Study identifies new findings on implant positioning and stability during robotic-assisted knee revision surgery

18/01/2024
An innovative study explores the use of robotic-assisted joint replacement in revision knee scenarios, comparing the pre- and post-revision implant positions in a series of revision total knee arthroplasties (TKA) using a state-of-the-art robotic arm system.

Nearly dead plants brought back to life: Keys to aging hidden in the leaves

18/01/2024
Scientists have known about a particular organelle in plant cells for over a century. However, scientists have only now discovered that organelle's key role in aging.

Rain can spoil a wolf spider's day, too

18/01/2024
Researchers found that wolf spiders can't signal others or perceive danger from predators as easily on rain-soaked leaves compared to dry ones. Even communicating with would-be mates is harder after it rains.

New vaccine design uses immunity against influenza to offer faster protection against emerging pathogens

18/01/2024
Imagine a vaccine that speeds up the production of antibodies against SARS-CoV-2, the virus that spreads COVID-19. A research team has developed such a vaccine by using preexisting immunity to a separate virus (the influenza virus) to help kickstart the process of making antibodies against SARS-CoV-2.

Origin of intense light in supermassive black holes and tidal disruption events revealed

18/01/2024
A new study is a significant breakthrough in understanding Tidal Disruption Events (TDEs) involving supermassive black holes. The new simulations accurately replicate the entire sequence of a TDE from stellar disruption to the peak luminosity of the resulting flare.

Astronomers detect oldest black hole ever observed

18/01/2024
Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death.

Chemists create a 2D heavy fermion

18/01/2024
Researchers have synthesized the first 2D heavy fermion. The material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), has electrons that are 1000x heavier and is a new platform to explore quantum phenomena.

Therapy versus medication: Comparing treatments for depression in heart disease

18/01/2024
New research shows that behavioral activation therapy is as effective as antidepressant medications in treating symptoms of depression in patients with heart failure.

Higher measurement accuracy opens new window to the quantum world

18/01/2024
A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).

Climate change isn't producing expected increase in atmospheric moisture over dry regions

18/01/2024
The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected.

The metalens meets the stars

18/01/2024
Researchers have developed a 10-centimeter-diameter glass metalens that can image the sun, the moon and distant nebulae with high resolution. It is the first all-glass, large-scale metalens in the visible wavelength that can be mass produced using conventional CMOS fabrication technology.

Metastatic breast cancer treatments have aided decline in deaths

18/01/2024
Treatment of metastatic disease is responsible for nearly one-third of the decrease in annual deaths from breast cancer from 1975 to 2019, according to a new study.

Ultrafast laser pulses could lessen data storage energy needs

18/01/2024
A discovery from an experiment with magnetic materials and ultrafast lasers could be a boon to energy-efficient data storage.

Study throws our understanding of gene regulation for a loop

18/01/2024
To function properly, the genetic material is highly organized into loop structures that often bring together widely separated sections of the genome critical to the regulation of gene activity. Scientists now address how these loops can help repress or silence gene activity, with potentially far-reaching effects on human health.

Spider venom heart drug a step closer

18/01/2024
A molecule sourced from funnel web spider venom shows promise as a safe and effective future drug for heart attacks.

Machine learning reveals sources of heterogeneity among cells in our bodies

18/01/2024
A team of scientists discovered the secrets of cell variability in our bodies. The findings of this research are expected to have far-reaching effects, such as improvement in the efficacy of chemotherapy treatments, or set a new paradigm in the study of antibiotic-resistant bacteria.

Males of newly described Australian burrowing scorpions have a big tail to tell

18/01/2024
A study has found some surprising features in two new species of burrowing scorpions, including a very strangely shaped 'tail tip' and some 'sexy' anatomy features. Terrestrial biologists have taken a closer look at two new species of the mysterious Urodacus genus of burrowing scorpions endemic to Australia -- only to find a big difference in their tails compared to other species.

A new targeted treatment calms the cytokine storm

18/01/2024
Researchers have discovered a novel treatment to relieve cytokine release syndrome (CRS), a life-threatening inflammation triggered by a serious infection or severe burn. Treatment with a short-acting antibody reduces the inflammatory effects of interleukin-6, a key cytokine in CRS while avoiding the side effects associated with previous longer-acting therapies.

Older adults who exercise with their spouse may be less physically active than those who exercise individually

18/01/2024
A study has found that older adults who exercise with their spouse achieve lower physical activity levels than older adults without their spouse. In a study of 240 participants in Singapore aged 54 to 72 years old, the researchers also found that those who received personalized feedback on their fitness trackers were more active than those who did not.

Perfecting 3D-printed blood vessels with pores

18/01/2024
Due to the substantial clinical demand for artificial small-diameter vessels (SDVs), numerous commercial products have emerged. However, the majority of existing artificial SDVs lack an endothelial layer, leading to thrombosis. Fabricating artificial SDVs with a consistently uniform endothelial layer and adequate mechanical properties has proven exceptionally challenging. A research team has now induced spontaneous cell assembly and endothelialization through internal pores.
