Chemicals in some household products including shampoo, perfumes, deodorants and soaps could cause girls to start puberty early, a study has found.
The study, published in the journal Human Reproduction, examined chemical levels including phthalates, parabens and phenols.
Certain phthalates are used in some scented products such as perfumes, deodorants, soaps, shampoo, nail polish and cosmetics.
Parabens are often used as preservatives in cosmetics and other personal care products and phenols can be used in soap, toothpaste, lipsticks, hairsprays, shampoos and skin lotions.
Researchers observed 179 girls and 159 boys in California born to mothers pregnant between 1999 and 2000.
The team studied the levels of chemicals in the mothers during pregnancy and in the children at nine years old.
They then tracked onset of puberty and found exposure to certain chemicals was linked to the early onset of puberty in girls but no evidence that chemical exposure affected boys.
Lead researcher Dr Kim Harley, associate professor in public health at the University of California, said they found two chemicals were particularly significant.
“Mothers who had higher levels of two chemicals in their bodies during pregnancy – diethyl phthalate, which is used in fragrance, and triclosan, which is an antibacterial agent in certain soaps and toothpaste – had daughters who entered puberty earlier,” she said.
“We also found that girls with higher levels of parabens in their bodies at the age of nine entered puberty earlier,” she added.
Dr Harley said the study may help explain why the age at which puberty starts in girls has been getting earlier in the last few decades, which has harmful side effects.
“One hypothesis is that chemicals in the environment might be playing a role, and our findings support this idea,” she said.
“Earlier puberty in girls increases their risk of mental health problems and risk-taking behaviour as teenagers and increases their risk of breast and ovarian cancer over the long-term, so this is an important issue to address,” she added.
World’s oldest known bird lays another egg
The world’s oldest known bird is set to become a mother again – after raising at least 30 other youngsters.
Wisdom the albatross has laid another egg at her nest site in Midway Atoll National Wildlife refuge on a tiny island about 1,200 miles northwest of Hawaii, in the Pacific Ocean.
Biologists believe Wisdom is at least 68 years old, forcing them to re-evaluate the age which they expected albatrosses to live to.
Albatross mate for life, but will recouple if a partner dies. The current age of her mate Akeakamai is not known, but the pair have been together since 2006.
“She first appeared back at her traditional nest site on November 29 and biologists on Midway have confirmed that she has laid an egg,” a statement from the US Fish and Wildlife Service Pacific Region said.
“Wisdom and her mate Akeakamai return to the same nest site on Midway Atoll each year. Biologists call this type of behavior ‘nest site fidelity’.”
Albatross lay a single egg and incubate it for just over two months before they spend another five months rearing it to fledgling status after it hatches.
During that time, Wisdom and Akeakamai will take it in turns to sit on the egg or tend to the chick as the other searches for food at sea.
It is thought that Wisdom, a Laysan albatross, has reared between 30 and 36 chicks in her life.
The chick she produced in 2001 was observed just a few feet away from her in 2017, providing further evidence that albatross offspring return to their parents as they get older.
“Midway Atoll’s habitat doesn’t just contain millions of birds, it contains countless generations and families of albatrosses,” said Kelly Goodale, US Fish and Wildlife Service Refuge biologist.
“If you can imagine when Wisdom returns home she is likely surrounded by what were once her chicks and potentially their chicks. What a family reunion!”
The USFWS says nearly 70% of the world’s Laysan albatross and almost 40% of black-footed albatross rely on the reserve.
There are around three million birds on the atoll, about 1.2 million of which are albatross – providing a crucial refuge for the birds, most species of which are at risk due to loss of habitat, ocean plastic and commercial fishing practices, according to the WWF.
Wisdom was first ringed in 1956 at a time when Midway Island was a strategic outpost for the US Navy.
The biologist who ringed her then rediscovered her 46 years later in 2002 while surveying an area he had previously visited.
It was because she was a fully developed adult bird when he first saw her that he was able to determine her minimum age.
In 2006, she was seen again and from that point, after her age was recognised, she began to be monitored regularly.
While the Laysan albatross does not have the wingspan of the wandering albatross – the largest wingspan of any bird – like other species they spend most of their lives in flight over the oceans.
It is thought Wisdom has travelled more than three million miles in her lifetime.
Soap star questioned and two held after diamond trader found dead in forest
A soap star has been questioned by police while a former ministerial aide and a policeman have been arrested over the alleged murder of a diamond trader.
Mumbai police detained actress Devoleena Bhattacharjee, who stars in popular Indian drama Saath Nibhana Sathiya, and quizzed her for several hours over the death of Rajeshwar Udani, officials reportedly said on Saturday.
The Times of India reported that the 28-year-old was the girlfriend of Sachin Pawar, who used to work as a personal assistant to the ruling Bharatiya Janata Party’s (BJP) Prakash Mehta.
NDTV reported that Pawar is also an acquaintance of the diamond merchant.
The broadcaster said authorities were remaining tight-lipped on her role in the case but hinted other women from the entertainment business could be questioned.
The investigation comes after the 57-year-old diamond trader’s heavily decomposed body was found in a forest on 5 December in the Raigad district of Maharashtra. He had been reported missing on 28 November.
He was found without any apparent injuries and without any ID. His son identified him from the clothes and shoes he was wearing.
After he had been missing almost a week, police said they were investigating a kidnapping.
Mr Udani’s driver reportedly told police that the businessman had asked to be dropped near the Pant Nagar market where he got into another vehicle.
Media reports say detectives believe Mr Udani may have been killed at another location before being dumped in the forest.
Call records reportedly showed the businessman was a regular at several bars and was in touch with women from the entertainment business through Pawar.
After being released, Bhattacharjee thanked concerned fans on Twitter, saying she was “safe and home”.
“There is nothing to get worried about,” she wrote. “It was an investigation as I know the person who got killed… an official statement has been already given by the department… All is well!!:)”
Police warning as child caught on CCTV being told to steal parcels
Police in Maryland have warned residents to be on alert for parcel thieves after a young girl was seen on CCTV being directed to steal packages from a porch.
Officers released footage of the incident at an apartment block in Bel Air as they urged people to be extra vigilant over the Christmas period.
The girl, who is believed to be around eight, was spotted running towards the property, then looking back to get directions, before taking the parcel.
The Harford County Sheriff’s Office wrote on Facebook: “We always warn you about package Grinches this time of year, but it’s hard to believe that a Grinch decided to use Cindy Lou Who this year to steal packages!
“Who uses a child in this manner?
“Please be aware of your surroundings, look for suspicious activity in your neighbourhood, and have packages delivered to a safe and secure location if you can.
“Remember, if you see something suspicious, call us.”
The incident happened on 30 November around midday at Inez Court in Bel Air.
