The Antarctic water becomes salty and promotes the collapse of sea ice. Scientists don’t know why.Antarctic sea ice has been declining since 2015, contrary to the model’s forecasts that it will reach a record 0.6 million square miles (1.55 million square kilometers) above the expected average range for 2023, in opposition to the model’s forecast.This decline — the biggest environmental change seen anywhere on the planet in recent decades — will have ripple effects on the global climate. You might like it Now, scientists are linking decline to an unexpected, yet unexplained rise in the salty taste of the water…
Up to three people in every 1,000 newborns have hearing loss in one or both ears. Cochlear implants provide significant hope for these children, but invasion surgery is required. These implants are also unable to fully replicate the nuances of natural hearing.However, a recent study by my colleagues and I have shown that a form of gene therapy can successfully restore hearing in young children and young adults born with congenital hearing loss.Our study focused specifically on young children and young adults born with OTOF-related hearing loss. This condition is caused by a mutation in the OTOF gene, which produces…
The major Atlantic currents, which appear to be slowing down due to climate change, may be more resilient to global warming than scientists previously thought. New research shows thanks to a secret backup system.The Atlantic Meridian Surrounding Circulation (AMOC) is a network of currents that loop around the Atlantic Ocean like a giant conveyor belt. The cold, salty waters sink near Greenland and move south along the seabed. Eventually these waters rise back to the surface near the Antarctic, returning north, bringing the Balmier waters to the northern hemisphere. This system is particularly important for warming Europe.In recent years, experts…
NASA has released a photo of the nearest sun, taken by Parker solar probes just 3.8 million miles (6.1 million kilometers) from the star’s surface. The new image reveals important features of solar winds that help scientists understand the origins of this mysterious spatial meteorological phenomenon and its impact on life on Earth.Solar wind is a constant flow of charged particles (mainly protons and electrons) emitted by the outer atmosphere of the sun, known as corona. This rapid of material runs through the solar system over a million miles from the Sun, combining it with magnetic fields and materials abandoned…
The child’s skull contains a mixture of features that appear to be consistent with both modern Homo sapiens and Neanderthals. (Image credit: Israel Herskovitz/Tel Aviv University)One of the earliest known human burials, one of the burials of young children, may have been a cross between modern humans and Neanderthals, new research suggests.Researchers analyzed a skull found at a burial site 140,000 years ago and concluded that the child it belongs to has both modern human (Homo sapiens) and Neanderthal traits. However, the exact ancestor of a child is still uncertain.The skull was part of a cache of mysterious human remains…
Maharashtra, India — After working an hour in a sugar cane field, Shakuntala Admane began to feel the lighthead, but she stuck for another four hours. She then collapsed as the temperature spiked above 104 degrees Fahrenheit (40 degrees Celsius).Medical testing confirmed that a 60-year-old agricultural worker had hyponatremia. This is a condition in which sodium levels in the blood are too low. If left untreated, hyponatremia can lead to brain swelling, seizures, coma, muscle collapse, and even death.Admane – from Yadrav, a village in Maharashtra, West India – was not alone. With temperatures rising above 95 F (35 C)…
July 11, 2025Ravi LakshmananUS Fortinet has released fixes for critical security flaws affecting FortiWeb. This allows an unauthorized attacker to execute arbitrary database commands on the sensitive instance. Tracked as CVE-2025-25257, the vulnerability has a CVSS score of 9.6 out of 10.0. Inappropriate neutralization of special elements used in SQL command (“SQL Injection”) vulnerabilities [CWE-89] FortiWeb could allow unauthorized attackers to execute malformed SQL code or commands via HTTP or HTTPS requests created,” Fortinet said in an advisory released this week. The drawbacks affect the next version – Fortiweb 7.6.0 to 7.6.3 (7.6.4 or later) FortiWeb 7.4.0 (upgraded to 7.4.8…
Apolink, a Y-combinator-assisted space technology startup founded by a 19-year-old Indian entrepreneur, raised $4.3 million in a “overregistered” seed round with a $45 million money post money rating, creating a real-time network of low-earth orbit (LEO) satellites. Startups are tackling the persistent issues of space communication. Satellites frequently travel offline in parts of orbit due to dead zones. Relay satellites and global ground station networks can help reduce this downtime, but only provide partial solutions. That gap has become important as the space industry evolves. For years, NASA relied on its tracking and data relay satellite (TDRS) system to maintain…
When Openai met the ChatGpt moment in 2022, Joe Scheidler, co-founder and CEO of Helios, was working on a different kind of challenge. It helps build the White House’s newly licensed cybersecurity office and navigates the complexities of public-private coordination regarding cyber policies. His current co-founder, Joseph Falsaf, is also at the State Department, working on the Yemen Hooty peace negotiations. The two began trading notes on how large-scale language models translate public policy at a daily level. At the level operated by the White House, important decisions are often made using patchwork of tools, spreadsheets, and institutional memory. The…
