Hundreds of US flights are canceled for the 4th straight day. Here’s the latest on the global tech outage

Posted by in category: transportation

Hundreds of US flights were canceled Monday, as carriers, particularly Delta Air Lines, work to recover four days after a global tech outage caused massive delays and left travelers stranded at airports around the nation.

Delta is facing mounting pressure to get passengers back in the air, as it continues to rack up the majority of canceled US flights. US Transportation Secretary Pete Buttigieg has expressed frustration with the pace of Delta’s recovery and its CEO has apologized to affected travelers.

More than 900 flights into, within or out of the United States were canceled by midday Monday, and 3,100 flights were delayed, according to flight tracking site FlightAware. Delta passengers have been slammed by more than 4,500 cancellations since Friday, including 748 on Monday, by far the most of any airline.

34-Million-Year-Old Snake Discovered in Wyoming Changes Our Understanding of Evolution

Posted by in category: evolution

A newly discovered fossil snake species in Wyoming is transforming our understanding of snake evolution. Unearthed from a burrow where four well-preserved specimens were found intertwined, this species, named Hibernophis breithaupti, lived in North America 34 million years ago. This discovery provides valuable insights into the origins and diversification of boas and pythons.

Hibernophis breithaupti has unique anatomical features, in part because the specimens are articulated—meaning they were found all in one piece with the bones still arranged in the proper order—which is unusual for fossil snakes. Researchers believe it may be an early member of Booidea, a group that includes modern boas and pythons. Modern boas are widespread in the Americas, but their early evolution is not well understood. These new and very complete fossils add important new information, in particular, on the evolution of small, burrowing boas known as rubber boas.

First of its kind Detection made in Striking New Webb Image

Posted by in category: space

For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area (seen at the upper left) of this young, nearby star-forming region.

Astronomers found an intriguing group of protostellar outflows, formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds. Typically these objects have varied orientations within one region. Here, however, they are slanted in the same direction, to the same degree, like sleet pouring down during a storm.

The discovery of these aligned objects, made possible due to Webb’s exquisite spatial resolution and sensitivity in near-infrared wavelengths, is providing information into the fundamentals of how stars are born.

3D-Printed Chip Sensor Detects Foodborne Pathogens for Safer Products

Posted by in categories: 3D printing, computing, food

Chip design can rapidly and efficiently test for multiple pathogens simultaneously, potentially reducing foodborne illness. Researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types of pathogens simultaneously and is created using 3D printing, making it easy to fabricate in large amounts and modify to target specific pathogens. The researchers hope their technique can improve screening processes and keep contaminated food out of the hands of consumers.

Every so often, a food product is recalled because of some sort of contamination. For consumers of such products, a recall can trigger doubt in the safety and reliability of what they eat and drink. In many cases, a recall will come too late to keep some people from getting ill.

In spite of the food industry’s efforts to fight pathogens, products are still contaminated and people still get sick. Much of the problem stems from the tools available to screen for harmful pathogens, which are often not effective enough at protecting the public.

New Study confirms Forever Chemicals are Absorbed through Human Skin

Posted by in categories: chemistry, government

A study of 17 commonly used synthetic ‘forever chemicals’ has shown that these toxic substances can readily be absorbed through human skin.

New research, published today in Environment International proves for the first time that a wide range of PFAS (perfluoroalkyl substances) — chemicals which do not break down in nature – can permeate the skin barrier and reach the body’s bloodstream.

PFAS are used widely in industries and consumer products from school uniforms to personal care products because of their water and stain repellent properties. While some substances have been banned by government regulation, others are still widely used and their toxic effects have not yet been fully investigated.

Study unveils complexity of zoonotic transmission chains

Posted by in categories: biotech/medical, food

Researchers from the Complexity Science Hub and the University of Veterinary Medicine Vienna have dissected the complex interactions involved in zoonoses, which annually affect over two billion people worldwide. They introduce the concept of a “zoonotic web,” a detailed network representation of the relationships between zoonotic agents, their hosts, vectors, food sources, and the environment.

Gold co-catalyst improves photocatalytic degradation of micropollutants, finds study

Posted by in categories: chemistry, nanotechnology

To remove micropollutants such as pesticides and trace chemicals from the environment, you need something equally small and cunning. One potential method is photocatalysis, which uses semiconducting nanomaterials powered by sunlight to adsorb toxic chemicals on the materials’ surface and degrade them.
