West Antarctica glacier is disintegrating faster than expected


New Delhi: The Thwaites Glacier in West Antarctica is “suspended by its fingernails”, according to scientists who mapped a critical area of ​​the seafloor in front of the glacier in high resolution to understand how fast it is retreating.

This massive ice flow is already in a phase of rapid retreat, prompting widespread concern about how quickly it could give its ice back to the ocean.

Thwaites’ retreat could raise sea levels by 3 to 10 feet.

Researchers from the University of South Florida have identified geological features that are new to science. These also give insight into Thwaites’ future.

The team documented more than 160 parallel ridges that were created when the leading edge of the glacier retreated and swayed up and down with the daily tides.

The team said Thwaites will likely go through big changes over the next few years. Read more

A new math equation could transform medical procedures

Scientists have developed a mathematical equation that describes how microscopic particles move, which could transform medical procedures, natural gas extraction and plastic packaging production in the future.

The new equation is described as revolutionary by scientists at the University of Bristol. It describes for the very first time the diffusive motion of particles through a permeable material.

It comes a century after world-renowned physicists Albert Einstein and Marian von Smoluchowski derived the first diffusion equation and marks a significant advance in representing motion for a wide range of entities, from microscopic particles and natural organisms to artificial devices.

Until now, scientists studying particle motion through porous materials such as biological tissues, polymers, various rocks and sponges have had to rely on approximations or incomplete insights.

The new equations may have applications in a wide range of contexts, including health, energy and the food industry. Read more

A new species of dinosaur identified in Germany

German scientists have discovered a new species of herbivorous dinosaur that lived around 203 to 211 million years ago in the region now known as the Swabian Jura.

The new species, named Tuebingosaurus maierfritzorumbears similarities to the large, long-necked dinosaurs known as sauropods. It was identified when previously known dinosaur bones were re-examined by paleontologists from the University of Tübingen.

Fossils, which are part of Tubingenfrom the paleontological collection, were previously interpreted as Plateosaurids remains.

Most of the fossils come from a quarry near Trossingen on the edge of the Swabian Jura, where many dinosaur bones found since the 19th century have often been classified as Plateosaurus.

When they reanalyzed a skeleton discovered in Trossingen in 1922, consisting mostly of the back of the body, the team established that many bones were not the same as a typical skeleton. Plateosaurus.

For example, the partial skeleton exhibited, among other derived characters, wider and more strongly built hips with fused sacral vertebrae as well as unusually large and robust long bones – both characteristics involved locomotion on four legs.

After a thorough comparison of all anatomical features, scientists reclassified the partial skeleton from Trossingen into the dinosaur tree of life and established that they had discovered a previously unknown species and genus.

The study was published in the journal Vertebrate Zoology. Read more

Solar Orbiter gets a detailed look at the coronal mass ejection

A large coronal mass ejection fired from the Sun towards Venus and hit the ESA-NASA solar orbiter, revealing that the solar storm is changing the space environment.

The data returned by the orbiter reveals why it is important to monitor space weather and its effects on celestial bodies and spacecraft.

Coronal mass ejections are large expulsions of plasma and magnetic field from the solar corona.

There were no adverse effects on the spacecraft as the solar observatory is designed to withstand and measure violent outbursts from the sun.

Coronal Mass Ejections Stripped Venus’ Atmosphere of Gases — one of the reasons why the planet is considered unfit for life.

Solar Orbiter is a quarter into its decade-long mission to observe the Sun up close and peek at its mysterious poles. Its orbit was chosen to be in close resonance with Venus, meaning it returns close to the planet every few orbits to use its gravity to alter or tilt its orbit.

Data transmitted to the house since Solar Orbiter encountered the solar storm shows how its local environment has changed as the large coronal mass ejection passed.

While some instruments had to be turned off during its close approach to Venus, in order to protect them from the stray light reflected by the planet’s surface, the “in situ” instruments of Solar Orbiter remained on, recording among other things an increase solar energetic particles. . Read more
