A new report raises serious questions about the benefits, risks and ethics of a new service -- which the authors call 'embryo selection based on polygenic scores,' or ESPS -- that allows in vitro fertilization patients to select embryos with the goal of choosing healthier and even smarter children.
The toxic blob of algae that turns western Lake Erie a ghastly shade of green each summer and threatens drinking water and fish should be on the smaller side again this year following another dry spring, scientists predicted Wednesday.
A new study maps the evolutionary history and interrelationships of protein domains, the subunits of protein molecules, over 3.8 billion years.
Even the mundane act of swallowing requires a well-coordinated dance of more than 30 muscles of the mouth. The loss of function of even one of these, due to disease or injury, can be extremely debilitating. For these people, nerve stimulation offers a ray of hope to regain some of their lost oral function.
Researchers propose a scheme to identify and weigh the quantum orbits in strong-field tunneling ionization.
Researchers have combined a new oxygen-sensing film with machine learning to create a wearable sensor capable of measuring tissue oxygenation through skin. The device could be used to monitor a person's oxygen levels on a continuous basis for applications in medicine and sports.
Virgin Galactic's Richard Branson won't say when he'll ride his rocket ship to space or whether he's looking to become the first billionaire to launch aboard his own rocket.
For the past few days, a heatwave has glowered over the Pacific Northwest, forcing temperatures in the region to a record-breaking 118ºF. Few people in the region—neither Americans nor Canadians—have air-conditioning. Stores sold out of new AC units in hours as a panicked public sought a reasonable solution to the emergency. Unfortunately, air-conditioning is part…
Ten estuaries on the West Coast of North America have been identified as priority locations for expanding the use of conservation aquaculture in a study led by the Native Olympia Oyster Collaborative and funded by the Science for Nature and People Partnership (SNAPP). SNAPP is a research collaboration supported by the National Center for Ecological Analysis & Synthesis (NCEAS) at UC Santa Barbara.
Proteins have been quietly taking over our lives since the COVID-19 pandemic began. We've been living at the whim of the virus's so-called "spike" protein, which has mutated dozens of times to create increasingly deadly variants. But the truth is, we have always been ruled by proteins. At the cellular level, they're responsible for pretty much everything.
Researchers studying the intersection of politics and psychology have long documented a link between threat sensitivity and social conservatism: People who are more socially conservative tend to react more strongly to threats. Conversely, those who are more socially liberal tend to be less sensitive to threats, viewing the world as a generally safe place and embracing change to explore new...
A team of scientists at the University of Illinois Chicago has developed a software tool that can help researchers more efficiently identify the regulators of genes. The system leverages a machine learning algorithm to predict which transcription factors are most likely to be active in individual cells.
Scientists—and gardeners—have long known that plants grow taller and flower sooner when they are shaded by close-growing neighbors. Now, for the first time, researchers at the Salk Institute have shown the detailed inner workings of this process.
Oil spills in the ocean have a devastating impact on the environment. More than 400,000 gallons of oil are spilled in oceans each year, affecting hundreds of square miles and killing more than 50,000 aquatic animals. In 2019 alone, five oil spills—three classified as major to medium—devastated ecosystems.
In 2009, famed music producer Phil Spector was found guilty of the murder of actress Lana Clarkson, who was found dead from a single gunshot to her mouth at close range in Spector's California mansion.
Campaigner for better treatments for people with brain cancerThe communications consultant Jessica Morris did much to give a voice to people who lacked one. In the years up to her death at the age of 57 from brain cancer, she made her illness the basis of a campaign to find treatments for others.In January 2016 she was hiking in a valley north of New York when she found herself trying to speak:...
Researchers have developed and successfully demonstrated a novel method for studying how cells repair damaged DNA in space.
Magnetic resonance imaging (MRI) is widely used in medicine to detect, diagnose and treat diseases such as cancer, while relying on experts' interpretation of images. Quantitative MRI, which obtains numerical measurements during the scans, can now potentially offer greater accuracy, repeatability and speed -- but rigorous quality control is needed for it to reach its full potential, according to a...
A study published in Science Advances reports on the unexpected observation of thermal waves in germanium, a semiconductor material, for the first time. This phenomenon may allow a significant improvement in the performance of our electronic devices in a near future. The study is led by researchers from the Institute of Materials Science of Barcelona (ICMAB, CSIC) in collaboration with researchers...
Language distinguishes us humans; we learn it through experience and social interactions. Especially in the first year of life, human vocalizations change dramatically, becoming more and more language-like. In our closest relatives, non-human primates, language development was previously thought to be largely predetermined and completed within the first few weeks after birth. In a behavioral study...
The Bronze Age in the eastern Mediterranean has long been considered by researchers to have been the 'first international age,' especially the period from 1600-1200 BC, when powerful empires from Anatolia, Mesopotamia, and Egypt set up large networks of subordinate client kingdoms in the Near East. These empires fought, traded, and corresponded with one another, and ancient texts from the period...
Researchers have developed and successfully demonstrated a novel method for studying how cells repair damaged DNA in space. Sarah Stahl-Rommel of Genes in Space and colleagues present the new technique in the open-access journal PLOS ONE on June 30, 2021.
A city's street names can provide a glimpse into its cultural value system and a way to quantify cultural indicators, according to a study published June 30, 2021 in the open-access journal PLOS ONE by Melanie Bancilhon from Washington University in Saint Louis, U.S., and colleagues.
A new study shows that a breathing exercise known as Inspiratory Muscle Strength Training can reduce blood pressure in weeks, with benefits on par with daily exercise or medication.
Researchers offers a new understanding of how gene activity directs plant growth, and how quickly plants respond to their environment -- with shifting light conditions triggering molecular changes in as little as five minutes. The findings provide insights into how to increase yield and safeguard world food production as climate change shrinks the planet's arable land.
Cancer cells can put the body's immune cells into sleep mode. Immunotherapy can reverse this, but it doesn't work for all patients and all cancer types. Researchers have now developed machine learning models that can predict if someone is likely to respond positively to immunotherapy. In clinical settings, this could pave the way for personalized immunotherapy approaches for patients, as well as...
New research shows that there may be more antimicrobial-resistant salmonella in our food animals than scientists previously thought.
Growing resistance to our go-to antibiotics is one of the biggest threats the world faces. As common bacteria like strep and salmonella become resistant to medications, what used to be easily treatable infections can now pose difficult medical challenges.

Academics believe they have identified a remarkable geological secret: A sunken continent hidden under Iceland and the surrounding ocean,which they have dubbed "Icelandia."
Richard Branson's Virgin Orbit delivered satellites from three countries into space Tuesday, its second rocket launch from a plane this year.
The Titanic is disappearing. The iconic ocean liner that was sunk by an iceberg is now slowly succumbing to metal-eating bacteria: holes pervade the wreckage, the crow's nest is already gone and the railing of the ship's iconic bow could collapse at any time.
An uncrewed Russian cargo ship blasted off Wednesday on a mission to deliver supplies to the International Space Station.
Pick up any product in just about any store and you're likely to find information that indicates the country of origin of the product. The U.S. Federal Trade Commission (FTC) requires this for any imported product, but not for products made in the United States. When you see the words "Made in U.S." on a product, it's purely for marketing purposes. So, does it work?
