Chemists created an enzyme with boronic acid at its reactive center. This approach can produce more selective reactions with boron, and allows the use of directed evolution to improve its catalytic power.
SpaceX keeps lining them up and knocking them out with an afternoon launch from Kennedy Space Center on Wednesday.
Dogs brought into the United States from abroad must be compliant with new rules to help fight rabies in this country, according to updated guidance from the Centers for Disease Control and Prevention issued Wednesday.
An experimental spy satellite that was deemed "lost" after eluding detection for decades has finally been found. "The S73-7 satellite has been rediscovered after being untracked for 25 years," astrophysicist Jonathan McDowell said in an April 29 post on X, formerly Twitter. He
Summer can be an extra challenging time for Texas's 189 major water supply reservoirs. With temperatures consistently reaching 100 degrees or higher, reservoir evaporation rates see high increases.
A research team at Los Alamos National Laboratory is using computer models to simulate how climate change could expand the geographical range in which mosquitoes live, which may cause an increase in mosquito-borne illness. The study was recently published in the Journal of
Food-borne diseases like typhoid, caused by Salmonella Typhimurium, are a severe threat to public health, especially in India. The indiscriminate use of antibiotics has allowed this bacterium to become resistant, posing a major hurdle in treating infections.
After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC 4151.
Neuropathy, the nerve damage that causes pain and numbness in the feet and hands and can eventually lead to falls, infection and even amputation, is very common and underdiagnosed, according to a new study.
Domestic soybeans serve as an important source of healthy edible plant oil and high-quality plant protein in our food culture. In addition to the well-known components of oil (approximately 20%), protein (approximately 40%), and carbohydrates (approximately 30%), soybean seeds
One of the most important decisions an entrepreneur can make when launching a business is choosing the right co-founder. Should compatible personalities guide the choice? Or should the priority be someone who brings resources to the startup? How do entrepreneurs make this
The share of consumers who indicated they are either "rather happy" or "very happy" with their diets rose from 81% in January 2024 to 87% last month, according to the April 2024 Consumer Food Insights Report. This surprising finding follows extensive media attention devoted to
Red blood cells (RBCs) transport oxygen throughout the body and are able to pass through a complex of narrow capillaries due to their ability to deform. "The deformability of RBCs is an important indicator of their health and functionality, and changes in this property can
The Australian brook lamprey (Mordacia praecox) is part of a group of primitive jawless fish. It's up to 15 cm long, with rows of sharp teeth. Surprisingly, it doesn't use these teeth to suck blood like most lamprey species—it's non-parasitic.
Retrosynthesis aims to predict a set of reactants for producing given molecules, which plays a significant part in the biochemistry field, such as molecular pathway design and drug discovery. Most existing methods only benefit from one kind of information rather than further
More compassion = a better relationship. This is an obvious rule of thumb for couples. But it doesn't apply to everyone, as a study shows. Some people prefer to do without it.
Security seems to most people a basic necessity of life, a prerequisite for a good life. But if you think about it a little longer and more deeply, as political philosopher Josette Daemen has done, you realize that security sometimes comes at the expense of other important
The income of many people around the world has considerably increased due to the economic globalization of the last 50 years. However, these income gains are unevenly distributed. A study by Dr. Valentin Lang, junior professor of political economy at the University of Mannheim,
The sun is increasing its intensity on schedule, continuing its approach to solar maximum. In just over a 24-hour period on May 5 and May 6, 2024, the sun released three X-class solar flares measuring at X1.3, X1.2, and X4.5. Solar flares can impact radio communications and
The Gum Nebula is an emission nebula almost 1400 light-years away. It's home to an object known as "God's Hand" among the faithful. The rest of us call it CG 4.
Latin America and the Caribbean had their warmest year on record in 2023 as a "double-whammy" of El Niño and climate change caused major weather calamities, the World Meteorological Organization said Wednesday.
Capturing carbon dioxide (CO2) from the atmosphere to store underground "sounds too good to be true", a climate expert told AFP, yet the technology to increase its capacity tenfold is already being tested.
The junction composed of traditional metals and 2D semiconductors is a key component of semiconductor devices.
Multicomponent ultra-high temperature ceramic (UHTC) has attracted much attention in research due to its superior high-temperature mechanical properties, lower thermal conductivity and enhanced oxidation resistance.
In recent years, the exceptional structure and fascinating electrical and optical properties of two-dimensional (2D) layered crystals have attracted widespread attention. Examples of such crystals include graphene, black phosphorus (BP), and transition metal dichalcogenides
