"Today was great !" my 7-year-old exclaimed recently when I came home from work. By cosmic standards, her day wasn't that special. She went to the playground, where she finally mastered the monkey bars. She visited the history museum—or at least its gift shop. She got "really big" nachos. She went to the kids' art studio. Two years ago, visiting a museum and a nacho joint was so common, it wouldn
Cracking the Corona A NASA probe has done the seemingly impossible and "touched" the Sun. NASA has officially acknowledged that its Parker Solar Probe dipped below the upper part of the Sun's atmosphere known as the corona and "touched the Sun," in the agency's phrasing . It actually made its momentous flight in April , but it took months for the data to relay back to Earth and for researchers to
Einstein was no stranger to mathematical challenges. He struggled to define energy in a way that acknowledged both the law of energy conservation and covariance, which is general relativity's fundamental feature where physical laws are the same for all observers.
Terror Launch NASA is about to blast a massive space telescope into space that has cost the agency approximately $10 billion and more than 20 years to build — meaning that astronomers are absolutely horrified by the possibility that something could go wrong during the launch later this month, The New York Times reports . "I will almost certainly watch the launch and be terrified the entire time,"
Researchers looking into the interplay between hormones and ethics discovered something that will shock nobody who dates men: that those with high testosterone levels end up being bigger jerks. As PsyPost reports , a recent study out of HEC Montréal complicates previous research associating high T-levels with business success by linking the hormone with unethical behavior in sexual scenarios — or
Suspicious Death The local police department in Fremont, California has reported a "suspicious death " that occurred on December 13 in the parking lot of Tesla's factory in the area. According to a statement received by CNBC , a Tesla worker "had just finished a shift at the Tesla manufacturing factory before being shot in the parking lot as he left." It's even more grim news involving Tesla's op

Cow Spotting Scientists may have caught a black hole — or possibly a neutron star — in the act of being born. In 2018, astronomers spotted a mysterious signal coming from some 200 million light years away. At first, they thought it was a supernova, but it was far brighter and quicker than any previous explosion. The event, later given the suitable nickname "the Cow," has puzzled scientists for ye

My breakthrough infection started with a scratchy throat just a few days before Thanksgiving. Because I'm vaccinated, and had just tested negative for COVID-19 two days earlier, I initially brushed off the symptoms as merely a cold. Just to be sure, I got checked again a few days later. Positive. The result felt like a betrayal after 18 months of reporting on the pandemic. And as I walked home fr

When we encounter an unfamiliar face, we tend to make snap judgments. Does the person look smart, attractive, or young? Are they trustworthy or corrupt? Neuroscientists and psychologists study how our brains form these facial biases, and how the judgments ultimately influence the way people behave.
Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than those used today. The new sensor architecture could enable digital cameras that can image faster or in conditions with less light.
Materials Scientists at Duke University have developed a lightweight material that traps thermal energy when dry, but opens a series of tiny vents to let heat escape when a person starts sweating. The vents close again to retain heat once they are dry.
When alien plants integrate into an existing ecosystem and successfully spread, in rare cases, it can contribute to the increased uniqueness of the regional flora. However, much more often, this process—known as naturalization—leads to a homogenization of regional floras and thus to a net loss of global floristic uniqueness. Super-invaders, which are highly effective at colonizing new territory an
New research reveals a previously underappreciated way old-growth forests have been recycling and storing carbon: Treetop soils. Branches in forest canopies can hold caches of soil that may store substantially more carbon than soils on the ground beneath them, and scientists are just beginning to understand how much carbon canopy soils—which exist on every continent except Antarctica—could store.
Globally, plants are reaping the benefits of elevated CO2 levels in the atmosphere by increasing photosynthesis rates, a phenomenon known as the CO2 fertilization effect. However, those benefits might be offset by drier and warmer climates caused by global warming and extreme climate events. Using data collected from urban environments, researchers at Illinois have been able to study dueling effec
While much is known about extreme weather events on land, there has been little research into those that occur in the ocean. A study led by ETH Zurich uses models to show for the first time that marine heatwaves, and extremes with high acidity or low oxygen can also occur conjointly—with difficult to foresee consequences for marine life.
Hunter-gathers caused ecosystems to change 125,000 years ago. These are the findings of an interdisciplinary study by archeologists from Leiden University in collaboration with other researchers. Neanderthals used fire to keep the landscape open and thus had a big impact on their local environment. The study will be published in the journal Science Advances on 15 December.

Epileptic encephalopathy (EE) is characterized by seizures that respond poorly to antiseizure drugs, psychomotor delay, and cognitive and behavioral impairments. One of the frequently mutated genes in EE is KCNQ2, which encodes the Kv7.2 subunit of voltage-gated Kv7 potassium channels. Kv7 channels composed of Kv7.2 and Kv7.3 are enriched at…
The presence of a single cluster of nonoptimal codons was found to decrease a transcript's half-life through the interaction of the ribosome-associated quality control machinery with stalled ribosomes in Saccharomyces cerevisiae. The impact of multiple nonoptimal codon clusters on a transcript's half-life, however, is unknown. Using a kinetic model, we…
Cancer survivors rank sensorimotor disability among the most distressing, long-term consequences of chemotherapy. Disorders in gait, balance, and skilled movements are commonly assigned to chemotoxic damage of peripheral sensory neurons without consideration of the deterministic role played by the neural circuits that translate sensory information into movement. This oversight precludes…
Autoantigen discovery is a critical challenge for the understanding and diagnosis of autoimmune diseases. While autoantibody markers in current clinical use have been identified through studies focused on individual disorders, we postulated that a reverse approach starting with a putative autoantigen to explore multiple disorders might hold promise.

Nick McKeown, senior vice president and general manager of the network and edge group at Intel Corporation says this technical leap is what will make futur
The purpose of a standard, from a marketing perspective, is to tell customers what a device can or cannot do in just a few words. It's much faster to read "This device supports DirectX 12" than it would be to scan a table of DirectX 12 requirements to make certain a GPU was compatible with the API. But standards only work if they are designed properly. Based on what we now know about HDMI 2.1, it

The expansion of the genetic code by incorporating universal amino acids (UAAs) with diverse functional groups has enabled the synthesis of proteins with enhanced or novel functions, and the construction of UAA-dependent synthetic auxotrophs.
Four CubeSats—CubIXSS, SunCET, DYNAGLO, and WindCube—have been selected by NASA's Heliophysics Flight Opportunities in Research and Technology program in cooperation with NASA's Space Weather Science Application. Together, they will comprise a first-generation testbed for space weather innovation through small satellites.
Researchers have developed a catalyst that converts methane into chemicals used to make plastics and other materials. Methane produces more warming than other greenhouse gases and is the subject of newly announced US emission restrictions. It's hard to break down and keep out of the atmosphere. "Remarkably, these novel catalysts run for 72 hours of continuous operation without any signs of deacti
Researchers have identified novel changes in gene network interactions associated with cancer that may lead to new treatment targets for chemotherapy. Their work shows that more than 90% of changes in gene network interactions in nine types of cancer studied are not detectable by current tests focused on changes in gene expression.
Researchers have demonstrated a proof-of-concept modification to enable standard MRI systems to detect frequencies associated with the presence of sodium-23 ions. This low-cost and convenient approach requires the installation of a radio-frequency repeater inside the magnetic bore of an MRI machine. The wide applicability of this method for sodium and other nuclei may allow advanced medical imagin
Abundant, safe, and environmentally friendly, tin sulfide is predicted to be used in next generation solar cell panels. Now, a research group has used impurity doping to fabricate n-type conductive tin sulfide thin films, paving the way for their use in solar cells.
People who suffer from both insomnia and obstructive sleep apnea are more likely to suffer from heart problems and are almost 50% more likely to die than those without either condition, say researchers, who advise people being tested for one of the disorders be tested for the other.
Biophysicists have found ways to make and manipulate capsule-like DNA structures that could be used in the development of artificial molecular systems. Such systems could function, for example, inside the human body.
Machine learning—computer algorithms that improve themselves without direct programming from humans—can improve lightning forecasts, a new study shows. Lightning is one of the most destructive forces of nature, as in 2020 when it sparked the massive California Lightning Complex fires, but it remains hard to predict. Better lightning forecasts could help to prepare for potential wildfires , improv
Hey guys, I'm currently on my first year of studying Cognitive Science&Philosophy in a university in Israel. I want to pursue a degree in this field, but I understood that I want to study abroad. As the English speaking countries are extremely expensive, I'm searching for English taught programs in Europe. (up to 4k euros a year, let's say). The difficulty I encounter is that none of the programs
Ion channels in the nervous system are among the most important targets for insecticides. Understanding the structure of the channels is key for the identification of novel species-specific binding sites of agrochemicals. Researchers have revealed the structure and function of a potassium ion channel in fruit flies. Their newly obtained insights reveal the differences between human and insect chan
Citrus greening, also known as huanglongbing (HLB), has emerged as the most significant disease in citrus (Citrus sp.) agriculture. The disease is associated with the Candidatus Liberibacter species of bacteria. The most prevalent and virulent species in this group is Candidatus Liberibacter asiaticus (CLas). It is primarily vectored by the asian citrus psyllid ACP (Diaphorina citri).
Whether you're prone to dropping or scratching up your devices (hey, no judgement here) or you're incredibly meticulous when it comes to taking care of them, accidents happen. When it comes to protecting and keeping your phone or tablet clean, it's best to put your best foot forward to promote longevity. A good place to start is one of the best screen protectors. Designed for a multitude of devic
More than a year into the pandemic, Washington nonprofits have shown resiliency in serving their communities and staying afloat, a study from the Evans School of Public Policy & Governance at the University of Washington shows.
With numerous recent studies demonstrating that antibiotics work as well as surgery for most uncomplicated appendicitis cases, the non-surgical approach can now be considered a routine option, according to a review article.
Patients with colorectal cancer were among the first to receive targeted therapies. These drugs aim to block the cancer-causing proteins that trigger out-of-control cell growth while sparing healthy tissues. But some patients are not eligible for these treatments because they have cancer-promoting mutations that are believed to cause resistance to these drugs. Now, physician-scientists have used c
Whether it's warm outside or cold, people generally eat about the same amount. But a fish's appetite can vary enormously with the temperature. As coldblooded animals, their metabolism is governed by external conditions: It's slow going for a cold fish, but high temperatures kick them into high gear.
Researchers have identified brain signals associated with obsessive compulsive disorder symptoms, paving the way for adaptive treatment. The researchers recorded electrical signals in the human brain associated with ebbs and flows in OCD symptoms over an extended period in participants' homes as they went about daily living. The research could be an important step in making an emerging therapy ca
