Image: Hubble Telescope spies sparkling spray of stars in NGC 2660

This glittering group of stars, shining through the darkness like sparks left behind by a firework, is NGC 2660 in the constellation Vela, best viewed in the southern sky. NGC 2660 is an open cluster, a type of star cluster that can contain anywhere from tens to a few hundreds of stars loosely bound together by gravity.

Making 'transport' robots smarter

Imagine a team of humans and robots working together to process online orders -- real-life workers strategically positioned among their automated coworkers who are moving intelligently back and forth in a warehouse space, picking items for shipping to the customer. This could become a reality sooner than later, thanks to researchers who are working to speed up the online delivery process by...

Do voluntary corporate pledges help reduce plastic pollution?

A new analysis finds that while 72 percent of the top 300 companies on the Fortune 500 list have made voluntary pledges to reduce their plastic footprints, most are overwhelmingly focused on downstream waste-reduction strategies centered on recycling and packaging rather than on finding ways to reduce their use of virgin plastic, which is a main cause of the global plastic pollution problem.

NASA scientists create black hole jets with supercomputer

Leveraging the NASA Center for Climate Simulation (NCCS), NASA Goddard Space Flight Center scientists ran 100 simulations exploring jets—narrow beams of energetic particles—that emerge at nearly light speed from supermassive black holes. These behemoths sit at the centers of active, star-forming galaxies like our own Milky Way galaxy, and can weigh millions to billions of times the mass of the...

Researchers investigate neuron differentiation in fruit fly brains

The brains of all higher-order animals are filled with a diverse array of neuron types, with specific shapes and functions. Yet, when these brains form during embryonic development, there is initially only a small pool of cell types to work with. So how do neurons diversify over the embryo's development? Researchers know that neural stem cells called neuroblasts divide multiple times to...

Developing the low-energy ion spectrometer for the Chinese BeiDou-3 satellite

In our daily lives, we rely on weather forecasts to know whether it will rain tomorrow. The monitoring and prediction of space weather such as geomagnetic storms and substorms are also vital for the operation safety of satellites outside the atmosphere and the living conditions of astronauts in space. However, space weather is far more unpredictable than the weather on Earth, which depends on...

Most Asian countries are far behind biodiversity targets for protected areas, finds study of 40 countries

Protected areas are one of the most effective tools for safeguarding biodiversity, but new research published today has found that most Asian countries failed to achieve a global minimum target of protecting at least 17% of land by 2020. Under current trends, the outlook for achieving the Global Biodiversity Framework's 2030 target to protect at least 30% of land is bleak, with Asia set to miss...

Climate change will cause Pacific's low-oxygen zone to expand even more by 2100, study finds

For thousands of kilometers along the western coasts of the Americas, low-oxygen waters known as oxygen minimum zones stretch out into the Pacific Ocean. In part due to climate change, this oxygen-starved region is likely to get wider and deeper, expanding by millions of cubic kilometers by the end of the century, models in a new study predict. Larger oxygen minimum zones threaten marine...

New paper highlights the co-benefits of coordinating climate action and peacebuilding

Climate change can manifest in different ways: stronger tropical droughts, extreme droughts, warmer climates and highly unpredictable rainfall patterns. All these endanger the availability of food, which in turn could increase conflict over resources, which can turn violent in the absence of spaces for dialogs and negotiations to transform conflict by peaceful means. Violent conflict affects...
