The United States has had a federal equal pay law on the books for close to 60 years—and yet some projections estimate it'll be another 30 years before women and men finally earn the same. On Boston's Equal Pay Day on April 20, a new tool has been launched that aims to help businesses comply with the law and close their earnings gaps.

The United States announced a commitment to stop testing anti-satellite missiles that generate dangerous debris in space, a measure described Tuesday as "an important step" by the head of NASA.

The unprecedented spikes in demand for personal protective equipment (PPE) and respirators initially made the corona crisis a procurement crisis as well. The MaSSC research (Material Supply Strategies in a Crisis) studied the procurement strategies for these scarce resources in the Netherlands and 33 other countries worldwide. Which structures and strategies turned out to be successful or unsuccessful, and especially, what can healthcare organizations and countries do to purchase more effectively and be more in control in a next crisis?

For most of us, when we make major career choices, we tend to lean into what we're good at. According to new findings from the University of California San Diego's Rady School of Management, such skills may develop early in childhood and there can be significant differences depending on gender.

The first global initiative aimed at ending street homelessness has revealed key ingredients for success along with common systemic barriers, new research from Heriot-Watt University has found.

Roughly 6% of the UK population provide informal unpaid care, and 60% of people in the UK will be carers at some point in their lives. This includes a number of people who are carers while studying at university.

This prototype NIST sensor may help solve some mysteries of the universe by looking beyond the Standard Model.

DNA is the blueprint of life. All the information that an organism needs to survive, reproduce, adapt to environments or survive a disease is in its DNA.

Radu Custelcean, an organic chemist at the Department of Energy's Oak Ridge National Laboratory, is working with colleagues to develop an energy-efficient and sustainable method for scrubbing carbon dioxide directly from the air so that it can be stored underground or converted into useful products such as ethanol, which can be used to make products ranging from fuel to hand sanitizer. The technology won an R&D 100 Award and is currently being licensed to private companies including Holocene and Reactwell.

The CMS collaboration at the Large Hadron Collider (LHC) has performed the most accurate ever measurement of the mass of the top quark—the heaviest known elementary particle. The latest CMS result estimates the value of the top-quark mass with an accuracy of about 0.22%. The substantial gain in accuracy comes from new analysis methods and improved procedures to consistently and simultaneously treat different uncertainties in the measurement.

The term "superspreader event" has become well known since the emergence of the COVID-19 pandemic, although such events are not without precedence throughout history. Such an event involves a large gathering of people wherein several individuals who are carriers of an infectious disease spread the disease to those with whom they come into contact at the event: Those newly infected individuals take away with them the potential to spread the disease to family, friends, work colleagues and many others.

Asking customers to leave specific tip amounts before food is delivered or provided prompts larger gratuities but also leads to lower satisfaction—especially if the payment page design is crowded, I found in new research I co-authored.

The deep-sea crown jelly Atolla is one of the most common residents of the ocean's midnight zone. Its bell has a signature scarlet color and bears one tentacle much longer than the rest. So 15 years ago, when MBARI researchers spotted a jelly that looked like Atolla, but lacked the telltale trailing tentacle, their curiosity was piqued.

NOAA Fisheries is launching a new tool to better track the location and movement of marine fish in U.S. waters. The Distribution Mapping and Analysis Portal reveals that the ranges of many marine species are shifting, expanding and contracting in response to changing ocean conditions. The interactive website will improve data sharing and collaboration, facilitate decision-making about fishery management and science and increase overall knowledge of species distribution for stock assessments.

As they become more exposed to the grim realities of climate change, today's teens and people in their 20s—an entire generation—are experiencing increased anxiety, grief, fear or guilt about the planet's future as well as their own.

Researchers at Dartmouth College have built the world's first superfluid circuit that uses pairs of ultracold electron-like atoms, according to a study published in Physical Review Letters.

An international team of scientists led by Trinity College Dublin tagged and released a record-breaking 2.8 m porbeagle shark, Lamna nasus, off the coast of Donegal last week.

Over the last three years the Roleystone community and wildlife rehabilitation centers have become concerned over increasing numbers of the small marsupial, otherwise known as the southwestern brown bandicoot, seen with severe skin disease in local reserves and backyards.

Jaguars are the only species of big cat found on the American continent. They range as far south as Argentina, and once roamed as far north as the Grand Canyon in the U.S. Today the northernmost breeding population is in the northwest Mexican state of Sonora, just south of the border with Arizona.

Indigenous lands in the Brazilian Amazon are under constant pressure, and deforestation of these areas has accelerated in recent years. Some of them, such as Apyterewa Indigenous Territory in Pará state, are particularly affected, endangering Brazil's ability to meet the targets to which it is committed internationally in terms of combating deforestation and mitigating the impact of climate change. To protect the areas of the Amazon that are still intact, effective action must be taken to enforce the nation's environmental laws.

After collecting eight rock-core samples from its first science campaign and completing a record-breaking, 31-Martian-day (or sol) dash across about 3 miles (5 kilometers) of Mars, NASA's Perseverance rover arrived at the doorstep of Jezero Crater's ancient river delta April 13. Dubbed "Three Forks" by the Perseverance team (a reference to the spot where three route options to the delta merge), the location serves as the staging area for the rover's second science expedition, the "Delta Front Campaign."

New research led by Western Sydney University has found that male lyrebirds 'compose' long complex songs created out of mimicked sounds 'sampled' from their environment, and share these songs with their neighbors.

Utopia literally means an imaginary ideal place that in principle can never be realized. However, in practical regional development, utopia-likeness is needed, because it promotes, involves and inspires social reforms, says Mikko Karhu, Licentiate of Administrative Sciences, who is defending his doctoral dissertation at the University of Vaasa on 22 April.

The best word to describe supply chain performance in the past two years is turbulent. Supply chain operators and customers alike continue to dream of days past when goods were available, and bottlenecking was at a minimum. As there is seemingly no end in sight to the current supply chain woes, LSU Department of Marketing Assistant Professor Kris Lindsey Hall, Ph.D. student Ripinka Koli Patil, and co-authors explored the many factors that impact a firm's logistics performance. Their recent article... Читать дальше...

The red smoke of a flare on a roadway warns motorists to be cautious, but the anthraquinone dyes currently used to produce this smoke are thought to be harmful to human health. Now, researchers reporting in ACS Sustainable Chemistry & Engineering have identified a less toxic, "greener" alternative—an organic dye called pigment red 254 (PR254). It also forms a red-colored smoke cloud more effectively than current dyes, the researchers say.
