Researchers have captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.

Researchers have been tracking a 26-foot endangered whale shark -- named 'Rio Lady' -- with a satellite transmitter for more than four years -- a record for whale sharks and one of the longest tracking endeavors for any species of shark.

Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.

World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists. Without this, work on tackling either crisis could inadvertently harm progress on the other.

A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.

A study extends the definition of a habitable zone for planets to include their star's magnetic field.

Biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. A study based on labor-intensive fieldwork and analysis in tropical mountain regions shows that a warmer and drier climate will lead to massive losses of plant species.

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the longstanding 'final parsec problem' in astronomy.

Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.

The first rumblings of the Sun's next 11-year solar cycle have been detected in sound waves inside our home star -- even though it is only halfway through its current one. This existing cycle is now at its peak, or 'solar maximum' -- which is when the Sun's magnetic field flips and its poles swap places -- until mid-2025.

Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.

Europe's next big space mission -- a telescope that will hunt for Earth-like rocky planets outside of our solar system -- is on course to launch at the end of 2026. PLATO, or PLAnetary Transits and Oscillations of stars, is being built to find nearby potentially habitable worlds around Sun-like stars that we can examine in detail.

So far, only about ten intermediate-mass black holes have been discovered in the entire universe. The newly identified black hole causes surrounding stars in a cluster to move in an unexpectedly orderly way.

Imagine a small fruit that tastes like a cross between a tomato and a pineapple, wrapped in its own natural paper lantern. That's the groundcherry (Physalis grisea) -- a little-known relative of tomatoes that's been quietly growing in gardens and small farms across North America for centuries. Now, this humble fruit is getting a 21st-century upgrade thanks to some cutting-edge genetic research.

A pioneering study has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. The study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.

In an era when the creation of artificial intelligence (AI) images is at the fingertips of the masses, the ability to detect fake pictures -- particularly deepfakes of people -- is becoming increasingly important. So what if you could tell just by looking into someone's eyes? That's the compelling finding of new research which suggests that AI-generated fakes can be spotted by analyzing human eyes in the same way that astronomers study pictures of galaxies.

The newly discovered planet TIC 241249530 b has the most highly elliptical, or eccentric, orbit of any known planet. It appears to be a juvenile planet that is in the midst of becoming a hot Jupiter, and its orbit is providing some answers to how such large, scorching planets evolve.

Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a permanent magnet and a coil. In contrast to electromagnets, they do not have to be permanently supplied with energy. In contrast to permanent magnets, their strength can be tuned: Whenever necessary, a strong electric pulse is sent through the coil, adapting the properties of the magnet.

Tantalizing evidence of potential dark matter objects has been detected with the help of the Universe's 'timekeepers'. These pulsars -- neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space -- were used to identify mysterious hidden masses. Pulsars earned their nickname because they send out electromagnetic radiation at very regular intervals, ranging from milliseconds to seconds, making them extremely accurate timekeepers.

Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. The discovery is surprising because it is not clear how a star that exploded winds up next to a star like our Sun.
