Published Making gluten-free, sorghum-based beers easier to brew and enjoy
(via sciencedaily.com) Original source Though beer is a popular drink worldwide, it's usually made from barley, which leaves those with a gluten allergy or intolerance unable to enjoy the frothy beverage. Sorghum, a naturally gluten-free grain, could be an alternative, but complex preparation steps have hampered its widespread adoption by brewers. Now, researchers reporting the molecular basis behind sorghum brewing have uncovered an enzyme that could improve the future of sorghum-based beers.
Published Researchers engineer colloidal quasicrystals using DNA-modified building blocks
(via sciencedaily.com) Original source A new study unveils a novel methodology to engineer colloidal quasicrystals using DNA-modified building blocks. The implications of this breakthrough are far-reaching, offering a potential blueprint for the controlled synthesis of other complex structures previously considered beyond reach.
Published Strawberry consumption may reduce dementia risk for middle-aged individuals
(via sciencedaily.com) Original source New research found that daily strawberry consumption could help reduce the risk of dementia for certain middle-aged populations.
Published First mice engineered to survive COVID-19 like young, healthy humans
(via sciencedaily.com) Original source Researchers have genetically engineered the first mice that get a human-like form of COVID-19, according to a new study.
Published Where is a sea star's head? Maybe just about everywhere
(via sciencedaily.com) Original source A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.
Published Pinpointing HIV immune response
(via sciencedaily.com) Original source New research combining computer modeling and experiments with macaques shows the body's immune system helps control human immunodeficiency virus (HIV) infections largely by suppressing viral production in already infected cells while also killing viral infected cells, but only within a narrow time window at the start of a cell's infection.
Published Ocean warming is accelerating, and hotspots reveal which areas are absorbing the most heat
(via sciencedaily.com) Original source A new study reveals increasing warming rates in the world's oceans in recent decades and the locations with the greatest heat uptake.
Published Risk of serious infection even in low-active IBD
(via sciencedaily.com) Original source Inflammatory bowel disease (IBD) is an independent risk factor for serious infection, even at very low levels of gastrointestinal inflammation.
Published New Nijmegen method reveals hidden genetic variations
(via sciencedaily.com) Original source Many hidden genetic variations can be detected with Chameleolyser, a new method. The information is already yielding new patient diagnoses and may also lead to the discovery of as yet unknown disease genes.
Published Plastic-eating bacteria turn waste into useful starting materials for other products
(via sciencedaily.com) Original source Mountains of used plastic bottles get thrown away every day, but microbes could potentially tackle this problem. Now, researchers report that they've developed a plastic-eating E. coli that can efficiently turn polyethylene terephthalate (PET) waste into adipic acid, which is used to make nylon materials, drugs and fragrances.
Published Shifting nesting timing not enough to prevent fewer sea turtle hatchlings
(via sciencedaily.com) Original source New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.
Published How sunflowers see the sun
(via sciencedaily.com) Original source Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers 'see' the sun to follow it? Plant biologists show that they use a different, novel mechanism from that previously thought.
Published Scientists create special 'telomouse' with human-like telomeres
(via sciencedaily.com) Original source Researchers introduce the 'Telomouse'. By making a subtle genetic alteration in standard lab mice, they've made the mouse telomeres, which protect the chromosome ends, more closely resemble those in humans. The Telomouse model, developed by incorporating a genetic variation from a mouse species with naturally shorter telomeres, provides a valuable resource for in-depth aging and cancer research. This discovery promises to reveal new insights into the genetics of aging and may contribute to enhanced longevity and well-being.
Published Two bee species become one as researchers solve identity puzzle
(via sciencedaily.com) Original source A new study has found that what were thought to be two different species of native Australian bee are in fact one.
Published How to protect biocatalysts from oxygen
(via sciencedaily.com) Original source There are high hopes for hydrogen as the key to the energy transition. A specific enzyme group found in algae and in bacteria can produce molecular hydrogen simply by catalyzing protons and electrons. However, the enzyme group is so sensitive to oxygen that commercial use of the hydrogen produced by this process as a green energy source is not yet possible. Researchers have now increased the oxygen stability of a hydrogen-producing enzyme by genetically generated channel blockages.
Published Cat-ching criminals with DNA from pet hairs
(via sciencedaily.com) Original source Cat hair could be the purr-fect way to catch criminals, according to researchers.
Published Intestinal bacteria metabolite promotes capture of antigens by dendritic cells
(via sciencedaily.com) Original source Dendritic cells are immune cells that capture and present antigens to T cells, activating an immune response. Researchers have discovered that short-chain fatty acids produced by intestinal bacteria regulate a crucial step in this process, the extension of dendritic 'arms.' This breakthrough finding could potentially lead to the development of disease prevention strategies involving beneficial bacteria and new drugs targeting the regulation of dendritic cell function.
Published Controlling organoids with light
(via sciencedaily.com) Original source Organoids help researchers understand biological processes in health and in disease. It is, however, difficult to influence the way in which they organize themselves into complex tissues. Now a group has found a new way to do so.
Published Increasing risk of invasive species colonization on marine debris
(via sciencedaily.com) Original source A groundbreaking scientific study conducted along the Southeast coast of India has unearthed a pressing environmental concern -- the increasing risk of invasive species colonization on marine debris. The research delves into the critical interplay between plastic pollution and the introduction of non-indigenous organisms into Indian waters.
Published Meltwater flowing beneath Antarctic glaciers may be accelerating their retreat
(via sciencedaily.com) Original source A new Antarctic ice sheet modeling study suggests that meltwater flowing out to sea from beneath Antarctic glaciers is making them lose ice faster.
