Surprising similarities in stone tools of early humans and monkeys
2023-03-10
The research is based on new analyses of stone tools used by long-tailed macaques in the Phang Nga National Park in Thailand. These monkeys use stone tools to crack open hard-shelled nuts. In that process, the monkeys often break their hammerstones and anvils. The resulting assemblage of broken stones is substantial and widespread across the landscape. Moreover, many of these artefacts bear all of the same characteristics that are commonly used to identify intentionally made stone tools in some of the earliest archaeological sites in East Africa.
“The ability to intentionally make ...

High-speed super-resolution microscopy via temporal compression
2023-03-10
As an indispensable tool for observing the microcosmos, optical microscopy has boosted the development of various fields, including biology, medicine, physics, and materials. However, optical diffraction imposes a spatial resolution restriction on optical microscopy, which hampers exploration of finer structures.
To overcome the resolution limitation, various super-resolution microscopy techniques based on diverse principles have been proposed. Yet these techniques commonly acquire super-resolution at the expense of reduced imaging speed, so achieving high-speed super-resolution ...
Research Brief: Jewel beetles evolve to see new colors by duplicating their genes
2023-03-10
Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. Possessing large, well-developed eyes, jewel beetles use vision and color for a range of different behaviors, including finding mates and host plants.
Color vision in insects differs from our own. Special genes allow many insects to see ultraviolet (UV) light as well as blue and green. New research led by Camilla Sharkey, a postdoctoral associate at the Wardill Lab in the College of Biological Sciences, investigated the complex evolutionary history of jewel beetles’ vision. The research team included Jorge Blanco, formerly with the Wardill Lab ...

Prenatal exposure to anti-nausea drug in ‘60s, ‘70s tied to increased risk of colorectal cancer
2023-03-10
Prenatal exposure to an anti-nausea drug commonly used in the 1960s and 1970s has been shown to increase risk of colorectal cancer in adult offspring, according to a study by researchers at UTHealth Houston.
The study, led by Caitlin Murphy, PhD, MPH, associate professor at UTHealth Houston School of Public Health, was published today in JNCI Cancer Spectrum.
Incidence rates of colorectal cancer are increasing among adults born in and after the 1960s, which Murphy said implicates pregnancy-related exposures introduced at that time as risk factors. Dicyclomine – used to treat spasms caused by irritable bowel syndrome – was initially ...

Meta-analysis shows association between autism in children and cardiometabolic diseases
2023-03-10
A study conducted by the Centers for Disease Control and Prevention (CDC) from 2009 to 2017 determined that approximately 1 in 44 children ages 3-17 are diagnosed with some form of autism spectrum disorder (ASD). Research also has established that children with ASD have an increased risk of obesity, and obesity has been linked to increased risks for cardiometabolic disorders such as diabetes and dyslipidemia (high level of cholesterol or fat in the blood). However, the question of whether or not there is an association between autism, cardiometabolic disorders and obesity remains largely unanswered.
To help provide an insight ...
Microbes can create a more peaceful world: Scientists call to action
2023-03-10
Microorganisms should be ‘weaponised’ to stave off conflicts across the globe, according to a team of eminent microbiologists.
The paper ‘Weaponising microbes for peace’ by Anand et al, outlines the ways in which microbes and microbial technologies can be used to tackle global and local challenges that could otherwise lead to conflict, but warns that these resources have been severely underexploited to date.

Immune cells have a backup mechanism
2023-03-10
The enzyme TBK1 is an important component of the innate immune system that plays a critical role in the defense against viruses. Upon mutation-induced loss of TBK1 function, patients show an increased susceptibility to viral infections. Strikingly, if TBK1 is not expressed at all, this clinical effect is not seen. The mechanism behind this supposed discrepancy has now been elucidated by researchers led by Prof. Martin Schlee from the University Hospital Bonn and the Cluster of Excellence ImmunoSensation2 at the University of Bonn. The study was published in the journal Frontiers in Immunology.
In the human body, viral particles are ...
Researchers discover therapeutic target to aid in glaucoma treatment
2023-03-10
INDIANAPOLIS—Indiana University School of Medicine researchers have identified a new therapeutic target that could lead to more effective treatment of glaucoma.
Glaucoma is a neurodegenerative disease that causes vision loss and blindness due to a damaged optic nerve. More than 200,000 people are affected by glaucoma in the United States each year. Unfortunately, there is currently no treatment. In a newly published paper in Communications Biology, researchers found neurons use mitochondria for a steady source of energy, and restoring mitochondrial homeostasis in the diseased neurons can protect the optic nerve cells from being damaged.
“Age-related ...
Medicaid expansion reduced black-white disparities in preventable hospital visits
2023-03-10
Expanding Medicaid-benefit eligibility to cover all people with income below 139 percent of the federal poverty line reduced Black-white disparities in preventable hospitalizations and emergency department (ED) visits, according to research from Rutgers University and the U.S. Agency for Healthcare Research and Quality.
The analysis of state-level inpatient and ED data from 2011 to 2018 showed that such disparities fell 10 percent or more in states that expanded eligibility compared to states that continued with older, stricter requirements.
Benefit expansion didn’t affect the relatively smaller disparities in preventable hospitalizations and ED visits between ...
New study challenges our understanding of the immune system
2023-03-10
A recently published study from Aarhus University may mean a textbook chapter on the immune system will have to be rewritten.
In the study, published in the journal Nature Communications, the researchers reveal crucial new knowledge about B cells, which form a vital element in the body’s defence system. B cells are the cells that generate protective antibodies when we are vaccinated or have an infection – and it is also the B cells that produce harmful antibodies in connection with allergies or autoimmune diseases.
The researchers have examined the earliest step ...

Insurance status and race, ethnicity inequities in the diagnosis of advanced cervical cancer
2023-03-10
About The Study: The findings of this study of nearly 24,000 individuals suggest that insurance is a modifiable risk factor that plays an important role in the racial and ethnic inequities observed in the diagnosis of advanced-stage cervical cancer. Expanding access to care and improving the quality of services rendered for uninsured patients and those covered by Medicaid may mitigate the known inequities in cervical cancer diagnosis and related outcomes.
Authors: Hunter K. Holt, M.D., M.A.S., of the University of Illinois at Chicago, is the corresponding author.

Association of primary care visit length with potentially inappropriate prescribing
2023-03-10
About The Study: In this study of 4.3 million patients, those who were younger, publicly insured, Hispanic, or non-Hispanic Black had shorter primary care physician visits. Shorter visits were associated with a higher likelihood of inappropriate antibiotic prescribing for patients with upper respiratory tract infections and co-prescribing of opioids and benzodiazepines for patients with painful conditions. These findings suggest opportunities for additional research and operational improvements to visit scheduling and quality of prescribing decisions ...
Neutrons reveal how the spider lily preys on cancer, preserves healthy cells
2023-03-10
A scientific instrument at the Department of Energy’s Oak Ridge National Laboratory could help create a noninvasive cancer treatment derived from a common tropical plant.
Pancratistatin is a chemical compound found in the spider lily, a native Hawaiian flower. Unlike traditional treatments, it kills cancer cells while keeping healthy cells intact.
Until recently, pancratistatin’s workings have mystified scientists, clouding hope for potential new treatments. But after conducting neutron experiments at ORNL, students from the University of Windsor have ...
Migratory birds take breaks to boost their immune system
2023-03-10
Exercising too much and not getting enough rest is bad for your health. A new study from Lund University in Sweden shows that the same is true for migratory birds. They need to rest not only to renew their energy levels but also in order to boost their immune system.
After a period of physical exertion, vertebrates, including humans, usually need a period of recovery. Apart from the obvious – lowering the heart rate and repairing injured muscles – other, less prominent physiological systems might also need to recover. Intensive physical activity can affect an individual’s basic immune defence.
When birds migrate, they regularly stop in one place for a ...
Hotter than infinity – light pulses can behave like an exotic gas
2023-03-10
In the issue of the renowned journal Science published today (10.3.23), the team led by Prof. Dr Ulf Peschel reports on measurements on a sequence of pulses that travel thousands of kilometres through glass fibres that are only a few microns thin. The researchers were surprised by the results. “We have found that the light pulses organize themselves after about a hundred kilometres and then behave more like molecules of a conventional gas, such as air, for example”, reports Prof. Ulf Peschel, the head of the group in Jena. In a gas the particles move back ...
Cause of leukemia in trisomy 21
2023-03-10
FRANKFURT. Leukaemia (blood cancer) is a group of malignant and aggressive diseases of the blood-forming cells in the bone marrow. Very intensive chemotherapy and in some cases a bone marrow transplant are the only cure. Like all cancers, leukaemia is caused by changes in the DNA, the heredity material present in human cells in the form of 46 chromosomes. In many forms of leukaemia, large parts of these chromosomes are altered. People with Down syndrome, who have three copies of chromosome 21 (trisomy 21) are highly vulnerable: ...
A study analyzes the notion of spectacle through the figure of Antigone
2023-03-10
A research study at Universidad Carlos III de Madrid (UC3M) analyzes the notion of spectacle as an enunciative space that is located beyond mediatic logic. In contrast to the generalized concept of spectacle laden with negative connotations, the study proposes a distancing of that concept from that of entertainment. UC3M Full Professor Pilar Carrera, in her essay Antígona o la razón espectacular (2023), published in the review Signa,advocates the notion of spectacle from the perspective of spectacular distance ...
Outperforms state-of-the-art algorithms in deep learning tasks
2023-03-10
Deep learning based semi-supervised learning algorithms have shown promising results in recent years. However, they are not yet practical in real semi-supervised learning scenarios, such as medical image processing, hyper-spectral image classification, network traffic recognition, and document recognition. In these types of scenarios, the labeled data is scarce for hyper-parameter search, because they introduce multiple tunable hyper-parameters. A research team has proposed a novel meta-learning based semi-supervised learning algorithm called Meta-Semi, that requires tuning only one additional hyper-parameter. Their Meta-Semi approach outperforms state-of-the-art ...
Social intelligence is the next frontier for AI, researchers say
2023-03-10
Siri and Google Assistant may be able to schedule meetings on request, but they don’t have the social understanding to independently prioritize the appointments — yet. According to researchers based in China, artificial intelligence (AI) may be smart, but it is stunted by a lack of social skills.
They published their review of the current state and call for future directions on March 10 in CAAI Artificial Intelligence Research.
“Artificial intelligence has changed our society and our daily life,” said first author Lifeng Fan, National Key Laboratory of General Artificial Intelligence, Beijing Institute for General Artificial ...
