Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA).

NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of Typhoon Hagupit in the Northwestern Pacific Ocean that showed the development of an eye as it quickly intensified. Imagery also showed a thick band of thunderstorms that resembled a giant tail, spiraling into the powerful storm.

When her South Carolina high school went online this spring, Maya Green struggled through the same emotions as many of her fellow seniors: She missed her friends. Her online assignments were too easy. She struggled to stay focused.

Tropical Storm Isaias was set to regain hurricane strength Monday before slamming into the US eastern seaboard, bringing life-threatening storm surges to North and South Carolina.

It may be one of the most recognisable symbols of conservation, but efforts to protect the giant panda have failed to safeguard large mammals sharing its habitats, according to research published Monday showing dramatic declines of leopards and other predators.

Virgin Orbit said Monday it has determined what caused the failure of its debut rocket launch and is working toward a second flight that will carry small satellites for NASA.

Whether in flood early-warning systems or in agriculture—rainfall measurements are of great importance. However, there is a lack of accurate data for many regions in the world due to the fact that comprehensive measurements have so far been too expensive. This could change with a new method that has just passed its practical test. Researchers at KIT (Karlsruhe Institute of Technology) and the...

Researchers from Frankfurt and Tübingen say the skull of a very large crane found at the Hammerschmiede fossil site in Allgäu, Bavaria, is more than eleven million years old. It is the earliest evidence of such a large crane in Europe, the paleontologists say. The fossil most closely resembles the skull of today's long-beaked Siberian crane, according to Gerald Mayr of the Senckenberg Research...

A half-century of controversy over two popular bird species may have finally come to an end. In one corner: the Bullock's Oriole, found in the western half of North America. In the other corner: the Baltimore Oriole, breeding in the eastern half. Where their ranges meet in the Great Plains, the two mix freely and produce apparently healthy hybrid offspring. But according to scientists from the...

CABI scientists have conducted research which is calling for an urgent integrated management strategy, including biological control, to fight the invasive weed Mimosa diplotricha which is threatening livelihoods in eastern and southern Africa

NASA's Lucy mission, led by Southwest Research Institute (SwRI), has achieved an important milestone by passing its System Integration Review and clearing the way for spacecraft assembly. This NASA Discovery Program class mission will be the first to explore Jupiter's Trojan asteroids, ancient small bodies that share an orbit with Jupiter and hold important insights to understanding the early...

Despite decades of positive messaging to encourage women and girls to pursue education tracks and careers in STEM, women continue to fall far below their male counterparts in these fields. A new study at Carnegie Mellon University examined 25 languages to explore the gender stereotypes in language that undermine efforts to support equality across STEM career paths. The results are available in the...

When two neutron stars slam together, the result is sometimes a black hole that swallows all but the gravitational evidence of the collision. However, in a series of simulations, an international team of researchers including a Penn State scientist determined that these typically quiet—at least in terms of radiation we can detect on Earth—collisions can sometimes be far noisier.

Despite enormous efforts to advance traditional pharmacology approaches, more than three quarters of all human proteins remain beyond the reach of therapeutic development. Targeted protein degradation (TPD) is a novel approach that could overcome this and other limitations, and thus represents a promising therapeutic strategy. TPD is based on small molecules, generally called 'degraders,' which...

In the human body, proteins sometimes occur in fibrillar aggregates called amyloids. Although certain amyloids are known to have a biological function, amyloid formation is often associated with pathologies, including Alzheimer's and Parkinson's diseases. Understanding how exactly amyloid fibrils form is crucial for gaining insights into the development of such diseases and for advancing with...

With the reopening of flights during the summer holiday season in Europe, many countries have started to see an increase in COVID-19 infections. A new IIASA-led study sheds light on how COVID-19 spreads regionally and between countries, as well as on how effective governmental measures to curb the spread of the pandemic have been to date.

A team of researchers from Japan has demonstrated a light-based reaction that yields high numbers of the base chemical component required to produce bioactive compounds used in common industry products. They published their results on June 11 in Organic Letters.

A novel mathematical modeling method has been developed to estimate operation models of biomolecular motors from single-molecule imaging data of motion with the Bayesian inference framework. The operation mechanism of a linear molecular motor "chitinase," which moves one-way on a chitin chain with degrading the chain passed by, was elucidated by mathematical modeling of experimental imaging data...

The tension in the outer membrane of cells plays an important role in a number of biological processes. A localized drop in tension, for example, makes it easier for the surface bend inward and form invaginations that will become free vesicles inside the cell. These are delimited by a membrane that contains all proteins originally present in the invaginations. A fundamental function of these...

New work led by Carnegie's Peng Ni and Anat Shahar uncovers new details about our Solar System's oldest planetary objects, which broke apart in long-ago collisions to form iron-rich meteorites. Their findings reveal that the distinct chemical signatures of these meteorites can be explained by the process of core crystallization in their parent bodies, deepening our understanding of the...

Prey can evade predators and also avoid attacks. However, some can escape from inside a predator after being swallowed. For example, some animals that can survive predators' digestive systems are excreted in feces and thereby escape, albeit in a passive manner. Now, for the first time, research has documented the quick, active escape of prey from the body of a predator after being eaten.

CNRS researchers at the Institut Curie have recently shown that cancer cells use a membrane protein that has been known for several decades to internalize iron. Published in Nature Chemistry, this work shows that the absorbed iron allows cancer cells to acquire metastatic properties.

A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience. The findings effectively throw cold water on the dominant "warm and wet ancient Mars" hypothesis, which postulates that rivers, rainfall and oceans once existed on the...

Generations of political support for sugar cultivation have helped India become the second-largest producer of sugar worldwide. Now, the country's commitment to renewable energy could create additional benefits, like conserving natural resources and providing better nutrition to the poor.
