It all began with a molecular cloud.
A study in GeoScienceWorld.
It all began with a cloud. That cloud was mostly hydrogen, water’s main component, with a touch of helium, oxygen, and carbon.
The oxygen in the cloud then came into contact with a dust grain. It froze and adhered to the surface.
The European Space Agency recently announced a new mission of its science program: a small telescope orbiting the Earth dubbed Arrakhis.

Instead, this nimble satellite will punch hugely above its weight and try to track down one of the most elusive and mysterious substances in the universe: dark matter. This is the term given to the hypothetical invisible matter that is thought to be more abundant than normal matter and has a similar gravitational effect on its surroundings.
The three major lessons on energy security.
On October 19, European Commission president Ursula von der Leyen announced that the EU had replaced two-thirds of its Russian gas imports since February by switching to other suppliers. Such a turnaround seemed unattainable last spring when the invasion of Ukraine turned Moscow from an EU business partner into a military threat.
Despite the EU’s reduction of its energy dependence on Russia, there is work to be done in the long term. To achieve autonomy from Russian energy, the Union could learn from the experience of one of its members, Lithuania – a country which, since declaring its independence from the USSR in 1990, has been able to adapt to a complex geopolitical context to ensure its energy security.
The Lithuanian case has three major lessons.
This course equips students to see space exploration not only as rocket science but also as a topic for social science.
Uncommon Courses is an occasional series from The Conversation U.S. highlighting unconventional approaches to teaching.

The innovation was inspired by the measles virus.
In a world-first, researchers at Tel Aviv University have conceived of a way to control the encapsulation and release of drug molecules by exposure to UV light, according to a press release by the institution published on Monday.
The scientists now hope that this new efficient encapsulation will allow for the high loading capacity of molecules leading to further development of delivery systems for the controlled release of biomolecules and drugs in the body by external stimuli using light.
More than 15,000 cameras have been placed throughout the eight stadiums and along roads and transportation infrastructure in Doha.
As Lionel Messi faces Kylian Mbappé in Argentina vs France World Cup final match in Qatar, which billions prepare to watch, cybersecurity experts warn that the event may be a hotspot for cyber threats.
“With major sporting events becoming increasingly digitized, the attack surface for threat actors has also increased,” a recent ZeroFox report on World Cup threats stated.

With the arrival of AI-generated art and the proliferation of tools like Midjourney, Stable Diffusion and DALL-E, questions have been rife in circles across the creative industry.
Is this a temporary trend? Or a would-be essential tool in creative communication?
Seizures come suddenly, triggered by stress, fever, flashing lights, or even just feeling tired. Some cause the body to jerk and shake while others can produce strange sensations, make one lose a sense of awareness, or faint. They can happen when the person is awake or asleep. When they pass, after a few seconds or minutes, they leave people tired, confused, and disoriented.
The brain usually maintains a certain level of inhibition that keeps neurons from firing uncontrollably. But during a seizure, one part of the brain starts firing too frantically and can’t stop, resulting in a spike of electrical activity and a seizure.
