Discovery opens possibility of new ion channel-targeting drugs

Ion channels are attractive drug targets due to their importance in health and disease, but finding ways to target a specific ion channel selectively is a major challenge. Now, researchers have discovered that ion channels called BK channels have unique openings in their sides, which drug molecules may be able to access. The finding could lead to the development of selective drugs that target the BK channel to treat a wide range of diseases.

Scientists detect and validate the longest-period exoplanet found with TESS

Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.

Unprecedented gamma-ray burst explained by long-lived jet

While astrophysicists previously believed that only supernovae could generate long gamma-ray bursts (GRBs), a 2021 observation uncovered evidence that compact-object mergers also can generate the phenomenon. Now, a new simulation confirms and explains this finding. If the accretion disk around the black hole is massive, it launches a jet that lasts several seconds, matching the description of a long GRB from a merger.

Energy-storing supercapacitor from cement, water, black carbon

Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.

Scientists uncover a startling--and exploitable--coordination of gene expression in tumors

A new study has identified a pair of genes whose expression by a type of immune cell within tumors is predictive of outcomes for cancer patients and is linked to a vast network of gene expression programs, engaged by multiple cell types in the tumor microenvironment, that control human cancers.

Winter storms over Labrador Sea influence Gulf Stream system

The Gulf Stream system plays an important role in climate. The weakening of this system that has been observed over the last two decades is therefore a cause for concern and much debate. The question is whether the measurable changes are already due to human-induced climate change -- model simulations predict such an influence with high probability for the future. A new study concludes that the currently observed weakening can be interpreted, at least in part, as a natural fluctuation following some extremely cold winters in the Labrador Sea in the 1990s.

Social media algorithms exploit how humans learn from their peers

In prehistoric societies, humans tended to learn from members of our ingroup or from more prestigious individuals, as this information was more likely to be reliable and result in group success. However, with the advent of diverse and complex modern communities -- and especially in social media -- these biases become less effective. For example, a person we are connected to online might not necessarily be trustworthy, and people can easily feign prestige on social media. Now, a group of social scientists describe how the functions of social media algorithms are misaligned with human social instincts meant to foster cooperation, which can lead to large-scale polarization and misinformation.

Butterfly-inspired films create vibrant colors while passively cooling objects

New films inspired by butterfly wings circumvent the heating effect usually experienced by colored objects absorbing light on a hot day. The new films could be used on the outside of buildings, vehicles and equipment to reduce the energy needed for cooling while preserving vivid color properties.

Gravitational arcs in 'El Gordo' galaxy cluster

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.

Nuclear spin's impact on biological processes uncovered

Researchers have discovered that nuclear spin influences biological processes, challenging long-held beliefs. They found that certain isotopes behave differently in chiral environments, affecting oxygen dynamics and transport. This breakthrough could advance biotechnology, quantum biology, and NMR technology, with potential applications in isotope separation and medical imaging.

Sweet smell of success: Simple fragrance method produces major memory boost

When a fragrance wafted through the bedrooms of older adults for two hours every night for six months, memories skyrocketed. Participants in this study reaped a 226% increase in cognitive capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive technique for strengthening memory and potentially deterring dementia.
