Published in Cell Reports Medicine, the research from the Centre for Nutrition, Exercise, and Metabolism involved 53 healthy adults for up to 12 weeks. Participants followed either a moderate sugar diet (control), a low-sugar diet (less than 5% of calories from sugar), or a ketogenic (keto) low-carbohydrate diet (less than 8% of calories from carbohydrates).

Key findings include:

Increased Cholesterol: The keto diet raised cholesterol levels, particularly in small and medium sized LDL particles. The diet increased apolipoproteinB (apoB), which causes plaque buildup in arteries. In contrast, the low-sugar diet significantly reduced cholesterol in LDL particles.

A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed. This discovery suggests that the intense UV radiation from these flares could significantly impact whether planets around red dwarf stars can be habitable. Led by current and former astronomers from the University of Hawaii Institute for Astronomy (IfA), the research was recently published in the Monthly Notices of the Royal Astronomical Society.

“Few stars have been thought to generate enough UV radiation through flares to impact planet habitability. Our findings show that many more stars may have this capability,” said astronomer Vera Berger, who undertook the study while in the Research Experiences for Undergraduates program at IfA, an initiative supported by the National Science Foundation.

Berger and her team used archival data from the GALEX space telescope to search for flares among 300,000 nearby stars. GALEX is a now-decommissioned NASA mission that simultaneously observed most of the sky at near-and far-UV wavelengths from 2003 to 2013. Using new computational techniques, the team mined novel insights from the data.

Gold does not readily lend itself to being turned into long, thin threads. But researchers at Linköping University in Sweden have now managed to create gold nanowires and develop soft electrodes that can be connected to the nervous system. The electrodes are soft as nerves, stretchable and electrically conductive, and are projected to last for a long time in the body.

Some people have a “heart of gold,” so why not “nerves of gold”? In the future, it may be possible to use this precious metal in soft interfaces to connect electronics to the nervous system for medical purposes. Such technology could be used to alleviate conditions such as epilepsy, Parkinson’s disease, paralysis or chronic pain. However, creating an interface where electronics can meet the brain or other parts of the nervous system poses special challenges.

“The classical conductors used in electronics are metals, which are very hard and rigid. The mechanical properties of the nervous system are more reminiscent of soft jelly. In order to get an accurate signal transmission, we need to get very close to the nerve fibres in question, but as the body is constantly in motion, achieving close contact between something that is hard and something that is soft and fragile becomes a problem,” says Klas Tybrandt, professor of materials science at the Laboratory of Organic Electronics at Linköping University, who led the research.

Abstract. Feelings of love are among the most significant human phenomena. Love informs the formation and maintenance of pair bonds, parent-offspring attachments, and influences relationships with others and even nature. However, little is known about the neural mechanisms of love beyond romantic and maternal types. Here, we characterize the brain areas involved in love for six different objects: romantic partner, one’s children, friends, strangers, pets, and nature. We used functional magnetic resonance imaging (fMRI) to measure brain activity, while we induced feelings of love using short stories. Our results show that neural activity during a feeling of love depends on its object. Interpersonal love recruited social cognition brain areas in the temporoparietal junction and midline structures significantly more than love for pets or nature. In pet owners, love for pets activated these same regions significantly more than in participants without pets. Love in closer affiliative bonds was associated with significantly stronger and more widespread activation in the brain’s reward system than love for strangers, pets, or nature. We suggest that the experience of love is shaped by both biological and cultural factors, originating from fundamental neurobiological mechanisms of attachment.

From afar, the Sun looks calm and peaceful in our daytime skies. But up close, it’s an erupting, chaotic display of solar activity the likes of which astrophysicists didn’t expect until the last year or so.

“We didn’t think the Sun was going to be as active this particular cycle, but the observations are completely opposite,” Andrew Gerrard, the department chair and director of the Center for Solar-Terrestrial Research at New Jersey Institute of Technology, told Business Insider.

Solar cycles typically occur every 11 years. Within that time, the Sun oscillates from minimum to maximum solar activity, with maximum activity peaking in the middle of the cycle when the Sun’s magnetic fields flip.

A new vaccine designed to prime the immune system to recognise and fight lung cancer has been tested on UK patients for the first time.

Researchers leading the trial have said that BioNTech’s BNT116 vaccine could improve survival rates among people with the disease, and hope that it could eventually become the standard of care worldwide.

It works by presenting the immune system with tumour markers from non-small cell lung cancer, the most common form of the disease, to prime the body to fight cancer cells expressing these markers.

One of the oldest, scarcest elements in the universe has given us treatments for mental illness, ovenproof casserole dishes and electric cars. But how much do we really know about lithium?

We present the direct experimental observation of the formation of a diamagnetic cavity and magneto-Rayleigh-Taylor (MRT) instability in a betaapprox1 high energy density plasma. Proton radiography is used to measure the two dimensional path-integrated magnetic field in a laser-produced plasma propagating parallel to a preimposed magnetic field. Flutelike structures, associated with the MRT instability, are observed to grow at the surface of the cavity, with a measured wavelength of 1.2 mm and growth time of 4 ns. These measurements are in good agreement with predictions of three dimensional magnetohydrodynamic simulations using the GORGON code.
