerie Varnuska is from the Westbury, NY community and enjoys excursions in nature in her free time. One aspect of this for Valerie Varnuska involves learning about the behavior of bats in the wild. A study published in Nature focuses on the repeated vocalizations young bats make, which help them develop the ability to make sounds they carry into adulthood. Led by a Berlin Museum of Natural History animal behavioral ecologist, the study involved recording more than 200 “babbling bouts” by greater sac-winged bats in Panama and Costa Rica. Ultrasonic equipment was employed to catch individual syllables contained within bat pups’ high-pitched squeals. Within this babble, researchers identified a majority of the 25 syllables that adult bats use for tasks such as seeking food through echolocation and navigating airspace, as well as for courtship. Despite significant differences in how humans use language and bats employ vocalizations, researchers linked the pups’ babble to th...

Valerie Varnuska from the Westbury, NY area, has a longstanding interest in the outdoors. One aspect of the natural world that Valerie Varnuska appreciates is the health benefits such explorations bring. In today’s urbanized, digitally connected world, access to natural experiences has diminished for many, with this lack of natural stimuli characterized as “nature-deficit-disorder.” Unfortunately, people are increasingly cut off from a vital aspect of personal development that has served societies well for millennia. This begins with childhood habits and experiences: a Psychology Today article reports that unstructured outside play has decreased by one-fourth since 1981. The effect is felt in attention deficits, obesity, emotional instability, and a diminished reliance on the full range of senses. Faced with such lost opportunities, the imperative of conserving nature is not simply about preserving biological diversity and clean air and water, but preserving something vital within ou...

Based in the Westbury, New York area, Valerie Varnuska enjoys learning about the natural environment surrounding her by exploring the outdoors and studying the night sky regularly. Valerie Varnuska follows the latest research studies in the field of paleontology. A recent research study recently published in the Journal of Mammalian Evolution describes the discovery of a newly identified giant saber-tooth that is presumed to have inhabited North America between five and nine million years ago. As part of the investigation, scientists compared uncategorized and already classified fossil specimens of forearms and teeth belonging to giant saber-tooths worldwide. While comparing fossils, they discovered numerous specimens from giant felines in museums across North America. Subsequently, they concluded the existence of a newly found ancient relative to the saber-tooth animal that lived in North America. Named Machairodus lahayishupup, the primitive mammal is thought to have weighed betwee...

Valerie Varnuska is a Westbury, New York area resident who often spends time exploring her surrounding natural environment. Fascinated with observing elements of the evening sky, Valerie Varnuska enjoys increasing her knowledge of astronomy. Astronomical researchers at NASA learned that Mars is quite possibly seismically active. Two quakes measuring magnitudes of 3.1 and 3.3 on the Richter scale were recorded by NASA’s InSight lander’s Seismic Experiment for Interior Structure (SEIS) instrument in March of 2021. The quakes occurred in Cerberus Fossae, a volcanic region of the planet that is the origin of two previous large quakes that occurred in February of 2020 and measured magnitudes of 3.6 and 3.5 on the Richter scale. Scientists aren’t certain if the quakes are being caused by current volcanic activity or if they are due to passive cooling, which occurs as the planet’s temperature drops. As the planet cools, this causes the crust to contract and crack. Researchers will continue ...

Based in Westbury, New York, Valerie Varnuska enjoys spending time in nature. Valerie Varnuska is particularly interested in the night sky and discoveries in the field of astronomy. Recently, astronomers observed what might be a previously undiscovered planet . Using the Very Large Telescope, or VLT, operated by the European Southern Observatory from Cerro Paranal in Chile’s Atacama Desert, scientists observed a bright spot near the star Alpha Centauri A. The telescope was aided by an instrument that blocked out much of the light from the two Alpha Centauri stars, making the detection of orbiting objects easier. After 100 hours of infrared observations in May and June 2019, astronomers acknowledge the spot could be a planet, but it also could be dust, asteroids, or a glitch in the machine. If it is a planet, it is likely about the size of Neptune, or four times the size of Earth, and lies in Alpha Centauri A’s habitable zone. To further determine whether the object is a planet, resear...

If you usually go to the gym, try exercising in a park or doing your workout in the backyard. If you normally visit a coffeeshop, opt for patio seating rather than indoor seating. You can even perform everyday tasks such as sorting the mail outdoors. 3. Schedule it. If you have free time on the weekends, plan something outdoors. Search for a beginner-friendly hike or nat...

An enthusiast of the natural world, Westbury, New York, resident Valerie Varnuska enjoys walking outdoors, observing the stars, and learning about scientific discoveries. Valerie Varnuska possesses an interest in several areas of science, including conservation. To preserve biodiversity, conservationists have put out a call to action for governments around the world to implement policies that protect threatened and endangered species. Initiatives put in place in nations across Asia have resulted in the successful comeback of several tiger species. When conservation efforts were first enacted in 2010, the wild tiger population in Asia dwindled to less than two dozen in some regions. Thirteen countries, including India, Nepal, and China, pledged to double the number of tigers by 2022. As of 2020, the tiger population grew from 3,200 to 3,900. The rise is attributed to an increased focus on preserving the tiger’s natural habitat. India alone has established more than 40 reserves since 197...

In addition to her interests in volunteer work, travel, and new recipes, Valerie Varnuska of Westbury, New York, maintains an interest in diverse scientific topics. Valerie Varnuska is especially fascinated by the fields of astronomy and paleontology. After the discovery of ancient monkey teeth in Peru in 2015, paleontologists have hypothesized that these small primates   traveled from Africa to South America on large, floating landmasses that broke away from the mainland more than 30 million years ago. For many years, it was believed that this migration occurred only once. However, molars from a different but contemporary primate species were unearthed in 2020. This evidence suggests that two separate groups of monkeys made their way across the Atlantic Ocean. Scientists believe that the monkeys were able to make the perilous journey because of their small size. The primates sustained themselves on the limited food and water on the landmass until they reached the new continent. Af...

Valerie Varnuska of Westbury, New York enjoys exploring the natural world. Some of Valerie Varnuska’s areas of interest are the links between exposure to nature and health. For centuries, humans have had traditions of gaining a renewed sense of wellness and purpose from interactions with nature . This practice was confirmed in a 2019 study published in the International Journal of Environmental Health Research indicating that as little as 20 minutes spent in a park can have a measurably positive impact. The researchers at the University of Alabama at Birmingham took a survey of nearly 100 adults who indicated that they visited urban parks in the local area. These participants answered a set of questions covering mood and life satisfaction before and after visits to the park. These were used to plot a subjective well-being score, with 55 the highest value. At the same time, participants wore fitness trackers that measured their activity levels while in the park. They were not given ...

Longtime Westbury, NY, resident Valerie Varnuska loves learning about the natural world. To this end, Valerie Varnuska is fascinated by sciences such as geology and paleontology. It’s well-established that numerous animals, from humans to insects, feature a bilaterian body plan. This means that they have a back, stomach, head, and tail that are organized as mirror images of one another. Due to this orientation, organisms are capable of moving in a purposeful way, thus establishing the development of bilateral symmetry as an important stepping stone in animals’ evolutionary history. The oldest animals who displayed this type of bilateral symmetry are called bilaterians . Based on studies of modern animals, evolutionary biologists believe these bilaterians have basic sensory organs and are relatively simple creatures. However, fossilized remains of the animal were difficult to find. Rather, paleontologists have exclusively studied fossilized burrows created in Ediacaran-period de...

A lifelong resident of Westbury, NY, Valerie Varnuska enjoys exploring the nature trails near her home. In addition, Valerie Varnuska has an interest in astronomy and frequently takes time to view the night skies. Astronomers recently made a new discovery, based on data from NASA’s Chandra X-ray Observatory, about what happens to stars. Looking at stars in the Fornax Cluster about 60 million light years from Earth, astronomers found that some stars have the potential to be ejected from their original galaxy. The Chandra X-ray Observatory recorded data from the Fornax Cluster over a 16-year period. Astronomers noted that the nonsymmetrical recoil blast from a dying supernova creates enough force to knock the resulting neutron stars out of their home galaxy, sometimes even taking companion stars in their orbit with them.  The research team spotted more than two dozen potential star pairs that were likely ejected from their galaxies. The findings were published in the May 2019 ed...

A member of the Westbury, NY, community, Valerie Varnuska is a science enthusiast. Valerie Varnuska maintains a particular interest in the field of paleontology. In addition to dinosaurs and other ancient animals and plants, paleontologists study the fossil record for clues about the evolution of the human species. In January 2019, a new report shed some light on an unexpected discovery made by researchers last summer. In the discovery, reported in August 2018, scientists announced that they had identified an ancient human specimen that appeared to be a hybrid between two distinct hominid species, Neanderthals and Denisovans. The announcement, the first evidence that these early species had ever commingled, sent ripples through the scientific community. A more recent announcement suggests that this hybrid may not have been a unique case. Using artificial intelligence and advanced statistical methods, scientists from several institutes examined the genome of a group of Asian people a...
