KM3NeT

The Cubic Kilometre Neutrino Telescope, or KM3NeT, is a European research infrastructure located at the bottom of the Mediterranean Sea. It hosts the next-generation neutrino telescope with water Cherenkov detectors. When completed, KM3NeT will have a total instrumented volume of several cubic kilometres distributed over three locations in the Mediterranean: KM3NeT-Fr (offshore Toulon, France), KM3NeT-It (offshore Portopalo di Capo Passero, Sicily, Italy) and KM3NeT-Gr (offshore Pylos, Peloponnese, Greece). The KM3NeT project continues the work done for the neutrino telescope ANTARES operated offshore the coast of France between 2008 and 2022. Using KM3NeT, scientists search for neutrinos from distant astrophysical sources like supernova remnants, gamma-ray bursts, supernovae or colliding stars. The telescope is a powerful tool in the search for dark matter in the universe. Arrays of thousands of optical sensor modules detect the faint Cherenkov light in the deep sea from charged parti...

The northern giant hornet—once a major threat to honey bees and our ecosystems—is officially eradicated from the U.S.

  After five years of relentless effort, the northern giant hornet ( Vespa mandarinia ) has been eradicated from Washington State and the United States. The Washington State Department of Agriculture (WSDA) and USDA’s Animal and Plant Health Inspection Service (APHIS) announced this landmark achievement today. The announcement marked a significant victory in the ongoing fight against invasive species.  The northern giant hornet first captured national attention in late 2019 when it was detected near Blaine, Washington. Known for its ability to decimate a honey bee colony within hours, the hornet posed a serious threat to pollinators and all the life they support. However, this invasive predator is no longer a threat thanks to the collaborative efforts of APHIS, WSDA, researchers, and the public.  The northern giant hornet was first detected in North America in British Columbia, Canada in August 2019 and confirmed in Washington state in December 2019.  The Asian giant...

Crassulacean Acid Metabolism ( CAM )

As climate change triggers more frequent and longer-lasting droughts, water scarcity concerns are escalating. Only about 3% of the world's water is freshwater, and much of that is frozen in ice or otherwise unavailable for use. Agriculture is the biggest freshwater consumer worldwide, which emphasizes the need for hardier plants that can withstand drier conditions. Desert plants use a form of photosynthesis known as crassulacean acid metabolism, or CAM, to hold carbon dioxide in their cells overnight to be turned into sugars in the daylight hours. To survive extreme desert temperatures, CAM plants open their stomata, or leaf pores, to capture carbon dioxide only during the night and keep them closed during the heat of day to avoid water loss.

TRAPPIST-1: Largest Batch of Earth-sized Exoplanets

The most studied planetary system, aside from our own solar system, lies about 40 light-years away. We've looked at the seven rocky exoplanets orbiting the TRAPPIST-1 star with ground and space telescopes like Spitzer, Kepler, Hubble, and, now, the James Webb Space Telescope. In March 2023, the first science from the Webb telescope was released. An analysis of TRAPPIST-1b, the innermost planet, revealed its dayside temperature and found little evidence of an atmosphere. In a press release on February 22, 2017, NASA announced the discovery of the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds–all of them with the potential for water on their surface – is an exciting discovery in the search for life on other worlds. There is the possibility that future study of this unique planetary system could reveal conditions suitable for life. In February 2018, closer study of the seven planets suggested that some could...

Sentinel-1C: New radar satellite launched into space

  A new radar satellite supported by the UK was launched into space from French Guiana at 9:20pm GMT on Thursday 5 December. The Sentinel-1C satellite launched on a VEGA-C rocket and will orbit 700km above the Earth’s surface. Part of Europe’s Copernicus programme, it will use advanced radar technology to provide continuous imaging over land and sea, day and night, and even through cloud cover.  The UK’s Earth Observation industry is integral to the Sentinel 1 satellites, with the support of the UK Space Agency.  Airbus Defence and Space (Portsmouth) developed the electronics subsystem of the key Synthetic Aperture Radar (SAR) instrument aboard the satellite. Honeywell UK was responsible for the receiver of the Automated Identification System (AIS) payload, which will be key for maritime surveillance capabilities. Additionally, the battery for Sentinel-1C was supplied by Enersys ABSL (Abingdon).  Once it reaches its intended orbit, Sentinel-1C will synchronise with S...

Group of scientists urge halt research on Mirror Life Microbes

 Mirror life (also called mirror-image life) is a hypothetical form of life with mirror-reflected molecular building blocks. The possibility of mirror life was first discussed by Louis Pasteur. Although this alternative life form has not been discovered in nature, efforts to build a mirror-image version of biology's molecular machinery are already underway. Some scientists have proposed banning the creation of mirror life, including mirror bacteria, due to its potential to escape immune defenses and invade natural ecosystems. Homochirality Many of the essential molecules for life on Earth can exist in two mirror-image forms, referred to as "left-handed" and "right-handed" where handed refers to direction in which polarized light skews when beamed through a pure solution of the molecule, but living organisms do not use both. Proteins are exclusively composed of left-handed amino acids; RNA and DNA contain only right-handed sugars. This phenomenon is known as homo...

Social Determinants of Health (SDOH)

Social determinants of health (SDOH) are the nonmedical factors that influence health outcomes. They are the conditions in which people are born, grow, work, live, and age. These forces and systems include a wide set of forces and systems that shape daily life such as economic policies and systems, development agendas, social norms, social policies, and political systems. CDC has adopted this definition from the World Health Organization. Social determinants of health (SDOH) have a major impact on people’s health, well-being, and quality of life. Examples of SDOH include: Safe housing, transportation, and neighborhoods Racism, discrimination, and violence Education, job opportunities, and income Access to nutritious foods and physical activity opportunities Polluted air and water Language and literacy skills SDOH also contribute to wide health disparities and inequities. For example, people who don't have access to grocery stores with healthy foods are less likely to have good nutr...
