Researchers identify how night-shift work causes internal clock confusion

Thursday October 22nd, 2020 04:31:16 PM
Night-shift workers face an increased risk of obesity and diabetes, but the underlying reason for that has been a mystery. Now, researchers have found a potential cause for metabolic changes during night-shift work that creates confusion between cells in the body and the central clock in the brain.

Are bushmeat hunters aware of zoonotic disease? Yes, but that's not the issue

Thursday October 22nd, 2020 04:31:13 PM
A recent article outlines how researchers with the measured the attitudes, practices and zoonoses awareness among community members associated with the bushmeat trade in northern Uganda.

Toward a new staging system for prostate cancer, and why it matters

Thursday October 22nd, 2020 04:31:11 PM
The development and validation of a staging system for non-metastatic prostate cancer could help doctors and patients assess treatment options, as well as improve clinical trials.

Simplified method to modify disease signaling with light

Thursday October 22nd, 2020 03:26:26 PM
Cellular optogenetics is a technique that allows researchers to use light to precisely control cell signaling and function in space and time enabling the investigation of mechanisms involved in disease processes. A research team has developed a novel way to make cellular optogenetic tools much easier to monitor and apply, and showed how they can be used to investigate the cellular side effects of medicines used to treat cancer.

Reviewing multiferroics for future, low-energy data storage

Thursday October 22nd, 2020 03:26:22 PM
Big data and exponential demands for computations are driving an unsustainable rise in global ICT energy use. A new study reviews the use of the 'multiferroic' material bismuth-ferrite, which allows for low-energy switching in data storage devices and could be applied in a future generation of ultra-low-energy electronics.

Cicada-inspired waterproof surfaces closer to reality

Thursday October 22nd, 2020 03:26:20 PM
A multidisciplinary group that studies the physical and chemical properties of insect wings has demonstrated the ability to reproduce the nanostructures that help cicada wings repel water and prevent bacteria from establishing on the surface. The new technique - which uses commercial nail polish - is economical and straightforward, and the researchers said it will help fabricate future high-tech waterproof materials.

Finally, a way to see molecules 'wobble'

Thursday October 22nd, 2020 03:26:18 PM
Researchers have found a way to visualize those molecules in even greater detail, showing their position and orientation in 3D, and even how they wobble and oscillate. This could shed invaluable insights into the biological processes involved, for example, when a cell and the proteins that regulate its functions react to a COVID-19 virus.

These two bird-sized dinosaurs evolved the ability to glide, but weren't great at it

Thursday October 22nd, 2020 03:26:13 PM
Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, researchers report. Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years. The findings support that dinosaurs evolved flight in several different ways before modern birds evolved.

A wearable sensor to help ALS patients communicate

Thursday October 22nd, 2020 03:26:09 PM
Researchers have designed a skin-like device that can be attached to the face and measure small movements such as a twitch or a smile. With this approach, patients with amyotrophic lateral sclerosis (ALS) could communicate a variety of sentiments with small movements that are measured and interpreted by the device.

Antiretroviral therapy can't completely stop accelerated cell aging seen in HIV

Thursday October 22nd, 2020 03:26:08 PM
Untreated HIV infection is linked with epigenetic changes that suggest rapid aging. A new study shows that antiretroviral therapy given over two years was unable to completely restore age-appropriate epigenetic patterns, leaving patients more susceptible to aging-related illnesses.

Simple actions can help people survive landslides

Thursday October 22nd, 2020 03:26:04 PM
Simple actions can dramatically improve a person's chances of surviving a landslide, according to records from 38 landslides in the US and around the world. People who survived landslides tended to show key behaviors such as being aware of the risk, moving to higher ground, and making noise if buried.

Researchers solve 'protein paradox' and suggest way to exploit cancer weakness

Thursday October 22nd, 2020 03:26:01 PM
Researchers have discovered how thus far a mysterious function of the so-called MCM proteins protect the human cells against DNA instability, which can cause devastating diseases including cancer. In addition to their known role as molecular motors of genome duplication, MCM proteins control the speed of this process. How cells manage to constrain the speed of DNA replication has puzzled researchers for decades and has even been called a 'MCM paradox'.

Social life as a driving factor of birds' generosity

Thursday October 22nd, 2020 03:25:57 PM
Taking a look at generosity within the crow family reveals parallels with human evolution. Working together to raise offspring and increased tolerance towards group members contribute to the emergence of generous behavior among ravens, crows, magpies and company. Biologists found that the social life of corvids is a crucial factor for whether the birds act generously or not.

Multiple sclerosis as the flip side of immune fitness

Thursday October 22nd, 2020 03:25:54 PM
About half of the people with multiple sclerosis have the HLA-DR15 gene variant. A study has now shown how this genetic predisposition contributes to the development of the autoimmune disease multiple sclerosis in combination with environmental factors. The decisive factor is the shaping of a repertoire of immune cells which - although they are effective in fighting off pathogens such as Epstein-Barr virus - also attack brain tissue.

New approach to fighting cancer could reduce costs and side effects

Thursday October 22nd, 2020 01:39:56 PM
Researchers have developed a novel approach based on microfluidic technology to 'purify' the immune cells of patients in the fight against cancer.

For the first time: Realistic simulation of plasma edge instabilities in tokamaks

Thursday October 22nd, 2020 01:39:54 PM
Among the loads to which the plasma vessel in a fusion device may be exposed, so-called edge localized modes are particularly undesirable. By computer simulations the origin and the course of this plasma-edge instability could now be explained for the first time in detail.

Optical wiring for large quantum computers

Thursday October 22nd, 2020 01:39:50 PM
Researchers have demonstrated a new technique for carrying out sensitive quantum operations on atoms. In this technique, the control laser light is delivered directly inside a chip. This should make it possible to build large-scale quantum computers based on trapped atoms.

Preventing lead poisoning at the source

Thursday October 22nd, 2020 01:39:44 PM
Using a variety of public records, researchers examined every rental property in Cleveland from 2016-18 on factors related to the likelihood that the property could have lead-safety problems.

Bacterial metabolism of dietary soy may lower risk factor for dementia

Thursday October 22nd, 2020 12:33:11 PM
A metabolite produced following consumption of dietary soy may decrease a key risk factor for dementia - with the help of the right bacteria, according to a new discovery.

Grafting with epigenetically-modified rootstock yields surprise

Thursday October 22nd, 2020 12:33:03 PM
Novel grafted plants -- consisting of rootstock epigenetically modified to 'believe' it has been under stress -- joined to an unmodified scion, or above-ground shoot, give rise to progeny that are more vigorous, productive and resilient than the parental plants.
