A team of astronomers studied two nearby globular clusters, 47 Tucanae and Omega Centauri, searching for signals produced by annihilating dark matter. Though the searches turned up empty, they weren't a failure. The lack of a detection placed strict upper limits on the mass of the hypothetical dark matter particle.

A trio of researchers from Queens College, City University of New York, the University of California, Los Angeles, and Stanford University has found that a citation bias exists in research papers and the problem is growing worse.

Compact terahertz functional devices are highly useful for high-speed wireless communication, biochemical sensing and non-destructive inspection. However, controlled terahertz generation, alongside transport and detection is challenging for chip-scale devices, due to low coupling efficiency and absorption losses.

Sweden is often lauded for its gender equality. The gender gap in unpaid (house)work is narrow. Wide access to affordable, state-subsidized daycare, together with the right for parents of young children to work part time, means that women's participation in the labor market is relatively high. And parental leave policies are generous.

Infectious microbes have evolved sophisticated means to invade host cells, outwit the body's defenses and cause disease.

Svåra skallskador leder i princip alltid till minnesproblem och upprepade slag mot huvudet höjer risken för demens, något som en uppmärksammad skotsk studie av elitidrottare satt fokus på.

Alla som har försökt ändra sina mat- eller träningsvanor vet hur svårt det är och hur lätt man faller tillbaka i gamla mönster. För den som fått diagnosen typ 2-diabetes är livsstilsförändringar absolut nödvändiga för att få kontroll över sitt blodsocker. Men det finns knep för att hitta motivationen till förändring.

– En del barn kan helt enkelt inte äta, säger Kajsa Lamm som forskar om barn med ätsvårigheter. Att kalla det för ätovilja eller matvägran menar hon är fel. Det antyder att barnet inte vill och att det är fel på barnets beteende vilket kan leda till att barnet inte får rätt hjälp.

På 1990-talet blev det känt att Medelhavskost, som är rik på bland annat fisk, olivolja och grönsaker, sänkte blodfetter och minskade risken för hjärtproblem. Ny forskning tyder på att nordisk kost fungerar likadant.

Alltför många äldre lider av undernäring. Samtidigt visar forskning att några extrakilon är bra för hälsan på ålderns höst. Sölve Elmståhl, professor i geriatrik vid Lunds universitet och läkare på Skånes universitetssjukhus, berättar varför goda kostvanor är extra viktigt för personer över 80 år.

Gurkmeja, bär och mörk choklad dyker upp om man googlar på antiinflammatorisk kost. Men det har varit svårt att visa att enskilda livsmedel har effekt mot inflammation i våra kroppar. Däremot kan sunda matmönster fungera.

Vilken mat ska vi äta för att hålla oss friska? Forskningsfrågan är enkel – men vägen till svaret är lång och komplicerad för nutritionsepidemiologen Emily Sonestedt. Fokus ligger inte bara på enskilda livsmedel och näringsämnen, utan också på matmönster.

Våra långtidsminnen är ristade i hjärnbarken. Varje gång vi återvänder till ett minne så blir kopplingarna till minnet allt fler, samtidigt som vi ändrar lite på det. Så våra starkaste minnen riskerar att bli mer och mer osanna.

Ur ett näringsperspektiv uppfattas många av oss som irrationella konsumenter som äter ohälsosamt för att vi inte förstår bättre och därför behöver utbildas. Men matetnologen Håkan Jönsson motsätter sig detta och menar att måltiden har flera andra minst lika viktiga funktioner.

Vid depression blir hjärnan uttröttad och minnet och koncentrationen fungerar inte som det ska. Problemen kan vara bestående. Forskningen satsar därför på att hitta lösningar på de koncentrations- och minnesproblem som ofta dröjer sig kvar under flera år.

De flesta av oss glömmer iblandar vi lagt mobilen eller nycklarna, eller något vi skulle handla i affären. Att glömma emellanåt är normalt och det finns många anledningar till ett tillfälligt sämre minne – sömnbrist och stress är två av dem. Men vad är skillnaden mellan att vara normalt glömsk och symtom på Alzheimers sjukdom, den vanligaste demenssjukdomen?

Minnet är inte perfekt. Vi kan både glömma och minnas fel. Men det är inte bara dåligt, säger minnesforskaren Mikael Johansson. Tvärtom kan det vara praktiskt och till och med bra för den psykiska hälsan.

Vem som drabbas av demens handlar både om livsstil, riskfaktorer och de gener du fått. Demens kan inte botas, men det går att göra saker som ökar chansen för fler friska år.

A hugely promising proof of concept.

Fysisk aktivitet är bra för minnet. Det är hjärnforskarna Tomas Deierborg och Tomas Roos eniga om. Både deras egen och andras forskning tyder på det. Och de lever så klart som de lär.

Alzheimers sjukdom blir allt vanligare i en åldrande befolkning. Förutom det personliga lidandet innebär det även stora kostnader för samhället. Därför läggs omfattande resurser på att hitta läkemedel som kan bromsa sjukdomen. Och det finns lovande resultat.

Trots en livslång kärlek till god mat, choklad och semlor har Kabuki Iwanaga klarat att lägga om sin kost. Kroppen har tackat för tappade kilon med bättre blodsocker, kolesterol och blodtryck. Själv tackar han det forskningsbaserade Livsstilsverktyget som i flera år inspirerat honom att hålla fast vid sina nya goda vanor.

Demens är en av Sveriges stora folksjukdomar. I takt med att vi lever allt längre får också allt fler lära sig leva med sjukdomen. Men trots en demenssjukdom kan livet ha mycket att ge.

Vid PTSD tar hemska minnesbilder upp för stor plats i hjärnan för att minnet ska fungera. Trots att det finns effektiv terapi vågar många inte genomgå den. Därför forskas det nu på mediciner som ska lindra den skräck som terapin väcker.

Med ett enkelt blodprov och några snabba minnestester kan Alzheimers sjukdom diagnostiseras – med samma träffsäkerhet som mer avancerade metoder. Nu ser forskarna bakom det diagnostiska verktyget fram emot att det börjar användas på vårdcentralerna.

Det finns en stark koppling mellan dofter och minnen. Samtidigt försämras luktsinnet med åldern och äldre kan därför behöva luktträna. Det gäller även de som lider av postcovid.

Nyheten om att svenskar äter mest ultraprocessad mat i EU fick stort utrymme i media. Men den bakomliggande klassificeringen kan vara felaktig.

Det har hänt en del sedan kostcirkeln lanserades i Sverige på 60-talet och råden om vad vi ska äta har förändrats i takt med att forskningen gått framåt. Men att forska på folks matvanor innebär en hel del utmaningar.

Vi är nog flera som känt oss grötiga i hjärnan i samband med att vi haft covid-19-infektion. För de flesta av oss var dessa svårigheter med minne och koncentration övergående. Men vad hände i hjärnan som gjorde att den inte fungerade lika bra som vanligt?

Överanvändningen av läkemedel som kan vara skadliga för äldre har minskat. Men fortfarande skrivs medicin med kognitiv påverkan ut för ofta till personer med demens. Det visar en studie av läkemedelsanvändning på demensboenden.

During the first years of their lives, children develop the cognitive, social and emotional skills that will provide the foundations for their lifelong health and achievements. However, exposure to environmental stressors during critical periods of life can have negative long-term consequences for their development. One of the most critical stressors for children is maternal stress, which is known

Medicare costs around the time of a dementia diagnosis are much lower for older adults screened proactively rather than those diagnosed while experiencing a health issue.

In recent years Alzheimer's disease has been on the rise throughout the world and is rarely diagnosed at an early stage when it can still be effectively controlled. Using artificial intelligence, researchers conducted a study to identify whether human-computer interfaces could be adapted for people with memory impairments to recognize a visible object in front of them.

The Tibetan Plateau (TP) is referred to as the "water tower" of Asia for being home to the headwaters of many major rivers in Asia, including the Yangtze, Yellow, Ganges, and Indus. Therefore, TP precipitation is important for not only local, but regional water resources too. On the other hand, the TP can strongly modulate the Asian climate through dynamic and thermal processes. Previous studies h

The great white shark could have helped push the megalodon to extinction through a battle for food.

This month: For scientists who come from abroad to live and work in America, accents can be personal. It's discouraging to be misunderstood, even when they think they're speaking clearly. Sometimes, it could even be a career liability. Is the problem the accent, or those on the receiving end?

The live chats of the past are now in our pockets and inescapable. We need better boundaries.

Cells rely on a process known as RNA interference (RNAi) to control protein production. The centerpiece of that process is the protein Argonaute, which seeks out and destroys mRNA molecules. Scientists have now discovered how Argonaute efficiently jumps from one target to the next. Their work may help improve current RNAi-based therapies and develop better ones in the future.

A new framework for managing obesity care in primary care settings, and efforts to educate clinicians about the appropriate use of obesity medications, aim to improve care for this chronic disease.

The nervous system is known to communicate with the immune system and regulate inflammation in the body. Researchers now show how electrical activation of a specific nerve can promote healing in acute inflammation.

A new study suggests that the European cuttlefish (sepia officinalis) may combine, as necessary, two distinct neural systems that process specific visual features from its local environment, and visual cues relating to its overall background environment to create the body patterns it uses to camouflage itself on the sea floor.

Combinatorial optimization problems are at the root of many industrial processes and solving them is key to a more sustainable and efficient future. Ising machines can solve certain combinatorial optimization problems, but their efficiency could be improved with multi-spin flips. Researchers have now tackled this difficult problem by developing a merge algorithm that disguises a multi-spin flip as

Energy costs keep on rising, so any way we can reduce the impact is welcomed. Energy-efficient light bulbs use anywhere from 70 percent to 90 percent less electricity than standard incandescent bulbs. While the purchase price may be a little higher, they are invariably cheaper over their lifespan. That lifespan is also 10 to 25 times longer, so they are both more convenient and better for the env

Strong precipitation or extreme drought—the frequency of extreme weather events is increasing worldwide. Existing climate models, however, do not adequately show their dynamics. Researchers of Karlsruhe Institute of Technology (KIT) assume that ultrafine particles in the atmosphere have a significant impact on cloud physics and, hence, on weather. Their aircraft measurements confirm an increase in

Cells produce proteins like little factories. But if they make too much at the wrong times it can lead to diseases like cancer, so they control production with a process called RNA interference (RNAi). As of July 2021, several drugs already take advantage of RNAi to treat painful kidney and liver diseases—with another seven in clinical trials. There is a lot of potential for RNAi therapeutics, and

Government coalitions often dissolve when too many parties disagree on too many issues. Even if a coalition seems stable for some time, a small crisis can cause a chain reaction that eventually causes the system to collapse. A study conducted in the Department of Physics at Bar-Ilan University demonstrates that this principle also holds true for ecosystems, particularly bacterial ecosystems.

New research calculates the odds that humans will contact a 'malicious' alien civilization that wants to invade our planet. Don't worry, the chances are incredibly small.

Today, the Salton Sea is an eerie place. Its mirror-like surface belies the toxic stew within. Fish skeletons line its shores and the ruins of a once thriving vacation playground is a reminder of better days. But long before agricultural runoff spoiled the Salton Sea, the lakebed it now occupies was home to a much larger body of water known as Lake Cahuilla. The lake was six times the area of the

Scientists have identified a new role for a protein complex at the center of a human genetic disorder called Bardet-Biedl syndrome, or BBS, for which there is currently no cure.

The diet of fossil extinct animals can hold clues to their lifestyle, behavior, evolution and ultimately extinction. However, studying an animal's diet after millions of years is difficult due to the poor preservation of chemical dietary indicators in organic material on these timescales. An international team of scientists led by the Max Planck Institute for Evolutionary Anthropology in Leipzig,
